Abstract
Generally there are two types of solar tracking, blind and sensitive; the sensitive solar tracking system is based on the sun-pointing sensor detector. In this work we will study a proposal of a new sun-pointing sensor detector, In order to have a sun tracking device, who tracking the sun with reliability and accuracy throughout the year in an optimal way. Before starting the phase of realization, it is important to have an idea about the behavior of the proposed detector, for that we started with a detector design using SolidWorks, after that we have introduced the designed detector in optical simulation software 'TracePro'. The obtained results have shown that the proposed detector is reliable, with few problems during system startup in the winter where we have proposed some solutions.
