Scientists in China have investigated how frame perforations can help reduce solar panel operating temperatures through air cooling. Their findings show that the number of perforations must be carefully calibrated, and that more is not necessarily better. November 6, 2025 Lior Kahana A research team led by scientists from China’s Northeast Electric Power University has investigated the impact of frame perforation on lowering the temperature of PV panels using passive air cooling. “Compared to previous studies, the main novelty of this study is the comprehensive effect evaluation of frame perforation on the passive air cooling performance, thermal management and electrical…
The final of pv magazine USA Week 2025 promises an in-depth exploration of the most immediate, multi-faceted solution to America’s escalating energy demand and rising electricity rates: distributed energy. November 6, 2025 Ryan Kennedy By pv magazine USA Titled “Distributed Energy as a Solution,” Day 3 of the virtual conference will demonstrate how rooftop solar, residential storage, community solar and smart grid technologies are not just complements, but the essential building blocks for a more resilient and affordable energy future. As the country anticipates rising electricity demand and associated high tariffs, DE offers a rapid deployment advantage over traditional grid-scale…
Ukraine is changing its state support mechanism for households installing hybrid renewable energy systems to a one-time repayment of 30% of the principal debt. The Ministry of Energy says the change will help increase access to hybrid energy supply systems. November 6, 2025 Patrick Jowett UkraineThe Ministry of Energy has announced changes to the loan scheme for private individuals installing hybrid renewable energy systems. Individuals who install solar or wind systems in addition to storage now benefit from a one-time repayment worth 30% of the loan principal instead of monthly interest payments. A statement from the ministry said the change…
