Abstract
A solar tracking generating power system is designed and implemented. An expert controller, sensors andinput/output interface are integrated with a tracking mechanism to increase the energy generation efficiency of solar cells. Inorder to track the sun, cadmium sulphide light sensitive resistors are used. To achieve optimal solar tracking, a fuzzyalgorithm is developed. A field programmable gate array is applied to design the controller such that the solar cells alwaysface the sun in most of the day time.The needs for increasing the power generation make the use of solar cells plays animportant role in the daily life. For this reason, it is important to use solar tracking systemto increase or getting almost optimum amount from solar cells. In this paper, proposedintelligent controllers were designed and used to make solar cells facing the sun over theyear.
