Solar power has agreed to the takeover Ambia Solara solar installation company based in Lindon, Utah. SunPower will buy Ambia for $37.5 million in equity. The transaction is expected to close before the end of the year. According to Ohm Analytics, Ambia is among the top 20 solar installers in the country based on installed megawatts. Based on three-quarters of actual results and with one month left in Q4 2025, Ambia’s estimated 2025 revenue forecast is $83.6 million. The corresponding estimated 2025 revenue guidance for SunPower is $303.4 million. After the deal closes, Ambia CEO Conner Ruggio will lead SunPower’s…

Japanese oil giant Idemitsu Kosan and US-based Source Energy Company have announced a collaboration to develop copper-indium-gallium-selenide solar panels and arrays for satellite and space applications. November 11, 2025 Valerie Thompson The BOTAN microsatellite Image: Idemitsu Kosan Idemitsu Kosan, a Japanese manufacturer of oil and chemicals, and Source Energy Company, a US-based manufacturer of components for aerospace solar energy systems, have announced collaboration plans to develop copper-indium-gallium-selenide (CIGS) solar PV arrays for satellite and space applications. The next step in the partnership will be a “rigorous development and testing campaign” at Source Energy Company’s Colorado facility in preparation for implementation,…

Accurate technology cost assumptions are a cornerstone of effective energy transition planning. Although we have been blessed with rapid cost declines in renewable energy technologies, most energy models and policy analyzes remain based on outdated assumptions. A new study by researchers from the University of Canterbury, LUT University, the German Aerospace Center (DLR) and the International Renewable Energy Agency (IRENA): “Are we too pessimistic? Cost forecasts for solar photovoltaics, wind energy and batteries overestimate actual costs worldwide”, published in Applied energysystematically reviewed 40 studies and 150 long-term scenarios for sustainable energy technologies. It compared their expected costs (all adjusted for…

The Chinese manufacturer said the product line includes five models with powers ranging from 25 kW to 50 kW, supporting charging and discharging currents up to 150 A. November 11, 2025 Lior Kahana Chinese energy storage solutions company Solinteg has released a new series of hybrid inverters designed for commercial and industrial (C&I) storage systems, agricultural sites and distributed energy projects. The new M2HTs system is part of the M hybrid inverter family and offers output powers ranging from 25 kW to 50 kW. “The inverters operate with battery voltages from 150 V to 840 V and support charge and…

By Contributing Author November 11, 2025 Until recently, many solar developers relied on long-term options with minimal upfront costs and only closed as a project neared construction. That approach no longer works in many demand regions. Consider land financing as a practical alternative. Two Creeks Solar Farm located in Two Creeks, Wisconsin. Image via Accelerate. By Maria Klutey | Land availability has become an increasing challenge in the development of solar projects. A 2024 report from Paces, a renewable energy project planning software company, found a 22% decline in available land in twelve US states. This constraint now competes with…

Yeoman Solar in Waukegan, Illinois. CleanCapital announced the upcoming completion of two brownfield solar development projects: Yeoman Solar in Waukegan, Illinois, and Little Elk Solar in Elkton, Maryland. The Yeoman solar project, scheduled to be commissioned in late 2025, is a 9.15 MW community solar project built on the Yeoman Creek Landfill Superfund site, a site undergoing environmental remediation. The Waukegan Community Unit School District No. 60 owns the portion of the EPA Superfund site that is being converted into an energy generation hub. The Yeoman solar project, which is participating in the Illinois Solar for All Low-Income Community Solar…

Engineers at Rice University have developed a process that recovers lithium from electric vehicle battery waste using electricity and water, bypassing the need for strong acids and complex chemical steps. The method employs the same reaction as conventional battery charging, driving lithium ions from spent cathodes into water, where they combine with hydroxide to form high-purity lithium hydroxide. Sibani Lisa Biswal explained, “If charging a battery removes lithium from the cathode, why not use that same reaction to recycle?” Using a compact electrochemical reactor, the team efficiently separated lithium and produced the lithium salt preferred by manufacturers. In experiments, the…

Brazil’s Ministry of Mines and Energy says it has opened a public consultation for a battery storage auction in 2026 to contract systems of at least 30 MW that can provide four hours of power daily under a 10-year deal. November 11, 2025 Livia Neves Image pv magazine, Alessandra Neris By ESS news Brazil’s Ministry of Mines and Energy has opened a public consultation on the guidelines and structure for the 2026 LRCAP auction of storage capacity. The announcement was published this week and the consultation lasted 20 days. According to the draft regulation, the auction will contract systems of…

Waaree Energies has entered the rear contact module market with a double-glazed TOPCon module. The new product is based on G12R format cells. November 11, 2025 Emiliano Bellini By pv magazine India Waaree Energies has unveiled a new solar panel based on back contact (BC) and tunnel oxide passivated contact (TOPCon) cell technology. The double-glazed panel uses G12R format cells and has an energy conversion efficiency of 23.88%. It is part of the Tejomay series, which includes double-glazed rear contact modules ranging from 635 W to 665 W with efficiencies between 23.51% and 24.62%. Built using 132 n-type half-cut cells,…

Highview has secured funding to begin work on its second long-term energy storage (LDES) site in the UK.The company has raised £130 million for the first phase of its planned 3.2GWh hybrid LDES solution in Hunterston, Scotland, building a ‘stability island’. The so-called stability island will function independently of the energy storage elements on site and provide the electricity grid with inertia, short circuit and voltage support. Highview chief executive Richard Butland said this will “avoid costly curtailment and maximize the renewable energy we generate in Britain”. Solar energy portal heard that the stability island consists of a flywheel and…
