  • Connecticut Approves Plug-In Solar – It’s So Exciting!

    Connecticut is set to become the sixth state to allow plug-in solar panels, enabling residents to easily add renewable energy to their homes without costly connection agreements with utility companies. The legislation will allow for portable solar panels that can be plugged into household electrical sockets, ideal for renters, apartment dwellers, and those with restrictions on traditional rooftop solar installations. The bill also includes provisions for extending solar programs, establishing new rules for solar use, and implementing incentives for low-income community solar and residential energy storage. This move towards small-scale solar capacity is part of a broader effort to promote the development of residential, agricultural, and corporate solar power in Connecticut, with an aggregate target of 180 megawatts per year starting in 2028, ultimately aiming to lower utility bills, improve system reliability, and expand consumer protection while gradually introducing clean energy solutions.

  • All solar cell efficiencies at a glance – updated

    The Solar Cell Efficiency Tables, led by Professor Martin Green from UNSW, have been updated to Version 68 and will be available as open access in Joule starting from July 2026. The latest results show new efficiency records for large area silicon cells, modules, and lead halide perovskite cells. Progress has also been made with perovskite-silicon tandem cells and modules, indicating a positive trend towards more efficient and sustainable photovoltaic systems. Additionally, Version 67 presented a new record of 27.9% efficiency for an interdigitated-back-contact (IBC) device developed by Longi, showcasing significant advancements in solar cell technology since the tables were first published in 1993. Scientists from various institutions around the world, including the European Commission Joint Research Centre, Germany's Fraunhofer Institute for Solar Energy Systems, and the US National Renewable Energy Laboratory, have contributed to these advancements.

  • Large-load customers can help commercialize new clean energy technology: CEBA

    Large-load customers are turning to clean firm technologies like advanced geothermal and small modular nuclear reactors to power their operations, with the help of clean energy tariffs and bilateral customer-utility arrangements. Hyperscalers like Google and Microsoft are investing in clean energy power purchase agreements, focusing on nuclear, hydropower, and geothermal, to drive the development of new technologies and protect ratepayers. Small modular reactors are attracting investments for future data center operations due to their smaller footprint, and durable clean energy tariff designs are crucial for supporting these initiatives. Partnerships between customers and utilities are leading to innovative solutions, such as in Minnesota where Google and Xcel Energy utilized a green energy tariff to bring online a portfolio of resources including solar, wind, and long duration energy storage, resulting in the largest long duration energy storage system seen so far.

  • German consortium developing aluminum facade elements with integrated PV modules

    Researchers from Germany have developed a PV-activated design facade element with aluminum as the base material, funded by Germany's Federal Ministry for Economic Affairs and Energy. The approach involves directly laminating a PV module onto the aluminum facade element, with challenges such as bending and electrical insulation addressed. The prototypes of the PV-activated facade element differ from a facade element without PV by only two connectors, making them more likely to be accepted and used by installers. Scientists have developed a prototype called BIPV-4 for a façade element that utilizes aluminum-based PV technology, demonstrating that it can match conventional module performance while maintaining safe electrical isolation. The design includes rear junction boxes, insulated cross-connectors, a zigzag 3D structure, golden anodized aluminum, and optimized use of M12 cells. The group also created multiple PV design façade variants with adaptable cell formats, different surface geometries, and customizable color options, allowing for integration into diverse façade geometries and scalable to different module sizes up to 2 meters.

  • State locks in six renewable energy zones after final round of nips, tucks and rethinks

    Victoria has declared five onshore renewable energy zones and one shoreline zone to increase its share of battery-backed wind and solar energy to 65% by 2030 and 95% by 2035. The final design includes zones in South West, Central Highlands, Gippsland, Western, and North West, with the Central North zone still under consideration. Changes were made to the South West and Central Highlands zones based on environmental concerns and land availability. The Gippsland region will host both onshore and shoreline renewable energy zones, with the latter connecting offshore wind farms to the grid. The government considered feedback but not all requests were implemented. The zones aim to balance community concerns with developer interests, utilize strong wind and solar resources near existing transmission lines, exclude areas of high biodiversity value, facilitate the transition away from coal-fired power stations, and ensure better coordination of renewable energy projects. VicGrid is also working on developing guidelines for the next Victorian Transmission Plan to meet the state's transmission and renewable energy generation needs.
