Fast, Reliable Solar Battery Storage & Backup Across McKinney

A typical solar battery install in McKinney runs $11,500 to $18,000 before the federal tax credit, with most homeowners pairing a battery with either a new array or an existing system already on the roof. Our crews work in McKinney every week, and we can usually have someone out to your home within 48 hours for an assessment. If you’re tired of watching your refrigerator shut off every time Oncor’s grid stumbles during a summer storm, call Gus’s Solar at (877) 550-6892. We’ll walk you through what a battery actually does for your house, not what a brochure says it might do.

Call (877) 550-6892

McKinney isn’t like Plano or Frisco when it comes to solar battery work. The HOA layer here is real, the hail is real, and the older homes near downtown come with their own set of headaches. We know the difference between a Stonebridge Ranch ARB submission and a Craig Ranch one, and we know which roof planes on a curved-street lot in 75070 actually catch sun. That’s the kind of thing you only learn by doing the work here, week after week.

Why Gus’s Solar Is McKinney’s Preferred Solar Battery Storage & Backup Company

Gus Petrakis founded this company in 2011 and he still answers his own phone. That’s not a marketing line. Call (877) 550-6892 and you’ll get a person, not a queue. McKinney homeowners have dealt with enough door-knockers quoting one number on the porch and another at the kitchen table. We quote off your actual utility bill, and the number we give you is the number you pay.

Our Solar Battery Storage & Backup team has worked on homes across 75069, 75070, and 75071, from the historic streets near downtown to the new construction pushing north past 380. We’ve seen the ARB letters from Stonebridge Ranch. We’ve walked Craig Ranch lots where the south roof faces the street and the HOA says no visible panels. We’ve replaced hail-damaged equipment on homes that didn’t even know they had damage until their production numbers dropped. That local experience is what prevents surprises mid-project.

The 90-Day Done Right Promise applies to every solar job we do in McKinney. If it’s not done right, Gus makes it right. In writing. No arbitration clause, no “we’ll review your concern.” One call and he’s back at your house.

Tesla Powerwall Installation

The Tesla Powerwall 3 is the most common battery we install in McKinney, and for good reason. It pairs cleanly with most existing inverters, handles whole-home backup well, and the app doesn’t require a computer science degree to read. A single Powerwall 3 installed in McKinney typically runs $13,000 to $16,500 including gateway and installation. Most homes in 75070 and 75071 with a 4-ton or larger AC will want two units if whole-home backup is the goal, which pushes the range to $24,000 to $29,000 before incentives.

Enphase IQ Battery Installation

If your McKinney home already has an Enphase microinverter system, sticking with the same ecosystem usually makes the most sense. The Enphase IQ Battery 5P runs around $12,000 to $15,000 installed as a retrofit, and the modular design means you can start with one and add capacity later without ripping anything out. We’ve put these on homes in Fairview and Melissa too, and the 15-year warranty holds up well against the hail and heat we get in Collin County.

Whole-Home Backup Power

Whole-home backup in McKinney means sizing the battery system to carry your AC, not just your lights and fridge. That’s the part where national installers often underquote, because they don’t know what a July afternoon in Collin County does to a 2,800-square-foot brick home’s load profile. Our team sizes off your actual usage data, not a square-footage chart. A typical McKinney whole-home backup system with two batteries and the necessary electrical work falls in the $22,000 to $32,000 range before the federal credit.

Battery Retrofit for Existing Solar

If you already have panels on your McKinney roof and you’re tired of exporting power to the grid for pennies while you buy it back at full retail, a battery retrofit is the fix. Most retrofits run $11,000 to $19,000 depending on your inverter and panel situation. Some systems built before 2019 need a new inverter or a DC-coupled solution, and we’ll tell you that up front. No bait-and-switch. Bring us a bill, we’ll bring you the math.

Trusted Brands We Service in McKinney

We work with the brands McKinney homeowners already know: Tesla, Enphase, FranklinWH, and SolarEdge. That means if your existing system uses one of those platforms, we can usually integrate a battery without ripping out your inverter. For new installs, we recommend what fits your roof, your HOA constraints, and your actual usage, not whichever brand has the best spiff that month. We keep common parts locally stocked for faster turnaround across McKinney and the surrounding area, so a warranty replacement doesn’t mean waiting two weeks on a freight truck.

Common Solar Battery Storage & Backup Problems We See in McKinney Homes

  • HOA flip-flops after the sale. McKinney’s master-planned communities require ARB approval, and sometimes the ARC approves a plan only to have a neighbor complaint trigger a re-review. We handle the resubmission and, when possible, design around it from the start so there’s nothing to re-review.
  • Hail damage that doesn’t show on the panel glass. Class-4 panels can take an impact that looks cosmetic but compromises output. After a big hail event in McKinney, we often run production diagnostics on systems whose owners noticed a drop but couldn’t see damage. The battery’s charge rate drops, and nobody knows why until we check the array.
  • 100-amp service on older downtown homes. Pre-1970s homes in 75069 frequently have a 100A main panel. Oncor will not approve a whole-home battery interconnection without a panel upgrade. We quote the upgrade as part of the project, so you’re not surprised by a second invoice later.
  • East-west array confusion. If your south roof faces the street and the HOA says no visible panels, your quote will show an east-west split array. That’s not a design error. It’s McKinney reality on curved-street lots. We explain it clearly so you’re not comparing apples to a neighbor’s brochure number.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"Four different companies knocked on my door in one summer and every one of them wanted a signature that evening. Gus has a shop with his name on it, gave me the numbers on paper, and told me to take a fortnight and think about it."

Winifred Castellano · Verified customer
★★★★★

"Honest quoting and good workmanship. He is not the cheapest quote I got, by some way, and he told me that himself and explained what the difference bought. I chose him anyway and I am glad."

Alistair Fennimore · Verified customer
★★★★★

"The install itself was excellent and the system performs as modelled. Permitting and the utility interconnection took about four months, most of it out of his hands, though the waiting was still frustrating."
