Fast, Reliable Solar Panel Installation Across Dallas
A typical rooftop solar installation in Dallas runs $14,000 to $27,000 before the federal tax credit, depending on system size, roof condition, and whether your home needs an electrical panel upgrade. Most Dallas permitting and interconnection timelines run 4 to 8 weeks from signed contract to powered-on system, with Oncor approving the connection separately from your retail electric provider’s buyback agreement. We’re a locally owned shop, not an out-of-state sales crew, and we’ll walk you through the Dallas-specific two-contract process before you spend a dime. Call Gus’s Solar at (877) 550-6892 for a straight answer on what solar will actually cost on your Dallas roof.
Gus Petrakis founded this company in 2011, and he still answers his own phone. If you live in East Dallas, Oak Cliff, Lake Highlands, or anywhere else in the city, the person quoting your system is the same person standing behind it when it’s done.
Why Gus’s Solar Is Dallas’s Preferred Solar Panel Installation Company
Dallas homeowners have been burned too many times by door-knockers with laminated sales sheets and out-of-state call centers that vanish after the contract is signed. Gus’s Solar runs against that grain. We publish our address, our license number, and our owner’s name. Gus Petrakis puts his own name on the truck. That matters in a city where solar has become a magnet for aggressive sales tactics.
Our Solar Panel Installation team handles the entire job in-house, from the first roof inspection to the final Oncor interconnection. No subs, no hand-offs. You’ll recognize the crew on installation day because they’re the same people who showed up for the estimate, in uniform and background-checked.
We also understand the Dallas electricity landscape better than a national outfit ever could. Dallas sits in the deregulated ERCOT market, where Oncor owns the poles and wires, but you buy your power from a Retail Electric Provider. Solar introduces a wrinkle: you need Oncor to approve the physical interconnection, and you need an REP that actually credits your exported solar energy. Get those two pieces out of sync, and you’ll have a working solar array that saves you nothing. We’ve fixed that exact mess for Dallas homeowners more times than we can count, and we prevent it from the start.
Every job carries our 90-Day Done Right Promise in writing. If it’s not right, Gus makes it right. One call brings him back.
Our Solar Panel Installation Services in Dallas
Rooftop Solar Installation
Rooftop solar in Dallas runs $14,000 to $27,000 for a typical 7 to 12 kW system, and the math starts with your actual electric bill, not a glossy brochure. Bring us a bill, Gus will bring you the math. We quote the year-25 output, not the day-one number, because Dallas summers punish undersized systems as panels degrade. The goal is a system that still covers your peak July load in 2049, not just on installation day.
Solar System Design & Permitting
Design and permitting for a Dallas solar system typically runs $1,500 to $3,000 as a line item within the full installation, and it’s where local knowledge separates the pros from the pop-ups. Dallas requires city permits through the Development Services Department, and if your home sits in a historic district like Swiss Avenue or Munger Place, street-facing panel placement faces design review. We handle the paperwork, the drawings, and the back-and-forth so you don’t have to decode Dallas code.
Solar Panel Replacement
If an existing system in Dallas is failing, panel replacement typically runs $4,000 to $9,000 depending on the number of panels, whether the racking or wiring needs updating, and whether your old system predates current NEC rapid-shutdown requirements. Hail damage is the most common culprit we see in Dallas. The city sits squarely in Hail Alley, and panels that lack IEC 61215 impact-resistance ratings crack under the kind of large-hail events we get every few years. We match replacement panels to your existing inverter, or upgrade the whole system if the old hardware is no longer supported.
Roof-Mount & Tile Roof Solar
Mounting solar on a Dallas roof runs $1,200 to $2,800 above standard installation costs when the roof is tile, steep-pitch, or unusually old, because flashing and penetration work takes longer and has to be done right. Older Dallas neighborhoods like Oak Cliff and East Dallas are full of 1920s and 1950s homes with roofs that were never designed for modern solar racking. We flash every penetration properly, and we don’t hand that work to a sub. Gus’s crew does it personally.

Trusted Brands We Service in Dallas
We install and service equipment from the brands Dallas homeowners trust: Panasonic, Canadian Solar, JinkoSolar, and FranklinWH, among others. Because we’re local, we keep common parts and replacement components in stock for fast turnaround on warranty work and repairs across the city. If a microinverter fails in Lakewood or a power optimizer goes down in Preston Hollow, we don’t wait on a freight shipment from California. We also work with Enphase, Tesla Powerwall, and SolarEdge hardware, which matters when your existing system needs a repair or expansion and you want it done without a two-month wait.
Common Solar Panel Installation Problems We See in Dallas Homes
- Interconnection stalls from a bad REP match: The homeowner picks a Retail Electric Provider that doesn’t offer a solar buyback tariff. Oncor approves the physical connection, but the customer gets zero credit for exported power, and the system’s payback math falls apart. We check the REP’s tariff before we ever pull a permit.
- Undersized systems from day-one output claims: Some installers size Dallas systems using the panel’s brand-new production numbers instead of the year-25 estimate. A few years of heat and UV degradation later, the array falls short on the hottest August afternoons, exactly when you need it most. We quote the long-horizon number.
- Hail damage on unrated panels: Dallas sits in Hail Alley, and large-hail events hit hard. Panels without IEC 61215 impact-resistance ratings crack under that kind of force, and the manufacturer’s warranty often won’t cover hail. We spec impact-rated panels for Dallas roofs because we’ve seen the alternative.
- 100-amp panel bottlenecks in older neighborhoods: Much of the 75201-75210 corridor runs on original 100-amp electrical service, especially in Oak Cliff and East Dallas. Oncor won’t approve interconnection until the panel is upgraded, which adds $2,500 to $5,000 to the job and surprises buyers who weren’t warned. We flag this in the estimate, never after the contract is signed.

FAQs - Solar Panel Installation in Dallas
Why does solar in Dallas require two separate contracts, and how do I avoid getting zero credit for my exported power?
Dallas requires two separate agreements because Oncor owns the wires and approves the physical interconnection, while your Retail Electric Provider sets the buyback tariff for the excess power you export. If your REP doesn’t offer a solar buyback plan, you’ll get approved by Oncor but received no credit for the power you send back to the grid. We check your REP’s tariff before we file anything, and we’ll tell you which providers actually credit excess generation. Call (877) 550-6892 and we’ll walk you through the current REP options.
Do I need to upgrade my 100-amp electrical panel before installing solar in East Dallas or Oak Cliff?
Yes, in most cases the original 100-amp panels on 1920s through 1950s homes in East Dallas and Oak Cliff must be upgraded to 200 amps before Oncor will approve your solar interconnection. That upgrade typically runs $2,500 to $5,000, and it’s a cost many national sales quotes conveniently leave out. We include it in the estimate from day one so there are no surprises.
Can I install solar panels on the street-facing roof of my historic home in Swiss Avenue or Munger Place?
No, in most cases Dallas historic preservation overlays in districts like Swiss Avenue and Munger Place restrict street-facing panel placement, and design review will reject or stall your permit if you try. The workaround is placing panels on the rear roof plane, which typically requires a smaller array or higher-efficiency panels to hit the same production target. We’ve done this for historic homes across Oak Cliff and East Dallas, and we know how to design around the review board.
How do Dallas hailstorms affect solar panel warranties and what should I look for?
Dallas hailstorms crack panels that lack IEC 61215 impact-resistance certification, and many manufacturer warranties exclude hail damage from coverage, even when the panels are new. Look for that specific rating in the spec sheet before you sign, and ask whether the installer will provide the documentation in writing. We spec impact-rated panels for Dallas roofs because the alternative is a five-figure replacement bill after the first big storm.
Does the intense Dallas heat reduce my solar system’s output enough to change my sizing calculation?
Yes, sustained Dallas heat above 100°F suppresses panel output efficiency by 8 to 15 percent on the hottest days, and that small degradation compounds over the life of the system. A system sized to the day-one production number will fall short in its fifth or tenth summer. We size using the year-25 production estimate, which means a slightly larger array today that still covers your July peak load two decades from now.
