How many years does the average solar panel last?

    The average solar panel has a life span of about 20-25 years.  For every year that it is used, the value and wattage output decreases.  If you want your solar panel to remain as efficient as it is when it is new, then it is probably a good idea to have it replaced before the 20 or 25 year expiration.
