How Long Do Solar Panels Last?

Solar panels last 30-40 years, with little to no maintenance required. Typically, solar panels lose about 0.5% of efficiency every year due to depreciation. With this model, after forty years of energy savings, your solar panel system will still be operating at 80% efficiency. We must keep in mind, however, that this model serves as an estimate; it is just an average over the long run. Depending on the area you live in and how thoroughly and frequently you clean your solar panels (refer to ­­­­­­”How Important is it to Wash My Solar Panels?”), your solar panel system may last even longer than the average.

Most solar panels and many inverters include a 25-year manufacturer warranty, so you can rest assured that any problems that arise from normal use, although rare, will be fixed free of charge. Nonetheless, most solar panel users will never have to use their warranty and will find that their panels will operate near maximum efficiency even 15-20 years after their warranty has ended.

In addition to the manufacturer warranties, Aikyum Solar offers further protection such as a 10-year roof repair and labor warranty and a 25-year production guarantee. Aikyum Solar also provides a free monitoring system so that we can identify and quickly fix any problems that may occur throughout the life of the system.
