Highway Signing and Signal Lighting Using Solar EnergyStatus: CompleteReport Date: 04/27/2001 Summary: The operation of traditional highway signing and traffic signals requires the availability of commercial power. Lighting systems that can operate on alternate power sources, such as solar energy, can provide an alternative to line powered systems. Solar energy systems, known as photovoltaic (PV) systems, are especially well suited to locations where accessing an electrical grid is either not feasible or is too expensive. This document discusses photovoltaic products which make use of solar energy to power highway signs and signal lights in remore areas.
