Fast, Reliable Solar Panel Installation Across Granbury
Solar panel installation in Granbury costs between $18,500 and $34,000 for a typical 8-12 kW rooftop system before the federal tax credit, with most lake-area homes landing in the $22,000-$28,000 range once panel upgrades are factored in. We’re Gus’s Solar, and we’ve been installing systems on Granbury homes long enough to know the difference between a 200-amp tract house and a 1980s lakefront place with a 100-amp service that needs real work before any panel goes up. If you’re in the 76048 or 76049 zip code and want straight numbers off your actual utility bill, call (877) 550-6892 and ask for Gus. He’ll bring you the math, not a sales pitch.
Why Gus’s Solar Is Granbury’s Preferred Solar Panel Installation Company
Granbury homeowners don’t need another door-knocker with a laminated photo of solar panels. They need someone who knows that a shoreline home off Waters Edge Drive typically carries an undersized service entrance, or that several golf-course communities along the 76048 corridor have covenants restricting panel visibility from the street. That’s what we deal with every week, and it’s why the Granbury homeowners who call us tend to stay with us for maintenance, monitoring, and the eventual battery add-on.
Gus Petrakis founded this company in 2011 and put his own name on the truck. When you call (877) 550-6892, a live person answers. Not a voicemail tree, not a call center in another state. Gus reads your bill with you, quotes the year-25 output instead of the day-one brochure number, and tells you to take two weeks before you sign anything. If a salesman needs an answer tonight, the answer is no. That rule comes from watching too many Granbury retirees get burned by out-of-state outfits that vanish after the paperwork clears.
Local Knowledge That Actually Matters
Granbury sits in the Cross Timbers region with 230-plus sunny days a year. That’s real production potential, and it’s why solar makes sense here. But the same geography that gives you excellent sun also puts you in the path of Gulf-driven winter ice events. February 2021 wasn’t a fluke. It was a preview. We size battery storage for multi-day outages where panels are sheeted in ice and the grid is down simultaneously. That’s a Granbury problem, not a Fort Worth problem, and it changes how we design systems for homes along Lake Granbury.
Our Solar Panel Installation Services in Granbury
Every Granbury install starts with the same question: what does your HOA allow, and what can your panel actually handle? Here’s how we work through the most common services.
Rooftop Solar Installation
A rooftop array on a Granbury home with good southern exposure typically produces 1,400-1,600 kWh per installed kW annually, among the best production ratios in North Texas. We handle the full install with Gus’s own crew, not subcontractors. Background-checked, uniformed technicians do the work, and every roof penetration gets flashed properly and inspected before we call the job done. For homes in Pecan Plantation or the lake-area subdivisions, we verify HOA requirements before we ever put a ladder on the roof.

Solar System Design & Permitting
Granbury’s mix of older lake homes and newer northern subdivisions means no two designs look alike. We pull Hood County permits, handle the structural review, and design around whatever your HOA requires. If your subdivision says panels go on the rear roof plane only, we design for that and get it in writing before install day. The design phase is also where we catch the hundred-amp panel problem, because failing an interconnection review after the array is mounted costs you weeks.

Solar Panel Replacement
Granbury’s hail season runs March through May, and we’ve replaced plenty of panels after a bad storm off Lake Granbury. If your array took hail damage or your older panels have degraded below 80% output, we’ll match the replacement to your original system or upgrade you to something better. If you have a written estimate from another company, bring it in. We’ll give you a free second opinion, and we won’t pressure you to decide before you’re ready.

Roof-Mount & Tile Roof Solar
Granbury has a surprising number of tile-roof homes, particularly in the newer lakeview subdivisions. Tile roofs require different mounting hardware and a slower, more careful install than composition shingle. Gus’s crew has done enough of these to know which tiles to pull, how to flash the penetrations, and how to keep the roofline clean. We won’t hand your tile roof to a sub who’s never touched one. That’s not how we work.

Trusted Brands We Service in Granbury
We work with equipment we’d put on our own homes: Qcells, REC, and SunPower panels paired with Enphase microinverters or Tesla Powerwall storage. That’s not a sales-menu list; it’s what performs in Granbury’s heat and handles the ice. We keep common parts and replacement panels in local inventory, which means a warranty swap or repair doesn’t wait on a truck from Dallas. If your inverter trips during a storm, a live person answers the phone at (877) 550-6892 and Gus’s crew comes out. The 90-Day Done Right Promise is in writing on every job. If it’s not right, one call brings Gus back.
Common Solar Panel Installation Problems We See in Granbury Homes
- HOA violations from street-facing panels. Several Granbury subdivisions, particularly newer developments on the north and east outskirts, have covenants that restrict panel visibility from the street. Installing on the wrong roof plane gets you a violation letter and a reinstall bill. We check the covenants before we design, not after the array is up.
- Undersized 100-amp service entrances on lake-area homes. Many Lake Granbury shoreline properties in the 76048 zip code were originally built as seasonal structures under Hood County unincorporated zoning. They often carry 100-amp or smaller panels. Solar interconnection won’t pass without an upgrade, so we scope it upfront and bundle it into the quote instead of surprising you mid-project.
- Inverter shutdowns during ice events. When rapid shutdown protocols trigger during grid instability, inverters can shut down even if panels are fine. If your battery was sized for a sunny afternoon outage rather than a Uri-level ice storm, you’ll come up short. We size storage for the multi-day scenario, not the brochure case.
- Degraded output from heat and age. Granbury summers push triple digits for weeks. Panels lose efficiency in extreme heat, and older panels degrade faster. If your production has dropped noticeably since install, we’ll test the array and tell you honestly whether replacement makes sense or whether cleaning and maintenance will do it.
Pricing for Solar Panel Installation in Granbury, TX
A typical rooftop solar installation in Granbury runs $18,500-$34,000 before tax credits. Most homes fall between $22,000 and $28,000 for an 8-10 kW system, depending on roof condition, HOA constraints, and whether the project includes an electrical panel upgrade. Panel upgrades for lake-area homes with 100-amp service typically add $2,500-$4,500. Battery backup runs $9,000-$16,000 depending on capacity, and given what February 2021 did to Hood County, we recommend at least one battery for every shoreline home. Here’s the structure:
- Rooftop solar installation (8 kW): $20,000-$26,000
- Rooftop solar installation (12 kW): $28,000-$34,000
- Electrical panel upgrade (100A to 200A): $2,500-$4,500
- Battery backup (single Powerwall-class unit): $9,000-$13,000
- Solar panel replacement (per panel, labor included): $350-$650
- Solar removal & reinstall for roof replacement: $2,000-$4,500

How Granbury’s Ice Storms and Lake Climate Shape Solar Design
Winter Storm Uri changed how Granbury thinks about solar. Before 2021, most homeowners saw solar as a way to shrink the July and August electric bill, which is real: AC drives enormous load here, and 230-plus sunny days makes solar production unusually strong for North Central Texas. After Uri, the conversation shifted. Hood County is on the ERCOT grid with no neighboring-state backup, and when the grid collapsed, days without power became the norm, not the exception. That’s why we now size battery storage for a multi-day outage scenario where panels are covered in ice and can’t recharge the battery. Panels don’t produce when they’re sheeted over, so your battery’s capacity is the thing that carries you through. Every shoreline home we design today assumes at least one full day of ice coverage, and most assume two. That’s not marketing. That’s what Granbury’s geography demands.
We recently completed a solar panel installation on a 1980s lakefront home in the 76048 zip code near Lake Granbury. The original 100-amp service entrance could not support the Tesla Powerwall and 8.4 kW rooftop array our design called for, so we bundled a 200-amp panel upgrade and roof reinforcement before mounting REC Alpha Pure panels with Enphase microinverters. The homeowners’ HOA required panels to be placed only on the rear roof plane to stay invisible from the street, and our interconnection approval with United Cooperative Services was expedited because we handled the rapid shutdown and net metering paperwork directly. That job is what a Granbury install actually looks like: HOA compliance, panel work, and a battery sized for ice.

FAQs - Solar Panel Installation in Granbury
Granbury itself doesn’t require it, but many subdivisions do. Several lakeside and golf-course communities in the 76048 and 76049 zip codes have covenants that restrict panel visibility from the street, often requiring rear-roof or side-roof placement. We pull the HOA documents before we design, mark the approved roof planes, and get written confirmation where needed. Call (877) 550-6892 and tell us your subdivision; we’ve likely already worked in it and can tell you what to expect.
Most likely yes. Lake Granbury shoreline homes built as seasonal structures under Hood County unincorporated zoning often carry 100-amp or smaller service entrances, and solar interconnection won’t pass without upgrading to at least 200 amps. We scope that upfront and bundle it into the quote, so there’s no surprise line item after the array is mounted.
Ice sheets over panels cut production to near zero until the ice melts, which can take days. During that window, your battery is the sole power source, so we size storage for the multi-day scenario, not the sunny-afternoon outage. If your system predates Uri and you have a single battery, it may not carry you through the next major ice event. We can assess and add capacity. Call (877) 550-6892 for an honest read on what you’ve got.
Yes, United Cooperative Services offers net metering for residential solar, but the export credit rates have changed over the years and vary by rate class. We handle the interconnection paperwork directly and will quote your system based on current United rates, not older, more generous ones. The math matters, and we’d rather show you the real number up front than surprise you after the install.
Quality panels from Qcells, REC, or SunPower typically degrade at 0.25%-0.5% per year, meaning 92-93% of original output at year 25. Granbury’s heat and hail exposure make panel quality more important than in milder climates because cheap panels degrade faster under sustained triple-digit conditions. We quote the year-25 output, not the day-one brochure number, so you’ll see the long-horizon math before you sign.
