Field-tested hurricane survival strategies for solar
Rocky Mountain Institute (RMI) has published “Solar Under Storm III,” analyzing hurricane impacts on solar farms in the Caribbean after Hurricane Beryl and identifying key failure modes and risk-mitigation measures.
Remedies for PV curtailment in Poland
Solar curtailment is on the rise in Poland, with around 600 GWh of PV capacity reduced during the first six months of 2025. The Warsaw-based Institute for Renewable Energy (IEO) suggests one solution is to support the electrification of Poland’s heating sector with the surplus of PV power.
Expansion of PV for self-consumption reduces grid load
Fraunhofer Institute of Optronics, System Engineering and Image Evaluation – Applied System Technology (IOSB-AST) says Germany’s grid load is falling as more PV output is consumed on-site, but notes rising electrification in other sectors could reverse the trend.
