Fast, Reliable EV Charger Installation Across Ontario
Most Ontario homeowners want to know two things: how much will an EV charger installation cost, and how soon can it be done. A Level 2 charger install in Ontario typically ranges from $450 to $1,100 when your existing electrical panel has spare capacity, and $2,400 to $4,800 when a panel upgrade or subpanel is required. We’re in Ontario every week, and we can usually be at your door within 48 hours for a quote. Call (877) 550-6892 and a live person answers, day or night.
The bigger question in Ontario is what your house will actually need. That answer depends on which side of the 10 Freeway you live on. We’ll get into that below, because it changes everything about your final price and timeline.
Why Gus’s Solar Is Ontario’s Preferred EV Charger Installation Company
Gus Petrakis has been running a local shop in the Inland Empire since 2011, and his name goes on every truck, every invoice, and every permit we pull in Ontario. We are not an out-of-state call center that subs your job to whoever picks up the phone. The crew that gives you the quote is the same crew that does the work, and they are background-checked and uniformed.
Ontario homeowners tell us the same thing after working with the national outfits: the estimator was sharp, the install crew was a stranger, and nobody ever came back when something stopped working. That is not how we operate. Our 90-Day Done Right Promise applies to every EV charger installation. If something is not right, Gus comes back and makes it right, in writing, on every job.
Our office handles scheduling for Ontario locally, so a 45-minute response window is realistic for most of 91762, 91764, and the Ontario Ranch side of 91761. We know the HOAs. We know which panels the 1980s tract homes in 91762 shipped with. We know the inspectors at the city’s building department. That local knowledge is the difference between a two-week install and a two-month headache.
Our EV Charger Installation Services in Ontario
Here is what we actually install in Ontario, broken down by the jobs we do most often. If you are not sure which one fits your situation, call us. A five-minute conversation usually answers it.
Level 2 Charger Installation
This is the standard 240-volt charger that adds roughly 25 to 30 miles of range per charging hour. In Ontario, most homeowners go with a 40-amp or 50-amp circuit, which covers every EV on the market today. The install itself is straightforward when your panel has room, and we can typically complete it in a single visit. If your panel is tight, we will tell you before we start, not after we have opened the wall.

Tesla Wall Connector Installation
We install more Tesla Wall Connectors in Ontario than any other single charger model, and for good reason. Tesla owners in 91761 and 91764 want the full 48-amp output, which means a 60-amp circuit. In a new Ontario Ranch home that is usually doable. In a 1980s tract home off Euclid Avenue or Holt Boulevard, it often triggers a panel upgrade. We will quote the charger and the panel as two separate line items so you know exactly what you are paying for.

Panel Upgrade for EV Charging
This is the quiet cost driver in Ontario. Homes built between the 1970s and early 1990s in the 91762 and 91764 ZIP codes frequently still have 100-amp main panels. Add an EV charger pulling 40 or 48 amps, and you are over budget the moment your air conditioning kicks on during a 105-degree August afternoon. We replace old panels with 200-amp service, handle the city permit, and coordinate the meter spot with Southern California Edison. The work is done by Gus’s own crew, never a sub.

Garage & Driveway Charger Wiring
Some Ontario garages have a subpanel that is already nearly maxed out, especially newer Ontario Ranch homes where the Title 24 solar inverter and a tankless water heater are already pulling from it. We run new circuits from the main service panel, route conduit cleanly, and match the existing finish so it does not look like an afterthought. For driveway chargers, we trench to code, install the pedestal, and make sure the conduit is rated for direct burial.
We also handle EV Charger Installation work that pairs directly with solar, which brings us to the next point.

Solar-Paired EV Charging: The Ontario Play
A EV charger that pulls from your solar system changes the math on your true-up bill. But in Ontario, you have to think about when you charge, not just what you charge. Our inland location means summer air conditioning demand peaks in the late afternoon and early evening, right when a lot of people get home and plug in.
If you have a solar array and you are considering an EV charger, we will ask to see your last true-up statement. Not your month-one utility bill from 2016. Your actual current usage. Then we size the system so your EV charging does not wipe out your net metering credits during peak cooling hours. That’s the conversation a national outfit usually skips. We don’t.
For Ontario Ranch homeowners whose panels were already installed under Title 24, the conversation is different. Your system was likely sized for the home’s baseline load, not an EV. Adding a charger may mean adding a couple of panels or a battery. We can wire the charger now and design the solar expansion later, or do both in one permit pull to save on fees.
Trusted Brands We Service in Ontario
We work with the equipment already on the market and in Ontario garages: Tesla Wall Connector, ChargePoint Home Flex, Enphase, and SolarEdge EV chargers, among others. We also regularly service solar installations built on Qcells, REC, SunPower, and Panasonic panels, and we tie EV charging into those systems cleanly. Because our office is local, we keep common breakers, disconnects, and charger hardware in stock, which means we are not waiting on a FedEx truck before we can finish your install.
Common EV Charger Installation Problems We See in Ontario Homes
- The 100-amp main panel surprise. Older tract homes in the 91762 and 91764 ZIP codes often still run on a 100-amp service. Install a Level 2 charger without checking the panel first, and you will find out the hard way when the main breaker trips on the first 100-degree afternoon.
- HOA design review in Ontario Ranch. In 91761, most HOAs require design review for conduit routing and charger placement before you can pull a city electrical permit. Miss that step and you will get a violation notice and pay to re-route the wiring.
- Maxed-out garage subpanels in newer Ontario Ranch homes. The builder’s 100-amp subpanel often already has the Title 24 solar inverter, a tankless water heater, and the washer/dryer on it. There is no room left for a 60-amp EV circuit without running back to the main panel.
- Solar true-up math that ignores EV charging habits. Charging during summer peak hours in Ontario’s inland heat means your EV is pulling from the grid when your panels are producing less than your AC demands. Your true-up bill jumps, and you are scratching your head. This is fixed with a battery, a smarter charge schedule, or both.
Pricing for EV Charger Installation in Ontario, CA
Here are real numbers for the Ontario market. A basic Level 2 charger installation with a short wire run and spare panel capacity runs $450 to $800. A Tesla Wall Connector on a 60-amp circuit, which may require a longer conduit pull, runs $700 to $1,100. Adding a garage subpanel or upgrading a 100-amp main to 200 amps runs $1,900 to $3,200, depending on the panel type and whether the service entrance needs to be relocated. A pedestal-mounted driveway charger with trenching runs $1,200 to $2,400 for most standard lots.
Every quote we give in Ontario is line-itemed. You will see the charger cost, wiring cost, permit fee, and any panel work as separate numbers. We don’t bury panel upgrades inside a vague “installation” line. And we don’t want a deposit tonight. Take two weeks. Think about it. The price will be the same.

FAQs - EV Charger Installation in Ontario
In most cases, yes. Homes from the 1970s through early 1990s in Ontario’s 91762 and 91764 ZIP codes typically have 100-amp main panels. A Level 2 charger pulling 40 to 48 amps will push that panel over its safe capacity, especially during summer afternoons when your air conditioning is running hard. The fix is a 200-amp panel upgrade, which runs $1,900 to $3,200 in this area. We will inspect your panel during the free estimate and tell you the truth, even if the truth is that you can wait a year. Call (877) 550-6892 and we will send someone out.
In Ontario Ranch’s 91761 ZIP, HOA design review for EV charger placement and conduit routing typically adds two to three weeks before the city will issue an electrical permit. Some committees turn it around faster, but two to three weeks is the realistic planning number. Contractors who have never worked inside those CC&Rs often miss this entirely, and the homeowner ends up paying to re-route conduit after a violation notice. We have installed enough chargers in Ontario Ranch to know which locations pass on the first submission. We will handle the submittal and the city permit together so the timeline is not a surprise.
You can, and in Ontario’s inland heat, you should. The trap is charging during peak cooling hours. Your solar system was probably sized for your home’s baseline load, not for an EV pulling 7.7 to 11.5 kilowatts. If you add an EV to existing solar without adjusting your charge schedule or adding storage, your true-up bill will climb. We do solar-paired EV charger installations that include a load-shedding relay or a battery, so the charger draws from your panels when power is plentiful and backs off when the AC is pulling hard. We will size it off your actual true-up statement, not a brochure.
A Tesla Wall Connector needs a 60-amp breaker to deliver full 48-amp charging. In newer Ontario Ranch homes, the wire run from your main service panel to the garage is often the limiting factor, not the panel itself. But the garage subpanel is frequently already maxed out by the Title 24 solar inverter and a tankless water heater, so we may need to pull a new home run back to the main panel. Its a common job for us around the 91761 zip, and we quote it as a separate line item so you see exactly what’s involved.
Yes. The City of Ontario requires an electrical permit for any Level 2 EV charger installation, whether it’s a hardwired unit or a 240-volt receptacle. We handle the permit application, schedule the inspection, and make sure the work passes on the first visit. No permit means no legal installation, and it also puts your home insurance at risk if something goes wrong. We pull permits on every Ontario job, full stop.
One More Thing About Ontario Ranch
If you live in the 91761 ZIP, you already know this, but it bears repeating: in Ontario Ranch, EV charger installations almost always need to clear HOA design review for conduit routing and charger placement before the city will issue an electrical permit. That step does not exist in most of neighboring Rancho Cucamonga or Fontana, and it routinely adds two to three weeks to project timelines for contractors who have not worked inside those CC&Rs. We have. We recently wired a Tesla Wall Connector in a 2021 Ontario Ranch home near the 91761 side of the 15 Freeway, where the builder’s 100-amp subpanel in the garage was already maxed out from the Title 24 solar inverter and a tankless water heater. Our crew pulled a new 60-amp circuit back to the main service panel, then ran liquid-tight conduit across the garage ceiling to the HOA’s preferred wall location, all while matching the existing EMT finish so the design-review committee signed off on the first submission. That is the difference between a local installer who knows the game and a crew that shows up hoping for the best.
