By having clean solar panels, you’ll see optimum performance and save money. Cleaning your solar panels every 6 months will keep them running at their peak capacity and help prevent damage caused by dirt, mold, mildew, grime and other airborne pollutants that can block sunlight. If you don’t keep your solar panels clean, dirty solar panels can reduce power production by up to 40% or more, which means the amount of solar power you generate will also be reduced, and increase your electricity bills.
Some people try to do it themselves with a garden hose but this is really just a waste of water. Rain won’t clean the solar panels so you can be sure a hose won’t. Dirt and grime are usually baked onto the solar panels so they really need a good scrub with a soft brush, or proper pressure clean to lift them off.
This involves getting up on the roof and using professional pressure cleaning equipment to remove mold, grime and dirt (and scrubbing brushes if necessary). We use a safe and effective solar panel cleaning chemical that is environmentally friendly, non-toxic, biodegradable and streak free. We take the time to spray each panel individually so it can soak into the dirt particles before being lifted away by our high-pressure jets of water. It’s important to have an experienced company do the job because pressure cleaning is very powerful, and if you damage a panel it’s not going to be cheap to replace.
