Panel Upgrade (100A to 200A) in Atherton

Permits in Atherton go through the Town of Atherton Building Division, which typically processes EV charger applications in 5–14 business days. We submit the load calculation per NEC 220.87, panel schedule, and one-line diagram with every application — getting most installs approved on the first review. We schedule the final inspection on your behalf and you don't need to be home for it.

Atherton sits in one of the highest EV-adoption markets in the country, with high EV penetration and growing fast. Highest median home price in US (consistently). Tech billionaire enclave. Large wooded lots with long driveways — trench runs often 100+ ft. Multiple car EV garages common. Tesla Powerwalls and solar + EV integration popular. High-touch clients expect premium service. The local utility, PG&E, offers EV-specific time-of-use rates that cut overnight charging costs roughly in half — most ChargeWizards customers in Atherton pay about $0.30–$0.40/kWh during off-peak hours, or roughly $1.20 per gallon-equivalent for an EV.

ChargeWizards has installed panel upgrade (100a to 200a) in homes across Atherton — from single-family estate homes with 200A panels to newer construction with 200A service. Every install includes a free pre-quote panel assessment (so we never quote a panel upgrade you don't need), the city permit, dedicated 240V circuit, mounting, commissioning with the charger app, and final inspection coordination. Our owner is on every job — no subcontractors, no rotating crews. CSLB C-10 #1134931, fully licensed and insured.
