Is It Worth Paying Someone to Clean Your Panels?

In dry Southern California conditions, cleaning can help, but whether paid cleaning is worth it depends on your math.

In local testing after long dry periods, panel cleaning improved production by roughly 10% in some cases.

If you can safely clean the system yourself, periodic washing may be worthwhile. If you need to hire someone, then the decision becomes a financial one: how long will the added generation take to repay the labor cost?

If your system already covers your needs, you may prefer to wait for the next rain. If the roof has years of buildup or residue that rain does not remove, a deeper cleaning may make more sense.
