Survey shows 34.3% failure rate for residential inverters over 15 years
The Bern University of Applied Sciences in Switzerland has published the initial results of a survey on the durability and performance of residential PV inverters and power optimizers over a 15-year period. They found that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operation.
TBEA unveils new residential inverters
