Why Gus’s Solar Is Agoura Hills’s Preferred Solar Battery Storage & Backup Company
You won’t find a door-knocker from Gus’s Solar working the cul-de-sacs off Kanan Road. That’s not how we built our name in Agoura Hills. Gus Petrakis puts his own name on the truck, publishes his license number, and answers the phone himself. When a Fountainwood homeowner calls about a nuisance main-breaker trip at 9 p.m., a live person picks up. Not a voicemail tree. Not a call center in another state.
Agoura Hills customers have told us the same thing for years: they were quoted one number on the phone by a national outfit, then got a different number at the door. We don’t do that. The price we quote is the price you pay. And if it’s not done right, the 90-Day Done Right Promise means Gus comes back and makes it right. In writing, on every job.
We send our own background-checked, uniformed crew to every Agoura Hills job. Nobody gets handed off to a subcontractor who shows up in an unmarked van. You’ll recognize the people on your property, and Gus will be the one reviewing your system monitoring after the install. That’s the L.O.C.A.L. code we work by: Local roots, On time, Community first, Accountable, Loyal.
Our Solar Battery Storage & Backup Services in Agoura Hills
Every home in Agoura Hills is different. A 1970s tract house in Fountainwood has different panel constraints than a custom hillside rebuild off Liberty Canyon Road. We size your battery to your actual usage, not a brochure average. Here’s what we handle most in Agoura Hills:
Tesla Powerwall Installation
We install and configure Tesla Powerwall 3 and Powerwall 2 systems throughout Agoura Hills, including the 91301 and 91376 ZIP codes. If your home still has an original 100A panel, we’ll tell you upfront, before you spend a dime, whether you need a main panel upgrade to pass city inspection. Most Agoura Hills tract homes built in the 1970s and 1980s do. A typical Powerwall install in Agoura Hills runs $11,000 to $16,000, depending on whether a panel upgrade is needed.

Enphase IQ Battery Installation
The Enphase IQ Battery 5P is a quiet, modular option that pairs cleanly with existing solar arrays. We’ve installed these on rebuilt Agoura Hills homes where the homeowner already had Enphase microinverters on the roof. Because the battery talks natively to the same monitoring platform, the whole system reads on one app. Agoura Hills installs typically run $9,500 to $13,500 for a single 5P unit with installation.

Whole-Home Backup Power
Agoura Hills sits in a high-fire-risk zone, and SCE public safety power shutoffs are a real thing here. A whole-home backup system sized to your panel can keep your A/C compressor, well pump, and refrigeration running through a multi-day outage. We spec the system based on your actual load profile, pulling real consumption data from your SCE bill. If you want the A/C covered during a PSPS event in Old Agoura, we’ll size for it honestly and tell you what it costs.

Battery Retrofit for Existing Solar
This is the work we do most in Agoura Hills, and it’s where the post-Woolsey rebuild boom gives you an advantage most other cities don’t have. More on that below, but here’s the short version: if your rebuilt home has a 200 to 225A panel and pre-run conduit stubs, your retrofit often skips the separate electrical permit pull and a full day of labor. That can save $800 to $1,500 off the bill compared to what a neighboring Thousand Oaks installer would have to charge for the same job. Call (877) 550-6892 and we’ll check your panel on the first site visit.

Trusted Brands We Service in Agoura Hills
We work with the equipment homeowners in Agoura Hills actually ask for: Tesla, Enphase, SolarEdge, FranklinWH, and SunPower. That means we’re factory-trained on the systems already sitting on roofs in Fountainwood, Old Agoura, and the hillside custom builds along Mulholland Highway. When something throws an error code during a Santa Ana wind event, we don’t have to open a support ticket and wait two weeks. We stock common parts and can usually diagnose and fix the issue in one visit. If you have an existing Qcells or REC array from a different installer, we service those too.
Common Solar Battery Storage & Backup Problems We See in Agoura Hills Homes
- Main-breaker trips on rebuilt homes with EV chargers and pool heat pumps. Post-Woolsey rebuilds in Agoura Hills often have 200A panels, but a Tesla on a Level 2 charger plus a pool heat pump plus a battery backfeeding can push evening loads past the bus rating. We see nuisance trips that no one can explain until we map the actual load profile.
- Failed inspections on 100A panels in Fountainwood tract homes. The original 1970s homes off Thousand Oaks Boulevard were never built for solar plus storage. A Powerwall install on a 100A panel can fail city inspection on load-side tap sizing. We tell you this before you spend money, not after the inspector red-tags it.
- ‘Grid Quality’ errors during Santa Ana wind events. The Conejo Grade and Malibu Canyon corridors funnel high wind through Agoura Hills, and those gusts rattle conduit connections and junction boxes. A battery system wired into a loose connection will throw arc-fault or ground-fault codes. Our crew torques everything to the high end of manufacturer spec for exactly this reason.
- Battery systems installed by national outfits with no local follow-through. We get calls from Agoura Hills homeowners whose installer from three states away won’t return their calls after the system faults out. If a salesman needs an answer tonight, the answer is no. Gus’s Solar has a published address and a phone answered by a live person, and we service what we install.
What Agoura Hills’s Housing Stock Means for Your Battery Install
Agoura Hills is predominantly 1970s to 1990s suburban tract homes on flatter parcels near the 101 corridor, in neighborhoods like Fountainwood and the original Old Agoura subdivisions. Those homes frequently still have their original 100 to 150A electrical panels. That matters for battery storage, because a Tesla Powerwall or Enphase IQ Battery pulls through your main service panel, and an undersized panel can fail permit inspection on load-side tap sizing. We quote for the panel work honestly and up front when it’s needed.
Then there’s the other half of Agoura Hills: custom hillside homes built into the Santa Monica Mountains foothills. Many of these were destroyed in the Woolsey Fire of November 2018, which took over 1,600 structures in Agoura Hills alone. The homes rebuilt between 2019 and 2023 went up under California’s Title 24 mandate, which requires solar on new residential construction. That means a significant share of Agoura Hills’s current housing stock either already carries a mandated solar system that needs battery storage added, or was rebuilt with solar-ready conduit stubs already run to the roofline. Our Solar Battery Storage & Backup team knows to look for those stubs on the first site visit, because they can eliminate a full day of labor and a separate electrical permit pull. That’s real money saved.
Our crew recently upgraded a rebuilt custom hillside home off Liberty Canyon Road in the 91301 ZIP that had a 200A panel and solar-ready conduit stubs from its 2021 Woolsey rebuild. We tied an Enphase IQ Battery 5P into the existing microinverter array without a separate electrical permit, then programmed the system to arbitrage SCE’s time-of-use rates. The homeowner will likely see their true-up statement drop to near zero this year. That’s the kind of result that only comes from knowing Agoura Hills’s specific building stock, not from a zip-code-agnostic national quote.
How Agoura Hills’s Climate Affects Battery Performance and Payback
Agoura Hills sits in a sheltered inland valley between the Santa Monica Mountains and the Simi Hills. That geography gives the area roughly 5.5 to 5.8 peak sun hours daily, meaningfully better than coastal Malibu just ten miles south. For solar battery storage, that means more usable solar generation to charge your battery, which improves your time-of-use arbitrage math and shortens your payback period against SCE’s NEM 3.0 export rates. The battery fills earlier in the day and carries your evening loads longer.
But the same geography has a sharp edge. The Conejo Grade and Malibu Canyon corridors funnel intense Santa Ana wind events directly through Agoura Hills. Those winds don’t just threaten racking hardware, they shake conduit connections and junction boxes loose over time. A battery system wired into a rattled junction box will throw arc-fault or ground-fault errors that look like equipment failures but are really installation issues. We torque fasteners to the high end of manufacturer tolerances and we check conduit runs during every maintenance visit. If you’re in Agoura Hills and your battery keeps throwing errors after a wind event, call us before you reset it for the fifth time.

FAQs - Solar Battery Storage & Backup in Agoura Hills
Yes, in most cases you can. A 225A panel with solar-ready conduit stubs already run to the roofline is exactly what a battery retrofit wants to see. The conduit stubs mean we can pull wiring without opening walls or running new exterior conduit, and the 225A bus rating usually satisfies load-side tap sizing for a single Powerwall. That’s one of the quiet advantages of owning a post-Woolsey rebuild in Agoura Hills. Call (877) 550-6892 and we’ll confirm it on the first site visit.
Under SCE’s NEM 3.0 billing structure, solar exports to the grid are credited at a much lower rate than the retail price you pay for imported power. That crushes the economics of solar-only systems, but it actually strengthens the case for a battery. By storing your solar generation and discharging it during SCE’s 4 to 9 p.m. peak window, you avoid buying power at the most expensive time of day. A properly configured battery in Agoura Hills can turn a 12-year solar-only payback into a 7 to 9-year solar plus storage payback. We quote the year-25 output, not the day-one brochure number.
Grid Quality errors on Enphase batteries during high-wind events in Agoura Hills usually trace back to loose conduit connections or junction boxes rattled by the gusts funneling through the Conejo Grade corridor. The microinverters momentarily lose sync with the grid, and the battery logs the fault even if power never actually dropped. It’s not an Enphase defect, it’s an installation sensitivity. We torque all fasteners to the high end of manufacturer spec and check every junction box during maintenance visits. If you’re seeing repeated errors after a wind event, call us. We’ll come out and find the loose connection.
Yes. We retrofit batteries onto existing solar arrays all the time in Agoura Hills, including systems installed by national outfits during the post-Woolsey rebuild rush. The key is confirming your existing inverter is Powerwall-compatible and your panel has the headroom for the additional breaker. If the original installer is gone or won’t return your calls, we can take over the entire system monitoring and service. Gus’s name goes on the work, not someone else’s subcontracted crew.
It can, but only if we size for it. A single Powerwall 3 carries a 11.5 kW continuous output rating, which covers a standard central A/C compressor plus refrigerator and lighting, but it won’t cover a pool heat pump and a 48-amp EV charger at the same time. For whole-home backup in Old Agoura or anywhere in the 91301 ZIP, we map your actual evening load profile from your SCE bill and size the system honestly. Some homes need two batteries. Some need one. We’ll tell you which one yours is. Call (877) 550-6892 for a free estimate, and take two weeks to think about it. The price won’t change.
