Fast, Reliable Solar Panel Installation Across Pasadena
Solar panel installation in Pasadena runs $14,500 to $28,000 before incentives for a typical 5 to 8 kW rooftop system, and because Pasadena Water and Power runs its own interconnection queue separate from SCE, the timeline from signed contract to Permission to Operate usually takes 6 to 12 weeks. That second part trips up a lot of installers. Gus’s Solar has walked enough Pasadena jobs through PWP’s process that we quote realistic in-service dates, not optimistic ones built on neighboring utility timelines. Call (877) 550-6892 and we’ll look at your actual bill, your roof, and your panel before we tell you what it’ll cost.
We come out to Pasadena properties from Altadena to East Pasadena, from the Craftsman streets of Bungalow Heaven to the mid-century ranches of 91107. Gus Petrakis started this company in 2011 and still answers his own phone. Bring us a bill, we’ll bring you the math.
Why Gus’s Solar Is Pasadena’s Preferred Solar Panel Installation Company
Most Pasadena homeowners we sit down with have already talked to two or three other companies. What they tell us is the same story: a door-knocker quoted one number, the “closer” quoted another, and nobody mentioned PWP or the Design Review Board until after they’d signed. That’s not how we work. Gus quotes the year-25 output, not the day-one brochure number, and he tells every customer the same thing: take two weeks. Think about it. The price will be the same.
We’ve installed systems throughout Pasadena, and our customers tend to hear about us from neighbors on the same block, not from a Facebook ad. That’s the kind of reputation you build over 29 years of showing up on time and putting your own name on the work. The 90-Day Done Right Promise is in writing on every job: if it’s not right, one call brings Gus back. Not a ticket. Not a portal. Gus.
When you call us about Solar Panel Installation, a live person picks up 24/7. Not a voicemail, not a call center in another state. And if you’re in Pasadena, our crew can usually be at your door for an estimate within a day or two. The background-checked, uniformed team that shows up is Gus’s own crew. We don’t hand your roof off to a sub.
Our Solar Panel Installation Services in Pasadena
Rooftop Solar Installation
We design and install rooftop arrays sized to your actual Pasadena usage, not a generic square-footage formula. Pasadena’s older housing stock means we’re often working with original 2×4 rafters or mid-century trusses that need a structural look before panels go up. On a typical Pasadena home we’ll install 12 to 22 panels depending on your bill, your roof planes, and what PWP will approve for backfeed.

Solar System Design & Permitting
Design and permitting in Pasadena is a two-track process most installers don’t mention until it stalls. There’s the City of Pasadena building permit, and then there’s the PWP interconnection application, which runs on its own calendar and its own engineering review. We handle both, and we’ve learned PWP’s queue well enough to quote you an honest in-service date. For homes in the 91104 historic districts, we also prepare the Design Review Board submittal and adjust panel placement to keep arrays out of street view where the guidelines require it.

Solar Panel Replacement
If you’ve got an aging array from an installer who’s no longer in business (a story we hear often around Pasadena), we’ll assess what’s salvageable and what isn’t. Sometimes a few failed panels on an otherwise fine string just need matching replacements. Sometimes the whole array needs re-racking because it wasn’t torqued for Santa Ana gusts. We’ll tell you the truth either way, and we’ll give you a free second opinion on any written estimate you’ve already received.

Roof-Mount & Tile Roof Solar
Tile roofs are common throughout Pasadena’s Spanish Colonial Revival homes, especially in the 91103 and 91105 neighborhoods. We use tile-replacement mounts rather than drilling through brittle clay tile, which means fewer broken tiles and a cleaner finished look. Your flashings get sealed properly the first time, because a Pasadena roof that leaks after a solar install is a call we never want you to make.

Trusted Brands We Service in Pasadena
Gus’s Solar installs equipment from manufacturers we’d put on our own homes: Qcells, REC, SunPower, and Panasonic, with monitoring and inverters from Enphase and SolarEdge. For Pasadena’s sunny, wind-exposed conditions, we lean toward REC Alpha Pure-R and Qcells panels paired with Enphase IQ8 microinverters, which handle partial shading from mature trees better than string setups. If something fails, we stock common replacement parts locally and our crews are already in your neighborhood, not three counties away.
Common Solar Panel Installation Problems We See in Pasadena Homes
- PWP rejects the interconnection application over panel capacity. The 100A electrical panels on many 1950s and 1960s ranches in 91107 can’t handle the inverter backfeed PWP requires. A 200A service upgrade usually fixes it, but it adds cost and time you should know about before you sign anything.
- Design Review Board denial on street-visible panels. Bungalow Heaven and other historic districts in 91104 require Design Review approval for panels visible from the street on contributing structures. We re-route arrays to rear roof planes or re-design with a higher-pitch hidden placement so you’re not fighting the board.
- Santa Ana wind damage to under-built racking. Gusts channeled through the San Gabriel mountain canyons can torque panels on poorly racked roofs, leading to microcracked cells and premature inverter faults years before their time. We spec racking and torque values for wind loads most inland installers never account for.
- Leaks from sloppy tile-roof penetrations. Spanish tile and clay tile roofs across Pasadena are unforgiving. Drill through them wrong and you’ll chase leaks for years. We use tile-replacement mounts and proper flashing, and Gus’s crew does the work, so the buck stops with us.

FAQs - Solar Panel Installation in Pasadena
PWP is a city-owned municipal utility with its own net metering agreement, its own engineering review standards, and its own queue. You cannot use an SCE interconnection application in Pasadena. Expect the PWP process to add roughly 2 to 6 weeks beyond what an SCE-based timeline would show, and an installer who quotes you an SCE schedule is going to miss your in-service date. Call (877) 550-6892 and we’ll tell you what PWP’s queue looks like right now.
Yes, if your home is a contributing structure in the Bungalow Heaven historic district and the panels are visible from the street, you’ll need Design Review Board approval. We handle that submittal for you and we often re-position arrays to rear roof planes or higher-pitch hidden placements to make approval cleaner. It adds time, but not nearly as much as a denial does.
Most likely not on a grid-tied system. PWP’s interconnection rules cap the inverter backfeed your panel can handle, and a 100A panel almost always falls short for anything beyond a very small system. You’re looking at a 200A service upgrade, which runs $3,500 to $5,500 in Pasadena. We’ll tell you up front if you need it, not after you’ve signed the contract.
Santa Ana gusts through the San Gabriel canyons can hit 60 mph or more in exposed Pasadena locations. Under-torqued racking on a cheap install will loosen, panels will flex, and you’ll get microcracked cells and inverter faults years early. We spec racking and torque values for wind load, and we pick panel brands like REC and Qcells that hold up under repeated thermal and wind cycling. It costs a little more up front and saves you a re-rack later.
You will. Pasadena sits inland at the base of the San Gabriels, so we escape the June Gloom and marine layer that suppress coastal yields. Pasadena averages roughly 284 sunny days per year, and a system here will produce meaningfully more kWh per installed watt than the same system in Santa Monica. That’s why we size your array off your actual PWP bill and Pasadena’s irradiance data, not a generic California average.
