摘要：Due to the rising need for the resources of energy especially in the developing countries, solar energy isgaining importance. This paper presents the extremely low cost and robust dual axis tracking system that positions solarpanel to receive maximum solar energy. Rotation around one axis is automatic and done daily to track the sun whilesecond axis is used for manual adjustment against seasonal variation in the sun path. Database for position of the sun atany point of time from any location on earth is available online. The unique feature of the system is it uses optimizeddatabase of yearly sun position for particular location on earth to track the sun, which enables the system to work evenin the cloudy weather. Light detector sensors are not used otherwise requires cleaning of the sensors as well asmalfunction in cloudy weather which is eliminated. Low cost close loop control system is used to position the solarpanels.
