Why Solar Panels Can Last So Long

Solar is a long-term investment, which means your panels need to last a long time. Luckily, the vast majority of solar panel systems can last for decades. Today, there are still functioning systems that were installed back in the 1980s when solar energy was in its infancy. How is that even possible? We’ll explain it in this blog!

Degradation of Solar Panels Over Time

Solar panels aren’t immune to the effects of time. Solar panels slowly lose efficiency and effectiveness over time. However, this is only about 1% in performance per year. Remember that solar panels don’t cost anything after the initial installation. Even after 20 years, your solar panels will still be providing free energy for your home. That’s great news, especially for a system that requires no maintenance. You can trust in your solar panels going the distance and lasting for as long as you need them.

Why Does It Happen?

There are no moving parts in a solar panel system so you don’t have to worry about any mechanical breakdowns. Solar panels degrade slowly over time because of a process known as thermal cycling. The paneling slowly expands and cools over time, creating small stressors and cracks in the system.

Other weather effects like strong wind or hail can damage the system over time as well. There are still innovations in solar technology that may dampen the effects of thermal cycling, but even current systems retain the majority of their power production decades after installation.
