Fast, Reliable Solar Battery Storage & Backup Across Upland

If your Upland home loses power during a summer peak or a Santa Ana wind event, a solar battery keeps your refrigerator, medical equipment, and air conditioning running without skipping a beat. Battery backup in Upland typically costs between $8,500 and $18,000 installed depending on capacity and whether you’re adding it to an existing system. For an exact number built off your actual bill, call Gus Petrakis at (877) 550-6892. We’ll walk your roof, read your usage, and give you a straight answer.

Call (877) 550-6892

Upland sits on a slope, and that slope changes everything about how we design battery backup here. A home in San Antonio Heights at 91784 deals with winter shade from Mt. Baldy that a flat 91786 tract home never sees. A battery sized off a satellite estimate without a physical shade survey will under-produce. We don’t design that way. Our Solar Battery Storage & Backup team measures what’s actually on your roof, then builds the battery around your real production numbers.

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

Gus Petrakis founded this company in 2011, and his name is on the truck, the quote, and the building. Upland homeowners have been calling us because we answer the phone like a neighbor, not a call center. A live person picks up 24/7, including the night before a public safety power shutoff when you’re trying to figure out if your battery will hold. That matters here. Upland sits in the Pomona Valley where SCE has used PSPS events during high winds, and when you call at 9 p.m. on a Tuesday, you get Gus, not a voicemail.

We’ve worked on both sides of Foothill Boulevard: citrus-era estate homes up in 91784 and mid-century stucco tract houses down in 91786 and 91785. Each requires a different battery design approach. You won’t get a door-knocker pitch from us. The price quoted is the price charged, every job carries our 90-Day Done Right Promise in writing, and our background-checked crew does the install ourselves. We don’t hand your electrical panel off to a subcontractor and walk away.

Gus’s answer to any quote question is the same: bring me a bill, I’ll bring you the math. Take two weeks. Think about it. The price will be the same.

Our Solar Battery Storage & Backup Services in Upland

Tesla Powerwall Installation

A Tesla Powerwall 3 in Upland runs $11,000 to $16,500 installed for a single unit, including the gateway and load-side wiring. For foothill homes in 91784, we re-run the production estimate with a physical shade profile before we commit to placement. A Powerwall placed in a Canary Island palm shadow will cost you real winter output. We measure first, then mount.

Enphase IQ Battery Installation

Enphase IQ batteries make sense for Upland homes with existing microinverter arrays, especially tract houses in 91785 and 91786 where the roof line is simple and the electrical panel is accessible. Expect $9,000 to $14,000 for a 5P or 10T system depending on whether you’re pairing it with a system controller for whole-home backup or running it as a partial-home circuit. Our team handles the commissioning and monitoring setup so you can see your battery’s state from your phone.

Whole-Home Backup Power

Upland’s heat waves push air conditioning loads hard. A whole-home backup design has to account for what happens when both AC condensers, a pool pump, and a refrigerator all pull at once during a 105°F afternoon. We size for the worst hour of the year, not the annual average. For a typical 2,200-square-foot Upland home with two AC zones, a whole-home battery bank usually lands between $18,000 and $32,000 including hardware and panel work. That’s the honest range.

Battery Retrofit for Existing Solar

Adding a battery to an existing solar system in Upland runs $8,500 to $15,000 for most homes, depending on inverter compatibility and whether your current system needs a panel derate. Homes in the 91784 foothills with 1950s clay-tile roofs add complexity: the rapid shutdown wiring has to be routed carefully, and valley tile replacement has to be done right or the conduit seal fails. We’ve seen that exact failure. Our crew knows how to avoid it on the first pass.

Trusted Brands We Service in Upland

We install and service FranklinWH aPower systems, Panasonic EverVolt, and Canadian Solar’s EP Cube for Upland homeowners who want alternatives to the big two names. Parts availability in the Inland Empire means we can usually pull what we need without waiting on a slow freight shipment. If you already have a system from Tesla or Enphase, we service those too. No finger-pointing at the manufacturer; we diagnose it, source the part, and fix it.

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

  • Winter shade under-sizing in 91784: Mt. Baldy’s mass blocks morning sun up to 90 minutes longer on foothill rooftops than in flat south Upland. A battery sized off a satellite production model runs short during a winter outage, right when you need the backup most.
  • Retrofit wiring failures on clay-tile roofs: Older citrus-era estates often have clay or concrete tile. When a previous installer routed rapid shutdown wiring under a valley, replacing a cracked tile broke the conduit seal and took the inverter offline. We re-route and reseal properly.
  • NEM 3.0 banks sized off flat-land estimates: South Upland tract homes on NEM 3.0 sometimes get a battery bank calculated from a standard Inland Empire production curve that ignores San Gabriel shading. Their true-up shows a 30% kWh shortfall. We build the model off your actual roof, not a regional average.
  • Heat-wave load spikes tripping the system: An older pool pump and two 20-year-old AC condensers pulling simultaneously can trip a whole-home backup that was never designed for Pomona Valley peak loads. We test for locked rotor amps and add a soft starter when needed.

Pricing for Solar Battery Storage & Backup in Upland, CA

Here’s the straight math for Upland. A single battery retrofit on a south Upland tract home starts around $8,500. Mid-range Enphase or FranklinWH installs with whole-home backup land between $12,000 and $18,000. A two-battery Tesla Powerwall system for a large foothill estate in 91784 runs $22,000 to $32,000 depending on panel work and whether you need a companion sub-panel for critical loads. What moves the number: roof type, shade profile, electrical panel condition, and whether your local SCE service requires a main panel upgrade. We quote the year-25 output, not the day-one brochure number.

Call (877) 550-6892 and bring us a recent SCE bill. We’ll give you a free estimate with the battery sized to your actual usage. Estimates are free, and no signature is wanted tonight.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"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."

Aurelia Santibanez · Verified customer
★★★★★

"He modelled it on my actual bill and the current export rates rather than the old ones, and told me plainly that the payback was longer than the door knockers had claimed. Then it came in about where he said it would."

Octavius Redmond · Verified customer
★★★★★

"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."
