2027 Subaru Solterra AWD: home charging cost in Arizona

A 2027 Subaru Solterra AWD draws 28 kWh per 100 miles per the EPA; at Arizona's 15.45¢/kWh residential rate that's $4.32 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 73% less than gas per mile, here specifically.

Getting set up to charge a 2027 Subaru Solterra AWD at home

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Arizona electrician to quote the install before this math becomes a real decision.
