San Clemente gets plenty of sunshine, but being this close to the coast also means dealing with marine layer, salty breeze, and sandy buildup on your solar panels. Most of the homeowners we talk to here didn’t realize how fast that stuff can block sunlight and slow down power production. But once we clean them? Night and day difference.
One couple in the Talega area gave us a call last summer. They thought their system was underperforming and were ready to bring in the solar company for a checkup. We went up on their Spanish tile roof and found layers of fine grit and dried sea spray baked onto the panels. We cleaned everything with our soft-brush and deionized water setup, and by the weekend, they saw their energy output bounce back by over 20 percent. No tech problem. Just dirt.
Why San Clemente Panels Need Extra Attention
This town’s right up against the Pacific, and that ocean air carries all kinds of stuff—salt, sand, fog, moisture. The marine layer settles every morning and sticks around longer during spring and early summer. It leaves a light film that turns into a heavy coat over time. Then you’ve got wind-blown dust from nearby canyons and grit from all the palm trees around neighborhoods like Forster Ranch, Marblehead, and Southwest San Clemente.
That combo means panels need more love here than in other parts of Orange County. Even if your house is a few blocks inland, the salt still finds its way to your roof.
What Happens When Panels Get Dirty
It doesn’t take much grime to start blocking sunlight. Solar panels are designed to grab as much light as possible—but that only works if the glass is clean. A thin film might not look like much from the ground, but it can mean a 10–25% drop in output. And that means higher energy bills and less value from your solar setup.
If you’ve got an app to monitor your system, you’ll start to see the production curve flatten. And if you don’t? You’ll just feel it in your monthly bill.
How Often Should You Clean Panels in San Clemente?
We recommend at least twice a year for most homes here. But if you’re right on the bluff, close to the beach, or have flat-angled panels that don’t shed dirt easily, every 4 months is better. Homes near Avenida Pico, or down by Calafia, tend to see salt buildup faster due to morning fog and wind off the water.
We’ve got regular customers in Sea Summit, Rancho San Clemente, and Shorecliffs who are on a 3-times-a-year schedule. It keeps things consistent and saves money in the long run.
Don’t Count on Rain
People assume the occasional rain will rinse off the panels. But here’s what really happens: the rain moves dirt around, then it dries and leaves behind mineral spots from both the rainwater and the salt already on the panel. It actually makes the situation worse if the panels weren’t cleaned properly to begin with.
How BJ’s Window Cleaning Does It Right
We don’t just hose things down and call it done. Our process is designed for solar panels—especially coastal ones that deal with sticky salt, mist, and bird droppings.
- We use deionized water, which dries clear and doesn’t leave mineral spots
- Our brushes are soft and solar-safe—no scratches, no pressure damage
- No soaps, detergents, or anything that leaves behind a film
- We take before and after photos so you can see the difference
We’re also careful on your roof. We use ladder pads and protect gutters and tiles. No boot prints across the house, and we clean up when we’re done.
Local Story We Won’t Forget
A homeowner in the Riviera District told us he thought his solar system was aging out. The panels were installed five years ago, and lately the energy bill just kept going up. We checked it out and found bird droppings, hard water spots, and sea fog buildup layered across all 22 panels. We cleaned everything, showed him the photos, and three days later he emailed to say his daily output jumped 28%.
He canceled the service call he had scheduled with his solar installer. Now we come by every spring and fall. Easy.
We Clean Homes All Over San Clemente
If you’re in:
- Forster Ranch
- Marblehead
- Rancho San Clemente
- Talega

We’ve cleaned roofs in all of them. Whether your place has Spanish tile, asphalt shingles, or a flat modern build with edge-mount panels, we’ve got the tools and experience to do it right.
Commercial and Multi-Unit Solar Cleaning
We also clean solar panels for small businesses, offices, churches, and multi-family buildings in San Clemente. If you’re a property manager or business owner, we can work around your schedule and minimize disruption. Recurring plans are available—or just call us when you need us.
One of our regular clients is a commercial property near the outlet mall. They’ve got a mix of solar across carports and flat rooftops. We clean it quarterly and keep detailed records, which makes it easy for them to track performance over time.
What You Can Expect From Us
- Quick, flat-rate quotes based on roof type and panel count
- On-time arrival with a quick text or call beforehand
- Respect for your home, neighbors, and landscaping
- Photos before and after the job is done
- Optional notes if we spot damage, shade issues, or wiring problems
Most cleanings take under 90 minutes. And no, you don’t have to be home if we can access the roof safely. We’ll follow up with everything once it’s done.
Can You Clean Them Yourself?
You could try—but most people either don’t have the tools or end up making it worse. Hose water leaves spots. Rough brushes scratch. And trying to balance on a tile roof with a bucket isn’t anyone’s idea of a relaxing weekend.
We had a guy in Forster Ranch who used a sponge mop and some soap. He ended up with smeared streaks across the panels and called us a week later to fix it. No judgment—it happens more than you’d think.
When’s the Best Time to Book?
If it’s been over six months, now’s good. Especially before peak summer or after heavy fog season. If you’re seeing streaks, hard water lines, or just lower output on your app, the panels are probably due.
We can clean before home inspections, property sales, or just as part of your regular maintenance. And if you want us to set a reminder for next time, we can do that too.
