How much maintenance does solar need?
Reviewed by SolvSolar · Last reviewed:
Solar needs very little maintenance — mainly panel cleaning and an annual electrical inspection. Clean every 1–3 months in dusty regions and less often in rainy climates; skipping it can cost 3–8% of annual yield to soiling. Budget 0.5–1% of system value per year for O&M, and rely on remote monitoring alerts to catch faults early.
