AfterFast, Reliable Solar Panel Installation Across Ennis
Solar panel installation in Ennis runs $18,500 to $34,000 for a typical 7 to 11 kW rooftop system on the single-story ranch homes that dominate this town. That number includes the panel upgrade most older Ennis houses need before Oncor will sign off on interconnection. We’re on the ground in Ennis every week, and we answer the phone at (877) 550-6892 when you call, day or night.
Most Ennis homeowners we meet have already sat through a high-pressure pitch from an out-of-state solar company. They’ve been quoted one number over the phone and a different number at the kitchen table. We don’t work that way. Gus Petrakis puts his name on the truck, quotes off your actual utility bill, and tells you to take two weeks before you sign anything. The price will be the same.
Why Gus’s Solar Is Ennis’s Preferred Solar Panel Installation Company
We’re not a pop-up sales crew that blew in after the last hailstorm. Gus’s Solar has been locally owned since 2011, and Gus himself answers his own phone. People in Ennis see our trucks on I-45, on Ennis Avenue, and in the Brookshire’s parking lot. They know who we are because we keep showing up, year after year.
The 90-Day Done Right Promise matters here. Every solar job in Ennis gets it in writing: if it’s not done right, Gus makes it right. One call brings him back. That’s not a marketing line. That’s the standard we’ve operated under for 29 years of serving local communities.
Our crew knows the difference between a 1950s ranch off West Knox Street and a newer build near the Ennis Country Club. That matters when you’re walking a roof and reading the trusses. It matters when the city permit office wants specific documentation. And it matters when we’re sizing a system around the old 100-amp service that still feeds half the homes inside ZIP 75119.
We serve Ennis directly, with scheduling coordinated from our Dallas-Fort Worth office and crews on the ground here regularly. Response time for a standard site visit is typically two to three business days. Emergency calls after a storm get priority.
Our Solar Panel Installation Services in Ennis
We handle the full Solar Panel Installation process, but three jobs come up again and again in Ennis specifically. Here’s how we approach them.
Rooftop Solar Installation
Most Ennis roofs are simple ranch-style slopes with good southern or western exposure. That’s the good news. The work we put into flashing every roof penetration properly is the difference between a system that lasts 25 years and one that leaks after the first hard spring storm. Gus’s own crew does every install. No subs. You know who’s on your roof before they get there, and they’re background-checked and uniformed.
Solar System Design & Permitting
Ennis sits in Ellis County, which means we’re working with the city’s permit office and Oncor for interconnection. We’ve done this enough to know what gets flagged. Older homes with original 100-amp panels almost always trigger an upgrade requirement. We flag that at the quote stage, not the permit stage. You’ll see the full cost on day one, not after the city kicks the application back.
Solar Panel Replacement
Hail happens here. If your existing panels are five or ten years old and didn’t carry a Class 4 impact rating, they may already be microcracked from repeated strikes. We’ll inspect, test, and give you a straight answer on whether replacement makes sense or whether you should ride them out. We carry Qcells, REC, and SunPower stock for Ennis customers.
Roof-Mount & Tile Roof Solar
Most Ennis roofs are composition shingle, but a few older homes near the historic downtown have tile or Spanish-style elements. Mounting on tile requires different flashings and a slower hand. We’ve done enough of them around Ennis that this isn’t a learning curve. It’s just part of the job.

Trusted Brands We Service in Ennis
We work with panels and equipment from Qcells, REC, and SunPower. For Ennis specifically, we recommend panels with Class 4 impact ratings first. The hail here isn’t theoretical. We also install Enphase microinverters and Tesla Powerwall battery backups for homeowners who want storage. If you bring us a bill, we’ll bring you the math on any brand you’re considering, and we’ll quote the year-25 output, not the day-one brochure number.
Common Solar Panel Installation Problems We See in Ennis Homes
- 100-amp service panels blocking interconnection. Oncor won’t approve a net metering application when the home’s main breaker can’t handle the added load from an inverter. Homes built before 1990 in Ennis commonly run original 100-amp panels. We bundle the service upgrade into the quote so there’s no surprise.
- Hail damage to non-Class 4 panels. The same storm tracks that push Ennis insurers to mandate Class 4 roofing also batter solar panels. Panels without impact ratings degrade faster here. We spec Class 4 from the start.
- Blackland gumbo clay shifting ground-mount racks. If a ground-mount system is anchored like we’re in sandy loam, Ellis County’s expansive clay will heave and shift it within a season or two. Footings here need to go deeper and wider than standard spec.
- Roof penetrations failing after the first storm season. We’ve been called to fix other installers’ work around Ennis. Poor flashing around roof penetrations is the most common failure we repair. Spring winds and heavy rain will find every mistake.
Pricing for Solar Panel Installation in Ennis, TX
Here are the actual ranges we quote in Ennis at the start of 2026. A 7 kW rooftop system on a single-story ranch runs $18,500 to $24,000 before incentives. A 9 to 11 kW system with panel upgrade included runs $26,500 to $34,000. A 200-amp main panel upgrade, when required, adds $3,200 to $4,800. Ground-mount systems on blackland clay run $2,000 to $4,500 more than comparable rooftop installs because of the deeper footings required. The federal tax credit still covers 30% of the total system cost for most homeowners. Senior and veteran customers get a 10% discount that never expires. Bring me a bill and I’ll bring you the math.

FAQs - Solar Panel Installation in Ennis
If your home was built before 1990 and still has the original 100-amp panel, the answer is usually yes. Oncor won’t approve your interconnection application until the main breaker is sized for the added inverter load. We caught this early on a 1970s ranch near Ennis’s historic downtown. The homeowner’s original panel was maxed out before we could even file for interconnection. We coordinated a 200-amp service upgrade, then installed REC Alpha Pure panels with Enphase microinverters. The city’s permit office flagged the panel upgrade before approving our net metering application, so bundling the electrical work from day one saved the homeowner a two-week delay. Call (877) 550-6892 and we’ll check your panel before you commit to anything.
Ennis sits on a storm corridor that produces frequent large-hail events tracking northeast toward Dallas. Local insurers already mandate Class 4 impact-rated roofing across the area because of this pattern. That same logic applies to your solar panels. Standard panels without Class 4 ratings will get battered, microcracked, and degraded years before their warranty would suggest. In Ennis, Class 4 panels aren’t an upsell. They’re what keeps your system producing through the first decade. If a salesman is pushing a cheaper panel without an impact rating, ask him how many Ennis roofs he’s paid to repair.
Ellis County’s blackland gumbo clay expands and contracts dramatically with moisture changes. Standard footing specs written for sandy or loam soils will fail here within one or two seasons. We spec ground-mount footings at least 30% deeper and wider than manufacturer minimums for this soil type, and we’ve never had a rack shift on a properly engineered Ennis install. If another installer quotes you a ground-mount price that matches their sandy-soil number, that’s a red flag.
Yes, and it’s good news. The open blackland prairie around Ennis means wide, unobstructed solar exposure with almost no horizon shading from trees or hills. Annual sun hours here are strong, and most rooftops can capture southern and western exposure cleanly. That means systems in Ennis often produce slightly better than the same system would in hillier or heavily treed parts of the state. We factor real local production data into every quote, not a generic calculator.
Yes. We file all the Oncor interconnection applications, net metering agreements, and Ennis city permit paperwork for you. We’ve done it enough times to know exactly what the city and Oncor will ask for, including the panel upgrade documentation that stalls so many Ennis applications. You sign where we tell you to sign, and we chase the rest. Call (877) 550-6892 for a free estimate that includes all of this, in writing, before you commit.
If a salesman needs an answer tonight, the answer is no. Take two weeks. Think about it. When you’re ready, call (877) 550-6892 and ask for Gus. He’ll pick up.
