Solar panel cleaning service involves the thorough, safe removal of dirt, dust, bird droppings, and other debris from the surface of solar panels to optimize their efficiency and energy output. The process typically includes inspecting the panels for damage, using specialized equipment such as soft brushes, squeegees, and eco-friendly cleaning solutions to gently clean the surface without causing scratches, and rinsing with purified water if necessary. Depending on the location and type of panels, the service may also involve checking and cleaning the mounting hardware and ensuring the panels are functioning correctly. Regular cleaning can significantly improve the panels’ performance and extend their lifespan.
Benefits of getting your solar panels cleaned?
We commit to high quality, customer satisfaction, and professionalism, often demonstrated by our reliable services, attention to detail, and friendly crew.
While heavy downpours can wash away loose dust, light rain often makes panels dirtier by redistributing existing particles and leaving a caked-on mineral residue when it evaporates. Rain also cannot remove sticky substances like bird droppings, tree sap, or heavy pollen.
As a general baseline, you should clean your solar panels 1 to 2 times per year, usually in the spring and fall. However, the ideal timeline depends heavily on your local environment:
On average, standard dust and soiling cause a modest 1% to 5% drop in efficiency. However, in highly polluted, dusty, or agricultural regions, severe buildup can block sunlight enough to cause a 10% to 25% drop in total energy production
It is highly recommended to avoid standard dish soaps, laundry detergents, and harsh chemicals. These products leave behind a thin soapy film or streaks that actually block sunlight and attract dirt faster. Instead, use plain water or a manufacturer-approved, specialized solar cleaning solution. If you must deal with oily residue or stubborn spots, a tiny drop of highly diluted, mild soap is acceptable if rinsed off immediately
Technically yes, but deionized or distilled water is best. Regular tap water—especially "hard water"—contains minerals like calcium. When tap water evaporates on hot glass, it leaves behind white mineral spots (scaling) that are very difficult to remove and reduce the panel's ability to absorb light
Yes! We use biodegradable window cleaning soap for sure. Biodegradable natural-based cleaning solution designed to break down safely into basic natural elements like water and carbon dioxide without leaving toxic residues
