Your commercial solar system was a major investment designed to cut energy costs and boost your bottom line. But Ontario’s desert dust, smog, and debris don’t care about your ROI.
When panels get dirty, you’re not just losing a little efficiency. You’re watching money disappear every single day. Studies show dirty panels can lose up to 30% of their energy output in just one month. For a typical commercial installation, that’s thousands of dollars in lost production.
Clean panels start paying you back immediately. Most of our commercial clients see the cleaning cost recovered through increased energy production within 2-3 months. After that, it’s pure profit flowing straight to your bottom line.
All Seasons Window Cleaning Inc. has been serving Ontario and the broader Coachella Valley for over a decade, watching businesses struggle with the same problem: solar systems that should be producing more power.
We’re not just another cleaning company. Our technicians are NABCEP certified, meaning we understand solar systems, not just cleaning. We can spot potential issues during cleaning that could save you thousands in repairs down the road.
Ontario’s unique desert environment requires specialized knowledge. The dust here isn’t like regular dirt—it contains particles that can scratch panels if cleaned incorrectly, and the extreme heat makes most cleaning solutions evaporate before they work properly. We show up with the right equipment and expertise for these exact conditions.
We start with a system assessment to identify problem areas specific to your installation. Commercial properties have predictable challenges—areas where dust collects, where mineral deposits build up, and spots where debris tends to accumulate.
Our deionized water system is the key difference. Most companies use tap water, which leaves mineral deposits that actually attract more dirt. Our purified water rinses completely clean, eliminating the calcium and mineral buildup that can void your warranty.
We clean every component that affects performance—not just the glass surface. Desert dust clogs cooling vents and creates hot spots that reduce system lifespan. Our thorough process addresses mounting hardware, inverters, and all areas around your panels. Everything gets a final inspection to ensure optimal performance, and we guarantee you’ll see improved energy production within a week.

Your service includes comprehensive panel cleaning, mounting hardware inspection, inverter area cleaning, and performance verification. We use only deionized water and specialized solar-safe equipment that protects your warranty and extends system life.
Ontario’s location in the Coachella Valley creates unique maintenance challenges. The combination of agricultural dust, desert winds, and industrial activity means panels here get dirty faster than in most areas. We recommend quarterly cleaning for most commercial installations, though some properties near agricultural areas or with heavy bird activity may need more frequent service.
We’re fully insured and bonded, with specialized training in commercial solar cleaning techniques. Our team understands the safety requirements for working on commercial rooftops and around electrical equipment. Every job includes documentation for your maintenance records and warranty compliance.
Dirty commercial solar panels typically lose 15-30% of their energy production, though in Ontario’s dusty environment, losses can be even higher. The exact amount depends on your system size, how long it’s been since your last cleaning, and local environmental factors.
For perspective, if your system normally saves you $5,000 monthly on electricity, a 25% efficiency loss means you’re losing $1,250 every month. That adds up to $15,000 annually in lost production. Most businesses are shocked when they see their energy monitoring data after a professional cleaning—the improvement is usually visible within days.
Most commercial installations in Ontario need cleaning every 3-6 months, depending on your specific location and environmental factors. Properties near agricultural areas, construction sites, or with heavy bird activity may need quarterly cleaning.
The key indicator is your energy production data. If you’re monitoring your system and notice a gradual decline that doesn’t match seasonal changes, it’s time for cleaning. Don’t wait until you’ve lost 20-30% efficiency—that’s money you can’t recover. Desert dust accumulation happens faster than most property owners realize, and what looks like light coating can block significant sunlight from reaching your cells.
Our deionized water system is the biggest differentiator. Most cleaning companies use tap water, which leaves mineral deposits that actually attract more dirt and can void warranties. Our purified water rinses completely clean and eliminates the calcium buildup that’s common in Southern California.
We’re also NABCEP certified, meaning we understand solar systems beyond just cleaning. We inspect mounting equipment, check for potential issues, and can spot problems that could cost thousands in repairs later. Finally, we specialize in desert conditions—Coachella Valley dust requires specific techniques and equipment that most general cleaning companies don’t have.
Absolutely. Most commercial clients see the cleaning cost recovered through increased energy production within 2-3 months. After that, the improved efficiency flows directly to your bottom line for the entire period until the next cleaning.
For example, if cleaning costs $800 and restores 25% efficiency to a system that normally saves $4,000 monthly, you’re recovering $1,000 per month in lost production. The service pays for itself in less than a month, then continues generating additional savings. Remember, every day your panels are dirty is lost production you can’t get back.
We strongly advise against DIY cleaning for commercial installations. Commercial systems present significant safety risks—you’re working at height, around electrical equipment, and often in extreme heat conditions. Improper cleaning techniques can also damage panels or void warranties.
Desert dust contains particles that can scratch glass when cleaned incorrectly, and using the wrong water or cleaning solutions can leave deposits that make the problem worse. Professional equipment like deionized water systems and specialized brushes aren’t typically available to property owners. The liability and potential damage risks far outweigh any cost savings.
Yes, we guarantee you’ll see improved energy production within a week of cleaning, assuming your system was dirty to begin with. If you don’t see measurable results in your monitoring system, we’ll return and re-clean at no charge.
We also guarantee our work won’t harm your system. We’re fully insured and bonded, and our technicians are trained specifically in commercial solar panel cleaning techniques. All work is performed using manufacturer-approved methods that protect your warranty. Most importantly, we stand behind our promise that clean panels will immediately start producing more energy and saving you money.
