renewable energy test center

In this year’s ultraviolet-induced degradation (UVID) testing, engineering advisory and test services provider Renewable Energy Test Center (RETC), has noticed that 40% of modules tested have returned with a red-flag result.

Following a decade of technological innovation and geopolitical challenges, PV Tech Power revisits the issue of module quality.

Hail represents a significant threat to PV modules, more so as climate change increases the potential for severe storms.

US-headquartered engineering and consultancy firm Black & Veatch and engineering services, and certification testing lab, Renewable Energy Test Center (RETC) in California, said they would establish the first of its kind bifacial solar module ranking service.
