Are Your Solar Panels Still Paying for Themselves?

Every year, solar panels endure various weather conditions and accumulate dust, grime, bird droppings, pollen, and more. These factors can significantly reduce your panels’ production rates. Just like everything else in life, regular maintenance is essential to keep your solar panels in optimal condition, ensuring they save you money throughout the year—which is precisely why we install them in the first place.

Solar panels, much like any smooth, flat surface, collect debris over time. This process, known as soiling, is problematic because it decreases solar panel efficiency, leading to reduced energy production and profitability. Studies have shown that contaminants can reduce solar panel efficiency by up to 76% in some regions.

There is a common myth that solar panels are “self-cleaning” when it rains. However, consider this: is your car’s windshield “self-cleaning” when it rains? The top layer of solar panels is made of hard glass, and when mixed with pollen, dust, and other debris that accumulates over six months or more, this buildup needs to be physically scrubbed off with a brush, just like your vehicle.

At The Wash, we use specialized pure-water, non-abrasive brushes and environmentally friendly systems to remove buildup and leave your solar panels free of photon-blocking mineral deposits (water spots).
