Why Gus’s Solar Is Pasadena’s Preferred Solar Panel Cleaning Company
Pasadena is a different animal than the rest of the San Gabriel Valley, and we treat it that way. Gus Petrakis has been running his own crew since 2011, and his name goes on every job we do. When we clean panels in Pasadena, we’re working on homes that sit under a municipal utility with its own rulebook, in a city with one of the strongest historic preservation programs in Southern California. That matters for how we approach a roof, how we document our work, and how we talk to homeowners about what their system actually needs.
Our Pasadena customers tend to be people who’ve already dealt with the big national outfits and didn’t love the experience. They want someone who answers the phone, shows up on time, and doesn’t try to upsell them on something they don’t need. That’s how we’ve built our reputation here. You’ll see Gus’s crew in uniform, background-checked, and we’ll tell you honestly if your panels don’t need cleaning yet. Sometimes the right answer is “your system is fine, call us in six months.”
Response time to Pasadena is usually same-day or next-day for cleaning calls. We coordinate scheduling from our Los Angeles office, but crews serve Pasadena locally, so we’re not driving from three counties away. The 90-Day Done Right Promise covers every cleaning job in writing. If something isn’t right, Gus comes back and makes it right. One phone call is all it takes.
Our Solar Panel Cleaning Services in Pasadena
Residential Panel Cleaning
A standard residential cleaning in Pasadena runs $150 to $325. We use deionized water and soft, non-abrasive brushes that won’t scratch the glass or void your panel warranty. Most homes in the 91104 Bungalow Heaven district and the 91107 ranch neighborhoods take under two hours from setup to final rinse. If your panels are accessible and the pitch is reasonable, we’re in and out the same morning.
Commercial Array Cleaning
For commercial arrays in Pasadena, pricing depends on total panel count and roof access, but most flat-roof commercial systems in the $400 to $900 range. We work around your business hours so we’re not interrupting foot traffic or blocking parking. If you manage a property in Pasadena with a rooftop array, call us for a walkthrough and we’ll give you a firm number before we start.
Bird & Critter Guard Installation
This is the big one in Pasadena, especially in the older neighborhoods. Pigeons nest under panels, and their droppings don’t just cut production, they corrode wiring and create hot spots that permanently damage cells. Critter guard installation in Pasadena typically runs $600 to $1,400 depending on the array perimeter. Our guards are powder-coated steel mesh that keeps birds out while allowing airflow, and they won’t affect your inverter warranty or PWP interconnection.
Debris & Soiling Removal
Between Santa Ana wind events and the sheer amount of tree cover in neighborhoods like San Marino-adjacent Pasadena, panels collect more than dust. We remove leaf buildup, pollen film, ash, and the fine grit that settles into panel frame corners. Standard debris removal is included with any residential cleaning, and we’ll point out anything that needs attention while we’re up there, like loose racking or damaged wire clips.
We also offer Solar Panel Cleaning as part of scheduled maintenance plans for customers who want to set it and forget it. If you live in Pasadena, we’ll set up a cadence based on your specific conditions, not a generic calendar.

Trusted Brands We Service in Pasadena
We clean and maintain panels from every major manufacturer you’re likely to have on your roof. That includes SunPower arrays, which we see constantly in Pasadena’s older housing stock, plus Tesla, Enphase, and SolarEdge systems. We work with your existing inverter and monitoring setup, and we know how PWP’s interconnection rules apply to each brand’s reporting requirements. If your monitoring app shows a production drop and you’re not sure whether it’s soiling or something else, we’ll diagnose it before we clean. No invented problems, no unnecessary add-ons.
Common Solar Panel Cleaning Problems We See in Pasadena Homes
Pasadena throws a specific set of problems at solar owners. Here’s what we run into most often:
- Ash and grit from Santa Ana wind events. When the winds kick up, ash from the mountains and fine particulate settle into panel frame corners and along the bottom edge. That grit traps moisture against the glass, which accelerates microcrack growth along cell edges over time. Annual or semi-annual cleaning removes it before it becomes a permanent efficiency loss.
- Baked-on bird droppings. With roughly 284 sunny days a year, droppings that would just wash away in a coastal climate bake onto the glass here. Left for weeks, they create hot spots that permanently degrade cell output. The Bungalow Heaven district is especially bad for this, the mature trees and older roof lines make perfect pigeon habitat.
- Hard-water mineral scale from sprinkler overspray. Pasadena’s municipal water is hard, and when sprinklers hit panels day after day, calcium and mineral deposits etch the glass. Every year that goes untreated, you’re losing 2 to 3 percent light transmittance. We remove existing scale and can recommend simple fixes to prevent future buildup.
- Leaf and pollen film in tree-heavy neighborhoods. The streets around Alhambra Road and the northern edges of 91103 have enough canopy that pollen and leaf litter form a sticky film on panel surfaces. It cuts production more than most owners realize, and it’s one of the easiest things to fix with a proper cleaning.

FAQs - Solar Panel Cleaning in Pasadena
PWP does not have a formal rule requiring cleaning receipts, but here’s what actually happens: during true-up statement reviews, if your production shows a significant unexplained drop, PWP has asked customers for maintenance documentation including cleaning records. Having a log of your scheduled cleanings, with before/after production data, makes those conversations a lot shorter. We provide that documentation as a standard part of every scheduled cleaning plan in Pasadena. If you’ve gotten a true-up notice you don’t understand, call (877) 550-6892 and we’ll walk you through what to gather.
Twice a year is the right cadence for most Bungalow Heaven homes. The combination of mature trees, established pigeon populations, and Santa Ana grit means panels in 91104 soil faster than in the newer, more open eastern ZIP codes. Some homeowners with heavy tree cover over their array get a third cleaning after the worst of the windy season. If you’re not sure, we’ll come out, take one look, and tell you honestly whether you need it now or can wait. No charge for the assessment.
Yes, and it’s not subtle. Coastal LA panels deal with marine layer haze and light dust. Pasadena panels deal with wind-driven grit, ash, and fine particulate that embeds itself in frame corners and along the lower glass edge. That material traps moisture and accelerates microcrack growth if it’s not removed. We use a slightly different process here: pre-rinse to float off abrasive particles before any brush contact, then deionized water so nothing re-deposits as the panels dry. The goal is removing what the wind put there without scratching the glass in the process.
No. Guard installation does not change your system’s electrical configuration, so PWP’s interconnection agreement is unaffected. And because the guards attach to the panel frames and racking, not to the panels themselves, they won’t void any inverter or panel warranty. We’ve installed guards on systems from SunPower, Enphase, and SolarEdge in Pasadena without a single warranty issue. We also document the installation with photos so you have a record if a manufacturer ever asks.
In the 91107 ZIP, where soiling is typically lighter than the older tree-heavy neighborhoods, the math is different. A two-visit annual plan at $130 to $250 per visit costs you $260 to $500 a year. If soiling is costing you 5 to 8 percent of production, a system producing 8,000 kWh annually recovers 400 to 640 kWh per year. At PWP’s current rates, that’s $100 to $190 in recovered value annually, so payback usually lands between 18 and 30 months. If your system is smaller or soiling is minimal, once a year might be enough. We’ll tell you what your panels actually need, not what makes us the most money.
We cleaned a 7.2 kW SunPower array on a 1912 Craftsman bungalow in the Bungalow Heaven district of 91104 recently. Heavy pigeon droppings had cut production by an estimated 11%. Using deionized water and soft brushes, we restored output to within 4% of the original production estimate, and the homeowner used our before/after production logs to support a PWP net metering true-up discrepancy. That’s the kind of situation where documentation pays for itself.
Here’s something most generic solar cleaning pages won’t tell you: Pasadena’s municipal utility, Pasadena Water and Power, requires its own interconnection and net metering approvals, and cleaning receipts are often requested as part of ongoing system verification during true-up statement reviews. No neighboring SCE-served city asks for that. If you own solar in Pasadena, you need a cleaning company that understands PWP’s process and gives you the paperwork to back it up. That’s us.
