Why Glendora Homeowners Choose Gus’s Solar
Plenty of solar companies send a salesperson to your door in Glendora, give you a number, and then hand the work to a subcontractor they’ve never met. That’s not how we operate. Gus Petrakis owns the company and puts his own name on every job. Our crew is background-checked, uniformed, and works directly for us, not through a third party. When homeowners in the Morgan Ranch and Gordon Highlands areas call us about an existing system acting up, we treat it the same as a brand-new install: show up, figure out the problem, and be straight about what it costs.
We’re not a call center. The phone at (877) 550-6892 rings to a live person 24/7. If you bring us a recent utility bill, Gus builds the estimate from your actual usage and current SCE export rates, not from a generic brochure figure. He’ll tell you to take two weeks, think it over. The price stays the same. If a salesman needs an answer tonight, the answer should be no.
Solar Services We Offer in Glendora

Solar Battery Storage & Backup

Solar Panel Cleaning
Santa Ana winds push dust and ash onto panels across Glendora, and a dirty array can lose 10 to 15 percent of its output. We offer Glendora Solar Panel Cleaning with deionized water and soft brushes, no harsh chemicals, and we inspect the racking while we’re up there.

EV Charger Installation
If you’ve got an electric car in the garage, we can handle EV Charger Installation - Glendora on its own dedicated circuit with a permit pulled through Glendora’s building department. We’ll size the charger to work alongside your solar system without overloading your panel.
Solar Panel Maintenance & Monitoring
We keep an eye on system performance so a failing microinverter or a string that’s underperforming doesn’t sit unnoticed for months. Gus monitors systems personally, and if something goes wrong, he’s the one who calls you, not the other way around.
Solar Panel Repair
Whether it’s a cracked panel, a chewed wire, or an inverter that’s throwing error codes, we diagnose it and give you a straight answer: repair or replace, and what each one costs. We offer $40 off any repair over $200 and a free second opinion on any written estimate from another company.
Commercial Solar Installation
For Glendora businesses on Grand Avenue or Route 66, we design commercial arrays that cut operating costs without shutting down your operation. We handle engineering, permitting, and SCE interconnection for flat roofs and carports alike.

Why Glendora’s Climate & Housing Affect Solar
Glendora sits right where the San Gabriel Valley starts climbing into the San Gabriels, and that geography shapes almost every solar job we do here. The inland foothill location gets some of the strongest solar irradiance in LA County: minimal coastal fog, very few marine-layer mornings, and long, clear summer afternoons. That means a properly sized Glendora system produces more per panel than the same array in a beach city. But the mountain-backed terrain also funnels Santa Ana wind events through the canyons, so racking torque specs and wind-load calculations matter more here than they do five miles south. We don’t shortcut that part.
The housing stock splits into two distinct jobsites. South of Foothill, in the 91740 ZIP, you’ll find post-WWII and 1960s-70s ranch tract homes with straightforward gable roofs, easy attic access, and predictable framing. Those are the quickest installs in Glendora. Up north in 91741, the homes are larger, newer, and architecturally varied, with multi-plane rooflines that require real shading analysis and often cost more in labor because every penetration has to be flashed across a valley or a hip. That’s not padding. That’s just what the roof demands.

FAQs About Solar in Glendora
Most residential installs in Glendora take two to four days on the roof, plus two to four weeks for permit review and SCE interconnection approval. Hillside homes in the fire hazard zone usually add a week or two for fire-code plan checks. Call (877) 550-6892 and we’ll give you a realistic timeline for your specific address.
It depends on where you live. If you’re in the 91741 hillside neighborhoods inside the Very High Fire Hazard Severity Zone, we strongly recommend pairing solar with battery storage because SCE Public Safety Power Shutoffs hit those areas first and last longest. South of Foothill in 91740, outages are less frequent, but a battery still protects you from rate spikes in the evening. We’ll tell you straight what makes sense for your bill and your neighborhood.
Panel pricing in Glendora is in line with the rest of the San Gabriel Valley, typically $16,000 to $28,000 for a standard ranch home. The variable is hillside work in 91741, where fire-code ember-intrusion requirements and complex rooflines add labor cost you wouldn’t see in flatland cities. You can read exact line-item ranges in our pricing section above, or call (877) 550-6892 for a quote built from your real usage.
In most cases, yes. We keep same-day response open for service calls across Glendora and the surrounding foothill communities, and there’s no trip charge inside our own county. Call (877) 550-6892 and a live person answers, day or night, no voicemail and no ticket number.
For a single cracked panel or a failed microinverter, repair is almost always cheaper, usually $200 to $900 with the diagnosis included. Replacement only makes sense when multiple panels are underperforming or the array is over 20 years old and the manufacturer warranty has expired. We’ll show you the numbers either way, and we offer a free second opinion on any written estimate from another company, plus $40 off any repair over $200.

What Glendora Customers Say
"The install itself was excellent and the system performs as modelled. Permitting and the utility interconnection took about four months, most of it out of his hands, though the waiting was still frustrating."
- Marguerite Ostrowski"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
