Fast, Reliable Solar Battery Storage & Backup Across Boerne

If you live in Boerne and want a solar battery that actually keeps your lights on when the grid drops, here’s the straight answer: a properly sized and GVEC-interconnected battery backup system in Boerne runs $12,000 to $18,500 before the federal tax credit, and the biggest variable is not the hardware. It is whether the installer knows Guadalupe Valley Electric Cooperative’s paperwork. Most Boerne homes we see were built after 2010 with 200-amp panels, which speeds up installation considerably. If your panel is older, we’ll tell you before we quote, not after. Call (877) 550-6892 and tell us what you’re trying to keep running. We’ll give you a straight answer.

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

Gus Petrakis has owned Gus’s Solar since 2011. He works the Hill Country the same way he always has: his name is on the truck, his phone number is published, and when something goes wrong, he is the one who shows up. That matters in Boerne, where homeowners tell us every week about another San Antonio outfit that quoted a battery, filed nothing with GVEC, and disappeared. We do not do that. Our Solar Battery Storage & Backup team handles your GVEC interconnection before we ever schedule the install, so you are not sitting with a finished battery waiting weeks for an inspection.

Boerne homeowners call us from Esperanza, the newer master-planned streets of 78015, the older ranch-style neighborhoods of 78006, and everywhere along Highway 46 and IH-10. We know these neighborhoods. We know which HOA review boards in Boerne restrict wall-mounted battery enclosures to specific elevations and which will approve a garage install without a committee meeting. We know the limestone. We know GVEC. And we answer the phone 24/7, with a live person. Not a voicemail, not a ticket queue. Call us at (877) 550-6892 and you’ll get exactly that.

Every job we do in Boerne carries the 90-Day Done Right Promise: if it is not right, Gus makes it right, in writing. No fine print. No “that’s a warranty issue” runaround. Gus’s own background-checked, uniformed crew does the install. He does not hand your battery to a subcontractor he met once. When a Boerne homeowner calls with a battery question six months after install, Gus is the one who picks up.

Our Solar Battery Storage & Backup Services in Boerne

Tesla Powerwall Installation

Boerne homeowners who want whole-home backup in an outage consistently land on the Tesla Powerwall 3. It handles the weight of Hill Country summer loads, including two AC units, and it integrates directly with GVEC’s interconnection framework. A Tesla Powerwall installation in Boerne typically runs $10,500 to $13,000 per unit before any other electrical work. We handle the GVEC battery export application before the first day on site. That alone saves Boerne homeowners weeks.

Enphase IQ Battery Installation

The Enphase IQ Battery 5P is the practical choice for Boerne homes that already run Enphase microinverters, which are the majority of post-2015 installs in Kendall County. When we install an Enphase battery in Boerne, we map your existing microinverter layout and confirm whether your home’s panel can accept the IQ System Controller. A single IQ 5P install in Boerne runs $6,500 to $8,200; most Boerne homes we see pair two or three units for real backup coverage. The advantage here is native compatibility with your existing Enphase monitoring, so you see battery state of charge and home load on one screen.

Whole-Home Backup Power

In Boerne, whole-home backup means keeping your well pump, refrigerators, medical equipment, and at least one HVAC zone running through a Hill Country outage. We size these systems from your actual GVEC usage statements, not a brochure estimate. A whole-home backup system for a typical Boerne 2,800-square-foot home, including two to three batteries and the necessary gateway, runs $24,000 to $34,000 before the federal tax credit. Gus quotes the year-25 output on these systems, not the day-one brochure number. Bring us a bill, and we’ll bring you the math.

Battery Retrofit for Existing Solar

This is the most common request we field in Boerne. Homeowners installed solar five, eight, ten years ago, before battery economics made sense here. Now GVEC’s buyback terms, the wild weather, and the hail-season outages have changed that. Adding a battery in Boerne runs $11,000 to $16,500 for a single-unit retrofit, depending on whether your existing inverter architecture is AC-coupled or needs a gateway swap. We have retrofitted batteries onto systems from Enphase, SolarEdge, and older SunPower arrays throughout Boerne’s 78006 and 78015 ZIP codes. We know the integration points. We know the gotchas, especially the older 100-amp panels in the original 78006 neighborhoods near the historic downtown.

One more thing worth stating plainly. If a solar salesman is pressuring you to sign a battery contract tonight, in Boerne, the answer is no. Take two weeks. Think about it. The price will be the same. Anyone who needs an answer tonight is not the contractor you want inside your home’s electrical panel.

Trusted Brands We Service in Boerne

We work on and install Tesla, Enphase, SolarEdge, SunPower, Panasonic, Qcells, REC, Canadian Solar, JinkoSolar, and FranklinWH equipment. For Boerne specifically, we keep FranklinWH and Tesla battery inventory locally accessible, so a warranty swap or expansion does not mean waiting on a distributor two states away. If you bought a SunPower system and your original installer has gone quiet, call us. We service what others walked away from.

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

  • Battery installed, but GVEC never approved the interconnection. This is the single most common failure we see in Boerne. A battery sits on the wall, panels produce power, but nothing exports and the backup gateway is disabled until GVEC inspects. The homeowner is told “it takes a while.” It does not, if the paperwork was filed correctly before the install. We file GVEC’s battery-specific export application as step one, not step four.
  • A battery sized for San Antonio net-metering, not Boerne’s GVEC reality. San Antonio assumptions leak into Boerne quotes all the time. GVEC’s buyback rate changes the math. A battery sized for full-home backup when the homeowner only needed solar self-consumption leaves them with a bigger system than they needed and a longer payback. We size batteries from your actual GVEC true-up statement, not a generic Texas average.
  • Retrofit on an older 78006 home without checking the 100-amp breaker. The mid-century and 1980s homes near old downtown Boerne often still run 100-amp mains. When a battery gateway tries to pass through on a 100-amp panel, the main breaker can trip the moment grid power returns. We call it a blackout after the blackout. We check panel rating before we quote, always.
  • Battery enclosures that fail Boerne HOA review. Newer Boerne subdivisions with architectural review boards in 78015 often restrict wall-mounted battery enclosures to specific elevations or require them screened from the street. We have worked with the common Boerne HOAs and know which enclosures pass, where to place them, and what paperwork the board expects. A San Antonio installer who has never dealt with a Boerne HOA can lose two months to a review committee.

Pricing for Solar Battery Storage & Backup in Boerne, TX

Here are the numbers we actually quote in Boerne, not a national average table. A single Tesla Powerwall 3 install runs $10,500 to $13,000. An Enphase IQ 5P starts around $6,500 for the unit install when it integrates cleanly with existing Enphase microinverters. A whole-home backup build for a Hill Country 2,800-square-foot home with two or three batteries lands between $24,000 and $34,000. Battery retrofits on existing solar in Boerne run $11,000 to $16,500 depending on which inverter platform you have and whether we need to add a backup gateway. The federal Investment Tax Credit covers 30% of battery systems installed in 2026, and we prepare that documentation as part of the job. Your actual price comes from your GVEC bills and your home’s electrical panel. Bring us a bill, we’ll bring you the math. There is no charge to come out to Boerne, and there is no trip charge inside our own county, which includes Kendall County. Call (877) 550-6892 and ask for a free estimate. The number you see is the number you pay.

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."
