Why Gus’s Solar Is San Antonio’s Preferred Solar Panel Cleaning Company
We’ve been cleaning panels in San Antonio long enough to know what this city throws at a rooftop array. Live oak pollen in March. Cottonwood fuzz in May. Dust from construction off 1604. Hail in the spring. And the occasional grackle roost that turns a panel into a mess. Homeowners call us because we show up when we say we will, and we don’t leave until the job is done right.
Gus’s name is on the truck, on the building, and on every invoice. That matters in a city where solar companies have come and gone over the years. When you call (877) 550-6892, a live person answers, 24/7. Not a voicemail. Not a ticketing portal. We quote a price up front, and that’s the price you pay. The 90-Day Done Right Promise backs every cleaning and inspection we do in San Antonio. If it’s not right, one call brings Gus back to make it right, in writing, no fine print.
Our crew is background-checked and uniformed. You’ll know exactly who’s on your roof before they climb the ladder. We work on Panasonic panels, Canadian Solar arrays, JinkoSolar systems, and everything in between. If your panels are still under manufacturer warranty, we clean them per the manufacturer’s recommended method so you don’t void anything.
Our Solar Panel Cleaning Services in San Antonio
Residential Panel Cleaning
A standard single-family home array in San Antonio, usually 20 to 35 panels, runs $150-$350 depending on roof pitch, accessibility, and how much buildup has accumulated. Two-story homes and steep tile roofs cost more because they take longer and require extra safety rigging. We use deionized water and soft brushes that won’t scratch tempered glass or degrade anti-reflective coatings. One cleaning typically takes 60 to 90 minutes from ladder up to ladder down.
Commercial Array Cleaning
San Antonio commercial arrays cost $5-$12 per panel, with most jobs falling between $800 and $3,500 depending on the size of the system. We clean warehouses off Rittiman Road, office parks near the airport, and retail rooftops along San Pedro Avenue. Commercial cleaning in San Antonio usually means working around HVAC units, skylights, and roof penetrations, so we coordinate with your facility manager to avoid disrupting business hours. Evening and weekend scheduling is available.
Bird & Critter Guard Installation
Pigeons, grackles, and squirrels are a real problem for San Antonio rooftop solar. Birds nest under panels and their droppings eat into production faster than dust alone. Critter guard installation runs $8-$15 per linear foot, and a typical residential array needs 80 to 150 feet of guard, so most San Antonio homeowners spend $700-$1,800. We use galvanized steel mesh that clips to the panel frame without drilling into your roof. It keeps the pests out and protects the wiring from chewing damage.
Debris & Soiling Removal
San Antonio’s tree canopy creates a specific problem for solar arrays. Mature live oaks and crape myrtles drop leaves, pollen, and fine organic dust that hardens onto panel surfaces when it gets wet. A basic debris removal and wash runs $120-$250 for most single-story homes. We also handle the stubborn stuff: sap spots, bird droppings baked on by the Texas sun, and construction dust from the new subdivisions going up around 78219. If your panels haven’t been cleaned in over a year, this is the service that makes the biggest difference in your next CPS Energy bill.
Post-Storm Panel Cleaning
San Antonio sits in a hail corridor where spring storms regularly drop hail over 1.5 inches. After a storm, your panels need more than a wash. They need a careful inspection for micro-cracks, frame damage, and embedded grit along the edges. Post-storm cleaning and inspection runs $200-$400 depending on array size and how much debris is on the roof. We check every panel individually using the IEC 61215 hail-impact standard as our reference point. A panel that looks fine from the ground can be quietly losing efficiency from impact damage you can’t see without a close look and a production test.
Scheduled Cleaning Plans
Most San Antonio homeowners see the best return with twice-yearly cleaning: once in late spring after oak pollen season, and once in early fall before the winter production drop. Annual plans start at $250 for residential systems and $800 for small commercial arrays under 100 panels. We handle the scheduling, send reminders, and lock in your rate for 12 months. If you live in 78201 or 78204 under a heavy tree canopy, we’ll recommend quarterly service and tell you honestly if your panels don’t need it.

Trusted Brands We Service in San Antonio
We clean and maintain panels from Panasonic, Canadian Solar, JinkoSolar, and FranklinWH battery systems, plus every other major manufacturer you’ll find on San Antonio roofs. Most cleaning companies just wash glass. We check connections, combiner boxes, and racking hardware while we’re up there. If we spot a cracked frame or a loose clamp, we tell you the same day with photos, and we can repair it before it becomes a bigger problem. We keep common replacement parts in our San Antonio service vehicles, which means most fixes happen on the first visit instead of waiting for a shipped part.
Common Solar Panel Cleaning Problems We See in San Antonio Homes
- Live oak and crape myrtle soiling: In neighborhoods like Monte Vista in 78201 and King William in 78204, mature trees overhang many rear roof faces. Organic debris from these trees cuts production by 8-15% between cleanings, especially when panels are placed on rear roof faces due to HDRC street-visibility rules.
- Hail-impact micro-cracks: San Antonio gets hailstorms with stones over 1.5 inches. A panel can look intact from the ground but have microscopic fractures in the glass that accelerate degradation. Post-storm cleaning without an impact check misses damage that will quietly eat your production for years.
- Pigeon and grackle droppings: Birds roost under panels and leave droppings that bake onto the glass in the San Antonio heat. The acid in bird waste etches anti-reflective coatings permanently if left too long. Critter guard is the prevention; we install it on roughly a third of the arrays we clean.
- GPS Energy true-up shortfalls: When panels run dirty during June, July, and August, you produce less than your system was designed to make. That means buying more energy back from CPS Energy at retail rates, which directly reduces your annual true-up credit. Dirty panels aren’t just an appearance issue; they’re a line item on your bill.

FAQs - Solar Panel Cleaning in San Antonio
Soiling that drops production 10-15% during June through August directly shrinks your true-up credit because CPS Energy’s net metering cap is sized to your actual usage over the previous 12 months. Dirty panels produce less, which means you buy more energy back at retail rates, and your annual credit comes in lower than it should. A $200 cleaning that restores full production during peak months often pays for itself in a single summer billing cycle. Call (877) 550-6892 and bring us your last true-up statement; we’ll show you the math.
No. Cleaning existing panels does not trigger a Historic and Design Review Commission review in San Antonio. HDRC approval applies to installing new panels or changing their placement. If you already got approval for your array, cleaning, inspection, and maintenance are exempt. Our crew has worked on dozens of HDRC-restricted arrays in 78201 and 78204, and we know exactly what we can do without opening a design-review case.
Within two weeks, ideally. Hail damage to solar panels doesn’t always show up immediately. Micro-cracks spread as panels heat and cool, and a panel that’s producing fine today can lose 5-10% efficiency over the next year because of impact damage. Getting panels cleaned and inspected within 14 days of a storm lets us document condition, catch early damage, and file the paperwork you’ll need for an insurance claim. We’ve done post-storm inspections across San Antonio, from Stone Oak to 78219, and we know what adjusters look for.
Yes, because it’s thicker and harder to clean off once baked on. Bird droppings, especially grackle and pigeon waste, contain uric acid that etches panel glass and permanently reduces output if left for months. Dust washes off with a rinse. Bird waste needs careful removal and sometimes a second pass. On a bungalow in 78201 with a rear-facing array under mature trees, bird debris combined with leaf litter can cut production more severely than dust alone. That directly affects how much CPS Energy credit you earn during peak months. We recommend critter guard for any San Antonio roof where birds roost near the array.
Cleaning itself doesn’t extend the payback period; it protects it. Every month your panels run dirty in San Antonio’s strong sun, you lose production you already paid for. In the hail corridor, regular inspections catch impact damage early so minor problems don’t become panel replacements. A homeowner who cleans twice a year and inspects after every major storm will see their system hit its original production estimate year after year. That’s what keeps your payback calculation honest. Call (877) 550-6892 and we’ll set up a cleaning schedule that matches your roof, your trees, and your CPS Energy billing cycle.
Why San Antonio’s Local Conditions Make Panel Cleaning Different Here
San Antonio’s municipal utility, CPS Energy, runs net metering through its own rules, not the PUC framework that governs investor-owned utilities in most of Texas. The cap: your system can be sized up to 100% of your previous 12-month usage. That means a panel array that’s covered in pollen, dust, or hail debris during the summer isn’t producing the energy your net metering agreement expects. Every percentage point of soiling costs you real money on your true-up statement. In June, July, and August, when San Antonio sees peak irradiance, a dirty array might be losing $25-$60 per month in production. Clean panels produce at full nameplate capacity, which means your CPS Energy credit reflects what your system was actually designed to do.
Then there’s the historic district complication. In Monte Vista in 78201 and King William in 78204, the HDRC requires solar arrays to not be “visually prominent” from the street. In practice, that pushes installs to rear roof faces or behind parapets. Those rear faces often sit under heavy canopy from mature live oaks and crape myrtles. The trees that make these neighborhoods beautiful are the same ones dumping organic debris on your panels. On a King William Historic District bungalow in 78204, our crew cleaned an 8.2 kW SunPower array after a spring hailstorm left cottonwood pollen and crushed leaves caked across the rear-facing panels. The HDRC-mandated rear-roof placement meant the array sat under a heavy crape myrtle canopy, so we removed the debris, inspected for micro-cracks from hail impact, and restored production within 2% of the original estimate. All without triggering a street-visibility review.
That’s the difference between a cleaning company that knows San Antonio and one that just washes glass. We know where your panels sit, why they’re there, and what’s falling on them in every season.
