Truro Vineyards, a family-owned winery on Cape Cod, partnered with Sunbug Solar, which is now a part of ReVision Energy, to install more than 160 panels on the vineyard’s 4,000-sq-ft distillery warehouse in North Truro, Massachusetts. Credit: ReVision Energy The solar arrays help South Hollow Spirits, the vineyard’s distillery, maintain an optimal storage temperature of 50 to 60° degrees Fahrenheit for rum, gin, whiskey and amaro throughout the year. The system is anticipated to offset more than the full load of the warehouse, with excess production credited to other buildings on site, including the production floor, offices and retail shop.…

GameChange solar energya supplier of solar trackers and racking solutions, had its rack bolt with a rectangular head recognized by UL 2703 from the national testing laboratory, Inter sign. A view of GameChange Solar’s new rectangular head bolt. This patent-pending bolt-on solution is designed to streamline the installation process and strengthen the connection between trackers and solar panels. The new rectangular head bolt is intended to solve problems with wrenching errors caused by extreme winds by mounting a larger bearing surface on the module frame. This bolt design is intended to transfer more force from the module to the rack.…

The research group led by Professor Martin Green has published version 64 of the solar cell efficiency tables. There are 19 new results reported in the new version. July 3, 2024 Emiliano BelliniThis was published by the international research group led by Professor Martin Green of the University of New South Wales (UNSW) in Australia Version 64 of the “Efficiency tables for solar cells” in Progress in photovoltaics.The scientists said they have added 19 new results to the new tables since December.Strong progress was reported across the range of solar cell technologies, including silicon, chalcogenide, organic and perovskite.A major new…

As bifacial modules proliferate, albedo estimates are becoming increasingly important, and because developers are unwilling to install weather stations to assess solar energy resources, on-site measurements by third parties, over periods of as little as a day, have become a popular option. Is this an acceptable compromise between expensive on-site measurements and less accurate satellite data? Stefan Mau from Everoze discusses the potential benefits and limitations of this approach. July 3, 2024 pv magazineFrom pv magazine 24/6Although an accurate assessment of solar energy resources is critical to ensure the reliability of an energy yield assessment, most studies are based solely…

Statkraft will prevent Bracon Ash from generating revenue during negative price periods by using its downregulation service. Image: Statkraft. Renewable energy generator Statkraft has signed a seven-year power purchase agreement (PPA) with Luminous Energy for the latter’s 28.5 MWp Bracon Ash Solar Farm in Norfolk. Luminous Energy has secured fixed energy prices for the majority of the solar farm’s output with a Contract for Difference (CfD) from Allocation Round 5 (AR5) and a virtual corporate PPA with Bristol Airport. According to the developer, the Bracon Ash project is the first to combine these two financial instruments for one solar park.…

Large-scale ground installations saw the greatest growth in 2023 and accounted for almost half of the annual deployed capacity. Image: British Parliament. New solar deployment in Britain is expected to decline year-on-year by 2024 compared to 2023 as installations remain relatively stable across the residential, commercial rooftop and ground-mounted segments, writes Solar Media analyst Josh Cornes. The UK solar market is expected to grow by around 1.5 to 2 GW in 2024, similar to 2023 levels, and will continue on a steady upward growth trajectory since the government introduced incentives for investment in the sector has been abolished. The final…

Chinese in China have used two sulfone-based organic molecules known as diphenyl sulfone (DPS) and 4,4′-dimethyldiphenyl sulfone (DMPS) to passivate absorber defects in perovskite solar cells. The result is a device with a higher electron cloud density at the interface between the perovskite material and the passivation layer. July 3, 2024 Emiliano BelliniA group of researchers led by Zhejiang University of Technology in China has proposed using two sulfone-based organic molecules known as diphenyl sulfone (DPS) and 4,4′-dimethyldiphenyl sulfone (DMPS) to improve the performance of perovskite solar cells.They used the molecules to improve charge distribution at the interface between the…

Construction has begun on a solar and battery-based microgrid that will provide the city of Corryong in Victoria’s northeast with crucial energy resilience, keeping the power on during emergencies such as bushfires and storms. July 3, 2024 David CarollBy pv magazine AustraliaVictorian distributed network service provider AusNet has started construction of an ‘islandable’ microgrid that will integrate a centrally located 4.99 MW/5.2 MWh battery energy storage system and a range of residential solar and battery systems to power Corryong homes, power businesses and community facilities during a network outage.The centralized battery will connect to 33 solar energy systems and batteries…

Scientists have fabricated and analyzed a new coating for semi-transparent photovoltaic glazing that reportedly delivers remarkable energy yield and low heat gain. Through outdoor experiments, the researchers also found that the glazing also provides satisfactory, high-quality indoor lighting conditions. July 3, 2024 Lior KahanaResearchers from Hong Kong University of Science and Technology and Hong Kong Polytechnic University have designed and investigated a new coated semi-transparent photovoltaic (CSTPV) glazing for building-integrated photovoltaic (BIPV) applications.They explained that the novelty of their approach was to equip the glazing with a highly transparent passive radiant cooling coating. “Highly transparent passive radiant cooling paints are…
