Abstract: A reliable solar powered sign system is disclosed and claimed. The solar powered sign system includes an electric sign, a solar array, and a pair of battery banks. The battery banks are generally coupled a control unit. The control includes a first charge controller, a second charge controller, and a logic board. The first battery bank is coupled to the first charge controller, and the second battery bank is coupled to the second charge controller. The logic board monitors an operational state of the first charge controller and the second charge controller, and, based on the operational state of the first charge controller and the operational state of the second charge controller, couples one of the charge controllers to the electric sign.

Abstract: A mobile solar power source is disclosed and claimed. The mobile solar power source comprises a trailer mounted housing that includes three solar panels; the first solar panel is mounted on the front of the base housing, the second solar panel is coupled to the left side of the first solar panel by a piano hinge, and the third solar panel is coupled to the right side of the first solar panel by a second piano hinge. A pair of rotatable braces hold the second and third solar panels in place.
