Renewable energy solutions are becoming increasingly popular, solar power is one of the most powerful renewable energy. Maximizing power output from a solar system is desirable to increase efficiency. In order to maximize power output from solar panels, one needs to keep the panels aligned with the sun. In this paper, a prototype for a microcontroller-based dual-axis multi-function solar tracking system is designed, which will keep the solar panels aligned with the sun in order to maximize the power generation. This system is designed using micro-controller, light sensors, gear system and motors. This tracking system has additional function such as cloudy day assist. The solar tracker, a device that keeps photovoltaic or photo thermal panels in an optimum position perpendicularly to the solar radiation during daylight hours, can increase the collected energy by up to 50%. Commercially; single-axis tracking mechanisms are available. Usually, the single axis tracker follows the Sun’s East-West movement. The model of dual axis tracking is introduced in order to track the sun both in north-south axis as well as in east-west axis. This is possible by constructing the solar panel mount to rotate over both the axis, in this prototype the mount base is made to rotate in north-south direction and the head of the mount is made to rotate in the east-west direction. Zero cross detection method is using to track the sun; in this dual axis method two zero crossing detection are used to track sun in all directions. Zero cross method means comparing two LDRs values to find maximum light source.
