From ESS News
Chinese battery solutions maker Anker Solix has launched the Solarbank Max AC, a 7 kWh modular home battery system designed to retrofit existing rooftop solar installations, with a bidirectional 3.5 kW inverter and capacity expandable to 42 kWh.
The modular Solarbank Max AC battery system can now handle five additional LFP battery modules at 7 kWh each.
The product represents a step up in scale from Anker Solix’s existing Solarbank lineup in Europe, which has focused primarily on balcony solar systems.
The Solarbank 3 E2700 Pro, offers 2.688 kWh per unit and up to 16 kWh of total capacity, with an output of 800 W to 1,200 W. The Solarbank Multisystem, launched in August 2025, extended that further by allowing up to four Solarbank 3 Pro units to operate in parallel via a central Power Dock, reaching 64 kWh and 4.8 kW of AC output, as part of the Solarbank 3 ecosystem.
Now the Solarbank Max AC takes a different approach: a single, larger base unit aimed at households with existing rooftop PV that want battery storage without a full inverter replacement, and with plug-in functionality for DIYers.
Anker Solix says the system can be self-installed under certain conditions and in compliance with local regulations, which differ between European countries. Professional installation is generally required for full home storage operation and full output. In Germany, for example, regulations are increasingly changing to support plug-in operation including charging from the grid, with output limits up to 800 VA, meaning self-installation and self-registration are permitted only to a point.
The retrofit market the company is targeting is more toward large-scale full rooftop solar systems, and all up, the company claims the Solarbank Max AC is the world’s first 7 kWh all-in-one plug-in home storage system.

Solar farm company to hold public meeting before submitting application – Jacksonville Journal-Courier

Nexamp wants to build a solar farm near Prairie Knolls in Jacksonville.
The company Nexamp, which wants to build a solar farm northeast of the Prairie Knolls neighborhood, is inviting Jacksonville residents to an informational meeting about the project.
The discussion will be from 4 to 7 p.m. Tuesday at Twisted Tree Music Hall, 1061 E. Morton Ave.

The project would encompass 15 or 16 acres on the east side of Blacks Lane, south of the train tracks. Jack Curry, Nexamp's director of business development, said company representatives will be on hand to answer any questions people may have.
Nexamp presented this map to Jacksonville City Council in October. It outlines a mockup of a proposed solar farm.
RELATED: Company wants to bring 15 acres of solar panels to Jacksonville
"It's an effort to make sure that folks don't feel blindsided by an application that we submit to the city and all of the sudden there's a public hearing, and maybe folks feel like they weren't a part of the discussion early on," Curry said.

In an October presentation to aldermen, Nexamp said the project could improve its visual aesthetics by offering vegetative screening and a pollinator mix. When the project's lease is up in 20 to 40 years, the land could be rezoned for farm use, the company said.

The solar farm technology on the land at that point would be recycled through its partnership with We Recycle Solar, the company said.
The city's recently passed ordinance regulating battery storage would not affect the project because it does not have battery storage, Curry said. The ordinance dictates how and where companies can use battery energy storage systems as a way to have more control over energy projects. It passed second reading on March 23.
RELATED: Jacksonville ordinance would regulate solar panel projects
The last major solar project built in Morgan County is the Double Black Diamond project, which supplies electricity to Chicago. The proposed project is much smaller — about 16 acres compared to more than 4,000 acres, Curry said.

"It is considerably smaller than maybe the type of project that they saw previously back in 2024, and I think there are probably some lessons learned based on what I've read about that project," Curry said. "And we've made an effort to shrink the size of our project. No. 1: Set it back as far as we can from Prairie Knolls; and then also to add quite a bit of vegetative screening to maybe offset some of the view shed impacts that folks are worried about."
RELATED: 2 mobile home parks see new owner after bankruptcy
Curry asked city council in October to make an exception to its rule that solar farms be built 1,000 feet from city limits. He also predicted that about 50% of Jacksonville residents would be allowed to subscribe to projects like this one before the subscription meets its cap.

The company will submit its application to the city in the days following its public meeting, Curry said Tuesday.
"The goal would be to get on the planning and zoning commission within the next few months, depending on their availability to get us on an agenda," Curry said.

UK approves Britain’s largest power-producing solar farm – Engineering and Technology Magazine

Shutterstock
The 800MW Springwell Solar Farm has been granted approval as Britain breaks the solar power generation record with the sunny spring weather.
Located on land between Lincoln and Sleaford, once complete in 2029 the vast Springwell Solar project will export enough renewable electricity to the grid to power over 180,000 homes a year. This is the equivalent of half the homes in Lincolnshire.
This news comes as the UK officially breaks its record for the amount of power generated from solar farms across the country. On Monday 14.1GW of low-carbon electricity was generated at lunchtime, surpassing the previous high of 14GW in July 2025. This record was then broken the very next day with a new high of 14.4GW on Tuesday afternoon.
Jointly owned by EDF Power Solutions UK, a subsidiary of French energy firm EDF Group, and solar developer Luminous Energy, the Springwell Solar Farm will now proceed towards construction following the Development Consent Order granted by the government. 
Springwell is classified as a Nationally Significant Infrastructure Project because of its generating capacity (over 100MW), and marks the 25th such project approved by the government since July 2024. Together, these could generate enough electricity to power the equivalent of up to 12.5 million homes.
The government is on a mission to decarbonise the UK’s grid by 2030 through solar and wind power, and avoid the country being held at the mercy of volatile fossil fuel markets. While projects such as Springwell require large areas of land, the government hopes the clean power they generate will win over the public by delivering greater stability and lower energy bills. 
Energy minister Michael Shanks said: “It is crucial we learn the lessons of the conflict in the Middle East – solar is one of the cheapest forms of power available and is how we get off the rollercoaster of international fossil fuel markets and secure our own energy independence.”
However, placing such infrastructure in the countryside has not been without criticism. Local Lincolnshire campaign groups have been fighting the project’s application since it was submitted in November 2024, arguing that it poses risks to the local community, wildlife and national food security. The approval for Springwell also comes six months after the government backed Tillbridge Solar Farm, another vast solar farm in the county.
Following a period of examination and consultation with local communities and other stakeholders as part of the application process, the plans for the Springwell project were scaled back, reducing the total site area from around 4,200 acres to about 3,163 acres.
In a bid to address concerns from local residents about the impact of the project, EDF Power Solutions UK said it will include 12km of new footpaths, more than 15km of new hedgerows and a community growing area for public use. A community benefit fund would also provide £400 per megawatt of installed capacity to support local projects.
Matthew Boulton, EDF Power Solutions UK’s director of storage, solar and private wire, said: “As the project moves forward, we remain committed to working collaboratively with local communities and partners to reduce the impacts of construction while delivering long-term benefits for the region.” 
Last month, the government announced new building regulations that will make it mandatory for most new homes built from 2028 to include on-site renewables, mainly rooftop solar, along with low-carbon heating such as heat pumps and heat networks. As part of this, it has also streamlined plans to roll out low-cost, portable ‘plug-in’ solar panels to generate electricity for a home’s electrical system. 
In the meantime, Offshore Energies UK has called on the government to allow UK domestic oil and gas production in the North Sea to continue alongside the expansion of offshore wind capacity to secure energy supply. 
However, a recent report from the Smith School of Enterprise and the Environment found that draining the North Sea of all oil and gas would cost households more than a fully renewable-powered UK. Its analysis found that much larger savings would be gained from staying the course on clean energy.

Watch: Silicon Ranch holds public meeting to address Stockton solar farm concerns – 1819 News

BAY MINETTE — The developers of a proposed solar facility in Stockton met with community members on Wednesday to discuss plans for the 4,500-acre site.
Dozens of demonstrators showed up with signs and lined D'Olive Street in front of the John R. Rhodes Civic Center, where the meeting was held. They wanted to show Silicon Ranch that they are passionate about protecting the area's natural resources.
Silicon Ranch CEO Reagan Farr presented information on how the company's utility infrastructure is used. He said that with power companies experiencing record growth, they need more generation to feed the power grid.
"I will say, we as a country have come to expect reliable, reasonably priced power, and we've never had to choose between economic development and reliable, affordable power," said Farr. "We are going to have to start making that decision. And we really need, as a country, to be investing in generation."
Since Silicon Ranch began, he said the company has aimed to improve soil health, promote biodiversity and enhance wildlife on properties. They call the practice of regenerative energy and agriculture "agrivoltaics."
Silicon Ranch plans include 2,500 acres of wetlands and buffers. Loran Shallenberger, the vice president of regenerative energy and agrivoltaics at Silicon Ranch, said the company owns the largest flock of sheep in the Southeast and plans to incorporate cattle in its Stockton site.
SEE ALSO: Silicon Ranch defends Stockton solar project despite grassroots effort to shut it down
The Baldwin County Commission approved a referendum to allow voters to weigh in on zoning in Planning District 3. However, Farr said he expects all applications to be submitted before that measure would impact the Stockton project.
The Alabama Legislature considered a bill that would give coastal counties more authority over solar development, but it will likely die as lawmakers run out of time this legislative session.  
Silicon Ranch took questions from concerned citizens during Wednesday's meeting.
RELATED: 'They underestimated Stockton': Hundreds show up to oppose solar farm proposal
The land is currently zoned for industrial use. Farr said his company's use of the land will be more beneficial than the plantation pine timber track it is currently on and more beneficial than most other industries. He presented ways Silicon Ranch benefits conservation, but the opposition accused the company of "greenwashing" to make money.
Silicon Ranch is already contracted with Alabama Power to deliver power by the end of 2028. Farr said he expected the $350 million investment to be successful despite many challenges.
Concerned citizens emphasized their difficulty trusting Silicon Ranch because they did not hear about the project until plans were already underway. Farr said he regrets that the project came to the public's attention after the Public Service Commission approved it and before Silicon Ranch signed a contract with Alabama Power.

Solar Module UV Map Reveals Underestimated Degradation, Risks to New Technologies – News and Statistics – IndexBox

We use cookies to improve your experience and for marketing. Read our cookie policy or manage cookies.
Search across reports, market insights, and blog stories.
Researchers at the University of New South Wales have created the first comprehensive global model of ultraviolet radiation exposure for solar installations. According to the source, this work indicates current industry testing standards might be dramatically underestimating real-world UV exposure, which could shorten the operational life of newer solar technologies by as much as ten years.
The high-precision model calculates UV radiation levels solar modules receive worldwide, factoring in climate, atmospheric conditions, and mounting setup. Published in a photovoltaics journal, it offers the first global comparison of UV exposure for fixed-tilt and sun-tracking solar systems, providing a new method to predict long-term performance and durability based on local environmental factors.
Historically, a comprehensive method for estimating UV radiation on solar panels at specific locations, especially for tilted or tracked installations, has been unavailable. Most global UV data is collected from horizontal surfaces, which does not match typical installation conditions. The new modeling approach incorporates local atmospheric inputs like clouds and aerosols to allow for site-specific assessments.
The model’s validation used precise UV-measuring instruments in Europe and long-term climate data. It provides manufacturers and developers with a holistic overview of expected UV radiation by location without requiring extensive background calculations.
The research is particularly significant as the solar industry adopts advanced high-efficiency technologies designed to use a broader solar spectrum, including ultraviolet light. While these newer cell architectures aim for improved efficiency by harnessing UV radiation, this may lead to unintended long-term reliability issues, with recent studies noting UV sensitivity in some next-generation designs.
The findings show that modules with identical technology and orientation can still degrade at different rates depending on the region due to local weather and climate influences. This underscores a need for climate-specific indoor testing and accelerated reliability assessments. In areas with high UV levels, UV photodegradation alone may cause nearly a quarter of the total annual degradation in certain silicon modules, potentially reducing system lifetime by seven to ten years.
A key finding concerns solar modules on tracking systems, which follow the sun to maximize energy capture. These installations are exposed to substantially more UV radiation than fixed-tilt systems, leading to accelerated degradation pathways not fully captured by current testing standards. In high-irradiance regions, UV-related degradation for such tracking systems could reach a specific annual percentage from UV exposure alone, accumulating significantly over a project’s lifespan.
While manufacturers often quote overall annual degradation rates assuming a steady linear decline, the study suggests degradation may not be strictly linear. UV exposure could account for a significant portion of total performance loss, especially in high-irradiance environments where atmospheric conditions concentrate ultraviolet radiation on panels.
The economic and warranty implications are direct, as prior research has indicated a portion of solar modules degrade faster than average. The global UV map helps identify geographic regions and mounting configurations with the highest risk of accelerated degradation, enabling more accurate financial modeling and warranty risk assessment before deployment.
The research highlights a disconnect between laboratory testing thresholds and actual field conditions. In some high-irradiance locations, modules can receive the entire standard UV test dose within roughly a month of outdoor operation, representing a significant underestimation of real exposure. Consequently, a module might pass a UV test but perform worse in the field due to insufficiently stringent testing protocols.
This issue grows more pressing as modern high-efficiency technologies, some with documented UV sensitivity, become widespread. The fundamental physics of these advanced cell technologies makes them more vulnerable to degradation as they near theoretical performance limits. While atomic-scale self-repair mechanisms in silicon cells can partially offset UV-induced damage, they may be inadequate against the elevated UV doses delivered by tracking systems and high-irradiance locations over decades.
A central conclusion is that UV testing standards need amplification or revision to reflect real-world conditions, especially with the rapid rollout of new high-efficiency photovoltaic technologies. The new modeling tool is designed to help manufacturers, developers, and asset owners make better-informed decisions. Developers could use the global UV map data to conduct more rigorous accelerated UV stress testing on candidate modules before installation, selecting products resilient to the specific UV exposure profile of their intended deployment location and mounting configuration.

The Solar Energy Technologies Office (SETO) supports research and development projects that advance the understanding and use of the semiconductor silicon carbide (SiC). SiC is used in power electronics devices, like inverters, which deliver energy from photovoltaic (PV) arrays to the electric grid, and other applications, like heat exchangers in concentrating solar power (CSP) plants and electric vehicles.
When PV modules generate electricity, energy first flows through a power electronics device that contains a semiconductor. Until around 2011, silicon was the preferred semiconductor used to make these devices, but research has shown that SiC can be smaller, faster, tougher, more efficient, and more cost-effective.
SiC withstands higher temperatures and voltages than silicon, making it a more reliable and versatile inverter component. Inverters convert direct current electricity generated by solar panels from to grid-compatible alternating current. During the conversion process, some energy is lost as heat. State-of-the-art silicon inverters operate at 98% efficiency, whereas SiC inverters can operate at about 99% over wide-ranging power levels and can produce optimal quality frequency. While the 1% increase in efficiency might seem small, it represents a 50% reduction in energy loss. With 60 gigawatts of solar installed in the United States, a 1% increase in efficiency would amount to 600 megawatts of additional solar power each year and cost savings over the device’s lifetime.
Benefits of Silicon Carbide
SiC has an edge over silicon because it enables the following:
The Wide-Bandgap Advantage
One attribute is responsible for these benefits: SiC’s wide bandgap. The bandgap is a measure of energy that signifies the distance between two states—an electron’s starting point in the valence band, which is the nonconduction state, and the level it has to move to in order for electricity to flow. The wide bandgap allows for high voltage, which means SiC can better tolerate voltage spikes, and because devices can be thinner, they perform faster.
Solar and Silicon Carbide Research Directions
Inverters and other power electronics devices are processed on wafers, similar to building integrated circuits on silicon. And just like silicon, as time has progressed, the wafer sizes have increased, making it process more circuits per batch and lowering cost. The cost of a 4-inch wafer dropped by half between 2009 and 2012 thanks in part to fabrication improvements and a higher rate of production. At the same time, sales of SiC devices more than tripled. Around 2015, typical wafer size increased to about 6 inches in diameter.
Now researchers are working to expand the use of SiC to the national grid by developing power electronics devices that link distribution lines to transmission lines. This could potentially do away with huge transformers and save energy. SiC could save energy in other areas, too, especially in electrification of transportation.
In 2017, SETO launched a funding program to examine some of these issues. The Advanced Power Electronics Design for Solar Applications awardees have several projects involving silicon carbide:
Some of these projects focus on making inverters and converters that last longer, work more efficiently, and reduce costs. Others are furthering grid integration by designing devices that can connect with energy storage or load-management devices, detect and respond to abnormal current, or rapidly restore power after an outage. Through this work, SETO aims to develop tools that help grid operators better control solar generation, enable delivery of solar through microgrids, increase grid resiliency, and improve solar reliability for customers. Learn more about our systems integration research.
In addition, three semifinalists in the first round of the American-Made Solar Prize, a competition to revitalize U.S. solar manufacturing, are developing SiC devices: Infineon Technologies America is working on a 1,500-volt converter, BREK Electronics is working on a 250-kilowatt string inverter, and Imagen is working on a three-port high-frequency conversion system.
SiC can also be processed into a ceramic for CSP applications. Such ceramics move heat well. SETO is funding a project team at the University of Utah that’s using SiC to design and develop a stable receiver to absorb sunlight, and researchers at Argonne National Laboratory who are using SiC and the ceramic mullite to create a new heat exchanger through additive manufacturing, or 3-D printing.

The reliability of photovoltaic (PV) systems refers to the ability of these technologies to dependably produce power over a long and predictable service lifetime. The ability to stand up to a variety of weather conditions also contributes to the reliability of these systems. Developing consistent, industry-wide standards to measure reliability in PV systems also facilitates widespread adoption of these technologies.
Research in this topic aims to understand what causes degradation and power loss in PV modules and systems, how their reliability and durability can be improved, and how to ensure high-quality products capable of long lifetimes. Learn more about how PV technology works.
Developing solar products that will last for decades reduces the cost of PV systems by 1) distributing the initial construction costs over a longer timeframe; 2) reducing financing risk by better predicting the evolution of a PV system’s output over its lifetime, and 3) reducing maintenance costs and unforeseen outages that lead to lost revenue. Improving reliability and developing consistent standards is useful for solar manufacturers and developers, financing parties, and engineering, procurement, and construction professionals, as it can help these parties align on lifetime, operations, and maintenance costs, as well as degradation models.
Research in this topic supports the U.S. Department of Energy Solar Energy Technologies Office (SETO) goals of improving the affordability, performance, and value of solar technologies on the grid, and meeting cost targets of $0.02 per kilowatt hour (kWh) for utility-scale PV, $0.04 per kWh for commercial PV, and $0.05 per kWh for residential PV. Learn more about SETO’s goals.
SETO’s research in this topic tackles problems from small to large scale to improve both component and system lifetimes. This includes using data from modules in the field to inform and improve on future system performance. Incorporating lessons learned from operating systems can also reduce uncertainty, which in turn can reduce financing costs. These initiatives support SETO’s overall goals by facilitating the industry to extend system lifetimes up to 50 years. Several of SETO’s funding programs have projects that focus on PV reliability and standards development:

Iconic dome goes green: Science World unveils B.C.’s first vertical solar array as part of major energy efficiency overhaul – BC Hydro

   
VANCOUVER: Nearly four decades after it captured global attention during Expo ’86, Science World is undergoing a major energy overhaul that is reshaping the landmark for a low‑carbon future. In partnership with BC Hydro, the non-profit is in the midst of a $39‑million retrofit designed to significantly reduce the building’s energy use by more than 40 per cent and greenhouse gas emissions by about 75 per cent.
Science World’s retrofit includes three solar arrays – the first-of-its kind vertical installation system in B.C. These 76 panels, in addition to the 298 solar photovoltaic panels, have been added to the roof and will start generating energy before summer. Additionally, aging fixtures are being swapped with LED lighting, new air‑source heat pumps and electric chillers are replacing older heating and cooling systems, and the windows and insulation are also being upgraded to improve efficiency.
“Science World has long been a symbol of innovation in B.C., and now it’s becoming a model for how existing buildings can be transformed for a clean energy future,” said Adrian Dix, Minister of Energy and Climate Solutions. “These upgrades will reduce emissions, lower energy and operating costs, and showcase what’s possible when we invest in energy efficiency.”
The project is supported by $20 million from the Province and $19 million from the Government of Canada’s Green and Inclusive Community Buildings program. BC Hydro worked closely with Science World, providing technical studies, incentives and support for innovative pilot projects including the vertical solar panel system – which will test how the technology performs in low‑sunlight conditions, with the goal of expanding installations to regions across B.C.
Inside the dome, the nearly 800,000 annual visitors will soon be able to watch Science World’s energy transformation in real-time. A new digital display will track solar power generation, building energy use, and – once installed – how battery storage systems are charging and discharging. For Science World’s programming team, it is an opportunity to turn the building itself into an exhibit and show young visitors how clean-energy systems work.
“It’s an exciting time for Science World – and for the province as a whole,” said Tracy Redies, President and CEO of Science World. “With these new upgrades, we’re signalling to our community that we’re invested in building a greener future and that Science World will be here for many more years to come. Together with BC Hydro, we’re showcasing the role of clean energy in a growing British Columbia and inviting visitors to learn more about green technology.”
Some of the most complex work is happening now, as crews install five inches of insulation inside the dome – a massive undertaking that requires specialized scaffolding and a temporary closure of the 400‑seat theatre. Other upgrades, like the LED lighting installed in 2022, have already delivered big results. Despite triple the number of lights, the dome now uses less energy than before.
“Science World is setting a strong example of clean energy leadership, and this partnership reflects BC Hydro’s commitment to helping customers reduce emissions and modernize their buildings,” said Charlotte Mitha, President and CEO of BC Hydro. “We’re proud to support a project that showcases the impact of clean energy technologies in such a visible and engaging way. To recognize Science World’s commitment to energy conservation and sustainability, BC Hydro is pleased to award it the Power Smart Champion designation.”
BC Hydro is accepting nominations from B.C. residents, businesses, municipalities, or Indigenous and community groups that have taken steps to lower their carbon footprint and adopt new clean energy technologies. If you or someone you know is a Power Smart Champion, nominate them at bchydro.com/powersmartchampions.

Best Portable Solar Panels for Camping in 2026: What Works in Real Conditions – Rutland Herald

Partly cloudy skies. Low 38F. Winds SSE at 10 to 15 mph..
Partly cloudy skies. Low 38F. Winds SSE at 10 to 15 mph.
Updated: April 9, 2026 @ 9:43 pm

Camping in 2026 is no longer just about having portable power. It is about how efficiently you can collect usable energy in real outdoor conditions.
A portable solar panel may look strong on paper, but actual performance depends on far more than rated wattage. Sunlight changes throughout the day, campsite orientation is rarely ideal, and setup speed, portability, and charging compatibility all affect how much power you can really collect.
This guide compares several popular portable solar panels based on what matters most in real camping use, including charging efficiency, deployment convenience, durability, and overall practicality.
Unlike controlled testing environments, camping conditions are unpredictable. Sunlight intensity varies depending on time of day, weather, and surroundings.
In real use:
early morning and late afternoon produce lower output

cloud cover reduces charging efficiency

trees, vehicles, or gear can create partial shading
As a result, most portable solar panels operate at roughly 30%–70% of their rated power during a typical day.
The angle of the panel has a direct impact on how much sunlight it captures. A panel placed flat on the ground will always collect less energy compared to one that is properly angled toward the sun.
Panels with adjustable kickstands offer a clear advantage:
better sunlight alignment throughout the day

improved total daily energy collection

more control in different campsite layouts
Even small adjustments can noticeably increase charging efficiency over several hours.
Many users assume that higher wattage automatically means faster charging. In reality, performance depends on several combined factors:
cell efficiency determines how effectively sunlight is converted into electricity

connector type affects compatibility and energy transfer

the connected power station limits input speed
A well-designed 200W panel with higher efficiency can outperform a lower-quality panel with the same rated output, especially when sunlight is limited.
Efficiency plays a critical role in real-world performance. Panels with higher conversion efficiency can generate more usable energy under the same sunlight conditions.
For camping use, panels around or above 20% efficiency provide a noticeable advantage, especially during shorter daylight windows.
Portability is not just about whether a panel can fold. It also includes how easy it is to carry, store, and reposition.
lighter panels are easier to move around camp

compact folded size fits better in vehicles or RV storage

heavier panels may still be practical if they are not moved frequently
Choosing the right balance depends on how often the panel will be handled.
Camping environments often require quick setup. Panels that are easy to unfold and position save time and make better use of available sunlight.
Important factors include:
integrated kickstands

simple unfolding structure

minimal assembly
Faster setup means more time collecting energy.
Solar panels used for camping need to handle real outdoor conditions. This includes exposure to dust, moisture, and uneven terrain.
Features that matter:
splash or water resistance

durable surface materials such as ETFE

stable support structure
A panel that cannot handle outdoor use will quickly lose its practicality.
Compatibility affects how easily a panel integrates into your setup.
MC4 connectors support most solar generators

direct charging ports can be useful for smaller devices

ecosystem compatibility can simplify setup for some users
Choosing the right interface avoids unnecessary limitations.
EcoFlow NextGen 220W Bifacial Portable Solar Panel stands out as one of the most complete options for camping in 2026, especially for users who want to maximize charging efficiency during limited sunlight conditions.
This panel combines a 220W rated output with a bifacial design, allowing it to capture energy not only from direct sunlight but also from reflected light on surfaces such as sand, gravel, or light-colored ground. In real camping scenarios, this additional energy capture can make a meaningful difference over the course of a day.
The panel also reaches up to 25% conversion efficiency, which places it among the higher-performing options in this category. This becomes particularly important when sunlight is not ideal, such as during early morning, late afternoon, or partially cloudy conditions
Another practical advantage is its adjustable 30°–60° kickstand system, which allows users to optimize the panel angle depending on the sun’s position. Combined with its structure, this helps improve total daily energy collection without requiring complex setup.
From a durability perspective, the panel features an IP68 rating, offering strong protection against dust and water exposure. This makes it more suitable for outdoor environments where weather conditions can change quickly.
In real camping and road trip use, this panel is especially useful in situations where:
sunlight hours are limited

users want faster daytime charging

maximizing energy collection is more important than minimizing cost
Compared with traditional single-sided panels, the bifacial structure gives it a clearer advantage in environments where reflected light can be utilized.
Jackery SolarSaga 200W is designed with simplicity and ease of use in mind, making it a practical option for users who prefer a straightforward solar setup.
With a 200W output and up to 25% efficiency, it delivers competitive performance under good sunlight conditions. The foldable design allows for quick deployment, and the overall structure is easy to handle for typical camping use.
One of its more distinctive features is the inclusion of built-in USB-A and USB-C ports, which allow direct charging of small devices such as phones or tablets without needing a separate power station. This can be convenient for short trips or minimal setups.
In real use, SolarSaga 200W works well for:
short camping trips

users who want quick setup without adjustments

charging smaller devices directly
While it does not emphasize advanced structure or ecosystem integration, it provides a reliable and easy-to-use solution for general outdoor charging.
Renogy E.Flex 200W N-Type Portable Solar Panel focuses on balancing efficiency, portability, and flexibility.
It features N-Type solar cells with up to 25% efficiency, which helps improve performance under less-than-ideal sunlight conditions. Compared with older cell types, this design maintains more stable output throughout the day.
Weighing 6.3 kg (13.89 lb), it is lighter than many other 200W panels, making it easier to carry and reposition when needed. This is particularly useful for campers who frequently adjust panel placement to follow sunlight.
The panel also includes:
adjustable kickstands for angle optimization

support for direct charging, batteries, and power stations

IP65 splash and dust resistance for outdoor use
In practical terms, this model is well suited for:
users who move their panel throughout the day

campers who want a balance between power and portability

situations where flexibility and ease of handling matter
BLUETTI PV200 is positioned as a reliable, all-around portable solar panel for general outdoor use. It offers a 200W output with up to 23.4% efficiency, which is slightly lower than some higher-end panels but still within a solid performance range for camping.
One of its key strengths is durability. The panel features an IP67 rating, providing strong protection against dust and water exposure. This makes it suitable for outdoor environments where conditions can be unpredictable, such as beaches, forest campsites, or roadside stops.
It also uses a standard MC4 connector, which ensures compatibility with a wide range of solar generators. This flexibility makes it easier to integrate into different setups without needing specialized adapters.
The adjustable stand system, typically around 45° ± 10°, allows users to improve sunlight capture without adding complexity to setup.
In real camping use, BLUETTI PV200 works well for:
users who need a dependable, weather-resistant panel

setups that require broad compatibility with different power stations

general-purpose outdoor charging without focusing on advanced features
It does not emphasize maximum efficiency or lightweight design, but it provides a stable and practical solution for most standard camping needs.
Goal Zero Nomad 200 takes a slightly different approach, focusing more on storage efficiency than lightweight portability.
With a 200W output, it delivers strong charging capability for larger power stations. Its most distinctive feature is its folding structure, which allows the panel to collapse into a relatively compact size compared to its full deployment footprint.
However, at 10 kg (22 lb), it is one of the heavier options in this category. This makes it less suitable for frequent repositioning, but still practical for setups where the panel is deployed once and left in place for extended periods.
The included 6 ft cable provides some flexibility when positioning the panel relative to your power station, which can be helpful in campsite layouts.
In real use, this panel is best suited for:
road trips or van setups where storage space is limited

users who prioritize compact folded size over carry weight

longer stays where the panel remains stationary
It is not designed for frequent movement, but it works well when used as a stable, higher-output charging source.
ALLPOWERS SP033 stands out primarily because of its price positioning. It offers a 200W rated output with 19%–22% efficiency, which is lower than some competing models but still usable for general camping scenarios.
The panel uses a monocrystalline cell structure and a standard foldable design, covering the basic requirements expected from a portable solar panel.
Its main advantage is accessibility:
lower upfront cost

compatible with many solar generators

simple structure with no complex setup requirements
In real-world use, this panel works best for:
budget-conscious users entering the 200W category

occasional camping rather than frequent heavy use

setups where cost matters more than maximum efficiency
However, because of its lower efficiency range, it relies more heavily on strong sunlight conditions to reach higher output levels.
Understanding real charging speed is critical when choosing a solar panel for camping.
Under strong, direct sunlight around midday, a 200W panel can typically produce:
around 120W to 160W of usable output
This is the closest most users will get to the rated power.
In normal conditions throughout the day:
output usually falls between 80W and 120W
This range is more representative of actual daily performance.
When sunlight is weaker:
output can drop to 20W to 60W
In these situations, panel efficiency and angle adjustment become much more important.
Camping often comes with limited charging windows. You may only have a few strong sunlight hours each day.
That is why:
higher efficiency panels collect more energy in less time

better angle adjustment improves total daily output

faster real charging reduces dependence on backup power
A flat panel cannot capture sunlight efficiently. Even a small angle adjustment can significantly improve output.
Shadows from trees, tents, or vehicles can reduce performance dramatically. Even partial shading affects the entire panel.
Not all panels work equally well with every power station. Connector mismatch or input limits can reduce charging efficiency.
Rated wattage is a maximum value under ideal conditions. Real output fluctuates throughout the day and should be expected to be lower.
Lower-cost panels may save money upfront, but slower charging can result in less usable energy over time.
In real camping conditions, the best portable solar panel is not defined by its rated wattage alone. What matters more is how efficiently it converts sunlight, how well it adapts to changing outdoor conditions, and how much usable energy it can collect during limited daylight hours.
Across different options, some panels focus on affordability, some on simplicity, and others on durability or storage convenience. These differences can meet different user needs, depending on how and where the panel is used.
However, when looking at overall performance as a complete package, including charging efficiency, real-world output, structural design, and adaptability, one option stands out more clearly.
EcoFlow NextGen 220W Bifacial Portable Solar Panel delivers the most balanced and capable performance for camping use.
Its combination of:
220W output

bifacial energy capture

up to 25% efficiency

adjustable 30°–60° angle

IP68-level protection
makes it better suited for real outdoor conditions where sunlight is limited, angles need adjustment, and charging efficiency directly affects how much energy you can store before sunset.
For campers who want to charge faster, collect more energy during the day, and rely less on ideal weather conditions, EcoFlow 220W is the most recommended choice in this comparison.

Solar manufacturers expect demand shift and price increases as AIKO doubles down on R&D – Strategic Energy Europe

Our initiatives

The global photovoltaic market is entering a transition phase after two years of intense competition and declining solar module prices, in a context where the sector is beginning to observe cost pressures linked to raw materials and regulatory changes.
“The cost outlook for 2026 is upward and will be mainly driven by three factors: the price of silver, the increase in silicon, and the cancellation of the 9% export tax rebate as of April 2026. Considering only these three factors, the estimated increase is around +0.20–0.22 CNY/W,” said Guillermo Estébanez, Product Solution Manager Southern Europe Utility at AIKO.
The executive explained that the market has recently reached its lowest point after a prolonged period of price declines. “Over the past two years, module prices dropped drastically due to extreme competition, which in many cases deteriorated margins, but also product quality and raw materials,” he stated in an interview with Energía Estratégica.
“The price of silver rose from 8,000 to 27,000 CNY/kg during 2025, with an estimated impact on the average price of +0.13 to +0.15 CNY/W,” the executive explained.
This scenario is also compounded by fluctuations in silicon prices within the photovoltaic supply chain, another key component in cell manufacturing.
“Every 10,000 CNY per tonne increase in silicon prices translates into a module cost increase of between 0.02 and 0.03 CNY/W,” Estébanez specified.
Likewise, the executive warned that the sector will have to absorb the impact of fiscal changes in China that will affect exporting manufacturers.
“The cancellation of the 9% export tax rebate as of April 2026 will have an estimated impact of +0.05 to +0.06 CNY/W,” he added.
Meanwhile, the European market is going through a phase of moderation in its growth rate after several years of accelerated expansion.
Estébanez noted that, although global demand remains high, the region showed signs of slowdown over the past year. “With between 600 and 650 GW, in 2025, the solar market in the European Union declined slightly compared to 2024,” he indicated.
Specifically, the continent recorded around 65.1 GW installed, representing a slight year-on-year decrease of –0.7%.
According to the executive, this dynamic is mainly due to the reduction of subsidies in some countries and bottlenecks in energy infrastructure, especially in grid connection processes.
“Short-term demand remains moderate, while long-term growth is expected to be steady,” he stated.
Despite this pause in the pace of expansion, the outlook for the European market remains significant. The European Union maintains its target of reaching 750 GW of installed solar capacity by 2030, which will require sustaining a high deployment rate in the coming years.
Within this landscape, Spain continues to position itself as one of the most relevant markets on the continent. The country has set a target of reaching around 76 GW of installed solar capacity by 2030, thus driving the expansion of the renewable energy mix.
Against this backdrop, AIKO is reinforcing its technological strategy through research and development as one of the central pillars of its market positioning.
R&D is one of our main hallmarks,” Estébanez stated.
Currently, more than 20% of the company’s employees work in this area, supported by more than €450 million invested over the past three years and more than 1,000 registered patents.
According to the executive, this approach enables the acceleration of innovation cycles and the optimisation of technology performance. “AIKO is one of the few manufacturers that control the entire value chain, from quartz, polysilicon, wafer, cell, to module,” he highlighted.
Within this framework, the company is developing solutions aimed at improving efficiency and reducing dependence on critical raw materials.
“We started some time ago to develop more reliable, low-cost solutions. One of them is the use of copper instead of silver for metallisation, which not only allows cost reduction, but also ensures supply chain stability and high reliability and conductivity,” he pointed out.
New generations of modules for different segments
In parallel with its R&D strategy, AIKO introduced new generations of modules aimed at different segments of the photovoltaic market, from residential installations to utility-scale projects. Among the new products are the Neostar, Infinite and Stellar series, which incorporate All Back Contact (ABC) technology to maximise light capture and improve panel efficiency.
According to Estébanez, third-generation models introduce improvements in power, efficiency and durability. Among them, the Neostar 3P54 stands out, reaching up to 500 W of power and efficiency close to 25%, while for large-scale plants, the company developed the second generation of Stellar, specifically the Stellar 2N+, with outputs of up to 680 W and bifaciality levels of around 80%. These solutions aim to optimise energy production, reduce electrical losses and improve project performance over their lifetime.
“We are entering an era of value-driven competition, driven by end-user needs. With module efficiency increasing from 21% to 25%, and with prospects of reaching 35% in 15 years, we are focusing on value-driven, customer-centric innovation,” concluded the company’s representative.

China
The largest single photovoltaic project in Southeast Asia, developed by China General Nuclear Power Group (CGN), was connected to the grid for power generation on Tuesday in Laos’ Oudomxay Province, marking a major milestone in the region’s transition to green energy.
The 1-gigawatt (GW) project is Laos’ first large-scale mountain-based solar farm and also the CGN’s first overseas 1‑GW-class clean energy project independently planned and developed.
It is expected to generate 1.65 billion kWh annually, saving about 500,000 tons of standard coal and reducing carbon dioxide emissions by approximately 1.3 million tons per year.
“We have installed around 2.23 million solar panels at this power station. Through the 500-kilovolt China-Laos cross-border transmission line, the station enables power connectivity, providing stable and clean electricity for Laos’ development while supporting regional energy complementarity,” said Wang Yang, head of production and operations at CGN Energy Technology (Laos) Co., Ltd..
As the first phase of a clean energy base being jointly built by China and Laos in the northern part of the country, this project will help transform Laos’ natural advantages into economic strengths, expand cross-border power sharing, and facilitate resource complementarity, market synergy, and industrial collaboration between the two neighbors.
The project has brought together more than 40 Chinese companies from the new energy manufacturing and construction sectors, along with more than 30 Lao firms involved in local construction, machinery supply, and raw material sourcing.
It is reported that the CGN will accelerate the implementation of additional clean energy projects in Laos’ five northern provinces, expand into central and southern markets, and further promote broader connectivity between China and Laos.

China's Low-Carbon Capacity Shifts From Problem to Opportunity – Energy Intelligence

As the fallout of the Mideast war continues to impact oil and gas markets, China’s problem of excess capacity in low-carbon manufacturing — known locally as “involution” — could be flipped into an opportunity, experts say. Across much of the world, interest in clean technologies such as solar panels, batteries and electric vehicles (EVs) has soared — for reasons of energy security, cost or both. Beijing had been grappling with overcapacity in these sectors, but these same industries now face the prospect of increased demand from overseas markets. While it is too early to predict the scale or duration, early data shows a bump in exports — offering a boost to China’s enormous but overcrowded cleantech sectors, at least in the short term.

New global model reveals hidden UV risk for next-generation solar panels – UNSW Sydney

Image from Fotografie-Schmidt/Adobe Stock
Engineers from UNSW have created a worldwide UV radiation map for solar panels, highlighting major differences in exposure depending on climate and mounting systems.
A new global study has revealed that ultraviolet (UV) radiation may be quietly shortening the lifespan of next-generation solar panels by up to 10 years — and current industry testing standards may not fully reflect real-world conditions.
Researchers from UNSW Sydney have developed a high-precision model to calculate how much UV radiation solar panels receive in different parts of the world, depending on climate, atmospheric conditions and mounting configuration.
The work provides the first global-scale comparison of UV exposure for fixed-tilt and sun-tracking solar systems, offering the solar industry a new way to predict long-term performance and durability.
While traditional silicon solar panels primarily rely on visible and infrared light to generate electricity, newer high-efficiency technologies are designed to capture a broader portion of the solar spectrum which includes UV light. 
But that improvement may come with unintended consequences.
The work, led by Dr Shukla Poddar and supervised by Prof. Bram Hoex and A. Prof. Merlinde Kay, with contributions from Dr Phillip Hamer and Mr Shuo Liu, has been published in the IEEE Journal of Photovoltaics.

“Our results highlight that modules with similar technology and orientation can still exhibit region-specific degradation,” the researchers say in the paper.
“This is due to the influence of local weather and climate when exposed to outdoor conditions. This underscores the need for climate-specific indoor testing and accelerated tests for reliability and better lifetime predictions. 
“Notably, UV photodegradation alone can account for nearly a quarter of the total annual degradation in monocrystalline silicon modules in regions with high UV dose, potentially reducing system lifetime by 7-10 years.”
Until now, there has been no comprehensive way to estimate how much UV radiation a solar panel will experience at a given location — particularly once panels are tilted or mounted on tracking systems.
Most global UV data is measured on horizontal surfaces, which does not reflect how panels are actually installed.
“We’ve basically developed a method to quantify the amount of ultraviolet radiation based on different spectral wavelengths, and we’ve produced a global map that shows what you could expect depending on your location,” corresponding author Dr Poddar says. 
“It gives a holistic overview for manufacturers or developers who want to install panels somewhere, without having to do all the background calculations themselves.”
The modelling approach was validated using high-precision UV measuring instruments in Europe and compared against long-term climate datasets.
The model can also incorporate local atmospheric inputs such as clouds, water vapour and aerosols, allowing developers to tailor assessments to specific sites.
One of the study’s key findings is that solar panels mounted on tracking systems — which move throughout the day to follow the sun — are exposed to significantly more UV radiation than fixed-tilt systems.
“For single-axis or double-axis trackers, it’s worse,” Dr Poddar says. “They’re always trying to track the sun to catch the maximum amount of sunlight. That means they’re also getting the maximum UV on top of them, which makes those panels more susceptible and vulnerable.”
In high-irradiance regions, the research indicates that UV-related degradation for single-axis tracking systems could reach around 0.35 per cent per year from UV alone.
“That number might not sound dramatic at first,” she says. “But when you quantify it over 20 years, it accumulates quite quickly.”
Manufacturers typically quote overall degradation rates of around 0.5 per cent per year, often assuming a steady, linear decline. The study suggests degradation may not be strictly linear — and that UV could represent a significant fraction of total performance loss.
Current international standards require solar modules to pass a UV test equivalent to 15 kilowatt-hours per square metre. However, the study shows that in some high-irradiance environments like Alice Springs, Australia, panels may receive that amount of UV in little more than a month.
“It is a significant underestimation of the amount of UV radiation the panels may be exposed to,” Dr Poddar says. “So a module can pass the UV test, but in reality, it could perform much worse because we don’t have sufficiently stringent tests.”
The findings are particularly relevant as modern high-efficiency technologies such as TOPCon and heterojunction cells become more widespread, with some recent industry reports already documenting notable UV sensitivity in certain designs.
“One of the key messages from our paper is that the UV testing standards need to be amplified or changed. With new high-efficiency PV technologies being rolled out so quickly, we need to ensure the standards reflect real-world conditions,” she adds.
The researchers say the new modelling tool is designed to help manufacturers, developers and asset owners make better-informed decisions.
Before installation, developers could use the data to conduct more rigorous accelerated UV stress testing on candidate modules.

Emmvee Photovoltaic Power Ltd Faces Mildly Bearish Momentum Amid Technical Downgrade – Markets Mojo

Technical Trend Shift and Price Action
Over the past week, Emmvee Photovoltaic Power Ltd’s stock price has shown signs of weakening momentum. The previous close of ₹230.20 dropped to ₹223.60, with intraday lows touching ₹222.20 and highs at ₹239.80. This price action, combined with a shift in the technical trend from sideways to mildly bearish, signals a potential correction phase after recent gains. The 52-week high stands at ₹248.35, while the 52-week low is ₹171.50, indicating the stock is trading closer to its upper range but facing resistance.
MACD and Momentum Indicators
The Moving Average Convergence Divergence (MACD) indicator, a key momentum oscillator, currently lacks explicit weekly and monthly signals, but the overall technical summary points to a weakening trend. The absence of a strong MACD crossover suggests that bullish momentum is fading, aligning with the mildly bearish weekly Dow Theory and On-Balance Volume (OBV) signals. These indicators collectively imply that selling volumes are beginning to outweigh buying interest, which could pressure the stock further in the near term.
RSI and Bollinger Bands Analysis
The Relative Strength Index (RSI) on the weekly and monthly charts shows no definitive signal, hovering in a neutral zone. This indicates that the stock is neither overbought nor oversold, leaving room for further downside or consolidation. Meanwhile, Bollinger Bands on the weekly timeframe remain sideways, reflecting limited volatility but a potential squeeze that often precedes a breakout or breakdown. Investors should watch for a decisive move beyond these bands to confirm the next directional trend.
Moving Averages and KST Trends
Daily moving averages have not provided a clear directional cue, but the broader trend is mildly bearish as per the weekly and monthly Know Sure Thing (KST) oscillator readings. The KST, which aggregates multiple rate-of-change indicators, suggests that momentum is decelerating. This aligns with the Dow Theory’s mildly bearish weekly and monthly outlook, reinforcing the notion that the stock may face headwinds in the short to medium term.

Comparative Performance and Market Context
Despite the recent technical softness, Emmvee Photovoltaic Power Ltd has outperformed the broader Sensex index over key periods. The stock delivered a 1-month return of 15.44% compared to the Sensex’s negative 1.72%, and a year-to-date return of 16.28% versus the Sensex’s decline of 8.99%. This outperformance highlights the company’s resilience amid sectoral and market volatility. However, the stock’s Mojo Score of 34.0 and a downgrade from Hold to Sell on 23 March 2026 reflect growing caution among analysts, signalling that the current valuation and momentum may not be sustainable without further positive catalysts.
Volume and On-Balance Volume Insights
The On-Balance Volume (OBV) indicator on the weekly and monthly charts has turned mildly bearish, suggesting that volume trends are not supporting price advances. This divergence between price and volume often precedes a correction or consolidation phase, as it indicates that fewer buyers are participating at higher price levels. Investors should monitor volume patterns closely to gauge whether selling pressure intensifies or if accumulation resumes.
Outlook and Investor Considerations
Given the mildly bearish technical signals and the downgrade in Mojo Grade to Sell, investors should approach Emmvee Photovoltaic Power Ltd with caution. The stock’s current price near ₹223.60 is below recent highs, and the technical indicators suggest a potential pullback or sideways movement in the near term. However, the company’s strong year-to-date returns and outperformance relative to the Sensex indicate underlying operational strengths that could support a recovery if market conditions improve.

Sector and Industry Context
Operating within the Other Electrical Equipment sector, Emmvee Photovoltaic Power Ltd faces competitive pressures and technological shifts that influence investor sentiment. The sector’s performance often correlates with broader industrial demand and renewable energy trends. While Emmvee’s recent returns have been robust, the technical indicators suggest that the stock is currently undergoing a phase of consolidation or mild correction, which is typical in cyclical sectors after strong rallies.
Summary of Technical Ratings and Market Position
The downgrade in Mojo Grade from Hold to Sell on 23 March 2026, accompanied by a Mojo Score of 34.0, reflects a cautious stance from analysts. The small-cap classification adds an element of volatility and risk, which is evident in the recent 2.87% day decline. Investors should weigh these technical signals alongside fundamental factors and sector dynamics before making allocation decisions.
Conclusion
Emmvee Photovoltaic Power Ltd’s recent technical parameter changes highlight a shift towards a mildly bearish momentum, with key indicators such as MACD, OBV, and Dow Theory signalling caution. While the stock has demonstrated strong returns relative to the Sensex, the downgrade in analyst ratings and technical signals suggest that investors should monitor price action closely for confirmation of trend direction. A sustained break below support levels or increased selling volume could signal further downside, whereas stabilisation near current levels might offer a base for renewed strength.

The Aristotle University of Thessaloniki, together with Grant Thornton, conducted a study on behalf of the Independent Transmission Operator (IPTO or ADMIE). Professor Pantelis Biskas said this week during the Power & Gas Forum in Athens that one of the most important goals was to determine the optimal storage capacity, while keeping in mind system costs.
The first battery storage facilities are making their entrance into the Greek energy market. The country’s goal is to install upwards of 4.3 GW by the end of this decade, although the sector expects something closer to 4 GW. At the same time, 15 GW to 16 GW of photovoltaics is expected to operate.
Natural gas to become commercially unsustainable
Biskas revealed that the best scenario for storage is 37.5 GWh. This keeps the cost of developing storage to acceptable levels, while providing coverage for many hours each day. On the contrary, if Greece wanted to cover 97% of its needs exclusively through the combination of solar and storage, it would raise the levelized cost of energy (LCOE) to levels equal to natural gas units.
It was also mentioned that, as a result of the mass introduction of storage, natural gas plants would become commercially unsustainable. Therefore, the introduction of a capacity mechanism to support their availability is among possible solutions.
As things stand right now, storage investments are vastly profitable, since the daily arbitrage between the lowest and highest wholesale power price stands at about EUR 200 per MWh. However, their gradual growth is expected to reduce margins and it is uncertain whether later projects will be sustainable.
Aurora Energy Research said that risk management will be essential from now on. Tools such as tolling agreements, day-ahead spread swaps and hybrid power purchase agreements (PPAs) can improve project financing.

Global investment in data center infrastructure reached $1,086 (USD 770 billion) in 2025, surpassing upstream oil and gas spending and reaching levels comparable to the broader energy sector, according to Rystad Energy.
The analysis highlights a structural shift in global energy investment flows, with data centres emerging as a major new source of demand.
Since 2024, capital expenditure on data centres has exceeded investment in solar, positioning the sector as a capital-intensive asset class with direct implications for power generation, grids, and supply chains.
Rystad said data centre investment is split between IT infrastructure and energy-related systems. Servers and computing hardware account for about 40% of total spending, while energy infrastructure – including cooling systems, power distribution, and thermal management – now represents investment volumes comparable to global PV capex.
The expansion of data centres is also driving additional investment across the energy sector, including power generation, grid infrastructure, and industrial equipment.
This multiplier effect is accelerating at a pace that Rystad said exceeds previous industrial expansion cycles, driven by digitalisation and artificial intelligence (AI).
Large-scale facilities with capacities above 100 MW are becoming the dominant format. These projects require infrastructure-level investment similar to large energy assets, but with significantly shorter timelines for grid connection and commissioning, creating challenges for permitting, grid planning, and equipment availability.
Investment is increasingly concentrated among large technology companies and artificial intelligence developers, mirroring patterns seen in upstream oil and gas, where major firms dominate capital allocation.
Geographically, deployment remains concentrated. The United States accounted for 42% of installed capacity in 2025, roughly double that of China, with India ranking third.
However, Rystad expects broader geographic diversification as power demand from data centres exceeds 10% of national electricity consumption in some markets, creating constraints on grid access, land availability, and infrastructure capacity.
Countries with strong energy resources and stable regulatory frameworks, including Finland, Portugal, and Thailand, are emerging as potential hubs for future data centre investment toward 2030.
Rystad said the impact is already visible across supply chains, with rising demand for equipment such as gas turbines, transformers, and fuel cells supporting growth among original equipment manufacturers.
Artificial intelligence is expected to remain the primary driver of demand in the near to medium term, although Rystad said the market may move toward a more balanced alignment of investment, capacity, and demand as it matures.

BOULDER — The Boulder Jewish Community Center has completed a installation expected to offset about 80% of its electricity use and generate nearly $1.8 million in lifetime savings, according to project partners.

The 306-kilowatt system, completed in late 2025 in partnership with Namaste Solar, includes 614 panels and expands an existing 67-kilowatt array at the center’s campus on Oreg Avenue.
Project funding included a $523,143 grant from the city of Boulder’s Community Culture, Resilience and Safety Tax program, along with support from ‘s PACE program, Xcel Energy Solar Rewards, a loan from the Adamah Climate Action Fund and private donations. Federal incentives also helped offset costs.
The project is expected to generate about $1.424 million in utility savings over 30 years and about $374,000 in renewable energy credit revenue over 20 years.
“Sustainability is woven into the fabric of the Boulder JCC,” said Executive Director Jonathan Lev. “This allows us to lead by example while ensuring that our operational savings go directly toward our programming.”
The installation also supported local employment, with 31 Namaste Solar workers contributing to the project, including engineers, designers and installers.
The Boulder JCC campus includes a LEED-certified main building and a net-zero farm that generates all its energy on-site. The organization has signed a five-year operations and maintenance agreement with Namaste Solar to support long-term system performance.

Jacareí advances with a photovoltaic plant and bets on sustainability to transform public management with clean solar energy, reducing operational costs and strengthening energy efficiency in essential services. – CPG Click Petróleo e Gás

Solar Energy
Jacareí has initiated a strategic project aimed at changing the way public administration consumes energy. The implementation of a photovoltaic plant represents an advance in sustainability and efficient management, with a direct impact on municipal finances.
With an estimated investment of R$ 7.8 million, the initiative anticipates an annual savings of at least R$ 1.5 million. This amount, although dependent on the system’s performance over time, indicates the potential for reducing expenses on electricity, one of the most relevant fixed costs for any municipality.
According to the city hall, the construction is already in the earthworks phase and is part of a set of actions aimed at modernizing public management. The expectation is that the system will start operating by 2026, reinforcing Jacareí’s role as a city aligned with new demands for sustainability and energy efficiency.
Maricá transforms Risca-Faca into Leonel Brizola Neighborhood with solar energy and promises to reduce costs for families while promoting dignity, urbanization, and social development in a historically vulnerable community.
The future of the electrical grid: How Virtual Power Plants (VPPs) are revolutionizing the monetization of solar energy and creating new income sources for consumers in 2026.
Revolution in the electric sector: ANEEL approves the operation of the first BESS project co-located with a solar plant in Brazil to stabilize the grid and optimize renewable generation in 2026.
Sustainable culture in motion: Cine Céu travels through Brazilian cities and promotes free and clean entertainment through the use of solar-powered cinema.
The photovoltaic plant is being installed on a public land of approximately 19,000 square meters, located along the Geraldo Scavone Highway. Before the start of construction, the project went through essential stages, such as environmental licensing, land clearing, and area preparation.
The system operates through the photovoltaic effect, a technology that allows the conversion of sunlight into electrical energy. Solar panels capture solar radiation and convert it into usable electricity.
The maximum expected capacity for the plant is 1 MWp (megawatt-peak). In practice, this means that the generated energy can be converted into energy credits, which will be used to offset the consumption of different public units.
Among the main anticipated uses are:
This model allows for a more intelligent management of consumption, making solar energy a strategic asset within the public administration of Jacareí.
The adoption of a photovoltaic plant strengthens Jacareí’s commitment to sustainability. More than just an economic solution, the project represents a paradigm shift in how the municipality deals with natural resources.
Solar energy is a clean and renewable source that does not generate greenhouse gas emissions during its production. This directly contributes to reducing environmental impact and meeting global decarbonization goals.
According to the International Energy Agency, the expansion of solar energy has been one of the main drivers of the global energy transition, especially in countries seeking more sustainable alternatives.
By investing in sustainability, Jacareí not only reduces costs but also improves its institutional image and positions itself as a city committed to the future.
One of the most relevant points of the project is the positive financial impact on public coffers. The estimated savings of at least R$ 1.5 million per year can represent a significant difference in the municipal budget over time.
This reduction occurs because the energy generated by the photovoltaic plant decreases dependence on the conventional power grid. As a result, the administration will spend less on energy tariffs, which tend to undergo frequent adjustments.
In addition to direct savings, there are other important benefits:
Energy efficiency is also enhanced, as consumption is offset strategically. This allows for a more balanced and sustainable management of public resources.
The implementation of the photovoltaic plant also reflects a more modern and integrated urban planning. The choice of land, with about 19,000 square meters, demonstrates the intelligent use of public areas for structuring projects.
The investment of R$ 7.8 million should not be viewed merely as a cost, but as a long-term investment. Solar energy systems typically have a long lifespan and require low maintenance, which enhances the return over the years.
Moreover, the project contributes to:
This approach reinforces Jacareí’s role as a city that seeks innovative solutions to traditional challenges, such as the high cost of energy.
The project follows a structured timeline, with completed stages and others underway. So far, environmental licensing, land clearing, and area preparation have been carried out.
The current earthworks phase marks the effective start of physical construction. Next, the solar panels will be installed, and necessary tests will be conducted to ensure the proper functioning of the system.
The expectation is that the photovoltaic plant will begin operations by 2026. When fully operational, the structure will have the capacity to generate enough energy to offset a significant portion of the public administration’s consumption.
This advancement consolidates solar energy as a permanent public policy in Jacareí, with benefits that are expected to extend for many years.
The implementation of the photovoltaic plant represents more than just an infrastructure project. It is a strategic decision that combines sustainability, innovation, and fiscal responsibility.
By investing in solar energy, Jacareí transforms a recurring cost into an opportunity for savings and efficiency. The expectation of saving at least R$ 1.5 million per year reinforces the direct impact of the initiative on public management.
Furthermore, the project helps reduce environmental impacts, improve the use of public resources, and strengthen the municipality’s energy autonomy.
With this initiative, Jacareí demonstrates that it is possible to align urban development, sustainability, and energy efficiency in a practical and consistent manner, serving as a reference for other Brazilian cities seeking intelligent solutions for the future.

Ed Miliband slaps 'Chernobyl' solar farm in UK village with locals left outraged – Daily Express

Labour Party Conference 2024 - Day TwoEd Miliband has approved Britain’s biggest solar farm despite the objections of locals who compared it to Chernobyl. The Energy Secretary has ruled against the opposition of locals in Lincolnshire to wave through the development on the basis that it is “nationally significant”.
The Springwell Solar Farm is set to be the largest power-producing solar farm in the UK – according to the developer it could power over 180,000 homes a year, the equivalent of half the homes in Lincolnshire. Residents have bemoaned the impact the development will have on local farming, with the farm set to cover seven square miles of open space with solar panels, impacting 10 villages and thousands of residents.
Local Conservative councillor Rob Kendrick said: “There are no beneficiaries in terms of the people of Lincolnshire.

READ MORE: ‘Rachel Reeves can talk growth all she wants – one man stands in way of glory’ Solar panels fields on the green hills“The landscape will be changed. Tourism is worth £2bn to Lincolnshire and that will be impacted.”
The decision marks the 25th nationally significant clean energy project approved by the government since July 2024 – enough clean energy to power the equivalent of more than 12.5 million homes.
In 2024, Labour scrapped planning rules that previously blocked the construction of new solar farms on food-producing land.
Mr Miliband also designated large solar and wind farms as “nationally significant” schemes that planners should approve by default.
Local officials have accused Mr Milliband of having “made up his mind already” and being disinterested in the fears of those affected.
Marc Williams, of the Springwell Solar Farm Action Group, told Lincolnshire Live in May last year: “The community are so concerned about this…Everyone’s against it, apart from those who will profit.
“We wouldn’t object to plans for a couple of hundred acres but this is vast. It will be an industrialised complex like Chernobyl.
“People will go for a drive and see nothing but panels.”COP29 UNFCCC Climate Conference In BakuEnergy Minister Michael Shanks said: “We are driving further and faster for clean homegrown power that we control to protect the British people and bring down bills for good.
“It is crucial we learn the lessons of the conflict in the Middle East – solar is one of the cheapest forms of power available and is how we get off the rollercoaster of international fossil fuel markets and secure our own energy independence.”
In response to the decision, Mr Williams said: “I’m fuming.
“It shows a complete lack of democratic accountability in this country.”
He added that Energy Secretary Ed Miliband had “taken no account of the local views of people and he’s just ridden roughshod across the community and will basically destroy approximately 4,000 acres just in this area alone”.
Matthew Boulton from EDF welcomed the government approval describing it as “an important step forward for Springwell Solar Farm”.
“I would like to thank everyone who took part in the public examination process and consultations,” he said.

Solar panels on facades: China’s proposal that promises to reduce energy consumption by 80% – Noticias Ambientales

Recibe las noticias más leídas de la semana directamente en tu email
Respetamos tu privacidad. Puedes darte de baja en cualquier momento.

Researchers from the Chinese Academy of Sciences have proposed installing solar panels on building facades, a strategy that could reduce energy costs by more than 80% and mitigate the urban heat island effect in large cities.
The study, published in Nature, highlights that the vertical surfaces of urban environments are underutilized and could become massive sources of clean energy.
The proposal, led by Yao Ling, estimates that the installation of solar panels on facades could generate up to 732.5 TWh per year, equivalent to the electricity consumption of entire countries. Additionally, an average savings of 8.1% in building electricity consumption is calculated, thanks to reduced cooling demand and lower impact of direct solar radiation.
This system would not only produce energy but also serve as a protective layer against the sun, lowering the interior temperature of buildings and reducing the need for air conditioning in summer.
If deployed on a large scale by mid-century, the proposal could reduce up to 37.7 gigatons of CO², significantly contributing to the fight against climate change.
The study emphasizes that facade-integrated photovoltaic (FIPV) energy is a still underexplored opportunity to improve urban climate resilience.
Some cities like Singapore and Hong Kong already have buildings that integrate energy-active facades, while in Europe, experiments with photovoltaic glass are replacing conventional glass. However, challenges persist such as investment cost, architectural and regulatory complexity, and integration with electrical grids.
China is the world leader in solar energy, with more than 80% of solar panel manufacturing capacity and an installed capacity that exceeded 800 GW in 2024. In that year, the country installed more renewable energy than the rest of the world combined, reaching nearly 887,000 million watts in panels, multiplying the capacity of the United States by five.
Solar energy is the backbone of China’s energy transition, helping to meet decarbonization goals, reduce coal dependency, and strengthen national energy security. Innovations such as floating solar plants in reservoirs and coastal areas demonstrate how the country seeks to overcome land limitations and bring energy closer to consumption centers.
The installation of solar panels on facades represents a dual solution: producing clean energy and reducing energy consumption in cities increasingly affected by extreme heat. With China’s leadership in the solar industry and the global potential of this technology, the proposal could become a key pillar of urban sustainability in the coming decades.

Plan for 1,200 solar panels on Manx National Sport Centre roof – BBC

Plans have been submitted for the installation of 1,200 solar panels on the roof of the Isle of Man's National Sports Centre (NSC).
The move forms part of wider plans by Manx Utilities to generate 75% of the island's electricity through solar and onshore wind projects, backed by the government in early 2023.
If the plans are approved, the solar panels on the NSC in Douglas would have a capacity to generate 735 kW of electricity, enough to power hundreds of homes.
Manx Utilities said it formed part of a wider programme "to support the island's transition to cleaner energy, reduce reliance on imported electricity and deliver practical early renewable generation at public buildings".
The submission follows "detailed structural and technical assessments of the NSC roof to ensure the installation meets all safety, design and performance requirements," a Manx Utilities spokesperson said.
A certificate of lawful development, which does not require planning approval, has also been submitted in case the plans are not given the go-ahead, which would see the solar panels generate less electricity at 650 kW.
Manx Utilities said that via either route, the plans would progress, however it was preferred that the proposals were approved as it would allow for more electricity to be generated.
Further updates would be provided as the application progressed through the planning process, it continued.
The plans form part of a wider island strategy to generate 10 MW of solar energy.
Manx Utilities is also in the process of exploring options for installing ground-mounted solar panels in Balladoole, Ramsey, and a floating solar array in Sulby Reservoir.
Read more stories from the Isle of Man on the BBC, watch BBC North West Tonight on BBC iPlayer and follow BBC Isle of Man on Facebook and X.
The funding will create 400 new jobs in green technology at ITM Power in Sheffield.
Douglas Council will introduce the new body made up of 12 young people in September.
Six sailings between the Isle of Man and Liverpool and Lancashire are at risk of cancellation.
Some 40 broadleaf trees are planted to replace "unsafe" older trees in a housing estate.
Smile Dental says a temporary location provided by Manx Care during hospital works is "unsuitable".

Tour highlights solar’s success in Routt, Moffat counties – Steamboat Pilot

NewsNews |

In celebration of more than four years of successful energy production and electricity cost savings, municipal staff members, construction partners and community members gathered Tuesday for a multi-stop Yampa Valley Solar Corridor Tour.
Led by energy services company McKinstry and nonprofit Colorado Public Interest Research (CoPIRG) Foundation, tour speakers outlined how the commercial-scale solar installations at 13 public locations across Moffat and Routt counties have so far provided more than $1.34 million in electricity bill savings.
“We want to celebrate these projects and also lift them up as examples,” said Kirsten Schatz with CoPIRG, a statewide consumer advocacy group that stands up for the public interest in health, safety and well-being matters. “We want to see more projects like these in Colorado, and plant some seeds in other communities.”
From Craig to Steamboat Springs and Yampa, the installations, mostly built on vacant land adjacent to high electric-use facilities, utilize the sun’s rays to produce electricity through a combined 2,266 kilowatt capacity. The large ground-mounted systems or installations on roofs have created operational savings for a variety of city, county and school facilities.
Roy Tipton, former Moffat County director of development services and now an independent consultant, said that the 207kW solar array at the Moffat County Courthouse saves the county at least $30,000 per year in avoided energy costs. Tipton said the array on the east side of the courthouse was paid for upfront through grants and now covers at least 40% of the courthouse’s electricity needs, including the largest electric cost — air conditioning.
Carl Ray, Craig water and wastewater director, said production of the combined 465kW solar installations at the city’s water and sewer plants benefit customers by helping to keep rates under control. Ray said processing plants use a large amount of energy and that the solar field performance “has been as good or better than expected.”
“Any revenue that we can save, that savings is passed along to our customers,” Ray said. “It’s a very important project to offset some of our energy usage.”
All but one of the 13 solar projects at the public facilities shepherded by McKinstry were completed in November or December 2021. The fenced-in solar array at the Moffat County Courthouse was completed in August 2023.
The initial solar projects in 2021 cover portions of electricity needs for the Moffat County Safety Center, Moffat County High School, Craig Water Treatment Plant, Hayden Police Station, Hayden Community Center, Steamboat Transit, town halls in Oak Creek and Yampa, Yampa Valley Regional Airport, and wastewater treatment plants for Craig, Hayden and Steamboat Springs.
The 13 solar projects so far have produced enough energy to power about 1,660 average Colorado homes for one year and have avoided large amounts of harmful air pollution including 24.9 million pounds of carbon dioxide, according to McKinstry and CoPIRG.
The solar celebration tour started in a field of ground-mounted solar panels east of the Yampa Valley Electric Association office in Craig. Completed in late 2023 by energy company Ameresco, that solar array spans 20 acres and has generated more than 22.5 million kilowatt-hours of energy since its completion, an amount that can power more than 2,100 average American homes for one year, Schatz said.
The success of the solar arrays in Moffat and Routt counties show why other Colorado communities should pursue solar before federal tax credits expire in 2027, Schatz said, and how other projects starting soon could be considered as a “safe harbor” for incentives for up to four years.
“The window for federal tax credits for commercial-scale solar installations is starting to close,” said Martin Beggs, McKinstry renewable energy project director. “Communities that act quickly can still secure federal funding covering 30% or more of the total cost for their solar projects.”
The federal Investment Tax Credit for solar allows nonprofit organizations and public entities to receive funding through direct payments.
Ashley Brasovan, McKinstry senior energy account executive, explained how the 13 solar installations were offset in construction costs through $2.1 million in energy impacts funds through the Colorado Department of Local Affairs, which brought the project payback timeframe to 11 years. Commercial solar arrays have an average 30-year lifespan before panels need to be replaced, Beggs said.
“Some stakeholders paid cash and are pocketing all savings, while others financed the arrays and are paying back through the energy savings,” Brasovan explained.
Brasovan said some public entities in Colorado working to install their own renewable energy projects are now investigating geothermal and battery storage options that have federal tax incentives extending through 2032.
She explained that many electric co-operatives outside of Xcel Energy have aligned with the state-allowed net-metering commercial solar cap per meter of 25kW. Many of the existing 13 arrays were built at an advantageous time to construct larger sizes for efficiency, and only the Oak Creek and Yampa town hall installations are small enough to land under the current caps.
Experts on the tour said construction of cost-effective. commercial-scale solar projects are now less financially feasible within the Yampa Valley Electric Association territory with the current 25kW-per-meter commercial net-metering cap, which was downsized by YVEA co-op leadership from a previous 150kW per meter cap in November 2022. Smaller projects are more expensive per installed watt than a large solar field, the experts explained.
“The real challenge is, reducing that to 25kW means you’re never going to see another commercial field like this,” Tipton said standing at the courthouse array. “Because, for us, 25kW isn’t worth doing.”
Schatz remains positive about the benefits of solar arrays, especially when coupled with battery storage, particularly considering weather-related power outages and rising utility bills.  
“We should be doing as much as we can to take full advantage of the clean, free fuel from the sun,” Schatz said, “and these projects here in the Yampa Valley are excellent examples of that.”

Solar trackers have changed the game for PV generation. But are they cutting panel life short? – Renew Economy

Ultraviolet (UV) rays could knock seven to 10 years off the working life of solar panels in some parts of the top end of Australia, according to new research from the University of New South Wales (UNSW).
UNSW’s Shukla Poddar latest research into UV degradation of solar modules models just how much UV is hitting panels around the world, finding that tilted solar modules in regions with tropical, arid, and semi-arid conditions are more vulnerable. 
Crucially, the new paper, published in IEEE Journal of Photovoltaics, also shows how much more UV modules that tilt to follow the sun are likely to get than those fixed in place. 
And it factors in real-world changes, such as what impact cloud cover has on “scattering” UV radiation and reflected UV from other surfaces. 
UV rays break down materials faster over time than lower energy infrared or visible light, the wavelengths commonly used by solar modules to make electricity.
The new data showing where and under what conditions solar modules will degrade faster should prompt a rethink about what is being installed in those places, Poddar says. 
“If we want to have these super high efficient modules in the future, we need to think about how we are testing these modules, or come up with more climate resistant modules,” Poddar told Renew Economy.
“We might have to start thinking about it a little differently from a manufacturing perspective, and a reliability perspective to make sure we are getting the full lifetime of these modules and we are not wasting money by having to replace them if they fail 10 years earlier than expected.”
Current testing under a standard called IEC 61215 means modules are tested with 15 kilowatt hours per square metre (kWh/m2) of UV “dosage” in the 280–400 nanometre (nm) wavelength range and a module temperature of 60 ± 5°C. 
It’s roughly equal to just 46 days of field exposure in Arizona in the US.
An updated protocol suggests UV stress testing at a 225 kWh/m2 UV dose, but that’s still only equivalent to about two years in Arizona.
“The current [post-manufacturing] testing system that we have right now only accounts for approximately 55 to 60 days that a module will experience when placed in a desert climate,” Poddar told Renew Economy.
Newer technologies Topcon, heterojunction technology (HJT), and passivated emitter rear contact (PERC) are designed to capture a wider range of wavelengths.
But that has also increased their sensitivity to UV and with less than a decade of in-field data to show, models that can more accurately estimate the impact of UV radiation are critical.
In Australia, this is especially so for the top-most parts of the country, where climatic conditions are precisely in the range the paper says could carve seven to ten years of their operational lifetime.
“Northern Australia records degradation up to 0.15 per cent /year – 0.2 per cent /year, depending on the system type,” the authors of the paper wrote, a loss rate of 3-4 per cent over 20 years. 
“This is due to higher temperature, humidity, and irradiation in these areas. Even though regions with arid and semi-arid climate types have lower levels of humidity, they receive higher insolation due to clearer skies and record higher temperatures, which contribute to higher UV photodegradation.”
Panel systems that track the sun are more vulnerable to UV degradation, and not just because they’re catching more rays. 
Clouds and other aerosols can scatter or absorb UV waves, while other surfaces reflect more UV onto tilted panels.
It means that using results generated only from horizontal surfaces in the lab, which don’t account for cloud enhancement or scattering, leads to lifetime predictions that aren’t accurate, the paper shows. 
“The UV irradiance incident on a tilted PV module is composed of direct, diffuse, and reflected UV from the top of the module,” it says.
“We can expect similar modules with different mounting, orientation, and technology to have different UV photodegradation rates. 
“Modules with similar mounting, orientation, and technology can exhibit significantly different degradation rates due to the geographical variability of the UV spectrum.”
What that means is a panel mounted horizontally on a Sydney roof gets 1.4 times more total UV radiation than the same model mounted in New Delhi, because of variations in altitude, ozone, atmospheric constituents, and other factors.
UNSW hopes the model will offer the solar industry a new way to predict long-term performance and durability.
But that picture is somewhat complicated by research published in January – also by UNSW researchers – that show solar modules can self-repair that UV damage.
In addition to creating all kinds of secondary damage that comes with sun-degraded parts, UV breaks down silicon-hydrogen bonds that are essential to making electricity. 
But field tests using ultraviolet Raman spectroscopy proved these bonds can repair themselves in less than 10-20 minutes of “normal” sunlight.
Ziheng Liu, the corresponding author on that study, says it means post-manufacturing testing might be overestimating, not underestimating, the effects of UV on solar panels. 
“This approach helps distinguish between true long-term degradation and reversible changes,” Liu said at the time. 
“That distinction is essential for accurate lifetime prediction.”
