Solar battery storage in Kirby, TX typically runs $11,500-$17,900 for a single battery install, and $9,800-$13,500 when retrofitted onto an existing array. Most Kirby homes we serve can be up and running within 3-5 business days after permits clear. We know the streets here, the panel upgrades most older houses need, and the CPS Energy interconnection process that ties it all together. Call (877) 550-6892 for a straight quote off your actual bill.

Kirby is its own little city tucked entirely inside San Antonio’s arms, and that quirk changes how battery jobs get permitted. We pull permits through Kirby’s own city hall, not San Antonio’s Development Services Department. Out-of-area crews routinely get that wrong, and the delay lands on the homeowner. It never does here, because Gus Petrakis has been hand-walking these applications since we started doing Solar Battery Storage & Backup work in the enclave.

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

Kirby homeowners have plenty of reasons to be skeptical of solar salespeople. That’s fine by us. Gus Petrakis puts his name on the truck, his phone number on the quote, and his own crew on the roof. When you call to ask about your battery, a live person answers. Day or night. Not a voicemail box, not a ticketing portal, and certainly not a call center in another state.

We’ve been locally owned since 2011, and the difference shows up in the details. It’s knowing that most houses east of Old Seguin Road still carry original 100-amp panels that need a service upgrade before a battery can pass inspection. It’s knowing that the CPS Energy interconnection queue moves differently for Kirby residents because of the dual-permitting path. It’s quoting a number and not changing it after the site visit. And it’s the 90-Day Done Right Promise in writing on every job: if it’s not right, Gus makes it right.

Kirby neighbors talk. We hear about it at the hardware store, at the post office on Agarita Avenue, at the little league fields near Friendship Park. That’s the kind of reputation we’ve built here, one battery install at a time, with background-checked and uniformed techs who treat your house like it’s on their own block. Because for a lot of us, it is.

Our Solar Battery Storage & Backup Services in Kirby

Tesla Powerwall Installation

A Tesla Powerwall 3 install in Kirby runs $13,500-$17,900 for the first unit, including gateway and integration with your existing or new array. These units hold 13.5 kWh of storage, which covers the essentials through a typical CPS Energy outage and then some. Given Kirby’s spot in Texas hail alley, we mount them in the garage or on a shaded east wall rather than the south-facing exterior, keeping them out of the worst storm paths.

Enphase IQ Battery Installation

Enphase IQ batteries run $11,500-$15,500 in Kirby for the 5P system, and because they’re modular, you can stack capacity as your needs grow. They pair cleanly with Enphase microinverters, which are common on the mid-century tract homes around the 78244 ZIP code. This is often the best first battery for a smaller, 1960s-era ranch on a tight lot, where a single 5 kWh unit covers the refrigerator, a window unit, lights, and the modem.

Whole-Home Backup Power

If you want to run the entire house during a CPS Energy outage, including the air conditioner, expect $22,000-$34,000 in Kirby for a two-battery setup sized to your actual load. That price includes the necessary 200-amp main panel upgrade if your home still has its original 100-amp service, which is more common here than in newer suburban builds. The humidity that settles over Kirby in August means whole-home cooling backup isn’t a luxury; it’s the primary reason people go bigger.

Battery Retrofit for Existing Solar

Already have panels? Adding storage runs $9,800-$13,500 in Kirby, with most quotes landing closer to the middle when no main panel upgrade is required. Retrofit work on Kirby’s smaller lots means we often use garage wall space creatively, and because so many homes here share nearly identical roof pitches and orientations from the original east-side tract developers, the site assessment moves fast. You’ll also want Solar Panel Cleaning in Kirby scheduled around the same time so your panels are performing at full output when the battery starts charging in earnest.

Trusted Brands We Service in Kirby

We install and service Tesla, Enphase, and FranklinWH battery systems, which covers the overwhelming majority of what’s already on Kirby roofs and what’s being quoted right now. Because we’re a local shop, we keep common replacement parts and firmware tools on hand, which means when a battery in the 78244 ZIP code throws an error code, we’re usually fixing it the same day rather than waiting on a shipment from California. We also maintain and expand existing systems, including adding a second battery to an existing FranklinWH or Tesla setup as your household’s load grows. If you’re adding an EV to the mix, pairing your battery with EV Charger Installation in Kirby makes a lot of sense: charge the car from stored solar overnight instead of pulling from the grid during peak CPS Energy rates.

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

  • 100-amp panel bottlenecks. A lot of Kirby homes were built between the late 1940s and the 1970s, and many still carry original 100-amp main panels. A battery can’t pass inspection when the service entrance is undersized, so a panel upgrade to 200-amp is a near-routine add-on cost we flag on the very first site visit.
  • Hail damage to inverters and disconnect boxes. Texas hail alley doesn’t just threaten glass, it also abuses the outdoor electronics on your solar setup. We see cracked disconnect enclosures and water intrusion in inverters after big spring storms through Kirby, and we check for those before any battery is tied in.
  • Faulty wiring from previous installers. Not every solar company that worked Kirby did the job to code. We regularly find undersized conductors and poorly torqued connections from earlier installs, particularly on homes where a national outfit came through with a door-knocker years ago. A battery retrofit is often when those issues come to light.
  • Inverter-to-battery communication failures. Older Enphase and SolarEdge inverters sometimes struggle to communicate with newer battery management systems, especially on Kirby’s original 1960s-era electrical layouts. We’re familiar with the exact firmware mismatches on these mid-century tract homes and can usually resolve them without replacing the whole stack.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"Told me straight that a battery did not make sense for how we use power and sold me the array without it. He talked himself out of a good deal of money that afternoon."

Reginald Pontefract · Verified customer
★★★★★

"He flashed every roof penetration properly and showed me the flashing before it went down. Three roof seasons on and not a drop anywhere."

Philomena Achara · Verified customer
★★★★★

"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."
