Can I charge a plug-in car with solar or wind power?

A:

The cleaner the power, the cleaner the car. Using solar photovoltaics (PV) at your home or business makes even more sense with a plug-in car. The investment in solar panels pays off faster when the solar power is not only replacing grid electricity but also replacing much more expensive gasoline. EVs typically can’travel 4-8 km (or more) per kWh of electricity. If you drive 19,000 km per year, you will need 3,000-4,000 kWh. Depending on where you live, you will need a 1.5kW-3kW PV system to generate that much power using about 14-28 square meters of space on your roof.
