For the dual axis rotation we propose the arrangement mentioned in the diagram below.
The system is implemented using Atmel IC AT89C51. The circuit design for the system would be:
Dual Axis Solar Tracker project is to provide an efficient solar distributed generation system. At maximum, the solar tracker is perpendicular to the light source. The built system has a calculated annual energy gain of 48.982% compared to an immobile solar panel. Compared to a single axis tracker, the dual-axis tracker has an annual energy gain of 36.504%.
The purpose of a solar tracker is to accurately determine the position of the sun. This enables solar panels interfaced to the tracker to obtain the maximum solar radiation. With this particular solar tracker a closed-loop system was made consisting of an electrical system and a mechanical system with the help of electronics.
