Premium panels degrade more slowly, often at a rate as low as 0. Put quality panels on your roof and you can. . Solar panel degradation comprises a series of mechanisms through which a PV module degrades and reduces its efficiency year after year. How fast they lose their power, how long warranties last and what to do to prolong the lifespan of your solar system — here in this article. There is little that can happen to a solar panel. 8% per year, sometimes even less. Most continue producing clean energy well beyond their 25–30‑year warranties.
