Fast, Reliable Solar Panel Installation Across Garland
If you’re weighing solar panel installation in Garland, the real question isn’t whether the sun shines here. It does, about 5.2 peak hours a day on average. The question that actually decides whether your system pays for itself is how Garland Power & Light treats the power your panels send back to the grid. We’ll get into that below, because it changes the math more than any panel brand ever will. For now, know this: Gus’s Solar installs, permits, and interconnects rooftop solar for Garland homeowners, and we size every system off your actual GP&L bill, not a brochure. Call (877) 550-6892 and bring us a bill. We’ll bring you the math.
We’ve worked in Garland long enough to know which ZIP codes need a panel upgrade before the utility will even look at an interconnection application, and which HOA corridors add a private approval step you won’t find on the city’s permitting checklist. That local knowledge is the difference between a system that goes live in six weeks and one that sits in limbo for six months. We don’t sub the work out. Gus’s own crew does the install, flashes every roof penetration properly, and leaves your property the way we found it. A live person answers our phone 24/7. Not a ticketing portal. Call now and you’ll reach a human.
Why Gus’s Solar Is Garland’s Preferred Solar Panel Installation Company
Gus Petrakis started this company in 2011 and put his own name on the truck. That’s not a marketing line; the license number, the published address, and the guy who answers the phone are all the same person. When a Garland homeowner calls with a production question three years after install, they don’t get transferred to a support queue in another state. They get Gus. That’s the whole model.
We’ve built a strong local reputation in Garland by doing exactly what we say we’ll do. The 90-Day Done Right Promise is in writing on every solar job: if it’s not done right, Gus makes it right, and one call brings him back. No arbitration clause, no fine print. Homeowners across Garland who’ve been burned by door-to-door crews that quote one number on the phone and another at the kitchen table tend to respond well to that. We also give a 10% discount to seniors and veterans that never expires, offer a free second opinion on any written estimate, and don’t charge a trip fee inside our own county.
Response time to Garland is same-day for many service calls and typically within 24 to 48 hours for new installation consults. We schedule around your life, not the other way around. If a salesperson needs an answer tonight, our answer is no. Take two weeks. Think about it. The price will be the same when you call back.
Our Solar Panel Installation Services in Garland
Rooftop Solar Installation
Most Garland homes we work on are ranch-style or modest two-story builds from the 1950s through the 1980s. That housing stock has specific roof geometry: composition shingle roofs with shallow pitches in the older 75040 and 75041 areas, and steeper architectural shingle roofs in newer 75044 developments near Firewheel. We design each array to the actual roof plane, not a generic layout, because a south-facing array on a 4/12 pitch in Garland performs differently than the same panel count on a 7/12 pitch in Richardson. Rooftop solar installation in Garland typically runs $18,000 to $34,000 before the federal tax credit, depending on system size and whether a panel upgrade is needed, and we also provide Solar Panel Cleaning - Garland to keep your system producing at peak.

Solar System Design & Permitting
This is where a Garland-specific company earns its keep. The city of Garland requires a building permit for rooftop solar, and if you’re in an HOA jurisdiction like much of the Firewheel Town Center corridor in 75044, you need that approval before the city will even accept your permit application. We’ve seen installations stopped mid-job because an owner skipped the HOA step and the association demanded a re-roof of the affected elevation to match trim requirements. We handle the full design and permitting sequence in the right order, and we tell you upfront what your specific address will require. Design and permitting as a standalone service in Garland runs $1,200 to $3,500 depending on system complexity and whether HOA documentation is involved.

Solar Panel Replacement
Garland sits squarely in North Texas hail alley. Large-hail events happen often enough that insurers in the area increasingly require or incentivize Class 4 impact-rated panels. If your older array took storm damage, or if your panels have degraded below what your original installer promised, we replace them with current models matched to your existing racking and inverter setup where possible, and we offer Garland Solar Panel Maintenance & Monitoring to catch issues early. A full panel replacement on a typical Garland rooftop array runs $8,000 to $16,000. If your original installer is no longer in business, we’ll still service it. We’re not going anywhere.

Roof-Mount & Tile Roof Solar
Most Garland roofs are composition shingle, but we also do tile-roof solar for the handful of Mediterranean and Spanish-style homes scattered through older west Garland and some custom builds near Firewheel. Tile roofs require different flashing and mounting hardware than shingle roofs, and doing it wrong means leaks. Gus’s crew flashes every penetration properly and backs the work in writing. Roof-mount and tile roof solar installation in Garland runs $20,000 to $38,000 depending on roof condition and system size.

Trusted Brands We Service in Garland
We work with equipment from Panasonic, Canadian Solar, JinkoSolar, FranklinWH, Tesla, Enphase, SolarEdge, SunPower, Qcells, and REC. For Garland specifically, we lean on Qcells panels with Enphase microinverters more than anything else, because the temperature coefficient matters on those 150°F summer roof decks and Enphase’s rapid shutdown system adds a layer of safety for North Texas hail and wind. We stock common replacement parts locally for Garland customers, so a downed microinverter doesn’t mean waiting two weeks on a freight shipment. You can see the full Solar Panel Installation lineup on our service page, but the short version is this: we service what we install, and we install what we can stand behind.
Common Solar Panel Installation Problems We See in Garland Homes
- Arrays sized for retail-rate net metering instead of GP&L’s avoided-cost export credit. This is the big one. A system sized to “zero out” a bill under a retail-rate assumption will underperform financially in Garland, stretching the payback period years beyond what the proposal claimed. We size Garland arrays to offset roughly 95 to 100% of annual consumption, deliberately, and we’ll show you the math behind that number.
- Interconnection applications rejected because the home still has a 100-amp electrical panel. Garland’s housing wave ran from the 1950s through the 1980s, and a lot of those homes in 75040 and 75042 still carry original 100-amp panels. GP&L won’t approve interconnection on those. The panel upgrade to 200-amp service runs $2,500 to $5,000 in Garland, and it has to happen before the utility application goes in, not after.
- HOA stop-work orders in the Firewheel corridor. The newer developments around Firewheel Town Center in 75044 have active HOAs with specific panel placement and trim-matching requirements. Skipping that approval before pulling the city permit triggers a stop-work order mid-install. We’ve had to clean up that exact mess for homeowners who went with an out-of-state installer first.
- Hail damage on panels without Class 4 impact ratings. It’s not a marketing footnote in Garland. We see cracked panels and degraded output after every major hail season, and most insurers in the area now require or incentivize Class 4 ratings. If your quote doesn’t mention the hail rating, ask why.
Pricing for Solar Panel Installation in Garland, TX
Let’s talk straight numbers, because you deserve them. A typical rooftop solar installation in Garland runs $18,000 to $34,000 before the federal tax credit. The federal credit currently covers 30% of the system cost. After the credit, you’re looking at $12,600 to $23,800 net. That range varies by system size, roof condition, whether you need a panel upgrade, and whether you’re in an HOA that requires specific panel placement. Here’s a breakdown of what those numbers actually include:
- Rooftop solar installation (design, permitting, install, interconnection): $18,000 to $34,000
- Electrical panel upgrade (100-amp to 200-amp, when GP&L requires it): $2,500 to $5,000
- Solar system design and permitting (standalone): $1,200 to $3,500
- Solar panel replacement (full array, existing racking): $8,000 to $16,000
- Roof-mount and tile roof solar (full install): $20,000 to $38,000

FAQs - Solar Panel Installation in Garland
It changes it significantly. GP&L credits your excess solar generation at avoided cost, which is lower than the retail rate you pay for power you pull from the grid. That means a system sized to produce 110% or 120% of your annual usage won’t earn back the extra panel cost nearly as fast as it would in Oncor territory, where some rate structures reward larger systems. In Garland, we size arrays to offset roughly 95 to 100% of your annual consumption and we show you the payback math on that exact number before you sign anything. Call (877) 550-6892 for an exact quote based on your bill. Estimates are free.
If your Garland home was built between the 1950s and 1980s and still has its original 100-amp panel, yes, almost certainly. GP&L will not approve an interconnection application on a 100-amp panel, especially in the older west and central ZIP codes like 75040 and 75042 where original panels are common. The upgrade to 200-amp service runs $2,500 to $5,000 in Garland, and we handle it before the utility application goes in so nothing stalls; many homeowners also bundle this with our EV Charger Installation in Garland while we’re upgrading the panel. If you’re not sure what service size your panel is, we’ll check it during the free estimate.
There’s no city ordinance requiring a specific hail rating, but your insurance company likely has an opinion. Insurers across North Texas increasingly require or incentivize Class 4 impact-rated panels, and Garland’s hail alley location makes that a real purchasing decision, not a checkbox. We spec Class 4-rated panels on most Garland installs and we’ll show you the cost difference versus a standard panel so you can make an informed call with your insurer in the loop.
A string inverter runs all your panels through one central unit, so one shaded or damaged panel drags down the whole string. Microinverters put a small inverter on each panel, so each panel produces independently. On Garland roofs with partial afternoon shading from mature trees in older neighborhoods, or with the 150°F roof-deck heat that suppresses output unevenly across a roof plane, microinverters typically perform better. They also make panel-level monitoring simpler, which matters when you’re tracking production against GP&L’s export credit. We quote both options and explain the tradeoff in plain terms.
GP&L reconciles your solar production and grid usage on a monthly billing cycle, not an annual true-up like some Texas retail providers. Your bill shows your net usage and any export credit applied at the avoided-cost rate each month. That means you’ll see the financial impact of your system on every monthly bill, not once a year. What you won’t get is a big annual check for overproduction, which is exactly why we size Garland systems conservatively. If your monthly bill looks off, call us and we’ll pull your production data and help you understand what’s happening. A live person answers 24/7 at (877) 550-6892.
