Keep Dirt, Debris & Buildup Off Your Solar Panels
Pro Care, Inc. has been serving residential and commercial customers across the greater Seattle and Bellevue area since 2002, and solar panel cleaning is one of the specialized services our trained technicians handle with the same attention to detail we bring to every job. If you have made the investment in solar energy, keeping those panels clean is one of the most important things you can do to protect that investment and ensure your system performs the way it was designed to.
Many homeowners assume rain is enough to keep their panels clean, but it is not. Dust, pollen, algae, bird droppings, and the general grime that accumulates on any outdoor surface will reduce your panels’ ability to absorb sunlight over time. Studies suggest that dirty panels can lose up to 22% efficiency on residential systems and up to 60% on commercial installations. Beyond performance, neglecting regular cleaning can void some manufacturer warranties. Pro Care uses the proper tools and cleaning solutions to remove buildup safely without scratching panel glass or damaging frames and seals.

Solar Panel Cleaning FAQs
Why do solar panels need to be cleaned if it rains frequently in the Pacific Northwest?
Rain can rinse off loose dust but it is not effective at removing pollen, algae, bird droppings, or the mineral deposits left behind as water evaporates. These contaminants build up on the panel surface over time and reduce the amount of sunlight that reaches the cells. Regular professional cleaning removes what rain cannot.
How much efficiency can dirty solar panels lose?
Studies indicate that soiled panels can lose up to 22% of their energy output on residential systems and up to 60% on commercial installations. In a region that already has fewer peak sunlight hours than much of the country, keeping panels clean is especially important to maximize your system’s output.
How often should I have my solar panels cleaned?
Pro Care recommends cleaning solar panels two to three times per year to maintain peak efficiency. Spring is an important time to clear pollen and winter grime, and additional cleanings throughout the year help offset the ongoing buildup of dust and organic material. Our team can keep an eye out for any maintenance concerns while on site.
Can cleaning damage my solar panels?
Solar panels can be scratched or degraded by improper cleaning methods, including abrasive brushes or harsh chemical cleaners. Pro Care uses panel-safe tools and appropriate cleaning solutions to ensure your glass and frames are not harmed during the process.
Will cleaning my panels void the manufacturer’s warranty?
Failing to maintain your panels is actually more likely to affect your warranty than having them professionally cleaned. Many manufacturers recommend regular cleaning as part of proper maintenance. Using a qualified professional who uses the correct methods helps ensure you remain in compliance with warranty requirements.
Do you clean both rooftop and ground-mounted solar panels?
Yes. Pro Care handles both rooftop residential systems and ground-mounted commercial and residential arrays. Our technicians are equipped to work safely at height and in a variety of site configurations.
Can you clean panels if it is raining?
Light rain is generally not a barrier to cleaning, and our team is always prepared to work in typical Pacific Northwest weather conditions. If conditions are severe enough to impact safety or results, we will let you know and reschedule promptly.
How does pricing work for solar panel cleaning?
We price per job rather than per hour. Factors such as the number of panels, their location and accessibility, and the level of buildup present are all taken into account. The quote you receive is the price you are billed, with no surprises.
