Solar panels that are cleaned once and twice a year produce 3 5 and 5 1 more electricity respectively than those that are left uncleaned. Most manufacturers recommend cleaning at least twice a year.

This tends to result in a 3 to 5 increase in efficiency. In most cases you won t need to clean your solar panels often if at all. At the very least you should do an annual cleaning of your panels. There are some times it might make sense to clean your solar panels though.
