For those with solar roofs, using solar power to charge their electric vehicles is a money & energy-saving endeavor. Charging an electric car by using your own rooftop solar power is easy, but it depends on several factors, most notably the size of the solar system, time of day and weather. The problem arises because in cloudy or inclement weather the solar system often cannot generate enough power to cover the charger at full power. Fortunately, that's where our Injet Swicpower can help on your need.
