Fast, Reliable Commercial Solar Installation Across McKinney
Commercial solar installation in McKinney typically runs $2.10-$2.65 per watt for rooftop systems, meaning a 100 kW warehouse array lands between $210,000 and $265,000 before the federal tax credit and depreciation. Most projects take 60-90 days from first site visit to interconnection. If you’re running a warehouse, retail building, or distribution center in 75069, 75070, or 75071, this page covers what it actually takes to get panels on your roof and a system feeding your meter. Call (877) 550-6892 and we’ll walk the site, read your utility bill, and give you a number that holds.
Why Gus’s Solar Is McKinney’s Preferred Commercial Solar Installation Company
Gus Petrakis has been installing solar in North Texas since 2011, and his name is on every truck, every invoice, and every permit we file in McKinney. We’re not a national outfit running crews out of a call center three states away. When a Craig Ranch warehouse manager calls about a monitoring alert, Gus’s crew shows up. When a Stonebridge Ranch retail owner needs an HOA packet revised before the Architectural Review Board meeting, we handle it in person.
McKinney customers trust us because we understand how this city actually works. The HOA layer here isn’t a side note: it’s the deciding factor on whether your best roof plane is usable. We’ve sat through enough ARB hearings in Stonebridge Ranch and Craig Ranch to know what gets approved, what gets kicked back, and how to design around it before you spend a dime on engineering. We also answer the phone. A live person, 24/7. No voicemail tree. No ticket queue. That matters when your battery system throws a fault at 6 AM on a Monday in July and your entire operation is about to start pulling full retail-rate power.
Our McKinney work is backed by the 90-Day Done Right Promise: if something isn’t right, Gus makes it right, in writing, on every single job. That’s the standard we’ve held for 29 years in the solar trades, and it’s why most of our McKinney commercial customers come from referrals, not door knocks.
Our Commercial Solar Installation Services in McKinney
We install and service full commercial solar systems across McKinney, from small office buildings near downtown to large tilt-wall warehouses along the Stacy Road corridor. Here’s where we do most of our work:
Commercial Rooftop Solar
This is the core of what we do in McKinney. Most commercial roofs here are either TPO membranes on newer tilt-wall warehouses or modified bitumen on older retail buildings. We work with Qcells and REC panels on a range of racking systems, including ballasted flat-roof mounts that don’t penetrate the membrane. For a 50,000 square foot warehouse in 75070, you’re usually looking at a 150-300 kW system depending on HVAC loads and roof obstructions. Before we quote anything, we check the HOA governing documents if your property falls under a master-planned community covenant, even for commercial parcels.

Solar Carport Installation
When rooftop space gets eaten up by RTU units, skylights, or a street-facing HOA restriction, carports are the workaround that keeps your production on track. A solar carport in McKinney typically runs $3.00-$3.75 per watt installed, higher than rooftop because of the steel structure and foundation work. We’ve designed carport arrays for office parking lots in 75071 where the roof’s only clear plane faced a public street and the HOA said no. The carport went over the employee lot, and the system still hit 92% of the original production target.

Commercial Battery Storage
McKinney sits in Texas’s deregulated retail electricity market, which means your buyback rate depends on your retail plan. If your REP pays you wholesale for exported power, a battery can shift your solar production to cover evening and early-morning loads when your building is still pulling grid power. We install FranklinWH and Tesla commercial storage systems, sized to your interval data, not a brochure. A 100 kW / 200 kWh battery system in McKinney typically runs $180,000-$260,000 installed before incentives, and we’ll run the math off your actual 12-month usage to show whether it pencils out.

Commercial Solar Maintenance
Hail is a fact of life in Collin County. We handle post-storm inspections, inverter and optimiser replacements, and module swaps for commercial systems across McKinney. If your array took a hit in the last hail event, call (877) 550-6892 and we’ll get a crew out to assess it. We don’t charge a trip fee inside our own county, and we’ll coordinate directly with your insurance adjuster so you’re not stuck doing paperwork for two months.

Trusted Brands We Service in McKinney
We install and maintain commercial systems from Qcells, REC, and Tesla, plus Enphase and SolarEdge for power electronics. We stock common replacement parts locally so we’re not waiting on a truck from California when your inverter drops out in the middle of a McKinney summer. If you already have a system installed by another company and it’s underperforming, we’ll take a look. We don’t upsell you into a full replacement if a $400 optimiser swap fixes it.
Common Commercial Solar Installation Problems We See in McKinney Homes
- HOA Architectural Review Board rejection. This is the number one delay we see in McKinney commercial projects. Texas Property Code §202.010 protects your right to install solar, but HOAs in Stonebridge Ranch and Craig Ranch can still prohibit panels visible from public streets. If your best roof plane faces a street, the ARB will reject it. We design around this before permitting, not after.
- Main electrical panel backfeed limits. Older buildings near downtown McKinney in 75069 frequently have 400A or smaller services that can’t handle a large commercial solar interconnect without an upgrade. We check this in the first site visit and include the upgrade cost in your quote so there are no mid-project surprises.
- Hail damage on Class-4-rated modules. Even impact-rated panels crack under the right hail stone. McKinney gets multiple significant hail events a year, and we regularly get calls from business owners who discover cracked glass or dead microinverters weeks after a storm. Insurance coordination after hail is part of our maintenance work.
- Underestimated HVAC load growth. McKinney summers push 100°F+ for weeks at a time, and commercial AC systems run hard. We size arrays off your actual interval data and summer peak usage, not a square-footage rule of thumb. A system sized from the winter bill will leave you drawing grid power every afternoon in August.
Pricing for Commercial Solar Installation in McKinney, TX
Here’s what commercial solar actually costs in McKinney’s market right now:
| System Type | Typical Cost Range (McKinney) |
|---|---|
| Small office rooftop (25-50 kW) | $52,500-$132,500 |
| Mid-size warehouse rooftop (100-250 kW) | $210,000-$662,500 |
| Solar carport (per 50 kW) | $150,000-$187,500 |

| Electrical service upgrade (if required) | $8,000-$25,000 |
These ranges include equipment, installation, permitting, and interconnection paperwork with Oncor. The federal Investment Tax Credit covers 30% of the total system cost, and bonus depreciation applies to commercial systems placed in service this year. Your actual payback depends on your retail electricity rate, buyback plan, and whether the ARB forces a layout change. Bring us 12 months of utility bills and we’ll run the year-25 output forecast off your real numbers, not a brochure estimate. The estimate is free. Take two weeks to think about it. The price will be the same.

FAQs - Commercial Solar Installation in McKinney
In McKinney’s HOA-governed communities like Stonebridge Ranch and Craig Ranch, your system layout has to pass Architectural Review Board review before you can pull a permit. The HOA can prohibit panels visible from public streets, which kills a south-facing layout if the street side of your building faces south. We design around this from day one by pulling the HOA’s design guidelines, mapping street visibility, and laying out arrays that stay flush-mounted and out of sight. We just finished a 220 kW rooftop system on a distribution warehouse off Stacy Road in Craig Ranch where the ARB initially rejected the south-facing plan. Our team redesigned it as a two-plane east-west split array with SolarEdge optimisers, pulled a revised production estimate showing only a 6% annual kWh offset loss, and got ARB approval without a carport or ground mount. Interconnection with Oncor was approved the following week. Call (877) 550-6892 and we’ll check your HOA’s rules before you spend anything on engineering.
Many do. Buildings in the historic core of downtown McKinney, particularly in 75069, often have 200A-400A electrical services that predate modern solar interconnection requirements. Oncor will reject your interconnection application if your panel can’t handle the backfeed. We check the service size and available breaker space during the first site visit and include any upgrade cost in your quote upfront. A commercial panel upgrade in McKinney typically runs $8,000-$25,000 depending on service size and existing infrastructure.
McKinney sits in the North Texas hail corridor, so your panels need IEC 61215 certification and Class 4 impact resistance. Even Class-4 modules crack under severe hail, and damaged glass or microinverters can drop your production by 5-20% before anyone notices. If a storm damages your array, call (877) 550-6892 and we’ll send a crew out to assess the damage, document it for your insurance claim, and coordinate directly with your adjuster. We do post-storm inspections for McKinney commercial systems all season long, and we don’t charge a trip fee in our county.
Your payback math is entirely different depending on your retail provider and plan. In McKinney, you can shop retail plans with full net metering, partial buyback, or wholesale export rates. If your plan pays you retail credit for exported power, your solar payback shortens by 30-40%. If your REP pays you a wholesale rate for exports, a battery shifts the math in your favor by storing production for on-site use instead of selling it back cheap. We run your payback off your actual bills and your current plan terms, not a generic Texas average.
Yes. Solar carports are a standard part of our McKinney commercial work. If your warehouse roof is loaded with RTU units, skylights, or a street-facing plane that the HOA rejects, a carport over your parking lot gives you clean production space. Carports in McKinney typically run $3.00-$3.75 per watt installed, higher than rooftop because of steel and foundation costs, but they don’t touch your existing roof warranty and they shade your employees’ cars in July. We’ll show you the production difference between your rooftop options and a carport before you commit.
