Maximize Your Energy Output with Professional Cleaning
Why Dirty Solar Panels Cost You Money
Over time, solar panels accumulate layers of dust, dirt, pollen, bird droppings, and other environmental debris. This buildup creates a film that blocks sunlight from reaching the photovoltaic cells, significantly reducing their ability to convert sunlight into electricity. This loss in efficiency means you’re not getting the full return on your investment, leading to higher-than-necessary energy bills and diminished savings.
Regular, professional cleaning is the key to unlocking your system’s full potential. By removing the grime and restoring the panels’ transparency, we ensure they can absorb the maximum amount of sunlight. This translates directly to increased energy production, helping you lower your carbon footprint and save more money on your utility costs month after month.
Safe and Effective Techniques for Optimal Results
Our cleaning process is meticulous and designed for maximum effectiveness without compromising the integrity of your panels. We begin with a careful inspection to assess the level of soiling and identify any potential issues. We then use a pure-water cleaning system, which involves filtered, deionized water that leaves no mineral deposits or spots behind, ensuring a streak-free finish that repels dirt longer.
What truly sets us apart is our commitment to quality equipment. At California Glass and Solar, we design and manufacture all of our own brushes in-house at our shop. This unique capability allows us to create soft-bristled, non-abrasive brushes specifically engineered for the delicate surfaces of solar panels. Our custom tools guarantee a deep clean that safely removes stubborn grime without scratching or damaging your valuable asset.
Protect Your Panels and Yourself
Attempting to clean solar panels yourself can be hazardous. Most residential systems are located on rooftops, and working at heights without professional safety gear and training poses a significant risk of falls and serious injury. A slippery roof surface, especially when wet, is an accident waiting to happen for the unprepared homeowner.
Beyond personal safety, there is a substantial risk of damaging your solar panels. Using standard tap water can leave behind mineral buildup that etches the glass over time. The wrong cleaning solutions or abrasive tools like hard-bristled brushes can cause permanent scratches, which create shadows on the cells and reduce efficiency. This type of damage is often not covered and can even void your manufacturer’s warranty.
Hiring the professionals at California Glass and Solar eliminates all these risks. Our technicians are fully trained in safety protocols and equipped with the proper gear to work securely on any roof. We use only panel-safe, custom-made equipment and purified water, ensuring your system is cleaned correctly while preserving its warranty and performance for years to come.

Linda Plummer2021-07-11Trustindex verifies that the original source of the review is Google. We are thrilled with the window cleaning provided by California Glass & Solar. Melanie was able to do our cleaning just two days after she had provided the quote. She was extremely neat and thorough. The views are now so clear we are constantly saying to each other that it's as if there is no glass in the windows. Sandra Black2021-07-10Trustindex verifies that the original source of the review is Google. I contacted Melanie at California Glass and Solar via phone after seeing her website. We communicated via text regarding property and time to do a site visit. Price was reasonable and work was performed during the initial site visit. Within an hour all panels were clean and shiny. Melanie and her helper were very friendly, efficient and easy to deal with. They did a great job cleaning some very dirty solar panels! I would highly recommend their company. In the photo is the Before (right) and After (left) picture. What a difference! David Finger2021-07-09Trustindex verifies that the original source of the review is Google. I used California Glass and Solar to clean the solar panels on my 2 story home and will definitely be using them again. They did a great job and showed me before and after pictures, even cleaning off some paint the painters had inadvertently put on the panels. Even cleaned the sky light while they were up there. Super nice, great job, very professional. Kelly Ann2020-07-29Trustindex verifies that the original source of the review is Google. Amazing !! Melanie runs a great company, her service techs are prompt, polite and do an amazing job! My windows/solar panels have never been cleaner! Definitely will be having them clean them from now on. Great job! Andrea McCrossen2020-07-29Trustindex verifies that the original source of the review is Google. Extremely professional!! Steve Levy2020-07-29Trustindex verifies that the original source of the review is Google. I have been a customer of California Glass and Solar for over 3 years. They have not only cared for our Array (2 story so two levels) from a soling and cleaning perspective but are always on the look out for anything they see "Micro Cracks" as an example that a homeowner would not see from the ground. They go the extra mile and are well worth the money to keep your PV investment running as designed.
