Are residential PV inverters durable?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.
What are the oldest inverters used in PV systems?“The oldest inverters investigated in this study are from the early 1990s,” they said. The survey includes data from 1,195 PV systems with 2,121 inverters and 8,542 optimizers. The biggest share of the inverters used in these systems had power ratings between 10 kVA and 15 kVA.
How reliable is an inverter?They said the overall reliability of an inverter is proportional to the reduction in the number of power electronic components. In inverters with power optimizers, the first fault often occurs earlier than in devices without optimizers, according to the scientists.
Do old inverters have a survival curve?“However, because only little data is available for old inverters, the uncertainty in the survival curve increases with increasing inverter life,” said the scientists. The survey showed that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operati
