Denver’s dry, high-altitude air keeps one problem off your roof: the mold and algae that coat panels in wetter, coastal climates barely get a foothold here. What settles on your glass instead is wind-driven dirt, fine dust, storm debris, and a steady layer of pollen, and all of it dulls how much sun your panels actually take in. A hazy array quietly produces less than a clean one.
We clean residential solar panels with purified water and a soft brush, reaching rooftop and ground-mounted arrays from the ground. That means no one walks your roof and no streaks are left behind on the glass. Here at Platinum Pressure Washing, we treat keeping panels clear as a gentle, deliberate job, not a power-washing one.
If your panels look dusty or your output has slipped, give us a call at (303) 931-7300 and we’ll talk through your setup.
Whatever your setup looks like, there’s a good chance we already clean it. Here are the residential installations we work on most.
The most common residential setup, with panels mounted up on the roof. We reach every one of them with water-fed carbon-fiber poles from ground level, so the array stays exactly where your installer put it. Rooftop panels also sit highest in the path of the dust and pollen moving across the Denver area, which is what dulls them fastest.
Ground-level arrays sit on a rack or frame out in the yard. The soft brush and purified water reach every panel face for an even, spot-free clean, and the rinse water runs off to the surrounding ground rather than back across the panels.
Because we’re right up against every panel with the pole and brush, we tend to notice things a homeowner on the ground wouldn’t: a loose connection, a cracked panel, visible damage on a cell. When we spot something, we tell you plainly what we see.
From there, we point you in the right direction. Solar electrical and component work belongs with a specialist, so we flag the issue and recommend you have it looked at, giving you the chance to act on it before it costs you output.
Beyond the clean itself, here’s what makes us the right crew to put a pole and brush to your array.
Using purified water and carbon-fiber poles, we clean multi-story buildings and solar panels from the ground up, no ladders, no streaks, just a spot-free finish. For your array that means the panels stay untouched by ladders and foot traffic, with nothing to scratch, crack, or knock out of alignment while we work. It’s the gentle, warranty-safe approach a delicate rooftop system calls for, and it skips the pressure and harsh processes that can void a panel’s manufacturer warranty.
Purified water leaves no mineral residue or streaking behind on the glass, so your panels come out with an even, clear surface top to bottom. That clear surface is the whole point of cleaning them: sunlight reaches the cells without a film in the way. Ordinary tap water dries into a fresh set of mineral spots of its own, so we clean with purified water from start to finish.
We use eco-friendly products safe enough that your kids, pets, and neighbors can walk right by while we work, no harsh chemicals, no killed landscaping. Solar cleaning leans almost entirely on purified water and a soft brush anyway, so there’s no harsh runoff onto your roof, your yard, or the plants sitting beneath a ground-mounted array.
From your first call to the final look-over, here’s how a solar cleaning goes.
You call or request a quote, and we talk through your property and your array by phone. Pricing is scope-based off our standard tiers, and we’ll reassure you up front on the gentle, warranty-safe method we use.
We confirm a date, weather permitting, then arrive, do a quick walkthrough, and protect the surrounding area. We also check water access. Our trucks are self-contained and can bring purified water when a site doesn’t have any.
This is the actual clean. We feed purified water through water-fed carbon-fiber poles, up to twenty-four feet, and work a soft brush gently across each panel face from the ground. There’s no pressure on the glass at any point, and the purified water rinses away clean so nothing dries back onto the surface.
We close out with a walkthrough alongside you, and we don’t call the job done until you’re happy with how the panels look. Only then do we invoice.
Most residential solar cleans fall between the tiers below, depending on the size and number of panels and how much reach the job takes. Every job is confirmed with an estimate first, so you know the number before we start.
A $300 job minimum applies, and the final price adjusts for scope factors like no water on site, off-hours scheduling, travel, or unexpected complications.
If you’re a repeat customer or bundling solar cleaning with another job, such as a house wash, ask about our Preferred Customer discount when you get your estimate. It’s also worth asking about any current promotions we’re running.
Two guarantees back every solar cleaning we do, and both apply to your home.
We stand behind every job with a satisfaction guarantee, if you're not happy, we'll come back as many times as it takes to make it right, because the customer is number one. That's why the closing walkthrough happens before you're ever billed.
We carry insurance and back our work, so your property is protected while we're on the job. Your roof, your array, and everything around it are covered the whole time our crew is on site.
No. Our method is designed to protect your panels’ manufacturer warranty. We clean with purified water and a soft brush rather than high pressure or harsh processes, which is exactly the kind of gentle approach that avoids the sort of cleaning that can void a panel warranty.
For most Denver-area homes, an annual or semi-annual clean is plenty. On panels, it’s the dust, wind-driven grit, and pollen that build up and cut into output, so a regular light clean keeps them producing without an aggressive schedule.
Not necessarily. With access to the array and a water source, we can complete the job whether or not you’re there. We arrange a before-and-after walkthrough or sign-off wherever possible, so you can see the finished result for yourself.
Cleaner panels mean more sunlight reaching the cells, and it all starts with a free, no-obligation estimate. Whether your array is up on the roof or mounted in the yard, we’ll scope the job, give you a straight price, and get your Denver home on the schedule. Call us at (303) 931-7300 to set up your solar panel cleaning, and we’ll take it from there.
