Fast, Reliable Solar Panel Cleaning Across Floresville
Solar panel cleaning in Floresville costs between $180 and $420 for a typical 20 to 48 panel residential array, and between $600 and $1,800 for larger commercial or agricultural building systems. We schedule most Floresville jobs within two to four business days, and we do not charge a trip fee anywhere inside our home county. If your array sits next to a peanut field, runs alongside a caliche road, or bakes under 100 degree heat from June through September, your panels are working harder and getting dirtier than most sanitized guides will ever tell you.
Call (877) 550-6892 and a live person answers, day or night. No call center in another state. No ticket queue. You talk to someone who knows what a peanut-dust film does to a Qcells panel in July. That’s the whole point.
Key takeaways for Floresville homeowners:
- Peanut-dust and field-road grit in Wilson County can cut array output 15 to 25 percent between cleanings.
- Residential cleaning runs $180 to $420; metal outbuilding arrays run higher.
- We schedule around your co-op’s true-up window so the cleaned array records the best possible kWh offset.
- Every job carries the 90-Day Done Right Promise. If it’s not right, Gus makes it right. In writing.
Why Gus’s Solar Is Floresville’s Preferred Solar Panel Cleaning Company
Gus Petrakis founded this company in 2011 and still puts his own name on the truck, the quote, and the warranty. We grew up doing Solar Panel Cleaning on working properties, not HOA subdivisions with perfect driveways. That’s the reason Floresville acreage owners tend to call us first and call us back. We are not a pop-up cleaning crew working a radius around a national sales funnel. We are an owner-operated outfit with a published address, a license number, and a live person answering the phone 24/7.
Customers across Floresville and Wilson County keep our number saved in their phones for one reason: we do the job right in one trip, and if we miss something, the 90-Day Done Right Promise means one call brings Gus back. We have built our reputation on metal-building arrays and ground mounts near working farmland. That is not a side market for us. It is most of our week.
When someone calls from 78114 and says their ground mount sits a hundred feet off FM 536 next to a peanut field, we know exactly what they are dealing with before we even see the array. That local knowledge is why they do not waste a morning explaining their property to someone from two counties away.
Our Solar Panel Cleaning Services in Floresville
We clean rooftop residential arrays, ground mounts, and the large corrugated-metal agricultural building systems that show up on so many Floresville properties. The job starts with an honest look at your soiling rate, not a canned brochure. Four services cover most of what we do here.
Residential Panel Cleaning
A standard rooftop array in Floresville runs 20 to 40 panels. We clean with soft-bristle brushes and deionized water, never high pressure. High pressure on a hot South Texas afternoon is how you microfracture glass, and we would rather lose a job than lose your warranty. Most residential cleanings are done in two to three hours.

Commercial Array Cleaning
Floresville has a growing number of commercial rooftop and carport systems, along with church and school arrays. These are bigger jobs, often 100 panels or more, and they demand a documented process: scheduled access, clean water sourcing, and a report you can hand to an accountant or a board. We clean commercial arrays across Wilson County with background-checked, uniformed crew members who show up looking like they belong on your property, because they do.

Bird & Critter Guard Installation
Pigeons and grackles love the shaded gap under a ground mount or rooftop rack. Their droppings are worse than any dust, and they will build nests that trap heat and chew wiring. We install critter guard around the array perimeter, matched to your racking, so the birds do not come back and the panels stay producing. This is one of the highest-value add-ons we sell on rural Floresville properties.

Debris & Soiling Removal
This is the service that matters most on Floresville acreage. Peanut dust, harvest chaff, pasture grit, oak pollen, mesquite sap, and the fine red-brown dust that kicks up off every caliche road in Wilson County. It lands on the glass, bakes into a film under three straight weeks of 100 degree sun, and quietly steals 15 to 25 percent of your production. We remove it properly: low-pressure wash, soft agitation, no detergent residue left behind to re-attract dust.

Trusted Brands We Service in Floresville
Gus’s crew has cleaned and serviced Qcells, SunPower, and REC modules on homes and ag buildings all over Floresville. We understand the glass coatings, the frame profiles, and the anti-reflective treatments on each manufacturer’s panels, because we have worked with them for years. That matters when a homeowner calls worried that a cleaning will void a warranty. It will not, when it is done the way the manufacturer specifies. We also work alongside the inverter and battery gear most common out here: Enphase microinverters, Sol-Ark hybrids, FranklinWH batteries, and the occasional older string system still running fine.
Common Solar Panel Cleaning Problems We See in Floresville Homes
- Peanut dust and chaff baked onto the glass. We cleaned a 48-panel ground mount off FM 536 where harvest dust from a neighboring peanut field had cut production by 18 percent in six weeks. The homeowner runs a Sol-Ark hybrid with Enphase microinverters and two Fortress eFlex batteries, so we scheduled the wash before the morning true-up window. Soft-bristle brushes only. The anti-reflective coating stays intact, and the production number comes back.
- High-pressure washing on corrugated metal outbuilding roofs. This is the one that makes us wince. A pressure washer aimed at a panel mounted on a ribbed metal roof forces water under the rib seams and into the roof deck below. We get called out to fix the damage after the fact. Do not let anyone with a gas powered pressure washer near a metal-roof array.
- Ignoring the spring pollen season. A lot of folks clean once after harvest and call it a year. Then the live oak and mesquite pollen comes in March and April, the sap bakes onto the glass through May, and by June the array is running hot and dirty before the real heat even arrives. Two cleanings a year is the minimum on acreage. One is not enough.
- Flat quarterly plans that ignore where the array actually sits. An array next to a shaded ranch driveway soiles completely differently than one on a field road next to working peanut ground. The soiling rate differs three to four times between those two sites. A flat quarterly plan either overschedules one or under-schedules the other. That is why we quote soiling based on your actual conditions, not a spreadsheet template.
Pricing for Solar Panel Cleaning in Floresville, TX

FAQs - Solar Panel Cleaning in Floresville
Next to a peanut field, plan on three to four cleanings a year. Peanut dust and harvest chaff are surprisingly aggressive soiling agents, and they can cut production 15 to 25 percent in six weeks during harvest season. If you are next to cattle pasture, the dust load is lower but you still deal with windblown dirt and whatever the cows kick up near the array. Two cleanings a year is the minimum in our experience, and the best timing is early spring and again right after the fall harvest. Call (877) 550-6892 and we can look at your specific exposure before you schedule.
Yes. We use soft-bristle brushes and low-pressure water on both, but a corrugated-metal roof requires extra care around the rib seams. High pressure forces water under the ribs and into the roof deck, and that is a repair bill no one wants. We also use a different footing approach on metal roofs, staying on the purlins and seams so the panels and the roof both stay intact. Cleaning on a metal ag building is not the same job as cleaning on a shingle roof, and any crew that treats them the same is a crew to avoid.
It will, and it is measurable. If your array is 15 to 20 percent soiled, a proper cleaning brings you back to near nameplate production for the same sunlight. On a co-op bill, that means more of your PV production offsets your load before you pull from the grid, which matters more in Wilson County because co-op export credit rules are less generous than what you would find 30 miles northwest in CPS territory in San Antonio. The cleaned array records a higher kWh reading at the true-up window, and that is the number your bill is built on. We schedule cleanings around your true-up window for exactly that reason. Call (877) 550-6892 and we will time it right.
You do not usually need to shut down the inverter, as long as the cleaning is done correctly and no high-pressure spray is aimed at the junction boxes or connectors. We wash with low pressure and avoid flooding the electronics. The exception is if we are doing a deeper wash around ground-level combiner boxes or if there is damaged conduit, in which case we will ask you to shut the system down before we get on site. We will always check the array visually for damaged wiring or connectors before we start. It is part of the job, not an add-on.
We cannot stop a caliche road from producing dust, but we can make the cleaning hold longer. We use deionized water with no detergent residue, because leftover soap film actually attracts and traps dust and makes the array re-soil faster. We also recommend a more frequent but lighter cleaning schedule for arrays with heavy road-dust exposure, rather than waiting until the array is coated. In some cases, a simple windbreak like a row of native shrubs or a fence line upwind can cut the dust load noticeably. We will tell you straight if a windbreak will help or not, because we want your next cleaning to be lighter, not heavier. Call (877) 550-6892 for an honest read on your site.
If your array sits on acreage in Floresville, off a field road, next to a peanut field, or on a corrugated metal building, you already know the generic cleaning advice does not fit. You need a crew that knows the difference between a shaded ranch driveway and a working field road, and that does not flinch when the job involves standing-seam metal, ribbed steel, or a 100 degree afternoon in July. Call (877) 550-6892 for a free estimate. Gus’s crew will come out, look at your array, and tell you what it actually needs. No pressure. No same-night signature. If a salesman needs an answer tonight, the answer is no. Take two weeks. The price will be the same.
