AfterFast, Reliable Solar Battery Storage & Backup Across Celina
Solar battery storage in Celina typically runs $9,500-$18,500 installed, and a properly sized system keeps your lights, refrigerator, and HVAC running through the rolling blackouts and hail-season outages that hit Collin County without warning. If you’re in Celina and tired of watching your brand-new solar panels sit useless while the grid goes dark, we can help. Our Solar Battery Storage & Backup team has been retrofitting and installing batteries across Celina’s master-planned communities long enough to know exactly what CoServ Electric will approve and what your HOA will allow. Call (877) 550-6892 and ask for Gus. He’ll walk you through the math off your actual bill.
Why Gus’s Solar Is Celina’s Preferred Solar Battery Storage & Backup Company
We’re not a pop-up sales crew that chases hail storms and disappears. Gus Petrakis founded Gus’s Solar in 2011, and his name, address, and license number are published for anyone in Celina to verify. When you call us about a Powerwall or an Enphase IQ Battery, a live person answers. Not a voicemail. Not a ticket queue. Gus answers his own phone at 2 a.m. when a storm knocks out your power and you need to know why your battery didn’t kick in.
Our technicians are background-checked and uniformed, and it’s Gus’s own crew on your property, never a subcontractor. We quote the year-25 output, not the day-one brochure number. 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.
What sets us apart in Celina specifically is that we’ve spent years navigating CoServ Electric’s interconnection paperwork. Most DFW installers are used to Oncor’s process. CoServ is different. Their approval timelines, their export rules, their transformer capacity quirks in newly built sections of Celina, all of it matters when you’re sizing a battery. If you get it wrong, your system sits unapproved and your backup does nothing. We get it right the first time, and we tell you to take two weeks before you sign anything. The price will be the same.
Our Solar Battery Storage & Backup Services in Celina
Tesla Powerwall Installation
A Tesla Powerwall 3 installed in Celina runs $11,000-$16,500 before any federal tax credit. For most homes in the 75009 ZIP code, two Powerwalls are the right call if you want the air conditioner to keep running during a July storm. We handle the full CoServ application, the HOA documentation if your neighborhood requires it, and the programming so your battery actually does what you need it to do during peak windows.
Enphase IQ Battery Installation
If you already have Enphase microinverters on your roof, an Enphase IQ Battery is often the cleanest addition. A single 5P battery typically runs $4,800-$7,200 installed in Celina, and most homes we see add two or three. The advantage in Celina’s open prairie setting is the system’s granular control: you can run specific circuits during an outage without draining the entire battery running things you don’t need.
Whole-Home Backup Power
Whole-home backup in Celina means sizing for a 3,000-4,500 square foot two-story with two or three AC units. That’s a different animal than a partial backup that keeps your fridge and lights on. We design these systems so the transfer happens automatically in milliseconds, which matters when you’re away and a hail storm knocks out the grid. You come home and the power is on. The dog is fine. The freezer never thawed.
Battery Retrofit for Existing Solar
This is the work we do most in Celina. Homeowners bought solar between 2018 and 2022, the grid kept going down, and the panels sat dark because there was no storage. Retrofitting a battery onto an existing system is more complicated than adding one to a new install. The inverter has to be compatible. The rapid-shutdown code compliance has to be checked. And in Celina, the CoServ transformer capacity in your section has to be confirmed before you file anything. We’ve done enough of these retrofits in Mustang Lakes, Sutton Fields, and Light Farms to know where the traps are.

Trusted Brands We Service in Celina
We work with Panasonic, FranklinWH, Tesla, and Enphase battery systems, and we carry local stock so Celina homeowners aren’t waiting weeks for a part to ship from Houston. If your existing system runs Canadian Solar or JinkoSolar panels and the battery needs to tie into them, we handle that integration daily. We’re brand-agnostic in the way that matters: we’ll install what’s right for your roof, your CoServ bill, and your HOA’s rules, not whatever brand has the biggest spiff this quarter.
Common Solar Battery Storage & Backup Problems We See in Celina Homes
- CoServ interconnection delays. Installers who skip the informal transformer capacity check before submitting paperwork see applications sit for months. In Celina’s newest subdivisions, transformer capacity can be tighter than expected, and CoServ won’t approve an export system until it’s sorted.
- HOA placement violations. Celina HOAs routinely restrict battery units to side-yard placement or require screening. We’ve seen homeowners forced to relocate a permitted system because they installed it street-facing without checking. We review your HOA’s solar and battery language before we design anything.
- Pre-2020 solar systems missing rapid shutdown. If your Celina home had solar installed before the NEC 2017 rapid shutdown requirements became standard locally, you may need an inverter or microinverter retrofit before any battery can be integrated. We check this before we quote so there are no surprises mid-install.
- Sizing for CoServ’s peak window. CoServ’s time-of-use rates and demand charges mean a battery programmed for net-metering export often earns nothing. We program Celina systems for self-consumption during the co-op’s peak window, which is where the real bill savings come from.

FAQs - Solar Battery Storage & Backup in Celina
Yes, CoServ Electric permits whole-home backup with a Tesla Powerwall in Celina, but the interconnection application must be filed correctly with the co-op’s specific documentation, which is different from Oncor’s process used in Frisco and McKinney. CoServ approval timelines run longer than investor-owned utilities, and in the newest sections of Celina, transformer capacity checks can delay approval if not done early. We handle the entire CoServ filing for you. Call (877) 550-6892 and we’ll start the paperwork this week.
Most Celina HOAs allow Enphase IQ Battery installation, but many require the battery mounted on a side or rear wall rather than a street-facing elevation, and some require landscaping or a screen wall. Texas Property Code §202.010 prevents HOAs from banning solar outright, but battery placement is a gray area that varies neighborhood by neighborhood. We review your specific HOA’s covenants before we design anything. If your HOA is pushing back, call (877) 550-6892 and we’ll help you document what’s allowed.
CoServ’s buyback structure credits excess export at a lower rate than what you pay for consumption, which means simple net-metering payback math doesn’t work the same as it does in Oncor territory. In Celina, we typically program batteries for self-consumption during CoServ’s peak demand window so you avoid buying expensive co-op power at 4-7 p.m. on summer days. That programming choice can cut payback time roughly in half compared to a battery set up for export. For a Celina-specific payback estimate on your actual usage, call (877) 550-6892.
If your existing system predates the rapid shutdown requirements now enforced in Collin County, you’ll need an inverter or microinverter retrofit before any battery can be legally connected. This typically adds $1,500-$4,000 to the project depending on your current equipment. We identify this during our first site walk so the number on your quote is the number you pay. If a previous installer didn’t flag this, we’ll show you exactly what’s needed. Call (877) 550-6892 for a free site assessment in Celina.
Yes, an Enphase IQ Battery can power your air conditioner during a storm outage, but only if the system is sized correctly and the AC has a soft-start device installed. In most Celina homes with a single IQ Battery 5P, you’ll back up essential circuits like refrigerator, lighting, and a window unit, but not a 4-ton central AC. Two or three batteries with soft-start devices will run a modern HVAC system through a multi-hour outage. We’ll model your specific loads before we quote. Call (877) 550-6892 and ask for the whole-home load calculation.
Why Celina Homeowners Call Gus’s Solar First
Celina is served by CoServ Electric, a cooperative with its own interconnection paperwork, net-metering buyback structures, and approval timelines. That’s not Oncor like neighboring Frisco or McKinney. If your installer doesn’t know the co-op’s rules, your battery gets designed wrong and your application stalls. We know the rules because we’ve been doing this work in Celina’s master-planned communities long enough to see the rejections, the capacity shortfalls, and the HOA relocation fiascos. We design around all of it from day one.
In the Mustang Lakes subdivision, we retrofitted two Tesla Powerwalls onto an existing 11.2 kW Enphase system on a 2021 two-story with complex roof planes. The homeowner’s CoServ true-up statement showed a $0 credit but high summer demand charges. We programmed the batteries for self-consumption during the co-op’s peak window, and the annual bill dropped by an estimated 40% without any net-metering export. That’s the kind of detail work that doesn’t happen when an out-of-state crew installs a battery and drives away.
Celina’s housing stock is almost entirely post-2015 construction in master-planned communities. Large two-story homes with 3,000-4,500 square feet and multiple AC units. That means most homes need two batteries for real whole-home backup, and it means the HOA review matters as much as the CoServ review. We’ve done this enough to know exactly what both will ask for.
And the hail. Celina sits squarely in the North Texas hail corridor, which means power outages during storm season aren’t a hypothetical. They happen every spring. A battery that’s sized correctly and programmed for CoServ’s rates is the difference between sitting in the dark after a hail storm and keeping your family cool, your food cold, and your sump pump running. We build systems for Celina’s reality, not for a brochure.
If you’ve been burned by a national outfit that quoted one number on the phone and another at the door, you’ll find us different. We answer the phone. We show up when we say we will. And we stand behind the work with Gus’s name on it. Call (877) 550-6892 for a free, no-pressure estimate. Take two weeks to think about it. The price will be the same.
