AfterFast, Reliable Solar Panel Cleaning Across Austin
Solar panel cleaning in Austin typically costs $180 to $340 for a standard residential array, and most jobs are done in under two hours. We’re the Austin crew that shows up in uniform, walks your roofline before touching a ladder, and leaves before lunch. If your monitoring app has shown a slow dip in production over the last few months, the fix is usually simpler than you think. Call (877) 550-6892 and we’ll tell you straight whether your panels need a wash or something else entirely.
Why Gus’s Solar Is Austin’s Preferred Solar Panel Cleaning Company
Gus Petrakis put his own name on this business in 2011, and he’s the one who picks up the phone when you call. That matters in Austin, where a lot of solar work gets farmed out to crews that drive in from San Antonio or Georgetown and vanish after the job. We keep a published address here, our own trucks, and our own people on every roof.
Austin homeowners tell us the same thing again and again: they want a name they can verify, not a call center. Every tech on our team is background-checked and uniformed, so you know who’s walking your property before they ever step onto the driveway. Our reputation across East Riverside, Crestview, and Tarrytown is built on showing up when we say we will and charging what we quoted.
If something’s not done right, our 90-Day Done Right Promise covers it in writing. One call brings Gus back. No ticket numbers, no escalation queue.
Our Solar Panel Cleaning Services in Austin
Residential Panel Cleaning
We clean residential arrays all over Austin, from tight single-story ranch homes in Allandale to newer builds in Mueller. A typical home with 20 to 30 panels takes about two hours. We use soft brushes and deionized water, never harsh chemicals, because Austin’s hard water leaves mineral spots if you’re not careful about the rinse.
Commercial Array Cleaning
Flat-roof commercial systems on East Austin warehouses and South Congress office buildings collect dust and diesel soot faster than residential arrays. We clean commercial arrays on a schedule that works around your business hours, usually early mornings. If you run a business off East Cesar Chavez or along the 78724 corridor, call us and we’ll set up a recurring plan that keeps your production numbers up.
Bird & Critter Guard Installation
Grackles are the big one here. They roost in the mature live oaks all over 78704 and 78723, and their droppings create hot spots on panel glass that accelerate degradation. We install critter guard around the array perimeter to keep birds and squirrels out from under your panels. It’s a one-time fix that saves you from paying for repeated cleanings.
Debris & Soiling Removal
Live oak pollen in March, pecan leaves in November, construction dust from all the infill building in 78702. It lands on your panels and bakes into the glass under 105°F sun. We remove the built-up soiling that plain rain won’t touch, then document the before and after with production data so you can see exactly what was lost.
Scheduled Cleaning Plans
If you’d rather not remember when to call, we set up quarterly or biannual cleaning plans for Austin homeowners. Your array gets cleaned on a set calendar, you get a text when we’re on the way, and the price stays the same year-round. This is the most common plan we write for customers in 78703 and 78725 who want to stop thinking about panel maintenance entirely.
Post-Storm Panel Cleaning
After a hailstorm or a heavy wind event, we come out and clear leaves, branches, and grit from your panels, plus check for microcracks and loose mounting hardware. Austin’s spring storm season runs March through May, and the sooner we get debris off the glass, the less chance there is of permanent soiling damage.

Trusted Brands We Service in Austin
Our team cleans and maintains arrays built with Panasonic, Canadian Solar, JinkoSolar, and FranklinWH equipment, among others. We don’t push one brand over another, but we know the monitoring apps and hardware for each well enough to spot production issues while we’re up there. If you have a Panasonic panel paired with a FranklinWH battery and the numbers look off, we can usually tell you why during the cleaning visit.
Common Solar Panel Cleaning Problems We See in Austin Homes
- Live oak pollen film: Austin’s live oaks drop a yellow-green pollen coat every March and April. If it’s left on the glass through May, it hardens into a film that plain water won’t remove and can permanently reduce panel output by several percentage points.
- Grackle droppings on East Austin arrays: Grackles roost in the big pecan and oak trees along 78702 and 78723. Their droppings are acidic and bake into hot spots on panel surfaces under direct sun, which degrades the anti-reflective coating over time.
- Construction dust from infill builds: Austin’s rapid lot-by-lot redevelopment kicks up dust and fine particulate that settles on nearby panels. If a new build went up next door, your production probably dipped without you noticing.
- West-facing array soiling: Many Austin homeowners orient panels west to chase Austin Energy’s late-afternoon time-of-use credit. West-facing glass catches more late-day sun and more evening dust, making consistent cleaning more consequential for local payback math than it is in Round Rock or Pflugerville.
Pricing for Solar Panel Cleaning in Austin, TX
A standard residential panel cleaning in Austin runs $180 to $340, depending on panel count, roof pitch, and access. Single-story arrays under 25 panels usually land on the lower end. Steep two-story rooflines or arrays with heavy soiling run higher. Commercial cleaning is quoted per project, but a flat-roof system under 100 panels typically falls between $400 and $800 per visit. We quote the price before we show up, and that’s the price you pay. Call (877) 550-6892 for an exact number on your system, no signature needed tonight. Take two weeks to think about it. The price will be the same.

FAQs - Solar Panel Cleaning in Austin
Because Austin Energy credits your exported production at its annually recalculated Value of Solar rate, not the retail rate, every kilowatt-hour lost to soiling is worth less than the same kWh would be under a standard net-metering utility. That means dirt doesn’t just cost you generation, it costs you a city-specific credit that’s already below retail. Most Austin homeowners should clean twice a year, and those with heavy oak canopy or grackle pressure should consider quarterly. Call (877) 550-6892 and we’ll look at your true-up history to recommend a real schedule.
No. Cleaning itself works fine in the heat, but the heat does suppress your panel output by roughly 0.3 to 0.5 percent per degree above 25°C. That thermal derating is exactly why removing soiling matters more here: you’re already losing production to heat, so adding dirt on top of that compounds the loss. We schedule Austin cleanings for early mornings to keep the glass cool and avoid thermal shock from cold water on hot panels.
It can, over time, if chewed wiring or nesting material causes a fault that trips your system offline. Austin Energy’s interconnection rules require your array to shut down safely during grid events, and a fault from critter damage can do that at the worst time. If you see grackles or squirrels around your panels, get critter guard installed before the wiring gets gnawed. We’ll document the condition for you, which helps if Austin Energy ever asks for an inspection report.
Yes, but only if you document the soiling before it’s cleaned. We photograph the array, pull the production logs from your monitoring app, and record the before and after so you have an evidence trail if your true-up credit looks wrong. Without documentation, Austin Energy has no reason to adjust your estimate. After a heavy storm in Austin, call us within a week and we’ll get you the records you need.
Because Austin Energy’s time-of-use rate rewards late-afternoon production, and west-facing panels are the ones capturing that credit. A dirty west-facing array loses more of its financial value per panel than an east-facing or south-facing one, since the highest-value production hours are exactly when the glass is also collecting the most evening dust and pollen. That’s an Austin-specific math problem, not a generic solar one. Call (877) 550-6892 and we’ll walk through what your specific array orientation means for cleaning frequency.
