When your commercial solar panels are clean, everything changes. You’ll see immediate improvements in energy output—sometimes up to 35% more production from panels that looked “clean enough” from the ground.
That translates to real money back in your pocket. Lower energy bills. Faster return on your solar investment. Better cash flow for your business.
Clean panels don’t just produce more energy—they last longer too. Professional cleaning prevents the buildup of corrosive materials that can permanently damage your expensive solar equipment.
All Seasons Window Cleaning Inc. has been serving Southern California’s commercial solar cleaning needs with the specialized equipment and expertise your investment deserves. We’re not just another cleaning company—we understand solar technology.
Corona’s agricultural and industrial environment creates unique challenges for solar panel maintenance. Dust from farming operations, industrial emissions, and the region’s dry climate all contribute to faster panel soiling than other areas.
That’s why businesses across Corona trust us with their solar cleaning. We use professional-grade deionized water systems and specialized brushes designed specifically for solar panels—never harsh chemicals that could void your warranty.
Our commercial solar cleaning process starts with a comprehensive site assessment. We evaluate your panel configuration, access requirements, and any specific challenges your installation presents.
Next, we use our specialized deionized water system to remove all dirt, dust, bird droppings, and other contaminants without leaving mineral deposits. Our rotating brush technology is gentle enough to protect your panels while powerful enough to remove stubborn soiling.
Every cleaning includes a visual inspection of your entire solar array. We check for potential issues like loose connections, damaged panels, or pest intrusion that could affect performance. You’ll receive a detailed report of our findings so you can address any concerns before they become expensive problems.

Our commercial solar cleaning service covers everything your panels need to perform at peak efficiency. We handle rooftop installations, ground-mount arrays, solar carports, and agricultural solar systems throughout Corona and Riverside County.
Corona’s location in Southern California’s agricultural belt means your panels face unique challenges. Dust from farming operations, pollen during growing seasons, and industrial emissions all contribute to faster soiling rates than typical urban areas.
We understand these local conditions and adjust our cleaning schedules accordingly. Agricultural solar installations often need more frequent cleaning—sometimes every 3-4 months during peak growing seasons—while commercial rooftop systems might need service twice yearly.
Our flexible scheduling includes overnight cleaning for retail locations and businesses where daytime operations can’t be interrupted. We’re fully licensed and insured, and we can add your company as an additional insured on our policy for complete protection.
Most commercial solar installations in Corona benefit from cleaning every 4-6 months, but your specific needs depend on your location and environment. Agricultural properties and businesses near farming operations typically need more frequent cleaning—every 3-4 months—due to higher dust and pollen exposure.
Industrial areas with more air pollution may also require quarterly cleaning. We’ll assess your specific situation during our initial visit and recommend an optimal cleaning schedule based on your panel soiling rate and energy production data.
Regular monitoring of your energy output is the best way to determine if your panels need cleaning. If you notice a drop in production that can’t be explained by weather or seasonal changes, it’s time for professional cleaning.
Regular tap water contains minerals like calcium and magnesium that leave spots and buildup on your solar panels, actually reducing their efficiency over time. These mineral deposits can be nearly impossible to remove once they set in, potentially requiring expensive panel replacement.
Deionized water has had all minerals removed through a specialized filtration process. It dries completely clear without leaving any residue, ensuring your panels maintain maximum light absorption. This is especially important in Corona where hard water is common.
Using deionized water also protects your panel warranty. Many manufacturers specify that only pure water should be used for cleaning, and using regular water or cleaning chemicals could void your warranty coverage.
Yes, studies by major universities including the University of Houston have documented energy losses of 20-35% from soiled solar panels. In Corona’s agricultural environment, we regularly see panels that appear “clean enough” from ground level but are actually operating at significantly reduced capacity.
The impact varies by location and soil type. Agricultural areas with fine dust, pollen, and organic matter tend to see faster efficiency loss than urban installations. Bird droppings, tree sap, and industrial emissions can create localized “hot spots” that block entire sections of panels.
We’ve had customers see immediate production increases of 1-2 kWh per panel after professional cleaning. For a typical commercial installation, that translates to hundreds or thousands of dollars in recovered energy production annually.
We strongly advise against having your staff clean rooftop solar panels. Beyond the obvious fall risks, improper cleaning techniques can cause expensive damage to your panels and void your warranty coverage.
Solar panels require specific cleaning methods, tools, and water purity to avoid damage. Using pressure washers, abrasive materials, or regular cleaning chemicals can crack panels, damage anti-reflective coatings, or create micro-scratches that permanently reduce efficiency.
Our team is OSHA-certified for rooftop work and carries comprehensive insurance coverage. We use professional safety equipment and have extensive experience working around electrical systems. The cost of professional cleaning is minimal compared to the potential liability and equipment damage risks of DIY cleaning.
Yes, we have the equipment and experience to handle large-scale commercial solar installations including solar farms, agricultural arrays, and utility-scale projects throughout Corona and Riverside County. Our specialized equipment can clean thousands of panels efficiently while maintaining the highest safety standards.
Large installations require different approaches than rooftop systems. We use professional rotating brush systems and can deploy multiple crews simultaneously to minimize downtime. For ground-mount systems, we can often complete cleaning without interrupting your energy production.
We’re experienced with the unique requirements of utility-scale projects including safety protocols, environmental compliance, and coordination with grid operators. Our team can work around your operational schedule and provide detailed documentation for your maintenance records.
We carry comprehensive general liability and professional indemnity insurance specifically covering solar panel cleaning operations. Our insurance can cover the full replacement cost of damaged panels, lost energy production, and any related expenses.
However, panel damage is extremely rare when proper techniques and equipment are used. We use only soft-bristle brushes designed specifically for solar panels, maintain proper water pressure, and never use abrasive materials or harsh chemicals that could cause damage.
Before starting any project, we document the existing condition of your panels with photos and inspect for any pre-existing damage. Our technicians are trained to identify potential issues and will stop work immediately if they encounter any problems. We can also add your company as an additional insured on our policy for extra protection.
