EV Savings Calculator
Why keep paying for gas or high utility bills when the sun can power your ride for less? With electric vehicles on the rise, how you charge matters more than ever. This calculator shows you the real difference in cost between fueling with gas, charging your EV from the grid, and charging with solar.
Sunshine is the new fuel. Compare your savings.
Gas Savings For our default calculations, we've assumed a fuel economy of 25 miles per gallon for a comparable gasoline powered car. We've also assumed Hawaii's average of $0.42 per kilowatt-hour for residential electricity (assumed for 100% of charging) and $4.50 per gallon for gasoline. The default EV efficiency value is 3.5/kWh. We've assumed $0.00 per kilowatt-hour for solar power combined with solar storage; however this rate depends on the size and electricity offset of your solar system and storage system. Please use the sliders to update the calculations based on your driving habits, vehicle, and utility cost information.
