Fast, Reliable Solar Panel Cleaning Across Temple City
Solar panel cleaning in Temple City typically costs $150-$350 for a standard single-family home, and most jobs are done within one to three days after you call. That’s the honest range, and we’ll give you a firm number before we touch the roof. Temple City’s position in the LA Basin inversion layer means your panels collect a sooty, fine-particulate film faster than panels out by the coast, and that film quietly costs you kWh every single day. Call (877) 550-6892 and we’ll come out, look at the array, and tell you exactly what it needs.
Why Gus’s Solar Is Temple City’s Preferred Solar Panel Cleaning Company
Gus Petrakis has been running Gus’s Solar since 2011, and he’s the reason our Temple City customers keep calling back. He answers his own phone, he shows up when he says he will, and his name is on the work. We’re not a call center that subcontracts cleaning jobs out to whoever’s available. Gus’s own crew does the job, wearing uniforms and carrying background checks, and they know Temple City roofs because they’ve been on hundreds of them.
Here’s what that looks like in practice: when a Temple City homeowner on Live Oak Avenue calls about a production dip, we can usually be out the same day or the next. We know the 91780 zip code, we know the ranch homes on Daines Drive and the bungalows off Temple City Boulevard, and we know what a San Gabriel Valley summer does to glass. Our Google reviews from Temple City customers consistently mention the same things: we showed up on time, the price didn’t change, and the panels actually produce better afterward.
You don’t need a contract, and nobody will pressure you into anything. Bring us a bill, we’ll bring you the math. The estimate is free. The price we quote is the price you pay. If a salesman needs an answer tonight, the answer is no, and that’s not how we operate anyway.
Our Solar Panel Cleaning Services in Temple City
Our Solar Panel Cleaning team handles arrays on every roof type common in Temple City, from 1940s composition shingles to the clay and concrete tile roofs that dominate the ranch homes built here through the ’60s and ’70s. Here’s what we do most often:
Residential Panel Cleaning
We clean panels on Temple City homes using deionized water and soft brushes, never pressure washers or harsh chemicals. Pressure washing can void panel warranties and etch the glass, so we don’t do it. A typical residential clean in Temple City runs $150-$250 depending on roof pitch and array size, and most homeowners see a production bump of 5% to 15% immediately afterward.
That number jumps higher when the panels haven’t been cleaned in a year or more, which happens more than you’d think. The inversion layer here deposits a film that doesn’t rinse off with rain. It bakes on.

Commercial Array Cleaning
Flat and low-slope commercial arrays on Temple City’s retail strips and school campuses collect dust and smog film the same way residential arrays do, but the square footage makes the losses add up fast. We clean commercial systems throughout 91780, including rooftop arrays and ground mounts. Commercial cleaning in Temple City generally runs $0.08-$0.15 per watt depending on accessibility, minimums around $300. If you’re managing a property or running a business, we can schedule cleanings around your hours.

Bird & Critter Guard Installation
Pigeons love the space under solar panels, especially on the clay and concrete tile roofs that cover so much of Temple City. They nest under arrays, and their droppings are acidic enough to etch panel glass over time. That’s not a cosmetic problem; it’s a measurable soiling loss. We install galvanized mesh bird and critter guards around the array perimeter, powder-coated to match, and they stop the problem without hurting airflow. Bird guard install on a typical Temple City roof runs $500-$900, and it’s worth every dollar if pigeons have already moved in.

Debris & Soiling Removal
Mature trees are everywhere in Temple City, especially the camphor and sycamore trees in the older neighborhoods. Leaves collect under and between panels, blocking airflow and creating hot spots that trigger microinverter faults on Enphase systems especially. We clear debris, clean the glass, check for hot spots, and tell you if we see anything that needs a deeper look. Debris removal is typically bundled into a full clean; on its own it runs $100-$200 depending on how much material has built up.

Trusted Brands We Service in Temple City
We clean and inspect arrays built with Qcells, REC, SunPower, and Panasonic panels, plus Enphase and SolarEdge inverters, all of which we see regularly across Temple City. We don’t stock parts for one brand and shrug at the others. We know how each manufacturer wants their glass handled, which cleaning methods are warranty-safe, and what production numbers to expect from a clean array. If your system is still under a performance warranty, we can help you document cleanings so you’ve got a record if a claim ever comes up.
Common Solar Panel Cleaning Problems We See in Temple City Homes
- Inversion layer smog film. Temple City sits in the LA Basin, and fine particulate matter accumulates on panels faster than the typical 0.5% annual degradation rate would predict. We recommend six-month cleanings here, not annual, for most homes because of it.
- Pigeon pressure on tile roofs. The clay and concrete tile roofs on 1950s-1970s ranch homes give pigeons a protected overhang to nest under. Acidic droppings etch glass and increase soiling losses, and the fix is a bird guard, not just more frequent cleaning.
- Leaf debris and tree sap. Mature camphor, sycamore, and Chinese elm trees in Temple City yards drop leaves and sap onto arrays, creating hot spots that shorten module life and trigger microinverter faults.
- Post-construction dust. Temple City has seen steady renovation work over the last decade, and nearby roof or stucco work throws fine dust onto panels. We see this on homes near active remodels, and a post-construction clean usually restores production fast.

FAQs - Solar Panel Cleaning in Temple City
Every six months for most Temple City roofs. The LA Basin inversion layer deposits fine particulate and photochemical smog film faster than coastal LA cities see, so annual cleanings leave meaningful production on the table. If you’ve got mature trees or a pigeon issue, you may need cleaning every four to five months until the bird guard is installed. Call (877) 550-6892 and we’ll tell you what your roof specifically needs.
No. Cleaning restores production, but it doesn’t change the capacity of an original 60- or 100-amp panel, and many Temple City homes built between the 1940s and 1970s still have original panels that limit how much solar-fed power the house can use. If you’re on NEM 3.0 with Southern California Edison and you’re adding battery storage, the electrical panel capacity question matters more than panel cleanliness. Cleaning helps you get every kWh your array can produce; it doesn’t fix an undersized panel.
Yes. Concrete and clay tile roofs are the most common roofing type on Temple City ranch homes, and they’re also the easiest for pigeons to nest under because of the tile profile. We use mesh guards that follow the tile contours and fasten without cracking tiles, and we include a check for existing nesting. The guard install pays for itself on the first avoided cleaning of etched glass.
Yes, and in Temple City this matters more than in LADWP territories. Temple City is entirely within Southern California Edison’s service territory, and NEM 3.0’s reduced export rates mean every kWh your panels fail to produce because of soiling costs you more than it would have under the old rules. A dirty array under NEM 3.0 isn’t just inefficiency; it’s money you’re buying back at retail rates. Clean panels produce more, and more production means a smaller true-up bill. Call us for a free estimate, and we’ll explain the numbers off your actual bill.
Panels in Temple City typically degrade at 0.5% to 0.7% per year under manufacturer specs, but soiling from the inversion layer can add another 5% to 18% of production loss on top of that when panels go uncleaned for a year or more, especially in the dry season. Cleaning doesn’t reverse degradation; it removes the added loss. Our crew serviced a 1960s ranch on Daines Drive where a new Tesla system had lost 18% of its expected kWh offset after one dry season. A full debris and soiling removal, plus a bird guard, brought the array back to within 3% of its post-install production estimate.
