How do I clean solar panels in Nairobi?

Solar panels in Nairobi accumulate dust, red soil, bird droppings, and pollen that reduce energy output by up to 25%. Regular cleaning restores maximum efficiency.

How Often to Clean Solar Panels in Nairobi

• Dry season (January–February, July–August) – Monthly cleaning recommended; dust accumulates rapidly during dry, windy periods
• Rainy season – Rainfall washes panels naturally; inspect every 6–8 weeks and clean only if bird droppings or significant soil spots are visible

DIY Solar Panel Cleaning

1. Clean in the early morning or evening — never during peak sun hours when panels are hot; water on hot glass causes thermal shock
2. Switch off the solar system before cleaning
3. Rinse with plain water using a hose (low pressure)
4. Wipe with a soft squeegee or non-abrasive cloth — never abrasive pads that scratch the glass
5. For stubborn bird dropping: dampen with water, let it soften for a few minutes, then gently wipe
6. Rinse clean with water

What Not to Use

• Detergents or soaps — leave residue that attracts more dust
• High-pressure washers — can damage panel frames and seals
• Abrasive pads or brushes — scratch the anti-reflective coating
