Fast, Reliable EV Charger Installation Across Claremont
Most Claremont homeowners call us after the charger purchase, not before it. They’ve already bought the unit or they’re thinking about a Tesla Wall Connector, and then they realize the 100-amp panel in their 1950s ranch home won’t handle a 48-amp draw on a July afternoon when the AC is running full blast. That’s where we come in. Gus’s Solar has been doing EV Charger Installation across Claremont long enough to know the tree ordinance, the panel age, the heat derating issues, and which garage walls actually make sense for mounting. We coordinate from our LA-area office and send our own crew to Claremont, usually within a day or two. Call (877) 550-6892 and a live person picks up. No call center, no voicemail after hours.
Why Gus’s Solar Is Claremont’s Preferred EV Charger Installation Company
Gus Petrakis puts his name on the truck and his number on the estimate. He founded this company in 2011, and he still answers the phone. Claremont homeowners tell us the same thing: they’ve dealt with out-of-state outfits that quoted one number on the phone and a different one at the door. That’s not how we work. We quote off your actual utility bill and your actual panel, not a brochure. Bring us a bill and we’ll bring you the math.
Our crew knows Claremont. They know the Craftsman bungalows near the Village with original 100-amp panels and the mid-century ranch homes off Indian Hill Boulevard. They know that the city’s arborist review matters when conduit runs near protected trees. They know that a south-facing garage wall in Claremont bakes at 100°F-plus in summer and that heat derating on a charger is a real problem, not a theoretical one. That local knowledge means fewer callbacks and cleaner installs.
We back every job with the 90-Day Done Right Promise. If it’s not done right, Gus makes it right, in writing. And we never ask for a signature tonight. Take two weeks. Think about it. The price will be the same.
Our EV Charger Installation Services in Claremont
Level 2 Charger Installation
Level 2 charging is the sweet spot for most Claremont homeowners. A 240-volt circuit delivers roughly 25 to 30 miles of range per hour, which means a full overnight charge instead of a three-day trickle from a wall outlet. Most of the Level 2 installs we do in Claremont involve running a new dedicated circuit from the panel to the garage or driveway, and that’s where the older housing stock gets tricky. We’ll tell you honestly if your panel can handle the load before we quote anything.

Tesla Wall Connector Installation
We install Tesla Wall Connectors all over Claremont, from the condos near the Colleges to the larger custom homes on the north end near the foothills. The Wall Connector can pull up to 48 amps, which means a panel upgrade is often part of the job in older Claremont homes. We run the circuit, mount the unit, and configure it for your home’s actual available amperage so it charges as fast as your panel safely allows. If you’ve got a Tesla on order, call us before it arrives.

Panel Upgrade for EV Charging
This is the most common call we get from Claremont, and it’s usually not the call the homeowner expected to make. A 100-amp panel in a 1950s ranch home or pre-WWII Craftsman near the Village simply can’t support a 48-amp charger plus a central AC system plus everything else a modern house draws. In Claremont, a panel upgrade for EV charging typically runs $2,800 to $4,500 depending on the panel location, meter configuration, and whether the city requires additional grounding or service entrance work. We’ll open the panel, look at the actual loads, and tell you what you need. No upsell, just the math.

Garage & Driveway Charger Wiring
Claremont garages come in two flavors: detached garages behind older Craftsman homes and attached garages on the mid-century ranches. Each has its own wiring challenge. Detached garages need conduit trenched or run overhead, which adds cost and sometimes triggers the city’s review if the path crosses a root zone. Attached garages are simpler but still need safe routing through walls, crawl spaces, or attics. We handle both, and we’ll walk you through the route before we cut or dig anything.

Trusted Brands We Service in Claremont
We work with the equipment Claremont homeowners actually buy: Tesla, Enphase, SolarEdge, SunPower, Panasonic, Qcells, and FranklinWH. If you’ve already got a charger or a solar system from one of these brands, we’ll integrate with it cleanly. We keep common parts stocked on our trucks so a Claremont call doesn’t turn into a two-week parts wait. Most jobs are done in a single visit.
Common EV Charger Installation Problems We See in Claremont Homes
- 100-amp panels tripping the main breaker. A Level 2 charger pulling 48 amps during a July heat wave when the AC is maxed out will trip the main on an older Claremont panel. The fix is a service upgrade, and we’ll tell you exactly what that costs.
- Conduit routes rejected by the city’s arborist review. Claremont’s tree ordinance protects mature oaks and jacarandas, and if your charger conduit risks root damage, the city can reject the plan. We design routes that avoid root zones from the start.
- Heat derating on south-facing garage walls. Claremont regularly hits 100°F-plus in summer, and a charger mounted on a south-facing wall in direct sun can derate and throw intermittent faults. We position units where they’ll stay cooler or spec hardware rated for the heat.
- Detached garages with no existing subpanel. Many older Claremont homes have detached garages that were never set up for heavy electrical loads. Running a proper circuit means trenching, conduit, and a subpanel, which adds cost but prevents a fire hazard.

FAQs - EV Charger Installation in Claremont
Most Claremont homes built before 1980 have 100-amp electrical panels, and a Level 2 charger pulling 48 amps on top of a central AC system in a Claremont summer will push that panel past its safe limit. We see this constantly in the Craftsman homes near the Village and the mid-century ranches throughout the residential neighborhoods. The charger itself is fine; the panel is the bottleneck. A panel upgrade in Claremont typically runs $2,800 to $4,500, and it’s often required before the city or your utility will sign off on the charger. Call (877) 550-6892 and we’ll check your panel’s actual rating and capacity before you spend anything.
Claremont actively protects its mature tree canopy, including coast live oaks and jacarandas, and that protection extends to their root zones. If your charger’s conduit would pass through a protected tree’s root zone, the city can reject the plan during permit review. That means we have to route conduit around trees, which sometimes adds a few feet or changes where the charger lands on the wall. It’s a Claremont-specific complication that installers working in Pomona or Ontario rarely encounter, and it’s one of the reasons a local crew matters here. We’ll walk your property, identify protected trees, and design the route before we file anything.
Yes, and it’s one of the smartest things a Claremont homeowner with solar can do. Claremont sits at roughly 1,100 feet elevation at the foot of the San Gabriel Mountains, and summers regularly hit 100°F-plus. That means your AC is working hard, your panels are producing well, and your EV is adding a new load on top of it all. Pairing the Wall Connector with a solar system and configuring it to charge during peak production hours keeps that new load from hitting your utility bill at the highest rates. We’ve done this for Claremont homeowners with Enphase, SolarEdge, and SunPower systems, and the integration work is usually $400 to $900 on top of the charger install.
South-facing walls in Claremont get direct sun all afternoon, and in July and August that wall can easily reach 130°F or more. Older charger hardware and some mid-range units will thermally derate, meaning they throttle charging speed or shut down intermittently to protect internal components. We see this with chargers that were installed by homeowners or handymen without considering Claremont’s specific heat profile. The fix is usually repositioning the charger to an east or north wall, or spec’ing hardware rated for sustained high temperatures. If your charger has been acting up on hot afternoons, that’s the likely culprit.
The older the home, the more likely the panel needs work. We see the most service upgrades in the Craftsman bungalows south of the Village where homes often still have original 100-amp panels, and in the mid-century ranch neighborhoods off Indian Hill Boulevard and Mountain Avenue where panels were sized for a 1960s electrical load. The larger custom homes on the north end near the Claremont foothills sometimes have 200-amp panels already, but not always. The only way to know for sure is to look at the panel. We’ll come out for free, read the label, check the actual loads, and tell you whether a charger will work with what you’ve got. Call (877) 550-6892.
Call Gus’s Solar for EV Charger Installation in Claremont
We talked earlier about a 1950s ranch home near the foothills. The homeowner had a 100-amp panel, a Tesla Wall Connector in the box, and a protected coast live oak growing right where the charger should have gone. We upgraded the panel, ran conduit along an exterior wall beside the oak’s root zone, and landed the charger on the east-side garage wall where it stays cool and clear of the tree. The homeowner now charges overnight while their solar system offsets the added load. That’s the kind of problem Claremont throws at you, and we’ve been solving it here long enough to know the moves.
If you’re in Claremont and you’re thinking about an EV charger, call us before you buy anything. We’ll give you a real price, a real timeline, and a straight answer on whether your panel can handle it. Bring me a bill, I’ll bring you the math. Call (877) 550-6892 today. A live person answers, 24/7. No pressure, no signature tonight, no surprises.
