Fast, Reliable Commercial Solar Installation Across Granbury
Commercial solar installation in Granbury runs $2.10-$2.85 per watt for most rooftop systems, meaning a 50kW array typically lands between $105,000 and $142,000 before incentives. Battery storage adds $800-$1,100 per kWh of capacity, and federal tax credits still cover 30% of the installed cost. We schedule Granbury site visits within 48 hours and most commercial installs complete in 4-8 weeks.
We know Granbury because we work here. Not as a sales territory, but as neighbors. The lake, the historic square, the way Hood County’s older shoreline properties were never built for modern electrical loads. That matters when you’re running a business, a church, a marina, or a lakeside event venue. Call Gus’s Solar at (877) 550-6892 and you’ll talk to a person who knows the difference between a 76048 lakeside panel and a 76049 new-build subdivision. No call center. No pressure to sign tonight.
Why Gus’s Solar Is Granbury’s Preferred Commercial Solar Installation Company
We’re Granbury locals with over 29 years in the solar trade, and our name is on the building. Gus Petrakis started this business in 2011, and he still answers his own phone. That matters here because Granbury is not a generic suburb. It’s a lakeside community where word travels fast. When a business on the square gets a good install, three other owners hear about it by Friday. When a contractor botches a lakeside job, that story travels faster.
Our Granbury customers tend to ask the same questions: “Will it hold up in an ice storm?” “What happens if the grid goes down for three days in February again?” “Did you pull a permit with Hood County?” We have answers because we’ve worked through every one of those scenarios right here. Our Commercial Solar Installation team handles everything from a 25kW retail rooftop to a 250kW ground-mount for an agricultural operation. Background-checked, uniformed technicians show up on time. The quote we give you is the price you pay. And the 90-Day Done Right Promise is in writing: if it’s not done right, Gus makes it right.
Our Commercial Solar Installation Services in Granbury
Here’s what we actually install for Granbury businesses, warehouses, farms, and lake-area properties.
Commercial Rooftop Solar
For retail buildings, offices, and churches around the Granbury square and along Highway 377, rooftop solar is the most common entry point. We engineer every system for the actual roof we’re standing on. In Granbury’s Cross Timbers climate, that means racking rated for hail, wiring rated for 230+ sun days, and panels from manufacturers we trust. We quote the year-25 output, not the day-one brochure number.
Warehouse & Industrial Solar
Several industrial buildings in the 76048 and 76049 corridors have flat or low-slope roofs that are ideal for high-density solar. Where a warehouse is running refrigeration or climate control, the economics typically work in our favor because July and August demand charges are brutal in North Central Texas. A properly sized array plus battery peaks shaves those spikes. That’s not a green talking point. It’s a line item on a utility bill.
Solar Carport Installation
Carports serve two purposes in Granbury: they generate power and they shade vehicles through triple-digit Julys. We do them for churches, medical offices, and multi-tenant retail where the parking lot becomes the power plant. Because a carport is a structure, we handle the engineering, the Hood County permitting, and the concrete work. No hand-offs to a sub. Gus’s crew does the install.
Commercial Battery Storage
This is the part of commercial solar where Granbury differs from most of the DFW metro. After Winter Storm Uri left Hood County dark for days in February 2021, battery storage stopped being an add-on. It became the point. We size batteries for multi-day ice events, not just overnight load-shifting. A lakeside marina, for example, needs enough backup to keep pumps and security systems running for 72 hours if panels are sheeted in ice and the grid is simultaneously down. Nobody forgets Uri here. That lived experience drives how we size every battery bank.
Agricultural & Ground-Mount Solar
Hood County has real working land outside the lake neighborhoods. Ranches and agricultural operations around the 76049 zip and toward the county line often have the open acreage for ground-mount arrays that a city lot can’t support. We do ground-mounts for pump houses, barns, workshops, and full ranch operations. The math is different out there because usage is different. We build the quote off your actual electric bill, not a generic template.
Commercial Solar Maintenance
Hail season in North Central Texas is real, and Granbury sees ice storms that coat panels for days. We offer ongoing maintenance for commercial systems: panel cleaning, inverter checks, performance monitoring, and post-storm inspections. If something fails, we catch it because we monitor it. That’s the difference between a company that finishes the install and a company that stays accountable to you.

Trusted Brands We Service in Granbury
We work with equipment we’d put on our own buildings. That includes Panasonic and Canadian Solar panels, SolarEdge inverters, and FranklinWH batteries. We stock inverters, rapid-shutdown hardware, and common replacement parts locally, so when a Granbury business calls about a fault code, we typically show up with the fix on the truck. No waiting two weeks on a part from a distribution center out of state.
Common Commercial Solar Installation Problems We See in Granbury Homes and Businesses
Granbury has its own set of recurring problems. Here’s what we run into:
- Undersized 100-amp service entrances on older lake properties. Many original Lake Granbury shoreline structures built in the 1970s and 1980s were permitted as weekend cabins under Hood County’s unincorporated zoning. When you convert one to a business or vacation rental and push a 30kW commercial array through a 100-amp panel, the utility interconnection fails or the breaker trips. A service upgrade isn’t an upsell here. It’s a requirement.
- HOA visibility covenants in northern and eastern subdivisions. The 2000s-era subdivisions on Granbury’s outskirts often restrict roof-mounted panel visibility from the street. If a contractor skips design review with the HOA, the system gets red-tagged and the owner pays fines. We read the covenants before we draw the plans.
- Ice-storm battery sizing that’s too small. A battery bank sized for overnight load-shifting works fine in July. It fails in February when panels are ice-covered for three days and the ERCOT grid is down. We saw it happen. We size for it.
- Roof decks never engineered for racking. Older lake-area buildings often have roof decks built to weekend-cabin standards, not modern solar load requirements. We inspect every roof before we quote, and we flag structural work honestly. If the deck needs reinforcement, you’ll know before you sign.

FAQs - Commercial Solar Installation in Granbury
Why do so many commercial solar quotes in Granbury include an electrical panel upgrade?
Because a large share of the older lake-area shoreline properties in the 76048 zip were originally built as seasonal structures under Hood County’s unincorporated zoning, and many still carry 100-amp service entrances that cannot handle solar interconnection without an upgrade. We see it constantly. A 100-amp to 200-amp panel upgrade adds $4,500-$8,000 and is a near-standard line item for lake-area commercial buildings, unlike most DFW metro buildings that already have 200-amp panels. Call (877) 550-6892 and we’ll check your panel before you commit to anything.
How does Winter Storm Uri change the battery sizing for a Granbury business?
It changes the central design assumption. Before February 2021, most commercial battery banks were sized for overnight load-shifting, which works fine in summer. After Uri left Hood County without power for days, the question changed from “how much do I shift?” to “how long do I last when the grid is down and my panels are iced over?” That means sizing for 48-72 hour outages, not 8-10 hour overnight backup. We walk you through that math on every commercial quote.
Can a lakeside commercial building in Granbury get net metering with a 100-amp panel?
No. Utility interconnection standards require a panel that can safely handle the solar backfeed plus the building’s existing load. A 100-amp panel on an older lakeside structure typically can’t pass that test. The panel upgrade has to happen first. We’ve done this enough times that we flag it in the first phone call, not halfway through permitting. If you’re looking at a lake-area building with an old panel, expect the upgrade in your quote.
Do HOA rules in Granbury’s newer subdivisions really affect commercial solar design?
Yes. The HOA covenants in several of the 2000s-era subdivisions on Granbury’s northern and eastern outskirts regulate what’s visible from the street, and some restrict roof-mounted panel placement. A contractor who ignores the covenants gets the project red-tagged and the owner stuck with fines and a non-permitted system. We pull the covenant documents before we finalize a design. It’s part of the job done right.
What maintenance do Granbury commercial solar systems need after hail and ice storms?
After a North Central Texas hail event, we recommend a physical panel inspection for microcracks, a racking torque check, and a performance check against baseline output. After an ice storm, panels should be checked for stress fractures from thermal cycling, and the battery bank should be run through a discharge test to confirm it holds the capacity your outage plan assumes. We offer annual maintenance contracts for Granbury commercial systems so these checks happen on schedule, not after something already failed. Call (877) 550-6892 to set one up.
