The exterior car parts, e.g., roof, doors, hood, trunk and so forth, may include integrated photovoltaic cells, all manufactured in the shape of the corresponding car parts. The photovoltaic cells are meta-encapsulated in an edgeless manner, and may utilize superconducting anodes. A first encapsulate may be polychlorotrifluoroethylene, an extreme water barrier. A second encapsulate, e.g., silicone, may be a water barrier and shock absorber. A third encapsulate may be UV stabilized polycarbonate or low iron glass. A street legal solar car may be constructed upon an electric car chassis. A competition solar car has one or more hyper-efficient electric motors, that may utilize superconducting wire in their armatures. Superconducting wire may also be used in the vehicle chassis.
