How long do solar panels last?
Installing solar panels on your house is a pretty big investment - one that you’d like to last as long as possible. So how long should you expect your home solar array to last? Solar panels last a really long time. You can expect at least a 25 year lifespan. Premature failures do happen, but they are often covered by the manufacturer’s warranty. Solar panels have been known to last much longer - as long as four decades - but there is little data because mass commercialization of photovoltaic panels really only started happening in the 1970s.
