How often should i clean solar panels.

Cleaning at regular intervals prevents buildup of residue and keeps your panels operating optimally at all times. After all anything that accumulates dirt on them for example dust or pollen will get washed off the next time it rains. You can include a solar panel cleaning as part of your spring cleaning routine. There are some times it might make sense to clean your solar panels though.

In most places there s more pollution in the winter which is why the spring is a good time to do an annual cleaning. In most cases you won t need to clean your solar panels often if at all. Most manufacturers recommend cleaning at least twice a year. 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.
