ABSTRACT:
An improved solar lighting system can be applied to a number of temporary signs and is particularly adapted for use on a real estate sign. The system includes three parts: a solar generating unit containing a repositionable array or photovoltaic cells, electronic circuitry and storage batteries; an illumination unit containing electric lamps and reflectors and attachment devices for connection to a variety of signs; and a connecting cable for safely conducting electric energy between the units and for providing device security to discourage theft.
