Fast, Reliable Commercial Solar Installation Across Lewisville

Commercial solar installation in Lewisville typically runs $85,000 to $240,000 before incentives, depending on system size, roof condition, and whether your building needs a panel upgrade first. That panel upgrade question is the one most out-of-town installers don’t ask until the permit gets flagged. Gus’s Solar has been working Lewisville commercial roofs long enough to know the 75057 ZIP differently than a crew that drove up from Houston this morning.

Call (877) 550-6892

We’re the local owner-operated shop that shows up when we say we will, quotes the year-25 output instead of the day-one brochure number, and tells you to take two weeks before you sign anything. Call (877) 550-6892 and a live person answers. Not a voicemail, not a call center. Gus Petrakis put his name on the truck for a reason.

Why Gus’s Solar Is Lewisville’s Preferred Commercial Solar Installation Company

We’re not a pop-up sales crew running a blitz through the DFW metroplex. Gus’s Solar was founded in 2011, and the owner’s name, address, and license number are published right out in the open. When a Lewisville business owner calls, they talk to Gus or one of his crew. When something goes wrong three years after install, the same people come back. That’s the L.O.C.A.L. code we operate by: Local roots, On time, Community first, Accountable, Loyal.

Our response time to Lewisville commercial properties is same-day for emergencies and within 48 hours for quotes. The dispatcher schedules from our Dallas-Fort Worth office, but the crews working your roof know the difference between a 75057 ranch-era commercial building and a 75077 tilt-wall warehouse. That local knowledge is not something you can fake with a satellite image and a sales script.

We’ve also seen what happens when a national outfit quotes a Lewisville job over the phone: they assume a 200-amp panel, assume a clean roof deck, assume the customer knows how Oncor’s deregulated market works. Then the permit gets hung up, the price changes, and the customer’s left holding a contract they didn’t agree to. We don’t work that way. Bring us a bill, we’ll bring you the math.

Our Commercial Solar Installation Services in Lewisville

Commercial Rooftop Solar

Rooftop solar on Lewisville commercial buildings starts with a structural assessment of what’s actually up there. The older core around downtown Lewisville in 75057 is heavy with 1970s and 1980s construction, low-slope rooflines, and aging composition shingles that hold heat. We quote the real thermal derating on those hot dark rooftops, not the lab-conditions output from a brochure. If the roof needs work, we’ll tell you before you sign, not after the panels are staged in the parking lot.

Commercial Rooftop Solar

Warehouse & Industrial Solar

Warehouse and industrial solar in Lewisville means big flat roofs and big energy loads. The 75067 corridor along I-35E has tilt-wall and metal buildings with strong roofs and plenty of square footage, but you still need to account for the hail question. We’ll spec a system that survives a North Texas spring storm, not one that shatters into an insurance claim the first time golf-ball hail rolls through. That means Class 4 impact-rated modules, not whatever was cheapest on the pallet.

Solar Carport Installation

A solar carport in Lewisville does double duty: it generates power and shades vehicles from a July sun that pushes 100°F without blinking. For commercial lots with limited roof capacity or tenants who don’t want penetrations in their membrane roof, carports are often the cleaner play. We design them for the wind loads and hail exposure that Lewisville actually gets, not a generic spec pulled from a national playbook.

Commercial Battery Storage

Commercial battery storage pairs with your array to bank power for the hours when Oncor’s rates climb or the grid stutters. We work with FranklinWH and other reputable battery manufacturers, and we’ll size the system against your actual load profile from your utility bill. Not a guess. A lot of Lewisville businesses with refrigeration, server rooms, or production equipment lose real money in an outage. A battery changes that math.

Trusted Brands We Service in Lewisville

We install and service equipment from Panasonic, Canadian Solar, JinkoSolar, FranklinWH, and several other manufacturers we’ve vetted over 29 years in the trade. For Lewisville commercial customers, that means parts availability is rarely a problem. We keep common components in local inventory, and when a warranty replacement is needed, we handle the claim instead of handing you a phone number and wishing you luck. If a hailstorm cracks a module on a warehouse off Business 121, you want a crew that can get it swapped before your production numbers crater for a quarter.

Common Commercial Solar Installation Problems We See in Lewisville

  • The Federal Pacific Stab-Lok surprise. In the older 75057 neighborhoods around historic downtown Lewisville, electricians still find original Federal Pacific Stab-Lok or Zinsco panels quietly feeding power to buildings that have been standing for 40+ years. Those panels are flagged as fire hazards, and solar interconnection legally triggers a full replacement, which can add $2,000 to $3,500 to a job that was already quoted. We flag this on the first site visit, not at the permit counter.
  • Quoting a 150-amp service assumption on a 1970s-era commercial building. Then discovering the panel situation above mid-permit. The budget blows up after the contract is signed, and the customer’s left angry at the installer for something that was discoverable from the start. That’s why our quoting process for Lewisville jobs starts with the electrical panel, not the roof.
  • Spec-ing standard panels without Class 4 impact resistance. Lewisville sits in the North Texas hail corridor, one of the highest hail-frequency zones in the country. A low-slope commercial roof with standard modules is a shattered-module insurance claim waiting on the next spring storm. We won’t put that roof in that position.
  • Failing to explain Oncor’s deregulated retail choice. Lewisville is in Oncor’s deregulated territory, which means the customer picks their own retail electric provider. Pick a default provider with lousy solar buyback, and the true-up statement shows near-zero credit, and the customer blames the installer for a bad production estimate. We walk every Lewisville customer through choosing a solar-buyback-friendly REP before the system goes live. It’s part of the job here.

Pricing for Commercial Solar Installation in Lewisville, TX

A typical commercial rooftop solar array in Lewisville runs $85,000 to $240,000 before the federal tax credit, depending on system size, roof condition, and whether your building needs a panel upgrade first. Smaller ground-mount systems on acreage properties in the 75077 ZIP start around $60,000. Carport installations land between $120,000 and $300,000 depending on how many bays you’re covering. Battery storage adds $15,000 to $90,000 based on capacity and whether you need whole-building backup or just critical loads.

What moves the number in Lewisville specifically: the age of your building. The 75057 stock from the 1970s and 1980s is more likely to need that $2,000 to $3,500 electrical panel replacement before interconnection. The 75067 and 75077 buildings from the 1990s and 2000s usually have 200-amp panels already, but those roofs are now 20 to 30 years old and often need a re-roof conversation alongside the solar quote. We don’t hide any of this. The number we quote is the number you pay. Estimates are free, and you can bring us your utility bill and we’ll build the math off your actual usage.

What Lewisville Customers Say

Trusted by homeowners across Lewisville and surrounding areas.

★★★★★

"He modelled it on my actual bill and the current export rates rather than the old ones, and told me plainly that the payback was longer than the door knockers had claimed. Then it came in about where he said it would."

Octavius Redmond · Verified customer
★★★★★

"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."

Sunita Balakrishnan · Verified customer
★★★★★

"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."
