Electrical Panel Upgrade Cost in Arizona
The panel upgrade is Arizona's most-quoted and least-understood electrical job — partly because EV chargers, ACs, and solar all funnel into it. This guide breaks down what the job actually involves, a realistic Arizona price range, and the line items that make one quote double another.

Reading the bids
Only hire a contractor whose ROC license you've checked — it takes two minutes: how to verify an Arizona electrician's license. Browse licensed electricians near you, and if the panel is feeding a new EV circuit, read the EV charger install cost guide so you can price the whole job at once.
Frequently asked questions
Do I need a permit to upgrade my panel in Arizona?
Yes — panel changes and service upgrades require a permit and inspection in every Arizona jurisdiction, plus utility coordination for the service disconnect. A contractor who suggests skipping the permit is a red flag.
Do I really need 200 amps?
Not always. Load calculations sometimes show a 100–125A service handles a home fine until you add big loads (EV charger, spa, electrified heat). A good electrician runs the load calc before quoting the upgrade.
