Photovoltaic (PV) inverters convert DC power from solar panels into AC power, crucial for solar setups. Their efficiency significantly impacts overall system performance. By converting power from each solar panel individually, they ensure optimal performance without being affected by others. As the microinverter market grows, establishing standards for evaluation is essential. This article outlines key tests and criteria for assessing durable microinverters.
An extended warranty to get your solar covered
While the performance warranty for PV modules using string inverters can be as long as 30 years, string inverters themselves are generally designed with a 15 year service life in mind. Depending on the inverter design, the materials used, and the installation environment, their actual typical life ranges from 8 to 15 years. That’s a two to four times lifespan difference between the two. In a real life scenario, this means that string inverters are likely to need replacing halfway through the service life of the PV system.
