Step-by-Step: How to Clean Solar Panels

1️⃣ Turn off your solar system.
Safety comes first. Switch off the inverter before starting.
2️⃣ Use soft cleaning tools.
Use a microfiber cloth, sponge, or soft brush. Avoid hard bristles that can scratch glass.
3️⃣ Rinse with clean water.
Use a hose or bucket of plain water. Don’t use high-pressure jets.
4️⃣ Gently wipe the surface.
Move in circular motions to remove dust, bird droppings, and pollen.
5️⃣ Avoid soap or chemicals.
These can leave stains and reduce transparency. Use mild detergent only if the panels are very dirty.
6️⃣ Let them air dry.
Do not use towels; water spots will dry naturally.
Additionally, try to clean in the morning or evening when panels are cool to avoid cracks or burns.
