A Novel Design and Experimental Study for a Two-Axis Sun Tracker

In this paper has been tried to optimize the solar energy in a new way according to the increasing importance of renewable energies and a sample biaxial sun tracker is built. There are three algorithms for tracking the Sun: first algorithm, move the plane in circular coordinates in the small ranges, then find the point with the best voltage for its field of work and oriented to that and then repeat it again. Second algorithm, find the slope of the voltage and use it to find its way. Third algorithm is like second but use it to find some appropriate points that are distinctly in different times. It use non linear multi parameter relation with last mean square method for finding the altitude and predict where the Sun will be in the next step. This algorithm, apply this equation to positioning and then verify second algorithm for confidence We attempted to optimize these algorithms and utilize them in our device. The mechanism for this work programmed with a digital program that has been used in the control system. Position of the Sun has been calculated and error points will reveal during routine activities of system.
