People in Yorba Linda know how to plan ahead. That’s why solar is so popular here. But no matter how nice your system is, it won’t perform if it’s covered in grime. We’ve been cleaning panels in neighborhoods like Eastlake, Travis Ranch, and Kerrigan Ranch for years, and it’s always the same story—once they’re clean, the numbers go up.
We had a call from a homeowner near Yorba Linda Blvd last fall. He was worried his solar system was starting to fail. It was only four years old. After we got on the roof, it was clear what happened. Layers of dust and sticky tree residue were coating every panel. After the cleaning, his solar app showed a 24% jump in output over the next week. Nothing was broken. It was just dirty.
What Makes Yorba Linda Panels Dirty?
Even though it feels quiet and clean out here, roofs take a beating. There’s dust blowing in from Chino Hills, ash that drifts over during fire season, and tree debris from all the oaks and eucalyptus around places like Brush Canyon and Fairmont Knolls.
If you’re up in the hills, wind can whip up more dust than you’d expect. Down by Lakeview or Yorba Regional Park, we’ve seen panels stained by bird droppings and water spots from irrigation overspray. Add in car exhaust from traffic on Imperial or Bastanchury, and you’ve got a recipe for grime no matter where you are in town.
How Often Should You Clean Your Panels?
Twice a year works great for most homes in Yorba Linda. We recommend spring and fall, especially before the big heat kicks in and after the dry season settles. If you live in a windier area, have a lot of tree cover, or notice performance dropping faster, three times a year might be smarter.
Rain won’t clean them. That’s a myth. It might rinse off some surface dirt, but it leaves behind minerals and doesn’t touch the stuck-on stuff. We’ve cleaned a lot of panels right after it rained, and they were just as dull as before—only wetter.
Why Cleaning Matters
You paid a lot for your solar system. It’s supposed to save you money. But when the panels are dirty, they can’t pull in light like they should. Less light, less power. And most systems won’t tell you something’s wrong unless you’re tracking the data closely.
We’ve helped customers get back 10 to 30 percent of their solar output just by cleaning. No repairs, no tweaks. Just a solid wash with the right tools.
How We Clean Solar Panels
We don’t mess around with pressure washers or harsh chemicals. That’s the fastest way to damage a panel. Instead, we use:
- Deionized water (leaves no spots or streaks)
- Soft solar brushes that won’t scratch the surface
- Roof-safe ladders and equipment that won’t damage shingles or tile
- No soap, so nothing gets sticky or leaves a film
We also take before and after photos so you can actually see the difference. If anything looks off—like cracked seals or shading problems—we’ll point it out. You’ll know more than when we got there.
Commercial and HOA-Friendly Solar Cleaning
Yorba Linda has a lot of gated neighborhoods and HOAs. We’ve cleaned panels in San Lorenzo, Canterbury, and Vista del Verde communities. If your HOA has noise or access rules, we’ll work within them. Need proof of insurance or a specific appointment time? No problem. We’ve done this before.
We also clean panels on commercial rooftops and larger residential properties. If you’ve got solar on a business building, school, or church, we’ll put together a schedule that keeps things clean and running smooth without bothering your tenants or guests.
Local Story That Stuck With Us
A family near the Black Gold Golf Course called us out of curiosity. They weren’t sure if cleaning really did anything. Their solar system still worked, but they’d noticed the monthly savings were smaller than last year.
We cleaned their 28-panel system and found heavy buildup along the bottom edges. It’s where dust tends to collect and harden. A week later, they said their system output was back to where it had been when it was first installed. They’ve been regulars ever since—and referred their next-door neighbor too.
Trying to Clean Panels Yourself?
It’s doable. But it’s also risky. Most folks don’t have the right ladder setup or water filters. Tap water leaves mineral spots. Rough brushes leave scratches. And if you’re not careful, you can crack the panel seal or slip on your roof. Not worth it for most people.
One guy in Yorba Linda Heights used a pool skimmer and a garden hose. He called us a week later because the panels looked worse. We fixed it—but he said next time he’s calling us first.

Best Time to Schedule
Now’s a good time if it’s been more than six months. Especially if you live near Bastanchury, Yorba Linda Blvd, or anywhere with a lot of tree cover. Spring pollen is rough, and fall brings dry winds that leave a mess.
Most people wait until the panels look really dirty. But by then, you’ve already lost weeks or months of power. A light haze can be just as bad as thick dust when it comes to energy loss.
