In the situation of expanding domestic solar power supply business long-term performance modeling of a proposed solar-cooling and cleaning system to increase electromotive force and light transmission is carried out to test the effectiveness of the system. To test the effectiveness of the system, the data which comparing the solar power planet installing the system to not installing at the same time is used. A difference between the capacity factor of each comparison group were recorded. Approximately from one year Field Test was performed, Result of apply to cooling/cleaning technology, Each of plant by From least 6.4 percent up to 11.5 percent capacity factor increased, and the cooling/cleaning is output through improved as a result of the determined.

태양광 발전은 일사량이 높을수록 발전량이 증가된다. 그러나 일사량이 높아짐에 따라 셀의 온도도 같이 증가하여 발전효율은 감소하게 된다. 일반적으로 태양광 셀(Cell) 표면의 온도를 1℃ 감소시키면 약 0.5%의 발전량의 증가가 있다고 알려져 있다. 본 논문은 태양광 발전량 증가를 위해 냉각/세정 장기 실증 실험을 수행하였다. 기전력과 집광량을 높이기 위해 모듈 표면 온도를 낮추고 오염물질을 제거하는 냉각/세정 기술을 이용하였다. 실험 방법은 냉각/세정 설비가 설치된 곳과 설치되지 않은 곳의 이용률을 비교하였다. 장기 실증 시험을 결과 냉각/세정 설비의 구동으로 인한 발전량이 최소 13%에서 최대 19%까지 증가하였다. In general, the solar photovoltaic power increases with higher solar insolation. However, the solar cell generation efficiency reduces because the solar cell surface is heated by solar insolation. According to advanced research, with a 1°C increase in the solar cell surface temperature, the generation efficiency decreases by ~0.5%. To solve this problem, we conducted experiments in which we attempted to reduce the solar cell surface temperature using a water jet spray. In this study, we found the long-term experimental results of increases in solar power generation. The experimental results show a comparison of the site with and without cooling and cleaning equipment being installed. The results of the long-term experiments show that solar photovoltaic power generation is increased by at least 13% up to 19% with cooling and cleaning.
