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? Conventional silicon solar panels that are designed for a rooftop or utility installation can be expected to last 25 years. Some of the top brands come with 25 year product warranties, in which case you can consider 25 years to be the minimum lifespan.
