Can Solar Panels Save Money on EV Charging?

An electric vehicle increases household electricity use, but whether that improves the value of solar depends on where the car is parked during sunny hours and your charging tariff.

Start with the fair vehicle comparison

Compare the electric vehicle price premium against a similar petrol vehicle and account for fuel saved, kilometres travelled, electricity consumed and charger installation.

Charging times change solar savings

A car charged at home during daylight may use solar that would otherwise be exported. A commuter car charged exclusively at night will usually need grid electricity or a sufficiently sized home battery.

Test combinations, not isolated gains

Calculate EV-only, solar-only, solar-plus-EV and battery combinations on the same energy model to avoid double-counting avoided grid imports.
