Cost to Charge a Subaru Solterra
Updated September 2026 · U.S. average rates
The short answer: at the national average rate, a full home charge of the Subaru Solterra (71 kWh usable, ~227 miles of range) costs about $13.33 — 5.9¢ per mile, or $58.68 per 1,000 miles. The same charge at a public DC fast charger runs roughly $30.53. Versus a 32-mpg gas car, home charging saves about $39.76 per 1,000 miles.
Living with a Subaru Solterra: the cost story
The Solterra is the bZ4X's all-wheel-drive twin, and standard AWD is genuinely the point: it's the EV for the dirt-road-and-ski-lot crowd, with consumption and charging speed that are both merely adequate.
Its buyers charge at home and value the badge's outdoorsy dependability over spec-sheet wins; on that duty cycle the running costs are quietly excellent versus any gas Subaru.

Subaru Solterra charging speed & home charger
Cost does not depend on speed — a kWh is a kWh — but time does. These estimates use the Subaru Solterra's onboard AC limit (11 kW) and its typical DC fast-charging peak (~150 kW); real sessions taper as the battery fills.
Home charger sizing: the Subaru Solterra tops out at 11 kW on AC, so a 48-amp charger on a 60-amp circuit reaches its limit — a bigger unit adds nothing. Overnight (8 hours) on Level 2 restores about 227 miles, more than most daily driving. See Level 1 vs Level 2 and how many kWh it takes to charge an EV.
