Several manufacturers used KEY 2026 to introduce new module technologies, including JA Solar’s DeepBlue 5.0 TOPCon, Gokin’s AllBlack back-contact, Aiko’s upgraded Infinite ABC and SolarFabrik’s Mono S4 Halfcut BC White module. At the centre of JA Solar’s KEY 2026 showcase was DeepBlue 5.0, the company’s fifth-generation n-type TOPCon technology. The JAM66D50 GB modules deliver up to 670 W in a double-glass bifacial design, making them suited to large commercial and industrial rooftops as well as ground-mounted systems. Due to a completely renewed mechanical design with a different positioning of the junction boxes (Triangular Dispersed Layout), the new module is designed to help reduce mechanical stress on the rear surface, lowering the risk of micro-cracks and breakage even under high mechanical loads, explained JA Solar speaker Gianluca Micheletto in conversation with pv Europe. Over the course of the year, JA Solar also intends to offer back-contact modules alongside its TOPCon technology, Micheletto added. Stay informed – subcribe to our newsletters In the premium residential rooftop segment, the Chinese manufacturer Gokin debuted its new “AllBlack” back-contact module. Featuring a grid-line-free, pure-black surface, it offers seamless architectural integration without sacrificing energy conversion. Hans-Christoph Neidlein Solarfabrik showcased its Mono S4 Halfcut BC White Module (485/490 W) for private and commercial applications. Senior Business Development Manager Ricarda Gutsch told pv Europe that coloured solar modules for the Italian market are planned to launch later this year. Italy is the second most important market in Europe for coloured modules after Germany, primarily due to heritage conservation requirements. The advantage over roof tiles, said Gutsch, is that the modules are easier to install and can also be removed if needed. Hans-Christoph Neidlein Aiko is responding to the trend towards more tracker installations for solar parks. The company presented its upgraded Infinite ABC (all back contact) module, optimised for tracker use and designed to be robust while slightly lighter (665 W, 24.6 percent efficiency, 32.2 kg). Only copper is used for the cell connectors, and the cell design on the rear side has been slightly modified, reported Federico Brunelli, Solutions Europe Director, in conversation with pv Europe. Overall, Aiko sees itself as a specialist in cell manufacturing and a pioneer in technology development, which is why, unlike other major manufacturers, it does not plan to offer an integrated product portfolio with battery storage, said Brunelli.

In summary A California appeals court upheld a 2022 regulatory decision to reduce rooftop solar payments. Environmental groups may appeal to the state Supreme Court. Welcome to CalMatters, the only nonprofit newsroom devoted solely to covering issues that affect all Californians. Sign up for WhatMatters to receive the latest news and commentary on the most important issues in the Golden State. A California appeals court this week sided with state utility regulators in a case seen as crucial to the spread of solar panels on the rooftops of California homes. Three appeals court judges ruled that the California Public Utilities Commission was justified in reducing the rate utilities pay customers for excess energy the customers’ solar panels generate. Environmental advocates who brought the case say the decision will exacerbate California’s energy affordability crisis. Regulators believe it vindicates a decision they took “to ensure that rooftop solar programs remain fair, sustainable, and aligned with California’s clean energy goals,” CPUC spokesperson Terrie Prosper said Tuesday. The case centered on the state’s “net energy metering” program, which governs how much solar customers are paid for excess power from their panels. Earlier versions of the program guaranteed customers the retail rate, which is how much utilities charge other customers when they resell the energy. But a 2022 commission decision reduced this payment by about 75%. The commission’s decision backed utilities’ position, which was that those who have rooftop panels don’t pay their fair share of costs such as maintaining the grid, shifting the expenses disproportionately to non-solar customers. The decision resulted in a significant drop in new customers signing up for rooftop solar. Advocacy groups sued over the decision, including the Center for Biological Diversity, The Protect our Communities Foundation, and the Environmental Working Group. They argued that commissioners didn’t properly take into consideration the benefits to disadvantaged communities and customers of having local energy generation. The case reached an appeals court, which applied, in a decision siding with commissioners, a legal standard granting them significant deference. The Supreme Court of California then unanimously ruled last August that the lower court should not have applied this standard and must delve more deeply into the substance of the arguments.
Roger Lin, senior attorney at the Center for Biological Diversity, said this week’s decision is “disappointing” and the groups are “evaluating all of our options.” They can appeal again to the state supreme court. “The whole reason the utilities created the ‘cost shift’ narrative was to preserve their profits,” Lin said. Under state law, utilities can earn a rate of return on everything they build, which amounts to hundreds of millions of dollars from ratepayers every year. They can’t earn that return on customers’ rooftop solar. The decision comes amid renewed attention on California’s energy affordability crisis. Golden State residents pay the second highest rates in the country for energy after Hawaii, according to the U.S. Energy Information Administration. Ratepayers routinely admonish state utility regulators for their high bills at public meetings. And Gov. Gavin Newsom recently announced an upcoming replacement of the head of the utilities commission as part of a move to focus on bill affordability.

Kärcher aims to build a closed-loop cleaning ecosystem for India’s solar industry, covering both PV manufacturing environments and the long-term maintenance of PV plants. Kärcher Kärcher aims to build a closed-loop cleaning ecosystem for India’s solar industry, covering both PV manufacturing environments and the long-term maintenance of PV plants. “Our goal is to provide a closed-loop cleaning ecosystem for the Indian solar sector,” said Puneet Sharma, managing director of Kärcher India. “From the moment a PV panel is manufactured in a dust-free environment using our KIRA robots, to its 25-year operational life where it is maintained by our iSolar systems, Kärcher aims to ensure that ‘clean’ equals energy efficiency.” PV plant cleaning solutions To maximize energy yield in dusty environments, Kärcher offers modular PV cleaning systems that combine mechanical agitation with controlled water pressure. The company’s iSolar module cleaning solutions are designed to remove dust while minimizing water consumption. The iSolar 400 disc brush has a working width of 400 mm and is suited for small to medium-sized PV installations. Its lightweight design allows operators to clean elevated systems with relative ease. The water-driven iSolar 800 brush head with 800 mm working width works with two contra-rotating disc brushes. The contra-rotation balances transverse forces, enabling operators to guide the unit with limited physical effort during extended cleaning shifts. Unlike conventional pressure washing, the iSolar system uses the water stream primarily to drive the brushes and rinse the surface. The telescopic wand made from a carbon-fiberglass composite extends up to 14 meters, enabling operators to clean entire rows of modules from the ground or from designated walkways. Cleaning solutions for manufacturing facilities With its industrial cleaning solution, Kärcher also targets India’s expanding solar module and battery manufacturing sector, where maintaining dust-free production floors is critical for product quality. Kärcher provides both autonomous and manual floor-cleaning systems for industrial environments. KIRA (Kärcher Intelligent Robotic Applications) series robots are designed for cleaning large production halls and logistics warehouses. Models KIRA B 50 and KIRA CV 50 operate autonomously and are equipped with docking stations where the robot automatically refills fresh water, drains wastewater, and recharges its lithium-ion batteries. “Equipped with LiDAR sensors and 3D cameras, the robots can operate safely alongside human workers and automated guided vehicles, making these ideal for the high-traffic floors of a battery gigafactory,” stated the company.

A majority of new energy added to the grid in the U.S. came from solar installations, according to a new report. Oklahoma’s capacity to generate solar energy jumped significantly last year, more than doubling the number of megawatts it can produce. A report from the Solar Energy Industries Association and research company Wood Mackenzie ranks Oklahoma as 40th for solar capacity. But its analysis shows the state is increasing its investment in the renewable energy source. At the end of 2025, the state’s total solar output reached 842 megawatts, enough to power about 105,000 homes. That number jumped from under 400 megawatts in 2024. More: As demand grows, Oklahoma considers its energy path forward Most of the added generation came from utility-scale solar, the report says, like the Kiowa County Solar Project near Snyder. The project became operational last year, adding 100 megawatts, or enough solar energy to power 21,000 Oklahoma homes annually. Oklahoma’s added generation came online the same year the Trump administration set expirations on federal incentives for some forms of renewable energy, including solar. The One Big Beautiful Bill, signed in July, phases out clean energy tax credits included in or expanded by the Inflation Reduction Act, passed during the Biden administration. Companies have until the end of 2027 to claim the clean energy tax credit. Incentives for residential solar panels were axed at the end of last year. About 1% of Oklahoma homes have solar installations, according to the new report. StateImpact Oklahoma is a partnership of Oklahoma’s public radio stations which relies on contributions from readers and listeners to fulfill its mission of public service to Oklahoma and beyond.
Mar 14, 2026 — Wildlife experts are warning that a rare ecosystem in Jefferson County could be disrupted by a new solar farm. As WWNYTV reports, the habitat is located just outside the village of Chaumont, in the town of Lyme. It’s called an ‘Alvar plant community’ and contains rare plants and offers a home to certain animals. A proposed solar farm by energy company AES would overlap with that ecosystem. According to the Lyme Responsible Solar committee, plans for that solar farm are expected to be submitted to the state this summer. AES did not respond to comment from WWNYTV.

Monday, March 16, 2026 A massive Top End solar and battery proposal has hit the federal environment queue following a bruising, but brief, experience in the legal system. The Wak Wak solar project is looking to combine a 2.7 gigawatt (GW) solar farm and a 6 gigawatt hour (GWh) battery on the Koolpinyah station, a pastoral lease near Humpty Doo and about 48km south of Darwin. The 56-page EPBC referral maps out its potential environmental impact, which includes seven federally-listed birds, animals and reptiles and a range of different landscapes. The developer, TotalEnergies and Eren Group subsidiary TE H2, closed a legal bid last month that sought to declare no native titles exist over the piece of land. It was a move TE H2 said last year was to find the rightful owners rather than cancelling any native title over the property. It scrapped the suit after finding more Indigenous families in the area to negotiate with. The project, which is listed in the referral with an estimated works start date of May 2027, will cover an area up to 3,400 hectares and disturb up to 2,500 hectares of land. TE H2’s original construction timeline started in 2028. Both figures are conservative maximums, the EPBC referral is at pains to say. “The project is currently at concept design stage and the project area (up to 3,400 ha) and disturbance footprint (up to 2,500 ha) have been presented as conservative, rounded-up estimates to define the maximum credible development envelope,” the referral says. “The significant impact assessments for Matters of National Environmental Significance (MNES) have been undertaken using the higher, conservative area estimates.” The massive project will connect to a planned high voltage overhead transmission line that is currently being planned by the Northern Territory government called the Territory Energy Link, running up to the Middle Arm Peninsula industrial hub. TE H2 has a longer term plan to use Wak Wak to power a hydrogen facility in that industrial precinct, so it needs to fit into the link plans. The environmental investigation area took in a bigger area than the patch of land Wak Wak will disturb, covering 5000 hectares. It found seven at-risk creatures across that space: the black-footed tree-rate, bare-rumped sheath-tailed bat, northern blue-tongued skink, northern brushtail possum, Mertens’ water monitor, Mitchell’s water monitor, and the partridge pigeon. And it catalogued a range of landscapes from low hills, savannah-like woodland, and a section that is inside the Adelaide river coastal floodplain. Burn-offs have “severely compromised” the ecological condition of much of the proposed site leading to a reduced midstorey and Gamba Grass infestations, the referral says. “Most of the project area has burnt upwards of 20 times since 2000, but there are areas aligning with watercourses and drainage lines that have burnt less,” it says. “The northern section has also been subject to late season burns of a higher frequency compared to the south, with some areas being subject to late season burns around 12 times since 2000. “The project area was deliberately located in the poorest quality habitat to minimise impacts to biodiversity values and threatened species.” The risk to animals, birds and reptiles comes from the disturbances from construction. The EPBC referral says surveys only found black-footed tree-rats in one spot, and that’s outside the disturbance footprint in the south-west. The bare-rumped, sheath-tailed bat was found in five places on the site including one inside where the project is proposed to be built. Northern blue-tongued skink were found at three disparate locations, one of which is inside the project disturbance area. TE H2 says in the referral the habitat inside the disturbance footprint is “the lowest quality” and wildlife corridors will improve the volume of the kinds of bush the skinks like to live in. Moreover, it doesn’t believe building a solar farm will bring in more cane toads, which are a threat to the skinks. The northern brushtail possum may be more of an issue, as it was found across the Wak Wak site, and the partridge pigeon which was found at eight places inside the lease area. Habitats for the Merten’s and Mitchell’s water monitors are not inside the areas where TE H2 plans to build.

Sign up for email newsletters e-Edition TRENDING: Ransom Twp. argues a proposed solar farm the supervisors rejected last year adversely affects the township and its residents as the developer appeals the supervisors’ denial of the project. In an opposition brief filed last month, then-township Solicitor Kevin Conaboy said residents opposed to the plans presented credible evidence of the adverse effects the project would have on the area and Pivot Energy didn’t provide proof the project would be compatible with township zoning. Conaboy left as the township solicitor earlier this month, Supervisor Chairman David Bird said. The supervisors are expected to appoint William Rinaldi as the solicitor at their meeting next month, he said. The supervisors denied the Denver-based company’s request for conditional use to build 6,550 solar modules on 18 acres of a nearly 300-acre township-owned parcel at Ransom and Lower Narrows roads in June of last year. Residents opposed the proposed solar farm, concerned about its impact on the township’s character, their property values, the environment and wildlife. In their decision, the supervisors said the proposal doesn’t comply with adjoining development, would impact the area’s rural nature and harm property values. They also stated that Pivot failed to provide evidence about the anticipated glare from the facility and how the farm’s potential effects on area properties and public roads would be controlled. Attorneys Richard Williams and Tara Giarratano appealed the decision in Lackawanna County Court shortly after the supervisors’ decision. The attorneys argue that the township and the objectors didn’t present evidence that Pivot didn’t meet the requirements in the zoning ordinance for the proposed conditional use and that the property’s use as a solar farm would substantially affect the community’s health, safety and welfare. They said the supervisors’ decision relied on the objectors’ complaints that the proposed solar farm is incompatible with the area and impacts adjacent properties and property values. Conaboy said in the brief the objectors presented evidence that having a solar farm on the property was incompatible with neighboring development, would impact the rural area, that the project would directly impact the community’s health, welfare and convenience, and would negatively impact property values — all of which violate the township’s zoning ordinance. He also stated the developer didn’t provide evidence concerning the anticipated glare from the facility and how potential nuisance from the project to area properties and public roads would be controlled, which also violates the township’s zoning ordinance. Conaboy said the glare study provided by Pivot Energy failed to take into account all the surrounding properties that would be affected by the project — also required under the zoning ordinance. Conaboy asked the court to deny the developer’s appeal. Copyright 2026 Scranton Times-Tribune. All rights reserved.

California made itself a rooftop solar leader — and now it’s undoing that legacy. Sure, sunny skies have played a big role in getting Californians to install panels at their homes. But for years, the state has also offered hefty incentives to help rooftop solar grow, including net-metering policies, which determine how much utilities pay solar panel owners for sending excess generation back to the grid. Under the first two iterations of California’s net-energy metering policies — NEM1.0, established in the 1990s, and NEM2.0 in 2016 — that power was heavily rewarded. Those big payments for solar power made it easier to recoup the cost of putting up panels — and easier for homeowners to justify their clean investments. Then came NEM3.0. In 2022, California utility regulators approved a plan to slash net-metering payments by as much as 75%. The policy, which went into effect the following year, has seen numerous legal battles ever since. And just this week, a court upheld regulators’ solar-tanking move. The decision comes at a crucial moment for rooftop solar nationwide. After years of setting records, residential solar installations in the U.S. slumped after 2023, falling in both 2024 and 2025, according to a new Solar Energy Industries Association report. Last year’s dip was largely due to economic uncertainty, tariffs, and contractors’ inability to quickly ramp up installations before federal tax credits expired, SEIA said. In the post-incentive new year, some states have increased their own rebates and tax credits to keep clean energy rolling. But with this week’s ruling, California will continue heading in the opposite direction. Recent numbers of total residential solar installations in California suggest what the state’s future under NEM3.0 will look like: Annual installations of residential solar dipped significantly from 2023 to 2024 and remained low in 2025. SEIA expectsNEM3.0 to slow installs even further in 2026. The latest NEM3.0 ruling could be appealed again to the state Supreme Court, and environmental advocates say they’re considering doing so. But as climate journalist Sammy Roth argues, maybe net metering isn’t worth the fight, and advocates should root for new ways to keep solar power growing. Permissionless, plug-and-play balcony solar, anyone? Good news for wind power in the U.S. and beyond Wind power in the U.S. may be riding a roller coaster, but in the rest of the world, the industry is still on an upward climb. A record 169 gigawatts of wind power came online around the globe last year, according to a report out this week from BloombergNEF. More than 100 gigawatts’ worth of those turbines were installed in China, though the rest of the world saw increases as well. There’s also some good wind news to share on the home front. All five under-construction offshore wind farms the Trump administration tried to shut down are set to hit major milestones this month, Canary Media’s Maria Gallucci reports. Off Massachusetts, Vineyard Wind is nearly complete; the Coastal Virginia Offshore Wind project and Rhode Island’s Revolution Wind will soon begin delivering power to the grid; Sunrise Wind is about halfway complete; and New York’s Empire Wind is getting a turbine-installation vessel this month to continue building. New York’s nuclear future is at a crossroads New York has its sights set on scaling up nuclear power — but faces dueling proposals on how to make it happen. It’s been nearly five years since the Indian Point nuclear plant fully shut down, taking with it a major supply of emissions-free power for New York City. Now, looking to spur a “nuclear renaissance,” the Trump administration is pushing for Indian Point’s restart. Energy Secretary Chris Wright recently joined the area’s Republican Congress member at a press event to call for the downstate plant’s reopening — an unlikely prospect given the surrounding communities’ opposition. After Wright’s visit, Democratic Gov. Kathy Hochul’s office affirmed she “will not support” Indian Point’s reopening. The plant is mired in intense controversy — something Hochul is probably reluctant to wade into during in an election year. But her administration is pressing on with plans to build a nuclear plant somewhere upstate, and so far, at least eight communities have said they’re interested in hosting it.

The government of Indonesia has launched a programme that aims to build 100GW of solar PV in the coming years, mostly distributed across smaller projects in rural areas. The programme will consist of 80GW of solar PV plants and 320GWh of battery energy storage systems (BESS) across 80,000 villages as 1MW solar PV capacity and 4MWh BESS, which will be managed by the Merah Putih Village Cooperative (KDMP). The village cooperative was launched last month by Prabowo Subianto, Indonesia’s president. Get Premium Subscription The capacity managed by the KDMP aims to provide reliable and affordable electricity to rural areas across the country and promote productive economic activities. In addition to the 80GW managed by the KDMP, the programme will also aim to build 20GW of centralised solar PV plants. The Indonesian energy sector think tank Institute for Essential Services Reform (IESR) praised the initiative, and its CEO, Fabby Tumiwa, said it was very appropriate for overcoming the challenges of energy transition and strengthening energy self-sufficiency. “If implemented effectively, this project will become the largest rural electrification initiative and distributed renewable energy generation program in Southeast Asia, addressing the challenges of providing quality, equitable, and affordable energy for all Indonesians,” said Tumiwa. This initiative comes two months after the Indonesian government ratified a plan to add 42.6GW of renewable energy capacity and 10.3GW of energy storage by 2034. The plan aims to support the country’s state-owned electricity company, for which solar PV will make up the bulk of the renewables, with 17.1GW. Despite that, the IESR highlighted three challenges that need to be addressed for the project to succeed, especially during the preparation and implementation stages. For starters, the selection of the locations for the PV plants to be built must take into account geographical conditions and electricity load requirements and ensure the technical and financial feasibility of the 80,000 planned projects. Secondly, the size of the projects – 1MW solar PV co-located with 4MWh BESS – will require at least 30 to 50 high-skilled workers for each project for up to a year from the preparation stage to the commissioning. According to IESR, the availability of workers capable of building solar PV and BESS projects is very limited and uneven across the country. The think tank calls on the government to conduct a workforce needs assessment and prepare certified installers through collaboration with vocational training centres, vocational schools, and universities. The training programme should also reach out to local communities where the projects will be built, in order to ensure local communities are involved in the construction of the projects. Finally, it suggests that the government make the programme a National Strategic Program (PSN) as the planning and implementation will require coordination across different ministries, local governments and stakeholders such as private businesses. IESR emphasised the need to prioritise rural communities’ involvement in the development of these solar-plus-storage projects, including planning, management, and utilisation.
Color Scheme Subscriber Actions Staff Options Connect With Us Support Local Journalism WASHINGTON – The war in Iran is choking off oil and gas supplies and spiking energy prices around the world. And for many environmentalists, that’s a powerful argument for countries to curb their use of fossil fuels and shift to wind, solar and other renewable sources. But as the chaos forces nations to rethink their energy policies, the results could be messy – and cleaner options may not always be the winner. Some countries in Europe and Asia may try to install more wind turbines, solar panels and batteries to buffer themselves against surges in the price of natural gas, as many did after Russia invaded Ukraine in 2022. If oil prices stay elevated, electric cars could become a more economical option for drivers from Brazil to the United States. “This newest upheaval shows yet again that fossil fuel dependence leaves economies, businesses, markets and people at the mercy of each new conflict,” said Simon Stiell, the United Nations climate chief. Investing in renewable energy, he said, is “the obvious pathway to energy security.” Yet other countries could respond to the supply crunch by burning more coal – a highly polluting fossil fuel, but cheap and readily available – or embracing U.S. natural gas. And if the Iran conflict causes interest rates to rise, that could make new renewable energy systems more expensive, analysts said. The Trump administration, for its part, has been urging nations to use more oil and gas and is pitching the United States as a stable supplier of fossil fuels in a dangerous geopolitical era. “It’s like an inkblot test,” said David Victor, a professor of public policy at the University of California, San Diego. “The war has reminded everybody of the powerful importance of energy security. And with that reminder, you have radically different responses.” The war also underscores a notable shift in the global energy landscape. For years, many world leaders declared tackling global warming a top priority and called for a shift to cleaner energy sources that didn’t heat the planet. But recently, rising geopolitical and trade risks have spurred countries to look for homegrown sources of any kind of energy. That could include solar or nuclear power but also coal or gas. The fighting in the Middle East has already exposed vulnerabilities in global energy markets. Roughly 20% of the world’s oil and much of its natural gas normally travels by ship through the Strait of Hormuz, a narrow waterway off the southern coast of Iran. Since the war began, Iran has been attacking tankers in the strait and traffic has slowed to a crawl, cutting off critical energy supplies. International oil prices rose by as much as one-third before dropping somewhat over the past few days. The shock waves have been profound. Qatar, which supplies one-fifth of the world’s liquefied natural gas, has halted gas production, leading to price spikes and factory shutdowns in faraway countries that rely on the fuel, including India, South Korea and Taiwan. In Vietnam, “sold out” signs are appearing at gasoline stations. In Pakistan, officials have urged four-day workweeks to save energy. Hungary and Croatia have imposed price controls on domestic fuels. In the short term, many countries are racing to secure energy supplies wherever they can. That often means scrambling for oil, gas and coal, which together still provide 80% of the world’s energy needs. In Thailand, which typically imports much of its natural gas from Qatar, officials have ordered domestic coal plants to run at full capacity and the national oil and gas company to maximize local production to make up the shortfall. In Taiwan, officials have broached the possibility of restarting a shuttered coal plant. In Europe, where natural gas prices have spiked more than 75% since the war began, nations are buying more U.S. liquefied natural gas, outbidding poorer countries like Pakistan and Bangladesh. “In the short term, countries will get energy wherever they can find it,” said Kevin Book, managing director of ClearView Energy Partners, a research firm. “But in the long run, there’s room for a rethink.” and gas imports Depending on the length and severity of the Iran conflict, some nations could seek to reduce their reliance on oil and gas imports from the Middle East in the coming years, experts said. That could be a boon for U.S. gas exporters who can offer an alternative to gas shipped through the Strait of Hormuz. Over the past decade, thanks to advances in fracking technology, the United States has become by far the world’s biggest supplier of liquefied natural gas, a form of gas that has been cooled for shipment. U.S. companies are expected to double export capacity by 2031. “The security argument for Qatari gas has really been undermined, and this is going to bolster the case for a lot of new LNG projects out there,” said Ira Joseph, a scholar at Columbia University’s Center on Global Energy Policy. Some countries in Southeast Asia and elsewhere could also turn to domestic sources of coal, the dirtiest of the fossil fuels but also widely available in many parts of the world. In recent years, nations such as India, Indonesia, Bangladesh and Pakistan have all been developing new coal plants, and global coal consumption has reached record highs. “If your goal is domestically produced energy and you’re South Africa or Indonesia or China, coal looks pretty good from energy security standpoint,” said Jason Bordoff, the founding director of the Center on Global Energy Policy. A far less polluting option would be for countries to invest in renewable energy sources such as wind and solar power, which do not require fuel and could help insulate them from volatile swings in gas and oil markets. After Russia invaded Ukraine in 2022 and cut off gas supplies, Europe stepped up its investment in solar power, with installations surging from roughly 40 gigawatts per year to nearly 65 gigawatts per year. (One gigawatt produces roughly enough electricity at peak output to power 300,000 homes.) Last year, nations spent more than $780 billion on renewable energy, according to the International Energy Agency, more than they invested in oil infrastructure. “My expectation, if post-Ukraine energy development is any indicator, is that it will accelerate further in countries that do not have access to fossil fuels,” said Ani Dasgupta, head of the World Resources Institute, an environmental group. A recent analysis from BloombergNEF, a research firm, suggested that the Iran conflict could give a boost to solar power and batteries, both of which have been rapidly falling in cost. Still, there are some obstacles that markets such as Europe and India will need to overcome, including grid congestion, land constraints and regulatory bottlenecks. Nuclear power is another option. In Japan, which is highly dependent on imported natural gas, officials have been gradually restarting nuclear plants that were closed in 2011 after a reactor meltdown at Fukushima. Those efforts could take on a new urgency, since each nuclear plant generally displaces gas power. Because clean energy and fossil fuels could both benefit, it is unclear what the shifting energy landscape would mean for greenhouse gas emissions. A case in point is China, which over the past 20 years has pushed hard to reduce its reliance on imported oil and gas – seemingly motivated far more by concern about energy security than climate change. China has fostered a cutting-edge electric vehicle industry, installed more wind and solar power than the rest of the world combined and is constructing dozens of nuclear power plants. But the country has also built hundreds of coal-burning power plants and – despite the heavy focus on renewables – has quickly become the world’s biggest emitter of planet-warming greenhouse gases, helping to push global temperatures to new highs. “While China is bearing some pain today, this crisis is in some ways a validation of their energy security strategy over the past 20 years,” Bordoff said. “In a world where energy is increasingly weaponized and energy security is more at risk, you would expect to see more countries try to reduce their dependence on imports.” The situation is somewhat different in the United States. Because natural gas markets are highly regional, America’s record gas production has kept the nation relatively protected from price shocks there. Natural gas is the biggest source of electricity in the United States, and the fact that it remains cheap means that other sources like wind, solar or nuclear power are unlikely to get any particular boost from the Iran conflict. Yet the price of oil, which is traded globally, has been rising, which in turn has made gasoline more expensive for drivers in the United States. That could make electric vehicles more competitive, according to a separate analysis by BloombergNEF. Today, U.S. gasoline prices are averaging around $3.50 per gallon. If prices were to climb to around $4.00 per gallon, the total cost of owning an electric car like the Tesla Model Y would be roughly similar to the total cost of owning a gasoline-burning Toyota RAV 4, because of the lower fuel costs, the analysis found. Still, there are plenty of complications, said Ethan Zindler, head of country and policy research at BloombergNEF. “Consumers would need to believe that prices are going to stay where they are,” he said. The United States, Canada and Europe have also put tariffs and other trade barriers on Chinese electric vehicles, which are some of the cheapest on the market today. Some experts wonder whether those dynamics could change if prices stay high for long enough. “The question is when does this crisis go on long enough that it starts to change people’s longer term thinking about energy policy and energy strategy,” Zindler said. “The higher that prices go, the bigger the shifts we could see.” This article originally appeared in The New York Times.

Nice, one of the Mediterranean’s most historic ports and seaside destinations, is presenting a new public boat show and industry forum that focusses exclusively on electric, hydrogen, solar, hybrid and other sustainable boat and boating technologies. Nice Boating Tomorrow has an impressive first year line-up of more than 80 exhibitors and 30 boats in-water, where will be able to take part in sea trials and experience first-hand the performance, comfort and smoothness of clean propulsion systems. The in-water exhibition will feature established shipyards alongside innovative start-ups and include everything from electric jetskis and dayboats to clean-energy cruising catamarans. Exhibitors are based in France, Finland, Croatia, Germany, Spain, the United Kingdom, Italy and Monaco. Electric motors, battery systems, solar panels, hybridization technologies, wind-assisted propulsion and more will be onshore along with boat retrofit solutions. Beyond electric vessels, visitors can explore sustainability options like deck coverings, eco-designed sails, bio-sourced nautical apparel and the services of naval architecture firms, eco-design studios and shared boating platforms. The four day public show (March 19 – 22) is centred around Quai Infernet , near the old town of Nice, and coordinates with an industry forum taking place the 19th and 29th at the OcéaNice Conference Centre in the centre of the city. The forum features conferences and expert panels addressing the key challenges and opportunities shaping sustainable boating in the centre of the city. Below are some highlighted electric boats and boating exhibitors at Quai Infernet and a schedule of the forum events that have electric propulsion as their topic. There is also an expandable guide to all electric boat exhibitors at the show that includes links to their websites. The impetus for Nice Boating Tomorrow came about partly because the OcéaNice centre hosted 2025’sThird United Nations Ocean Conference. The momentum from that show – and the importance of sustainable navigation to Nice and the Mediterranean in general, prompted the mayor of Nice, M. Christian Estrosi, to reach out to the organizers of the Grand Pavois La Rochelle boat show. The goal is to create “The first international boating event dedicated exclusively to sustainable boating, designed to become the leading global reference for tomorrow’s boating industry, fostering innovation visibility, exchange, collaboration and best practices in eco-navigation.” Over the past 7 years Plugboats has covered a number of new shows, in various countries that focus on electric boats and boating. The quantity and quality of exhibitors and the broad industry support for the first Nice Boating Tomorrow – along with the city itself and the expertise and experience of the Grand Pavois Organization – bode well for this and future editions.

Netherlands Boatee Outboard Italian startup Boatee made its industry and press debut at Metstrade last November and is set to enter the market with a lightweight new electric outboard. The motor has a strong and distinctive design that uses bold lines and a black and aqua colour combination. The most obvious functional element setting it apart is the flip top handle/tiller/monitor with information about the energy usage, battery state of charge and GPS up close to you at the end of the tiller handle. Steering and monitoring can also be done through a Bluetooth-connected smartphone app. The motor can be configured with power of 900W or 1300W (.9 kW or 1.3 kW) depending on the choice of battery: 24V, 36V or 38V. The batteries weigh 7.5 , 10.5 and 12.5 and have storage capacity of .720, 1.080 and 1.440 kWh. The motor itself weighs 6 kilos (13 lb). Boatee website Competr: contra-rotating propellers in a tractor electric OB We first saw the Competr at the 2025 Monaco Energy Boat Challenge, where it was powering both the University of Bologna’s winning entry in the Energy Class and the Red Wave RIB that won the SeaLab class. The motor was developed by students of the university under the leadership of U of B Professor Nicolò Cavina. The natural upshot of their work was to create a commercial entity, and Competr was showing their new product at METS. Weighing just 22 kg, the 26.9 kW (≈ 40 hp) motor is extremely efficient for two key reasons. One is the use of contra rotating propellers – a system where two propellers spin in opposite directions on the same shaft to contain the turbulence that a propeller generates. This can increase efficiency by as much as 16%. The second factor is the tractor motor configuration (Volvo Penta’s is the best known use of this technology) in which the propellers are ahead of the lower leg and pull the boat through the water. Competr will be in the ‘Pitch Your Project’ sessions of the International Forum at the OcéaNice centre. Competr website JOOOL JOOOL is a turnkey hybrid and electric propulsion system for sailing yachts developed and manufactured in France by the team behind Alternatives Energies, who have over 25 years of expertise in marine electrification. At its heart is the OneBox, a smart, compact energy management and conversion unit that integrates every onboard energy source and output: battery, solar, wind, hydrogeneration, gensets and shore power. It oversees and controls not only the propulsion system in real time, but also all energy use, with easy to read monitor interfaces. JOOOL websiteRead more about JOOOL in Plugboats Dhamma Blue DB P01 I had a chance to go out on the hydrogen electric hybrid DB P01 at the Monaco Energy Boat Challenge last year. It is an extremely well designed boat that does everything well. The 120 kW (190 hp) motor easily has enough for waterskiing or wakeboarding, it can cruise for 65 Nm (120 km / 75 mi)) miles at 12 knots (22 kph/ 14 mph) and the control system automatically optimizes the combination of hydrogen fuel cell or battery power required for any speed or condition. With a length of 7.9m / 26 ft and a beam of 4.55m / 8.3 ft, there is plenty of space for up to 7 passengers who have the option of relaxing on one of two sunbeds that lead to a small swimming platform. Dhamma Blue Co-founder Philippe Esposito will be part of a panel at the International forum investigating ‘Hydrogen and leisure boating: what are the possibilities’. Dhamma BlueRead more about the DB P01 in Plugboats Elvene Elvene is a Finnish boatbuilder founded by Emil Finne to bring a fresh, environmentally friendly dimension to boating. The hulls of traditional Finnish boats were designed for easy sailing – and had proven their capbilities – long before motors could overcome any inefficiencies, so he looked to them to create modern boats that could run for the maximum time on electric and solar power. Two Elvene boat models will be at Nice Boating Tomorrow, both built on the same 6.5m / 22 ft. hull design. The Amy is an open deck boat with solar panelled roof, the Amber has a Cuddy-Cabin for overnight stays and slightly larger roof. They come with either a side or centre console layout and can be powered with a single motor as small as 3kW or twin motors with combined 50kW of power. Battery storage can be either 22kWh or 44kWh, and in every case the combination of battery and solar power offers limitless range at low speed, as proven in the low sunlight of Finland and demonstrated in this video below by Justin Dallinger of AquaLectric. Elvene website Lasai 32KS solar-electric overnighter Spanish solar electric boat manufacturer Lasai had the range of their 22GL solar-electric model certified by Bureau Veritas this year, racking up a trip of +100 nautical miles over 18 hours on a single charge. Their fourth model – the Lasai 32KS – is a larger boat designed for overnighting instead of day use alone. Using the learning from their smaller models, the designers and engineers used a catamaran design, which creates less drag and water resistance than a monohull and also allows for a wide spacious helm and deck area along with a fully equipped interior cabin with en-suite head. The overall look both in and out is clean and sleek. Elegant lines and a refined silhouette stand up to closer inspection with attention having been paid to the finishing details.

Vanair is expanding its EPEQ Electrified Power Equipment ecosystem into the Class 8 trucking segment with a suite of battery-electric auxiliary power products designed to reduce engine idling and support growing electrical demands in over-the-road trucks. The system was introduced during a press conference at the Technology & Maintenance Council’s 2026 meetings. Originally launched in 2020 for vocational work trucks, the EPEQ platform provides battery-powered air compressors, welders, hydraulic systems and AC power for service vehicles and utility fleets. The latest expansion includes new 12-volt batteries and inverters, upgraded 48-volt lithium iron phosphate batteries designed for frame-rail mounting, and a solar charging system. Vanair says the system is designed to power sleeper cab hotel loads, support liftgate and refrigeration batteries, and reduce engine idling. “Drivers need reliable heating, cooling and electrical power without running the main engine,” said Chip Jones, national manager of the Electrified Products Group for Vanair. “Fleets need to protect expensive assets from the wear that idling causes. What we bring to this market is not a single-purpose APU. It’s a complete, integrated power ecosystem that scales to the application.” At the core of the system are ELiMENT lithium iron phosphate batteries. The 48-volt units are available in 5-kW modules that can be connected in parallel to deliver up to 30 kW of power. The batteries feature IP67-rated enclosures designed to withstand exposure to road spray, mud and debris when mounted on truck frame rails. For sleeper cab applications, EPEQ inverters convert battery power to run HVAC systems, refrigerators, microwaves and other hotel loads during rest periods without idling the truck engine. The batteries recharge through the truck’s alternator while driving and can also be charged through shore power. Unlike diesel auxiliary power units, the system has no combustion engine, no exhaust and no fluid maintenance requirements, Vanair said. The company also introduced a 12-volt product line that includes lithium iron phosphate batteries in 100-Ah and 200-Ah configurations and pure sine wave inverters ranging from 1,000 to 3,000 watts. These systems are intended for lighter auxiliary loads such as powering onboard electronics, charging cordless tools or operating 120-volt equipment in day cabs or maintenance vehicles. Vanair’s Solar Assist system is designed to help maintain battery charge levels while trucks are parked. Flexible adhesive-mounted panels can be installed on cab fairings or trailer roofs and are designed to operate in partial shade and low-angle light conditions. The solar system is intended to address battery drain caused by telematics, electronic logging devices, GPS units and other onboard electronics that continue drawing power while trucks are parked. Jones said the solar system can extend battery life by up to 200%. In testing, Jones said trucks fitted with the system have seen idle time decrease to 1%. The EPEQ system also includes a battery-driven hydraulic power option known as EPTO, capable of delivering up to nine gallons per minute of hydraulic flow to operate pumps, liftgates, compressors and other equipment without idling the truck engine. Jones said the integrated system is intended to simplify auxiliary power management for fleets. “Most electric APU solutions handle hotel loads,” he said. “The EPEQ ecosystem does that, but it also provides air compressor power, hydraulic power, solar charging and idle management in a single architecture.” Vanair said the system is designed to help fleets extend vehicle life, reduce maintenance costs and lower emissions by minimizing engine idling. The solar panels can also be mounted to trailer roofs to power refrigeration units and liftgates. Jones said the panels are lightweight, rugged and offer 20% more energy output compared to existing designs in real-world applications. If an individual module goes out, the rest of the panel will continue to function, he added. James Menzies is editorial director of Today’s Trucking and trucknews.com.

Tongwei Co Ltd stock (ISIN: CNE1000019K1), a leading Chinese polysilicon and solar cell producer, grapples with falling prices and overcapacity in the photovoltaic supply chain, prompting investor caution despite strong fundamentals. Tongwei Co Ltd stock (ISIN: CNE1000019K1) has come under pressure as the solar industry contends with persistent oversupply and declining polysilicon prices. The company, a dominant player in China’s photovoltaic materials sector, reported robust production volumes in recent quarters but faces margin compression from market dynamics. European investors tracking renewable energy supply chains are watching closely for signs of stabilization. As of: 15.03.2026 By Dr. Elena Voss, Senior Solar Energy Analyst – ‘Tracking China’s pivotal role in global PV supply for European portfolios.’ Tongwei Co Ltd, listed on the Shenzhen Stock Exchange under ISIN CNE1000019K1 as ordinary A-shares, operates primarily as a vertically integrated producer of polysilicon, wafers, cells, and modules. The stock has experienced volatility tied to commodity pricing in the solar value chain. As of mid-March 2026, shares reflect broader sector weakness, with polysilicon spot prices hovering at multi-year lows due to expanded capacity across Chinese producers. Investors note Tongwei’s strategic positioning: it controls over 20% of global polysilicon output, leveraging cost advantages from its proprietary FBR technology. However, end-market demand softness in Europe and the US, coupled with aggressive expansion by peers, has led to inventory buildups. For DACH region investors, this scenario echoes past cycles in commodity-driven sectors like chemicals, where pricing power dictates returns. Official source Tongwei’s latest quarterly results highlighted record polysilicon production, exceeding 200,000 tons in Q4 2025, underscoring its scale advantages. The company maintained high utilization rates at its facilities in Sichuan and Inner Mongolia, benefiting from low-cost captive power generation. Cell and module shipments also grew, supporting downstream integration. Yet, guidance points to challenges: management flagged potential revenue pressure from N-type cell pricing, which fell 15-20% sequentially. Cash generation remains solid, with net cash positions bolstering capex for next-gen TOPCon lines. European analysts view this as a classic operating leverage play in semiconductors-adjacent manufacturing, where fixed costs amplify volume swings. The photovoltaic industry is grappling with overcapacity at every stage, from ingots to modules. Tongwei, as China’s second-largest polysilicon maker after GCL-Poly, competes in a market where total capacity now surpasses 2 million tons annually against demand of about 1.5 million. This mismatch has crushed prices, with electronic-grade polysilicon trading below production costs for some players. Tongwei differentiates through vertical integration, capturing value across the chain and mitigating pure-play polysilicon exposure. Its mono wafer output supports high-efficiency products, aligning with global trends toward 500W+ modules. For German investors familiar with Meyer Burger’s struggles, Tongwei represents the low-cost anchor in an otherwise inflationary supply chain. Gross margins for Tongwei’s polysilicon segment have compressed to the mid-teens from over 40% peaks in 2022, reflecting raw material stability but pricing erosion. Downstream cells offer better resilience, with N-type efficiencies above 25% driving premium pricing. Electricity costs, a key input at 30-40% of COGS, are hedged via self-owned hydro and coal plants, providing a moat versus import-reliant competitors. Operating leverage is pronounced: a 10% volume uptick could expand EBITDA margins by 5-7 points, assuming stable pricing. Balance sheet strength, with debt-to-equity under 0.3, enables sustained capex of RMB 50-60 billion annually. Swiss investors, attuned to precision manufacturing margins, appreciate this discipline amid capex cycles. While Tongwei lacks a direct Xetra listing, its ADRs and H-shares offer indirect exposure via Hong Kong. For DACH portfolios heavy in renewables like SMA Solar or Encavis, Tongwei provides supply-side hedging against European equipment makers’ cost inflation. EU anti-dumping duties on Chinese modules heighten relevance, as Tongwei’s overseas module plants in Indonesia and Vietnam navigate trade barriers. Austrian and Swiss funds tracking ESG mandates find Tongwei’s low-carbon production appealing, with lifecycle emissions 20% below industry averages. However, geopolitical risks, including US IRA exclusions for Chinese content, cap upside for Western capital. This creates a trade-off: compelling valuations versus regulatory hurdles. Related reading Tongwei trails only LONGi in overall PV market share but leads in polysilicon purity for high-end applications. Rivals like Daqo and Yongxiang face higher costs, positioning Tongwei for market share gains in a consolidation phase. Globally, First Solar’s thin-film tech poses niche threats, but crystalline silicon dominance persists. Sector tailwinds include India’s 50GW annual tenders and Southeast Asia’s manufacturing shift. Headwinds from US tariffs and EU CBAM could redirect exports, pressuring domestic pricing further. Analyst consensus leans neutral, with targets implying 15-20% upside from current levels if prices bottom. Potential catalysts include capacity utilization cuts by smaller producers, stabilizing prices by Q2 2026, and Tongwei’s bifacial module launches boosting ASPs. Dividend yields around 2%, backed by FCF, appeal to income-focused European investors. Risks encompass prolonged oversupply, RMB depreciation eroding dollar revenues, and policy shifts under new US administration. Outlook favors recovery as global solar additions hit 500GW in 2026, per BloombergNEF estimates. Tongwei’s scale and tech edge position it for outperformance, though volatility persists. DACH investors should weigh China exposure against diversified solar ETFs for balanced risk. Disclaimer: Not investment advice. Stocks are volatile financial instruments.

We may collect a share of sales from items linked to on this page. Learn more. Power outages are becoming more common across North America. Severe storms, aging infrastructure, and increasing demand on the electrical grid mean that interruptions in electricity are no longer rare events. In many areas, outages that once lasted minutes now stretch into hours or even days. When that happens, everyday essentials like refrigeration, internet access, and home heating systems can quickly become unavailable. For decades, gasoline generators have been the standard solution for backup power. They can certainly get the job done, but they come with clear tradeoffs. Generators are loud, require fuel storage, produce emissions, and must be operated outdoors. Portable battery power stations have emerged as a cleaner and quieter alternative. These systems store electricity in rechargeable batteries and deliver it on demand to power appliances and electronics. Many models can also recharge from solar panels, making them particularly appealing for people looking to reduce reliance on fossil fuels. The BLUETTI Elite 300 sits toward the larger end of the portable power station category. With just over 3 kWh of battery capacity and a 2,400-watt output, it is designed to provide meaningful backup power while still remaining portable enough for RV travel, outdoor use, and emergency preparedness. In this review, we take a closer look at the Elite 300 to see how it performs in real-world scenarios, including its design, power capabilities, charging performance, and whether it makes sense as a practical backup power solution. BLUETTI markets the Elite 300 as the smallest 3 kWh portable power station, combining a large battery capacity with a relatively compact footprint. Key specifications In practical terms, this capacity places the Elite 300 in a category where it can power more than small electronics. It has enough stored energy to keep essential household devices running during an outage, including refrigerators, routers, lighting, and other appliances. The 2,400-watt inverter also allows it to handle higher draw devices such as microwaves, coffee makers, and power tools. BLUETTI positions the Elite 300 as a flexible power solution for several types of users. Homeowners looking for backup power during outages will appreciate the UPS capability and large battery capacity. RV owners and van travelers benefit from the dedicated RV outlet, while campers and outdoor workers gain a portable power source that can recharge from solar panels.

With a 2,400 W inverter, fast recharging, and solar compatibility, it delivers reliable electricity for appliances, electronics, and emergency preparedness. The Elite 300 immediately feels like a substantial piece of equipment. Despite its large battery capacity, BLUETTI has kept the overall footprint relatively compact for a power station in this class. The unit measures 14.4 × 12 × 11.7 inches, which is fairly compact for a 3 kWh system. At 58 pounds, it is not lightweight, but still manageable for a single person to lift when needed. This makes it practical to transport in a vehicle, move around a campsite, or store for emergency backup. Build quality is solid. The housing uses durable molded plastic with reinforced edges that give the unit a rugged feel. It does not flex when lifted and appears well suited for repeated transport and outdoor use. Large integrated carry handles on the top of the unit make lifting easier and feel sturdy relative to the weight of the battery. On the front panel, a central display screen shows input power, output load, and remaining battery capacity. The screen is easy to read and presents the information clearly. Cooling is handled through side ventilation ports, which allow the internal system to regulate temperature during heavy loads or charging. The port layout is well organized on the front of the unit. AC outlets, USB ports, and DC outputs are grouped logically and spaced far enough apart to accommodate larger adapters. Another notable feature is the LiFePO₄ battery chemistry, which BLUETTI rates for more than 6,000 charge cycles. This type of battery is known for long service life and stability, which can translate to many years of regular use. With just over 3 kWh of stored energy, the Elite 300 can power many household devices rather than just small electronics. The unit delivers 2,400 watts of continuous AC output, which covers most everyday appliances including refrigerators, televisions, routers, lighting, laptops, and kitchen appliances. In practical use, this allows several devices to run at the same time without approaching the inverter’s limits. The system can also handle surge loads up to 4,800 watts, which helps support appliances that briefly draw extra power when they start. In real-world use, a battery of this size can keep a refrigerator running for extended periods, operate kitchen appliances like a microwave or coffee maker, and recharge phones and laptops many times over. BLUETTI also includes Power Lifting Mode, which allows the unit to run certain high-resistance appliances that would normally exceed the inverter rating. Devices like kettles, toasters, or small heaters may operate in this mode because the system adjusts how power is delivered to manage the load. A portable power station is only as useful as the devices it can power, and the Elite 300 includes a range of outputs designed to support everything from small electronics to larger appliances. The Elite 300 includes five AC outlets, all drawing from the 2,400-watt inverter. This allows several devices to run simultaneously without requiring additional splitters. The outlets are spaced far enough apart to accommodate large power adapters. For charging smaller electronics, the Elite 300 includes several USB and DC options: These higher-power USB-C ports can charge laptops, tablets, cameras, and other modern electronics. A 120-watt car-style DC outlet is also included for accessories such as portable refrigerators or inflators. The Elite 300 is also designed with RV users in mind. It includes a NEMA TT-30 RV outlet as well as a 12 V / 30 A DC port for higher-demand equipment such as RV refrigerators, lighting systems, or onboard devices. These connections make the unit especially appealing for RV owners, van life setups, and mobile workspaces, allowing users to power essential systems without relying on campground hookups or generators. The Elite 300 supports several charging methods, allowing it to recharge from the grid, solar panels, or a vehicle. Charging from a wall outlet is the fastest option. The unit supports AC charging up to about 2,300 watts, allowing it to recharge quickly for a battery of this size. Under maximum AC charging, the battery can reach roughly 80 percent in about 78 minutes and fully recharge in around 1.6 hours. The Elite 300 also supports up to 1,200 watts of solar input, making it suitable for off-grid setups. With a solar array close to the maximum input, the unit can recharge in roughly four hours of strong sunlight. The system can also accept AC and solar input simultaneously, allowing a combined input of up to 2,400 watts for even faster charging. The unit can also recharge from a vehicle’s 12-volt system, though this is best viewed as a backup charging option. It is considerably slower than AC or solar charging but can be useful during travel or emergencies. The Elite 300 also supports pass-through charging, meaning it can power connected devices while the battery is being recharged. One of the more useful features of the Elite 300 for home use is its built-in UPS function. When connected between a wall outlet and your devices, the unit can automatically switch to battery power if the grid goes down. The system has a 10 millisecond switchover time, allowing it to instantly switch to battery power during an outage. This makes it useful for devices that benefit from continuous power, including: For many households, this feature allows the Elite 300 to act as a small backup power hub for essential devices without the cost or complexity of installing a full home battery system. The Elite 300 can be managed through the BLUETTI mobile app, which adds remote monitoring and control. Through the app, users can monitor: This is helpful when the unit is stored in a garage, RV compartment, or another location where the display is not easily visible. The app also provides energy usage monitoring, which helps users understand how much power connected devices are consuming. Users can configure scheduled power control, allowing certain outputs to turn on or off automatically. Another feature is remote wake-up, which allows the power station to be activated without pressing the buttons on the unit. Connectivity is handled through Bluetooth for local control and Wi-Fi for remote monitoring, and setup typically takes only a few minutes. With its combination of capacity, output, and port options, the Elite 300 supports several practical scenarios. During outages, the Elite 300 can keep essential appliances running, including refrigerators, lighting, routers, and small electronics. For shorter outages, this can maintain basic household functionality without running a generator. The TT-30 outlet allows the unit to power RV electrical systems directly. This makes it useful for road trips or overnight stops where campground hookups are unavailable. Portable power stations have become popular for camping setups and remote work environments. The Elite 300 can power lights, laptops, cooking appliances, cameras, or small tools. For households focused on emergency preparedness, a power station like the Elite 300 can be part of a backup plan during storms or extended outages. When paired with solar panels, it can be recharged even when the grid is unavailable. With a 58-pound weight, the Elite 300 is not designed for frequent long-distance carrying. However, for a power station with this capacity, the weight is typical. The unit is best thought of as transportable rather than highly portable. It can easily be lifted into a vehicle, moved around a garage, or repositioned at a campsite. Compared with many other 3 kWh power stations, the Elite 300 is relatively compact, which makes it easier to store and transport. For most users, this balance between capacity and portability will make sense Portable battery power stations provide a cleaner alternative to traditional generators. The Elite 300 supports solar charging, allowing users to recharge the battery using renewable energy rather than relying solely on grid electricity. This reduces reliance on gasoline generators, which produce emissions and require fuel storage. Battery systems like the Elite 300 produce no direct emissions during operation, making them safe to use indoors. They are also much quieter than gas generators, producing only minimal fan noise during heavy use or charging. When paired with solar panels, the Elite 300 can function as part of a small-scale renewable energy system. BLUETTI offers power stations ranging from small portable models to modular home backup systems. The Elite 300 sits in the middle of that lineup. The Elite 200 V2 offers about 2,073 Wh of capacity and slightly higher inverter output at 2,600 watts. It is easier to carry and better suited for camping or shorter backup needs.

The United States imported approximately 14 billion U.S. dollars worth of solar PV modules between January and October 2024. Almost 40 percent of these solar panels imported into the U.S. during this period came from Vietnam.
In 2012, the Obama administration implemented duties on solar equipment imported from China to counteract the competitive edge held by foreign companies. These levies were then expanded in 2015, leading to the gradual phase-out of Chinese solar imports. Since then, the U.S. solar market has heavily relied on equipment assembled in SE Asia. However, in April 2022, the U.S. Commerce Department launched an import-tariff-circumvention investigation, under the suspicion PV modules imported from these countries contained components made in China. In August 2023, the Commerce Department published its final conclusion, stating that a number of the investigated companies were violating U.S. laws.
The price of solar PV modules in the United States has seen an overall decline since 2015, despite some fluctuations. During the same period, the number of solar energy-related jobs in the North American country has been on a mostly upward trend, reaching a record high of nearly 280,000 jobs in 2023. Altogether, the U.S. solar energy industry continues to prosper in spite of the import tariffs placed on this renewable energy source.

Media Release Australian rooftops are about to get more powerful. AIKO has announced the Australian launch of its third-generation ABC 60-cell solar module, bringing one of the world’s highest-efficiency solar panels to local homes and businesses. The module has received Clean Energy Council approval and will begin arriving in Australia from late April 2026. With power ratings up to 545W and module efficiency exceeding 25%, the new panel is designed to help households and businesses generate more electricity from the same roof space. From residential rooftops to commercial systems and off-grid installations, AIKO’s latest technology aims to deliver greater output, improved durability, and simpler installation. The Gen 3 ABC 60-cell module delivers up to 545W of output within a compact footprint measuring 1954 × 1134 × 30 mm. This allows installers to deliver more power without increasing the physical size of the panel. Compared with similarly sized TOPCon panels, the module can produce up to 30W more power per panel. Over its lifetime, this translates to roughly 15% higher energy yield per square metre. This performance advantage comes from AIKO’s patented Infinite ABC technology. The design focuses on maximising the active area of each panel while reducing electrical losses. Several innovations make this possible. The module uses a Zero-Gap cell layout that eliminates wasted space between cells. It also uses Invisi-Ribbon interconnection, along with a grid-free front surface that maximises sunlight capture. Another key improvement is the use of copper interconnection instead of traditional silver. This increases cell bending strength by around 20%, helping reduce the risk of microcracks that can degrade performance over time. The module is also designed for Australia’s harsh climate. With a temperature coefficient of −0.26% per degree Celsius, the panel maintains stronger performance during hot weather conditions, which are common across much of the country. Australian households are electrifying at a rapid pace. Electric vehicles, heat pump hot water systems, induction cooking, and home batteries are all driving demand for larger solar systems. However, roof space often limits how much solar can be installed. The Gen 3 ABC 60-cell panel addresses this challenge by delivering higher power in a compact format. This allows homeowners to install more system capacity on the same roof. For many households, this means faster battery charging and more solar energy available to run an increasingly electrified home. As feed-in tariffs continue to decline across Australia, maximising self-consumption has become more valuable. Generating more solar energy on-site helps households reduce grid reliance and lower electricity bills. Higher output panels also reduce the total number of modules required for a system. Fewer panels can mean fewer roof penetrations and more flexibility when designing systems around chimneys, skylights, or shaded areas. The panel’s all-black design and grid-free surface also deliver a sleek rooftop appearance. This is particularly appealing for homeowners who want solar to blend seamlessly into their home’s design. Commercial buildings often have a large electricity demand but a limited rooftop area. In these situations, increasing the output of each panel can significantly improve project economics. Higher power panels allow developers to increase system capacity without expanding the installation footprint. For example, on a typical 660 square metre commercial rooftop using 196 modules, system capacity could increase from around 100 kW using 510W TOPCon panels to approximately 107 kW using 545W Infinite modules. Over a 30-year project life, this capacity increase can raise the projected electricity value from roughly $360,000 to around $400,000. That represents an uplift of around 11% while system cost per watt remains largely unchanged. There are also practical installation benefits. Because fewer panels are required to reach target capacity, installers can reduce racking hardware, DC wiring, and installation time. For businesses pursuing decarbonisation goals, higher-efficiency panels provide a straightforward way to maximise renewable generation from existing roof space. Solar systems in Australia often operate in demanding conditions. From remote off-grid sites to bushfire-prone regions, durability is essential. The Infinite 60-cell mono-glass variant uses 3.2 mm front glass. This is approximately 60% thicker than the front glass used in some dual-glass TOPCon products. The modules are certified for 35 mm hail impact under international testing standards. Many conventional panels are only certified for 25 mm hail impact. For sites located in bushfire-prone areas, dual-glass variants carry IEC Fire Class A certification, which is the highest fire safety classification available. Inside the panel, AIKO replaces conventional silver soldering with proprietary copper electroplated interconnection. This creates stronger joints with tensile strength exceeding 5N. In impact testing, ABC cells subjected to identical 2 kg mechanical stress experienced only 16% current loss. Comparable TOPCon cells recorded around 45% current loss under the same conditions. For remote or off-grid systems, where maintenance visits can be expensive, improved durability can help reduce downtime and service costs. The Gen 3 ABC 60-cell range is also designed to simplify installation. Higher output means fewer panels are needed to achieve the same system capacity. This reduces racking, cabling, and labour requirements. Using one high-performance panel format across residential, commercial, and off-grid applications can also simplify product selection and inventory management for installers. “Australian installers are under real pressure right now: more competition, tighter margins, and customers who want more from their solar investment,” said Thomas Bywater, Head of Australia, New Zealand and New Caledonia at AIKO Energy. “AIKO’s Gen 3 ABC 60-Cell gives them one solution for every job on the list: homes, C&I, and off-grid. Same format, same install process, same warranty conversation. That simplicity is what lets a good installation business grow into a great one.” Australian installers will not have long to wait. Initial supply will begin from late April 2026, with 535W and 540W models available for general supply. The 545W variant will be available in limited production quantities. Additional versions are scheduled to arrive later in 2026. These include dual-glass models and full-black options designed for premium residential installations. As Australia’s energy transition accelerates, higher-efficiency solar panels will play a critical role in helping homes and businesses generate more clean energy from limited rooftop space. The launch of AIKO’s Gen 3 ABC 60-cell module represents another step forward in that journey. Ready to add AIKO solar panels to your home or business?

To address this challenge, an optimization approach for oil well operation scheduling is proposed, which couples photovoltaic power fluctuations with the characteristics of intermittent pumping technology. Firstly, a multiobjective optimization model was developed to minimize grid electricity consumption per unit of liquid production and maximize the share of green electricity. The on-off schedule was mapped into a constrained binary sequence using a run-length encoding to reducing the solution space. Non-dominated Sorting Genetic Algorithm II (NSGA-II) was improved to increase both accuracy and convergence speed by introducing: (1) dual-mode initialization strategy guided by historical operating schedules and photovoltaic fluctuations. (2) a key-gene-preserving crossover operator to retain high-matching time segments; and (3) a peak-valley-guided mutation strategy to enable dynamic pruning of the solution space and goal-directed optimization. Case studies showed that the proposed method doubled green electricity consumption under stable production conditions, reduced grid electricity consumption per unit liquid by 41.67%, improved computational efficiency by two to three orders of magnitude, and enhanced the solution accuracy by 26.69%, indicating strong practical applicability. As a core carrier of traditional energy production and consumption, China’s oil and gas field operations account for approximately 20.65% of the total electricity consumption in the mining industry1. The wide geographical distribution of field facilities, each single-well site occupying an average area of no less than 1,300 (:{m}^{2})2, combined with well-developed grid infrastructure, offers a unique spatial-energy coupling advantage for the distributed deployment of renewable energy systems such as wind, solar, and geothermal systems. Promoting the construction of renewable energy projects can enable the substitution of conventional electricity with green electricity for production purposes, thereby enhancing energy conservation and emission reduction performance and supporting the oilfield sector’s efforts to achieve the national “dual carbon” targets3,4,5. Chinese oilfield enterprises are accelerating green electricity deployment6. The integration of green electricity into the power grid intensifies the grid’s regulatory burden, has attracted scholarly attention from the supply side, including studies on grid energy efficiency7, distribution system optimization8, grid stability9, and the formulation of tiered electricity pricing10. Nevertheless, in the absence of a fundamental shift in end-use electricity consumption patterns, it remains challenging for green electricity to serve as an effective substitute for conventional energy. For oil enterprises, the deployment of self-owned green power projects is constrained by their potential impacts on the grid system. Currently,, the overall economic viability of such projects remains limited due to low onsite consumption, low feed-in tariff for green electricity and high wind and solar curtailment rates in certain regions11,12. Therefore, improving the self-consumption ratio of green electricity and optimizing consumption models, such as through energy storage systems or microgrids, has become critical to enhancing the economic performance of green power projects in the oilfield industry. Approximately one-third of electricity consumption in oilfield production is attributed to artificial lift systems13. Compared with continuously operating wells, low-producing and low-efficiency wells that operate intermittently exhibit a more interruptible load characteristics. By dynamically adjusting their operating schedules, the spatiotemporal distribution of load can be shifted to accommodate the intermittent output of green electricity, thereby improving source-load coordination efficiency in scenarios with highly fluctuating power supplies. Existing studies on intermittent pumping schedule optimization mainly follow two technical routes: one based on dynamic liquid level and the other based on well on-off period as the decision variable for intermittent operation. A detailed literature comparison is shown in Table 1. These studies primarily focused on conventional oilfield production scenarios with stable grid energy supply, where operating schedule optimization was typically determined along two dimensions of on-off duration or liquid level, and the system ran in periodic alternation according to the optimized schedule. In such scenarios, the real-time requirement for optimization algorithms was relatively low. However, directly applying conventional methods to renewable energy scenarios with fluctuating power supply often leads to mismatches between load demand and source-side supply, resulting in insufficient green electricity utilization, higher curtailment rates, and weaker source-load matching, which ultimately undermine project economics. This limitation arises primarily because conventional control strategies fail to adequately capture the dynamic and uncertain nature of fluctuating energy, thereby hindering effective temporal matching between supply and load. To address this challenge, it is essential to develop load optimization approaches tailored to the fluctuating characteristics of renewable energy supply. Such approaches can enhance green electricity utilization and improve system operational efficiency, thereby strengthening source-load matching and maximizing the economic and environmental benefits of renewable energy. Several scholars have investigated the optimization of intermittent pumping schedules under fluctuating energy supplies. Sun et al. (2023)19 investigated the optimization of intermittent pumping schedules for individual wells and developed a model with a 30-minute temporal resolution. The study focused on day-level on-off schedule optimization under two typical scenarios: tiered electricity pricing and photovoltaic (PV) power generation. The problem was solved via NSGA-II, with 48 decision variables, a population size of 2000, and 500 generations. Wang et al. (2025)20 addressed the optimization of intermittent pumping schedules for well clusters powered by wind-solar-storage microgrids. They proposed a scheduling optimization method based on a hybrid intelligent algorithm and established a model with a 1-hour temporal resolution and a 24-hour planning horizon. To enhance algorithm convergence, improvements were made to the inertia weight and learning factors of the particle swarm optimization (PSO) algorithm, as well as to the adaptive crossover probability and dynamic mutation rate of the genetic algorithm (GA). These studies formulated the intermittent pumping schedule optimization problem as a 0–1 integer programming model, where the solution space exhibits double-exponential growth with finer time granularity and an increasing number of wells. Although improvements in algorithmic parameters (e.g., inertia weights, learning factors) have been employed to enhance search efficiency, two fundamental challenges remain. First, the proliferation of infeasible solutions: many candidate solutions generated during the search process violate engineering constraints such as dry pumping or minimum/maximum allowable continuous operating or stoppage duration, degrading solution quality and undermines engineering reliability. Second, the curse of dimensionality: the high-dimensional search space deteriorates convergence characteristics, often leading to premature convergence and a greater risk of entrapment in local optima. As a result, the likelihood of obtaining feasible solutions within limited adjustment cycles decreases, making it difficult for the optimized pumping schedules to dynamically track renewable energy fluctuations, thereby weakening source-load matching and ultimately constraining the overall system performance. In this study, we investigate the optimization of intermittent pumping schedules for oil wells under PV grid-connection scenarios. A multi-objective optimization model is developed to minimize grid electricity consumption per unit liquid production while maximizing the share of green electricity. To address the challenges of solution space complexity, a run-length encoding scheme is employed to define optimization parameters, and its effect on feasible solution distribution is analyzed. Furthermore, prior knowledge, including PV fluctuation patterns and original pumping schedules, is integrated into the algorithm design, with targeted improvements made to initialization, crossover, and mutation operators. Comparative experiments confirm that the proposed method achieves higher optimization accuracy and efficiency, thereby enhancing the practical applicability of intermittent pumping schedule optimization under renewable energy scenarios. This study investigates the optimization of on-off scheduling for intermittent pumping well systems in scenarios involving grid-connected photovoltaic systems without energy storage, under a renewable-energy-priority supply scheme, as shown in Fig. 1. The system operates with a parallel power supply from both a PV array and the conventional electrical grid. It is designed without energy storage, prioritizing the utilization of green energy from the PV array. When PV power is insufficient, the system automatically switches to grid electricity to ensure continuous operation. Intermittent pumping wells, as critical loads, are required to fulfill the inflexible demand of a minimum daily oil production, while simultaneously possessing the potential for load shifting21. By integrating real-time PV output with load demand, the controller optimizes the on-off scheduling of intermittent pumping wells to achieve source-load matching. Structure of intermittent pumping wells under grid-connected pv systems. The oil well system is a multi-domain, strongly coupled dynamic system that integrates surface electromechanical equipment, multiphase flow in the wellbore, and reservoir seepage. Its dynamic processes span multiple time scales, ranging from seconds (electromechanical responses) to days (reservoir recovery). Single time-scale modeling presents inherent limitations: a fine-grained second-level scale can capture equipment dynamics but leads to excessive computational costs, whereas a coarse-grained hourly scale sacrifices responsiveness to PV fluctuations. To overcome these limitations, this study proposes a multi-time-scale collaborative optimization method. Specifically, system performance evaluation and planning are conducted on a daily scale, while a minute-level scheduling interval is employed to achieve high-precision dynamic matching between PV output and oil well load, thereby effectively balancing computational efficiency and control accuracy. Taking intermittent pumping wells with original pumping cycles not exceeding 24 h as the research object, the relationship between the daily planning cycle and the basic scheduling unit is established as shown in Eq. (1). where, (:text{T}) is the planning horizon, min, in this model, (:T=1440:min), i.e., one day. (:{Delta:}text{t}) denotes the basic scheduling unit, min; in this model, (:{Delta:}text{t}=10:text{m}text{i}text{n}). (:text{t}) represents the index of discrete time intervals within the planning horizon; there are (:{n}_{t}) intervals in total. Drawing on the run-length encoding (RLE) technique from data compression algorithms22, the optimization parameters consist of three parts: the initial state, the sequence of 0-run lengths, and the sequence of 1-run lengths (Fig. 2). This method is referred to as the optimization parameter definition and is based on 0–1 run-length encoding (0–1 RLE). Optimization parameter structure based on 0–1 RLE. The state of intermittent pumping wells typically alternates between start and stop phases; therefore, given the initial state, the subsequent on-off states of the well can be determined, as defined by Eq. (2). where, (:{text{S}}_{0}) denotes the initial state. 1 represents the on and 0 represents the off. If the initial state is 1 (i.e., on), then the subsequent on-off sequence of the well must follow the following pattern: on–off–on… (i.e., 101…). The sequence of 0-run lengths is defined to represent the durations of stoppage periods, as shown in Eq. (3). where, (:{tc}^{i}) denotes the length of the i-th 0-run (stoppage duration). (:{tc}^{i}times:varDelta:text{t}) represents the continuous stoppage duration. Its minimum value cannot be less than the lower bound of a single well stoppage duration (:{text{T}}_{1,text{c}}) to avoid frequent on-off cycles that could reduce equipment lifespan. Its maximum value is the difference between the planning horizon (:T) and the lower bound of a single well operating duration (:{text{T}}_{1,text{o}}), ensuring that both start and stoppages occur at least once within the planning horizon. (:i) is the index of the run-length (RL) sequence, with a minimum value of 1, indicating at least one stoppage per planning horizon. (:{n}_{s}) denotes the maximum index of (:i), which corresponds to the ratio of the planning horizon to the sum of the shortest operating duration and stoppage duration, as expressed in Eq. (4). Similarly, Eq. (5) describes the sequence of 1-run lengths, which represents the durations of the operating periods. where, (:{text{t}text{o}}^{text{i}}) denotes the length of the i-th 1-run (operating duration). (:{text{t}text{o}}^{text{i}}times:varDelta:text{t}) represents the continuous operating duration. Its minimum value must not be less than the lower bound of a single well operating duration (:{text{T}}_{1,text{o}}). Its maximum value is defined as the difference between the planning horizon (:T) and the lower bound of a single well stoppage duration (:{text{T}}_{1,text{c}}). The parsing process for the optimization parameters is as follows: first, given the initial state, the alternating on-off sequence of the well is determined. Then, following this sequence, the corresponding run lengths are sequentially extracted from the 0-run length sequence and the 1-run length sequence to construct the on-off schedule. Assuming that the initial state is 1 (i.e., start), the parsing result is illustrated in Fig. 3. Schematic of optimization parameter parsing based on 0–1 RLE. Previous studies19,20,23 have described optimization parameters via binary encoding, referred to as 0–1 state encoding. During the optimization process, the durations of consecutive operating and stoppage periods were accumulated and evaluated to determine whether they satisfy the engineering constraints on minimum continuous operating and stoppage duration. If the constraints are not met, a new solution must be generated. In contrast, the 0–1 RLE method proposed in the study explicitly defines the allowable range of operating and stoppage durations. This approach internalizes the engineering constraints on continuous operating and stoppage periods, effectively preventing the generation of infeasible solutions and significantly improving both the feasibility probability and optimization efficiency. Assuming a planning horizon of 24 h and a basic scheduling unit of 10 min, with both the minimum continuous operating and stoppage durations not less than 60 min, the optimization parameters based on 0–1 state encoding are shown in Fig. 4, and the solution space size is (:left|Bright|={2}^{144}). Example of an optimization parameter structure based on 0–1 state encoding. The optimization parameters based on the 0–1 RLE are shown in Fig. 5(a). The initial state is 0, indicating a stopped state, which results in a on-off sequence of 010101. First, the value 51 is extracted from the 0-run length sequence, representing 51 basic scheduling units of stoppage, i.e., a stoppage duration of (:51times:10/60=)8.5 h. Then, the value 46 is extracted from the 1-run length sequence, indicating 46 units of operation, i.e., an operating duration of (:46times:10/60approx:)7.67 h. This process is repeated alternately until the cumulative duration of all stoppages and operating durations reaches 144 units. The final state in this example is 1 (i.e., operation) with a duration of 18 units, which is truncated to 17 to ensure that the total duration fits the planning horizon. The decoding process of the optimization parameters is illustrated in Fig. 5(b). Example of a optimization parameter structure base on 0–1 RLE. (a) Example of optimization parameters, (b)Example of optimization parameter parsing. The initial state has two possible values: 0 or 1. Both the 0-run length sequence and the 1-run length sequence contain 12 parameters, each with a value ranging from 6 to 138. Therefore, the size of the solution space is denoted as (:left|text{E}right|=2times:{133}^{24}). This structure focuses only on the head portion of the 0–1 run-length sequences whose cumulative length equals 144 (the planning horizon), whereas the remaining tail beyond 144 does not affect the evaluation of the objective function (let the size of this restricted solution space be denoted as (:{text{E}}^{{prime:}}), clearly, (:{text{E}}^{{prime:}}subseteq:text{E}). From the perspective of set inclusion and order of magnitude, (:left|{E}^{{prime:}}right|le:left|Eright|), and (:left|Eright|gg:left|Bright|). Since only the head portion of the sequence summing to 144 is relevant, it generally holds that (:left|{E}^{{prime:}}right|le:left|Bright|), meaning the solution space constructed based on the 0–1 RLE under the constraint of cumulative on-off duration is smaller than that based on 0–1 encoding. The objective functions, given in Eqs. (6) and (7), minimize grid electricity consumption per unit fluid production and maximize the renewable energy share rate, while ensuring the energy consumption requirements of oil well production. where, (:{c}_{elec}) denotes the grid electricity consumption per unit fluid production, which is calculated as the ratio of the total grid electricity consumed (:{E}_{grid}^{T}) to the fluid production (:{Q}^{T}) over the planning horizon, (:text{k}text{W}text{h}/{text{m}}^{3}). (:{alpha:}_{green}) represents the renewable energy share rate, and the proportion of PV electricity consumed (:{E}_{green}^{T}) relative to the total electricity consumption (:{E}^{T}) of the well. (:{Q}^{T}) is the total oil production during the period, as expressed in Eq. (8) (:{text{m}}^{3}). (:{E}^{T}) is the total electricity consumed, given in Eq. (9), the sum of consumed grid electricity (:{E}_{grid}^{T}) and consumed green electricity (:{E}_{green}^{T}), (:text{k}text{W}text{h}). (:{E}_{grid}^{T}) is the cumulative grid electricity consumption, (:text{k}text{W}text{h}). (:{E}_{green}^{T}) is the cumulative PV power consumption, (:text{k}text{W}text{h}). where, (:{Q}^{t}) denotes the cumulative oil production of the well in the t-th time period, (:{m}^{3}). where, (:{E}^{t}) denotes the cumulative electricity consumption of the oil well in the t-th time period, (:text{k}text{W}text{h}). The single-well dynamic evolution model is constructed by sequentially connecting a series of well dynamic simulation submodels for the basic scheduling unit, as presented in Eq. (10), and dividing the planning horizon into multiple discrete time steps based on the basic scheduling unit. The output of the former simulation at a basic scheduling unit serves as the input for the subsequent time step, enabling an accumulative and iterative evolution process (see Fig. 6). Dynamic evolution model of an oil-pump well. where, (:{h}_{1}^{t}) denotes the initial submergence depth of the oil well at the t-th time period, m. (:{h}_{2}^{t}) represents the final submergence depth at the t-th time period, m. (:f) is the dynamic simulation model of the oil well for the basic scheduling unit, which calculates the cumulative oil production (:{Q}^{t}), final submergence depth (:{h}_{2}^{t}), instantaneous power (:{P}^{t}), and cumulative electricity consumption (:{E}^{t}) during that period, based on the initial submergence depth (:{h}_{1}^{t}), simulation duration (:{Delta:}text{t}), and stroke frequency (:{N}^{t}). To ensure the long-term and stable exploitation of oilfield resources, the oil production of each well is subject to explicitly defined upper and lower bounds within a given time frame. The single-well daily production constraint is formulated in Eq. (11). Here, (:{Q}_{1}^{T}) denotes the lower bound of oil production for the well during planning horizon (:T), (:{m}^{3}), and (:{Q}_{2}^{T}) represents the upper bound of oil production during the same period, (:{m}^{3}). The management system stipulates that the pump submergence must meet the minimum threshold constraint, as given in Eq. (12). where, (:{h}^{t}) denotes the real-time submergence depth of the oil well at the t-th time period, m, and (:{h}_{min}) represents the minimum allowable submergence depth of the oil well, m. The on-off duration constraints for a well include: the minimum operating duration constraint, the minimum stoppage duration constraint, and the total operating duration constraint over the planning horizon. The minimum operating duration and stoppage duration constraints for each cycle are defined in Sect. 2.1 and are thus omitted here. The total operation duration constraint requires that the cumulative operating duration of each well during the planning horizon falls within a reasonable range, as expressed in Eq. (13). where, (:{O}_{2}) and (:{O}_{1}) represent the upper and lower bounds of the cumulative operating duration of the oil well during the planning horizon (:text{T}), respectively, min. Genetic algorithm (GA) is capable of robust global search, high flexibility, and strong robustness, and not reliant on the derivative of the objective function. It has demonstrated significant advantages in multimodal, nonlinear, discrete, and high-dimensional optimization problems, and has subsequently become a prominent method for complex optimization challenges24. The search process of the genetic algorithm is analogous to the optimization of the intermittent pumping well schedule. In the crossover operation, the operation schedule is encoded as chromosomes. The advantageous genes are preserved based on business logic, ensuring their retention in offspring through inheritance. In the mutation operation, targeted perturbations are applied to the current working schedule. The Gaussian mutation extends high-fitness gene segments, while the arithmetic crossover aggregates inefficient genes, thereby achieving a balance between local search and global exploration. For selection mechanisms, both genetic algorithms and intermittent pumping well schedule optimization adopt an elite retention strategy based on fitness evaluation, thereby achieving progressive optimization through iterative feedback loops. Notably, both mechanisms strictly adhere to the convergence criteria. This similarity suggests that by drawing on the crossover, mutation, and selection mechanisms of genetic algorithms—through schedule recombination and local innovation, supplemented by objective function evaluation and screening—systematic optimization of the operation schedule can be achieved, enhancing the efficiency and quality of schedule formulation. As a classic algorithm in the field of multiobjective optimization, NSGA-II has achieved widespread success in engineering applications25. However, the conventional NSGA-II deploys generalized initialization, crossover, and mutation mechanisms, thereby neglecting to fully account for the distinctive characteristics and intricacy of intermittent pumping well operation schedules. This phenomenon leads to a decline in the rate of convergence and an increase in the difficulty of attaining near-optimal operation schedules within constrained timeframes. To address this issue, this study deeply incorporates the operational characteristics of intermittent pumping wells and the source-load matching requirements into the algorithm design. By employing a customized initialization strategy, as well as improved crossover and mutation operators, the NSGA-II algorithm is systematically optimized (see Fig. 7), enhancing its solution efficiency and applicability in intermittent pumping schedule optimization. Flow of the NSGA-II. The population initialization strategy constitutes the fundamental principle upon which the genetic algorithm is based. The initialization solution set, which simultaneously exhibits diversity, feasibility, and representativeness, establishes an efficient search foundation for subsequent evolution. The extant research suggests that knowledge-guided initialization has the potential to increase the convergence speed by 20–40%26. This study integrates domain knowledge (original on-off strategy) and dynamic response factors (such as PV energy fluctuations) by employing a hybrid initialization strategy: (1) Benchmark group (20% of the population): generated by encoding the original schedule to establish a baseline; (2) Renewable-adaptive group (80%): constructed according to PV energy fluctuation patterns to reflect environmental adaptability. The discrete scheduling method is designed based on the optimization parameter definitions (see Sect. 2.1). The fundamental scheduling unit is used to divide the whole operational duration into multiple discrete time segments. The state of each segment is defined as 0 (stopped) or 1 (running). To prevent pump-off events during intermittent pumping well operations, when a fundamental scheduling unit contains mixed states (e.g., running in the first part and stopped in the latter part), the unit’s state is designated as 0 (stopped). Considering a single day with a 10-minute fundamental unit, it discretizes a 144-element binary state array (0–1). The lengths of the corresponding runs (either 0-runs or 1-runs) are calculated for 0–1 run-length encoding. Subsequently, the initial solution is constructed following the definition of the solution space. To illustrate this, the working schedule of an oil well is a cycle of 3.08 h of operation and 3.13 h of shutdown, with a minimum duration of one hour for both shutdown and operation. The corresponding transformation process of the initial solution is shown in Fig. 8. Transformation process of the initial solution based on the original operating schedule. The conventional random initialization yields solutions with limited compatibility with the fluctuation characteristics of PV power, as evidenced by experimental findings that exhibit an average correlation coefficient less than 0.3. It results in the sluggish convergence of optimization algorithms and the system’s renewable energy utilization rate. To address this issue, an intelligent initialization strategy is proposed that incorporates the fluctuation characteristics of PV power generation. First, with the objective of maximizing the proportion of renewable power consumption during operation (Eq. 14), a PV power fluctuation-operation schedule matching model is established with the constraint of temporal alignment between green power and the on-off sequences of intermittent pumping wells. This method innovatively integrates the volatility characteristics of renewable energy into the initial solution generation process of the optimization algorithm, thereby laying a foundation for subsequent precise and rapid optimization. where, (:{U}^{t}) represents the state of the oil well during the designated time period (:t), 0 means shutdown, 1 means operation. (:eta:) is the proportion of renewable power consumption during the operation period. Second, the Pearson correlation coefficient (see Eq. 15) is introduced as an evaluation metric for solution quality to screen candidate solutions with high compatibility with PV power fluctuations. Experimental results demonstrate that the optimized solution set achieves an average correlation coefficient obove 0.67. Where, (:{uprho:}) represents the correlation coefficient between the on-off schedule and the PV power fluctuation. (:{P}_{green}^{t}) denotes the real-time power output of photovoltaic generation in a given period (:t), kWh. (:stackrel{-}{{P}_{green}}) indicates the average power output of photovoltaic generation, kWh. (:stackrel{-}{U}) is the average state value. Finally, the particle swarm optimization (PSO) algorithm is implemented to maximize the objective function (:{upeta:}) under specified threshold (:{uprho:}) constraints, with the top 20% high-quality solutions retained to efficiently generate the initial solution set. The crossover operation of conventional genetic algorithms exhibits insufficient adaptability when applied to the optimization model in this study. First, the optimization parameters possess specific structural properties—including the initial state, the 0-run length, and the 1-run length—the standard crossover operators lack domain-specific guidance mechanisms, making it difficult to perform directed search on high-quality solutions and easily disrupting functionally significant gene structures. Second, the lack of a coordinated protection mechanism between state positions and run-length positions makes the algorithm prone to being trapped in local optima as iterations proceed, suppressing deep exploration of the solution space and resulting in a significant decrease in search efficiency. To address these challenges, two specialized crossover operators are designed: a crossover based on photovoltaic-matching key gene preservation and a crossover based on parents accumulation. The maximum value distribution in the operational duration sequence of the solution must correspond to photovoltaic output patterns, and this extremum serves as the cut point for identifying and extracting key gene segments. Comparing the cut point values (1-run length (operational duration) peaks) between the two parents, the parent solution exhibiting the larger peak value is designated as Parent 1, while the other is assigned as Parent 2. The offspring’s leading sequence is to inherit the key gene segment from Parent 1, comprising the following elements: the initial state, the 0-run-length sequence, and the 1-run-length sequence before the cut point. The subsequent non-key gene is extracted from Parent 2’s post-cut gene fragment, thereby completing the directed crossover operation. If the cut points of the parent solution demonstrate positional discrepancies, then take the minimum values from the constraints of the 0-run-length and 1-run-length sequences are taken as completion (for comprehensive implementation details, refer to Fig. 9). The proposed operator generates new offspring that preserve key genes, which results in high photovoltaic matching, enables effective genetic transmission and significantly enhances the convergence speed. Schematic diagram of the key gene preservation crossover strategy. Optimizing the schedule of intermittent pumping wells involves optimizing multiple operation-shutdown durations. The value of each operation-shutdown duration is constrained within a corresponding range. This range is inversely proportional to the length of the basic scheduling unit. It is also positively correlated with the length of the planning cycle. As previously discussed, this results in an enormous solution space. If the operation-shutdown durations are scaled randomly, numerous infeasible solutions will be generated that violate engineering constraints, significantly impairing the search efficiency of the optimization algorithm. Therefore, an offspring generation mechanism based on parent-value accumulation is designed (Eq. 16), which uses stochastic weighting to increase the rate of feasible solutions produced. Parents with identical initial states are randomly paired. For each pair, new offspring are generated through the weighted accumulation of the 0-run length sequences (shutdown duration series) and the 1-run length sequences (operation duration series). where, (:C) represents the offspring solution, which inherits the initial state from Parent 1. (:{P}_{1}) and (:{P}_{2}) donate the run-length sequences of Parent 1 and Parent 2, respectively. (:{upalpha:}) is a stochastic weighting coefficient controlling parental contribution. If the run-length sequence of the offspring (:text{C}) exceeds the permissible bounds, boundary correction is applied to rectify any invalid elements in the sequence. In GA, mutation is a critical mechanism for maintaining population diversity and directly determines the algorithm’s capacity to escape local optima. Conventional mutation (e.g., uniform or Gaussian mutation) has two notable limitations. It fails to adequately consider the feasible solution space of the intermittent well pumping schedule. The other is that the design for operational contexts involving renewable energy consumption is lacking. This study innovatively proposes two mutation mechanisms that incorporate the characteristics of renewable generation volatility, peak-oriented forward/backward fine-tuning mutation, and off-peak random neighborhood merge mutation. The mutation mechanisms efficiently explore the solution space through the synergistic interaction of peak-phase intensification and off-peak optimization. Forward/backward fine-tuning is employed, centered on peaks within the 1-run length sequences (operating durations), to extend the peak regions via small-step adjustments. As illustrated in Fig. 10, this operator accumulates short periods before and after operating peaks with the peak itself, which effectively increases the intensity of energy consumption during periods of high renewable availability, thereby maximizing the utilization of green power. This directed mutation mechanism maintains operational continuity while significantly enhancing search efficiency. Schematic of peak-guided forward/backward fine-tuning mutation. A small-step accumulation is implemented during the periods of grid power supply, as illustrated in Fig. 11. The number of valid solutions increases while ensuring production constraints by stochastically merging operation-shutdown segments before and after peaks, thereby reducing the frequency of operation-shutdown. It ensures that solutions are feasible while significantly reducing the risk of equipment degradation. Schematic of random neighbor merging mutation in non-peak regions. To verify the feasibility of the model and the improved algorithm, an experimental scenario was constructed based on oil well production data from eastern China. The detailed parameters are listed in Table 2. The reservoir production performance was characterized via the Vogel IPR with key parameters including formation static pressure, flow pressure, and the corresponding formation fluid delivery capacity, shown in Fig. 12 (a) and (b). An oil well system is designed with 2.4 strokes per minute (SPM) and a maximum surface liquid discharge capacity of 14.64 (:{text{m}}^{3}/text{d}), exceeding by 99.5% the formation’s maximum liquid delivery capacity of 7.34 (:{text{m}}^{3}/text{d}). It is set with an intermittent schedule (3.08 h on, 3.13 h off), with the submergence depth ranging between 50 m and 150 m, resulting in a daily fluid production of 6.74 (:{text{m}}^{3}/text{d}) with an energy consumption of 73.79 kWh/d (including 52.37 kWh from grid electricity and 21.42 kWh from PV electricity). Real-time production process of the oil well system under the original operating schedule. The real-time production process of the oil well system is illustrated in Fig. 12(c-f), with an initial submergence depth of 100 m and the system starting in an operating state. Owing to the formation liquid supply capacity being significantly lower than the system discharge capacity, the submergence depth continuously decreases during operation and gradually recovers during shutdown periods, as shown in Fig. 12(c-d). The system operates cyclically based on a fixed on/off schedule. Taking typical summer PV generation in eastern China as an example, a 24 kW PV unit is designed, with a maximum daily output of 73.78 kWh/day, as shown by the red curve in Fig. 12(e-f). The oil well power consumption is over on a stroke, as shown in Fig. 12(f). Under the original schedule, the green power absorption rate is 29.03%, and the grid electricity consumption per unit fluid production is 7.77 kWh/m³. Four sets of comparative experiments are conducted on the NSGA-II algorithm and its improvements, (1) the original NSGA-II, (2) an improved NSGA-II with initialization strategy (IGAWI), (3) an improved NSGA-II with initialization strategy and crossover operator (IGAWIC), and (4) an improved NSGA-II with initialization strategy, crossover operator, and mutation method (IGAWICM). The optimization code was developed in Python 3.9 and executed on a workstation equipped with a 12th Gen Intel® Core™ i7-12700 F processor, 32 GB RAM, and Windows 10 operating system. Each experiment was independently replicated 30 times, and the mean, standard deviation, coefficient of variation (CV), and median were calculated for the grid electricity consumption per unit fluid production, as listed in Table 3. The series of enhancements to the NSGA-II exhibits substantial optimization effects on performance metrics. As the enhancements are progressively applied from the original version to the addition of the initialization strategy, then the crossover operator, and finally the mutation method—the mean and median values show an overall decreasing trend. For instance, the mean decreases from 6.67 (original) to 4.89 (an improvement of 26.69% in solution accuracy), while the median decreases from 6.75 to 4.91. It suggests that the algorithm successfully evades suboptimal local minima and converges toward superior solutions. Furthermore, a decline in both the standard deviation and the CV is observed. The standard deviation exhibited a substantial decrease of 69.56% from 0.69 to 0.21. Concurrently, the CV decreased by 58.15%. The enhanced algorithm demonstrates diminished dispersion and a significant enhancement in stability. The findings indicate that the incremental integration of improvements, namely the initialization strategy, the crossover operator, and the mutation method, consistently enhanced the output consistency and convergence of the NSGA-II. The IGAWICM delivered more stable and efficient results, effectively boosting the algorithm’s overall performance. The distribution characteristics of the solutions and fitness values during the iterations were analyzed, taking the solution process of representative cases from each experimental group as an example, as depicted in Fig. 13. Real-time production process of the oil well system under the new operating schedule. Figure 14(a) shows the variation in the proportion of infeasible solutions. The infeasible solution ratio is the proportion of invalid solutions generated by the algorithm during iterations. It reflects the algorithm’s ability to produce feasible solutions. When the traditional NSGA-II is used as the baseline, the ratio of infeasible solutions exceeds 80% in the first 10 iterations, indicating low efficiency in generating feasible solutions during the early stage. Although this ratio then decreases sharply, significant fluctuations persist, revealing insufficient algorithmic stability. To IGAWICM, the ratio of infeasible solutions in the early stages decreases significantly, effectively suppressing infeasible solutions. It shows that enhanced initialization and other operations accelerate the generation of feasible solutions and improve the convergence speed of the algorithm. The optimization process data. Figure 14(b) shows the Hamming distances of the optimization parameters. The solution based on 0–1 RLE was transformed to 0–1 encoding. Then the pairwise Hamming distances between solutions at each iteration were computed and averaged. The Hamming distance indicates the solution diversity and convergence trends. Larger distances indicate dispersed solutions, whereas smaller distances signify convergence towards optima. In the baseline NSGA-II, the Hamming distance of solutions fluctuates violently during optimization, peaking at the 12th iteration before declining sharply. It indicates unstable solution diversity. By contrast, theIGAWICM (purple curve) gradually decreases the in Hamming distance before stabilizing, indicating that the improved algorithm effectively avoids premature convergence while maintaining diversity. It confirmed the superior convergence efficiency and refined solution clustering capability of the enhanced algorithm. Figure 14(c) presents the distribution of grid electricity consumption per unit fluid production. The traditional NSGA-II (blue curve) shows high grid electricity consumption during the initial iterations, which remains elevated compared with the improved ones even after a reduction. By contrast, the IGAWI, IGAWIC and IGAWICM rapidly reduces grid electricity consumption, stabilizing at significantly lower levels, with the IGAWICM demonstrating the best performance. The improved NSGA-II achieves a better balance between fluid production demand, PV energy utilization, and grid electricity consumption, thereby improving the system’s overall economic performance. Figure 14(d) displays the distribution of green power absorption rate. The traditional NSGA-II achieves a suboptimal green power absorption rate, whereas the improved methods demonstrate an increase in absorption rates with each iteration. The IGAWICM proves to be the most effective enhancement, delivering superior efficiency and stability in terms of green power absorption. The IGAWICM significantly outperforms the traditional NSGA-II algorithm in several key areas: reducing the proportion of infeasible solutions, avoiding premature convergence, accelerating algorithm convergence, decreasing grid power consumption, and improving green power absorption rates. These results validated the effectiveness of the improvements for the green power absorption and power consumption optimization scenario, providing a practical and feasible approach to optimizing algorithms in related fields, such as integrating renewable energy with oil well operational systems. The enhanced NSGA-II algorithm, informed by domain expertise, is used to optimize the on/off schedules of intermittent pumping wells. The parameters of the algorithm are enumerated in Table 4. The search efficiency of the algorithm is enhanced by an initialization strategy, crossover operator, and mutation method, given the intermittent operating characteristics of oil wells and the fluctuation characteristics of PV power. High-quality solutions can be obtained with 30 individuals and 30 generations, with the computation time kept below 10 min. Compared with extant studies (population size of 2000 and 500 generations)19, by improving the definition of optimization parameters through run-length encoding and incorporating green power fluctuation characteristics to guide the genetic algorithm’s search process, the population size is reduced by approximately 67 times and the iterations by 17 times. This results in an over 1000-fold improvement in computational efficiency while maintaining convergence accuracy. The finding indicates that the enhanced algorithm has a substantial advantage in terms of its capacity to expedite the resolution process. The fitness values of individuals across iterations are shown in Fig. 15. The proposed initialization strategy enables the algorithm to identify a near-optimal operating scheme in the first iteration, reducing the grid electricity consumption per unit fluid production from 7.7 kWh/m³ (under the original scheme) to 7.5 kWh/m³. As the number of iterations progress, the enhanced crossover and mutation operators preserve key gene segments while enabling fine-tuning and recombination. It results in a continuous decline in grid electricity consumption per unit fluid production and a steady increase in green power utilization. Consequently, the algorithm rapidly converges to high-quality solutions. Distribution of solutions throughout all iterations. Since this study addresses a multi-objective optimization problem, the solution process yields multiple Pareto-optimal solutions, from which the selection criteria can be customized according to practical requirements. In this paper, the solution with the minimum electricity consumption per unit liquid production is preferentially chosen under the constraint of achieving the lowest power curtailment rate. Figure 5(a) presents the optimal results of this case study, whereas Fig. 5(b) illustrates the process of converting the optimized parameters into operational regimes (previously detailed, omitted here). The dynamic parameters, including the flow pressure, submergence depth, and power consumption, are exhibited under the new operational schema, as illustrated in Fig. 13. After optimization, the intermittent pumping regime is no longer constrained to a conventional fixed-cycle pattern (see Fig. 13c-d), nor is the submergence depth variation confined to a fixed range (Fig. 13a-b). Instead, by enabling dynamic adjustment of load distribution through variable-cycle intermittent pumping within a reasonable submergence depth, the system better adapts to the fluctuations of PV power. The new schema consolidates non-operational periods by shifting them forward to non-green-electricity intervals and delays production phases to periods of abundant green power supply. The wellbore liquid storage ensures that there is an adequate supply of fluid during periods of high green power. Consequently, the well transitions from its initial operating state to an 8.5-hour shutdown. When the submergence depth is 327.57 m, the pumping system commences continuous operation for 7.7 h, from 8:30 a.m. to 4:15 p.m. The submergence depth diminishes to 51.18 m, which approaches but remains above the minimum limit of 50 m, and the system undergoes a shutdown process to avert pump-off. In periods of transition in proximity to green-power intervals, intermittent pumping employs minimal cycle durations (1-hour operation/1-hour shutdown) to maximize green power consumption. During periods of non-green electricity, the system is set to minimize the frequency of on-off operations, with a shutdown duration of 3 h and an operation duration of 2.8 h, allowing the wellbore to accumulate sufficient liquid while maintaining the minimum production. A comparative analysis of the renewable energy share rate, the grid electricity consumption per unit fluid production, the actual grid electricity consumption, and the total green power utilization between the original and optimized operational schedule is presented in Table 5. Operating with the optimized schedule results in an approximate 101% increase in green power absorption, alongside a decrease of approximately 41% in grid electricity consumption per unit fluid production and actual grid electricity consumption. Furthermore, the fluid production increases by 0.29%. The optimized schedule saves 21.73 kWh of grid electricity per operating day, resulting in an annual reduction of nearly 8,000 kWh. Assuming a grid electricity price of 0.5 CNY/kWh, the annual cost savings would be approximately 4,000 CNY. There are no pump-off events while maintaining stable production under the new schedule. The synchronization of operation duration with green power volatility has been demonstrated to enhance renewable energy absorption, reduce grid electricity consumption, and improve economic efficiency. The method proposed in this study can be extended to oilfields that combine PV generation with intermittent production modes due to insufficient formation fluid supply. By automatically adjusting the operating schedule of intermittent wells in real time according to the fluctuation characteristics of green power, this approach not only enhances the local consumption of green electricity during oil and gas production and alleviates the operational stress on regional grids caused by high penetration of variable renewable energy, but also significantly reduces oilfield dependence on grid electricity, leading to substantial cost savings. This strategy provides a practical technical pathway for oilfield operators to promote green power substitution and optimize energy consumption structures, contributing to both improved economic performance and low-carbon development. From a broader perspective, the integration of variable power supply with interruptible load scheduling propo1ed in this study helps mitigate challenges faced by grid operators when integrating green power. It also offers guidance for policymakers in designing localized incentives for industrial green power applications, and provides a reference for energy developers and other stakeholders to explore the synergy between renewable energy generation and flexible electricity demand in different regions. This approach is adaptable to various scenarios – for example, by adjusting the parameters of power fluctuation, it can be applied in regions with high wind power penetration, and it can also be extended to flexible industrial loads beyond oil extraction – thus demonstrating broad practical applicability. In response to the challenge of optimizing intermittent pumping well schedules under the variability of green electricity in source-load matching scenarios, this study designs a multi-objective optimization model with the objectives of maximizing the green electricity share and minimize grid electricity consumption per unit of liquid production. A 0–1 run-length encoding method was proposed for defining optimization parameters, which, compared with the conventional 0–1 state encoding, effectively reduced the solution space size and decreased the probability of generating infeasible solutions, providing a novel parameter modeling approach for intermittent oil production scheduling. Building on this, a self-evolving optimization method for intermittent pumping schedules guided by photovoltaic power fluctuations was designed and integrated with the NSGA-II algorithm, with targeted improvements to key operators including initialization, crossover, and mutation. By introducing an initialization strategy that fuses the original schedule with PV energy fluctuation characteristics, the proportion of infeasible solutions decreased from 93.33% to 56.67%, a reduction of 39% points. The design of a key-gene-preserving crossover method based on green power matching and an accumulative crossover operator based on parent values further reduced the infeasible solution ratio to 36.67%, significantly enhancing the preservation of high-quality genes and search efficiency. Meanwhile, peak-guided forward/backward fine-tuning mutations and random-neighbor merging mutations in non-peak periods were implemented to escape local optima and improve solution quality and diversity. For ultra-large-scale solution spaces ((:{2}^{144})), the proposed method required only 30 populations and 30 generations, less than 10 min to obtain high-quality solutions that meet engineering requirements, achieving over a thousandfold improvement in computational efficiency. Using typical oil well data as an example, grid electricity consumption per unit liquid production decreased from 7.77 (:text{k}text{W}text{h}/{text{m}}^{3}) to 4.53 (:text{k}text{W}text{h}/{text{m}}^{3}), and the share of renewable energy increased by more than twofold, significantly enhancing green power self-consumption and demonstrating the practical effectiveness of the proposed method. In summary, this paper presents an optimization approach that leverages the characteristics of renewable power fluctuations to guide the targeted improvement of key genetic algorithm operators. The method achieves self-evolving optimization of intermittent pumping schedules under a fitness supervision mechanism, providing a novel solution paradigm for source-load coordinated scheduling in renewable energy scenarios. Future research may further explore adaptive integration mechanisms between engineering constraints and genetic operators, investigate patterns of formation fluid supply and well power characteristics, and facilitate efficient application of this approach in complex scenarios, such as wind-solar complementarity and multi-well schedule optimization.
