Fast, Reliable EV Charger Installation Across Cupertino
Most Cupertino homes weren’t wired for the EV future. The ranch houses that line De Anza Boulevard and the streets off Stevens Creek Boulevard were built in the 1960s and early 1970s, back when a 100-amp panel was plenty. Today, adding a Level 2 charger to one of those garages usually means a panel upgrade first. Our EV Charger Installation team does both jobs in one visit, and we know Cupertino’s permit process cold. Call (877) 550-6892 for a no-pressure estimate, and take two weeks to think about it. The price will be the same.
We’re a local, owner-operated shop. Gus Petrakis answers his own phone, publishes his license number, and sends his own background-checked crew to every job in 95014 and 95015. No subs, no call center, no sales script. Just a straight answer and a fair number.
Why Gus’s Solar Is Cupertino’s Preferred EV Charger Installation Company
Cupertino homeowners don’t hire the first name that pops up in a Google ad. They read spec sheets, compare charger amperage, and ask about load calculations before you’ve finished saying hello. We like that. Gus founded this company in 2011, and his approach matches how Cupertino thinks: bring your PG&E bill, we’ll bring you the math.
Our reputation in Cupertino comes from doing the work right the first time. The 90-Day Done Right Promise is in writing on every job: if something isn’t right, Gus makes it right, and one call brings him back. No escalation chain, no support ticket. A live person answers our phone 24/7, not a voicemail box.
Response time matters when your charger trips and you need the car charged for the morning commute up 280. We schedule Cupertino calls quickly, and we quote a firm arrival window, not “sometime between 8 and 5.”
We also know Cupertino’s electrical inspectors and what the Building Division looks for on a charger permit. That’s not a small thing. It means fewer red tags, fewer follow-up visits, and a faster path from permit to plugging in.
Our EV Charger Installation Services in Cupertino
Level 2 Charger Installation
Level 2 is what most Cupertino homeowners want: 240-volt service that fills a typical EV battery overnight instead of the two days a standard wall outlet takes. In a Cupertino garage, that usually means a dedicated 40-amp or 50-amp circuit, a hardwired charger or NEMA 14-50 outlet, and a permit. We handle all of it. A typical Level 2 charger installation in Cupertino runs $800 to $1,400 when the panel has spare capacity and $2,500 to $4,500 when it doesn’t.

Tesla Wall Connector Installation
Given how many Teslas roll through Cupertino, this is one of our most common requests. We install Tesla Wall Connectors in garages off Monte Vista and along Foothill Expressway, and we wire them to make full use of your panel’s available amperage. The Gen 3 Wall Connector is straightforward to mount, but the electrical work behind it is the same serious business: dedicated circuit, proper breaker size, torque-checked connections, and a load calculation. We’re happy to install your Tesla Wall Connector or supply one. A typical Tesla Wall Connector installation in Cupertino runs $900 to $1,600 depending on the distance from the panel to the mounting location.

Panel Upgrade for EV Charging
This is where Cupertino’s housing stock catches people off guard. The original 100-amp panels in those mid-century ranch homes weren’t sized for a 48-amp car charger, much less a charger plus solar plus a battery. Upgrading to 200-amp service is often the first step, not a maybe. A panel upgrade in Cupertino typically adds $3,500 to $6,000 to the job, depending on whether the meter main needs to be reconfigured and whether your existing branch wiring can be reused. We’ll tell you straight if your panel can handle the load, and we won’t sell you a 200-amp panel if a 125-amp subpanel will do the job for less.

Garage & Driveway Charger Wiring
Most Cupertino chargers land in a garage, but we also wire driveway and carport chargers for homes without enclosed parking. Surface-mount conduit along an exterior wall, weather-rated enclosures, and proper burial for the run from panel to post: we’ve done all of it in Cupertino’s older neighborhoods and newer tracts alike. If you park in a driveway off Portal Plaza or near Rancho Rinconada, we can put a charger post exactly where you need it.

Trusted Brands We Service in Cupertino
We install and service chargers and the equipment that feeds them from the brands Cupertino homeowners actually ask for: Tesla, Enphase, SolarEdge, and FranklinWH. We keep common breakers, wire, and conduit on the truck, which means fewer mid-job supply runs to San Jose for a part. If you already own a charger from a different manufacturer, we’ll install that too. No requirement to buy our hardware.
Common EV Charger Installation Problems We See in Cupertino Homes
- 100-amp panels that can’t take the load. This is the single most common issue in Cupertino, especially in the ranch homes built off McClellan Road and around Garden Gate. A 48-amp charger pulls 60 amps at the breaker. Add an electric dryer, an AC condenser, and a pool pump, and you’re over capacity. We run the load calculation before quoting so there are no surprises.
- Garages with a single shared circuit. Many older Cupertino garages run lights, outlets, and the garage door opener on one 15-amp circuit. That won’t support a charger, and tapping into it is genuinely dangerous. The fix is a new dedicated home run, and we pull the permit for it.
- Aluminum branch wiring from the original build. We occasionally open a Cupertino panel and find aluminum wire feeding branch circuits. Aluminum expands and contracts with temperature, which can loosen connections over time. That’s a fire risk on a high-draw circuit, and we address it before connecting a charger.
- PG&E NEM 3.0 timing and the solar-plus-EV pile-up. Cupertino homeowners who add solar and a charger at the same time face two different approval paths: the city permit and the PG&E interconnection application. We batch those so the utility clock starts early, which can shave weeks off your final activation date.
Pricing for EV Charger Installation in Cupertino, CA
Here’s the straight math, not a brochure number. A basic Level 2 charger installation with a short run from a panel that has spare capacity: $800 to $1,400. A Tesla Wall Connector: similar, typically $900 to $1,600. Adding a panel upgrade because your Cupertino home still runs a 100-amp main: $3,500 to $6,000 on top. Long conduit runs, trenching for a driveway post, or a subpanel in a detached carport push toward the upper end. We quote off your actual utility bill and your actual panel, not a guess. Estimates are free, and no trip charge applies inside our own county. Call (877) 550-6892 and we’ll send a real person to look.

FAQs - EV Charger Installation in Cupertino
Most Cupertino jobs are scheduled within a week, and emergency charger failures get same-day attention when a live person answers the phone. Call (877) 550-6892 to lock in a window. We don’t do four-hour arrival windows unless there’s an actual emergency on the truck log.
Yes, we cover both Cupertino zip codes, from the neighborhoods off Stevens Creek Boulevard up to the foothills near Monte Vista. That includes the older ranch-home pockets and the newer townhouse developments alike. If you’re in Cupertino, we’ll be there.
We do. If your charger trips a breaker at 9 p.m. and you need the car charged for a 6 a.m. flight out of SJC, call (877) 550-6892. A live person answers, not a voicemail. For genuinely dangerous conditions like a burning smell or a warm breaker, shut the circuit off at the panel and call us right away.
Cupertino’s pricing runs a bit above Sunnyvale or Mountain View, mostly because the city’s permit fees are what they are and the older housing stock means more panel upgrades. That’s not a markup; it’s the actual cost of doing the work to code. We’ll show you the line items.
Yes. Every charger install in Cupertino is covered by the 90-Day Done Right Promise, plus the manufacturer’s warranty on the equipment itself. If something isn’t right, one call brings Gus back. That’s in writing on your invoice before you pay.
