You invested thousands in solar panels to cut your electricity bills and help the environment. But when dirt, bird droppings, and grime build up on your panels, you’re literally watching money slip away.
Clean panels can boost your energy production by 5-25% immediately. That’s not just better performance—that’s real money back in your pocket every month. Your system was designed to work at peak efficiency, and professional cleaning is the fastest way to get back to those original performance numbers.
Most homeowners don’t realize that rain actually makes the problem worse. Rainwater picks up pollutants, salt, and chemicals on its way down, leaving a film that blocks even more sunlight. That’s why El Sobrante homeowners who clean their panels professionally see dramatic improvements in their energy bills.
All Seasons Window Cleaning Inc. has been serving El Sobrante and the surrounding Bay Area for over 10 years. We’re fully bonded and insured, so you never have to worry about damage to your roof or panels.
We use specialized deionized water technology that leaves your panels completely streak-free without any chemical residue. This isn’t just about looking good—it’s about performance. When we clean your panels with deionized water, they stay clean up to 10 times longer than traditional cleaning methods.
El Sobrante homeowners choose us because we understand the local conditions. We know how the Bay Area’s unique mix of urban pollution, coastal salt air, and seasonal pollen affects your panels. That’s why we recommend cleaning every six months to keep your investment performing at its best.
First, we inspect your entire solar array to identify any issues like bird nesting, damaged panels, or wiring concerns. Safety is our top priority, so we use proper equipment and follow all OSHA guidelines when working on your roof.
Next, we carefully remove any debris, leaves, or bird droppings by hand. Then we use our specialized deionized water system with soft-bristle brushes to gently clean each panel. No high pressure, no harsh chemicals—just pure water that attracts dirt like a magnet and rinses completely clean.
After cleaning, we do a final inspection to make sure everything looks perfect and your panels are ready to capture maximum sunlight. The whole process typically takes 2-3 hours depending on your system size, and you’ll see the difference in your energy production almost immediately.
Ready to get started?
Every solar panel cleaning includes a complete visual inspection of your system. We check for loose connections, damaged panels, and potential safety issues. If we spot anything that needs attention, we’ll let you know right away.
In El Sobrante, we see a lot of bird-related issues with solar panels. Birds love to nest under panels, and their droppings can seriously impact performance. We safely remove any nesting materials and can recommend bird-proofing solutions if needed.
Your cleaning also includes documentation for warranty purposes. Many solar manufacturers require regular professional cleaning to maintain your warranty coverage. We provide photos and service records that protect your investment and keep you in compliance with manufacturer requirements.
Most El Sobrante homeowners benefit from professional solar panel cleaning every 6 months. The Bay Area’s unique conditions—including coastal salt air, urban pollution, and seasonal pollen—can build up quickly on your panels.
If you have trees near your panels or notice a lot of bird activity, you might need cleaning more frequently. We also recommend an extra cleaning after major storms or during wildfire season when ash and debris can accumulate rapidly. The good news is that regular cleaning actually makes each subsequent cleaning easier and more effective.
Absolutely. Studies show that dirty solar panels can lose 15-30% of their efficiency, and we regularly see improvements of 5-25% immediately after professional cleaning. For a typical El Sobrante home with a $200 monthly electric bill, that could mean $30-60 more in monthly savings.
You’ll often notice the difference in your energy monitoring app within days of cleaning. Many of our customers are surprised by how much their production increases. The cleaner your panels, the more sunlight they can convert to electricity, and the more money you save on your PG&E bill.
We strongly recommend against DIY solar panel cleaning for several safety and performance reasons. First, working on rooftops is dangerous—one slip can result in serious injury or death. Professional cleaners have the proper safety equipment and training to work at heights safely.
Second, using the wrong cleaning methods can actually damage your panels. Hard water, soap, or abrasive materials can scratch the glass surface or leave residue that attracts more dirt. Pressure washers can force water into electrical connections or crack panels from thermal shock. Our deionized water system and soft-brush technique protect your investment while delivering superior results.
Yes, we serve El Sobrante and the entire surrounding Bay Area, including Richmond, San Pablo, Berkeley, and other Contra Costa County communities. We’ve been working throughout the region for over 10 years and understand the specific challenges that Bay Area solar systems face.

If we notice any issues with your system during cleaning, we’ll document them and provide recommendations for qualified repair services.
The cost depends on factors like your system size, roof accessibility, and how long it’s been since your last cleaning. Most El Sobrante homeowners find that professional cleaning pays for itself quickly through improved energy production and lower electric bills.
When you consider that dirty panels can cost you hundreds of dollars per year in lost efficiency, professional cleaning is one of the best investments you can make in your solar system. We provide free estimates and transparent pricing with no hidden fees. Many customers are surprised by how affordable it is to protect your solar investment and maximize your energy savings.
