HOW OFTEN SHOULD SOLAR PANELS ACTUALLY BE CLEANED?

Dust, pollen, bird activity, and general airborne grime settle on panel surfaces over time, and the resulting soiling loss can meaningfully reduce a system's energy output — often more than owners assume, especially in dry, dusty regions.

For most residential and commercial installations, a cleaning cycle every three to six months is a reasonable baseline, with large ground-mounted or industrial arrays sometimes needing more frequent attention depending on location and local conditions.

Cleaning cadence should really be driven by monitored output data rather than a fixed calendar — which is exactly why we pair cleaning services with ongoing performance monitoring, so a drop in output triggers a visit rather than waiting on a schedule.
