AfterSolar Services in Fullerton, CA
Solar in Fullerton is a two-utility town. Depending on your address, you’re served by either Fullerton Public Utilities or Southern California Edison, and that single detail changes your interconnection paperwork, your inspection timeline, and the real numbers on your return on investment. Gus’s Solar handles both utilities every week. We know which map to check before we ever park the truck, and we’ll tell you the year-25 math off your actual bill, not a brochure. Call us at (877) 550-6892 and we’ll be out to your place, usually same week.

Why Fullerton Homeowners Choose Gus’s Solar
When a solar contractor has to ask which utility serves your house, that’s a bad sign. We’ve seen out-of-area companies file an SCE interconnection application for a property that sits in FPU territory, and the homeowner loses weeks waiting on a correction. Gus Petrakis put his name on this company in 2011, and the way we work in Fullerton hasn’t changed since: bring us a bill, we’ll bring you the math.
We’ve done installs and repairs in the historic district around downtown (the 92832 ZIP), through the ranch-house neighborhoods along Bastanchury and Rolling Hills in north Fullerton, and up in the Coyote Hills corridor where custom homes sit on steeper lots. Homeowners keep calling us back because the crew that shows up is background-checked, uniformed, and works for Gus directly. No subcontractors, no crew nobody’s ever met. The 90-Day Done Right Promise is in writing on every job: if it’s not right, one call brings Gus back. And when you call us at (877) 550-6892, a live person answers, even at 2 a.m.
Solar Services We Offer in Fullerton
Solar Panel Installation
A new system for a Fullerton ranch house or a Craftsman in the 92832 historic core starts with the right roof assessment, not a sales pitch. Gus quotes the year-25 output, not the day-one brochure number, so you know what your system actually produces as it ages, not what it says on the box.

Solar Battery Storage & Backup
Power outages don’t care which utility you’re on, and Fullerton homeowners are adding battery backup whether they’re on FPU or SCE. We install FranklinWH and Tesla systems sized to your actual usage, so your fridge, medical devices, and lights stay running when the grid doesn’t.

Solar Panel Cleaning
Fullerton sits far enough inland that you don’t get the marine layer scrubbing your panels like they would in Seal Beach, but you do get dust, pollen, and the occasional Santa Ana wind coating. Dirty panels lose output, and we’ll get yours back to full production with a proper cleaning, not a garden hose from the ground.
Learn more about our Solar Panel Cleaning in Fullerton.
EV Charger Installation
Charging an EV at home is the cheapest fuel in Fullerton, especially with solar on the roof. We route the circuit, mount the charger, and make sure your panel has the capacity to handle the load, all done by Gus’s own crew with a permit when the city requires one.
Fullerton homeowners can call us at (877) 550-6892 for a free estimate on an EV charger install.
Solar Panel Maintenance & Monitoring
Systems don’t run themselves forever. We monitor production, inspect connections, and catch small problems before they become expensive ones. If your system was installed by a company that disappeared, we’ll take it over and get it performing again.
Call (877) 550-6892 and we’ll schedule a checkup for your Fullerton system.
Solar Panel Repair
Cracked glass, bad inverter, chewed wiring, underperforming array. Gus’s crew diagnoses the problem, gives you an honest price before any work starts, and doesn’t ask you to sign for a whole new system when a repair is the right call.
We offer a free second opinion on any written estimate, and seniors and veterans get 10% off, permanently.
Commercial Solar Installation
Fullerton’s commercial corridors along Commonwealth Avenue and Harbor Boulevard have flat rooftops that are ideal for solar. We work with business owners to size systems that actually reduce the electric bill, with the same no-pressure, upfront pricing we give homeowners.
Call (877) 550-6892 and bring us your bill. We’ll bring you the math.

Why Fullerton’s Climate & Housing Affect Solar
Fullerton’s solar math is better than most of Orange County because the city sits far enough inland to escape the marine layer that suppresses sun hours along the coast. You get noticeably more peak sun hours than Huntington Beach or Seal Beach, which means more production from every panel. But that inland position also means hotter summer afternoons, often 10 to 15 degrees above the coast, and panel efficiency drops slightly in high heat. Proper ventilation gap installation under the panels matters more here than it does somewhere cooler and breezier.
Then there’s the housing stock. The 1920s and 1930s Craftsman bungalows and Spanish Colonials around downtown Fullerton often have complex rooflines, smaller usable roof planes, and sometimes multiple layers of reroofing over the original wood sheathing. That complicates racking attachment and structural load assessments. Meanwhile, the 1950s and 1960s ranch-style tracts across central Fullerton have simpler roofs but older electrical panels that sometimes need upgrading before a system can pass inspection. Gus’s crew has dealt with every one of these conditions, and we’ll tell you what’s actually involved at your address before you commit to anything.
Pricing for Solar in Fullerton
Here’s the honest version. A solar panel installation in Fullerton typically runs between $14,000 and $32,000 before the federal tax credit, depending on system size, roof complexity, and whether you add battery storage. A battery backup system like FranklinWH or Tesla Powerwall adds roughly $9,000 to $16,000 per unit before tax credits. Solar panel cleaning runs $150 to $350 for a standard residential array. Repairs vary widely, but most inverter replacements fall between $1,200 and $3,200, and we offer $40 off any repair over $200.

FAQs About Solar in Fullerton
Check your electric bill. If it says Fullerton Public Utilities, you’re on the city’s municipal electric system. If it says Southern California Edison, you’re on SCE. Most of the older downtown core in 92832 and parts of 92833 are FPU, while much of the rest of the city falls under SCE. If you’re not sure, call us at (877) 550-6892 with your address and we’ll check the utility map before any site visit, because filing the wrong interconnection application resets your timeline by weeks.
Not for our customers. The installation cost is the same either way. What changes is the paperwork route and the net metering structure, which affects your payback timeline, not the cost of the hardware. We quote interconnection costs upfront and handle the full application for whichever utility serves your address. Call (877) 550-6892 and we’ll walk you through the exact numbers for your home.
Most of the time, yes, but the roof matters. Pre-war Craftsman bungalows and Spanish Colonials in the historic district often have smaller usable roof planes and complex rooflines, so the system may need to be laid out differently than on a 1960s ranch house. We check the roof structure, the sheathing condition, and the panel capacity before we quote, so there are no surprises on install day.
For urgent repairs, we do everything we can to get a crew out the same day. For new installations and quotes, we’re typically at your house within the same week. A live person answers our phone 24/7, so call (877) 550-6892 right now and we’ll tell you exactly when we can be there.
Yes. Seniors and veterans get 10% off, and that discount never expires. We also offer a free second opinion on any written estimate, and there’s no trip charge for Fullerton addresses. That’s the L.O.C.A.L. way: Local roots, On time, Community first, Accountable, Loyal.

What Fullerton Customers Say
"Told me straight that a battery did not make sense for how we use power and sold me the array without it. He talked himself out of a good deal of money that afternoon."
- Reginald Pontefract"He flashed every roof penetration properly and showed me the flashing before it went down. Three roof seasons on and not a drop anywhere."
- Philomena Achara"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."
- Cassius Delacroix
