If you live in Rowland Heights and your SCE bill keeps climbing every summer, you’re not alone. Homes out here sit inland, past the marine layer, so your roof gets hit with real sun from June through October. A properly sized system in the 91748 typically offsets 85-100% of annual usage. We quote off your actual bill, not a brochure, and Gus Petrakis puts his name on every job. Call (877) 550-6892 and you’ll get a straight answer on whether solar makes sense for your specific roof.

Why Rowland Heights Homeowners Choose Gus’s Solar
Gus’s Solar is the locally owned, owner-operated alternative to the door-knockers working the San Gabriel Valley. Gus Petrakis founded the company in 2011, publishes his name and license number, and answers his own phone. When you call, a live person picks up. Not a voicemail, not a ticketing portal, not a call center three states away. That matters when your inverter throws an error at 9 p.m. and you want to know whether to shut anything off.
We serve Rowland Heights week in and week out. Homeowners in the Ridgemoor and Vantage Pointe neighborhoods have had us on their roofs for everything from full installs to panel cleaning after Santa Ana wind events. The team is background-checked and uniformed, and Gus’s own crew does the install. No subs, no hand-offs. The 90-Day Done Right Promise covers every job in writing: if it’s not right, Gus makes it right, and one call brings him back.
Solar Services We Offer in Rowland Heights
Solar Panel Installation
We design and install roof-mounted systems sized to your actual SCE usage, not a generic square-footage estimate. Rowland Heights homes built between the mid-80s and late 90s almost always have concrete tile roofs, which means tile-hook mounting hardware and careful flashing work, not standard rail systems.

Solar Battery Storage & Backup
Battery backup gives you power when SCE’s public safety shutoffs or summer grid strain hits the 91748. We install FranklinWH and Tesla Powerwall systems that pair with your panels and keep your refrigerator, lights, and Wi-Fi running.

Solar Panel Cleaning
Dust, ash, and bird droppings cut into production more than most people realize. After a few dry months, a film builds up that can shave 5-15% off your output.

EV Charger Installation
If you’ve got an electric car in the driveway, a Level 2 charger beats the 120-volt trickle charge every time. We run the circuit, mount the charger, and make sure your panel has the headroom for it.
Solar Panel Maintenance & Monitoring
Gus monitors systems after install and is the one who calls you when something looks off. Inverter underperforming, a string dropping voltage, a panel throwing a fault. You’ll hear from us, not from an automated email.
Solar Panel Repair
Micro-cracks, failed optimizers, chewed wiring from roof rats that love Rowland Heights attics. If your system came from a company that went dark, we’ll diagnose it and fix it for a fair price.
Commercial Solar Installation
Rowland Heights has a lot of small commercial buildings along Colima Road, Nogales Street, and Fullerton Road. We design commercial arrays for retail, office, and warehouse rooftops, with the same straightforward pricing we give homeowners.
Neighborhoods We Serve in Rowland Heights

Why Rowland Heights’s Climate & Housing Affect Solar
Rowland Heights is unincorporated Los Angeles County, so every solar permit routes through LA County Building and Safety, not a city hall. If you’ve ever tried to pull a permit in neighboring Walnut or Diamond Bar, you know they have their own departments. Out here, it’s LACBS, which means county-specific plan-check checklists and inspection scheduling through the ePermits portal. An installer who mostly works incorporated cities in the valley can lose a week just trying to get the paperwork accepted. We’ve been through this process enough times to know exactly how the county checkers want drawings formatted and where the common rejection points are.
Then there’s the housing stock. Rowland Heights was built out mostly between the mid-1980s and late 1990s as LA County tract housing. Nearly every residential roof we work on is concrete S-tile or low-profile flat tile. That’s not the cheap composition shingle roof a national crew can throw standard flashed rails on. Concrete tile requires tile-hook or Comp-Out mounting systems, and the underlayment beneath those tiles is now 25 to 40 years old. If it’s cracked when we lift the tiles, we account for that before we put anything down. A crew that treats your roof like a shingle roof in Ohio is going to create leaks you won’t discover until winter rain. Gus’s crew knows Rowland Heights tile roofs because that’s most of what we work on.
Sitting inland at the base of the Puente Hills also means different sun math. Rowland Heights gets roughly 5.5 to 5.8 peak sun hours per day, consistently, which is better than coastal cities fighting the marine layer. But hillside homes north of Colima Road backing up to the hills can have late-afternoon shading from the ridgeline. Flat-valley assessments miss that. We do an on-site shading analysis before we design anything, because a 12-panel system that produces 4 hours of clean sun on a hillside lot is not the same as one that catches all 5.8.
Pricing for Solar in Rowland Heights
Here’s what you’re actually looking at, based on systems we’ve installed in Rowland Heights.

Bring me a bill, I’ll bring you the math. That’s how Gus quotes every job. Your actual usage and your actual SCE rate plan drive the numbers, not a brochure figure. And take two weeks. Think about it. The price will be the same.

FAQs About Solar in Rowland Heights
Most residential installs in the 91748 take 2 to 4 days on the roof, but the full process from signed contract to permission-to-operate runs 6 to 10 weeks because permits go through LA County Building and Safety rather than a city department. Call (877) 550-6892 and we’ll give you a realistic timeline for your specific project.
Almost always yes. Rowland Heights gets strong, consistent sun at 5.5 to 5.8 peak hours a day, and SCE rates have climbed steadily for years. Most systems we install in the 91748 pay for themselves in 6 to 9 years and then produce for another 15 to 20. The math works off your actual bill, not a salesman’s assumptions.
Yes, and that’s most of what we do in Rowland Heights. Concrete S-tile and flat-tile roofs from the 80s and 90s need tile-hook or Comp-Out mounting rather than standard flashed rails. We’ve installed on hundreds of these roofs and we replace any tile we break. Call (877) 550-6892 for a free estimate and we’ll assess your roof condition on site.
We handle the entire LACBS process, from plan-check submission to final inspection. County checkers have their own Title 24 and NEC interpretation quirks, and we know what they’ll flag before they flag it. You won’t be asked to call the county or chase down an inspector.
We monitor your system and call you when something looks off. If it’s not right within the first 90 days, the Done Right Promise means Gus comes back and fixes it, in writing. After that, one call to (877) 550-6892 gets a real person and a service appointment, usually same-day or next-business-day.

What Rowland Heights Customers Say
"He modelled it on my actual bill and the current export rates rather than the old ones, and told me plainly that the payback was longer than the door knockers had claimed. Then it came in about where he said it would."
- Octavius Redmond"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."
- Sunita Balakrishnan"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."
