EV cost assumes a 2026 Chevrolet Equinox EV FWD (31.1 kWh/100 mi, EPA) charged at home at the state average price. Panels assume 400 W each sized to cover average annual use. Methodology.
Estimates only. Your actual costs depend on your utility's rate plan, how and when you charge or use power, and local prices. This is general information, not financial, tax or legal advice. See our disclaimer.
