EV Charger Solar Calculator

Calculate the solar array size needed to offset your electric vehicle charging.

EV Battery Capacity (kWh)

Daily Miles Driven

EV Efficiency (mi/kWh) Typical: 3.0-4.0 mi/kWh

Charger Type

Charging Efficiency (%) Typical: 85-95%

State/Location

Panel Wattage

EV Charging Formula


                        Daily kWh = (Daily Miles / Efficiency) / Charging Eff

                        Solar kW = Daily kWh / Sun Hours / 0.80

                        Panels = Solar kW / Panel Wattage
