Fast, Reliable Solar Battery Storage & Backup Across Loomis
Solar battery storage in Loomis typically runs $12,500-$19,800 before incentives for a whole-home system, and most installations are completed in one to two days. The right battery keeps your well pump, AC, and lights running when PG&E cuts power, which happens more often out here than people expect. Gus’s Solar has been wiring backup systems for Loomis ranchettes and custom homes long enough to know exactly what these properties demand. Call (877) 550-6892 and we’ll look at your actual usage before quoting a single number.
Why Gus’s Solar Is Loomis’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis puts his own name on the truck and stands behind every battery job with a written 90-Day Done Right Promise. If something isn’t right, one call brings Gus back. That’s not a slogan; it’s how a locally owned shop operates when the owner lives in the community and answers his own phone around the clock.
Loomis homeowners tell us the same thing repeatedly: they’re tired of national outfits that quote one number on the phone and a different one at the door. We quote off your actual PG&E bill, itemize the equipment by brand and model, and hand you the math to take home. Take two weeks. Think about it. The price will be the same. If a salesman needs an answer tonight, the answer is no, and that rule doesn’t change when you call us.
Our response time to Loomis is same-day for emergencies and typically within 48 hours for standard battery service calls. Gus’s own crew does the install, background-checked, uniformed, and trained on the specific equipment going on your wall. No subs, no handoffs, no disappearing after the paperwork clears.
For Loomis specifically, that local presence means we know King Road, Taylor Road, and the ranchette parcels off of Swetzer and Val Verde. We know the tile roofs from the 1980s, the ground-mount possibilities on five-acre lots, and the private wells that change how a battery needs to be sized.
Our Solar Battery Storage & Backup Services in Loomis
Tesla Powerwall Installation
The Tesla Powerwall 3 is the most common battery we install in Loomis, and for good reason: its surge capacity handles the inrush current of a 240V well pump without tripping internal breakers. On ranchette properties where that well is the difference between a functioning home and a dead one during an outage, that single spec matters more than any brochure number. We handle the full installation, including the backup panel wiring and PG&E interconnection paperwork, and we can also help if you need EV Charger Installation in Loomis.

Whole-Home Backup Power
Whole-home backup in Loomis means something different than it does in Rocklin or Roseville. Here you might be backing up a 3,200-square-foot custom home, a detached shop, an irrigation controller, and a well pump all on the same system. We size the battery and configure the backup panel to prioritize the loads that matter most to you. When PG&E’s public safety power shutoffs hit the foothills, a properly wired whole-home system keeps your water running and your shop door opener live. Our full Solar Battery Storage & Backup team walks every Loomis job through a load audit before quoting, because guessing at battery sizing on these properties is how you end up with a system that browns out on day one.

Battery Retrofit for Existing Solar
Plenty of Loomis homes went solar between 2015 and 2021, before batteries made sense for most people. Under NEM 3.0, a retrofit changes the equation: without storage, your exported power buys you very little. With a battery, you cycle stored solar during peak PG&E evening rates instead of paying them. We retrofit Tesla Powerwall 3, Enphase IQ Battery 5P, and FranklinWH aPower systems onto existing arrays, matching the battery to your current inverter architecture. A retrofit on a Loomis home with an aging Enphase or SolarEdge system usually runs $11,000-$16,500 depending on battery count, panel upgrades, and whether you also need Loomis Solar Panel Repair.

Time-of-Use & NEM 3.0 Optimization
PG&E’s time-of-use rates punish homes that export solar at noon and import at 7 PM. A battery configured correctly flips that pattern. Our team programs the system to charge from excess solar during the day and discharge during peak-rate windows, which on current Loomis rate schedules saves real money every month. The configuration is specific to your rate plan, your battery, and your household’s actual consumption curve, all three of which we pull directly from your utility data. Loomis homeowners on NEM 3.0 almost always see faster payback with this setup than with solar alone.

Trusted Brands We Service in Loomis
We install and service batteries from Tesla, Enphase, FranklinWH, and Panasonic, every one backed by manufacturer warranty and our own 90-Day Done Right Promise. When a Loomis customer’s battery throws a fault code, we don’t route them through a call center in another state; we send a tech who carries the diagnostic tools and common replacement parts for the brands listed on our trucks. That same crew handles Solar Panel Maintenance & Monitoring in Loomis. That’s the difference between a battery down for a week and a battery back online the same day.
Common Solar Battery Storage & Backup Problems We See in Loomis Homes
- Battery tripping during outage because the well pump wasn’t factored in. A 240V submersible pump can pull 3-5x its running amps for a split second on startup. Undersized batteries or misconfigured backup panels trip their internal breakers right when you need water. We test inrush current on every Loomis install before finalizing the battery spec.
- Tile roofs from the 1980s through 2000s not assessed for load capacity. Older tile on custom Loomis builds can have cracked or shifted pieces, and mounting racking over compromised tile leads to leaks and microinverter failures. If the roof isn’t sound enough, we recommend a ground-mount, and we’ll tell you that before you spend a dollar.
- Time-of-use misconfiguration draining the battery at the wrong hours. A battery that discharges at 2 PM and charges at 6 PM is worse than no battery at all under NEM 3.0. We see this on systems installed by out-of-town crews who never checked the homeowner’s actual rate schedule.
- Detached shop and outbuilding loads left off the backup panel. If your shop’s fridge, door opener, or compressors aren’t wired into the backed-up circuits, you’ll find out during the first real outage. We map every Loomis property’s full electrical inventory before the install, not after.
Pricing for Solar Battery Storage & Backup in Loomis, CA
Here’s honest Loomis pricing, straight up. A single Tesla Powerwall 3 with installation and backup panel work runs $12,500-$16,900. Two Powerwalls for a larger ranchette with a well pump and detached shop falls between $22,000 and $29,500. An Enphase IQ Battery 5P retrofit onto existing Enphase solar typically lands at $9,800-$13,200 for the first unit. FranklinWH aPower systems, which some Loomis homeowners prefer for their expandability across multiple outbuildings, start around $13,500 and climb based on stack size. What changes your number: battery count, whether you need a new backup panel or subpanel, roof condition and mount type, and any main-panel service upgrade. Bring us a bill, we’ll bring you the math, and the quote includes everything spelled out. Free estimate, no signature wanted tonight. Call (877) 550-6892 for exact numbers on your Loomis property.
How Loomis’s Elevation Changes Your Battery Payback
Loomis sits at roughly 400-600 feet of elevation, high enough to escape most of the Tule fog that blankets Roseville and Rocklin just 10-15 miles west from November through February. That fog doesn’t just reduce solar production on the valley floor; it murders winter generation precisely when those homes need it for battery charging. Winter is when PG&E outages hit hardest, and a battery that never gets a full charge in December is a paperweight. Loomis homes see meaningfully more winter sun hours than valley-floor neighbors, which means batteries here recharge fully on short winter days and hold through the night far more dependably. If you run the payback numbers, that winter generation difference shortens your break-even by months, not years.
Then add the well pump. Most Loomis parcels on the ranchette side of town run private wells on 240V submersible pumps, and that’s a year-round base load that keeps your system producing and cycling every single day. A home that uses power constantly for water is a home where solar and storage pencil out faster, because there’s no seasonal dead zone. Irrigation, shop tools, freezers, a second fridge in the garage: the loads on these properties are heavier and more consistent than on a 1,600-square-foot Roseville tract home, and that changes the math in your favor.
On a ranchette off King Road, our crew installed a Tesla Powerwall 3 paired with an Enphase IQ system for a 1980s custom home running a 240V well pump and a detached shop. Because the roof had tile in fair-to-poor condition, we placed the array on a ground-mount with a 215° azimuth, then wired the whole-home backup panel to keep the well, irrigation controller, and shop door opener live during PG&E outages. That’s the kind of job you only get right if you’ve been doing Loomis work long enough to check the roof honestly and know when a ground-mount is the better call. Our Solar Battery Storage & Backup crew does this every week, not once a season.

FAQs - Solar Battery Storage & Backup in Loomis
Yes, if the battery is sized correctly for the pump’s inrush current and the pump circuit is wired into the backup panel. A 240V submersible well pump can momentarily pull 3-5 times its running amps on startup, and undersized batteries trip their internal breakers at exactly the wrong moment. We test every Loomis well pump’s actual draw before finalizing your battery spec, and we wire the well circuit into the backed-up loads so your water keeps running when the grid drops. If you’re not sure whether your current or planned battery can handle your pump, call (877) 550-6892 and we’ll check it for free.
Yes, and under NEM 3.0 it’s usually the smartest move a Loomis solar owner can make. Without storage, the excess power you export midday earns pennies, while the power you import at 6 PM costs peak rates. A retrofit battery cycles your stored solar during those expensive evening hours, which is where the payback comes from. We install Tesla Powerwall 3, Enphase IQ Battery 5P, and FranklinWH aPower onto existing systems, matching the battery to your current inverter brand. Retrofits in Loomis typically run $9,800-$16,500 before incentives depending on battery size and panel work. Call (877) 550-6892 and we’ll run your actual NEM 3.0 numbers.
Most Loomis ranchettes need a minimum of 13.5 kWh of storage, which is one Tesla Powerwall 3, and many need two once you add a well pump, irrigation controller, detached shop, and large custom-home footprint. The deciding factors are your well pump’s startup draw, whether you want the shop backed up, and how long you expect to run without PG&E. A single Powerwall 3 will run essential loads (well, fridge, lights, one HVAC zone) for 12-24 hours depending on usage. A two-battery system can carry most whole-home ranchette loads through a multi-day outage. We itemize your actual loads before quoting, so you’re not guessing.
Loomis sits at 400-600 feet elevation, above the Tule fog that sits on Roseville and Rocklin through the winter months. That means your panels produce real power in December and January, when valley-floor systems are scraping by. A battery only earns its keep if it can recharge daily, and a fogged-in array won’t do that. Loomis’s winter generation advantage means faster battery payback, more outage resilience in the season when outages matter most, and a system that actually cycles year-round instead of going dormant for two months. In practical terms, Loomis homeowners typically see 18-24 months shorter payback on battery storage than their valley-floor counterparts.
Not always, but more often in Loomis than in the denser suburbs downhill. Many Loomis homes have tile roofs from the 1980s-2000s that are reaching the end of their structural lifespan, and mounting racking over compromised tile causes leaks and attachment failures. If your roof is in fair-to-poor condition, a ground-mount on your acreage is often the better and cheaper long-term call, and it lets you angle the array for optimal winter production, which matters for battery charging. We’ll tell you honestly which option fits your property, and we won’t sell you a roof-mount just because the crew is already scheduled. Call (877) 550-6892 for a straight answer on your roof.
