본문

This paper proposes the self-powered solar tracker system without CPU. Conventional solar tracker system occurs the problem of

cost and durability because of using CPU. In addition, this system has effects from installation site and environment. The proposed

solar tracker system without CPU is possible to achieve the high efficiency because it tracks the maximum of the light source. The

validity of proposed solar tracking system is verified with experiment results..
