Fast, Reliable EV Charger Installation Across Fairfax
EV charger installation in Fairfax, CA typically costs $800-$2,400 for a standard Level 2 setup, depending on your panel’s capacity and how far the charger sits from your electrical service. We serve all of Fairfax, including the hillside streets off Sir Francis Drake Boulevard and the neighborhoods around downtown. If your home still runs a 100-amp panel from the 1950s or 60s, that’s the thing that adds the most to your bill - and it’s also the thing most national installers won’t flag until after you’ve signed.
Gus Petrakis has been putting his own name on electrical and solar work across Marin County since 2011. When you call (877) 550-6892, you get a real person. Not a call center. Not a voicemail. We’ll talk through your EV, your driving habits, and your current panel before we ever send a crew to Fairfax.
Why Gus’s Solar Is Fairfax’s Preferred EV Charger Installation Company
Fairfax isn’t a generic suburb. The lots are steep, the trees are protected by a serious permit process, and half the homes still carry electrical infrastructure from the Eisenhower administration. That combination breaks a lot of standard charger installs. We know before we arrive that a 1952 hillside house off Scenic Road will probably need a panel upgrade, and that the conduit route matters because nobody wants a trench cut through redwood roots. That’s not something a national call center knows. It’s something you learn by doing the work here.
Our EV Charger Installation team handles everything in-house. Gus’s own crew shows up in uniform, background-checked, and they don’t hand the job off to a subcontractor. When something goes wrong later, the same people come back. That matters to Fairfax homeowners who’ve been burned by outfits that vanish after the paperwork clears. Our 90-Day Done Right Promise is in writing on every job: if it isn’t right, we make it right.
We answer calls around the clock, including weekends. Fairfax is small enough that we can usually be there the same afternoon or next morning. When your charger trips a breaker at 9 p.m. and you need your car for a morning commute down to Larkspur, you don’t want a ticketing portal. You want a person.
Our EV Charger Installation Services in Fairfax
Level 2 Charger Installation
A Level 2 charger adds roughly 25-35 miles of range per hour of charging, versus maybe 4 miles on a standard wall outlet. Most Fairfax homes we visit get a 40-amp or 48-amp circuit run from the main panel to a garage or driveway-mounted charger. On the older hillside homes near Deer Park, we often run surface-mounted conduit along the garage exterior rather than tearing into finished walls - less dust, less patching, same clean result.

Tesla Wall Connector Installation
The Tesla Wall Connector is a favorite in Fairfax for a simple reason: it pairs directly with a Tesla’s onboard software, including scheduled charging during off-peak hours. We install them in garages, carports, and on exterior walls where the driveway meets the house. One thing to know: on homes built before 1965 along Bolinas Road, the main panel is almost always undersized for the charger’s 48-amp draw, which means a service upgrade usually comes first.

Panel Upgrade for EV Charging
This is the service we talk about most with Fairfax homeowners. A 100-amp panel from the 1950s can’t safely power a Level 2 charger plus an electric dryer, oven, and heat pump. Fairfax’s building department won’t sign off on an interconnection with that kind of load on a legacy panel. We upgrade to 200 amps, re-label everything, and pull the permit properly. No shortcuts that fail inspection later. Cost in Fairfax runs $2,800-$4,500 depending on whether your meter box and grounding system also need work.

Garage & Driveway Charger Wiring
Fairfax has a real mix: detached garages, carports tucked under decks, and steep driveways where parking happens fifty feet from the house. Each of those demands a different wiring route. We’ve run conduit along retaining walls up in the hills near White Hill, and we’ve sleeved cable under sidewalks in the flats near downtown. Whatever the path, we keep it clean, code-compliant, and painted to match the structure where practical.

Trusted Brands We Service in Fairfax
We work with the equipment Fairfax homeowners actually choose: Tesla Wall Connectors, Enphase IQ chargers, SolarEdge EV charging inverters, and FranklinWH battery-integrated setups for solar-paired charging. We also regularly service Panasonic EV charging units alongside existing solar installations. Because Fairfax’s tree canopy and terrain don’t change, our trucks carry the fittings and breakers we reach for most - no “we’ll order that part and come back next week.” When you need a 50-amp GFCI breaker tomorrow morning, it’s already on the shelf in our Bay Area shop.
Common EV Charger Installation Problems We See in Fairfax Homes
- 100-amp panels on 1950s hillside homes. Fairfax has a high concentration of original panels that can’t pass a load calculation with a Level 2 charger. Upgrading to 200 amps is the norm here, not the exception.
- Tree root zones blocking underground conduit routes. Between the redwoods and coast live oaks on lots near Oak Manor Drive and Scenic Road, trenching through a mature root zone is often impossible or destructive. We route above ground where the tree matters more than a buried cable.
- Long driveway runs driving up material costs. Fairfax’s steep lots mean chargers often sit 75 feet or more from the panel. Copper isn’t cheap, and voltage drop matters. We size conductors correctly, which some low-ball quotes skip.
- Solar arrays that undershoot production because of canopy shade. We see homes where a string-inverter system was sold without accounting for the valley’s extended morning and afternoon shadow lines. The panels produce fine at noon, but the owner still imports expensive grid power at night. Pairing the charger with shade-tolerant Enphase microinverters changes that math.
Pricing for EV Charger Installation in Fairfax, CA
A straightforward Level 2 charger install in Fairfax, where the panel is already 200 amps and the charger sits within 25 feet of the main panel, runs $800-$1,400. A Tesla Wall Connector install with a longer conduit run typically lands between $1,200 and $2,400. If you need a panel upgrade to 200 amps, add $2,800-$4,500 on top of the charger work. Solar-paired charging - where the charger coordinates with an existing or new array - starts around $1,500 for the charger side, not counting any panel work. We give you one number before you ever sign anything. Bring us a recent PG&E bill and we’ll show you the exact payback math for charging on sunlight versus buying grid power at Marin’s peak rates. The price we quote is the price you pay. Take two weeks to think about it. The number won’t change.

FAQs - EV Charger Installation in Fairfax
Yes, at certain times of day. Fairfax sits in an inland valley where the surrounding ridgelines block direct sun for part of the morning and late afternoon, well beyond what a satellite shading model predicts. If your array feeds a charger through an Enphase microinverter system, each panel harvests independently, so partial shade on one section doesn’t kill the whole array’s output. That’s the setup we recommend for solar-paired EV charging on most Fairfax lots. Call (877) 550-6892 and we’ll read your actual production numbers before recommending anything.
In most Fairfax homes we visit, yes. A Level 2 charger draws 40-48 amps continuously, and a 100-amp panel from the 1940s through early 1970s simply doesn’t have the headroom once you account for the dryer, oven, and any heat pump or electric water heater. The Fairfax building department will not approve a charger circuit on an undersized panel. Plan on a panel upgrade if your service is still 100 amps.
Yes, and around here that’s the whole point. We never suggest trimming or removing a tree to improve solar access in Fairfax - that’s a fast way to lose the deal and insult the homeowner, given the town’s strict tree-removal permit process and residents’ attachment to mature redwoods and oaks. Instead, we add the charger to your existing panel, and if production is short of what you need, we adjust the charger’s schedule to pull from the grid only during off-peak hours when PG&E rates are lowest in Marin.
It means the people we serve here care about where their electrons come from in a way many towns don’t. Fairfax was the first U.S. city to ban plastic bags back in 2007, and that environmental conscience shows up in every consultation we do. Most Fairfax homeowners want a charger that can be fed primarily by solar, not one that simply adds grid load. We design installations around that: Enphase microinverters for shaded arrays, chargers that schedule for full-sun hours, and panel upgrades sized for future electrification, not just today’s load.
On a shaded Fairfax lot, a solar-paired EV charger typically pays back in 6-9 years when you account for avoided gasoline purchases and PG&E’s peak electric rates in Marin, assuming your array already exists or is being installed concurrently. If you’re paying to add solar at the same time on a heavily shaded site, the payback stretches toward the 10-12 year mark. We’ll show you the real numbers from your actual bill before you commit - no brochure math.
