The future is here. It is entirely feasible to run your electric car off solar energy instead of fossil fuel-generated grid electricity. That said, it will require additional power and panels. Electric car batteries range from about 30 – 100 kWh. Consider your driving habits to determine how many kWh an electric car will add to your usage. A helpful figure to remember is that electric cars average about 3 miles per kWh. Be sure to talk to the solar company you work with about any potential large appliance or electric vehicle purchases. They should be able to advise on how future energy use will impact your system.
