Pv carport is a system combining pv power generation with carport, which has great flexibility and can be used for commercial and residential areas. The whole structure is made of aluminum and the fasteners are stainless steel. It can not only shelter vehicles from wind and rain, but also use solar energy to create clean photovoltaic energy for electric vehicles to charge, light and connect to the grid. The system has almost no geographical limitations and is very flexible and convenient. Double column support, parking on both sides of the carport, can make good use of the parking area.
