An EV in the driveway makes home charging the obvious next move — and for a solar household, the pairing is the whole point: daytime sun charging the commute. But an EV charger is a serious electrical appliance, and the difference between a clean install and a headache is decided before anyone touches a wire. Here is the homework.
Level 1 vs. Level 2 — the only choice that matters at home
Level 1 uses a standard 120-volt outlet: no install at all, but slow — a few miles of range per hour, fine for short commutes and plug-in hybrids. Level 2 runs on a 240-volt circuit like a dryer or AC unit and charges several times faster — a full overnight recharge for almost any EV. (Level 3 fast charging is commercial equipment; it does not belong in a garage.) Most Arizona EV households end up wanting Level 2, and Level 2 is where the electrical work begins.
Whether your panel can take it
A Level 2 charger typically wants a dedicated 40–60 amp circuit — a meaningful bite of a home’s electrical capacity, on top of the AC load an Arizona summer already demands. Older or fully-loaded panels may need a load calculation, a circuit rearrangement, or a panel upgrade before a charger can be added safely. This is exactly the question a licensed electrician answers before you buy hardware, not after it fails inspection.

A hardwired Level 2 install generally needs a permit and inspection — a licensed contractor handles that as part of the job, and it protects both your insurance and your resale story. Placement matters more here than most guides admit: garage heat is brutal on electronics, so shaded mounting and adequate clearance help the charger last, and cable reach should match where the car’s port actually parks. Buy a charger rated for our ambient temperatures — not every unit is.
The solar pairing
Charging from your own array is real, with one honest caveat: the sun is up when many commuters are at work. What makes the pairing genuinely work is knowing your production and usage patterns — scheduling charging into daylight hours where your lifestyle allows, or simply understanding what share of charging your array offsets. Circuit-level monitoring shows the charger and the solar on one screen, which turns the guesswork into a schedule.
Who should do the install
A licensed electrical contractor — full stop. EV circuits carry real, continuous load, and this is not the corner of the house for handyman pricing. We are a licensed Arizona electrical contractor (ROC #331356) and EV charger installs are part of our Service Department work, especially for solar households where the charger, panel capacity and array need to be planned as one system. Ask us with your panel photo and charger model, and you will get a straight written answer.
