Dust, pollen, and bird droppings don’t just make your panels look bad. They’re costing you money every month by blocking sunlight from reaching your solar cells.
Research shows dirty solar panels can lose up to 40% of their efficiency. In San Bernardino’s dusty environment, that efficiency drop happens faster than you think. Professional cleaning restores your panels to peak performance, often increasing power output by 12-25% immediately after service.
Clean panels mean lower electric bills, better return on your solar investment, and equipment that lasts longer. You’ll also catch potential problems early before they become expensive repairs.
All Seasons Window Cleaning Inc. has been serving San Bernardino County for years, and we understand what your solar panels face here. Desert dust, seasonal winds, and urban pollution create a perfect storm for dirty panels.
We’re not just window cleaners who decided to clean solar panels. We’ve invested in specialized equipment designed specifically for solar panel maintenance, including deionized water systems that leave no mineral deposits and thermal cameras that detect problems before they cost you money.
Our team knows which neighborhoods get hit hardest by dust storms, where bird problems are worst, and how San Bernardino’s unique climate affects your solar system’s performance. That local knowledge makes a difference in both cleaning effectiveness and maintenance scheduling.
We start with a visual inspection of your entire solar array, checking for damage, bird nesting, or hot spots that indicate potential problems. Our thermal camera scan detects issues invisible to the naked eye.
Next comes the cleaning process using deionized water and specialized brushes designed for solar panels. This water is mineral-free, so it dries without leaving spots or residue that attracts more dirt. We clean from the ground using water-fed poles whenever possible, eliminating unnecessary roof traffic.
Bird droppings and stubborn buildup get individual attention with biodegradable solutions that won’t damage your panels or void warranties. We finish with a rinse using our purified water system and a final inspection to ensure every panel is spotless and functioning properly.

Every solar panel cleaning includes our comprehensive thermal camera scan to detect hot spots and failing cells before they damage surrounding panels. This early warning system has saved our San Bernardino customers thousands in repair costs.
We also provide bird deterrent consultation and can install protective measures to keep pigeons and other birds from nesting under your panels. Bird problems are common in San Bernardino, and their droppings are particularly damaging to solar efficiency.
Our service includes detailed documentation with before and after photos, so you can see exactly what we accomplished. We’ll also provide maintenance recommendations specific to your location, system type, and the environmental challenges your panels face throughout the year.
Most San Bernardino homes need professional solar panel cleaning every 3-4 months due to our dusty environment and seasonal wind patterns. However, your specific schedule depends on several factors.
Homes near busy roads, construction sites, or agricultural areas may need quarterly cleaning. Properties with mature trees that block wind might stretch to twice yearly. The key is preventing mineral deposits from etching into your panels permanently.
We recommend monitoring your system’s energy output through your inverter app or monitoring system. A noticeable drop in production during clear weather usually indicates it’s time for cleaning.
Yes, professional cleaning typically increases solar panel efficiency by 12-25% immediately after service. The exact improvement depends on how dirty your panels were and what type of buildup they had.
Research from Duke University shows that dust and pollution can reduce solar panel efficiency by up to 25%. In San Bernardino’s environment, even a few weeks of dust accumulation can block significant amounts of sunlight from reaching your solar cells.
Bird droppings are particularly problematic because they create concentrated shadows on your panels. Just one dropping can reduce the output of an entire panel string, making professional removal essential for maintaining peak performance.
We strongly recommend against DIY solar panel cleaning for several safety and equipment reasons. Roof work is inherently dangerous, especially during San Bernardino’s hot summer months when surfaces become extremely hot.
Using the wrong cleaning products or techniques can void your warranty or damage the panels’ anti-reflective coating. Garden hoses and household cleaners often leave mineral deposits that attract more dirt, making the problem worse.
Professional equipment like deionized water systems and specialized brushes clean more effectively while protecting your investment. We’re also insured for roof work and equipment damage, which your homeowner’s insurance likely doesn’t cover for DIY maintenance.
Our comprehensive service includes visual inspection of your entire solar array, thermal camera scanning to detect hot spots or failing cells, and thorough cleaning using deionized water and specialized equipment.
We clean each panel individually, paying special attention to bird droppings and stubborn buildup. All mounting hardware and visible wiring gets inspected for damage or wear. We also clean around the panels to remove debris that could harbor pests.
Every service includes before and after documentation, a detailed report of any issues we discovered, and maintenance recommendations specific to your system and location. We’ll also provide guidance on optimal cleaning frequency based on your property’s unique environmental challenges.
We guarantee streak-free, spot-free results on every solar panel we clean. If you’re not completely satisfied with the cleanliness of your panels, we’ll return to re-clean them at no charge.
Our thermal camera inspection comes with a detailed report of any issues we detect. While we can’t guarantee your panels won’t develop problems, we can guarantee that we’ll identify existing issues that could affect performance or lead to costly repairs.
We’re fully licensed and insured for all work we perform. If our cleaning process somehow damages your equipment, our insurance covers repairs or replacement. However, our specialized techniques and equipment are specifically designed to clean safely without risking damage to your solar investment.
Solar panel cleaning costs vary based on your system size, panel count, current condition, and accessibility. Most San Bernardino residential systems range from $200-$400 for complete cleaning including our thermal camera inspection.
Heavily soiled panels or systems with significant bird droppings may require additional time and specialized treatments, affecting pricing. However, regular maintenance prevents heavy buildup and keeps costs predictable over time.
We always provide free estimates so you know exactly what to expect before we start. Many homeowners find that quarterly service provides the best value while maintaining peak efficiency year-round, especially considering how quickly panels get dirty in our desert environment.
