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 optimisers 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.
Premature inverter failure – 4.2 GW of capacity will be affected this year, says analyst
U.S.-owned business intelligence firm Wood Mackenzie has attempted to evaluate the market opportunities offered by the repowering of solar projects around the world which feature inverters which are 10 years old – as well as those which will expire ahead of time.
