Fast, Reliable Solar Battery Storage & Backup Across Farmersville

Adding a battery to your Farmersville home’s solar system usually costs between $9,500 and $16,500 before incentives, and for most homes we quote, the work can be scheduled within two to three weeks. We’re Gus’s Solar, and Gus Petrakis has been putting his name on every job since 2011. When you call (877) 550-6892 to talk about backup power for your home off Farmersville Blvd or over near Citrus Drive, a live person answers. Not a call center. That matters when your power is out and it’s 106°F outside.

Call (877) 550-6892

Farmersville is a town where we know the houses. We know the 1960s ranchers with one-car carports, the 1970s stuccos on small lots, and the roofs that have survived more Tule fog seasons than most installers in Visalia will ever see. That local knowledge changes how we size a battery, how we route conduit, and how we tell you what the system will actually do come January.

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

Gus started this company in 2011 and never handed the truck keys to a subcontractor. The crew that shows up at a house near Rose Avenue is his own crew, background-checked, uniformed, and trained on the same equipment we’d put on our own roofs. Farmersville homeowners tend to want one thing from a solar company: a name they can find again. Gus publishes his address, his license number, and his phone number, and he’s the one who calls you back if something isn’t right.

We answer calls from Farmersville all day and all night. A live person, 24/7. If a battery alarm goes off in the middle of the night, you don’t leave a voicemail and hope. You talk to someone who can start figuring out the problem. That’s the difference between a local owner-operated shop and a national outfit that sold you a contract and disappeared.

Our Solar Battery Storage & Backup work in Farmersville comes with the 90-Day Done Right Promise in writing. If it’s not right, Gus makes it right. One call brings him back.

Our Solar Battery Storage & Backup Services in Farmersville

Battery Retrofit for Existing Solar

This is the single most common job we do in Farmersville. A lot of homes here got solar between 2010 and 2016, back when NEM 1.0 and 2.0 made a panel-only system a no-brainer. Those older systems have inverters that are aging out, and their export rates are getting squeezed under NEM 3.0. Retrofitting a battery lets you store what you make instead of selling it to the utility for pennies. On a 1970s ranch near Farmersville Blvd, we pulled an original string inverter that had visible capacitor swelling, installed a SolarEdge Energy Hub with a Tesla Powerwall 2 backing up the main panel, and coordinated with our roofing partner to replace the south-facing slope before the array went back up. That customer’s true-up statement the following July showed a zero balance for the first time since 2016.

Whole-Home Backup Power

Farmersville summers regularly push past 105°F. Your AC runs constantly. When a heat wave knocks out a feeder line or a transformer, a whole-home backup system keeps your refrigerator, your AC, and your medical equipment running. We size these systems off your actual utility bill, not a brochure estimate. Bring us a bill, we’ll bring you the math.

Whole-Home Backup Power

Time-of-Use & NEM 3.0 Optimization

If you’re adding a battery under NEM 3.0 rules, the economics change completely. Export rates are low, so the battery’s job is to soak up midday solar and feed it back to your house during the 4 to 9 PM peak-rate window. We program your Tesla or Enphase system to match Southern California Edison’s time-of-use schedule for the Farmersville area, so the battery discharges when power costs the most. For homes in the 93223 zip code, this typically cuts the payback period by two to three years compared to a system that just runs in backup-only mode.

Tesla Powerwall Installation

We install and service Tesla Powerwall 2 and Powerwall 3 systems throughout Farmersville. A single Powerwall 3 stores 13.5 kWh, which covers lights, refrigeration, and a few hours of AC during an evening outage. Two Powerwalls back up a whole house, including central air, overnight during Tule fog season when solar production is near zero for days. We quote the year-25 output, not the day-one brochure number.

Enphase IQ Battery Installation

Homes with Enphase microinverters pair cleanly with Enphase IQ Battery 5P units. These are modular, so you can start with one and add a second later if your needs grow. For Farmersville homes with small roofs and shaded south faces, the Enphase ecosystem gives you per-panel monitoring that helps you see exactly which panels are producing and which aren’t during those thick December fog weeks.

Trusted Brands We Service in Farmersville

We work with equipment we trust to still be running in year 25. For Farmersville installs, that usually means Tesla Powerwall, Enphase IQ Battery, or FranklinWH aGate systems. We stock the common service parts for these systems locally, so a battery breaker trip or a communication fault doesn’t mean waiting a week on a shipment. We also take over service and maintenance on existing systems, even if we didn’t install them. If it’s got a label that says SolarEdge or a battery that’s stopped talking to the gateway, call (877) 550-6892 and we’ll come look.

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

  • Legacy string inverters dying during summer heat waves. A 2010-era inverter sitting on a west-facing wall in Farmersville heat can hit thermal shutdown in July. When it goes, your panels stop producing and your backup battery has no source. We replace these with modern hybrid inverters that pair directly with a battery.
  • Tule fog production collapse in December and January. Farmersville gets thick fog that can sit for two or three weeks. Solar production drops to near zero some days. If a battery is undersized, it drains by early evening and the house pulls from the grid at the highest winter rates. Honest first-year kWh projections matter more here than almost anywhere else in Tulare County.
  • Rapid shutdown compliance forcing roof work mid-project. Older Farmersville roofs with degraded composition shingles often can’t support the required rapid shutdown upgrades without a membrane replacement. This adds $4,000 to $7,000 and delays interconnection by two to three weeks. We tell you this before we start, not after we’ve opened the roof.
  • Undersized battery banks draining overnight with electric heaters or medical equipment. A single 13.5 kWh battery won’t run a space heater and a CPAP all night and still have anything left by morning. We size for your real loads, including the medical equipment some Farmersville households run throughout fog season.

Pricing for Solar Battery Storage & Backup in Farmersville, CA

A typical single-battery retrofit on an existing Farmersville solar system runs $9,500 to $12,500 before the 30% federal tax credit. That includes the battery, gateway, critical-loads panel, and labor. A whole-home backup system with two batteries and an upgraded main panel usually lands between $18,000 and $26,000. Roof remediation, if required, adds $4,000 to $7,000. Here’s the honest breakdown:

  • Tesla Powerwall 3 (13.5 kWh) installed, single unit: $11,000-$14,000
  • Enphase IQ Battery 5P (5 kWh) installed: $5,500-$7,500 per unit
  • FranklinWH aGate + aPower (13.6 kWh): $12,000-$15,500
  • Battery retrofit labor with main panel work, no roof issues: $2,500-$4,000
  • Roof remediation before remount (when required): $4,000-$7,000

Trusted by homeowners across Farmersville and surrounding areas.

★★★★★

"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."

Cassius Delacroix · Verified customer
★★★★★

"Gus's own crew did the install. Not a subcontractor who had never met him, which is what the big outfit quoted me and could not tell me who would actually be on my roof."
