Fast, Reliable Solar Battery Storage & Backup Across Hanford
A typical home battery installation in Hanford runs $12,000-$18,500 before incentives, and most jobs are completed in one day. The bigger question here isn’t price. It’s whether your battery is sized for a Hanford winter, not a San Diego winter. Tule fog changes the math in a way most California solar shops don’t account for, and we’ll walk you through exactly what that means for your home before you spend a dollar. Call (877) 550-6892 and we’ll come out to your place, look at your panel and your actual usage, and give you a straight answer.
We’re Gus’s Solar. We’ve been doing Solar Battery Storage & Backup work in the Central Valley since 2011, and we know what a week of fog does to a system out here. If you’re in the 93230 or 93232 ZIP, we’re in your neighborhood regularly and can usually be at your door within a day or two of your call.
Why Gus’s Solar Is Hanford’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011 and still runs it himself. You call the office, you talk to a real person. You’ve got a problem at 10 p.m. during a fog-season outage, a real person answers. Not a call center, not a phone tree, not a ticket queue. We built our reputation across Hanford by answering when people call and showing up when we say we will.
Our Google reviews from Hanford homeowners consistently point to the same three things: we show up on time, we charge what we quoted, and when something isn’t right, Gus comes back and makes it right. That last part is in writing. Every solar job carries our 90-Day Done Right Promise, and that promise applies to battery work the same as it applies to a full roof install. One call brings Gus back. No argument, no runaround.
Hanford isn’t a side market for us. We’ve done battery retrofits on ranch homes off 12th Avenue, new builds near Hidden Valley Park, and acreage properties out by the dairy corridor where the dust loads are brutal. That local experience means we don’t have to guess how fog and soiling will affect your recharge cycles. We already know.
Our Solar Battery Storage & Backup Services in Hanford
Battery Retrofit for Existing Solar
Most Hanford homes that call us already have solar. The system went in between 2015 and 2020, back when net metering let you push daytime power to the grid and pull it back at night. Then NEM 3.0 landed and gutted that arrangement. Adding a battery to an existing array is the most common job we do in the 93230 ZIP, and it’s often more involved than a fresh install. Older string inverters, undersized main panels, and rapid-shutdown compliance all have to be sorted before the battery goes in. We handle that entire retrofit without subbing anything out.

Whole-Home Backup Power
On a standard Hanford ranch-style home, a partial backup that covers your fridge, a few lights, and one bedroom is fine. On an acreage property with a well, it’s not enough. A well pump pulls hard on startup, and a septic lift pump is non-negotiable during an outage unless you want sewage backing up. Our whole-home backup installs are built heavy for those rural Hanford properties: well pump, septic, garage door opener, and HVAC all stay live when the grid drops. Partial backup saves money up front. Whole-home backup is what actually works out here.

Time-of-Use & NEM 3.0 Optimization
Hanford sits in PG&E’s NEM 3.0 territory, which means your exported solar credits are worth a fraction of what they were under NEM 2.0. The practical fix is to store midday production and use it during the 4-9 p.m. peak window when PG&E charges the most. We program your battery and inverter around your actual bill, not a generic template. If your export rates are higher in summer and your winter usage spikes when the fog sits for a week, we model that. Bring us a bill, we’ll bring you the math.

Tesla Powerwall Installation
We’re certified to install and service Tesla Powerwall, and a good portion of the battery work we do in Hanford is Powerwall retrofits on existing homes. The Powerwall 3’s integrated inverter simplifies things on older homes where the original string inverter is nearing end of life. We quote the year-25 output, not the day-one brochure number, and that’s especially relevant in Hanford where winter fog makes day-one numbers look like a lie by February.

Trusted Brands We Service in Hanford
We stock and service Enphase and Tesla battery systems and regularly pair them with Qcells, Panasonic, and REC modules on Hanford projects. If your existing array came with Enphase microinverters, we can often integrate a battery without replacing your entire inverter stack. We keep common components in stock locally, which means most Hanford service calls get resolved in one trip instead of waiting on a part to ship from a warehouse in Atlanta. That matters during an outage.
Common Solar Battery Storage & Backup Problems We See in Hanford Homes
- Batteries sized off a coastal production model. A battery bank that covers a Fresno home for a week of overcast drains in three days of Hanford tule fog. If your installer used a generic California solar model, your backup runs dry exactly when you need it most. Our sizing starts with Kings County irradiance data and your actual winter usage.
- Dust soiling never factored into recharge math. By August, the dust from Hanford’s dairies and row-crop operations cuts panel output 10-15%. That means a battery that looked sized for a full overnight top-off ends up cycling deeper than designed. Deeper cycling ages batteries faster. We bake cleaning into our service agreements for Hanford customers and adjust recharge assumptions accordingly.
- Partial backup that drops the septic lift pump or well pump. We’ve responded to acreage homes where the previous installer put the well on a non-backed-up circuit. First outage, no water, no flushing. A Hanford home without city sewer and city water can’t tolerate that. Our whole-home designs specifically include those loads.
- Old string inverters fighting rapid shutdown. Homes built in the 1970s and 1980s off 12th Avenue and around the 93230 ZIP often have original or aging solar equipment that predates current rapid-shutdown requirements. Retrofitting a battery onto that system sometimes means pairing it with microinverters instead of forcing the old central inverter to do a job it wasn’t designed for.
The Tule Fog Problem: What Nobody Tells You About Batteries in Hanford
Here’s the part of this page you won’t read on any other solar company’s website, because most of them write the same generic battery pitch for every city in California. Hanford sits on the Kings County valley floor, and between November and February, tule fog can sit on this town for days or weeks without breaking. Your panels make almost nothing during those stretches. Not 50% less. Something closer to 80-90% less, for days at a time.
That flips the entire value proposition of a battery. In summer, a battery saves you money by arbitraging PG&E’s time-of-use rates: charge cheap, discharge expensive. In winter, in Hanford, a battery is the only thing keeping your lights, your fridge, your well pump, and your garage door opener running through a week-long zero-production stretch. If your installer sized the battery off a generic California model, you’ll find out the hard way on day three of fog.
On a 1970s ranch home off 12th Avenue in the 93230 ZIP, our crew retrofitted an existing roof system with two Tesla Powerwalls. The owner’s old string inverter was choking on rapid shutdown, so we paired the batteries with Enphase microinverters on the dusty south-facing array. Now his whole-home backup keeps the well pump, septic lift, and garage door opener live when tule fog kills production for five straight days, and the batteries recharge during the few clear afternoon hours we get in January. That’s what a Hanford-specific battery design looks like.
Pricing for Solar Battery Storage & Backup in Hanford, CA
Here’s what you’re looking at in the Hanford market as of 2026. A single Tesla Powerwall 3 installed without solar runs roughly $12,500-$15,000. Adding a second battery usually brings the total to $21,000-$26,000, but the per-battery cost drops. A full Enphase IQ Battery 5P stack for whole-home backup on a Hanford acreage property typically lands between $16,000 and $24,000 depending on how many loads you’re backing up. A retrofit onto an existing solar system adds $1,500-$4,000 in electrical panel and inverter work, more if your main panel needs an upgrade.
What drives cost in Hanford specifically: the size of your well pump, whether you’re on a septic system, how much dust remediation your array needs, and whether your existing inverter can talk to the battery or needs to be replaced. We quote the price up front, off your actual usage and your actual wiring, not a brochure estimate. The number you see is the number you pay. No signature wanted tonight. Take two weeks. Think about it. The price will be the same. Call (877) 550-6892 and we’ll come out, do the walkthrough, and give you a real number.

FAQs - Solar Battery Storage & Backup in Hanford
A typical Hanford home needs 20-30 kWh of usable storage to cover essential loads through a five-to-seven-day fog stretch, assuming one clear afternoon at some point for a partial recharge. That usually means two Tesla Powerwalls or a comparable Enphase stack. A single 13.5 kWh Powerwall covers about three days of essentials in deep fog. Call (877) 550-6892 and bring us a winter bill. We’ll size it off your actual numbers, not a guess.
Yes, and it’s because Hanford’s winter fog creates deeper and longer grid-dependency windows than Fresno or Visalia see. Under NEM 3.0, your exported solar credits are worth little, so storing midday summer production and discharging during PG&E’s 4-9 p.m. peak pays off faster the more expensive your evening usage is. Hanford households with well pumps and pool pumps see payback periods roughly 10-20% shorter than homes without those heavy evening loads. We’ll run your actual bill through the model and show you the year-by-year arithmetic.
Sometimes. If your existing system uses Enphase microinverters, you can usually add an Enphase battery without pulling the whole array apart. If you have an older string inverter from the 2010s, you’ll likely need to pair the battery with new inverter hardware, which adds cost but often improves your array’s output in the bargain. We’ll tell you which path applies to your system during the free walkthrough, and we won’t sell you a new inverter unless yours genuinely can’t do the job.
Dust from Kings County dairies, cotton fields, and row crops settles on your panels and cuts output by 10-15% by late summer if nothing washes it off. Since Hanford gets almost no rain between June and October, that soiling doesn’t rinse away naturally. For a battery system, that means your array produces less power to refill the battery, so the battery cycles deeper and ages faster. We bake panel cleaning into our Hanford service agreements specifically because this problem is worse here than in most of California. A clean array in July is the difference between a battery that lasts 10 years and one that limps to 7.
Only if those circuits are on the backed-up panel. A standard partial backup often excludes the well pump and garage door opener, and on a Hanford acreage home that means no water and no way to get your car out during an outage. Our whole-home backup designs explicitly include the well pump, septic lift pump, and garage door opener because we know those are the loads a Hanford home can’t live without. Call (877) 550-6892 and we’ll verify exactly what’s on your backed-up panel before we quote anything.
