Wharton Sinkler : County Dark On Solar – The Conway Daily Sun

I recently accused the Carroll County Commissioners of “dereliction of duty” at a presentation for voters at the Gibson Center in Conway for failing to make a clear recommendation regarding installing a small solar array at the County Complex in Ossipee. That is a strong accusation and I’d like to defend it.
The solar array proposal was put together by me along with a team of four other volunteers as a service to Carroll County. It would have been a financial win for the county. Financially, the team’s proposal entailed two brief periods, in the first 12 years following installation of the array, when the county would have been “in the red.”

Distance mattered: the closer the solar array, the stronger the effect.

A new study finds that a home solar array can shape behavior beyond the property where it is installed. Nearby households may end up using less electricity and moving toward solar panels and electric vehicles as a result.
According to PV Magazine, the effect showed up in Switzerland, where homes near solar systems were more likely to cut power use, install panels of their own, and buy electric vehicles.
For the paper “Green spills: Peer effects in pro-environmental behaviors,” Benedikt Janzen of Germany’s University of Passau and Patrick Bigler of Switzerland’s University of Lausanne used geocoded records from 260,000 households in Switzerland’s canton of Bern spanning 2008 to 2019.
Using data on electricity consumption, solar ownership, EV ownership, and household characteristics, they examined how nearby solar adoption related to household behavior. One additional installation 328 feet (100 meters) from a home was linked to a 0.21% yearly decline in electricity use, or about 11 kilowatt-hours saved per household.

If you’re considering it, EnergySage can help you get free solar installation estimates and compare quotes.
Distance mattered: the closer the solar array, the stronger the effect. An installation within 33 feet (10 meters) of a household was associated with a 2.1% annual reduction in electricity use, plus a bigger jump in the odds that neighbors would install solar or buy an EV.
The starting adoption rates were modest.
“Although the magnitude of these effects appears small, they are relatively large in comparison to the baseline probabilities of 1% for solar PV and 0.44% for EV adoption,” the research paper says. “Put differently, an additional solar PV installation at 100 meters distance to a household leads to a significant increase in both the probability of adopting a solar PV and an EV by 2% and 2.3%, respectively.”
FROM OUR PARTNER
Want to go solar but not sure who to trust? EnergySage has your back with free and transparent quotes from fully vetted providers that can help you save as much as $10k on installation.
To get started, just answer a few questions about your home — no phone number required. Within a day or two, EnergySage will email you the best local options for your needs, and their expert advisers can help you compare quotes and pick a winner.
At that 33-foot (10-meter) range, the study associated a nearby installation with a 20% increase in solar adoption and a 23% increase in EV adoption.
A visible rooftop array also works as a signal that cleaner technology is practical, normal, and financially worthwhile.
For people thinking about making the switch, EnergySage can help homeowners go solar by letting them compare competitive bids from local installers without the companies getting their contact information unless they choose to work with one further. Its services are free to use, and with EnergySage’s help, the average person can save up to $10,000 on solar purchases and installations. That can make it much easier to compare options before committing to a major upgrade.
Readers can also use EnergySage’s solar map, which shows the average cost of a home solar panel system on a state-by-state level, as well as details on solar panel incentives for each state. Together, these resources can help readers get the best price for rooftop solar panels and access available incentives.
💡Go deep on the latest news and trends shaping the residential solar landscape
Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save money on energy, and go off-grid. It can also help households use more of the electricity they generate themselves. Homeowners can explore EnergySage for information about home battery storage options, including competitive installation estimates.
In the researchers’ words, “Overall, our research suggests that the benefits of residential solar PV adoption extend beyond the household installing the solar PV system because it encourages other households to act more pro-environmental.”
Rooftop solar’s ripple effects show up in a few different ways. The articles here look at how it can affect household budgets, shape public perception, depend on policy incentives, and come down to the cost comparisons that often determine whether a system gets installed.
• Across the US, rooftop solar can ease energy burdens for low- and moderate-income households.
• Experts say rooftop panels stay quiet enough that nearby neighbors may barely notice.
• In the US, federal solar tax credits remain central to homeowner installation decisions.
• EnergySage shows how installation costs vary with equipment, labor, and local market conditions.
Read together, these stories help explain why one rooftop array can matter beyond a single address. Solar adoption is shaped by a mix of economics, visibility, and policy, and those same factors often decide whether neighbors decide to make the leap.

California advocates fear federal review could strip coastal commission's say on drilling – The Cool Down

Oil and gas proposals could face fewer obstacles despite local opposition.

The Trump administration has opened a federal review of California’s coastal management program, raising fears that federal officials could weaken the California Coastal Commission’s authority over federally connected projects along the coast as they push for more offshore drilling and other fossil fuel activity in the state.
If that happens, Californians could lose a key voice in decisions that shape everything from public shoreline access to spill risks to the future of clean energy.
As the administration pushes for more oil activity in California, it has also opened a federal reexamination of the state’s coastal management program.
The Associated Press reported that the effort includes offshore leasing, pipeline activity, and possible fracking off Ventura County, while critics fear the review could shrink the California Coastal Commission’s authority over federally tied coastal projects.
That concern centers on the commission’s long-standing influence over shoreline development. Supporters say that if its role is weakened, oil and gas proposals could face fewer obstacles despite local opposition.
“It’s just part of that overall belief that they have, that they’re going to get rid of renewables and go back to good old-fashioned fossil fuels, and what better place to start than California?” said Deborah A. Sivas, a professor of environmental law at Stanford Law School.

Commerce Secretary Howard Lutnick announced the review in May while criticizing the commission’s resistance to other projects, including an expanded SpaceX launch schedule from Vandenberg Space Force Base.
“Obstructionist policies that delay critical national infrastructure in the name of environmental extremism are unacceptable,” Lutnick said.
California’s coast supports tourism, recreation, habitat, and local economies, all of which industrial accidents can devastate.
In 2015, a pipeline rupture triggered one of California’s worst recent spill disasters, contaminating 150 miles of beaches between Santa Barbara and Los Angeles. The spill also damaged habitat used by endangered whales and sea turtles.
Meanwhile, California has been steering in the opposite direction on energy policy. Data from the California Energy Commission shows that renewable energy generated almost half of the state’s electricity in 2024. Alongside expanding offshore wind initiatives, the state has actively taken steps to curb reliance on gas-powered vehicles.
No state with one of these coastal management programs has previously been stripped of its authority to review federal projects.
“This isn’t about performance. This is about power. It’s about whether the Trump administration can strip California’s authority because they don’t like the answers the coastal commission gave to oil companies,” Maureen Ellenberger, a Santa Barbara resident, warned at a public hearing.
The National Oceanic and Atmospheric Administration is conducting the review, though it has not said when it expects to finish. State officials are fighting on several fronts, including a lawsuit over the federal government’s repurchase of an offshore wind lease that critics say undercuts cleaner energy development.
The coastal commission has kept weighing in on federal fossil fuel plans. After a lengthy public hearing, it unanimously voted against a proposal to frack from a 45-year-old platform in federal waters off Ventura County. DCOR said the project would increase daily production across 16 wells from 1,100 barrels to 4,000 barrels.
At the Santa Monica hearing, many Californians argued that the commission should keep its oversight role, saying communities would face more pollution risk and have less control over their coastline if the state loses that authority.
“This is just simply one of those cases where the juice isn’t worth the squeeze. It creates far too many opportunities for something to go wrong. When something does go wrong, it is our ocean, beaches, wildlife, and coastal economy that pay the price,” Coastal Commissioner Ray Jackson said during the Ventura County hearing.
The fight is also playing out in Sacramento, in local governments, and around specific offshore operators. Pressure to restart or expand drilling is colliding with efforts to keep coastal decisions in the hands of communities and state officials.
• California lawmakers launch inquiry into Sable Offshore as pressure builds to restart drilling.
• Along the Central Coast, lawmakers push to safeguard coastal waters before new drilling begins.
• Governor Gavin Newsom signs laws to give more authority to California local governments.
At the center of it all is a fight over who gets to shape California’s energy future. That question becomes even more important if federal officials succeed in weakening the state’s coastal oversight.

New electrode design increases battery energy density by up to 15% – pv magazine Global

From ESS News
A consortium led by Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has developed thicker battery electrodes that could increase cell-level energy density by 10% to 15% without adding weight.
The researchers demonstrated the concept in lithium-ion, sodium-ion, and zinc-ion cells. They also manufactured lithium-ion pouch-cell prototypes.
“The new cell architecture was developed with future mass production in mind: A potential electrode production line exhibits significantly lower process complexity compared to a state-of-the-art wet-coating system,” Fraunhofer ISE said in a statement. “As a result, capital costs are significantly lower. Operating costs are also lower because it requires less space and energy. This technology thus opens up the possibility, particularly for small and medium-sized enterprises, to establish their own battery cell production facilities in Germany.”
Oliver Fitz, group leader for battery cell technology at Fraunhofer ISE, said the researchers increased electrode coating thickness from the conventional range of 100 µm to 200 µm to as much as 800 µm. The thicker electrodes reduce the number of current collectors required inside a cell, leaving more space and weight for active energy-storing material.
The resulting battery cells are also PFAS-free and are manufactured without toxic solvents. PFAS, or per- and polyfluoroalkyl substances, are a large group of synthetic chemicals that are highly persistent in the environment and are often referred to as “forever chemicals.”
The research team developed the electrode and cell design as part of three projects: “VORAN – Innovative Sodium-Ion Battery Storage for Stationary and Mobile Applications,” “INFAB – Zinc-Ion Batteries for Stationary Energy Storage – Manufacturing and Assembly,” and “WinZIB2 – Globally Deployable, Innovative Zinc-Ion Battery System.”
Project partners include Acp systems, Helmut Hechinger, the University of Stuttgart‘s Institute for Photovoltaics (ipv), and the Karlsruhe Institute of Technology/Helmholtz Institute Ulm.
“In a climate-neutral energy system with fluctuating energy sources like solar and wind, stationary battery storage is an integral component for covering morning and evening electricity peaks,” said Andreas Bett, director of Fraunhofer ISE. “Germany would be well advised to build up manufacturing capacity to meet the growing demand for batteries and thereby create value within the country. If we can contribute to that, we’d be very happy.”

Some Like It Hot: Agrivoltaics Grow More Hot Peppers – Yahoo News UK

Enjoying a spicy pepper
Solar energy is the cheapest in history, but it does have some issues. A continuing challenge in large-scale solar photovoltaic (PV) deployments is land use, which can be overcome with agrivoltaics particularly when integrated into controlled environmental agriculture. Agrivoltaics is the combination of solar energy and agriculture. Many crops increase their output with solar in the fields but less has been done with solar panels integrated into greenhouse rooftops. For greenhouse rooftops generally semi-transparent solar panels are used. Agrivoltaic greenhouses work well with tomatoes. Peppers are another common food crop grown in controlled environmental agriculture like greenhouses, but research investigating impacts of different semi-transparent photovoltaic agrivoltaic systems on hot peppers in northern regions was lacking. For this, a new study investigated the impact of partial solar shading on hot peppers in greenhouse.
In the study a group of six semi-transparent photovoltaic modules with different materials, transparencies, and spectrum filtrations were deployed in greenhouses to compare their impacts on an Italian spicy peppers, Piccante De Cayenna, with those in the control greenhouse in Ilderton, Ontario.
Plant height, leaf chlorophyll content, and fresh harvested weight were measured. All the agrivoltaic treatments increased yield, however, 50%-transparent thin film-blue increased by 78%, 69%-transparent, red-colored luminescent solar concentrator crystalline silicon increased by 91%, and 44%-transparent patterned crystalline silicon solar cells improved yields by 138% compared to controls. The bottom line is you can get more than twice as much peppers by choosing agrivoltaic shading carefully.
Rooftop agrivoltaic energy simulations were conducted in SAM for a 1-acre greenhouse model whose rooftops can be integrated by the top three performing agrivoltaic modules. 123 kWdc for 50%-thin film-blue would produce 137,452 kWh/acre (278% of greenhouse needs) and the 69%- luminescent solar concentrator -red would house 98 kWdc covering 99,182 kWh/acre that is more than 200% of needs, and finally 266 kWdc for the 44%-c-Si would generate 255,297 kWh/acre annually and potentially produce over 516% of the greenhouse's annual loads. All three of the top selections could power the greenhouses and have energy left over for other applications or to feet back to the grid.
The study concluded that the agrivoltaic greenhouses with semi-transparent solar modules that produced the highest yield of spicy peppers could also operate as net-sustainable energy exporters.

According to the latest IndexBox report on the global Steel Mounting Brackets Photovoltaic market, the market enters 2026 with broader demand fundamentals, more disciplined procurement behavior, and a more regionally diversified supply architecture.
The world steel mounting brackets photovoltaic market is entering a phase of sustained expansion, underpinned by the accelerating global transition to solar energy. As photovoltaic capacity additions continue to climb, the structural hardware that anchors and supports solar panels is becoming an increasingly critical component of the balance-of-system. This report analyzes the market from 2026 to 2035, providing a comprehensive view of demand drivers, supply dynamics, trade flows, and competitive positioning. The market is projected to double in volume by 2035, reaching 12 to 15 million metric tons, as annual solar installations exceed 600 GW in 2026 and continue their upward trajectory.
Key growth factors include the declining levelized cost of solar energy, aggressive decarbonization mandates across major economies, and the rising penetration of single-axis tracker systems, which require heavier and more standardized steel components. China remains the dominant production hub, accounting for over 60% of global manufacturing capacity, though trade barriers and localization incentives are gradually reshaping supply chains toward regional clusters.
The report segments demand by end-use sectors, including utility-scale ground-mount projects, commercial and industrial rooftops, residential installations, floating solar, and agrivoltaics, each with distinct structural requirements and growth prospects. It also examines the impact of advanced corrosion-resistant coatings, such as zinc-aluminum-magnesium and hot-dip galvanizing, which add 10-20% to unit costs but extend system lifespan in harsh environments. Steel price volatility and trade fragmentation remain key challenges, yet the overall outlook is robust, with innovation in product design and manufacturing processes enabling suppliers to meet the evolving needs of the solar industry.
The baseline scenario for the steel mounting brackets photovoltaic market points to robust growth through 2035, with global volume expected to double from 6-8 million metric tons in 2026 to 12-15 million metric tons by 2035. This translates to a compound annual growth rate of approximately 7-8% over the forecast period, driven by sustained increases in solar PV capacity additions worldwide. The market is supported by several structural factors: the continued cost competitiveness of solar energy, policy commitments to net-zero emissions, and the growing preference for utility-scale ground-mount installations that demand heavy-gauge steel brackets.
Single-axis tracker systems, which require more robust structural support, are expected to capture a larger share of new installations, further boosting steel intensity per megawatt. Regional dynamics will shift as localization policies in the United States, European Union, and India encourage domestic manufacturing, while China’s dominance in production gradually moderates. The commercial and industrial segment will also contribute to growth, particularly in regions with high electricity prices and corporate renewable procurement targets.
However, the market faces headwinds from steel price volatility, which has historically fluctuated by 40-60% within single years, creating margin pressure for fixed-price contracts. Trade barriers, including anti-dumping duties on Chinese-origin racking, are fragmenting global supply chains and raising compliance costs. Despite these challenges, technological advancements in corrosion-resistant coatings and modular mounting designs are expected to create premium product segments growing 2-3% faster than standard grades.
Overall, the market is poised for steady expansion, with opportunities for manufacturers that can offer integrated solutions, ensure supply chain resilience, and adapt to regional certification requirements.
Utility-scale ground-mount solar parks are the largest consumer of steel mounting brackets, accounting for over half of global volume. These projects require heavy-gauge steel rails, piles, and clamps to support thousands of PV modules across vast areas. The trend toward single-axis trackers, which optimize energy yield by following the sun, has increased the steel intensity per megawatt, as trackers demand more robust structural components to withstand wind and mechanical loads. Through 2035, this segment will continue to expand as countries build gigawatt-scale solar farms to meet decarbonization targets.
Demand-side indicators include the pipeline of announced utility-scale projects, auction results, and corporate power purchase agreements. Manufacturers are responding with high-throughput roll-forming lines to produce standardized components at scale, while also offering integrated solutions that include fasteners and grounding hardware to simplify procurement for EPC contractors. Current trend: Dominant and growing, driven by large solar parks and tracker systems.
Major trends: Shift toward single-axis tracker systems increasing steel demand per MW, Consolidation of procurement by large EPC contractors and developers, Adoption of advanced corrosion-resistant coatings for desert and coastal sites, and Localization of manufacturing to comply with trade policies.
Representative participants: Nextracker, Array Technologies, GameChange Solar, PV Hardware, and Schletter Group.
Commercial and industrial (C&I) rooftop solar installations represent a significant and growing share of steel mounting bracket demand. Businesses are increasingly installing solar to reduce energy costs, meet ESG targets, and hedge against volatile electricity prices. Rooftop systems require lightweight yet durable steel mounting solutions, including L-feet, rails, and clamps that can be installed without penetrating the roof membrane. The trend toward larger rooftop systems, often exceeding 1 MW, is driving demand for standardized steel components that can be quickly installed. Through 2035, the C&I segment will benefit from corporate renewable procurement and government incentives for distributed generation.
Demand-side indicators include commercial building construction, electricity tariff trends, and corporate sustainability commitments. Manufacturers are developing ballasted mounting systems for flat roofs and adjustable tilt brackets to optimize solar exposure, while also focusing on ease of installation to reduce labor costs. Current trend: Steady growth supported by corporate sustainability goals and high electricity prices.
Major trends: Growth of corporate power purchase agreements and on-site generation, Development of ballasted and non-penetrating mounting systems, Integration of solar with building management systems, and Rising demand for aesthetically pleasing and low-profile mounting designs.
Representative participants: Unirac, Ironridge, K2 Systems, Mounting Systems, and Schletter Group.
Residential solar installations account for a smaller but stable share of steel mounting bracket demand. Homeowners install solar to reduce electricity bills and increase energy independence, often supported by net metering policies and tax incentives. Residential systems typically use lighter steel rails and clamps, with a growing preference for integrated mounting solutions that are easy to install and aesthetically pleasing. The segment is mature in markets like Australia, Germany, and parts of the United States, but is expanding in emerging economies as financing options improve and electricity costs rise.
Through 2035, residential demand will be driven by the electrification of homes, including heat pumps and electric vehicles, which increases household electricity consumption and the value of rooftop solar. Demand-side indicators include residential construction, solar financing availability, and retail electricity rates. Manufacturers are focusing on pre-assembled kits and color-matched components to appeal to homeowners, while also ensuring compliance with local building codes and wind/snow load requirements. Current trend: Moderate growth, with increasing adoption of rooftop solar in emerging markets.
Major trends: Integration of solar with battery storage systems, Growth of community solar and virtual net metering, Development of solar shingles and building-integrated photovoltaics, and Increasing use of digital tools for system design and installation.
Representative participants: Ironridge, Unirac, K2 Systems, Clenergy, and Mounting Systems.
Floating solar installations are emerging as a fast-growing niche for steel mounting brackets, particularly in countries with limited land availability and abundant water bodies. These systems require specialized steel floats and mounting structures that can withstand water exposure, wave action, and corrosion. The steel used in floating solar must be heavily protected, often with hot-dip galvanizing or specialized coatings, to ensure a 25-year lifespan in aquatic environments. Through 2035, floating solar is expected to grow at a double-digit rate, driven by the co-location of solar with hydroelectric reservoirs, water treatment facilities, and aquaculture ponds.
Demand-side indicators include the number of floating solar projects in development, water body availability, and government support for innovative solar applications. Manufacturers are developing modular floating platforms that integrate steel brackets with high-density polyethylene floats, while also addressing challenges related to mooring and electrical safety. Current trend: Rapid growth from a small base, driven by land constraints and water conservation benefits.
Major trends: Co-location with hydroelectric dams to utilize existing grid infrastructure, Development of large-scale floating solar parks in Asia and Europe, Advancements in corrosion-resistant steel alloys and coatings, and Integration with water management and aquaculture systems.
Representative participants: Ciel & Terre, BayWa r.e, Trina Solar, JA Solar, and Sungrow.
Agrivoltaics, the co-location of solar panels with crop or livestock production, is an emerging segment that is gaining traction as a way to optimize land use and provide additional revenue streams for farmers. Steel mounting brackets in agrivoltaic systems are often elevated to allow sunlight to reach crops and to permit farming equipment to pass underneath. This requires taller structures and more robust steel components, increasing the steel intensity per megawatt compared to standard ground-mount systems.
Through 2035, agrivoltaics is expected to grow significantly, driven by policies that encourage dual-use of agricultural land and research demonstrating benefits such as reduced water evaporation and improved crop yields in certain climates. Demand-side indicators include agricultural land prices, government incentives for agrivoltaics, and farmer adoption rates. Manufacturers are developing adjustable tilt systems that can be optimized for both solar generation and crop growth, as well as structures that integrate with irrigation systems. Current trend: Emerging segment with high growth potential, combining solar generation with agriculture.
Major trends: Government incentives for dual-use solar and agriculture, Research on crop yields and microclimate effects under solar panels, Development of elevated mounting systems for machinery access, and Integration with precision agriculture and water management.
Representative participants: Nextracker, Array Technologies, GameChange Solar, Schletter Group, and Sun’Agri.

Suniva raises $835 million to drive 4.5 GW in new solar cell capacity – pv magazine Global

Suniva has announced the completion of an $835 million capital raise as it continues the buildout of a new 4.5 GW facility inside a 620,000 square-foot building currently under construction in Laurens County, South Carolina.
The infusion of capital includes both debt and equity financing, consisting of senior secured credit facilities provided by funds managed by Goldman Sachs Alternatives and I Squared Capital, a second lien credit facility provided by JBA Asset Management, and equity investments by Electron Capital Partners, Orion Infrastructure Capital (OIC), and Rubric Capital Management, among others. 
“As the only U.S.-owned solar cell manufacturer at commercial scale, we believe Suniva is uniquely well positioned in the market,” said Suniva CEO Tony Etnyre, in a statement. “We look forward to helping the United States and the Administration achieve its important goal of U.S. energy independence.”
The new facility will bring the company’s annual production capacity to 5.5 GW, including its existing 1 GW facility in Norcross, Georgia. In a 2023 announcement, Suniva said it would expand the Norcross facility to 3.5 GW in capacity, but the plan for the new South Carolina facility seems to have superseded the Georgia expansion 
Suniva says the new facility is expected to open in late 2027, with production ramping toward full capacity in 2028. The company expects the project to cost $600 million total, and the facility is expected to require 564 manufacturing workers when fully operational.
“With the addition of 564 jobs in advanced manufacturing and energy, Suniva’s commitment to this major expansion in the Palmetto State will create new opportunities for our workforce and help bolster energy independence in the United States,” said South Carolina Governor Henry McMaster. “This investment strengthens our commitment to innovative energy solutions, and we are proud of Suniva’s continued success in Laurens County.”
The expansion announcement comes at a time when the domestic solar manufacturing space is grappling with the effects of the recently-announced Section 232 trade action
The price floor and tariffs imposed by the Trump Administration have already caused the price of finished solar modules to jump up to levels not seen since the turmoil surrounding the 2023 anti-circumvention inquiry into companies operating in Southeast Asia.
The minimum import price for solar cells under the trade action is set at 22 cents per watt, with ad valorem tariffs of 15% added on top. The high price floor could make it more profitable for solar cell manufacturers like Suniva to produce cells domestically, and the company’s new 4.5 GW facility will position them to capitalize on trade policy as it stands.
In the announcement of its new facility, Suniva said the expansion is “de-risked by a domestic supply chain already in place and by long-term product offtake agreements with leading U.S. solar players for the majority of its planned future production.”

Home Energy Storage Competition Heats Up at IFA: Beyond Oversized Power Banks, AI + Modularization Emerges as New Industry Paradigm – 36Kr

On September 4, 2026, IFA 2026 (Berlin International Consumer Electronics Exhibition, Germany) officially opened. Themed “The Future is Now”, this year’s IFA gathers over 1900 exhibitors from 49 countries and regions, and is expected to attract 220,000 visitors from more than 140 countries.
The “Leitech IFA26 Reporting Team” dispatched by Leitech (ID: Leitech) is currently in Berlin, delivering timely, comprehensive and in-depth coverage of IFA 2026. As a pivotal exhibition in the global consumer electronics and home appliance sector, this year’s IFA features not only smartphones, TVs, smart home and AI products, but also home energy storage as a key display category. Brands including Anker, Dreame, Bluetti, Jackery, ALLPOWERS INC, and Tuestrong Power are no longer satisfied with producing a simple “electricity-storing battery”. They have begun to integrate photovoltaics, energy storage, household power consumption, dynamic electricity pricing and AI energy management into one unified system, transforming home energy storage from a single hardware category into a home energy access point.
If we trace the development trajectory of the home energy storage market over the past few years, a very clear product upgrading path can be observed: outdoor power station – photovoltaic power generation – balcony photovoltaic energy storage – home energy storage – home energy management.
Pursuing larger battery capacity is now a thing of the past. Today, enterprises are focusing on how to integrate photovoltaic power generation and energy storage into the home energy dispatch system, and reduce consumers’ electricity costs through AI algorithms.
It should be noted that pure photovoltaic power generation “depends on the weather”, and its power generation capacity is directly proportional to the light intensity. During consecutive rainy days, the value of traditional home energy storage will be greatly reduced. It is also a tricky problem to decide when to release the electricity stored in the energy storage device and how to minimize the overall electricity cost.

(Source: Shot by Leitech)
In response to this, Jackery has launched the Ark AI EMS system, which can automatically predict the household electricity demand in different time periods, as well as the photovoltaic power generation output and dynamic electricity price, so as to optimize the charging and discharging strategies.
Anker has taken similar steps. Its Solarbank Max AE111 can be used with photovoltaic panels, with a peak power generation of up to 10kW. MindBase, the home AI data hub, can monitor the presence of people in the house and the working status of home appliances in real time, to decide whether the Solarbank Max AE111 should enter the charging or discharging state.

(Source: Shot by Leitech)
Dreame’s AI home energy management platform LumeGret Orbit is similar to Jackery’s Ark AI EMS system, which can monitor photovoltaic power generation output, dynamic electricity prices and power consumption data in real time to optimize charging and discharging strategies.
The home energy storage system of Aoi Electronics is also integrated with the KARST electric vehicle charging solution, which can intelligently select time periods to charge new energy vehicles.
Considering factors such as the area of power generation panels and light intensity, photovoltaic power generation may not be enough to meet the daily household electricity demand. In addition, during long periods of poor light in the plum rain season, the power generation of photovoltaic panels will drop significantly. It is difficult to reduce electricity costs by relying solely on photovoltaic power to supply power for the whole household.
After the AI control system is added, the system will charge the battery during the off-peak electricity price period, and discharge power during the peak power consumption period to balance the electricity cost. This design makes home energy storage devices no longer dependent on photovoltaic panels, and realizes power regulation by relying on large-capacity batteries. Users can still enjoy the same electricity cost during peak price periods as they do in off-peak periods.

(Source: Shot by Leitech)
Leitech believes that home energy storage is undergoing a transformation of product logic from “storing electricity” to “managing electricity”. In the past, enterprises competed on battery capacity, but now the core of competition lies in how to realize the synergy of photovoltaics, energy storage, power grids, home appliances and new energy vehicles.
Especially after the introduction of AI, home energy storage no longer passively waits for photovoltaic power generation, but can actively decide when to charge and when to discharge by combining photovoltaic power generation output, dynamic electricity price and household electricity demand.
In other words, photovoltaics solve the problem of “where the electricity comes from”, energy storage solves the problem of “when to use the electricity”, and AI solves the problem of “how to use electricity at a lower cost”. This is also the key for home energy storage to truly enter the mass market. In the future, what users buy may no longer be a single battery, but a set of “smart energy stewards” that can continuously help households reduce energy costs.
While the industry is developing rapidly, home energy storage also has a threshold restricting its development — the purchase cost. A set of 10kWh energy storage equipment including an inverter costs at least 7,000 to 8,000 yuan, and even tens of thousands of yuan. Coupled with the cost of photovoltaic power generation equipment, the payback period takes at least several years. In addition to the purchase cost, battery degradation is also a hidden cost of home energy storage devices.
To solve this problem, Jackery SolarVault 3 Pro Max adopts a modular design, supporting capacity expansion from 2.52kWh to 15.12kWh.
Anker realizes modular design based on its PluginPower technology. Anker SOLIX Power Dock is equipped with 4*3600W sockets, supporting a maximum AC output of 4.8kW, photovoltaic power generation of 14.4kW, and an ultra-large battery capacity of 64.5kWh. Users can adjust its output power and battery capacity according to their own needs, which greatly reduces the upfront cost.

(Source: Shot by Leitech)
In addition, as the battery capacity continues to increase, the boundary between home energy storage and outdoor power stations is blurring. Take Jackery Explore 3000v2 as an example. This product has a capacity of 3.072kWh, an output power of 3600W, a peak power of up to 7200W, 8 output interfaces, and can be used with the SolarSaga photovoltaic charging panel. It is both a large-capacity outdoor power station and a home energy storage device.
The EcoFlow STREAM series exhibited by Ecoflow, based on the scalable modular design, can be expanded to a maximum capacity of 90kWh and an output power of 18kW. Its lithium iron phosphate battery has up to 10,000 cycles, and the product has a design life of up to 15 years.
Leitech believes that as modular design gradually becomes mainstream, the difference between home energy storage and outdoor power stations will be further narrowed. Enterprises including Anker, Jackery and Dreame can add modular design to all their outdoor power stations to support parallel output, making each outdoor power station a component of home energy storage.
When users need to use electricity outdoors, they can remove part of the unit from the home energy storage system and take it away. This design can not only greatly reduce the cost for consumers to purchase home energy storage devices and outdoor power stations, but also is expected to attract home energy storage device owners to buy multi-scenario outdoor power stations that can be used both at home and outdoors, and attract outdoor power station users to expand their home energy storage systems, which kills two birds with one stone.

(Source: Shot by Leitech)
Judging from the home energy storage products exhibited at IFA 2026, modular design is becoming an important path for the industry to lower the consumption threshold and expand usage scenarios. Compared with purchasing a large-capacity energy storage system at one time, users can gradually increase the battery capacity according to their household electricity needs, thus reducing the upfront investment and extending the life cycle of the device at the same time.
What is more noteworthy is that modular design is breaking the product boundary between home energy storage and outdoor power stations. When batteries, inverters and energy storage hosts can be flexibly combined, an outdoor power station can not only work independently, but also become a “battery” of the home energy storage system.
In Leitech’s view, this may have greater industrial value than simply pursuing larger capacity. It not only enables consumers to realize “one set of equipment for multiple scenarios”, but also provides enterprises with the opportunity to expand their user base from outdoor power station users to home energy storage users. In the future, home energy storage may no longer be a set of fixedly installed equipment, but a group of energy modules that can be freely combined, expanded on demand, and switched freely between household and outdoor scenarios.
Judging from the products exhibited at IFA 2026, home energy storage is entering a new stage of development. In the past, the core competition of the industry focused on battery capacity, output power and cycle life, and enterprises hoped to use larger batteries to meet more household electricity needs.
Nowadays, as photovoltaics, dynamic electricity pricing, new energy vehicle charging and AI energy management are gradually integrated into one unified system, the competition logic of home energy storage is undergoing fundamental changes.
In this development process, AI will become the “decision-making layer” of the home energy system, enabling energy storage devices to actively participate in home energy dispatch by predicting power generation, power consumption and electricity prices; modular design will serve as the important “hardware foundation”, allowing consumers to gradually expand capacity according to their needs, and promoting the disappearance of the boundary between home energy storage and outdoor power stations.

(Source: Shot by Leitech)
Looking further, home energy storage may also become a new connection node between smart homes and new energy vehicles. Photovoltaics is responsible for power generation, batteries are responsible for energy storage, AI is responsible for dispatch, and home appliances and new energy vehicles become the energy consumption end. When these devices form a closed loop, the role of home energy storage will evolve from a single device to the “hub” of the entire home energy system.
Leitech believes that the real signal released by IFA 2026 is not how many new home energy storage products have been launched, but that this industry is shifting from “selling equipment” to “selling systems”, and from one-time hardware sales to continuous energy services. In the future, what consumers buy may no longer be a fixedly installed battery, but a smart energy system that can automatically generate, store, use and regulate electricity, and continuously help households reduce energy costs.
This is perhaps the most anticipated next transformation after home energy storage truly enters the mass market.

The decision could help companies move forward with rooftop solar projects by removing approval confusion.

Businesses in Andhra Pradesh, India, may have an easier time putting rooftop solar to work behind their electricity meters, potentially cutting energy costs without some of the approval hurdles that had been slowing projects down.
A new decision from the state regulator clarified how captive solar installations can be deployed while still requiring utilities to stay informed for grid safety and planning.
According to SolarQuarter, the Andhra Pradesh Electricity Regulatory Commission has released practice directions for rooftop solar panels installed on the customer’s side of the meter and used to power that customer’s own operations.
The action came after stakeholders served by the Eastern Power Distribution Company of Andhra Pradesh raised concerns about administrative delays and synchronization-related approvals for solar capacity installed on the customer side of existing meters. In effect, businesses trying to use solar generation within their own premises had been facing procedural slowdowns.
Under the clarification, consumers may attach captive solar systems to their own internal bus bars without seeking prior consent, feasibility clearance, or line approval from distribution companies. The commission said Section 9(1) of the Electricity Act 2003 puts everything on the customer’s side of the meter under that customer’s control.
As a result, customers can configure those internal arrangements to suit their engineering needs, including choosing voltage levels and using multiple inverter connections, so long as applicable safety requirements are followed.

Behind-the-meter solar is particularly important for industrial and commercial users because it can reduce reliance on expensive grid electricity during daytime operations. By generating power on-site, businesses may be able to lower operating costs, improve energy resilience, and cut pollution associated with conventional power generation.
The order also settles questions about how these projects are treated commercially, not just technically. According to SolarQuarter, cross subsidy surcharges and additional surcharges do not apply to behind-the-meter rooftop solar systems. It said that exemption extends to projects built through third-party investment or other external financing arrangements.
Avoiding those surcharges could be a major factor for consumers. At the same time, SolarQuarter reported that systems must be operated during synchronization so that no power is exported into the main grid.
Consumers still remain liable for any regulated capacity charges set by the commission, while the utility may request reasonable service charges through standard retail tariff proceedings.
The regulator’s directions look to balance two priorities: making clean energy adoption easier and preserving orderly grid operations. Utilities no longer have to sign off on the design of a consumer’s private behind-the-meter setup, but the relevant distributor must still be informed before a solar system is interconnected or islanded.
According to SolarQuarter, consumers are required to submit technical details, such as their system’s size and a diagram of how it’s wired, to help utilities with demand forecasting and grid management.
Connecting to the grid first and notifying the utility later can trigger penalties under Sections 142 and 146 of the Electricity Act 2003.
On-site rooftop solar for self-use has become easier to pursue in Andhra Pradesh, especially for businesses looking to control electricity costs without paying open-access-style surcharges on power generated within their own premises.
If the decision is implemented smoothly, it could help companies move forward with rooftop solar projects by removing approval confusion and confirming surcharge exemptions. That may support wider use of distributed renewable energy across Andhra Pradesh while giving businesses more control over their electricity bills.
Andhra Pradesh isn’t the only place trying to make on-site solar easier to use. Officials in New Hampshire, New York, and Colorado are exploring similar ways to expand behind-the-meter access without long approval processes or added hurdles.
• In New Hampshire, lawmakers adopted plug-in solar without utility approval or extra fees.
• In New York, officials could allow residents to install balcony solar without utility approval.
• In Colorado, officials are removing barriers and red tape for plug-in solar access.

IEA Sees Major Rooftop Solar Potential in Türkiye – caspianpost.com

Source: Anadolu Agency

Türkiye could add around 120 gigawatts (GW) of solar photovoltaic (PV) capacity through rooftop installations, which would be enough to meet 45% of the country’s electricity demand if fully developed, according to the International Energy Agency (IEA).
The expansion of rooftop solar could help decentralize electricity generation, reduce reliance on centralized energy systems and increase the share of solar power in Türkiye’s electricity mix, the IEA said in its “Türkiye Energy Policy Review,” The Caspian Post reports, citing Anadolu Agency.
The model could also reduce dependence on energy generation subsidies while allowing consumers to produce electricity at more affordable costs.
Türkiye’s three most populous cities – Istanbul in the northwest, Ankara in central Türkiye and Izmir on the Aegean coast – also have the country’s highest rooftop solar potential.
According to the report, expanding rooftop solar is important not only for increasing renewable energy capacity but also for strengthening energy security.
Rooftop solar systems could contribute to a more resilient and decentralized energy system by helping maintain electricity supply, at least to some extent, when centralized energy systems are disrupted by natural disasters such as earthquakes.
Despite the advantages of rooftop solar PV compared with large-scale solar power plants, its deployment continues to face regulatory and practical challenges.
In 2019, Türkiye introduced a monthly net metering system that allows residential solar users to sell excess electricity at consumer rates.
However, the length of the installation process remains one of the factors limiting the expansion of rooftop solar. The process, which requires approval from multiple authorities between application and installation, can take up to 27 weeks.
Türkiye is implementing a series of reforms and investments to achieve its 2035 wind and solar energy targets.
Legal amendments introduced on July 24, 2025, paved the way for reducing the permitting process for wind and solar power plants from approximately 48 months to 18 months.
Further improvements to application procedures, along with requirements for rooftop solar systems on new and public buildings, could help Türkiye advance its energy and self-sufficiency targets while enabling consumers to generate electricity at lower costs.
Solar photovoltaic (PV) technology has benefited most from Türkiye’s unlicensed electricity generation regime, which has driven a rapid increase in rooftop solar installations, particularly in the residential and agricultural sectors.
Solar PV accounted for 97% of the country’s unlicensed electricity generation capacity, or approximately 23 GW, at the end of 2025.
According to the report, strengthening distributed energy infrastructure will be important to further expand this capacity, while smart meters are expected to support the development of small-scale, distributed and renewable energy infrastructure.
A key objective of the roadmap is to add 35 GW of flexible resources to the electricity system.
Of this total, 10 GW will come from rooftop solar combined with storage, 10 GW from large-scale energy storage, 5 GW from grid management and 10 GW from demand-side management.
With the expansion of distributed generation, the deployment of smart meters and increased energy storage capacity, rooftop solar is expected to play a greater role in Türkiye’s electricity system, both by increasing the share of renewable energy and strengthening energy security.

A solar cell bent 5,000 times around a curve tighter than a thumb kept 91 percent of what it started with, while the flexible tandem inside it reached 33.6 percent certified efficiency on a silicon layer thin enough to roll – Energies Media

Energies Media
The jig takes both ends of the strip, folds it toward itself, holds it, and lets go.
Then it does it again.
It ran that way for days, and the film in the clamps looks like nothing at all. Not a panel, not glass, barely a component.
Yet the interesting part of the test is not whether the thing survives the folding.
It is why folding should cost it anything in the first place.
Two semiconductors are sitting on top of each other in there.
The upper one, a perovskite, takes the high energy blue and green light. The one below it, ordinary crystalline silicon, takes the red and infrared that slips through.
Between them sits a layer most people never hear about, a few atoms of oxide whose only job is to let electrons arriving from above meet holes arriving from below and cancel out cleanly.
That seam is the whole problem.
When the sandwich bends, the two materials do not stretch by the same amount. They want to slide against each other, and where they slide, gaps open at the boundary.
Carriers fall into those gaps. Voltage drops. The cell does not crack, it just quietly stops adding up.
So the seam is where the work went. The team built that middle layer out of indium oxide co doped with cerium and hydrogen, laid down by reactive plasma, which grips both faces tightly enough to take the movement.
Voltage is the giveaway, and it came out at 2.015 volts open circuit, a record for a bendable device and level with rigid cells of the same design.
A single material has a ceiling.
Tune it to one slice of the spectrum and it wastes the rest, which caps a one junction cell at roughly 33.7 percent in theory.
Stacking two materials with different appetites is the only way past that line, and it is why every efficiency record of the last few years has been a stack.
The bending is a separate trick entirely.
An ordinary solar wafer runs 150 to 180 micrometers thick and snaps rather than bends.
Thin it down far enough and silicon becomes flexible, and a comparable flexible tandem announced weeks earlier was built on a wafer of 60 micrometers, thinner than a lot of human hair.
The result was published in Nature on 10 November 2025 by a group at Soochow University in Suzhou with collaborators in Saudi Arabia.
The efficiency is 33.6 percent certified, not a self reported bench figure.
After 5,000 bending cycles at a radius of about 0.69 inches, roughly the curve of a thumb, the cell held 91 percent of where it started.
Not 97. The 97 percent figure belongs to a different flexible tandem, bent 43,000 times around a gentler curve.
It also kept 90 percent after 1,000 hours of damp heat, and ran past 2,000 hours of continuous illumination before dropping to 80 percent of its initial output.
The comparison everyone reaches for is the rigid record, and that number moved.
It was 34.85 percent, certified by the American national laboratory in the spring of 2025, which puts the flexible cell 1.3 points behind.
But a European test institute certified 35.5 percent in July of this year, so the real distance is closer to 1.9 points, as the paper and the record announcements together make clear, and the newer figure came with no active area disclosed at all.
Then there is the jump from a fingernail sized coupon to a factory. Perovskite is grown from liquid chemistry, manageable at that size and stubborn across a full sheet, where pinholes and thickness gradients eat the yield.
The commercial reference point makes that concrete. The first tandem modules sold anywhere shipped in September 2024 at 24.5 percent, about nine points below this cell, and they are rigid glass.
Verification is its own story, as a Finnish battery cell showed when independent tests refused to agree, and the road from a laboratory win to a product is the same one an iron catalyst is still walking.
Not rooftops. Glass is cheap, flat and already there.
What changes is the argument.
Flexibility used to mean accepting a serious efficiency penalty, and that penalty has now shrunk to almost nothing in the laboratory.
That moves the question from whether it can be done to whether it can be made in volume, which is a more tractable kind of problem.
The uses that follow are the awkward ones. Curved building surfaces, vehicle skins, equipment carried into places with no grid, all of them shapes a glass panel simply cannot take.

What is balcony solar, and is it worth it? Expert explains – Virginia Tech News

9 Sep 2026
Solar energy can take many forms, but one of the newest in the United States is balcony solar. Already legal in Maryland and Virginia, with a bill pending in D.C., these compact units offer Mid-Atlantic renters and homeowners an inexpensive way to diversify their energy options, reduce stress on the grid, and save on their monthly bills.
Virginia Tech energy expert Saifur Rahman explains that, “Unlike more traditional rooftop solar systems that have existed for decades, the DC-AC inverter that comes with the panel connects directly to the household electrical outlet. It has electronic controls that allow electricity to flow to the house or apartment without any additional hardware.” 
Because these systems are much smaller than full-house systems, they won’t replace your full energy load. Rahman says how much energy you can generate depends on how much space you have and the size of the panel you’re using. A typical 540-watt solar panel measures 90” x 68”. 
“Two south-facing 540-watt panels will produce about 125 kWh of electricity in a clear, sunny month — a bit more in summer and less in winter,” says Rahman. “This will save the homeowner about $12 to $15 per month in Virginia.”
For those concerned about the broader increase in energy use across the region, adding balcony solar will also alleviate a bit of stress from the overall grid. But Rahman cautions that for optimal results, you do need a southern exposure — “if the balcony happens to face north, the above calculations will not hold.”
About Rahman
Saifur Rahman is the director of the Advanced Research Institute at Virginia Tech, where he is the Joseph Loring Professor in the Bradley Department of Electrical and Computer Engineering. An internationally known researcher in the areas of electrical power, renewable energy, and smart grid, Rahman is the former president and CEO of the Institute of Electrical and Electronics Engineers.

Rocket Lab Jumps as ARK Invest Boosts Stake and New Solar Cell Debuts – finance.biggo.com

Rocket Lab USA (RKLB) extended its rally in premarket trading Wednesday after Cathie Wood’s ARK Invest disclosed another purchase of the space company’s shares and Rocket Lab unveiled a new solar cell technology that eliminates a critical material from its design.
The stock climbed more than 3% before the opening bell, adding to a 2.51% gain during Tuesday’s regular session. The advance came even as Nasdaq futures pointed 0.46% lower and S&P 500 futures slipped 0.36%.
The dual catalysts gave investors two company-specific reasons to buy. On the product side, Rocket Lab introduced IMM Apex, a high-efficiency solar cell for space applications that the company says delivers 31.5% beginning-of-life conversion efficiency while cutting mass by 40% compared with earlier models. The design removes germanium substrates, a component that has been standard in multi-junction solar cells for more than three decades and has faced rising costs and supply constraints.
Brad Clevenger, president of Rocket Lab USA, said the cell “delivers exceptional performance while addressing real-world challenges like rising material costs and supply chain constraints.” He added that the product is designed to “more cost-effectively power the most ambitious missions without compromising performance.”
The technology functions as a direct drop-in replacement for existing satellite solar cells, meaning customers can adopt it without significant hardware modifications. Rocket Lab said the cell is available immediately, with manufacturing capacity in the multi-100-kilowatt range. The underlying technology previously powered NASA’s Ingenuity Mars Helicopter and has operated in orbit for more than a decade. Rocket Lab’s solar products currently support more than 1,100 satellites, including the James Webb Space Telescope and NASA’s Artemis missions.
On the ownership side, the ARK Space Exploration & Innovation ETF (ARKX) bought 2,341 Rocket Lab shares on Tuesday, a transaction worth roughly $154,000 based on the closing price. That follows a substantially larger buying spree: ARK acquired 705,102 shares across three exchange-traded funds over two trading days earlier this month, worth about $44.4 million. The purchases were made through ARKX, the ARK Innovation ETF (ARKK), and the ARK Autonomous Technology & Robotics ETF (ARKQ).
Rocket Lab now carries a 5.70% weighting in ARKX, along with a 4.07% position in ARKQ and a 4.04% stake in the Defiance Space and Connective Tech ETF (UFOX). Because the stock holds sizable weightings in these funds, ETF inflows and outflows can contribute to meaningful buying or selling pressure.
Operational Momentum
Beyond the immediate catalysts, Rocket Lab has been building operational credibility. The company completed its 94th Electron mission last week, deploying a StriX Earth-imaging satellite for Japanese radar company Synspective. It was Rocket Lab’s 15th launch of 2026 and its 11th dedicated mission for Synspective, with a 100% success rate across those flights. Another 16 Synspective missions are booked through 2030.
Rocket Lab also passed the preliminary design review for 18 satellites it is building for the U.S. Space Development Agency’s Tracking Layer Tranche 3 constellation, a milestone the company called a “big step forward” toward delivering missile-warning and defense capabilities for the United States and its allies.
Financially, the company reported $234.1 million in second-quarter revenue, a 62% year-over-year expansion. Its contract backlog reached a record $2.36 billion. Rocket Lab’s market capitalization stands at approximately $39.4 billion.
Wall Street’s View
Analysts remain broadly constructive on the stock. Rocket Lab carries a Strong Buy consensus rating, with 13 Buy recommendations and four Hold ratings issued over the past three months. The average price target sits at $108.88, implying roughly 65% upside from current levels.
Recent analyst actions include Bank of America Securities maintaining a Buy rating while trimming its price target to $110 on Aug. 31. Citizens held a Market Outperform rating with a $130 forecast on Aug. 11, while Cantor Fitzgerald maintained an Overweight rating and raised its target to $122 the same day.
Technical Picture
Despite the recent bounce, Rocket Lab remains below its major moving averages. The stock trades 4.9% below its 20-day simple moving average and 9.4% below its 50-day SMA. It sits 25.1% below the 100-day SMA and 15.1% below the 200-day SMA. The 20-day SMA remains below the 50-day SMA, and the 50-day crossed below the 200-day in August, forming a “death cross” that points to pressure on the longer-term trend.
Momentum indicators also suggest caution. The MACD sits below its signal line with a negative histogram, indicating buying momentum has not fully recovered. Rocket Lab faces resistance near $78.50, with support around $58.50.
The stock has gained roughly 38% over the trailing twelve months but remains well below its 52-week high of $151, reflecting the extent of the pullback since May. The 52-week range spans from $37.57 to $151, and the relative strength index reading sits at 40.94.
On Stocktwits, retail sentiment for RKLB slipped to “bearish” from “neutral” levels a week ago, even as 24-hour message volumes jumped 369%. One bullish user wrote, “$RKLB bought 500 shares of this back in 2024 when it was at $9 and sold in the $20’s and I regretted it. I repurchased 1k shares last week at $59 and ain’t selling till we are at $150.”

After a rooftop solar system that had kept power costs nearly at zero seemed to drop to about half its usual output, a California homeowner ended up facing a startling $400 Edison bill.
The complaint, shared in a Reddit thread on r/solar, resonated because it reflects one of the most frustrating scenarios for solar owners: investing in panels to cut energy costs, only to be blindsided when production drops and no one can immediately explain why.
According to the homeowner, the house has a 36-panel setup that had been generating about 33 kilowatt-hours per day.
They said July production fell from 800 kilowatt-hours last year to 398 this year, while bills that had been less than $5 during the same period a year ago rose to $200 or more, with Edison forecasting another $400 charge.

To get started, just answer a few questions about your home — no phone number required. Within a day or two, EnergySage will email you the best options for your needs, and their expert advisers can help you compare quotes and pick a winner.
Commenters pointed to a likely issue somewhere in the solar panel system itself.
One commenter wrote, “It’s possible you’ve lost a string. Maybe one of the breakers has tripped.”
Others said the homeowner should use the Enphase monitoring app to review output panel by panel, which could show whether the drop is tied to just a few weak panels or a larger portion of the array going offline.
Going solar remains one of the best ways to save money on home energy, especially when a system is installed and monitored correctly. Homeowners considering solar panels can explore EnergySage to get free solar installation estimates and compare quotes.
FROM OUR PARTNER
Want to go solar but not sure who to trust? EnergySage has your back with free and transparent quotes from fully vetted providers that can help you save as much as $10k on installation.
To get started, just answer a few questions about your home — no phone number required. Within a day or two, EnergySage will email you the best local options for your needs, and their expert advisers can help you compare quotes and pick a winner.
The homeowner said, “Nothing has changed in my home. AC set same as last year, I still work from home. Legit nothing has changed.”
The installer first indicated that the Enphase app did not appear to show a problem, the homeowner said, but later checks showed the system had generated 25.3 kilowatt-hours that day and that two panels were not working.
Commenters replied that losing just two panels would probably not be enough to explain a 50% decline in production.
One commenter also noted that utility charges can rise for reasons beyond solar output alone, since rates and billing formulas may change. They suggested comparing the home’s electricity pulled from the grid and the power sent back out by the solar system against the monitoring data.
💡Go deep on the latest news and trends shaping the residential solar landscape
Commenters said a good place to begin is the monitoring platform, using it to compare production with earlier months or with the same time of year in the past.
The array view may help pinpoint whether the issue involves a failed panel, a lost string, a tripped breaker, a blown protective device, or even wire damage caused by animals.
Before paying for a service appointment, several commenters urged the homeowner to contact Enphase directly.
One wrote, “CALL ENPHASE!” and said the company may be able to remotely access the Envoy, update firmware, and sort out whether the problem is tied to communications, inverters, or other hardware that might need replacement.
For anyone still shopping for solar, EnergySage’s free services can help reduce the odds of expensive surprises by making it easier to compare installers and equipment. With EnergySage’s help, the average person can save up to $10,000 on solar purchases and installations.
Readers can also use EnergySage’s solar map, which shows the average cost of a home solar panel system on a state-by-state level, along with details on solar panel incentives for each state, helping homeowners get the best price for rooftop solar panels and access available incentives.
Adding battery storage to a solar setup is also one of the best ways to protect your home during outages, save money on energy, and go off-grid. Homeowners who want to compare options can explore EnergySage for information about home battery storage, including competitive installation estimates.
A surprise electric bill can catch even solar households off guard, and one monthly statement does not always make clear what went wrong. These examples echo the California homeowner’s experience.
• A new homeowner learned their rooftop solar offered little relief when their first bill hit $420.
• In South Carolina, app data showed exports while a $150 bill claimed 900 kilowatt-hours came from the grid.
• In El Paso, Texas, a rooftop solar fee pushed one utility bill from $30 to $117.
• On the other hand, in Florida, one homeowner turned an $800 power bill into a $300 credit.
Solar savings can depend on more than how many panels are on the roof. Comparing utility formulas, installer work, and app data side by side can make it easier to figure out what actually changed.

Metalogika intends to establish solar cell manufacturing in Indonesia with Midsummer equipment and know-how – renewableenergymagazine.com

PT Metalogika intends to establish a thin film flexible solar panel production facility in Indonesia with an initial production capacity of 20 MW per year, with potential further expansion toward 200 MW annually, for the sale of solar panels in the Indonesian market and abroad.
Midsummer will supply the manufacturing equipment and related services for the establishment and operations of the solar cell factory to the new joint venture and also assume a minority ownership in the Indonesian joint venture.
The currently contemplated equipment scope consists of Midsummer’s proprietary DUO system for the production of thin film solar cells, other manufacturing equipment and services sufficient for a 20 MW per year solar cell factory.
The equipment procurement will be entered into by the Indonesian joint venture following its incorporation and satisfaction of the agreed conditions. This structure is intended, among other things, to allow the project to establish the appropriate Indonesian investment and import framework before manufacturing equipment is imported.
The initial 20 MW facility is intended as the first phase of a broader industrial roadmap. Following successful commissioning and operation, the parties intend to evaluate expansion toward 200 MW of annual production capacity, with longer-term potential for further expansion toward gigawatt scale, subject to market demand, financing, operational performance and future investment decisions.
The strategic ambition is to develop Indonesia into an important manufacturing node within Midsummer’s geographically distributed production ecosystem, initially serving Indonesia and progressively supporting opportunities in Southeast Asia and other markets.
“Our ambition is to build a long-term industrial partnership in Indonesia, combining Midsummer’s technology and manufacturing experience with Metalogika’s Indonesian industrial capabilities” said Eric Jaremalm, CEO, Midsummer. “We intend to start with a clearly defined 20 MW industrial project, while creating the foundation from which the partnership can scale significantly as the market develops. I see this as another validation of Midsummer’s technology and of our strategy to offer partners not only equipment and solar products, but access to a complete industrial manufacturing platform — technology, know-how, engineering, training, procurement and long-term production support.”
The parties will now proceed with incorporation of the joint venture, finalisation of the investment and governance structure, applicable Indonesian approvals and incentives, project financing and definitive equipment and technology agreements.
Indonesia has a population of approximately 285 million. It is the largest economy in Southeast Asia with a GDP exceeding $1.4 trillion and growing at 4-5 percent per year. Indonesia’s energy mix is heavily reliant on fossil fuels, with renewable energy sources making up approx. 18 percent of the power generation mix. Located directly on the equator, Indonesia has massive solar energy potential, backed by a very high daily solar radiation average and government ambitions for a rapid scale-up of solar energy production.
“Our objective is to establish advanced solar manufacturing capability in Indonesia and progressively build a locally anchored industrial ecosystem around it” added Firrisky Nurtomo, President Director, PT Metalogika Rekayasa Sistem. “One of the nearest aim is to support the country’s focus to strengthen energy independence and security. Midsummer brings not only manufacturing technology but experience, know-how and access to a wider international production ecosystem.”

Beyond the inverter: GoodWe’s path to an intelligent prosumer energy ecosystem – pv magazine Global

As solar markets mature, storage, flexible loads and AI-driven energy management are changing what customers expect from an energy system — and how GoodWe defines its role within it.
Europe’s residential energy market is entering a new phase. For much of the past decade, the central question for homeowners was whether to install rooftop solar. Increasingly, the question is how to use that solar more intelligently — combining generation with batteries, electric vehicles, heat pumps, flexible tariffs and automated energy management.
That shift is reshaping the competitive landscape for companies that grew up around the solar inverter. For GoodWe, it also coincides with a transformation of its own. The company’s 2026 interim report showed that overseas markets accounted for 72.72% of first-half revenue, while energy storage battery sales reached approximately 2.4 GWh. During TÜV Rheinland’s “All Quality Matters” event, GoodWe Vice President Wang Yinge said storage inverters and batteries now make up the large majority of the company’s overseas business.
The change is not simply geographic. It is structural.
GoodWe describes this direction through its “Generation-Grid-Load-Storage-Intelligence” strategy: a shift from supplying individual pieces of power electronics toward connecting distributed generation, storage and controllable loads through an increasingly intelligent energy management layer. The objective is not to assemble the longest possible product list, but to make these assets operate as one system around the needs of the energy prosumer.
Storage as the hardware anchor
Storage has become the physical anchor of this transition.
Europe illustrates why. The continent installed 36 GWh of new battery storage in 2025, taking cumulative operational capacity above 100 GWh for the first time, according to SolarPower Europe. Residential storage remains a major part of the installed fleet, and the association expects residential additions to regain momentum in 2026, supported by the growing availability of dynamic tariffs, lower remuneration for exported solar electricity and rising consumer interest in energy self-sufficiency.
For homeowners, however, battery economics are only part of the equation. Installation labor, system complexity, noise, reliability and after-sales service increasingly determine whether a system works in practice.
That thinking has influenced GoodWe’s ESA residential storage platform. Built around what the company calls its “4S” principles — Silent, Secure, Smart and Simple — the system integrates inverter, battery and backup functionality into an all-in-one architecture. Wang said installation simplicity is particularly important in Australia and Western Europe, where qualified installers are expensive and often in short supply.
GoodWe has therefore placed considerable emphasis on reducing installation time and complexity. The ESA platform has been designed around quick connections, integrated components and low-noise operation, while its software layer connects storage with the broader household energy ecosystem.
This point goes beyond a single product. As hardware becomes increasingly integrated and battery technologies converge, differentiation gradually shifts from individual specifications toward the performance of the complete home energy system.
Intelligence as the connective layer
If storage is becoming the physical center of that system, intelligence is becoming its economic center.
A battery can transfer energy on time, but its value increasingly depends on knowing when to charge, when to discharge, when to consume solar energy directly and when to buy electricity from — or export it to — the grid. These decisions become more complex as electricity prices become more dynamic and households add flexible loads such as EVs and heat pumps.
GoodWe’s SEMS+ platform is designed to provide that connective layer. It connects inverters, batteries, EV chargers and heat pumps while using AI-supported control to optimize household energy flows. The platform supports fixed tariffs, time-of-use tariffs and, for selected markets and compatible devices, dynamic electricity pricing.
This capability is becoming increasingly relevant in Europe. The European Commission notes that dynamic electricity contracts can allow consumers to lower their bills by shifting demand in response to changing wholesale prices. Households equipped with flexible assets such as EVs, heat pumps and batteries are particularly well positioned to respond — although doing so effectively requires smart metering and either active management or automation.
For GoodWe, automation is therefore not simply a digital add-on. It is what can turn a collection of energy devices into an operating system.
“In Europe, if everything has to be managed manually, it simply cannot be done,” Wang said. “The system needs to know when to charge, when to discharge, when to use solar power and when to use electricity from the grid.”
The strategic implication is significant: the value of a battery will increasingly be determined not only by how much energy it can store, but by how intelligently that flexibility can be used.
One strategy, different markets
An integrated strategy does not mean selling the same system everywhere.
GoodWe’s international expansion has produced two contrasting market templates. In Australia and much of Western Europe, relatively high labor costs and limited installer capacity favor high-voltage, integrated systems that are fast to install, quiet and simple to commission. In markets such as Pakistan and parts of Asia, Africa and Latin America, weaker grids, frequent outages and greater price sensitivity create a stronger case for lower-voltage, modular systems focused on backup capability and affordability.
Europe itself is not a homogeneous market. Wang pointed to countries such as Germany, the United Kingdom, France and the Netherlands, where installer productivity, system simplicity and reliability are important purchasing considerations. In parts of Central and Eastern Europe, by contrast, affordability, backup power and energy security can carry greater weight.
This makes localization more than a sales exercise. GoodWe has established subsidiaries, local warehouses and local service teams across key overseas markets while adapting product architectures, certifications and service models to regional requirements. The company is also strengthening carbon management, hazardous-substance control and supply-chain traceability as sustainability and compliance requirements become more important.
The logic is straightforward: global scale increasingly depends on local fit.
From selling equipment to creating prosumer value
GoodWe’s strategy goes beyond hardware integration.
Wang describes the underlying customer as an energy prosumer — someone who does not merely consume electricity, but can also generate, store, shift and potentially sell it. Viewed from this perspective, “Generation-Grid-Load-Storage-Intelligence” becomes less a description of GoodWe’s product portfolio than a value chain.
Solar PV and BIPV provide generation. Inverter transfers power to grid or storage. Batteries provide flexibility. EV chargers and heat pumps add controllable loads. SEMS+ connects these assets and responds to tariffs, forecasts and grid conditions. The outcome is measured not by the number of devices installed, but by lower energy costs, higher self-consumption, greater resilience and, where market mechanisms allow it, additional value from flexibility.
GoodWe’s Smart Energy WE Platform already manages more than 10 GW of distributed PV, storage and charging resources in China, supporting applications including virtual power plant dispatch and intelligent energy management.
But Wang sees a longer-term destination beyond monitoring and optimization: energy operation services.
In this model, an energy service provider could eventually manage a customer’s distributed energy assets, optimize power purchases and consumption, and share part of the additional value created with the customer. The underlying principle, Wang said, is simple: GoodWe can only create business value when it first creates measurable value for the energy user.
This model will develop differently across markets, and GoodWe does not expect every element of the strategy to be deployed everywhere at once. In one market, the immediate opportunity may simply be adding storage to existing solar. In another, it may be connecting batteries to dynamic tariffs. Elsewhere, distributed assets could eventually be aggregated into virtual power plants and participate more actively in electricity markets.
The inverter may have been where GoodWe’s story began, but it is unlikely to define where the company is heading. As distributed energy becomes more interactive, more market-driven and increasingly intelligent, the next competitive frontier will be less about individual devices and more about how effectively generation, storage and flexible loads can work together.
For GoodWe, its Generation-Grid-Load-Storage-Intelligence strategy is ultimately an attempt to answer that question — by moving from supplying energy hardware toward orchestrating energy around the needs of the prosumer.

Credit: HIGHER EDUCATION PRESS
Perovskite materials have emerged as promising candidates for next-generation solar cells, light-emitting diodes, and photodetectors because of their remarkable optical and electronic properties. However, the widespread use of lead-containing perovskites has raised environmental and sustainability concerns. Lead-free halide double perovskites offer an attractive alternative, but their performance is strongly influenced by complex structural, electronic, and defect-related factors.
 
In this review, Soo-Yeon Yang and Hyojung Kim examine recent advances in 2D and quasi-2D LFHDPs, focusing on how structural design translates into material properties and ultimately device performance. The review goes beyond a conventional classification of perovskite compositions by establishing a structure-property-device performance framework.
 
Particular attention is given to layered architectures, including Ruddlesden–Popper, Dion–Jacobson, alternating-cation with (111)-oriented structures. The authors discuss how organic spacer cations, crystal orientation, dimensionality, composition, and interfaces influence bandgap, exciton behavior, charge transport, defects, and stability. Quantitative comparisons of optical and electronic properties and representative device performances are also provided to facilitate direct comparison among different LFHDP systems.
 
The review further highlights the growing potential of layered LFHDPs in photovoltaic, light-emitting, and photodetection applications. For LEDs, special emphasis is placed on exciton-related emission, self-trapped-exciton and dopant-mediated luminescence, photoluminescence quantum yield, and device architecture. Strategies including spacer engineering, compositional tuning, defect passivation, and interface engineering are discussed as routes toward improved device performance.
 
Despite rapid progress, several challenges remain, including wide or indirect bandgaps, strong exciton binding, limited carrier mobility, defect formation, operational stability, and scalable manufacturing. The review therefore identifies emerging opportunities in AI-assisted materials discovery, high-throughput computational screening, machine learning, green synthesis, multidimensional heterostructures, and industrial-scale processing.
 
By linking structure → properties → device performance → future engineering strategies, this review provides a practical roadmap for the development of sustainable, high-performance lead-free perovskite optoelectronics. The work entitled “Structure-property relationships in 2D/quasi-2D lead-free halide double perovskites for optoelectronic devices” was published in Frontiers of Optoelectronics (published on Sept. 1, 2026) .

Birds & the poop on solar panels: does solar harm avian biodiversity? – Animals 24-7

Animals 24-7
News on dogs, cats, horses, wildlife, zoonoses, & nature
By Leave a Comment

NANJING, China;  HONG KONG;  SINGAPORE––”China’s Solar Expansion Policy Reduces Bird Diversity,”  a study led by a Chinese professor with no background in either ornithology or avian ecology,  but with a history of doing research linked to the coal industry,  rattled solar panels around the world after appearing in the prestigious peer-reviewed journal Science on August 20,  2026.
The findings were immediately amplified globally,  especially by media supportive of coal use.  Coal still supplies about 35% of the energy used to produce electricity worldwide,  but has rapidly lost market share to solar and wind,  and is fighting competition from solar and wind on every inhabited continent.

Solar and wind together produced less than 2% of the world’s electricity in 2000,  but now produce 13%.
The decline in Chinese use of coal has been even steeper.  Coal produced 60% of the Chinese electricity supply in 2011,  but only 48% in 2025.
Yet “A lie can travel halfway around the world while the truth is putting on its shoes,”  as Jonathan Swift observed circa 1710,  well before the invention of electronic media.
So can a study that doesn’t hold up.
Within days a flock of critics led by the China Ornithological Society were picking apart “China’s Solar Expansion Policy Reduces Bird Diversity” like vultures on a roadkill.
Protested lead study author Huiming Zhang,  of the Nanjing University of Information Science & Technology,  to Agence France Presse,  “The main message is not to slow the renewable energy transition,  but to make solar development more ecologically informed.”

Perhaps China’s most prominent energy economist,  Huiming Zhang has led many studies and published many papers pertaining to both coal use to generate electricity and use of solar and wind energy.  But a look at his bibliography suggests a tilt toward continuing to develop Chinese coal fields,  currently producing about half of the total global coal supply,  even as China also leads the world in solar development.
“China’s Solar Expansion Policy Reduces Bird Diversity,”  explained the abstract,  “examined the effect of policies promoting solar photovoltaics on local avian biodiversity,”  using data gathered from 2,344 counties in China between 2014 and 2023.
“Policies that favored photovoltaic expansion led to reductions in bird diversity, disproportionately affecting wealthier and non-desert regions,  as well as widespread species,”  Huiming Zhang and co-authors alleged.

“The mechanism operated primarily through land conversion:  cropland and grassland were transformed into developed areas,  reducing the diversity of vegetation,”  suggested Huiming Zhang and co-authors.
“Paradoxically,”  Huiming Zhang and co-authors continued,  “the leaf area index increased,  a pattern we term ‘inferior greening,’  whereby diverse natural landscapes were replaced by dense but ecologically homogeneous vegetation.  We argue that future photovoltaic development should be accompanied by strict biodiversity safeguards,  especially in economically developed regions with high habitat complexity.”
Offered Issam Ahmed for PhysOrg,  an online science and technology periodical published since 2004,  “China’s goal to achieve carbon neutrality before 2060 has seen it embark on a renewables revolution,”  largely meaning replacing coal with solar energy wherever possible.

“By 2024,”  Issam Ahmed observed,  the Chinese “solar footprint,”  meaning the area occupied by solar panels,  “reached an estimated 1,745 square miles—equivalent in size to the U.S. state of Rhode Island—and solar energy is projected to constitute 45% of its energy mix by 2060.”
Unfortunately,  Ahmed wrote,  “Choosing solar locations in China is not based on sunshine and available land,  but rather on government ‘Five-Year Plans’ to promote economic development in certain regions.”
Further,  Chinese solar development has so far relied much more heavily on “solar farms,”  or vast arrays of solar panels blanketing landscapes,  feeding electricity into existing transmission grids,  than on rooftop solar,  which in most efficient form,  bypasses transmission grids by storing electricity in batteries for use at or near the point of generation.
“The average effect [on birds],”  of covering land with solar panels,  “is modest,  but it is meaningful when it occurs systematically across many counties,”  Zhang Huiming and co-authors said in a media statement.

Explained Phil McKenna for Inside Climate News,  “In their multi-step assessment, the researchers first collected official solar-related directives from provincial,  city,  and county government websites.
“They then collected ‘citizen science’ bird-watching records from across the country. These records were fed into the Shannon Index,  a formula frequently used to assess biodiversity based on the number of species observed and how evenly individuals are distributed among them.
“Comparing the two indexes revealed how policies supporting solar power development impacted avian communities.

Amanda Rodewald,  senior director of the Center for Avian Population Studies at the Cornell University Ornithology Laboratory,  emailed to McKenna that,  “In North America,  we see similar patterns where species diversity often declines in areas developed for [solar energy collection],  due to loss of sensitive/specialist species.”
“However,”  McKenna continued,  “Rodewald said that species diversity can also increase after landscapes are initially fragmented.  She cautioned that bird species diversity may not necessarily be the most meaningful measure of the health of avian species in an area.
“Rodewald added that while some may be tempted to use the study’s findings to challenge renewable energy development,”  McKenna paraphrased,  “it is important to compare the effects of such projects with those of conventional energy sources like coal and oil,  which have steep environmental consequences,”  including for birds,  from the proverbial canaries in coal mines to the sea birds who die in oil spills at the rate of half a million to a million per year,  worldwide.
Zhang and co-authors acknowledged by email,  McKenna wrote,  that “Using rooftop solar in habitat-rich regions and restoring diverse native vegetation,  rather than relying only on simple greening targets,”  could mitigate the alleged avian biodiversity losses due to “solar farming.”

Huiming Zhang and co-authors were fiercely rebutted,  eleven days after “China’s Solar Expansion Policy Reduces Bird Diversity” appeared,  by Oliver Zhen Li of National University of Singapore and Shirley Jiexuan Wang,  who are respectively an economist and a systems analyst.
            “We revisit this issue and conclude that there is no evidence of this being the case,”  began Wang and Li.  “If we assume that Zhang et al’s data treatment is true and fair,  then they have ignored the fact that fences around solar farms can deny birdwatching access,  mechanically causing observed bird diversity to decline.
“However,  and more importantly,”  Li and Wang argued,  zeroing in on statistical methodology,  “the negative link between bird diversity and solar photovoltaic policy stringency claimed by Zhang et al is likely due to missing-data treatment-setting miss values to zero.
“Without setting missing values to zero,”  Li and Wang found,  “the correlation between solar photovoltaic policy intensity and solar photovoltaic activities is negative.”
Finished Li and Wang,  “Zhang et al‘s conclusion can potentially misguide sustainability efforts and energy policies in China as well as the rest of the world.”

Even more damaging to “China’s Solar Expansion Policy Reduces Bird Diversity” should be the critique issued by the China Ornithological Society,  whose members were the major source of the data used by Zhang et al.
“The data used to plug into a bird diversity index,”  the index used by Zhang et al,  “was taken from the China Birdwatching Record Centre,  the largest citizen-science platform for bird observations in the country,”  explained Victoria Bela for the South China Morning Post on September 6,  2026.
The China Ornithological Society,  however,  “warned of potential errors in the China Birdwatching Record Centre’s records,  which it said may have influenced”  the conclusions of Zhang et al.

The China Ornithological Society,  summarized Bela,  “pointed to a logged observation in 2015 of 2.1 billion little egrets in a wetland,  and another in 2022 of 1.3 billion red-billed blue magpies in a park,  both in Guangdong province.
“While there is no exact census for these species,  historical estimates show that those numbers far exceed their entire global populations.  A 2023 Wetlands International estimate placed the global little egret population at up to around three million,”  only 1.4% of the number supposedly found in a single wetland.
The China Ornithological Society,  reported Bela,   “said that despite the data clearly exceeding ‘reasonable limits,’  it was still included” in the estimate of avian biodiversity that Zhang et al used to allege a decline.
“China’s Solar Expansion Policy Reduces Bird Diversity,”  charged the China Ornithological Society,  “provides no information on birdwatching data quality control,  making it impossible to accurately assess the reasonableness of the data used for analysis.”

Detailed Jiang Xinyi for the Shanghai-based online periodical SixthTone.com,  “Among the issues, over 40% of the over 500,000 reports collected during the nine years [worth of data used by Zhang et al] recorded the presence of species using the number 1,”  instead of entering a count.  This does not actually mean “that only one bird was seen,”  the China Ornithological Society said,  “making the data unreliable.”
“Meanwhile,  the original study may have removed some migratory waterbirds’ records at wintering sites as statistical outliers,  as they recorded tens of thousands of birds at a given location, ‘potentially underestimating true bird diversity,’”  the China Ornithological Society explained.
“The China Ornithological Society also noted,”   Jiang Xinyi continued,  “that birdwatching records surged between 2021 and 2023 amid a growing birdwatching boom in the country,  just as authorities were introducing significant solar policies.  This,  it argued,  makes it difficult to determine whether changes in biodiversity data were driven by increased birdwatching or photovoltaic development.”

Ma Zhijun,  deputy director of the China Ornithological Society and a professor at the Fudan University School of Life Sciences,  told Jiang Xinyi,  Jiang Xinyi paraphrased,  that “Easy availability of birdwatching datasets has led researchers without a background in bird ecology to use them without fully understanding their limitations.”
Longer birdwatching time,  the China Ornithological Society added,  had a greater influence on observed avian biodiversity than anything having to do with solar policy.
Concluded the China Ornithological Society,  “We believe that this paper has flaws in data usage and statistical bias,  and cannot support the conclusion that China’s photovoltaic expansion policy has reduced bird diversity.”

Science communications director Meagan Phelan acknowledged on August 27,  2026 that “potential concerns related to this paper have reached our attention.”
“We are evaluating them following our normal processes,”  Phelan said.  “We will reach the authors.  If any adjustments are required,  we will certainly make them.”
“Ken Rosenberg,  a conservation scientist at Cornell University who was not involved in the research,  says bird diversity measures can be misleading,”  reported Mary Randolph for Scientific American,  “as they can obscure how well a specific local bird population is actually doing. Future research might look at bird population numbers instead,  he says.”
Rosenberg conceded,  however,  that the analysis by Zhang et al was “the first he has seen,”  Randolph wrote,  “that has looked at the relationship between solar policy and biodiversity on a national level.”

Hou Liqiang,  writing for China Daily,  the official Chinese government newspaper,  pointed out that,  “No form of human development leaves nature untouched,  and solar power is no exception. Almost every modern infrastructure — be it roads,  cities, farms,  mines and dams — reshapes ecosystems in one way or another.”
The question raised by Zhang et al,  Hou Liqiang suggested,  “is not whether solar energy development has any adverse ecological effect,  but how that effect should be assessed and reduced in a broader balance sheet.
“Some Western media outlets have framed the study in highly negative terms,”  Hou Liqiang observed,  “with one headline saying solar panels in China are ‘killing’ bird diversity.  The wording might be eye-catching,  but it risks turning a complex governance issue into a simplistic accusation.
“The study itself does not conclude that solar power is inherently harmful.  Nor does it deny the significant role that renewable energy plays in mitigating the threat from climate change that has been looming larger.

“After all,  climate change itself is triggering extreme weather events and destroying habitats, exacerbating global biodiversity loss,”  Hou Liqiang reminded.  “By mitigating climate change, the development of solar energy can play an important role in promoting biodiversity conservation.”
Agreed Darren Orf for Yahoo.com,  “Renewable energy is the solution for the climate crisis. Severely curtailing carbon emissions while harnessing the free energy provided by the fusion reactor known as our sun (in the form of solar power) or the wind blowing across the plains is a clear win-win for humanity,  but that doesn’t mean that energy sources like this don’t come with downsides that require careful consideration.
“For instance,  400-foot-tall wind turbines and sprawling photovoltaic arrays need space,  often to the detriment of the wild animals that rely on those once-undisturbed habitats.”

But Ted Clifton of Zero Energy Plans,  a pioneering solar builder and brother and brother-in-law of the ANIMALS 24-7 team,  argues that the whole premise that solar conversion requires “sprawling photovoltaic arrays” eating into wildlife habitat and farmland is just plain wrong.
“I have never been a fan of ground-mounted arrays,”  Ted Clifton emailed,  “as we have more than enough rooftops,  especially in warehouse districts,  to supply all the power we need,  closer to the actual point of use.

“In very far northern climates,”  Ted Clifton continued,  “ground-mounted arrays can be set steep enough to dump snow,  and still be effective during the winter months,  but otherwise we should be keeping them on rooftops.”

IEA Sees Major Rooftop Solar Potential in Türkiye – Caspian Post

Source: Anadolu Agency

Türkiye could add around 120 gigawatts (GW) of solar photovoltaic (PV) capacity through rooftop installations, which would be enough to meet 45% of the country’s electricity demand if fully developed, according to the International Energy Agency (IEA).
The expansion of rooftop solar could help decentralize electricity generation, reduce reliance on centralized energy systems and increase the share of solar power in Türkiye’s electricity mix, the IEA said in its “Türkiye Energy Policy Review,” The Caspian Post reports, citing Anadolu Agency.
The model could also reduce dependence on energy generation subsidies while allowing consumers to produce electricity at more affordable costs.
Türkiye’s three most populous cities – Istanbul in the northwest, Ankara in central Türkiye and Izmir on the Aegean coast – also have the country’s highest rooftop solar potential.
According to the report, expanding rooftop solar is important not only for increasing renewable energy capacity but also for strengthening energy security.
Rooftop solar systems could contribute to a more resilient and decentralized energy system by helping maintain electricity supply, at least to some extent, when centralized energy systems are disrupted by natural disasters such as earthquakes.
Despite the advantages of rooftop solar PV compared with large-scale solar power plants, its deployment continues to face regulatory and practical challenges.
In 2019, Türkiye introduced a monthly net metering system that allows residential solar users to sell excess electricity at consumer rates.
However, the length of the installation process remains one of the factors limiting the expansion of rooftop solar. The process, which requires approval from multiple authorities between application and installation, can take up to 27 weeks.
Türkiye is implementing a series of reforms and investments to achieve its 2035 wind and solar energy targets.
Legal amendments introduced on July 24, 2025, paved the way for reducing the permitting process for wind and solar power plants from approximately 48 months to 18 months.
Further improvements to application procedures, along with requirements for rooftop solar systems on new and public buildings, could help Türkiye advance its energy and self-sufficiency targets while enabling consumers to generate electricity at lower costs.
Solar photovoltaic (PV) technology has benefited most from Türkiye’s unlicensed electricity generation regime, which has driven a rapid increase in rooftop solar installations, particularly in the residential and agricultural sectors.
Solar PV accounted for 97% of the country’s unlicensed electricity generation capacity, or approximately 23 GW, at the end of 2025.
According to the report, strengthening distributed energy infrastructure will be important to further expand this capacity, while smart meters are expected to support the development of small-scale, distributed and renewable energy infrastructure.
A key objective of the roadmap is to add 35 GW of flexible resources to the electricity system.
Of this total, 10 GW will come from rooftop solar combined with storage, 10 GW from large-scale energy storage, 5 GW from grid management and 10 GW from demand-side management.
With the expansion of distributed generation, the deployment of smart meters and increased energy storage capacity, rooftop solar is expected to play a greater role in Türkiye’s electricity system, both by increasing the share of renewable energy and strengthening energy security.

Stafford County Zoning board awards conditional use permit to proceed with solar project – Great Bend Tribune

ST. JOHN – Following a two-hour public hearing at the Annex Building Community Room in St. John, the Stafford County Zoning Board on Wednesday evening voted 4-2 to grant a conditional use permit to Lightsource BP US to construct a solar farm and battery storage facility spanning roughly 2,400 acres in the county.
Lightsource BP, founded in London in 2010 and fully acquired by energy giant BP in 2024, is one of the world’s largest developers and operators of utility-scale solar projects. The company operates in more than a dozen countries and has an existing presence in Kansas, having previously signed a long-term power purchase agreement in Stanton County. The Zion Valley project in Stafford County would add to its growing U.S. portfolio.

Public hearing
The public hearing followed an open house hosted by the company on Aug. 19 regarding the proposed Zion Valley Solar and Storage project. Preceding the event, announcement of the public hearing was published by the Great Bend Tribune as the official newspaper for Stafford County on Aug. 11. Approximately 30 Stafford County residents attended the hearing Wednesday, which featured three representatives from the Lightsource BP organization presenting the application for the conditional use permit.
Matt Miller, zoning board chairman, noted that notice of the hearing was mailed to the applicant, as well as 29 property owners in the area affected by the proposed construction project.
Zoning board administrator Carl Miller noted that zoning regulations were adopted in March addressing concerns for both the solar energy facility and commercial energy lithium battery storage system. The regulations defined parameters for fenced panel array, storage system and its design requirements, setbacks from residences, public structures, cemeteries and private airstrips that may be adjacent to the construction.
Requirements also included a complete development plan presented by appropriate maps, diagrams or plans that designate the total acreage for the project, names and current addresses of property owners providing leases or licenses; fire safety plan, road agreement, state required soil erosion, sediment control and storm-water runoff plan, post-construction cleanup and decommissioning plan revised every five years.
Following public comment that included concerns from the audience regarding meeting notice for neighbors not directly affected by the project’s location, the six-person voting membership cast a 4-2 vote, with members Jenna Zeman and Darryl Lucas opposed, authorizing the board chairman to sign a resolution granting conditional use permission for Lightsource to proceed with the project.
Project parameters
As explained by Alyssa Edwards, senior vice president of environmental affairs and government relations, Lightsource BP staff worked through the permit application step-by-step in accordance with the zoning regulations.
“We have worked with landowners, neighbors, hosted a public information meeting and so we have been in the area since 2024. We feel that our application reflects the ordinance and all the items were addressed,” she noted.
While the total area of the project at a planned 342-megawatt capacity spans roughly 2,400 acres, the fenced-in facility with panels and batteries is estimated at 1,800 acres. The project represents a capital investment of approximately $300 million in Stafford County.
Adam Iago, Lightsource senior development manager, noted that drawings and renderings represent the project in draft form, as final engineering has yet to be completed. A firm construction schedule with target completion date remains to be determined.

Goodyear approves Desert Rainbow Solar Project – West Valley View

Partly cloudy. High 109F. Winds WSW at 10 to 15 mph..
Some passing clouds. Low 86F. Winds SW at 10 to 20 mph.
Updated: September 9, 2026 @ 12:13 pm
The Goodyear City Council approved a special use permit for a sprawling solar energy and battery storage project in south Goodyear. 
 The Desert Rainbow Solar project is a utility-scale solar energy generation facility planned on approximately 5,050 acres south of Queen Creek Road and east of Waterman Wash. 

The Goodyear City Council approved a special use permit for a sprawling solar energy and battery storage project in south Goodyear. 
The Goodyear City Council approved a special use permit for a sprawling solar energy and battery storage project in south Goodyear that is expected to generate millions of dollars in tax revenue and hundreds of construction jobs.
The council voted 6-1 to approve Resolution No. 2026-2537 for the Desert Rainbow Solar Project, a utility-scale solar energy generation facility planned on approximately 5,050 acres south of Queen Creek Road and east of Waterman Wash. Councilmember Benita Beckles cast the lone dissenting vote.
The project will include photovoltaic solar panels, a battery energy storage system, electrical infrastructure, a collector substation and at least one operations and maintenance building.
Principal Planner Ann Dolmage said the property is currently undeveloped and is zoned Estrella Phase 3 Preliminary Planned Area Development, or PAD. The preliminary PAD envisioned residential, commercial, mixed-use, light industrial, public and open-space uses for the property, but a final PAD was never approved.
“Under the zoning ordinance in effect at the time of application, energy generation facilities are allowed in any zoning district with approval of a special use permit,” Dolmage said.
 The Desert Rainbow Solar project is a utility-scale solar energy generation facility planned on approximately 5,050 acres south of Queen Creek Road and east of Waterman Wash. 
Dolmage said the solar panels would stand approximately 10 to 15 feet high and use trackers to follow the sun throughout the day. The battery energy storage system, or BESS, would store surplus electricity so it could be deployed when needed.
The project would have a 30-foot setback around its perimeter, while battery storage units would have to remain at least 100 feet from the perimeter and any buildings.
The project would not connect to the city’s water or sewer systems, with water instead trucked to the site or supplied through on-site wells.
“For the BESS, the applicant will be required to provide a hazard mitigation plan, as well as an emergency response plan,” Dolmage said. “The BESS units will also include an intelligent fire detection, alarm and suppression system.”
Dolmage also highlighted environmental considerations associated with the approximately 5,050-acre site, which falls within wildlife movement areas identified by the Arizona Game and Fish Department and other agencies.
“The applicants have been consulting with Game and Fish, and they’ve obtained a biological study for the project,” Dolmage said. “One recommendation of the study is for a wildlife corridor through the site, and that will be accommodated near Chandler Heights Road.”
Dolmage said AES is requesting up to 10 years to establish the use and anticipates the facility operating for approximately 40 years. The requested special use permit would have a 45-year term.
“At which point the solar park must be decommissioned, or an SUP extension must be obtained,” Dolmage said. “A final decommissioning plan will be provided before construction.”
The project would be developed by AES Clean Energy on private land currently owned by Estrella South LLC.
Andrew Yancey, an attorney representing AES, said the project is expected to produce approximately 550 megawatts of electricity while placing little demand on Goodyear’s municipal infrastructure.
“The project is a way to make beneficial use of otherwise unproductive land for the next 40 years or so and to provide additional electricity to help Arizona’s economic growth overall,” Yancey said.
AES has submitted the project as part of Salt River Project’s request for proposals process. Arizona Public Service, which serves much of Goodyear, also expressed support for the project.
According to a fiscal impact analysis provided by the applicant, the solar portion is estimated to generate approximately $42.9 million in direct tax revenue for Goodyear over 30 years, while the battery energy storage component is projected to generate another $15.5 million over 15 years.
Dolmage said the project has undergone review by several outside agencies, including the Arizona Game and Fish Department, Arizona Department of Transportation, city of Avondale and Maricopa County.
The city also expanded its public notification area from the usual 500 feet to 1 mile around the project site.
“The city has received comments from 14 individuals and organizations about this project,” Dolmage said. “Of these comments, most have expressed support for the project or simply requested more information about it.”
Three neighboring property owners raised concerns about access and whether the project would promote desirable development in south Goodyear, according to Dolmage.
Yancey said the project could also create up to 800 construction jobs and approximately 20 full-time positions once operational.
The project prompted considerable discussion among council members over fire safety, decommissioning, wildlife protection and the long-term future of the property.
Councilmember Trey Terry questioned what safeguards would be in place to ensure the property is properly decommissioned if AES or another future owner is unable to complete the work.
AES has submitted a preliminary decommissioning plan and will be required to provide an updated plan before construction. The company is requesting a 45-year term for the special use permit, with the project expected to operate for approximately 40 years.
“I just want to make sure we protect the city and maintain flexibility for people 45 or 50 years from now,” Terry said.
Fire safety surrounding the battery energy storage system was another major topic.
Goodyear Fire Chief Paul Luizzi said the remote location and lack of fire hydrants would require additional considerations in an emergency response. The project will be required to develop an emergency response plan in coordination with the fire department.
“We would, more than likely, require water storage on-site for any fire protection,” Luizzi said.
AES representatives said battery units would include monitoring and fire-suppression technology and would be designed according to applicable safety standards.
Wildlife protection also factored into the project’s design. Approximately 730 acres around Waterman Wash are expected to remain preserved, and the project includes plans for a wildlife corridor near Chandler Heights Road. AES has been working with the Arizona Game and Fish Department and plans to continue that coordination as the project moves through permitting.
Councilmember Laura Kaino said Arizona’s continued economic and technological growth makes additional energy infrastructure increasingly important.
“Arizona’s economy depends on energy, just as it depends on water,” Kaino said. “Energy is just as important a conversation as water is right now.”
Beckles said she supports solar and battery storage technologies but had concerns about the specific project, including its decommissioning and emergency planning.
“I don’t have any further questions, but I am not in favor of this project,” Beckles said.
Councilmembers Wally Campbell and Vicki Gillis voiced support, citing the need for additional electricity as the region continues to grow.
Gillis said her position on battery storage changed after spending several years researching the technology and touring facilities.
“I was not for it, and now I’m strongly in favor of it,” Gillis said. “I think we need it. If not now, then when?”
Mayor Joe Pizzillo also supported the proposal and said he has toured similar facilities.
The Planning and Zoning Commission previously voted 6-0 on Aug. 19 to recommend approval of the special use permit.
If the project receives its remaining outside permits and approvals, construction could begin as early as 2029.

Virginia Gov. Abigail Spanberger, Solar United Neighbors and their partners are launching the Switch Together initiative that will help lower the cost of rooftop solar for homeowners. The program is available through Oct. 15.
Switch Together leverages bulk buying power to get customers discounts. People can sign up on Switch Together’s website and enter details about their home. Then, companies must bid each other for people’s business. The customer can review the offers and schedule a consultation if they like what they see.
According to Virginia’s Chief Energy Officer Josephus Allmond, homeowners can expect a 23% discount on their installation. People can also get discounts on battery storage and, in some places, heat pumps. The program is estimated to save the average household approximately $2,200 a year on electricity costs, according to the U.S. Department of the Treasury.
This program comes after the One Big Beautiful Bill Act terminated the $156 million federal Solar for All program, which provided grants to low-income individuals for solar installation.
The program is available to 100 localities in Virginia, or 85% of the state. Brandon Praileau, Solar United Neighbors’ Virginia program director, expects the program to be available statewide by next year.

Is a bigger solar system always better? – RNZ

Homeowners installing solar power systems may get a better return from a slightly bigger system.
Kristy Hoare, managing director of My Solar Quotes, says she analysed 279 residential solar quotes provided to New Zealand homeowners this year and found the median payback for a system without a battery was 6.9 years.
But systems under 5kW performed much more poorly, with a payback period of 11.1 years. Depending on the output, this could be about a dozen panels.
She said smaller systems had a median price of $11,490.
But slightly bigger systems, with a median cost of $12,148 and delivering up to 7kW, had a payback time of 6.6 years.
Hoare calculated that all systems between 7kW and 20 kW would have payback periods between 6.8 and 7.7 years.
"A huge part of the system cost is actually in the labour," she said. "You get someone out to your house and you have to put scaffolding on… just that cost alone makes the smaller systems not as good for payback."
More than half of solar quotes included a battery, she said.
That would increase the median payback for all systems to nine years because it would roughly double the price of the system. She said about 30 percent of people went on to install batteries.
"The value isn't only in the payback with batteries, it's the energy resilience side. Being able to power your home during a power outage is incredibly valuable."
A spokesperson for Rewiring NZ said it would always recommend people opted for a bigger system if they could, because many households would increase their power use once solar was installed.
"We've heard from a lot of installers – more at the high end – that 9kw systems are the norm in New Zealand now. This is quite a long way above what EECA says is the average and about what the average has been in Australia in recent years. In Australia, this is actually increasing, in part because of the battery subsidy and EV adoption, solar system size is also growing.
"We know people love a payback period, but we do like to point out that it's better to look at ROI or yearly net savings in comparison to doing nothing."
Rewiring calculated that solar should deliver $1000 a year in savings on top of the cost of paying off the system.
Gareth Williams, chief operating officer of the Sustainable Energy Association of New Zealand, agreed the incremental cost of adding more panels to a system was relatively low.
"A 7 kW system may cost $14,000. The cost of another kW – roughly two panels more – would add only about $1000. The effective cost of energy that the extra panels generate is only around 5c/kWh – which is therefore worthwhile based just on export value. Furthermore, in winter or on overcast days the extra generation will have higher value in offsetting homeload.
"In terms of balcony solar the payback period is similar to larger rooftop solar systems; however, the long-term savings are significantly lower."
Powerswitch general manager Paul Fuge said one of the most important factors affecting solar payback was whether people were with the right retailer and on the right plan.
"Solar buy-back rates, which determine how much you're paid for excess electricity exported to the grid, can vary significantly between retailers, from around 8 cents per kWh to more than 20 cents per kWh in some cases.
"Batteries can also play an important role. On some electricity plans, households can effectively arbitrage electricity prices by storing energy when prices are low and exporting it, when prices are high.
"However, being able to do so is contingent on being on the right electricity plan. At present, only a relatively small number of plans offer pricing structures that make this worthwhile, although we expect more retailers to introduce these types of products as solar and battery uptake grows."
He said it was difficult to draw broad conclusions about how long a system would take to pay for itself based only on its size.
"While larger systems can often be more economical on a cost-per-watt basis because installation costs don't increase proportionately with system size, it would be wrong to assume that a larger system will always deliver a faster payback for every household. Payback is highly household-specific and depends on a range of factors that can vary from one home to the next.
"A key consideration is how much of the electricity generated by the solar system is consumed within the home. Self-consumed solar power is generally worth more to the household than exported electricity because it offsets power that would otherwise be purchased from the grid at higher retail rates. By contrast, electricity exported to the grid is usually paid out at a lower rate than the price consumers pay for grid-supplied electricity. Simply put, retailers buy electricity from you for less than they sell it back to you.
"This means system sizing can be critical for payback. A small household installing a large solar system will export a significant proportion of its generation, extending the payback period. Conversely, a larger household with higher electricity use may be able to utilise more of the energy generated and achieve a faster return on investment."
He said it was important to choose a reputable installer that did not have incentives to sell larger systems than a household needed.
Power retailer Octopus said solar generation had increased 56 percent last year and it was seeing more customers install bigger systems. "We expect this change in market prices to continue to become more pronounced, we've seen in countries around the world that as solar penetration grows those day time energy prices fall."
It said that it had led it to launch a new pricing plan that gave free power between 11am and 2pm everyday.

EU clean-energy jobs on the rise – Eunews

Home » Ambiente » EU clean‑energy jobs rise, but skilled labour is lacking

Brussels – Jobs linked to clean energy technologies are on the rise in the European Union, but the persistent shortage of skilled labour risks slowing future growth. This problem is compounded by the challenge of inclusion posed by the under-representation of women and young people in the renewables sector, according to a report published today (9 September) by the European Environment Agency (EEA). 
In 2024, employment in the global energy sector rose by 2.2 per cent, compared with 1.3 per cent growth in employment across the wider economy. Against this backdrop, the EU ranks second, with a total of 1.8 million jobs directly or indirectly linked to renewable energy. China ranks first, with 7 million jobs in the clean energy sector. 
Examining four clean energy technologies, the report explains that wind energy employs the most workers, with an estimated 273,500 direct jobs in the EU in 2023. 77 per cent of these are concentrated in the downstream activities segment (maintenance, energy contracting, and sales administration), followed by manufacturing. Solar photovoltaic (PV) technology directly employed over 227,000 people in 2023: around half were employed in operational activities, and 36 per cent in the construction segment (including infrastructure works, site preparation, and grid connection), although PV system production in the EU remains limited. The heat pump sector employed around 80,100 workers in 2023, mainly in the construction segment (65 per cent), and has significant potential for further growth across the EU. The battery sector, although smaller (around 33,000 workers), recorded the fastest employment growth among the four technologies over the period 2018–2023, with most jobs concentrated in manufacturing.
 Geographically, the situation across the EU is “uneven”. “Germany accounts for the largest absolute workforce in wind (125,000 jobs in 2023), solar PV (nearly 84,000 jobs) and batteries (12,300 jobs), though not the largest share of total employment,” the report explains. “Portugal, Spain and Italy lead in heat pump jobs, while Hungary and Poland show the fastest employment growth in batteries,” it adds. 
However, the report highlights that employment growth in the clean energy sector does not automatically translate into inclusive labour markets: female participation ranges from 26 per cent in the wind power and battery sectors to just 14 per cent in the heat pump sector; furthermore, in 2023, young workers (aged between 15 and 24) accounted for only 6–7 per cent of the workforce in the wind power, solar photovoltaic and heat pump sectors. 
For this reason, the EEA’s warning is clear: “Skill shortages threaten the deployment of clean energy technologies and most Member States report gaps in critical installation- and construction-related technical roles. Coordinated policy action is needed to expand training, reskilling and workforce availability at scale.
According to the Agency, the quality of work also “varies considerably” depending on the technologies and segments of the value chain. “Wages in the heat pump sector are around 40 per cent lower than in wind, the highest-paid of the four sectors,” the report notes. Operations and maintenance roles, more common in wind energy, “tend to offer stable employment and stronger access to training. Construction and installation roles in solar PV and heat pumps are more project-based, more exposed to physical risks such as extreme temperatures, and offer fewer training opportunities.” Finally, “battery manufacturing’s impact on workers’ health and safety, as well as on local communities and the environment, remains a persistent source of concern.” In this context, the report calls for “coordinated policy action to expand training and reskilling, alongside improvements in job quality, to attract and retain workers in a sector facing acute shortages.”

Some Like It Hot: Agrivoltaics Grow More Hot Peppers – uk.news.yahoo.com

Enjoying a spicy pepper
Solar energy is the cheapest in history, but it does have some issues. A continuing challenge in large-scale solar photovoltaic (PV) deployments is land use, which can be overcome with agrivoltaics particularly when integrated into controlled environmental agriculture. Agrivoltaics is the combination of solar energy and agriculture. Many crops increase their output with solar in the fields but less has been done with solar panels integrated into greenhouse rooftops. For greenhouse rooftops generally semi-transparent solar panels are used. Agrivoltaic greenhouses work well with tomatoes. Peppers are another common food crop grown in controlled environmental agriculture like greenhouses, but research investigating impacts of different semi-transparent photovoltaic agrivoltaic systems on hot peppers in northern regions was lacking. For this, a new study investigated the impact of partial solar shading on hot peppers in greenhouse.
In the study a group of six semi-transparent photovoltaic modules with different materials, transparencies, and spectrum filtrations were deployed in greenhouses to compare their impacts on an Italian spicy peppers, Piccante De Cayenna, with those in the control greenhouse in Ilderton, Ontario.
Plant height, leaf chlorophyll content, and fresh harvested weight were measured. All the agrivoltaic treatments increased yield, however, 50%-transparent thin film-blue increased by 78%, 69%-transparent, red-colored luminescent solar concentrator crystalline silicon increased by 91%, and 44%-transparent patterned crystalline silicon solar cells improved yields by 138% compared to controls. The bottom line is you can get more than twice as much peppers by choosing agrivoltaic shading carefully.
Rooftop agrivoltaic energy simulations were conducted in SAM for a 1-acre greenhouse model whose rooftops can be integrated by the top three performing agrivoltaic modules. 123 kWdc for 50%-thin film-blue would produce 137,452 kWh/acre (278% of greenhouse needs) and the 69%- luminescent solar concentrator -red would house 98 kWdc covering 99,182 kWh/acre that is more than 200% of needs, and finally 266 kWdc for the 44%-c-Si would generate 255,297 kWh/acre annually and potentially produce over 516% of the greenhouse's annual loads. All three of the top selections could power the greenhouses and have energy left over for other applications or to feet back to the grid.
The study concluded that the agrivoltaic greenhouses with semi-transparent solar modules that produced the highest yield of spicy peppers could also operate as net-sustainable energy exporters.

Croatia backs rooftop solar with €38 million programme – pveurope.eu

 
A new funding framework introduces higher grants for lower-income households and, for the first time, dedicated support for battery systems alongside solar and heat pumps.
Croatian Minister for Environmental Protection and Green Transition Marija Vučković has presented a subsidy scheme for residential renewable energy systems, battery storage and heat pumps. The proposal has entered public consultation, with a total of €38 million in funding to be administered by the Fund for Environmental Protection and Energy Efficiency (FZOEU).
Get the latest market updates for solar investors – sign up for our monthly newsletter
This marks the first time Zagreb is supporting the installation of storage systems, as FZOEU Director Luka Balen emphasised at the programme’s launch, also highlighting significantly increased subsidies for photovoltaic systems.
A key element of the programme is that households affected by energy poverty receive higher grants than more affluent households. Zagreb is supporting the installation of photovoltaic systems, storage and heat pumps with grants covering up to 50 percent of eligible costs, rising to 70 percent for lower-income households. Eligibility depends on total household income: households with an average monthly income below €1,341.42 in 2025 qualify for the additional support.
Based on these percentages, subsidies for heat pumps range from €6,250 to €8,750. For photovoltaic systems, households can expect between €6,000 and €8,400. Battery system installations are supported with grants of between €5,600 and €7,840 per system. The government is allocating the funds differently depending on the technology: €10 million is earmarked for heat pumps for hot water preparation, €20 million for solar power systems and an additional €8 million for battery storage.
Croatia – grid batteries can ease renewable bottlenecks
The programme is aimed at owners and co-owners of single-family homes who live in the building where the system is to be installed. The building must have been legally constructed and comply with the relevant technical requirements. For heat pump installations, the house must have energy class C if located inland. Coastal properties must achieve at least energy class B. (su)

Families sell gold for solar as generator power climbs to $250 a month in Syria – The Cool Down

“Generators also frequently break down, leaving us without electricity when we need it.”

In the northeastern Syrian city of Qamishli, some families are selling gold and jewelry to pay for rooftop solar panels as unreliable public electricity and rising generator prices strain household budgets.
For many households, the economics are becoming hard to ignore. With round-the-clock generator power climbing toward $250 a month, solar is starting to look like the cheaper long-term option.
According to Rudaw, more residents in Qamishli are choosing solar systems as they juggle inconsistent grid electricity and steeper private generator bills. The upfront price is still hard for many families to meet, leading some to borrow from relatives or sell gold and jewelry.
Fadi Jardo, a solar panel supplier in Qamishli, told Rudaw that a household that needs 10 amperes continuously would spend roughly $200 to $250 each month — nearly $3,000 over a year — because private service costs “$20 to $25 per ampere per month.”
Jardo said the price comparison is changing minds: “That is why residents are considering [buying] solar panels, because for the same price they can get a complete system that provides 20 amperes of electricity, with lithium batteries that have warranties ranging from five to 15 years. There are also cheaper systems available between $1,000 and $1,500 that can provide eight amperes of electricity.”
Generator operators are feeling the impact of that shift. Mohammed Marwan, who runs a private generator serving about 250 subscribers, told Rudaw that the amount of power he supplies fell from 1,300 amperes to 300 amperes as more residents installed solar panels.

Fuel prices remain central to generator costs. Marwan told Rudaw he buys diesel at about $3.03 per gallon (80 cents per liter), though some of his fuel is subsidized at roughly 4 cents per gallon (about one cent per liter). Rudaw reported that local authorities in Qamishli set July’s generator rate at $25 per ampere for 24-hour service, while an unsubsidized eight-hour option was set at $12 per ampere.
Ala Rezan, a Qamishli resident who installed a system, said, “In Qamishli, all these private generators have caused dirty smoke and very disturbing noise throughout the neighborhoods and the city. In addition, their wires hang over streets and buildings like spider webs, making the city look ugly.”
To make systems more attainable, some suppliers in Qamishli are offering credit or short installment arrangements. 
Jardo said, “Some people whom we know personally and who are not in a good financial situation are sold panels on credit or through short-term installment plans as a form of assistance so that they can benefit from them.”
Getting equipment into the region is another obstacle. Jardo told Rudaw that traders route supplies from Jordan and the Turkish port city of Mersin to Damascus before moving them into northeast Syria, while customs fees on other routes can sharply raise costs.
For homeowners elsewhere who are considering solar, services such as EnergySage can help you go solar by letting you curate competitive bids from local installers without them obtaining any of your contact information unless you choose to work with one further.
Rezan said, “Generators also frequently break down, leaving us without electricity when we need it. That is why solar energy is a more suitable and reliable solution.”
Qamishli’s move toward solar reflects a wider trend: When electricity gets too expensive or too unreliable, households start looking for more dependable options. These articles look at how that is playing out in places dealing with steep power bills, energy-security pressures, limited grid access, and the question of what solar really costs.
• In the Philippines, soaring power bills are pushing more households onto rooftops for solar.
• Across Southeast Asia, oil shock upends energy security as conflict accelerates solar planning.
• In rural Indonesia, life-changing access to electricity is arriving through village-scale solar systems.
• For U.S. homeowners, solar panel costs are getting easier to compare through EnergySage.
• In Australia, free solar panels became bait in a brazen online scam.
Across very different places, the calculation looks familiar. Solar ultimately comes down to cost, reliability, and access — the same pressures driving families in northeast Syria to seek dependable power.

Rubis to install 8 MW solar – Jamaica Gleaner

Loading article…
Rubis, global fuel distributor, signed a deal to install an 8-megawatt (MW) capacity solar plant in Jamaica in June, part of a renewable energy push that accompanied half-year financial results released Tuesday.
The Caribbean remains the group’s most important region by earnings, even as its profit margin now trails Africa’s.
“Rubis delivered a strong first-half performance in a volatile and high oil price environment, driven by solid activity levels, disciplined execution and active commercial management,” managing partners Clarisse Gobin-Swiecznik, Jean-Christian Bergeron and Marc Jacquot said in a statement accompanying the results.
The Caribbean generated €124 million of earnings before interest, taxation, depreciation, and amortisation (EBITDA) on revenue of €1.81 billion in the first half, the largest earnings contribution of any Rubis region. Africa followed with €122 million of EBITDA on revenue of €1.73 billion. Europe was third, with earnings of some €78 million. On a margin basis, Africa’s EBITDA came in at just over 7.0 per cent of revenue, narrowly ahead of the Caribbean’s roughly 6.9 per cent.
Africa led on volume throughout the half, selling 1.55 million cubic metres against the Caribbean’s 1.32 million. But Caribbean volumes rose 10 per cent year-on-year, more than Africa’s 3.0 per cent growth — a sign the region added considerably more product without a matching increase in profitability.
“In the Caribbean, Guyana remained one of the main contributors to volume growth, although margins were under pressure in a context of high oil price, while Haiti continued its recovery trajectory, supported by increased network activity and improving profitability,” Rubis stated in the preface to its financials.
On the solar deal, Rubis flagged it directly among its half-year highlights: “Half-year highlight — signing of an 8 MW project in Jamaica in June 2026.” The agreement follows an earlier solar installation drive two years ago. Group-wide, Rubis installed an additional 166 MW of solar plants and solutions during the half, up a third year-on-year, bringing its total installed solar capacity to 799 MW.
The Jamaica solar signing extends a commercial and industrial renewables push that Rubis is running across Africa and the Caribbean separately from Photosol, its French utility-scale renewables arm. The company operates in Jamaica through its wholly owned subsidiary, Rubis Energy Jamaica.
On supply security, the group said events in the Middle East did not negatively affect its operations or its ability to supply customers during the half, noting it has no operating activity in the region and manages sourcing regionally through diversified contracts.
Looking ahead, Rubis said it expects “sustained high oil prices to weigh on demand” globally through the remainder of its financial year. “However, at regional level, in the Caribbean, activity will remain supported by continued recovery in Haiti, tourism dynamism, and the development of the Guyana and Suriname economies,” the company added.
The Paris-listed company reported EBITDA of €434 million for the six months to June 30, up 18 per cent, on revenue of €4.07 billion. Net income rose 17 per cent to €191 million. Rubis raised its full-year EBITDA guidance to a range of €775 million to €825 million, from €740 million to €790 million previously.

Enphase Energy Rises 5% as Solid-State Transformer Modules Enter Texas Production, SolarEdge Jumps 6% – 24/7 Wall St.

A Texas factory just handed Enphase a credible claim on the AI data-center power market, and SolarEdge surged even harder despite announcing nothing at all.
Market Movers desk. Editor: David Moadel.

Solar names caught a midday bid on a manufacturing milestone tied to AI data-center power infrastructure. Enphase Energy (NASDAQ:ENPH | ENPH Price Prediction) said power modules for its IQ Solid-State Transformer, or IQ SST, are now being built at its Arlington, Texas facility, enabling full-scale racks to be assembled and validated for prospective data-center customers. SolarEdge Technologies (NASDAQ:SEDG) stock rallied in sympathy, boosted by its own SST platform aimed at the same AI-factory opportunity.
The Invesco Solar ETF (NYSEARCA:TAN) is up 3% on the session. Meanwhile, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.42%, framing solar as a clear day-of outperformer against a softer broad-market tape.
Enphase stock is up 5% to $38.31, extending its year-to-date gain to 20%. At the same time, SolarEdge stock is climbing 6% to $36.34, an outsized reaction given that the company hasn’t announced any news of its own today.
Each IQ SST power module is rated at 4 kW, and hundreds combine into a rack with capacity up to 5 MW. The design converts medium-voltage AC (13.8 kV or 34.5 kV) directly to 800-volt DC, with sub-millisecond response to the sharp load swings AI training and inference workloads generate, reducing the need for battery buffering next to every compute rack.
Co-founder and chief product officer Raghu Belur explained that hundreds of modules together make a multi-megawatt rack, and Enphase scales by repeating the same compact module rather than building larger power-conversion systems. The modules share their form factor and production process with the company’s microinverters, which makes the Texas milestone credible rather than a paper design.
Enphase’s management flagged customer engagement across hyperscalers, neoclouds, colocation providers, EPCs, and server providers, with opportunities at the RFI and RFP stages representing potential demand totaling multiple gigawatts. Full-system demonstrations remain on track for later this year, with customer pilots beginning in 2027 and commercial shipments in 2028.
SolarEdge’s own SST platform targets the same AI-factory build-out, and CEO Shuki Nir has framed the effort as addressing “the significant opportunity in AI factories.” On the company’s August 5 earnings call, SolarEdge said prospective customer engineering teams viewed a working prototype convert medium-voltage AC to a regulated 800-volt DC bus at 99% efficiency across a range of power levels.
SolarEdge’s roadmap points to a working lab system by the end of 2026, pilot installations in 2027, and volume shipments in 2028, mirroring Enphase’s commercialization schedule. Both names remain pre-revenue on the data-center side, and SolarEdge’s investor day on September 10, 2026 sits two days out as its next scheduled disclosure moment.
First Solar (NASDAQ:FSLR), the largest U.S. solar manufacturer, sits outside the SST story, though its 45.1-gigawatt contracted backlog through 2030 keeps it central to any broader rotation into domestic solar. First Solar stock is down 19% year to date, entering today’s sector move from a much weaker anchor than its two rallying sector peers.
The Invesco Solar ETF’s 3% session gain lags both SST-linked names by a wide margin, suggesting today’s bid is concentrated in the two companies with an explicit AI-data-center power narrative. That divergence underscores how selective the tape has been within the solar complex.
The AI-power thesis in solar names now has a factory address. A signed contract with a data-center operator remains ahead, and Enphase’s next tangible catalyst is a full-system IQ SST demonstration targeted for November, followed by customer pilots in 2027 and commercial shipments in 2028. SolarEdge’s Thursday investor day could validate today’s sympathy bid with firmer numbers around its data-center opportunity.
The bulls can argue that Enphase’s Texas line proves a residential-solar manufacturer can credibly extend into medium-voltage data-center gear using its existing production base. The bears could counter that SolarEdge outran Enphase today on no company-specific news, suggesting part of the move is a sector-wide bid that could fade if AI-power sentiment cools.
Investors sizing their exposure should treat both names as speculative AI-adjacent positions rather than solar-industrial staples, keeping their allocations modest ahead of SolarEdge’s investor day and Enphase’s late-year system demonstration. Position sizing matters more than usual given the pre-revenue status of both SST platforms.
