ON-Grid photovoltaic systems represent an economical way to charge an e-car "green" as well.

This is an energy mix from the grid and the electricity of the photovoltaic system during the day.

When the sun is shining, the photovoltaic system supplies the electricity, otherwise the grid.
Thus it is possible to charge the e-car 24 hours a day, this means that the car is ready to drive at any time.
