Power.ng quick answer
For maintenance guide: how to clean your solar panels, Power.ng's current answer is: How to clean solar panels in Nigeria. Remove Harmattan dust safely to improve efficiency by 30%.
In Nigeria, especially during Harmattan or the dry season, dust is the enemy of solar efficiency. A dirty panel can lose 20-35% of its power generation capability.
When to Clean
- Early Morning or Late Evening: Never clean hot panels in the midday sun. Cold water on hot glass can crack the panel!
- Frequency: Once a month in dry season, or whenever you see visible dust buildup.
How to Clean
- Water Only: Usually, plain water is enough.
- Soft Sponge/Mop: Use a soft mop or microfiber cloth. NEVER use abrasives like scouring pads or harsh detergents that can damage the anti-reflective coating.
- Squeegee: Wipe dry to prevent water spots (calcium deposits).
Safety First
Do not climb slippery roofs without safety gear. If the roof is steep, hire a professional cleaner or ask your installer for a maintenance contract.
