Solar panels are extremely durable and with no moving parts, they will generally require little to no maintenance. As of now, the average lifespan of solar panels for housing is about 25-30 years however, some systems can last for even 50! We even go one step further for our customers. We are one of only a handful of contractors that offer SOLAR INSURE! It is a 3rd party insurance-backed warranty plan included in your system when you install with Castaways Energy! This is an additional 30-year warranty coverage for panels, inverters, optimizers, and roof penetrations. Solar Insure will pay for any labor needed to service your system, and has ownership transfers at NO FEE! When you have your system installed with Castaways Energy, you are not only saving money, you are saving for years to come with a peace of mind like nowhere else!
