Your solar panels work harder when they’re clean. Dust, pollen, and bird droppings can slash your system’s efficiency by up to 25%, costing you hundreds in lost energy savings every year.
Professional cleaning restores that lost performance immediately. You’ll see the difference in your next electricity bill—lower costs, higher production, and the peace of mind that comes from protecting a major investment.
Clean panels don’t just perform better. They last longer, maintain their warranty coverage, and keep your home looking sharp from the street.
All Seasons Window Cleaning Inc. has been serving Hemet homeowners for over 10 years with professional solar panel cleaning and maintenance. We’re fully bonded and insured, treating every home with the care it deserves.
Hemet’s unique climate—with its dry conditions, seasonal winds, and proximity to agricultural areas—creates specific challenges for solar panel maintenance. We understand these local conditions and use proven techniques that work in our environment.
Our eco-friendly deionized water system leaves your panels streak-free without harsh chemicals that can void warranties or damage delicate surfaces.
We start with a complete inspection of your solar array, checking for damage, bird activity, and areas that need special attention. This helps us spot potential problems before they become expensive repairs.
Next comes the cleaning itself. We use deionized water and specialized brushes designed specifically for solar panels—no harsh chemicals or abrasive materials that could scratch or damage your investment.
Finally, we inspect our work and provide you with a clear assessment of your system’s condition. If we spot any issues with mounting hardware, wiring, or potential bird problems, we’ll let you know so you can address them before they impact your energy production.

Our solar panel cleaning service includes thorough removal of dust, pollen, ash, and bird droppings that accumulate on Hemet properties. We also clean the frames and check mounting hardware for signs of corrosion or wear.
Bird-proofing is available as an add-on service. Hemet’s location near agricultural areas and water sources makes it attractive to pigeons and other birds that can nest under panels, causing drainage problems and leaving acidic droppings that permanently damage glass surfaces.
We recommend cleaning every 6 months for most Hemet homes, though properties near farms or with heavy bird activity may benefit from more frequent service. Our deionized water system ensures a spot-free finish that helps panels stay cleaner longer between visits.
Dirty solar panels can reduce energy production by 15-25% in Hemet’s dusty environment, with some cases showing losses up to 40% when bird droppings are involved. This translates to hundreds of dollars in lost energy savings annually for the average residential system.
The problem is particularly acute in Hemet because our semi-arid climate means less natural cleaning from rainfall. Dust particles actually cement to panel surfaces overnight as temperatures drop and morning dew forms, making the buildup harder to remove over time.
Regular professional cleaning every 6 months typically restores full efficiency and prevents the kind of permanent staining that can occur when contaminants are left too long on panel surfaces.
Bird droppings are the most destructive type of solar panel contamination because they’re acidic and sticky. Unlike dust that might blow away, droppings adhere firmly to glass surfaces and can actually etch into the protective coating under Hemet’s intense sunlight.
The moisture content in droppings helps them spread across multiple cells when they hit your panels, blocking sunlight from larger areas. Research shows bird droppings can reduce individual panel output by up to 23.8%, and the damage gets worse the longer they remain on the surface.
Professional removal is essential because trying to scrape off hardened droppings yourself can scratch the glass and void your warranty. Our specialized cleaning process safely removes all traces without damaging your panels’ protective coatings.
Most Hemet homeowners benefit from professional solar panel cleaning every 6 months, though some properties may need more frequent service depending on their specific conditions. Homes near agricultural areas, with heavy bird activity, or in particularly dusty locations might need quarterly cleaning.
The key is monitoring your system’s performance through your inverter or monitoring app. If you notice a gradual decline in energy production that can’t be explained by weather or seasonal changes, it’s time for a cleaning regardless of your regular schedule.
We can help you determine the optimal cleaning frequency for your specific property based on your system’s performance data, local environmental factors, and your energy usage patterns.
Professional cleaning with proper techniques and materials will not void your solar panel warranty—in fact, most manufacturers require regular maintenance to keep warranties valid. However, using harsh chemicals, abrasive materials, or improper cleaning methods can void coverage.
We use only deionized water and soft brushes specifically designed for solar panels. This approach meets or exceeds all major manufacturer cleaning guidelines while ensuring your panels receive thorough cleaning without risk of damage.
Many manufacturers actually recommend against using soap or chemical cleaners, which is why our pure water system is the safest choice for protecting both your panels and your warranty coverage.
Our complete solar panel cleaning service includes inspection of your entire array, gentle cleaning of all panel surfaces and frames, and a post-cleaning assessment of your system’s condition. We remove all dust, pollen, bird droppings, and other debris that can impact performance.
We also check mounting hardware for signs of corrosion or loosening, inspect electrical connections for obvious issues, and look for potential bird nesting sites or other problems that could affect your system. If we spot any concerns, we’ll document them and provide recommendations.
Every cleaning includes before and after photos so you can see the difference, plus a brief report on your system’s condition and any maintenance recommendations for keeping your panels performing at their best.
The most reliable indicator is declining energy production that can’t be explained by weather or seasonal changes. Check your system’s monitoring data or monthly energy bills—if production drops gradually over time, dirty panels are often the culprit.
Visual inspection can also reveal obvious problems like bird droppings, thick dust accumulation, or staining on panel surfaces. However, even panels that look relatively clean can have efficiency-reducing buildup that’s not immediately visible from ground level.
In Hemet’s climate, we generally recommend proactive cleaning every 6 months rather than waiting for obvious performance problems. This approach prevents the kind of stubborn buildup that becomes harder and more expensive to remove if left too long.
