Abstract: A modular solar generating system is disclosed. The system includes a plurality of self-contained solar modules which are interconnectedly disposed in an array about the perimeter of a rigid framework housing a sign, light, or other load means necessitating electrical power during the night time hours. The modules themselves consist of a photovoltaic plate sandwiched between two suitable cover plates, including in this arrangement one or more continuous conductors. The modules are linked together by way of male and female plug connectors whereby the array may then be electrically connected to a battery. When the modular system is arranged in this fashion and exposed to incident sunlight for an appropriate period of time, power may be provided to a sign, light or other electrical apparatus for nighttime use.
