AfterFast, Reliable Solar Battery Storage & Backup Across Dixon
Solar battery storage in Dixon typically runs $9,500-$16,500 before incentives, and most installations we complete take one to two days once permits clear. If you’re tired of PG&E time-of-use rates eating your evening budget, a battery lets you run your house off stored solar when the sun’s down and rates peak. Gus’s Solar has served Dixon homeowners with Solar Battery Storage & Backup work that’s engineered for one thing Sacramento installers miss: the I-80 wind corridor. Call (877) 550-6892 and Gus will walk you through the real math off your actual bill.
What makes Dixon different from Davis or Vacaville isn’t the sun. It’s the wind. And that changes how we size, mount, and permit your battery system.
Why Gus’s Solar Is Dixon’s Preferred Solar Battery Storage & Backup Company
We’re a locally owned, owner-operated shop that’s been around since 2011. Gus Petrakis puts his name on the truck, his address on the paperwork, and his cell number where you can actually reach it. When you call (877) 550-6892, a live person answers. Not a voicemail. Not a ticketing queue. Not a call center three states away.
Dixon homeowners call us because we already know what the City of Dixon building department is going to ask before we submit a single line of paperwork. That matters here more than most places. The wind corridor that funnels Delta breezes east through Solano County means your rooftop array and your battery enclosure both get held to a higher standard than the same system would in Sacramento or Woodland. We front-load the Category C wind specs so your permit doesn’t bounce back with a rejection letter and a two-week delay.
Gus’s crew does every install. No subs. You’ll see the same faces on your roof in the morning that you saw at your kitchen table during the quote. And if something isn’t right, the 90-Day Done Right Promise means one call brings Gus back. In writing. Every single job.
Our Solar Battery Storage & Backup Services in Dixon
Tesla Powerwall Installation
A Tesla Powerwall 3 installed in Dixon typically runs $11,000-$14,500 after installation but before the federal tax credit. The Powerwall handles whole-home backup when paired with the right inverter setup, and it’s a clean fit for the 1990s-2000s tract homes that dominate Dixon’s residential streets. We size the battery against your actual evening usage, not a brochure average.
Enphase IQ Battery Installation
The Enphase IQ Battery 5P runs about $8,500-$11,000 installed in Dixon, and it’s our most common recommendation for homeowners who already have Enphase microinverters on the roof. It’s a modular system, so you can start with one unit and add a second later if your needs grow. For Dixon homes with existing solar, this is often the fastest path to backup power.
Whole-Home Backup Power
Whole-home backup in Dixon usually means one to three batteries depending on whether you want to keep the AC running during an outage. Most Dixon homes need at least two Powerwall units or three IQ Batteries to cover a summer afternoon with air conditioning. We’ll pull your PG&E usage data and show you exactly what each battery configuration would keep running. No guessing.
Battery Retrofit for Existing Solar
This is the work we do most in Dixon. You’ve had solar for years. NEM 2.0 was fine, but now you’re on NEM 3.0 and selling power back for pennies while buying it back at peak rates. A battery retrofit changes that math. For a typical Dixon system, the retrofit including inverter compatibility work runs $10,000-$14,000. The payback comes from shifting your stored power into the evening hours when PG&E rates are highest.
We also handle Time-of-Use & NEM 3.0 Optimization and Battery Replacement & Expansion for Dixon homeowners who already have storage and need more capacity or a refresh on an older unit.

Trusted Brands We Service in Dixon
We install and service Tesla Powerwall and Enphase systems most often in Dixon, but we also work with FranklinWH and Panasonic battery lines. If you already have a system from another installer and it’s underperforming or throwing errors, we can service it. We carry common replacement parts and have direct distribution relationships with the manufacturers, which means faster turnaround than shops that order each part piecemeal. If you’re not sure what brand your current setup is, call (877) 550-6892 and we’ll help you identify it over the phone.
Common Solar Battery Storage & Backup Problems We See in Dixon Homes
- Wind-load permit rejections. A racking spec that passed in Sacramento gets flagged in Dixon because Solano County enforces exposure Category C. The fix is straightforward if you know it’s coming. Installers who don’t work this corridor regularly lose two to four weeks to revision rounds. We submit the right calculations the first time.
- Rapid shutdown violations on retrofits. Adding a battery to an older system with a string inverter often triggers rapid shutdown requirements at inspection. If the inverter doesn’t comply, the inspector stops the job. We check this before we ever schedule the install, and if a swap is needed we build it into the quote up front. No surprise line items mid-project.
- Tile-hook leaks on concrete tile roofs. Dixon’s 1990s-era tract homes largely have concrete tile. If a tile hook isn’t sealed to Solano County’s wind-driven rain standard, the first strong Delta gust event drives water under the tile and into your battery electrical room. Gus’s crew flashes every penetration properly, and we stand behind it.
- Undersized batteries for whole-home expectations. A homeowner installs one battery expecting it to run the AC, the fridge, and the well pump during a summer outage. It doesn’t. We see this often when someone bought from a national outfit that quoted the smallest system that would close the sale. We size for what you actually use, in August, during peak wind season when outages are most likely.
Pricing for Solar Battery Storage & Backup in Dixon, CA
Here’s what you’re looking at in Dixon, based on systems we’ve installed here through 2025:
- Single Enphase IQ Battery add-on: $8,500-$11,000

FAQs - Solar Battery Storage & Backup in Dixon
No, the wind corridor doesn’t change your battery sizing in kilowatt-hours. What it changes is the engineering and mounting specifications for everything attached to your roof and the exterior wall where the battery hangs. Your battery capacity is determined by your evening usage, not the wind. However, a Dixon home that loses power during a Delta gust event is often without power for longer because repair crews have to wait out the wind. We generally recommend one battery unit more than a comparable Sacramento home would need if the homeowner wants true whole-home coverage during extended outages. Call (877) 550-6892 and we’ll look at your actual usage numbers together.
Because the City of Dixon and Solano County enforce wind exposure Category C calculations for rooftop arrays, and most installers working out of Sacramento submit specs based on the calmer suburban wind maps they’re used to. Dixon’s afternoon Delta winds routinely exceed 25 mph, and the permit office knows it. If your installer flagged you for wind load, they didn’t spec the job for Dixon conditions. We front-load Category C racking calculations into every permit submittal we make in Dixon, because we’ve learned that lesson. Bring us the rejected permit and we’ll tell you what needs fixing.
Usually yes, but not always on the first visit. Dixon’s older downtown core has steeper roofs with wood sheathing that dates back decades, and some of them need structural assessment before we’ll mount racking or a battery. If the sheathing is solid, we can proceed. If it’s not, we’ll tell you exactly what needs reinforcing and what it will cost before anything goes on the roof. We won’t install a battery system on a roof that isn’t structurally sound enough to hold it through a wind event. That’s not a warranty issue, it’s a safety issue.
NEM 3.0 cut the export credit rate for excess solar by about 75%, which means the old playbook of selling daytime power back to PG&E at a premium is gone. In Dixon, where we get roughly 5.5 to 5.8 peak sun hours daily, a solar system still produces plenty of power. But without a battery, you’re giving that power away cheap at 2 pm and buying it back at peak rates at 7 pm. Adding a battery shifts your stored power into the evening and typically moves the payback period on the battery itself from around 12 years under NEM 2.0 down to 7 to 9 years under NEM 3.0, depending on your usage patterns and the current PG&E rate schedule. Call us and we’ll model this off your actual bill.
Yes, and this is where a lot of retrofit projects stall. When you add a battery to a system with an older string inverter, the local AHJ in Solano County will check rapid shutdown compliance at inspection. If your existing inverter doesn’t meet the current code, the inspector will stop the job. The fix is usually an inverter replacement or the addition of microinverters. We check this before we quote your retrofit so the inspection passes the first time. If you already have a quote from another installer that doesn’t mention rapid shutdown, get a second opinion. We’ll review it for free.
