Patent attributes
A solar power system. A plurality of solar cells are joined to a foldable base. The foldable base has areas between the solar cells configured to fold to enable stacking of the solar cells. A voltage regulator is coupled to solar cells and an electrical connector is electrically coupled to the voltage regulator and configured to electrically couple to, and deliver an electric current to, an electrical device. In implementations a reflector is coupled to the foldable base adjacent to one or more of the plurality of solar cells, the reflector including a reflective material on a face of a flexible material, the reflective material configured to reflect light towards one or more of the plurality of solar cells. In implementations the voltage regulator is a pulse width modulation (PWM) voltage regulator. In implementations a switch coupled to the voltage regulator adjusts the voltage output between two or more levels.
