Dust, pollen, and bird droppings can reduce solar panel output by up to 20%. Regular cleaning restores efficiency without damaging the panels.
When to Clean Your Panels
- After a dust storm (common in the Thar region).
- Following the monsoon season when grime collects.
- Every 6‑12 months for most urban locations.
Safety First
Never work on the roof alone. Use a harness or ladder with a stable base. If the roof is steep or inaccessible, book Solarium360’s professional cleaning service.
Required Tools
- Soft, non‑abrasive brush or sponge.
- Bucket of distilled water (tap water may leave mineral spots).
- Garden hose with low pressure (avoid high‑pressure jets).
- Micro‑fiber cloths for drying.
Step‑by‑Step Cleaning Process
- Cool Down – Clean panels when they are cool to the touch (early morning or late evening).
- Rinse Lightly – Spray water gently to remove loose dust.
- Scrub Gently – Use the soft brush with distilled water; avoid circular motions that can create micro‑scratches.
- Rinse Again – Flush away any remaining soap or debris.
- Dry – Pat dry with a micro‑fiber cloth to prevent water spots.
- Inspect – Look for cracked glass or loose connections.
Common Mistakes to Avoid
- Using abrasive pads or steel wool.
- Cleaning under direct sunlight – can cause sudden temperature shock.
