AfterFast, Reliable Solar Battery Storage & Backup Across Winters
If your power goes out in Winters, a solar battery keeps your refrigerator cold, your well pump running, and your lights on. We install and service battery backup systems throughout the 95694 ZIP code, from the Victorian homes downtown to the ranch properties off Highway 128. Gus Petrakis founded this company in 2011 and has built it on one rule: do the job right, quote honestly, and answer the phone when you call. That phone number is (877) 550-6892, and a live person picks up 24/7. Not a voicemail. Not a call center. A person who knows Winters.
Most battery storage and backup projects in Winters run between $9,500 and $18,500 after incentives, depending on whether you need a panel upgrade, a retrofit to existing solar, or a whole-home backup system. But before you sign anything, bring us a bill. We’ll show you the real year-25 numbers off your actual utility statement, not a brochure estimate.
Why Gus’s Solar Is Winters’s Preferred Solar Battery Storage & Backup Company
We’re not a pop-up sales crew working Winters from a rented booth at the farmers market. Gus’s Solar has been locally owned and operated since 2011, with a published address, a state license, and an owner whose name is on the truck. Gus Petrakis answers his own phone. When you call about a battery system for your home on Main Street or an orchard parcel out on Putah Creek Road, you’re talking to the person who makes the decisions, not a scheduler reading from a script.
Our Solar Battery Storage & Backup team has spent years working on Winters homes, and that local familiarity matters more than most people realize. We know which downtown Victorians still have 100-amp panels that the utility will reject on an interconnection application. We know the tule fog patterns that suppress solar production from December through February. We know the PG&E agricultural rate structures that farm accounts in 95694 deal with. Those details change the sizing math, and they change the payback.
Every job carries our 90-Day Done Right Promise in writing. If it’s not done right, Gus makes it right. One call brings him back. And our background-checked, uniformed crew does the install. We don’t hand your battery project to a sub. Gus’s name is on the work.
Our Solar Battery Storage & Backup Services in Winters
Battery Retrofit for Existing Solar
If you already have solar panels on your Winters home, adding a battery is usually straightforward and far cheaper than starting over. We’ve done many retrofits across Winters, including a recent Enphase IQ Battery install on a 1970s ranch house downtown where the original 100-amp panel had to be upgraded to 200 amps to pass interconnection. The homeowners wanted whole-home backup for summer AC loads and winter outage coverage, so we prioritized backup during PG&E’s evening peak and set the system to export only when the battery was full. Their true-up statement dropped dramatically. Panel swap and battery install were done in one day, without tearing up their landscaping.
Time-of-Use & NEM 3.0 Optimization
Winters sits in PG&E territory, and NEM 3.0 changed the economics of solar in a big way. Under the old rules, you could sell excess power back at near-retail rates and rely on the grid as your battery. Those days are over. Now the export rates are much lower, which means a battery that shifts your solar production into the evening peak is no longer optional. It’s how you avoid paying top dollar for grid power every evening. We run the math off your actual bill and size the battery to cover your real evening load, not a generic formula.
Whole-Home Backup Power
When the power goes out in Winters, it’s usually during a summer heat wave, a winter storm, or wildfire-related public safety power shutoffs. A whole-home battery system keeps your AC, well pump, refrigerator, and medical equipment running without interruption. For rural properties on the edge of town along Russell Boulevard or out toward the orchards, this matters even more. You might be the last house on the circuit to get restored, and a working battery means you don’t care. We size whole-home systems by looking at your actual panel load and the equipment you can’t live without.
Tesla Powerwall Installation
The Tesla Powerwall remains the most requested battery in Winters, and we install a lot of them. Each Powerwall 3 unit stores 13.5 kWh, and most Winters homes need one or two units depending on AC load and whether you have a well pump. We can integrate Powerwall with existing solar from any major brand, and the Tesla app gives you straightforward control over backup reserve and time-of-use settings. On farm properties with irrigation pumps, two Powerwalls paired with load management makes a meaningful dent in demand charges.
Enphase IQ Battery Installation
For homes with Enphase microinverters already on the roof, the Enphase IQ Battery is often the cleanest add-on. The system talks to itself natively, which means simpler monitoring and fewer communication headaches. We’ve put IQ batteries on mid-century ranch houses and newer tract homes across Winters, and the modular design lets you start smaller and add capacity later if your needs grow. That flexibility matters for homeowners who buy an EV or add a pool pump down the road.
Battery Replacement & Expansion
Batteries don’t last as long as panels. If your existing battery is aging out or you want to add capacity to cover more of your home, we handle replacement and expansion. We work with FranklinWH, Panasonic, Tesla, and Enphase systems, and we stock common parts so a Winters service call doesn’t mean waiting a week for a shipment from out of state. You tell us what’s failing or what’s not keeping up, and we fix it in one trip when possible.

Trusted Brands We Service in Winters
We install and service batteries from Tesla, Enphase, FranklinWH, and Panasonic, and we integrate them with solar arrays built on Canadian Solar, Qcells, REC, SolarEdge, and other major brands. If you already have a system and you’re not sure what’s compatible, call us. We’ll look at your equipment and tell you straight what works and what doesn’t. We don’t push a brand because we get a better margin on it. We recommend what fits your Winters home, your panel, and your budget.
Common Solar Battery Storage & Backup Problems We See in Winters Homes
- Undersized 100-amp panels blocking battery permits. Many downtown Winters Victorians and Craftsman homes still run on 100-amp service, and PG&E will reject an interconnection application for a battery unless the panel is upgraded. We handle the panel swap as part of the battery install so you don’t get stuck in permit limbo.
- Batteries sized with Sacramento solar data, not Winters tule fog data. The dense radiation fog that settles over the valley floor from December through February cuts production significantly. If your installer doesn’t account for it, your battery won’t recharge fully during winter outages. We build fog-adjusted yield estimates into every quote.
- Farm accounts quoted without demand charge analysis. Winters has real agricultural customers on PG&E Schedule AG rates, which carry demand charges. A battery sized only for evening load-shifting will underperform for these properties. The battery needs to target peak irrigation and processing loads to actually cut the bill.
- Battery systems that don’t talk to existing inverters. Mixing brands without planning leads to communication failures, error codes, and service calls. We check compatibility before we quote anything, and we don’t sell you a system that’s going to argue with itself.
Pricing for Solar Battery Storage & Backup in Winters, CA
Here’s the straight math for Winters. A single Tesla Powerwall 3 installed typically runs $11,000 to $14,500 before incentives. An Enphase IQ Battery system for a standard home runs $9,500 to $13,000. Whole-home backup with two batteries and a critical loads panel runs $18,000 to $26,000. If your panel needs an upgrade from 100 to 200 amps, add $2,800 to $4,500. Farm accounts with demand charge management and load control equipment run higher because of the extra hardware and programming.

FAQs - Solar Battery Storage & Backup in Winters
Tule fog cuts daily solar production in Winters by 30 to 50 percent from December through February compared to summer, which means your panels may only produce 2 to 3 usable hours of charging on the worst days. If your battery is sized without accounting for this, it won’t recharge fully during a multi-day winter outage. We build fog-adjusted production estimates into every Winters quote so your backup system actually works when the grid is down and the fog is thick. Call (877) 550-6892 to see what your system would produce in December, not just in July.
Yes, ground-mount arrays on Winters agricultural parcels integrate well with battery storage, and in many cases they’re the better site for it. The key difference for farm accounts is that PG&E agricultural rate schedules carry demand charges, which means your battery should be programmed to shave peak irrigation and processing loads, not just shift evening energy. We’ve worked on orchard and olive grove properties around 95694, and we size the battery to your actual pump schedule and utility tariff. Call us for a demand charge analysis before you buy anything.
Most homes in Winters built before 1990 run on 100-amp panels, and yes, you’ll probably need an upgrade to 200 amps before PG&E will approve your battery interconnection. The upgrade typically costs $2,800 to $4,500 and adds one day to the project. We include the panel work in our battery quotes so you’re not surprised by a change order halfway through. The downtown Victorians and older Craftsman homes are the most common candidates for this work.
Under NEM 3.0, the export rate for excess solar has dropped significantly from what it was under NEM 2.0, which means sending power back to the grid at noon and buying it back at 7 p.m. is a losing trade. A battery that stores your daytime production and uses it during PG&E’s evening peak typically adds $600 to $900 per year in avoided grid charges for a standard Winters home, and more if you’re on a rate plan with steep evening differentials. For farm accounts on demand-charge rates, the savings can be substantially higher. We run the payback math on your actual bill, not a generic example.
In most cases, yes. For a standard whole-home battery install on a rural Winters property, our crew arrives with the batteries, the critical loads panel, the wiring, and everything needed to complete the job in one day. The main exception is when a panel upgrade is required, which may add a second day depending on the electrical work involved. We coordinate with the utility ahead of time so you’re not waiting weeks between the battery install and permission to operate. Call (877) 550-6892 and we’ll give you a realistic timeline for your specific property.
