Looking into adding solar panels to power my home. With all of the talk about the impact of EV on the utility grid, it would make since to expand the capacity to have enough capacity to charge an EV. Does anyone have an idea how and what size of a system I would need to charge an EV? 1Kw, 5Kw, etc Battery switch so that it charges during the day or can the energy be stored and charge my EV battery at night? Thanks for your insight.
