Fast, Reliable Commercial Solar Installation Across Granbury
If you own a commercial building or operation in Granbury, the math on solar has shifted. February 2021 changed everything for Hood County businesses that watched freezers thaw and registers go dark while ERCOT’s isolated grid had nowhere to pull power from. Commercial solar in Granbury now means something different than it did five years ago: it’s about keeping your doors open when the lake area goes quiet and cold. Gus’s Solar installs commercial systems sized for that reality, with battery backup built in where it makes sense. Call (877) 550-6892 and bring us a bill. We’ll bring you the math.
Why Gus’s Solar Is Granbury’s Preferred Commercial Solar Installation Company
We’re not a door-knocking crew that parachutes into Hood County for a week and moves on. Gus Petrakis started this business in 2011, and his name is on the truck, the quote, and the warranty. Granbury business owners call us because they can call Gus. A live person answers the phone 24/7, not a call center in another state. When a system underperforms around Lake Granbury, Gus is the one who notices it on monitoring and calls you, not the other way around.
Our crew knows the difference between a 1970s shoreline building in the 76048 zip code and a 2010s tilt-wall shop out toward the northern growth corridor. That matters when panel placement, roof load, and electrical service are all in play. Every install is done by our own background-checked, uniformed crew, never handed off to a sub. And every job carries the 90-Day Done Right Promise in writing: if it’s not right, Gus makes it right, one call brings him back.
We also stand by the L.O.C.A.L. values: Local roots, On time, Community first, Accountable, Loyal. Our customers in Granbury are our neighbors at the hardware store, not account numbers.
Our Commercial Solar Installation Services in Granbury
Commercial Rooftop Solar
Rooftop solar for Granbury retail, office, and mixed-use buildings is our most requested commercial service. The flat roofs common on commercial construction here handle ballasted racking well, and Granbury’s 230+ sunny days a year mean the production curve is strong. We work with Panasonic and Canadian Solar panels and design around your actual building loads, not a generic template. If your roof is older, we’ll tell you before you spend a dollar; sometimes a roofing overlay belongs in the budget before panels go up.

Warehouse & Industrial Solar
Warehouses and light industrial buildings in Granbury carry big roofs and big bills. Air-conditioning loads through July and August run hard, which is exactly when solar production peaks. We’ve seen warehouse operators around the 76049 industrial pockets cut peak-hour utility demand charges substantially with a well-sized array. Every design starts with your interval data from the utility, not a square-footage guess. If a salesman needs an answer tonight, the answer is no. We’ll give you the year-25 output, not the day-one brochure number.

Solar Carport Installation
Carports solve a real problem for Granbury businesses: limited roof space or HOA-facing elevation restrictions. A solar carport puts generation over parking, shades vehicles through triple-digit summers, and often sidesteps visibility covenants that govern panels on buildings. We’ve built carports for Granbury offices and retail sites where the southern exposure over the parking lot was far better than the roofline anyway. The concrete work is done by the team, engineered for North Central Texas wind and ice loads.

Commercial Battery Storage
Battery storage is the piece that makes solar work through Hood County’s ice events. When panels are sheeted in ice and grid power is absent, a FranklinWH or similar commercial battery bank keeps essential circuits alive for days. Granbury business owners are more motivated by backup power than utility savings alone, and the local attachment rate on storage runs far higher than in typical DFW commercial work. We size storage for multi-day scenarios, which is a different design conversation than the grid-tie-only systems still common elsewhere.

We’ll tell you honestly whether the system is worth repairing or whether the equipment has aged past its useful life.
Common Commercial Solar Installation Problems We See in Granbury Homes
- Undersized electrical service. Older Lake Granbury shoreline commercial structures, originally permitted as seasonal uses under Hood County’s unincorporated zoning, often sit on 100-amp or smaller service entrances. A panel upgrade is usually a line item before interconnection can happen, and we price it up front rather than as a “discovered” surprise.
- Roof structures not engineered for added solar weight. Buildings put up in the 1970s through early 1990s around the lake were rarely designed for the dead load a ballasted commercial array adds. We review existing structural drawings, or bring in an engineer when needed, before panels touch the roof.
- HOA and street-visibility rules on newer construction. Commercial properties in newer Granbury subdivisions and planned developments sometimes carry covenants that limit panel visibility from the street. A carport or a western roof plane can often work better than the obvious south-facing elevation.
- Icing and weather-related equipment strain. Gulf-driven winter ice events are a recurring feature of Granbury’s climate. We use cold-rated conductors, properly flashed penetrations, and weather-sealed connections throughout, and we’ve seen systems built with cheaper components fail within two winters because the install didn’t account for ice cycling.
Pricing for Commercial Solar Installation in Granbury, TX
For a small-to-mid commercial rooftop array in Granbury, most projects land between $2.40 and $3.20 per watt installed and commissioned before incentives. A 50 kW system, common for a Granbury retail or office building, typically runs $120,000 to $160,000. Warehouse systems from 100 kW to 250 kW generally fall in the $240,000 to $750,000 range depending on roof condition, tilt, and whether structural reinforcement is needed. Battery storage runs an additional $35,000 to $120,000 for most commercial configurations. The things that move the number here: service-entrance upgrades on older shoreline properties, roof span reinforcement on 1970s-1990s buildings, and whether you want storage sized for multi-day backup or just demand shaving.
