How often should you clean your solar panels?

Solar panels are low-maintenance, but “low” isn’t “none”. A little attention protects your investment.

Let the rain help

For most homes, regular rain keeps panels clean enough. A noticeable dip in production after a long dry, dusty stretch is the usual sign a clean would help.

When to get it checked

Every couple of years it’s wise to have the system checked — panels, connections and inverter — to catch any issue before it quietly costs you savings.
