You installed solar panels to save money and reduce your environmental impact. But when dust, bird droppings, and Fontana’s unique environmental challenges build up on your panels, you’re losing the energy production you paid for.
Clean panels can increase your energy output by up to 20%. That’s not just better performance—that’s real money back in your pocket every month. When your panels operate at peak efficiency, you maximize your return on investment and extend the life of your system.
Professional cleaning also means professional inspection. We catch small issues before they become expensive problems, protecting your warranty and ensuring your system runs smoothly for decades.
All Seasons Window Cleaning has been serving Fontana properties for years, and we understand exactly what your solar panels face in our local environment. The dust from nearby construction, seasonal winds, and the Inland Empire’s unique climate conditions all affect how your panels perform.
We’re not just another cleaning company that added solar to our services. We’ve invested in manufacturer-approved equipment, specialized training, and the right techniques to clean your panels safely without voiding your warranty.
Our team knows Fontana. We know which neighborhoods deal with more dust, where bird problems are common, and how local weather patterns affect panel maintenance needs. That local knowledge translates into better care for your investment.
We start with a complete visual inspection of your solar array. Our technicians check for any damage, loose connections, or potential issues before we begin cleaning. This isn’t just about making your panels look good—it’s about ensuring they’re operating safely and efficiently.
Our cleaning process uses only pure deionized water and manufacturer-approved tools. No harsh chemicals that could damage your panels or void your warranty. We use soft-bristle brushes and specialized equipment designed specifically for solar panel surfaces.
After cleaning, we perform a final inspection and can provide thermal imaging to identify any hot spots or underperforming cells. You’ll see the difference immediately—cleaner panels that capture more sunlight and produce more energy for your home or business.

Fontana’s environment presents unique challenges for solar panel maintenance. Our desert climate means more dust accumulation, and our location in the Inland Empire exposes panels to pollutants from nearby highways and industrial areas. Regular professional cleaning isn’t just recommended—it’s essential for protecting your investment and maximizing your energy production.
Most Fontana homeowners benefit from cleaning their solar panels every 6 months, though some properties may need quarterly service depending on their specific location and environmental factors. Properties near construction sites, busy roads, or areas with heavy bird activity typically require more frequent cleaning.
The frequency also depends on your panel’s tilt angle. Flatter installations tend to accumulate more debris because gravity doesn’t help wash away dust and dirt as effectively. We’ll assess your specific situation during our first visit and recommend the optimal cleaning schedule for your system.
Yes, professional cleaning can increase your panel efficiency by 15-20% on average, with some heavily soiled systems seeing improvements of up to 50%. Even a thin layer of dust can block significant amounts of sunlight from reaching your photovoltaic cells.
Research shows that panels lose approximately 0.05% of their efficiency per day due to dust accumulation. In Fontana’s environment, where dust and pollution are common, this adds up quickly. A system that hasn’t been cleaned in six months could easily be operating at 80-85% of its potential capacity.
We strongly recommend professional cleaning for several important reasons. First, safety—working on rooftops is dangerous, and solar panels can become extremely slippery when wet. Second, improper cleaning techniques or tools can scratch your panels or void your manufacturer’s warranty.
Professional cleaners use specialized equipment, pure deionized water, and manufacturer-approved methods that protect your investment. We’re also trained to identify potential issues during cleaning, like loose connections, cracked panels, or inverter problems that could affect your system’s performance.
We use only pure deionized water and soft-bristle brushes specifically designed for solar panel surfaces. Our water filtration system removes all minerals that could leave spots or residue on your panels. We never use harsh chemicals, abrasive materials, or high-pressure washing that could damage the panel surface or seals.
Our cleaning process follows manufacturer guidelines to ensure your warranty remains valid. We also avoid cleaning during the hottest parts of the day to prevent thermal shock, and our technicians are trained in proper techniques that clean effectively without applying excessive pressure to the panel surface.
The cost depends on your system size, roof accessibility, and how frequently you schedule cleaning. Most residential systems in Fontana range from $150-$300 per cleaning, while the increased energy production typically pays for the service within a few months.
When you consider that dirty panels can lose 20-30% of their efficiency, professional cleaning is an investment that pays for itself. A typical 5kW system producing 20% less energy due to soiling could cost you $200-400 per year in lost electricity production, making professional cleaning a smart financial decision.
Yes, we guarantee our workmanship and stand behind the quality of our cleaning service. If you’re not satisfied with the results, we’ll return to address any issues at no additional charge. We’re also fully licensed, bonded, and insured for your protection.
