Western wildfires, storms cut solar gains in the West while Eastern US sees boost
In a new weekly update for pv magazine, Solcast, a DNV company, reports that frontal systems, widespread wildfires and an omega block pattern contributed to highly mixed irradiance anomalies across North America in September. Solar conditions underperformed in much of the West and Midwest, while the Northeast, South, and parts of Canada recorded a strong month.
New research confirms rooftop PV affects urban temperatures, cooling demand
Using Lyon as a case study, an international research team has simulated the effects of rooftop photovoltaic (PV) coverage in an urban area at three levels: 25%, 60%, and 100%. The results have shown that solar panels can raise daytime temperatures by up to 0.72 °C, while cooling nighttime temperatures by up to 0.42 °C. In addition, daytime air conditioning demand has decreased by about 5%.
Brazil imports 10.6 GW of solar modules in H1
Brazil imported 10.6 GW of solar modules in the first half of 2025, down slightly year over year as developers rushed to secure shipments before an import tax hike, according to Greener.
Building-integrated concentrating photovoltaics for vertical applications
An Indian-British research team has developed a building-integrated linear concentrating PV facade by sandwiching an asymmetric compound parabolic concentrator, PERC cells, and encapsulation layers between two sheets of glass. The system was tested under both indoor and outdoor conditions and its payback period was found to be of up to 11 years.
