PANSAT has a total of eighteen solar panels attached to its outer surface. Seventeen of these panels consist of silicon solar cells. The eighteenth solar panel is made of gallium-arsenide (GaAs) solar cells. The high-efficiency GaAs cells are used on the 18th panel due to area limitations. The silicon solar panels are square with dimensions of 7″ x 7″ while the GaAs panel is circular with a diameter of 5.75″. The eighteen solar panels are connected to the Electrical Power Subsystem (EPS) in parallel. The EPS stores power in two batteries. Each battery consists of nine, commercial nickel-cadmium cells.
