How long do residential solar inverters last?
What is the duration of these? Due to components that age more quickly than solar panels, inverters typically have a shorter lifespan of 25 to 30 years or more. Electro-mechanical wear on the inverter’s capacitor is a typical cause of inverter failure.
According to Solar Harmonics, the electrolyte capacitors age more quickly and have a lower lifespan than dry components. According to EnergySage, a centralized home string inverter typically lasts 10 to 15 years, meaning that at some time in the panels’ lifespan, it will need to be replaced.
Most string inverters come with normal warranties of five to ten years, with many offering the opportunity to extend to twenty years. Certain solar contracts come with free upkeep and monitoring for the duration of the agreement, so it is
