Gus’s Solar cleans residential and commercial arrays throughout Merced, from the older ranch streets in 95340 to the newer subdivisions in 95348. We’re the Solar Panel Cleaning team that shows up in a marked truck, with our own crew, and we know exactly what Merced’s dust and fog do to a panel’s output. Call (877) 550-6892 and we’ll get you scheduled.
Why Gus’s Solar Is Merced’s Preferred Solar Panel Cleaning Company
Gus Petrakis founded this company in 2011 and he still answers the phone. That matters more in Merced than in a lot of places, because Merced homeowners have dealt with plenty of out-of-town crews that quote one thing, show up with another, and vanish when the work goes sideways. We don’t do that. Our background-checked, uniformed crew does the work, and Gus’s 90-Day Done Right Promise applies to every cleaning job: if it’s not right, one call brings him back.
Merced’s agricultural dust and tule fog create a cleaning schedule problem that most national solar companies never mention. We do mention it, because we live here and we see it every October. Our local reputation in Merced is built on honest numbers and work that holds up. A live person answers our phones 24/7, so when a post-storm mess or a harvest dust cloud hits your array, you reach a human, not a voicemail.
We serve Merced directly from our Central Valley operations, so scheduling is fast. Most residential cleanings in Merced happen within a few days of your call, and post-storm calls get priority when we can safely work.
Our Solar Panel Cleaning Services in Merced
Residential Panel Cleaning
We clean rooftop arrays on Merced’s single-story ranches, two-story tract homes, and everything between. Our soft-brush deionized water method lifts the valley dust, tree sap, and bird droppings without scratching the glass or voiding your panel warranty. Most residential jobs in Merced take under two hours from setup to final rinse.
Commercial Array Cleaning
Merced’s commercial rooftops, school arrays, and ground-mount systems run bigger, and soiling on a 50 kW or 200 kW array is real money lost every billing cycle. We schedule commercial solar installations in Merced and cleanings around your operating hours, document before-and-after production readings, and provide the paperwork your accountant or facility manager will want for maintenance records.
Bird & Critter Guard Installation
Pigeons and roof rats nest under panels all over Merced, and their droppings are corrosive as well as filthy. We install galvanized mesh critter guard around the array perimeter after cleaning, keeping birds and squirrels out while still allowing airflow. It’s a one-time fix that prevents the repeating mess and wire-chewing damage we see in Merced neighborhoods with mature trees.
Debris & Soiling Removal
Between almond harvest dust, mowing season, and the occasional wind event, Merced panels collect a mixed layer of organic and mineral soiling. We remove leaves, pollen, and caked dust by hand, then wash the glass with deionized water to avoid the mineral spots that Merced’s hard water leaves behind.

Trusted Brands We Service in Merced
We clean and maintain panels from every major manufacturer, and we’re factory-agnostic: Panasonic, Canadian Solar, JinkoSolar, Enphase, SolarEdge, Tesla, Qcells, REC, and FranklinWH equipment all get the same careful treatment. Because we stock common replacement parts and critter guard materials locally for our Merced routes, we can often handle guard installs and Merced solar panel repairs in the same visit as a cleaning, no second trip required. If your system uses Enphase microinverters or a SolarEdge inverter, we’ll spot-check production readings before and after the wash so you can see the exact output gain in your monitoring app.
Common Solar Panel Cleaning Problems We See in Merced Homes
- Harvest dust coating in the south and east ZIP codes. Homes in 95343 and 95348 sit downwind of almond and walnut orchards, and late-summer shaking kicks up fine silica that settles on panels. By October, we routinely measure 10-20% output loss on arrays that haven’t been washed since spring.
- Tule fog residue turning panels hazy. Merced’s November-through-February fog doesn’t just block the sun. It deposits a fine, sticky film on the glass that trapped winter dusts and makes spring cleaning harder if it sits too long. A pre-fog cleaning in late October or early November makes a measurable difference in winter production.
- Roof rats and pigeons nesting under panels. Merced’s older neighborhoods with mature trees, especially in 95340 and 95341, see regular nesting under arrays. Droppings degrade the glass, and rats chew wiring and connector housings. Cleaning without critter guard just resets the problem.
- Low-slope ranch roofs holding dust and debris. The 1950s-to-1980s ranch houses that dominate 95340 and 95341 often have shallow roof pitches. Dust and leaves don’t slide off; they sit, pile up, and create uneven soiling that makes individual panels underperform while the inverter-level numbers look less concerning. We check module-level production when we clean for exactly this reason.
Pricing for Solar Panel Cleaning in Merced, CA
A typical residential panel cleaning in Merced runs $150-$300 for arrays up to about 30 panels, depending on roof pitch, accessibility, and how heavy the soiling is. Larger or two-story homes with steep access generally fall in the $300-$500 range. Commercial arrays are quoted by the panel or per kW; most small-to-mid commercial cleanings in Merced land between $800 and $2,500. Critter guard installation typically adds $400-$900 depending on the array perimeter. Scheduled cleaning plans, where we come out twice a year, run $250-$500 per visit with priority scheduling.

FAQs - Solar Panel Cleaning in Merced
Schedule your main solar panel maintenance and monitoring in Merced cleaning for late September or early October, right after the almond and walnut harvest shaking peaks. In Merced’s 95343 and 95348 ZIP codes, that’s the single highest-impact cleaning of the year, because panels can lose 10-20% of output by October without it. We also recommend a lighter spring cleaning after the tule fog season ends, usually in March or early April, to remove the winter film buildup. Call (877) 550-6892 and we’ll help you pick the right window for your neighborhood.
Yes, and it starts with timing. You want a clean before fog season locks in, because fog weeks produce near-zero generation anyway, so any soiling on top of fog just compounds the loss. A late-October or early-November cleaning gets your panels clear before the fog settles in, and a spring cleaning clears the residue the fog left behind. Winter cleanings in Merced are also weather-dependent: we won’t send a crew up on a wet, slick roof, but we’ll schedule you for the first safe dry day.
If your panels are dirty, cleaning them will absolutely improve your true-up. The output you lose to soiling in September and October directly reduces the credits you bank before winter. A Merced array that’s down 15% from harvest dust through October is generating 15% less credit heading into the fog months, and that’s exactly when you’re drawing from the grid more. Cleaning before fog season protects your annual production number when it matters most. We can show you before-and-after Enphase or SolarEdge production readings on the day of the cleaning.
Yes, especially if you have mature trees near the roof or live in an established neighborhood in 95340 or 95341. Pigeons and roof rats nest under panels all over Merced, and the damage is two-fold: droppings eat into panel efficiency and eventually the glass itself, while rats chew on wiring and connector housings. Installing critter guard after a thorough cleaning is the standard fix, and it’s a one-time cost that prevents the recurring problem.
Merced regularly passes 100°F from June through September, and that heat derates panel output during peak afternoon hours. What heat doesn’t do is replace the losses from dust: a dirty panel in a 100°F week is losing output to heat and to soiling at the same time. Keeping panels clean through the hot months means the heat penalty is the only penalty you’re paying. Most Merced homeowners do well with two cleanings a year: one post-harvest, one post-fog. Call (877) 550-6892 and we’ll quote your exact array.
