Why Terrell Homeowners Choose Gus’s Solar
Terrell sits in a strange spot in the solar market. You’ve got door-knockers working the newer subdivisions off I-20, out-of-state outfits cold-calling the historic core, and homeowners who’ve been burned by a quote that looked different at the kitchen table than it did in the contract. Gus Petrakis started this company in 2011 to be the alternative to all that. His name, his address, and his license number are published. He’s the one who picks up the phone. And when you call with a question about your system two years after install, you’re not re-entering a customer-service queue and hoping for the best.
We’ve done work on homes near Griffith Park, out past the middle school, and in the newer sections around the Terrell Municipal Airport. The reviews we hear most from Terrell customers come down to the same thing: the quote matched the bill, the crew showed up when they said they would, and when one homeowner had a question about her inverter nine months after install, Gus picked up on the second ring and walked her through it in five minutes.
The 90-Day Done Right Promise is in writing on every job. If it’s not right, Gus makes it right. No arbitration clause. No fine print. One call brings him back.
Solar Services We Offer in Terrell
Solar Panel Installation
We design and install roof-mounted and ground-mount systems. On Terrell’s larger lots, ground-mounts often make more sense than roof work, especially where rooflines weren’t oriented for southern exposure. Every install uses equipment from Qcells, REC, SunPower, or Panasonic, and Gus’s own crew does the roof work, including every penetration flashed properly.

Solar Battery Storage & Backup
With Oncor’s avoided-cost buyback paying roughly 3 to 5 cents per kilowatt-hour, sending surplus power back to the grid is a losing math problem for Terrell homeowners. Terrell Solar Battery Storage & Backup changes that equation: you keep what you generate and use it at night or during an outage. We install Enphase and FranklinWH systems sized to your actual usage.
Learn more about our Solar Battery Storage & Backup in Terrell.

Solar Panel Cleaning
Terrell gets about 40 inches of rain a year, but that rain doesn’t rinse off the fine dust and pollen that settles between storms. A film of grime can shave 5 to 10 percent off production. We offer Terrell Solar Panel Cleaning safely and check connections while we’re up there.

EV Charger Installation
More Terrell households are adding an EV or plug-in hybrid to the driveway, and a Level 2 charger fed by your solar array means you’re fueling off sunlight instead of the grid. We handle the panel assessment, wiring, and EV Charger Installation in Terrell in one visit.

Solar Panel Maintenance & Monitoring
We don’t install a system and disappear. Gus monitors production remotely and calls you when output drops. If a panel is underperforming or a microinverter fails, you’ll know about it from us before you notice it on your bill.

Solar Panel Repair
Hail damage, storm debris, failed microinverters, aging wiring: we fix all of it. If a national outfit installed your system and won’t return your calls, we’ll take a look. A second opinion on any written estimate is free.

Commercial Solar Installation
For Terrell businesses along State Highway 34 and around the downtown core, commercial solar can cut operating costs meaningfully. We design systems for warehouses, retail, and agricultural operations with the same straight numbers we give homeowners.

Why Terrell’s Climate & Housing Affect Solar
Terrell sits in that transition zone between the drier Dallas-Fort Worth core and the humidity of East Texas. You get roughly 40 inches of rain a year and a bit more cloud cover than western Metroplex cities, which means production estimates pulled from generic online calculators calibrated to Dallas can run a little optimistic. The honest number matters, and we build quotes off your real utility bill, not a brochure model.
More pressing is the hail. This part of Kaufman County sits in a well-documented hail corridor where one- to two-inch stones are a regular seasonal event. That’s why we lean toward panels with strong IEC 61215 hail-resistance ratings. It’s not a sales talking point here. It’s the difference between a system that shrugs off spring storms and one that files an insurance claim every other year. And this matters on Terrell homes specifically: the historic core has a lot of early- and mid-20th-century wood-frame construction with aging roof decks. We’ll tell you honestly if the decking needs replacement before we mount anything. The newer tract homes on larger lots usually have sound decks, but their rooflines were designed for curb appeal, not southern solar exposure. That’s where ground-mounts come in.
Pricing for Solar in Terrell
Here’s the honest range, based on what we actually see in 75160 and 75161:
- Roof-mounted solar installation: $15,000-$35,000 before the federal tax credit, depending on system size and roof condition.
- Ground-mount solar installation: $22,000-$45,000, reflecting trenching, racking, and site work.
- Battery storage (one battery): $9,000-$14,000 installed, before incentives.
- Solar panel cleaning: $150-$350 for a standard residential array.
- Panel or inverter repair: $200-$900 depending on the fault. We offer $40 off any repair over $200.
- EV charger installation: $800-$2,200 depending on panel capacity and run length.
Bring us a bill. Gus will give you the year-25 output number, not the day-one brochure figure. And take two weeks to think about it. The price will be the same.

FAQs About Solar in Terrell
Yes, but the math changes. Oncor serves Terrell under Texas’s deregulated market and pays avoided cost, roughly 3 to 5 cents per kilowatt-hour, for surplus power you export. That’s far below the retail rate you pay to import electricity. The honest play in Terrell is a system paired with battery storage that optimizes self-consumption: generate during the day, store what you don’t use, and draw from the battery at night. Oversized export-heavy arrays built for retail net metering don’t pay off here. Call (877) 550-6892 and we’ll run your actual bill through the real numbers.
Most Terrell residential roof-mounted systems run $15,000 to $35,000 before the federal tax credit. Ground-mounts on larger Kaufman County lots typically run $22,000 to $45,000. Battery storage adds $9,000 to $14,000 per battery installed. The exact figure depends on your roof condition, system size, and whether you’re adding storage. Estimates are free, and the number we quote is the number you pay. Call (877) 550-6892 for an exact quote.
If the system is under ten years old and the issue is a failed microinverter, damaged panel, or wiring fault, repair usually makes sense and costs $200 to $900. If the system is older, underperforming, or was poorly installed by an out-of-state outfit, replacement may be the better long-term call. We’ll give you a straight answer either way, and a free second opinion on any written estimate.
For emergencies, yes. We keep same-day response across the Terrell area, including the 75160 and 75161 ZIP codes. For scheduled installations and cleanings, we’re typically out within a day or two. A live person answers the phone 24/7. If it’s urgent, call (877) 550-6892 and we’ll be there.
Yes. The senior and veteran discount is 10 percent off and it never expires. It applies to installation, repair, cleaning, and battery work. We don’t advertise it with an expiration date because there isn’t one.

What Terrell Customers Say
"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."
- Ferdinand Kaltenbrunner"Four different companies knocked on my door in one summer and every one of them wanted a signature that evening. Gus has a shop with his name on it, gave me the numbers on paper, and told me to take a fortnight and think about it."
- Winifred Castellano"Honest quoting and good workmanship. He is not the cheapest quote I got, by some way, and he told me that himself and explained what the difference bought. I chose him anyway and I am glad."
- Alistair Fennimore
