All solar panels slowly degrade over time, which means they’re producing less electricity from the same amount of sunlight. How and why does this happen? Various external factors (like weather) wear down on the panels and negatively impact their ability to produce electricity. One way solar panel degradation happens. .
There are many different factors that contribute to solar panel degradation rates, but many of them focus on something that’s pretty hard to control - the weather. .
On average, solar panels degrade at a rate of 1% each year. The solar panel manufacturer’s warranty backs this up, guaranteeing 90%. .
