One of the best things about residential solar panels is their long lifespan. Solar panels aren’t something that’s going to break down and stop working just a few years after you install them like so many things these days. They are built to last for decades, which is part of the reason they’re such a smart long-term investment.
Average Lifespan of Solar Panels
Most solar panels are warrantied for 25-30 years, and can last 10+ years longer. After your solar panels hit the 25 or 30-year mark, they won’t just stop working entirely. Instead, the level of annual degradation something called solar panel degradation is no longer warrantied.
Solar panel degradation is a reduction in output which causes them to produce less and less electricity over time. It happens very slowly—According to the National Renewable Energy Laboratory (NREL), most solar PV panels have a degradation rate of just 0.5 percent per year after the first year. Depending on the rate of degradation most panels will still be producing between 86% and 92% of their original power output after 25 years, which is pretty remarkable.. After that, they still have plenty of life in them.
Solar Panel Warranties
Most solar panels have a 25-year warranty to ensure their lifespan. Of course, warranty lengths can vary from one manufacturer to another, but 25 years is the industry standard. Solar Energy Solutions installs premium solar panels that have been carefully engineered for durability and tested to ensure a long solar panel lifespan. We’re happy to offer solar panel with a 25-30 year output warranty and an additional workmanship guarantee.
