Solar panel degradation: Don’t worry, it happens naturally

Purchasing solar panels for your home is a long-term investment, as panels are backed by a 25-year warranty and will save the average customer tens of thousands of dollars over that time frame. Just how does that process work? That’s why it’s important to educate yourself about the product and understand the many benefits of solar energy.

One thing you will learn through that process is that solar panels naturally degrade over time, meaning panels lose some of their original capacity to produce power because of factors including ultraviolet light and weather cycles. You try sitting on your own roof for 25 years and see how you perform after a quarter century! And yet solar panels are built to withstand Mother Nature’s forces better than any of us could.

The solar industry acknowledges degradation, and that’s why solar panel manufacturers account for it in their warranties. The guarantee is that panels will produce electricity at least at 80 percent of their original capacity at the end of the 25-year warranty period. That means your panels will lose an average of less than 1 percent per year while they’re working for you. In a perfect world, there would be no degradation, but real-world factors are already built into this equation. And yet, many panels are expected to last beyond that 25-year time frame, a testament to their durability.
