A charging station for electric vehicles includes a solar array for converting solar energy into electricity. A curved column is provided for holding the solar array at an upper end of the column. Its lower end is affixed to a platform for stability. An equipment enclosure is attached to the upper end of the curved column for holding electronic and mechanical components that, respectively, collect and store solar energy from the solar array and operationally move the solar array for this purpose. Additionally, a control unit is included with the electronic and mechanical components in the equipment enclosure to monitor vehicle charging operations. For protective purposes, the equipment enclosure is located on the curved column at an elevated height above the stability platform, to prevent flood damage and avoid theft or vandalism.
