Design and construction of a fuzzy logic dual axis solar tracker based on DSP

Abstract

Solar energy has been accepted as an alternative source of energy worldwide recently. Current researches and markets have shown that Solar Photovoltaic (PV) is the fastest growing and most promising form of renewable energy used in generating electricity. Solar energy is rapidly advancing as an important means of renewable energy resource. More energy is produced by tracking the solar panel to remain aligned to the sun at a right angle to the rays of light. This paper presents an intelligent sun tracking system in which photo-resistors (sensors) are used to determine the direction of the sunlight. The hardware structure of the system consists of a TMS320F2812 DSP chip. The solar cell is used as the power supply of the controlling system. Finally, an intelligent solar power plant is implemented by means of the techniques mentioned above.
