Fast, Reliable Commercial Solar Installation Across Garland
Commercial solar installation in Garland runs a different set of numbers than the rest of the metro. Garland Power & Light sets its export credit at avoided cost, not retail rate, so the entire sizing question changes. A system sized for Richardson or Mesquite will leave money on the table here. Gus Petrakis has been quoting Garland commercial jobs against actual GP&L bills for years, and that is the difference between a system that pencils out and one that does not. Call (877) 550-6892 and bring a bill. We’ll bring the math.
Why Gus’s Solar Is Garland’s Preferred Commercial Solar Installation Company
We’re a locally owned, owner-operated shop that has been doing this since 2011. Gus Petrakis puts his name on the truck and answers his own phone. When a Garland business owner calls with a question about a GP&L interconnection filing or a hail-damaged array, they talk to the person who actually signs the work, not a call center three states away.
Our crews work in Garland every week. We know the older west-side ZIP codes like 75043 and 75041 where original 200-amp service is rare and panel upgrades are the norm before any solar work starts. We know the Firewheel area in 75044 where HOA review adds a step. We know the industrial corridors along I-30 and the warehouse districts off Miller Road. That local knowledge shows up in the quote: no generic assumptions, no surprised line items halfway through the job. And every commercial install is backed by our 90-Day Done Right Promise, in writing. If it’s not right, one call brings Gus back.
Our Commercial Solar Installation Services in Garland
Commercial Rooftop Solar
Flat commercial roofs across Garland’s warehouse and retail stock are ideal candidates for rooftop solar, but the panel selection has to account for something most installers skip: summer roof-deck temperatures above 150°F. We compare temperature coefficients between panels like Qcells and Canadian Solar so the production estimate matches what the first August true-up statement will actually show.

Warehouse & Industrial Solar
Large-footprint buildings near State Highway 78 and the industrial parks south of I-30 have the roof area to support meaningful arrays. The sizing math, though, has to run against Garland Power & Light’s avoided-cost credit. We target a 95-100% offset for these buildings and we’ll show you exactly why over-building past that point does not pay for itself in Garland.

Solar Carport Installation
For commercial properties in Garland where the roof is shaded, aging, or already carrying too much equipment, a solar carport does the same job from the parking lot. We’ve built carports for businesses along the Firewheel corridor and in the 75045 ZIP code where roof geometry simply was not cooperative. A carport also gives employees shaded parking, which no one in a North Texas August complains about.

Commercial Battery Storage
Because GP&L credits excess generation at avoided cost rather than retail, storing your own power makes more financial sense in Garland than in many neighboring cities. We pair commercial arrays with Solar Battery Storage & Backup in Garland, using FranklinWH battery systems sized to shift your highest-demand hours off the grid. For Garland businesses, that often means covering the late-afternoon peak when summer heat pushes demand charges up and panel output down.

Trusted Brands We Service in Garland
We work with the industry’s leading equipment brands, including Panasonic, Canadian Solar, JinkoSolar, and FranklinWH. More importantly for Garland commercial customers, we stock common replacement parts and service components locally, so a failed optimizer or a hail-damaged panel does not mean waiting two weeks on a freight shipment. We service what we install, and we also maintain and repair systems other companies put in, including Solar Panel Cleaning in Garland. If your existing array is underperforming, call us. We will tell you honestly whether it is worth fixing or whether leaving it alone is the better financial move.
Common Commercial Solar Installation Problems We See in Garland
- Oversized arrays from a generic net-metering assumption. Installers who do not know Garland Power & Light’s avoided-cost structure build the system too big, and the excess kilowatt-hours never earn their installed cost back. We size Garland arrays to offset 95-100% of real consumption, no more.
- Original 100-amp electrical panels blocking interconnection. Many Garland commercial and mixed-use buildings from the 1950s through the 1980s still run on 100-amp service. GP&L will not schedule interconnection until the panel is upgraded to 200-amp, and if the solar quote did not include that line item, the customer gets an ugly surprise.
- High temperature coefficient panels underperforming on hot roofs. Garland roof decks hit 150°F in summer, and a panel with a poor temperature coefficient loses more output per degree than the spec sheet might suggest. A panel comparison against local conditions, not a brochure number, is what keeps the first-year production estimate honest.
- Hoad approval delays in Firewheel-area commercial properties. The 75044 corridor has active homeowner and commercial associations that require a private approval step before the city permit process starts. We handle that paperwork for you, but it adds time, and a quote that ignores it sets an unrealistic schedule.
Pricing for Commercial Solar Installation in Garland, TX
A commercial rooftop solar install on a small warehouse or retail building in Garland typically runs $2.10 to $2.65 per watt before incentives, which on a 50 kW system translates to $105,000 to $132,500. Larger industrial arrays over 100 kW can come in closer to $1.80 to $2.25 per watt. A commercial solar carport in Garland generally runs $2.60 to $3.10 per watt because of the structural steel involved. Commercial battery storage, depending on capacity, runs $900 to $1,300 per kWh installed. We also handle Garland EV Charger Installation. A 100-amp to 200-amp panel upgrade, when required, adds roughly $3,500 to $6,500 depending on your meter layout and the distance from the main. These are honest Garland numbers, not a national brochure. We quote from your actual GP&L bill and tell you to take two weeks before signing anything. If a salesman needs an answer tonight, the answer is no.

The biggest variable in Garland is not equipment cost. It is the GP&L sizing decision. We will show you two proposals side by side: one built around avoided-cost math, one built like an Oncor-territory job. The difference in payback period is usually stark.

FAQs - Commercial Solar Installation in Garland
It caps the sensible array size at roughly 95-100% of annual consumption. Because Garland Power & Light pays avoided cost rather than retail for excess generation, every kilowatt-hour you export earns back only a fraction of what a kilowatt-hour you use is worth. That changes the arithmetic entirely. In a deregulated Oncor-territory city like Richardson, you can shop retail plans that make larger systems pay. In Garland, building beyond your own usage means buying equipment that will never earn its keep. We size every Garland array to the GP&L true-up, not to a generic net-metering assumption. Call (877) 550-6892 for a quote built off your actual bill, not a brochure.
A 100-amp electrical panel cannot safely handle the added load and interconnection requirements that Garland Power & Light enforces, so GP&L will not approve the interconnection until the panel is upgraded to 200-amp service. Many Garland commercial and mixed-use buildings built between the 1950s and 1980s still carry original 100-amp panels, especially across the older west and central ZIP codes like 75043, 75041, and 75045. Any honest Garland solar quote should include a panel assessment up front. Ours always does, and we include the upgrade cost in the proposal so there is no surprise line item later.
Roof-deck temperatures in Garland regularly exceed 150°F in July and August, and panels lose measurable output per degree above their testing standard. That makes temperature coefficient the most important spec for a Garland commercial array. A panel like the Qcells duo or a Canadian Solar HiKu with a low temperature coefficient will outperform a budget panel with a mediocre one, and the difference shows up directly in your August and September production numbers. We compare panels against local roof temperatures in every Garland proposal. Give us a call at (877) 550-6892 and we’ll walk you through the comparison for your specific roof.
Rapid shutdown is a firefighter safety requirement that shuts off DC current at the panel level within seconds, and Firewheel-area commercial properties in the 75044 ZIP code face an extra layer: their HOAs and commercial associations often require documentation that rapid shutdown and all other electrical safety gear meets the latest code before they will sign off on the project. We handle the HOA paperwork and the technical compliance in one pass. It adds a few weeks to the schedule, and we include that in the timeline from the start.
Properties with shaded roofs, aging roofing materials, or heavy rooftop equipment should consider a solar carport. It gives you the same generation capacity without adding load to a roof that may already be near its structural limit. In Garland, we see carports work especially well for businesses along the I-30 corridor and in the 75046 ZIP code where large parking lots sit under full North Texas sun with no tree cover. Carports also shade employee and customer vehicles, which is a real comfort benefit in a city that logs over 90 days above 95°F most summers. Call (877) 550-6892 to get an honest comparison of rooftop versus carport for your property.
For commercial maintenance calls in Garland, we typically respond same-day or next-day. Our crews are in Garland multiple times every week, and we keep common commercial components stocked locally, so a failed optimizer or a hail-affected panel does not strand your array offline while parts ship from out of state. A live person answers our phone 24/7, so when you call about a production drop or an error code, you talk to a person who can actually do something about it, not a voicemail.
If you are considering Commercial Solar Installation in Garland, the smartest first step is a free, no-pressure quote built off your actual GP&L bill. Gus Petrakis will show you the year-25 output numbers, not the day-one brochure figure. Bring a bill, we’ll bring the math. And take two weeks. The price will be the same. Call (877) 550-6892 to schedule your free estimate.
