France’s Solarpro launches steel deck mounting system for rooftop PV
Solarpro has developed a steel deck mounting structure with a drilling-free fixing system for rooftop solar panels.
How the world’s sunniest region tackles solar module soiling, cleaning
Researchers studying PV panels in Chile’s hyper-arid Atacama Desert found that cemented soiling can cause annual energy losses of up to 9.8%. Their combined field and laboratory work shows that dry cleaning leaves residue that accelerates future cementation, making wet cleaning the more effective long-term strategy despite higher costs and scarce water.
Keeping the smart grid cyber secure
As smart grid tech is rolled out around the world to modernize legacy assets and integrate renewable energy generation, it is also making the electricity network more prone to cyber attacks. IEC Standards provide protection but they also are challenged to keep up with the latest threats.
Cooling PV modules with seawater
A research team in India developed a passive solar-panel cooling method using a thin, still layer of seawater placed over the module surface. Tests showed that while a thick water layer sharply reduced energy output, a thin 5 mm layer lowered module temperatures and increased daily energy generation by up to 8.86%.
Panasonic testing PV-driven hydrogen platform in Germany
The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its facility in Munich. The system uses an AI-based energy management system that reportedly makes battery storage unnecessary.
