태양 집광판 경사 고정방식과 양축 프로그램 가동방식의 집광능력 성능비교

In the present study, the photovoltaic generation performance is compared for the fixed module and the 2-axis operation module in a solar tracker. Two units of 170 W PV(Photovoltaic) module are installed in a row. It is found that the photovoltaic generation performance of the tracking system is higher than the fixed module regardless of the insolation. The photovoltaic performance for the 2-axis tracking module becomes 24.7% higher than that for the fixed module when the insolation is 6177.77 Wh/㎡. And the system efficiency enhancement of tracking system is 24.70 % when the insolation is 6177.77 Wh/㎡. As the insolation increases, the module surface temperature also increase leading to the reduction of photovoltaic generation efficiency.
