Solar power is environment friendly power source, but it is characterized by being highly
dependent on the irradiation level which is function of the sun position in the sky. To
overcome this situation and extract maximum power from the sun, the PV array must be kept
nearly perpendicular to the sun during the daytime. In this paper, a smart relay based sun
tracking system has been designed and implemented to keep the PV array perpendicular to
the sun during the day hours.
