Final Results

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.

  1. What is the torque of unipolar stepper motor you used
    Please give details about this project at my email.l faced some problems in this project please help me

  2. Can I take all this project
    I need this for my graduation project
    I need the code and the program used it
    And circuit design
    And system building

  3. I was just wondering what code you used for this and how did you go about designing the gear for it to move? If you could email me the details? That would be greatly appreciated, I’m designing a solar panel for camping in the summer time and being able to hook up a trailer and it would be great to have an idea of how to put this together.
