This tracking system was designed based on the work of operational amplifiers and achieved maximum accuracy by two separate methods and was evaluated using op-amps specifications and comparing for twice the voltage of optical resistors which work is sensing. Optimization numerical results and achieved experiences showed good condition of this type of design. Angled and pyramid layout are used to get sunlight of these resistors; this created angle between the two resistors will raise the navigation accuracy as much as possible. If solar radiation reach the photovoltaic panel with deviation, it can reduce the output efficiency up to 50% and even more. A moment tracking is considered for this system in order to minimize this problem. In this work, it has been tried to prevent the complexity of electronic circuit and also equipment as much as possible. It will reduce the system costs in implementation and construction by raising efficiency and speed of the system response to the sun locational changes.
