Get More Power from Your Solar Panels
Davis Brothers cleans residential solar panels in Sacramento and Woodland with purified water and soft-bristle tools. Request an estimate based on panel count and roof access.
Why Clean Your Solar Panels?
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.
Dirt and debris can reduce the sunlight reaching solar cells. The effect varies with the system, local conditions, and the amount of buildup. 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.
For independent information about solar maintenance and performance, see the U.S. Department of Energy’s homeowner guide to solar and your panel manufacturer’s care instructions.
Our Solar Panel Cleaning Process
Assessment
We inspect your panels from ground and roof level, noting the type of buildup, panel condition, and any potential issues.
Safe Access
We use proper safety equipment and follow all rooftop safety protocols. Your panels and your roof are treated with care.
Purified Water Cleaning
We use purified, deionized water with soft-bristle brushes to gently remove dirt, dust, pollen, bird droppings, and deposits. Zero residue.
Inspection
After cleaning, we look for visible damage or debris and flag concerns for your solar installer. Electrical testing and hot-spot diagnosis are outside the cleaning service.
Performance Check
We recommend checking your system's energy output before and after cleaning so you can see the difference for yourself.
Benefits of Clean Solar Panels
Remove Light-Blocking Buildup
Cleaning removes surface dirt. Any change in energy output depends on existing buildup, weather, and system condition.
Save Money on Energy Bills
Cleaner panels produce more electricity, maximizing your return on your solar investment.
Protect Your Warranty
Check your panel manufacturer’s cleaning and warranty instructions before scheduling service.
Spot Issues Early
We can flag visible concerns for you to discuss with your solar installer. A cleaning visit is not an electrical inspection or a hot-spot diagnosis.
How Often Should You Clean?
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.
Solar Panel Cleaning FAQ
Will cleaning void my solar panel warranty?
Warranty conditions vary by manufacturer. Share your panel model and care instructions before the visit so the cleaning method can be checked against them. Cleaning does not replace inspection or repair by your solar installer.
Can I just spray my panels with a hose?
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.
How much does solar panel cleaning cost?
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.
How much energy will I gain after cleaning?
There is no fixed percentage gain. Results depend on dirt levels, weather, panel orientation, and system condition. Compare monitoring data under similar conditions, and ask your installer about persistent production problems.
