Fast, Reliable Commercial Solar Installation Across Decatur
Commercial solar in Decatur works differently than it does 45 miles east in Fort Worth. You’re on Wise Electric Cooperative, not Oncor, and that single fact changes how your system should be sized, whether battery storage makes sense, and what your actual payback looks like. We’ve been installing commercial arrays across Wise County long enough to quote the year-25 output off your real utility bill, not a brochure number. If you’re a Decatur business owner or landowner wondering whether solar pencils out under co-op rules, call Gus at (877) 550-6892 and bring us a bill. We’ll bring you the math.
Why Gus’s Solar Is Decatur’s Preferred Commercial Solar Installation Company
Gus Petrakis started this company in 2011 and put his own name on the truck. That matters when you’re signing a contract for a $80,000 commercial array and you want to know the person who quoted it is the same person who’ll answer when something acts up three years later. We’re not a door-knocking crew working off a script. We’re a locally owned shop with a published address, a license number, and a live person answering the phone 24/7. No ticketing portal. No call center three states away.
Decatur business owners along US-287, around the courthouse square, and out on the large lots off FM 51 call us because we already know the co-op’s interconnection paperwork, the hail ratings that matter here, and the structural quirks of early-1900s buildings near downtown. Our Commercial Solar Installation team has done ground-mounts on ranch land, carports at industrial parks, and rooftop retrofits that required panel reinforcement before a single module went up. When you call, you get a straight answer about whether solar is worth it on your specific building, under Wise Electric Cooperative’s specific rules.
Our crew is background-checked and uniformed. Gus’s own people do the install. We don’t hand your roof off to a sub. And every job carries the 90-Day Done Right Promise in writing: if it’s not right, one call brings Gus back.
Our Commercial Solar Installation Services in Decatur
Commercial Rooftop Solar
Rooftop solar on Decatur commercial buildings means dealing with what’s actually up there. Early-1900s craftsman and Victorian buildings near the square often have legacy rafter spacing that won’t carry modern glass-glass panel weight without reinforcement. Mid-century ranch-style offices need inverter placement that keeps equipment out of the blast-furnace heat of a west-facing wall. We assess the roof structure before we quote anything, because a cheap quote that ignores rafter load is how you end up with a leaky roof and a system that underperforms.

Warehouse & Industrial Solar
Warehouses along US-287 and in Decatur’s industrial pockets have big, flat, mostly unobstructed roofs, which is exactly what solar likes. The catch in Wise County is that the co-op’s net-metering credit caps mean a warehouse array sized like one in Fort Worth will export more than it can get paid for. We size warehouse systems to your actual daytime load profile and pair them with battery storage where it makes sense, so you’re not giving electrons back to the co-op at a fraction of their value.

Solar Carport Installation
Carports serve two masters in Decatur: they generate power and they keep the Texas sun off your fleet vehicles, employee cars, or customer parking. A solar carport also sidesteps roof structural issues entirely, which matters when the building is old and the roof is questionable. If you’ve got lot space and a roof you don’t trust, a carport array can be the better play.

Commercial Battery Storage
Here’s the honest truth about Decatur: battery storage isn’t an upsell, it’s the thing that makes commercial solar work under Wise Electric Cooperative’s stricter interconnection rules. The co-op’s less generous net-metering credits mean you’re better off storing surplus than exporting it. We install FranklinWH, Tesla Powerwall, and Enphase battery systems sized to shift your solar production into the hours when the co-op’s credit rate would otherwise eat your return. For most Decatur commercial customers, the battery is what makes the payback math close.

Trusted Brands We Service in Decatur
We install and service equipment from Tesla, Enphase, SolarEdge, and FranklinWH, among others. That matters when you already have a system that’s underperforming or faulting out and you need someone who actually knows the hardware, not someone who just sells it. Because we work with these brands regularly and keep parts for them locally, turnaround on service calls in Decatur is fast. If your inverter’s throwing faults or your battery’s not cycling, we can usually diagnose and fix it without waiting on a parts shipment from across the country.
Common Commercial Solar Installation Problems We See in Decatur
- Systems sized for Oncor rules, not co-op rules. A commercial array sized off Fort Worth net-metering rates will export far more than Wise Electric Cooperative credits you for, which quietly destroys the payback you were promised. We see this most often when a national installer ran the numbers off generic assumptions instead of your actual co-op rate schedule.
- Older buildings hitting structural limits. Rooftop arrays on early-1900s buildings near the courthouse square regularly need rafter reinforcement before modern panel weights go up. Skipping that step leads to sagging, leaks, and a roof that fails early.
- Inverters overheating on west-facing walls. Decatur summers push past 100°F routinely. An inverter mounted on a west-facing wall of a mid-century ranch-style office will thermal-throttle and shorten its own life. We relocate or properly ventilate these as part of the install, not as a callback.
- Hail damage that wasn’t planned for. Wise County sits in North Texas hail country. IEC 61215 impact-resistance ratings are a real purchasing filter here, not a spec-sheet footnote. We spec panels and mounting that survive the hail Decatur actually gets.
Pricing for Commercial Solar Installation in Decatur, TX
A commercial rooftop solar installation in Decatur typically runs $2.40 to $3.10 per watt before incentives, meaning a 50 kW warehouse array lands between $120,000 and $155,000. A 100 kW system runs $240,000 to $310,000. Solar carport installations run higher, typically $3.50 to $4.50 per watt, because of the steel structure. Commercial battery storage in Decatur runs $900 to $1,400 per kWh of capacity installed, with a typical commercial pairing of 30-60 kWh adding $27,000 to $84,000. Ground-mount agricultural arrays on Decatur’s large rural lots run $2.10 to $2.80 per watt, often the lowest-cost option when land is available and the building’s roof is old. These are real Decatur numbers, built off co-op rates and local labor, not national averages. Call (877) 550-6892 for an exact quote. The estimate is free, and take two weeks to think about it. The price will be the same.

FAQs - Commercial Solar Installation in Decatur
Under Wise Electric Cooperative’s stricter interconnection rules and less generous net-metering credits, the ideal Decatur array is sized to your actual daytime consumption, not oversized to export surplus, because exported power earns less than it does under Oncor’s rules in Fort Worth. A Fort Worth warehouse might size a system to 110% of annual usage and make money on the export; in Decatur, that same oversizing wastes capital. Pairing the array with battery storage to shift surplus into evening hours recovers most of the value that the co-op’s credit cap would otherwise forfeit. Call (877) 550-6892 and we’ll run the numbers off your actual co-op bill, not a generic rate assumption.
Yes, you should repair or reinforce the roof first, because early-1900s craftsman and Victorian buildings near the Decatur courthouse square often have rafter spacing that won’t carry modern panel weight without structural work, and putting solar on a failing roof means paying twice to remove and reinstall the array later. We assess roof structure during the quote and tell you plainly if the roof needs work before panels go up. We’d rather tell you the truth up front than stick you with a leaky roof and a system you can’t use. Call us for a straight answer on your building.
A commercial solar system in Decatur typically pays back in 9 to 13 years without battery storage and 7 to 10 years with battery storage, because the battery recovers value that the co-op’s net-metering caps would otherwise forfeit. That’s longer than the 6-to-8-year payback common in Oncor territory, which is why national installers quoting Fort Worth numbers to Decatur business owners are doing them a disservice. The honest math matters, and we’ll show you the year-25 output and payback range for your specific building and rate schedule before you sign anything. Take two weeks to think about it. If a salesman needs an answer tonight, the answer is no.
Yes, ground-mounted commercial solar is a genuinely practical option on Decatur’s large rural lots outside the city core, and it’s often the better play when the building’s roof is old, structurally limited, or angled wrong. Our crew recently retrofitted a 1970s ranch-style office building off FM 51 near the courthouse square, where the original 200A service had no room for solar backfeed; we replaced the main panel, added a Tesla Powerwall 3 to shift export around the co-op’s cap, and mounted REC panels at a 25-degree azimuth to maximize the roof’s usable plane. If you’ve got acreage, a ground array avoids roof headaches entirely and lets us angle panels for maximum Decatur production. Call us and we’ll look at your land.
Decatur’s hail exposure means you should spec panels with strong IEC 61215 impact-resistance ratings and plan for periodic post-storm inspections, because Wise County sits squarely in North Texas hail country and a panel that survives a Fort Worth storm may not survive what Decatur gets. We select panels and mounting systems rated for the hail Decatur actually sees, and our Commercial Solar Maintenance service includes post-storm checks so small impact damage doesn’t become a dead string. If a hailstorm rolls through, call us; we’ll come out and look.
