Sunshine Cleaning Service runs a solar panel cleaning service across Metro Atlanta: deionized-water cleaning at zero pressure, efficiency restored, warranty preserved. Read how often Atlanta panels need cleaning.
Deionized water cleaning at zero pressure. No chemicals, no detergents, no abrasives. Pure water lifts grime, pollen, bird debris, and atmospheric particulates without scratching the photovoltaic surface. Hand-detail final pass for any stubborn spots.
Residential rooftop solar arrays, ground-mounted arrays, commercial solar installations.
Every 6-12 months. Atlanta pollen alone can reduce panel efficiency 15-25% - clean panels harvest more energy.
Workmanship guaranteed - and our methodology preserves manufacturer panel warranties (most warranties void if abrasive cleaners or high-pressure water are used).
Every solar array is quoted on its own, so there is no flat rate to post. Three things set the number: how many panels are up there, how steep the roof is, and how easy the array is to reach. A low-pitch roof with a dozen panels and a clear walkway is a quick visit. A tall, steep roof with a large array, or a ground-mounted system across a wide footprint, takes more time and more care, and the quote reflects that.
You also pay for a visit, not a plan. Most homes do best on the every-6-months rhythm our method page describes, but there is no contract behind it. One clean before the summer sun or a twice-a-year schedule, your call, same price per visit either way.
Getting the number takes minutes. Send a photo of your roof through the quote form, or call, and we scope it from the panel count and the access. Final pricing comes from your free quote request, never a surprise on the day.
In Georgia the answer is driven by pollen. Every spring the pine and oak pollen settles on every flat surface for weeks, and a solar array is a flat surface tilted at the sky. That yellow film does not rinse off in a storm the way it does on a car, because tap water and rain leave mineral residue behind. Pollen alone can cut panel output by 15 to 25 percent until it is removed.
So the rhythm that works here is every 6 to 12 months, timed to the seasons. A post-pollen clean in late spring restores the array before the long summer sun, which is when the panels earn the most. A second clean in the fall clears the summer dust, bird debris, and leaf fragments before the shorter winter days. Properties under heavy tree cover, near construction, or with a lot of bird activity sometimes need a quarterly visit. Arrays in open, low-particulate spots can stretch to once a year.
If you are not sure where your roof falls, send a photo. Pollen film, streaking, and bird debris are easy to see from a driveway shot, and we will tell you honestly whether it needs a clean now or can wait a season.
Yes - measurably. Studies and our own pre/post measurements show 10-25% efficiency loss from heavy pollen, dust, and bird debris in Metro Atlanta. Clean panels generate more kilowatt-hours, which means faster ROI on the panel investment.
Not when proper methodology is used. Most solar panel warranties REQUIRE deionized-water cleaning and prohibit abrasive cleaners, high-pressure water, and chemical detergents. We follow manufacturer specs.
Atlanta climate: every 6-12 months minimum. Properties with heavy tree pollen, bird activity, or proximity to construction zones may need quarterly cleaning. Panels in low-particulate areas can stretch to annual.
Tap water leaves mineral residue (calcium, magnesium, silica) on panels that bonds in sun and gradually reduces light transmission. That's exactly the problem the cleaning is meant to solve. Deionized water is mineral-free, leaves no residue, and is what's actually needed.
There is no flat rate because every array is different. The quote depends on the number of panels, the pitch of the roof, and how easy the array is to reach. It is priced per visit, with no contract. Send a photo of your roof through the quote form and we scope it in minutes.
Every 6 to 12 months, timed to the seasons. A late-spring clean after pollen season restores output before the summer sun, and a fall clean clears summer dust and debris before winter. Heavy tree cover, nearby construction, or lots of birds can push that to quarterly.
You can, but two things work against you. Tap water leaves mineral residue that bonds in the sun and reduces light transmission, which is the problem cleaning is meant to fix, so it takes deionized water to do it right. Most panel warranties also require deionized-water cleaning and prohibit abrasive cleaners, high pressure, and detergents. And it means working on a roof around a live electrical system. If you do it, use purified water, zero pressure, and a soft brush. Most owners decide the ladder is not worth it.
No. Rain knocks some loose dust off, but it leaves mineral residue behind when it dries, and it does nothing for the pollen film that bonds to the glass in spring or for bird debris. After a storm an array often looks streaky rather than clean. Deionized water at zero pressure lifts that film without leaving anything behind, which is why the panels come back to full output after a professional clean and not after a rain.
Late spring, right after pollen season ends, is the single most valuable clean. The pine and oak pollen that coats everything for weeks settles on the array and cuts output by 15 to 25 percent until it is removed, and summer is when the panels earn the most. A second clean in the fall clears summer dust, bird debris, and leaf fragments before the shorter winter days. That is the every 6 to 12 months rhythm.
Bird droppings are the worst kind of shading. A single hard spot on one cell can drag down the output of the whole string it sits on, and it does not rinse off in the rain. We lift it with deionized water and a soft brush, then hand detail any stubborn spots. If you have heavy bird activity, that is one of the reasons to move toward a quarterly clean instead of twice a year.
It is not something we recommend for homeowners. A solar array is a live electrical system on a sloped surface that gets slick the moment water hits it. Our crews are trained for rooftop and ladder work, carry $1 million in general liability, and clean with water-fed poles and zero pressure so no one is standing on the panels. That is the safer and gentler way to do it.
Yes. Residential rooftop arrays, ground-mounted systems, and commercial solar installations all get the same method: deionized water at zero pressure, no chemicals, no detergents, no abrasives. Ground mounts spread across a wide footprint take more time than a rooftop dozen, so they are quoted on panel count and access like everything else. Send a photo or an address and we scope it.
