Review the home's electrical load
We run a load calculation on the existing panel before work begins. If capacity is tight, the proposal identifies whether the home needs a panel upgrade or load-management hardware.
EV Charging
Charge your car on power you make.
A Level 2 charger fills your EV overnight or on daytime solar — far faster than a wall outlet. We install home chargers across Southern California, and because we also do solar and battery, we can wire it to run on your own energy instead of peak-rate grid power.

Why homeowners choose OC Solar
Level 2 — overnight full charge
A 240-volt Level 2 charger adds many times the range per hour of a standard outlet, so you wake up to a full battery.
Charge on your own solar
Because we install solar and storage too, we can size and wire your charger to run on daytime solar instead of expensive grid power.
Licensed, code-correct wiring
Dedicated circuits, load calculations, and panel work done to code by our in-house crews — under our CSLB-licensed contractor (#1023627).
Pairs with Powerwall
With a Powerwall, you can charge from stored solar and keep essential charging available during an outage, all managed in the Tesla app.
From panel to parking space
A charger installation starts with the house, not the hardware.
The charger is only one part of the scope. Panel capacity, circuit distance, parking position, permits, and the vehicle all shape the installation. OC Solar reviews those pieces before work begins so the electrical plan is clear.
Electrical work is completed under OC Solar's contractor license, CSLB #1023627. The estimate identifies charger, circuit, panel, and load-management scope before scheduling.
Plan the circuit and parking path
The scope accounts for the distance from the electrical panel to the parking location, the dedicated circuit path, and where the charging cable needs to reach the vehicle.
Place and install the equipment
The charger is mounted where it works for the garage or driveway, then wired on a dedicated 240-volt circuit by OC Solar's licensed electrical team.
Permit, inspect, and hand off
OC Solar handles the permit and inspection for the installation. Final commissioning follows the selected charger's requirements so the system is ready for the vehicle and charging schedule.
Plan the charging window
Fuel the car when the energy makes sense.
Solar and time-of-use rates create different charging windows. The best schedule depends on when the vehicle is home and the utility plan at the address—not a one-size-fits-all promise.
Daytime
Use solar while it is being produced
When the car is home during solar hours, scheduled charging can use production from the roof instead of sending that energy to the grid first.
4–9 PM
Avoid the evening peak when you can
Common California time-of-use plans make the evening peak a poor default charging window. The exact schedule should follow the utility plan at the address.
Overnight
Use the plan's off-peak window
If daytime solar charging is not practical, scheduled overnight charging can move the load outside the evening peak. Rates and hours vary by utility and plan.
One home-energy plan
Tell us how far you drive and when the car is home.
Those two details help connect the charger to the larger energy plan: whether daytime solar can cover charging, whether overnight off-peak charging is the practical default, and whether solar or battery capacity should be considered at the same time.
Connector and vehicle fit
Match the charger to the vehicle—and the house.
Compatibility is more than the plug. We confirm the vehicle, selected charger, parking position, cable reach, electrical capacity, and whether solar or storage is part of the same project.
Tesla vehicles
OC Solar installs Tesla Wall Connector equipment. We confirm the exact vehicle, charger, parking location, and electrical scope before the proposal is finalized.
Connector fit
We install compatible Level 2 equipment for vehicles using NACS (SAE J3400) or J1772. The exact connector, charger, and any adapter requirement are confirmed against the vehicle before the proposal is finalized.
Solar and battery households
If solar or storage is part of the project, we plan the charger as a real household load so the electrical design and charging schedule work together.

Good questions
EV Charging FAQ
Level 1 uses a standard 120-volt outlet and charges slowly — fine for plug-in hybrids but slow for full EVs. Level 2 uses a dedicated 240-volt circuit and charges several times faster, typically filling an EV overnight.
Yes. With solar you can charge during the day on power you generate; with a battery you can also charge from stored solar after sundown. We'll size the system for your home plus your car's typical mileage.
Sometimes. We run a load calculation on your existing panel first. If there isn't enough capacity, we'll either recommend a panel upgrade or use load-management hardware — and we'll tell you which before any work begins.
We install the Tesla Wall Connector for Tesla vehicles and universal Level 2 chargers with the J1772 connector for other EVs, wired to code by our in-house electricians.
Yes — in most cases we can add a Level 2 charger to a home that already has solar, after confirming your panel and circuit capacity. If you're also considering a battery, tell us at the same time: charging from stored solar after sundown is the cheapest way to fuel a car, and planning both at once avoids redundant electrical work.
It depends on the distance from your electrical panel to where you park, your panel's spare capacity, and whether you need a panel upgrade or load-management hardware — the charger itself is only part of the total. We run a load calculation first and give you an itemized price before any work begins. Estimates are free, and bundling with solar lets us size everything once.
Several times faster than a wall outlet. A Level 2 charger runs on a dedicated 240-volt circuit and typically fills an EV overnight, versus the slow trickle of a standard 120-volt plug that suits plug-in hybrids but frustrates full-EV owners. For daily driving, it's the difference between waking up to a full battery and rationing your range.
Not 4–9 PM. Under California's time-of-use rates, the evening peak is the most expensive way to fill a car. The cheap windows are midday on your own solar, from a battery filled by daytime solar, or overnight on off-peak rates — and most EVs and chargers can schedule charging automatically. We size and wire the charger so those cheap windows actually cover your driving.
