Solar energy is one of the major renewable sources and is non polluted. Hence, the utilization of this energy is essential everywhere where the maximum possibility of utilization of solar energy is there. One of such possibility is solar power to street lights and traffic systems. Hence, an attempt is made to implement the solar power saver system for street lights and automatic traffic control unit. The proposed system is implemented with MAX3032 Altera CPLD with 32 macro cells. An infrared sensor array is installed on the streets to know the presence of traffic. As there is a requirement of light only at night times, light detectors are used in the system to work it only in the absence of sun light when there is a presence of traffic. In this way the maximum power can be saved. Proposed cost effective system not only saves the power rather it reduces the usage of conventional energy. The proposed system logic is implemented using VHDL.
