Your commercial solar system was a significant investment. Now it’s time to protect that investment and maximize your returns.
Clean solar panels don’t just look better—they perform dramatically better. Studies consistently show that dirty panels lose 15-25% of their energy production capability. For a commercial operation, that translates to hundreds or thousands of dollars in lost savings every month.
The math is straightforward. When your panels operate at peak efficiency, you generate more power, reduce your energy costs, and see faster payback on your solar investment. Professional cleaning removes the dust, debris, and environmental buildup that blocks sunlight from reaching your solar cells.
All Seasons Window Cleaning Inc. has been providing commercial solar cleaning services across California for more than 10 years. We understand the unique challenges that Garnet’s climate presents for solar panel maintenance.
Southern California’s dry conditions, seasonal dust storms, and wildfire ash create the perfect environment for panel soiling. We’ve seen how quickly debris can accumulate and impact energy production in this region. That’s why we’ve developed specialized cleaning processes that work specifically for the environmental conditions businesses face here.
We’re fully licensed, bonded, and insured, giving you complete peace of mind when we service your commercial property. Our team uses professional-grade equipment and proven techniques that protect your panels while delivering exceptional results.
Our commercial solar cleaning process is designed for maximum effectiveness with zero risk to your equipment or property.
First, we conduct a complete assessment of your solar array. This includes identifying any areas of heavy soiling, checking for potential issues, and planning the safest approach for your specific installation. We never start cleaning without understanding exactly what we’re working with.
Next, we use deionized water and specialized soft brushes designed specifically for solar panels. This isn’t the same equipment used for windows or general cleaning. Deionized water leaves no mineral deposits or streaks, while our brushes remove stubborn debris without scratching the panel surface.
Finally, we perform a thorough rinse and inspection to ensure every panel is spotless. We document the work and can provide before-and-after photos showing the improvement in panel clarity. The entire process is completed safely and efficiently, often without disrupting your business operations.

Our commercial solar cleaning service includes everything needed to restore your panels to peak performance.
Every cleaning includes a visual inspection of your entire solar array. We look for signs of damage, loose connections, or other issues that could affect performance. While we’re not solar installers, we can identify problems early and recommend when you should contact your solar contractor.
We use only deionized water in our cleaning process. This specialized water has all mineral particles removed, making it a “dirt magnet” that pulls contaminants away from your panels. Unlike tap water, deionized water won’t leave behind calcium deposits or mineral stains that can actually make panels dirtier over time.
For Garnet businesses, we recommend cleaning every 3-6 months depending on your location and environmental factors. Properties near construction sites, busy roads, or agricultural areas typically need more frequent service. We can work with you to develop a maintenance schedule that keeps your system operating efficiently year-round.
Most commercial solar installations in the Garnet area should be cleaned every 3-6 months for optimal performance. However, the exact frequency depends on your specific location and environmental conditions.
If your business is near construction zones, agricultural operations, or major roadways, you may need cleaning every 3 months due to faster dust and debris accumulation. Properties in more protected areas can often go 6 months between cleanings. During wildfire season, additional cleanings may be necessary to remove ash and soot buildup.
We recommend monitoring your energy production data between cleanings. If you notice a drop in output of more than 10%, it’s time for service regardless of your regular schedule.
Yes, professional solar panel cleaning typically increases energy production by 15-25% immediately after service. Many of our commercial clients see even higher improvements, especially if panels haven’t been cleaned in over a year.
The improvement depends on how much soiling has accumulated on your panels. In Southern California’s dusty environment, even a thin layer of dirt can significantly reduce light transmission to your solar cells. Studies have shown that dirty panels can lose more than 25% of their energy output in some cases.
The energy production increase translates directly to cost savings on your electricity bills. For most commercial installations, the improved performance pays for the cleaning service many times over within just a few months.
Yes, professional solar panel cleaning can be performed safely while your system continues to operate. We don’t require you to shut down your solar array during the cleaning process.
Our technicians are trained in electrical safety procedures and use non-conductive equipment specifically designed for working around solar installations. We avoid contact with electrical components and focus solely on cleaning the glass surfaces of the panels.
However, we do recommend scheduling cleaning during lower production hours when possible, such as early morning or late afternoon. This timing is also better for the cleaning process itself, as cooler panel temperatures prevent rapid water evaporation that can leave spots.
Rain alone is not sufficient to keep commercial solar panels clean, especially in Southern California’s climate. While rain may wash away some loose dust, it often leaves panels dirtier than before.
Rainwater contains airborne pollutants, dust particles, and minerals that it picks up as it falls. When this contaminated water evaporates from your panels, it leaves behind deposits that can actually cement to the glass surface. This creates a film that’s much harder to remove than the original dust.
Professional cleaning uses deionized water that contains no minerals or contaminants. Combined with proper techniques and specialized equipment, this removes all buildup without leaving any residue. The result is panels that stay cleaner longer and perform at their maximum efficiency.
Commercial solar panel cleaning costs vary based on the size of your installation, accessibility, and frequency of service. We provide customized quotes for every project because each commercial system has unique requirements.
Factors that affect pricing include the number of panels, roof height and complexity, current condition of the panels, and whether you choose one-time service or a regular maintenance plan. We offer discounts for recurring service contracts because regular cleaning is more efficient and better for your panels.
Most commercial clients find that the immediate increase in energy production more than pays for the cleaning service. When panels are producing 15-25% more electricity, the improved performance typically covers the cleaning cost within 2-3 months while providing ongoing savings throughout the year.
Yes, excessive soiling can potentially damage your solar panels and may affect warranty coverage. Many solar panel manufacturers require regular maintenance as part of their warranty terms.
Heavy buildup of dirt, debris, and bird droppings can create hot spots on panels where some cells are blocked while others continue producing electricity. This uneven heating can cause permanent damage to the solar cells and reduce the lifespan of your panels.
Additionally, some manufacturers specifically require documentation of regular professional cleaning to maintain warranty coverage. We provide detailed service records that can be used to support warranty claims if issues arise. Regular professional cleaning protects both your investment and your warranty coverage.
