The lifespan of a solar inverter typically ranges from 10 to 15 years. Inverters play a critical role in converting the DC electricity generated by your solar panels into usable AC electricity for your home. Over time, the components in the inverter may wear out or become less efficient. It’s essential to factor in the eventual replacement of your inverter when planning your solar panel system. Fortunately, inverters are relatively easy to replace, and doing so can rejuvenate your system’s performance.
