It’s what keeps your lights on when Southern California Edison cuts power during a Santa Ana wind event, which happens several times a year in this canyon. Gus’s Solar installs Solar Battery Storage & Backup systems sized for the way Topanga homes actually use power: well pumps, refrigerators, medical devices, and the long stretches when the grid simply isn’t there. We know the canyon roads, the protected oaks, the old roof framing, and the permitting quirks of LA County. Call us at (877) 550-6892 and a live person answers, day or night.
Why Gus’s Solar Is Topanga’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011 and put his own name on the truck. Homeowners in Topanga call us because they’ve dealt with the door-knockers who quote one number on the phone and a different number at the door. We quote the year-25 output, not the day-one brochure number. The estimate you get is built off your actual utility bill. Bring me a bill, I’ll bring you the math. That’s how we’ve done it for over 29 years in local communities, and we don’t plan on changing.
Every job comes with the 90-Day Done Right Promise in writing. If something isn’t right, Gus makes it right. One call brings him back. The crew that installs your battery is Gus’s own crew: background-checked, uniformed, and the same faces you’ll see at the hardware store. No subs. No strangers on your roof. And when you call our number, a live person picks up 24/7. Not a voicemail, not a ticketing portal.
Topanga homeowners tell us the same thing: they want a name they can verify and a company that won’t disappear the morning after the system goes live. Gus publishes his address and license number. He’s accountable. That’s the L.O.C.A.L. code we run on: Local roots, On time, Community first, Accountable, Loyal.
Our Solar Battery Storage & Backup Services in Topanga
Most Topanga homes need a specific kind of battery work, because most Topanga solar was installed years ago without storage. Our Topanga team handles retrofits, new installs, whole-home backup, and everything in between. Here’s what we do most often.
Tesla Powerwall Installation
A Tesla Powerwall installation in Topanga typically runs $13,500 to $18,500 including gateway hardware and wiring, before any local rebates. Two Powerwalls usually fall between $24,000 and $32,000. In a canyon home with a well pump and a full-sized refrigerator plus freezer, we typically recommend at least two units for whole-home coverage. One Powerwall will keep essentials running; two will keep life feeling normal during a two-day PSPS shutoff.
Enphase IQ Battery Installation
Enphase IQ batteries pair exceptionally well with the east/west roof orientations common in Topanga, where protected oaks shade the south face. The modular design means we can start with one unit and add capacity later, which matters for homeowners who want to spread the cost. Expect $12,000 to $20,000 for a typical Enphase install in the 90290 area, depending on capacity and whether we’re adding it to an existing Enphase microinverter system or converting from a legacy string inverter at the same time.
Whole-Home Backup Power
Whole-home backup means your entire panel keeps running when the grid drops: HVAC, well pump, septic pump if you have one, every circuit. In Topanga this is the spec most homeowners actually need, because PSPS events don’t just knock out lights. They knock out water pressure and refrigeration for days. Sizing a whole-home system starts with a load calculation off your real bill and a walk-through of your panel. A typical whole-home setup in Topanga runs $28,000 to $45,000 installed.
Battery Retrofit for Existing Solar
A battery retrofit for existing solar in Topanga usually lands between $15,000 and $26,000. That includes the battery, new inverter or microinverter conversion if your old system needs it, and the electrical work to make everything play nice with SCE’s interconnection requirements. If your system went in before 2020, it’s likely a string inverter with no rapid shutdown, and retrofitting means upgrading that too. We’ll tell you exactly what’s needed, and the price won’t change at the door.

Trusted Brands We Service in Topanga
We work with Panasonic, FranklinWH, and Canadian Solar equipment, along with Tesla and Enphase for battery systems. Because we’re locally based and we stock common parts for Topanga customers, we can often handle service calls and warranty work faster than an out-of-state company that has to ship components across the country. Your warranty stays valid because we’re factory-trained and approved on the brands we install. We don’t push one brand. We match the equipment to your roof, your panel, and the way the canyon treats your production.
Common Solar Battery Storage & Backup Problems We See in Topanga Homes
- PSPS shutoffs leave legacy grid-tied systems dead. Older solar setups without batteries shut down automatically when the grid drops, for lineworker safety. During a Santa Ana wind event, that means a house with $30,000 of solar panels sits dark unless there’s a battery attached. We retrofit these systems so the power you make is power you actually keep.
- Protected oaks shade the ideal south-facing roof. LA County’s Oak Tree Ordinance means you can’t trim or remove native oaks without permits, and in Topanga those trees are everywhere. We regularly design around a shaded south roof by moving modules east or west and using power optimizers or microinverters so production doesn’t collapse.
- Aging 1950s-1970s roof framing fails modern load calculations. Many Topanga cabins and hillside homes were built before current structural standards. Adding a battery and panels means the roof has to carry more weight, and we’ve seen plenty of rafters that need sistering or reinforcement before the county will approve interconnection.
- The marine layer cuts more production than irradiance maps suggest. Canyon-floor and north-facing lots in Topanga see morning fog off the Pacific. We size battery systems with real site-specific shading analysis, not a generic map, so your battery actually gets enough charge during the day to carry you through the night.
Pricing for Solar Battery Storage & Backup in Topanga, CA
Here’s what you can expect to pay in the 90290 area. A single-battery retrofit typically runs $15,000 to $20,000. A full solar-plus-battery install with a new array and one battery lands between $28,000 and $42,000. Two-battery whole-home systems run $35,000 to $55,000 depending on your roof and panel. Roof reinforcement, if needed, adds $2,000 to $8,000 depending on scope. Protected-oak relocations of your array don’t change battery cost, but they do change panel layout and can add microinverter or optimizer hardware at $150 to $250 per module. We don’t ask for a signature tonight. Take two weeks. Think about it. The price will be the same. Call (877) 550-6892 for a free estimate built off your actual bill.

FAQs - Solar Battery Storage & Backup in Topanga
Because Topanga sits entirely within a Very High Fire Hazard Severity Zone, and Southern California Edison cuts power across the canyon during Santa Ana wind events as a fire-prevention measure. Woodland Hills doesn’t see the same frequency or duration of Public Safety Power Shutoffs. Without a battery, your solar system shuts off when the grid drops. With a battery, you stay powered through the outage. Call (877) 550-6892 and we’ll walk you through what your exact address would need.
Yes, and it happens often in Topanga. LA County’s Oak Tree Ordinance prohibits trimming or encroaching on native oaks without county permits, which are rarely granted just to improve solar access. If a protected oak shades your south roof, your array goes east or west. That’s fine, as long as we design for it with microinverters or power optimizers. We’ve retrofitted systems where the original installer ignored the shading and production collapsed.
Santa Ana events don’t directly harm your battery, but they trigger the PSPS shutoffs that make the battery essential. The canyon also funnels and amplifies wind, which can expose loose roof penetrations and wiring. We flash every penetration properly and inspect existing arrays before adding storage. A well-installed battery system rides through wind events without issue.
Possibly. Many Topanga homes from the 1950s through 1970s have roof framing that predates modern structural load requirements. Adding panels and a battery adds weight. County inspectors will flag undersized rafters. We do a structural evaluation as part of every quote and tell you upfront if reinforcement is needed, so there’s no mid-project surprise.
It can. Canyon-floor and north-facing properties in Topanga see more morning fog from the Pacific than the solar maps assume. If your array gets fewer peak sun hours, your battery charges slower and you may need either more modules or a larger battery to hit the same overnight coverage. We use site-specific shading analysis, not regional averages. Come talk to us and we’ll show you the real numbers.
