How long will my system last?

A solar photovoltaic (PV) system that is designed, installed, and maintained properly will operate for more than 25 years. The basic PV module has no moving parts and can last more than 40 years. The best way to ensure and extend the life and effectiveness of your solar system is by having it installed by NABCEP trained professionals. Experience has shown that most problems occur because of poor or sloppy system design and installation.
