Fast, Reliable Commercial Solar Installation Across Dallas
Commercial solar in Dallas means navigating two contracts instead of one. Oncor approves your interconnection, but a separate Retail Electric Provider decides what your exported power is worth. Get that pairing wrong and you’ll have panels on your roof producing power the owner never gets paid for. Gus’s Solar has been coordinating both tracks for Dallas businesses since 2011, and we quote the year-25 numbers, not the day-one brochure figure. Bring us a bill, we’ll bring you the math. Call (877) 550-6892 and Gus Petrakis will walk you through it himself.
If you own commercial property in the 75208 corridor, a warehouse off Riverfront, or a retail center in East Dallas, you already know the grid here does not play by the same rules as Austin or San Antonio. We’ll make sure your system actually gets credited for what it produces.
Why Gus’s Solar Is Dallas’s Preferred Commercial Solar Installation Company
Dallas businesses have been burned by out-of-state outfits that quote one number on the phone and another at the permit counter. That is not how we work at Gus’s Solar. Gus Petrakis put his own name on the truck in 2011, and he’s the one who answers when you call the office. Not a call center. Not a ticketing portal. One call brings Gus back, which matters when a storm takes out ten panels on a flat roof in June.
Our crew lives and works in the Dallas-Fort Worth metro. We know which ZIP codes fall under historic preservation review, which REPs actually honor buyback credits, and which flat-roof layouts will survive a Dallas hailstorm. Our 90-Day Done Right Promise is in writing on every commercial job. If it’s not right, Gus makes it right. That is not a marketing line. It is the operating code we’ve followed for 29 years in this business, and it is the L.O.C.A.L. standard: Local roots, On time, Community first, Accountable, Loyal.
Response time to Dallas itself is usually same-day for commercial calls. We carry inventory for Enphase, SolarEdge, and FranklinWH in the metro area, so a failed inverter on a 75207 warehouse does not sit dark for a week while parts ship from California. The price you get quoted is the price you pay. No signature wanted tonight. Take two weeks and think about it. The number will be the same.
Our Commercial Solar Installation Services in Dallas
Feel free to explore our full Commercial Solar Installation lineup for the complete scope of what we handle. For Dallas specifically, these are the four services most commercial property owners call us about.
Commercial Rooftop Solar
A flat commercial roof in Dallas is not the same as a residential shingle job. Hail Alley is real, and a shallow-tilt array spec’d without impact ratings will shatter the first time a March storm rolls through. We design rooftop systems for the 75201 and 75206 corridors using panels with IEC 61215 impact resistance as a baseline, not an upsell. Rooftop commercial systems in Dallas typically run $55,000 to $180,000 depending on system size, roof condition, and whether a service upgrade is needed. Most warehouses fall in the $70,000 to $120,000 band for a 40 to 100 kW array.

Warehouse & Industrial Solar
Warehouse properties off Industrial Boulevard and in the 75207 ZIP carry two burdens in Dallas: aging 100-amp service panels and Oncor interconnection queues. We coordinate both. Our crew recently completed a 48.6 kW rooftop array on a brick warehouse off Riverfront Boulevard, pairing SolarEdge inverters with REC Alpha Pure panels. The building still had original 100-amp service panels feeding the load center, so we handled the Oncor service upgrade while clearing design review for a historic overlay on the adjacent Munger Place district. The true-up statement from the customer’s REP hit on time, and they’ve been credited for exports every month since. Industrial systems commonly land between $90,000 and $250,000 depending on roof square footage and panel capacity.

Solar Carport Installation
Dallas parking lots take brutal summer sun, and a carport array turns that liability into generation. Carport installs in Dallas run $40,000 to $110,000 for a typical commercial lot covering 20 to 50 spaces, depending on steel structure engineering and panel count. We design carports to handle the same hail ratings we require on roof systems. The added benefit for a Dallas business is shade; employees and customers walking across a covered lot in August notice.

Commercial Battery Storage
February 2021 changed the conversation in Dallas. Uri knocked out power for days across the metro, and commercial owners who watched freezers thaw and servers go dark aren’t asking about solar ROI anymore. They’re asking about survival. Battery backup on a Dallas commercial property typically runs $30,000 to $90,000 before any available credits, depending on whether you need to protect critical loads like refrigeration, IT, or security systems. We install FranklinWH and Tesla Powerwall configurations sized to run those loads through a multi-day ERCOT failure. Not a few hours. Days.

Common Commercial Solar Installation Problems We See in Dallas Homes
Before you sign any proposal, know these four failure modes. We’ve fixed all of them for Dallas business owners who got quoted by someone who didn’t understand the local grid.
- REP buyback mismatch. A company signs a REP tariff that credits exports at avoided-cost rates while the Oncor interconnection agreement is still pending. The system exports power, but the owner sees zero credit for months. The REP and Oncor tracks must be cleared together, or one of them stalls the other.
- Hail-rated panels skipped. A carport or flat-roof array is laid out with shallow tilt angles that maximize summer production but ignore impact ratings. First major hailstorm shatters the panels and voids the production estimate. In Dallas, this is not a theoretical risk. It is an annual event.
- Hidden service upgrade on old buildings. A retrofit on a 1920s-era Oak Cliff commercial building hits a 100-amp panel that wasn’t included in the original payback period. The project stalls at permit review and the customer absorbs a $4,000+ upgrade cost they never saw coming. We flag this on day one, not day ninety.
- Roof condition ignored. A Dallas commercial roof with ten years of hail exposure gets a solar array bolted to it without inspection. Five years later, roof repair requires removing the entire array. We inspect first. If the roof has five years left, we tell you that before we sell you panels.
Pricing for Commercial Solar Installation in Dallas, TX
Here are the real numbers for commercial solar in Dallas. Rooftop systems generally run $55,000 to $180,000. Warehouse and industrial arrays land between $90,000 and $250,000. Carport installations come in at $40,000 to $110,000, and commercial battery storage runs $30,000 to $90,000. What drives cost is system size, roof condition, electrical service age, and whether your property falls under a historic overlay. A 1920s building in Oak Cliff with a 100-amp panel will cost more than a 2010 tilt-wall warehouse in the 75207 corridor. That’s not a surprise line item. We put it in writing before you sign.
We do not use brochure estimates. Bring your actual utility bill and your REP agreement to the table. Gus will quote the year-25 output, not the day-one brochure number. Free estimate, no trip charge inside our own county, and a Senior and Veteran 10% discount that never expires. Call (877) 550-6892.

FAQs - Commercial Solar Installation in Dallas
You need both, and they are separate. Oncor handles the physical interconnection approval, but your Retail Electric Provider is the one who credits you for exported power. If your REP’s buyback tariff is not aligned with your Oncor agreement, you will export power and see zero credit for it. This is the single most common reason Dallas commercial systems underperform their initial quotes. We coordinate both tracks before the first panel goes up. Call (877) 550-6892 and we’ll audit your current REP agreement for free.
Uri changed the math entirely. Before 2021, Dallas commercial solar was pitched as a pure ROI play. After days of no power across the metro, business owners now ask how long the lights stay on when ERCOT fails again. We size battery storage for multi-day critical load coverage, not a few hours of outage. A FranklinWH or Tesla Powerwall configuration sized for freezers, security systems, and a server room typically runs $30,000 to $90,000. The battery doesn’t always pencil out on avoided export rates in Dallas, but it doesn’t have to. It’s an insurance policy.
Standard panel degradation is 0.5% per year, leaving you at roughly 88% output in year 25. But in Dallas, hail can wipe that clean in one afternoon. Panels without IEC 61215 impact resistance can crater under the large hail events this metro regularly absorbs. We spec hail-rated panels as a baseline for every Dallas commercial roof, not as an add-on. In the 75201-75210 corridor, the added cost is roughly 5 to 8% of panel cost, and it is the cheapest insurance you’ll buy on the project.
Maybe. Oak Cliff has several historic preservation overlays, and ground-mount arrays face design review when they are visible from the street. The key is filing the right paperwork through the Dallas Landmark Commission before you submit the building permit. We have cleared ground-mount installations in 75208 and know which streets trigger the overlay review and which don’t. A ground-mount commercial system in Dallas typically runs $85,000 to $200,000 depending on racking, trenching, and panel count.
A true-up statement is your REP’s annual reconciliation of what your system exported versus what you consumed. In Dallas, it’s where you find out if your buyback plan is actually paying you. If the Oncor agreement and your REP tariff don’t match, the true-up statement shows zero credit and you’ve lost a year of exports. That’s why managing both contracts matters. Call (877) 550-6892 for an exact quote on your Dallas property. Estimates are free, and no signature is wanted tonight.
