Fast, Reliable Solar Panel Installation Across Lewisville
Lewisville homeowners installing solar in 2026 are looking at a realistic system cost between $18,500 and $32,000 before the federal tax credit, depending on roof condition, panel count, and whether your electrical panel can handle the load. If you live in the older 75057 ZIP near downtown, there’s a good chance you’ll need a 200-amp panel upgrade before Oncor will even look at your interconnection application, and that adds $2,000 to $3,500 to the job. We’re Gus’s Solar, and we’ve been walking Lewisville homeowners through this exact math for years. Call (877) 550-6892 and bring us your electric bill. We’ll quote the year-25 output, not the day-one brochure number.
Why Gus’s Solar Is Lewisville’s Preferred Solar Panel Installation Company
Lewisville isn’t a cookie-cutter solar market, and we don’t treat it like one. The housing stock here splits almost perfectly between 1970s-era ranch homes in 75057 and 1990s tract development in 75067 and 75077, and each half has its own set of solar headaches. Gus Petrakis put his name on this company in 2011, and he still answers his own phone. Lewisville homeowners don’t get a call center or a rotating cast of sales reps. They get Gus, and they get his crew, background-checked and uniformed, doing the install themselves. No subs. No disappearing act after the paperwork clears.
We work in Lewisville every week, not once a quarter. That means we know what the Oncor interconnection desk is asking for this month, we know which roof decks on the older 75057 ranches are holding up and which ones aren’t, and we know what the hail season did to last year’s installs. The 90-Day Done Right Promise applies to every job we do here: if it’s not right, Gus makes it right, in writing. One call brings him back. If a salesman needs an answer tonight, the answer is no. We’d rather you take two weeks and think about it. The price will be the same.
Our Solar Panel Installation Services in Lewisville
Rooftop Solar Installation
Most Lewisville homes are good candidates for rooftop solar, but the low-slope ranches in 75057 need different racking than the steeper pitches in 75077. We flash every roof penetration properly, and we don’t hand the roof work to a sub. The same crew that mounts the rails is the crew that seals the flashing. If your roof is 20 to 30 years old, we’ll tell you before you sign anything, because mounting panels on a roof that’s near end-of-life is a bad way to spend $20,000.

Solar System Design & Permitting
Design work in Lewisville is where the real local knowledge pays off. We size systems off your actual electric bill, not a square-footage guess. We account for thermal derating on those hot dark composition shingle roofs all over 75067, because that’s a real production loss a solar calculator won’t tell you about. And we handle the City of Lewisville permit process and the Oncor interconnection application ourselves. You don’t chase paperwork. You get a timeline and a callback when the permit clears.

Solar Panel Replacement
Hail happens in Lewisville. It’s not a question of if, it’s a question of which year. When storm damage cracks a panel or bends a rail, we come out, assess what’s still producing, and replace what’s dead. We stock common replacement parts locally for faster turnaround, and we’ll work directly with your insurance adjuster on the claim. Class 4 impact-rated panels are standard in our Lewisville quotes for a reason. The North Texas hail corridor doesn’t care what the brochure says.

Roof-Mount & Tile Roof Solar
True tile roofs are rare in Lewisville, but the 1980s-era brick veneer two-stories near downtown sometimes have decorative tile accents or low-slope composition sections that need special mounting. We’ve done both. Our crew knows how to mount on low-slope roofs without creating leak points, and we’ll tell you if a tile accent area should just be left uncovered rather than risk cracking tiles that are 40 years old and irreplaceable.

Trusted Brands We Service in Lewisville
We install and service equipment from Enphase, Tesla, SolarEdge, and FranklinWH, among others. For Lewisville customers, Enphase microinverters have become our most common recommendation, mostly because they handle partial shading and Texas heat better than string inverters, and because their per-panel monitoring makes hail-damage diagnosis much faster. We stock common Enphase and Tesla components for local callbacks, so a failed microinverter in 75077 doesn’t mean waiting a week for a part to ship from California. The equipment matters. The installer matters more. We’re the Solar Panel Installation team that stands behind the brand name on the box.
Common Solar Panel Installation Problems We See in Lewisville Homes
- Failing interconnection on 100-amp panels. Homes in 75057 built in the 1970s and 80s frequently still run on 100-amp service. Oncor will not approve solar interconnection on an undersized panel. The fix is a 200-amp upgrade before the install, and we flag this in the first quote so it doesn’t blindside you at permit time.
- Thermal derating on aged composition roofs. Those dark shingle roofs all over central Lewisville get brutally hot in July, and heat cuts panel efficiency. We’ll show you the derated production number, not the sunny-day brochure figure, so your year-one output matches your expectations.
- Zinsco and Federal Pacific panels hiding in older homes. In the neighborhoods near historic downtown, we still find original Zinsco panels that have been quietly powering homes for 40-plus years. Those panels are fire hazards, and solar interconnection legally triggers replacement. We budget for it upfront.
- Hail damage to existing racking and panels. After a North Texas storm, systems go offline from cracked glass or bent rails. We schedule removal and reinstall work alongside insurance claims so you’re not waiting months to get back online.

FAQs - Solar Panel Installation in Lewisville
Yes, if your home still has a 100-amp electrical panel, which is common in Lewisville’s older 75057 housing stock. Oncor requires adequate electrical capacity before granting interconnection approval, and a 100-amp panel does not meet that bar. Plan on $2,000 to $3,500 for a 200-amp upgrade, and we’ll flag it in your first quote so there are no surprises. Call (877) 550-6892 and we’ll tell you over the phone what your panel situation likely looks like based on your home’s age.
In Oncor’s deregulated territory, you must pick a retail electric provider that offers a solar buyback plan, and the wrong choice can quietly erase your solar savings. We walk Lewisville customers through the current crop of buyback-friendly REPs, compare per-kWh export rates, and help you switch before your system goes live. It’s a two-step process that installers in utility-territory cities never have to deal with, and we’ve been doing it for Lewisville customers for years. Call (877) 550-6892 before you sign anything.
The right panels will. Lewisville sits in the North Texas hail corridor, one of the highest hail-frequency zones in the country, so Class 4 impact-rated panels are standard in our quotes. Those panels are tested against 2-inch hail at terminal velocity. That doesn’t mean hail can’t break them, but it means they’re engineered for exactly what Lewisville throws at them. We’ll show you the impact rating on every panel we quote, not just the wattage.
Yes. After a storm damages racking or panels, we schedule removal and reinstall work alongside your insurance claim so you’re not waiting months to get back online. This typically runs $1,200 to $2,800 depending on system size. We’ll come out, document the damage for your adjuster, and give you a written timeline for the reinstall. Call (877) 550-6892 and we’ll be there, usually within a few days of your call.
Because the spec sheet number assumes a cool, sunny test condition, and your Lewisville roof hits 150 degrees in July. Hot dark composition shingles cause thermal derating, which cuts real-world output by 8 to 15 percent. We quote the year-25 output, not the day-one brochure number, so you see what the system will actually produce, not what the manufacturer’s lab test says it could. That’s the honest math, and it’s the math we’ve been showing Lewisville homeowners since 2011.
If you’re in Lewisville and you’re tired of door-knockers who need an answer tonight, call us instead. We’ll quote your real numbers off your real bill, give you two weeks to think about it, and answer the phone when you call back. Call (877) 550-6892 for a free estimate.
