1. Power down per your inverter manual and open DC disconnects if present. Work in the cool morning.
2. Inspect from the ground. Mark droppings, pollen bands, or shade issues to target.
3. Soft tools only. Use a microfiber pad or soft brush on a telescoping pole; skip pressure washers and harsh chemicals.
4. Rinse and wipe. Distilled water helps avoid spotting; if needed, mild pH‑neutral soap and thorough rinse.
5. Restore power and verify output. Compare power vs. yesterday at similar sun angle; small gains are normal after light soiling.
6. Set cadence. Dusty/pollen/coastal: quarterly; elsewhere: semiannual, with storm follow‑ups.
