Degradation issues identified in new cell technologies such as TOPCon and HJT underscore the importance of module stability as well as efficiency. Tom Kenning reports on the testing of next-generation modules and efforts to ensure their longevity in the field.
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.
A record of 53 manufacturers and 388 module types have been named “Top Performers” by Kiwa PV Evolution Labs (PVEL) in its 2024 Module Reliability Scorecard.
