When you’re going solar, you want to make sure your investment lasts. Let’s talk about inverter lifespan. Inverters typically last 10-15 years, but with proper care, they can survive for 20 years or more. Of course, how long your inverter lasts depends on several factors.
While solar panels can last 25 to 30 years or more, inverters generally have a shorter life, due to more rapidly aging components. A common source of failure in inverters is wear and weathering on the capacitors in the inverter. The electrolyte capacitors have a shorter lifetime and age faster than dry components, said Solar Harmonics.
String Inverters typically last 10-15 years. They are the oldest technology, but still reliable. Warranties range from 5-10 years, hinting at their lifespan. Microinverters have a more extended life expectancy, generally around 20-25 years. Most come with 25-year warranties, reflecting their durability.
Typically they are less expensive, said Solar Reviews. Inverters can typically cost 10-20% of the total solar panel installation, so choosing the right one is important. While solar panels can last 25 to 30 years or more, inverters generally have a shorter life, due to more rapidly aging components.
Microinverters have a longer life. EnergySage said they can often last 25 years – nearly as long as their panel counterparts. Usually, these inverters have a 20 to 25-year standard warranty included.
Regular maintenance and professional assistance are key to maximizing the lifespan of solar inverters and, consequently, reaping the full benefits of clean, renewable energy. Which Solar Inverters Should I Use?
