Abstract

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.

본 논문에서는 CPU가 없는 자가동력 태양광 트랙커 시스템을 제안한다. 기존의 태양광 트랙커 시스템은 CPU를 사용하기 때문에 비용과 내구성의 문제가 발생한다. 또한, 기존의 태양광 트랙커 시스템은 설치 장소 및 환경의 영향을 받기 때문에 높은 발전효율을 기대하기 힘들다. 제안하는 태양광 트랙커 시스템은 광 추적센서와 모터의 연동회로를 이용하여 최대의 태양광을 추적하기 때문에 고효율 운전이 가능하고 아날로그 소자들로만 구성되어 있기 때문에 수동소자만큼의 시스템 수명이 보장된다. 또한, CPU를 사용하지 않기 때문에 프로그램 오류로 인한 오작동이 없으며, 설치 이후 유지 및 보수가 간단하다. 제안하는 태양광 트랙커 시스템의 타당성은 1년 동안의 실증 실험 결과를 통해 검증하였다.
