AfterFast, Reliable Commercial Solar Installation Across Dallas
Commercial solar installation in Dallas runs $2.10 to $3.40 per watt for most rooftops, and the biggest variable is not panel cost. It is whether your building’s electrical service can handle the load and whether your Retail Electric Provider actually credits your excess generation. That second piece trips up more Dallas businesses than any other factor in the entire process. Gus Petrakis has been untangling Dallas’s two-contract ERCOT solar requirements since 2011, and his crew knows which REPs in this market write buyback tariffs worth signing and which ones quietly zero out your export credits. Call (877) 550-6892 and bring us a bill. We will bring you the math.
Why Gus’s Solar Is Dallas’s Preferred Commercial Solar Installation Company
Dallas commercial property owners have watched national installers roll through town, quote a brochure number, and disappear when the Oncor interconnection request gets kicked back for a panel upgrade. That does not happen with Gus’s Solar because Gus Petrakis publishes his name, address, and license number on every quote, and his crew does the install themselves. No subs. No call center three states away. A live person answers the phone 24/7, which matters when your array trips offline on a Friday afternoon and you need someone who actually knows where your disconnect is.
The Commercial Solar Installation team at Gus’s Solar has handled projects from small retail rooftops in the Design District to industrial warehouses off South Lamar and carports at distribution centers in the 75224 corridor. We have coordinated Oncor service upgrades, historic district design reviews, and REP buyback contracts in Dallas long enough that the city’s permitting office knows our work. Take two weeks to think about any quote we give you. The price will be the same.
Our Commercial Solar Installation Services in Dallas
Commercial Rooftop Solar
Flat commercial rooftops in Dallas make up the bulk of our work, and they come with a specific set of concerns here. Hail Alley storms roll through the metro regularly, so we spec IEC 61215 impact-rated modules as standard on commercial jobs, not as an upsell. The 1950s brick warehouses scattered through Oak Cliff and East Dallas often carry original 100-amp or 60-amp services, which means a service upgrade has to happen before Oncor will even look at your interconnection application. We coordinate that upgrade as part of the job so you are not stuck holding a permit rejection while a national crew has already left town.
Warehouse & Industrial Solar
Large industrial rooftops in the 75223 and 75224 areas have the square footage to support serious arrays, but the electrical demand profile matters just as much as the roof area. We design warehouse systems around your actual load curve, which usually means pairing solar with battery storage to shave demand charges. Dallas sits in the ERCOT deregulated grid, and Oncor handles the physical interconnection while your REP handles generation billing. Those are two separate approval tracks, and a mismatch between them is the most common reason we see industrial solar projects approved but never credited.
Solar Carport Installation
Carports solve a real problem for Dallas businesses that do not have enough unobstructed rooftop space. They also happen to be one of the cleanest ways to add generation without touching a 100-year-old roof membrane. We design and build carport arrays to Dallas wind load requirements, and we anchor them properly for the clay-heavy soils common across the metro. If your property sits in a historic overlay district where rooftop panels face design review, a carport array can often avoid that process entirely. That is a local shortcut worth knowing about.
Commercial Battery Storage
The February 2021 Winter Storm Uri changed commercial solar in Dallas permanently. Businesses that sat dark for days are no longer asking about payback periods. They are asking about resilience. We pair commercial arrays with Tesla Powerpack, Enphase, or FranklinWH battery systems sized to keep critical loads running through the next ERCOT failure. Commercial battery storage also helps manage demand charges, which in Oncor territory can represent a meaningful slice of your monthly bill. A system that generates without storage is only doing half the job in Dallas.

Trusted Brands We Service in Dallas
We install and maintain equipment from Tesla, Enphase, SolarEdge, and FranklinWH, and we stock enough common components locally that warranty replacements do not mean a two-week wait on a truck from California. For most Dallas commercial rooftops, we default to Enphase microinverters because they simplify rapid shutdown compliance for fire code and perform well on the hot, high-irradiance summer days when your rooftop is pushing 140 degrees. If your roof has shade from neighboring buildings off Mockingbird or industrial structures along I-30, we will specify accordingly.
Common Commercial Solar Installation Problems We See in Dallas Homes
- Signing a REP contract without reading the buyback tariff. Permits clear with Oncor, the array activates, and then the owner discovers their REP credits exports at a fraction of retail or not at all. The project never reaches positive cash flow. We check your REP tariff before we design anything.
- Old electrical services stalling interconnection. Commercial buildings in Oak Cliff’s 75208 and East Dallas’s 75206 frequently carry 100-amp services that cannot handle a modern solar array. Installers who skip the service upgrade get repeated Oncor rejection notices and leave the customer holding the mess.
- Historic district design review blocking street-facing arrays. Swiss Avenue and Munger Place have preservation overlays that restrict visible panel placement. A hurried installer files a permit without checking the overlay and gets a stop-work order that delays the project for months. We check the overlay status on every Dallas job before design begins.
- Hail-rated modules being treated as optional. Dallas sits squarely in Hail Alley, and unrated panels on a flat commercial rooftop are a liability waiting for the next big storm. Without IEC 61215 impact-rated modules, one severe hail event craters the array and voids both the production estimate and the warranty coverage.

FAQs - Commercial Solar Installation in Dallas
Do Dallas commercial solar systems need two separate approvals before they can operate?
Yes. Dallas sits in the ERCOT deregulated grid, which means Oncor handles your interconnection agreement while your Retail Electric Provider handles buyback credits. These are two separate contracts, and they must match or your array can be approved but uncredited. We coordinate both tracks so the paperwork lines up before the panels go on the roof. Call (877) 550-6892 if you want us to review your current REP tariff.
How does the February 2021 Winter Storm Uri change the design of a commercial solar project in Dallas?
Winter Storm Uri shifted most Dallas commercial solar projects from pure ROI math to resilience design. Businesses that lost power for days are now asking for battery storage sized to keep critical loads running through the next ERCOT failure. That means we design systems around your essential circuits, not just your annual consumption. It also means battery capacity gets bigger and the payback conversation gets more honest.
My warehouse is in the 75208 Oak Cliff area and has an old 100-amp service. Can you still install commercial solar?
Yes, but the service upgrade is part of the job. Older commercial buildings in Oak Cliff and East Dallas frequently carry 100-amp or 60-amp services that Oncor will not accept for interconnection. We coordinate the upgrade with Oncor before the array goes in, so you do not get a permit rejection two months into the project. That upgrade adds cost, and we will tell you the real number up front.
Will hail in Dallas damage my commercial solar panels?
Only if the modules are not rated for impact. Dallas sits in Hail Alley, and large hail events hit the metro regularly. We spec IEC 61215 impact-rated modules as standard on every commercial job because unrated panels on a flat rooftop are a liability. If your array goes in without that rating, a single severe storm can crater the panels and void the production estimate and the warranty.
Why does the same commercial solar array pay back differently in Dallas than in Fort Worth or Austin?
Because your REP buyback tariff in Dallas determines what your excess generation is actually worth, and those tariffs vary widely. Austin and San Antonio have municipal utilities with standardized solar credits. Dallas does not. One Dallas REP might credit exports at close to retail, another might credit almost nothing. The same array produces the same power, but the payback swings wildly depending on which REP contract you signed. We check the tariff before we quote anything.
