Abstract

Recently, solar light power generation is widely extended by support policy to regeneration energy. However generation efficiency is decreased when solar module maintain higher than certain point temperature. Therefore, it is need to maintenance under certain point temperature. An method of solving this problem, this paper is developed geothermal exchanger for efficiency improvement of solar cell module. Geothermal exchanger consisted of heat absorber of solar cell module and heat conductor and radiator. Heat of solar cell module is radiated in the earth by geothermal exchanger. An a result, geothermal exchanger is increased generation amount of solar cell module and experiment result showed costs to about 36% increment of generation power.

최근 태양광발전은 정부의 재생에너지 지원책에 의해 널리 보급되고 있다. 하지만 발전효율은 태양전지 모듈이 일정온도보다 높게 유지될 때 떨어진다. 따라서 일정온도 이하로 유지하는 것이 필요하다. 본 논문에서는 태양전지 모듈의 효율을 개선하기 위해서 지열교환장치를 개발하였다. 지열교환장치는 태양전지의 열 흡수판과 열전도판 그리고 방열기로 구성된다. 태양전지 모듈의 열은 지열교환 장치에 의해 땅속으로 방열한다. 결과적으로, 지열교환장치는 태양전지모듈의 발전량을 증가시키며, 실험결과는 발생전력이 약 36% 증가함을 보여 주고 있다.
