Dirty solar panels lose up to 25% of their efficiency. Davis Brothers restores your panels to peak performance with safe, professional cleaning.
You invested thousands of dollars in solar panels to save money on energy and reduce your environmental footprint. But if those panels are covered in dust, pollen, bird droppings, or grime, they are not producing the energy you are paying for.
Studies show that dirty solar panels can lose 15% to 25% of their energy output. In Sacramento's dusty Central Valley climate, that loss adds up fast — especially during peak summer months when your panels should be working hardest.
Davis Brothers provides professional solar panel cleaning for residential systems throughout Sacramento and Woodland. We use purified water and soft-bristle tools to safely remove buildup without scratching or damaging your panels. No harsh chemicals. No high-pressure sprayers. Just clean panels producing the energy they were designed to deliver.
We inspect your panels from ground and roof level, noting the type of buildup, panel condition, and any potential issues.
We use proper safety equipment and follow all rooftop safety protocols. Your panels and your roof are treated with care.
We use purified, deionized water with soft-bristle brushes to gently remove dirt, dust, pollen, bird droppings, and deposits. Zero residue.
After cleaning, we visually inspect each panel for cracks, hot spots, or wiring issues and notify you of anything that needs attention.
We recommend checking your system's energy output before and after cleaning so you can see the difference for yourself.
Most homeowners see a significant improvement in energy production after a professional cleaning.
Cleaner panels produce more electricity, maximizing your return on your solar investment.
Most manufacturers recommend regular cleaning. Our methods are safe for all major panel brands.
Our post-cleaning inspection catches cracks, hot spots, and wiring problems before they become expensive repairs.
For most Sacramento homes, we recommend solar panel cleaning one to two times per year. The best times are late spring (after pollen season) and early fall (before the rainy season).
Homes near agricultural areas, construction sites, or with heavy bird activity may benefit from more frequent cleaning.
No. In fact, most solar panel manufacturers recommend regular cleaning as part of routine maintenance. We use manufacturer-approved methods that are safe for all major panel brands.
We do not recommend it. Tap water contains minerals that leave spots and residue on your panels, reducing efficiency. High-pressure water can also damage panel seals. Our purified water system avoids both problems.
Most residential systems in Sacramento cost between $150 and $350 to clean, depending on the number of panels and roof accessibility. We provide free estimates.
Results vary based on how dirty your panels are, but most homeowners see a 10% to 25% improvement in energy output after a professional cleaning.
