Fast, Reliable Solar Battery Storage & Backup Across Selma

Solar battery storage in Selma, TX typically runs between $9,500 and $16,500 after the federal tax credit, depending on whether you’re adding a single battery or a whole-home setup. Most Selma homeowners call us because their grid-tied solar produces plenty of power in July but leaves them dark the moment CPS Energy or a storm takes down the line. We install, retrofit, and service battery systems across Selma’s older ranch neighborhoods, and we can usually have a quote in your hands within 48 hours. Call (877) 550-6892 if you want to talk through your options with someone who actually answers the phone.

Selma sits right in the path of Texas summer thunderstorms and the occasional winter ice event. When the power goes out, it doesn’t care that you already paid for solar panels. A battery changes that equation. We’ve been working on Selma homes long enough to know which 1970s-era panels need upgrading before a battery can even be permitted, and which retrofit routes save you the most money. That local knowledge is the difference between a system that works on paper and one that works when you need it.

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

Gus Petrakis put his name on this company in 2011, and he still answers his own phone. That matters in Selma, where homeowners have seen plenty of out-of-town crews roll through, slap panels on a roof, and disappear the first time something underperforms. Our customers around Schertz and Universal City know the difference. A live person picks up when you call, and Gus’s own background-checked crew does the install work, not a subcontractor we’ve never met.

We’ve built our reputation in the San Antonio metro by being straight with people. Bring us your CPS Energy bill and we’ll build the math off your actual usage, not a brochure estimate. If a battery doesn’t pencil out for your home, we’ll tell you that before we ever take a deposit. That’s why Selma homeowners keep our number saved in their phones. The 90-Day Done Right Promise means if something isn’t right, Gus makes it right. In writing, on every job.

We coordinate scheduling from our San Antonio office, and our crews serve Selma locally. Response time to most Selma neighborhoods is same-day for service calls and under 48 hours for new battery quotes. When a homeowner near the Retama Park area called us about a battery that stopped charging during a foggy week, we had a technician there the next morning. That’s how we operate.

Our Solar Battery Storage & Backup Services in Selma

Tesla Powerwall Installation

The Tesla Powerwall remains the most requested battery for Selma homes, and for good reason. It’s a 13.5 kWh unit that handles whole-home backup in most single-story ranch layouts, especially when paired with a second unit. We install Powerwall 3 systems regularly across Selma’s 93662 zip code, and we size the battery against your actual evening usage, not a generic square-footage formula. If your AC condenser is older, we’ll tell you what a single Powerwall can realistically carry before you spend the money.

Enphase IQ Battery Installation

Enphase IQ Battery 5P systems are a strong fit for Selma homeowners who already have Enphase microinverters on the roof. The modular design means you can start with one 5 kWh unit and add capacity later without rewiring everything. We’ve installed these on homes near Selma City Park and along Evans Road, and the flexibility works well for homeowners who aren’t sure yet whether they’ll go whole-home or partial backup. The 5P also runs quieter than many competing units, which matters when the battery hangs on a garage wall next to a bedroom.

Whole-Home Backup Power

Whole-home backup in Selma means sizing a battery system to carry your air conditioner, refrigerator, lights, and well pump if you’re on one of the outer properties toward Cibolo. Most Selma ranch homes need at least two batteries, sometimes three, to keep a 3-ton AC compressor running through a summer outage. We’ll look at your panel, your utility usage history, and your actual cooling load before we recommend a number. That’s the only honest way to do it.

Battery Retrofit for Existing Solar

This is the service we do more than any other in Selma. Homeowners bought grid-tied solar years ago, before battery prices dropped, and now they want backup. The good news is that most existing systems retrofit cleanly. The challenge in Selma is the electrical service: a high percentage of homes here still run on original 100-amp panels, which means the utility won’t approve the battery interconnection until the service is upgraded. We handle that upgrade as part of the retrofit, and we’ll show you the line item for it so there’s no sticker shock. A typical 200-amp service upgrade in Selma runs $2,800 to $4,200, depending on the meter location and whether your panel is flush-mounted in a wall.

Trusted Brands We Service in Selma

We work with the battery and inverter brands Selma homeowners ask for by name: Tesla, Enphase, FranklinWH, and SolarEdge among them. We stock common replacement parts and firmware updates locally through our San Antonio hub, which means faster turnaround when a Selma system needs service. If you already have a SolarEdge inverter and want to add a FranklinWH aPower battery, we’ll design it so everything communicates properly. No brand evangelism, just straight recommendations based on what works for your roof, your panel, and your usage pattern. Call (877) 550-6892 and we’ll talk through which direction makes sense for your home.

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

• Battery won’t charge during winter low-production stretches. Selma’s position in the San Antonio corridor means shorter winter days and occasional multi-day cloud cover. Homeowners with systems sized only for summer peak sun discover their battery never reaches full charge in January, leaving them without backup exactly when an ice storm threatens. We model annual production averages, not July numbers, when we size batteries for Selma homes.
• NEM and time-of-use settings draining the battery at the wrong time. If your battery is exporting stored power to the grid at 2 p.m. instead of holding it for the 4 to 9 p.m. peak window, you’re losing real money every single day. We see this constantly on systems installed by out-of-state companies that never came back to commission the settings properly. A settings correction alone often recovers hundreds of dollars per year on a Selma electric bill.
• Thermal derating on 105°F afternoons cutting solar production below what the battery needs. Selma summers are brutal, and when panel surface temps hit 160°F or higher, production drops 15 to 20 percent. That means your battery may not reach full charge before the evening peak on the hottest days, forcing your home to pull from the grid at premium rates. We account for this derating curve when we size your array and battery together.
• Original 100-amp panels blocking battery interconnection. Selma’s housing stock skews toward 1950s through 1980s ranch homes, and many still carry the original electrical service. The utility simply won’t approve a battery installation until the panel is upgraded to 200 amps. We surface this early in the quote process so you’re not blindsided by a permit rejection later.
