Design & Fabrication of Gravity Based Solar Tracker Applied on Scheffler Reflector

A power free solar tracking system has been developed. The proposed system is suitable for 6 hours of continuous cooking. The system altitude has been fixed which avoids changing the system angle for different seasons. The azimuth angle has changed through the gravitational potential energy stored in a water container. The water container is connected to a pair of springs. Discharge of water from the container at a consistent predetermined charge drives the timing belt. The timing belt was established on semi-circular bar of Scheffler cooker. This mechanism allows the Scheffler cooker to rotate with the sun at a uniform rate.
