You’ll see the difference immediately. Clean panels mean maximum energy output, lower bills, and more savings every month.
Most Rancho Cucamonga homeowners lose 20-30% efficiency before they realize their panels need cleaning. Desert dust accumulates faster than you think, and what looks like light coating blocks significant sunlight from reaching your cells.
With our professional cleaning, you often see an immediate jump in energy production the same day. Your investment starts paying you back properly again.
All Seasons Window Cleaning Inc. specializes in Rancho Cucamonga’s unique desert conditions. We’re NABCEP certified, meaning we understand solar systems inside and out, not just cleaning.
We’ve been protecting solar investments in the Inland Empire for years. Our technicians know exactly how Coachella Valley dust behaves and what it takes to remove it completely without damage.
When we clean your panels, we’re also checking for potential issues that could cost you thousands later. It’s not just about cleaning—it’s about protecting your entire investment.
First, we inspect your system and shut it down safely. No risks, no shortcuts. We know exactly how to work around solar equipment without causing damage.
Next comes the cleaning itself. We use specialized soft-wash techniques with deionized water that removes all minerals. No mineral deposits, no streaks, no damage to your panels or voiding of warranties.
We also clean the areas around your panels, including mounting hardware and inverters. Desert dust doesn’t just affect the glass—it can clog cooling vents and create hot spots that reduce system lifespan. Finally, we restart your system and verify everything works properly.

Every solar panel cleaning includes a complete system inspection. We’re looking for loose connections, cracked panels, or other issues that could affect performance or safety.
In Rancho Cucamonga’s desert climate, we recommend cleaning every 6 months minimum. Some homes need quarterly cleaning, especially if you’re near agricultural areas or have trees that attract birds.
Our deionized water system is specifically chosen for Rancho Cucamonga’s hard water conditions. Regular tap water would leave mineral deposits that actually make your panels dirtier faster. Our purified water rinses completely clean, and we guarantee you’ll see improved energy production within a week of cleaning.
Residential solar panel cleaning typically runs $150-500 depending on system size, roof accessibility, and how dirty your panels are. Most homes with standard rooftop installations fall in the $200-350 range.
We price by the job, not by the hour, so you know exactly what you’ll pay upfront. No surprises, no hidden fees. Consider that a single cleaning often pays for itself within 2-3 months through increased energy production.
If your system needs extra work due to heavy buildup, we’ll discuss that before starting. We always provide free estimates so you know exactly what to expect.

The key indicator is your energy production. If you’re monitoring your system and notice a gradual decline that doesn’t match seasonal changes, it’s time for a cleaning. Don’t wait until you’ve lost 20-30% efficiency—that’s money you can’t get back.
Desert dust accumulation happens faster than most homeowners realize. What looks like a light coating can block significant sunlight from reaching your cells.
No. We guarantee no damage to your panels or voiding of warranties. Our cleaning methods are approved by major solar manufacturers and designed specifically for photovoltaic systems.
We’re NABCEP certified, meaning we understand solar systems, not just cleaning. We use deionized water systems specifically designed for solar panel cleaning with no mineral deposits, no streaks, and no damage to your panels.
Actually, solar companies and manufacturers often specify routine cleaning as part of warranty conditions. Professional maintenance helps protect your warranty coverage.
While cleaning your solar panels yourself is possible, we strongly recommend against it. If you don’t clean them correctly, you risk damaging your solar panel system entirely. Plus, you’re taking time and money away from doing other things.
This isn’t a garden hose and soap situation. Our water filtration system removes all minerals that would leave spots or residue on your panels. We clean each panel systematically, removing dust, bird droppings, and the stubborn buildup that Rancho Cucamonga’s desert environment creates.
Most importantly, we can spot potential problems during cleaning that could save you thousands in repairs later. When it comes to solar panel cleaning, leave it to us.
Dirty solar panels can lose 25-50% of their energy efficiency compared to clean ones. In dust-abundant desert areas like Rancho Cucamonga, panels can lose about 0.2% of their effectiveness per day merely due to dust accumulation.
Do the math, and you’ll see how it adds up to almost 2% efficiency loss in a week, and around 10% within just a month. Bird droppings cause the most notable decline due to their high moisture content and strong adhesion to panel surfaces.
Clean panels can increase energy production by up to 20%, especially in dusty environments like ours. This means improved efficiency, reduced costs, and a faster return on your solar investment.
Our deionized water system is the biggest difference. Most cleaning companies use tap water, which leaves mineral deposits that actually attract more dirt. Our purified water rinses completely clean.
We’re also NABCEP certified, meaning we understand solar systems, not just cleaning. We can spot potential problems during cleaning that could save you thousands in repairs later. We’re fully insured and bonded, and our technicians are trained specifically in solar panel cleaning techniques.
Finally, we specialize in desert conditions. Coachella Valley dust isn’t like regular dirt—it requires specific techniques and equipment to remove completely without damage. We guarantee our work won’t harm your system and that you’ll see improved production.
