Solar panels save you money on energy bills and reduce your carbon footprint. If you want to make the most of this investment, you need to keep your solar panels clean and well-maintained. Solar panels are continuously exposed to the elements. Over time, dirt and dust can accumulate on the panel’s surface, blocking sunlight and minimising energy output.
Moreover, bird droppings, tree sap, and smog can also leave ugly and persistent stains on your solar panels. Yes, rain or a garden hose helps wash away the dirt, but it is not enough to remove those layers of grime. So, you need to hire an expert who has the experience, expertise, and equipment to handle such stubborn blemishes. Why look further when Billingsly Cleaning Services has it all?

The key to a perfectly clean, damage-free solar panel is the quality of water used for cleaning. We understand that tap water contains calcium, magnesium, and other minerals. When dried in the sun, these minerals leave behind stubborn white spots and streaks on your solar panel, the exact deposits you were trying to remove in the first place.
We use pure, mineral-free water for cleaning that acts like a magnet, pulling contaminants and dissolved solids from the panel surface. When the panels dry, the water evaporates completely, ensuring streak-free cleaning. For even better results, our cleaners use soft, synthetic brushes to safely scrub away dried bird droppings.
Moreover, we don’t use harsh chemicals, so there is no risk of damage to the photovoltaic cells. Get in touch with us today to book your solar panel cleaning service.
