모듈온도에 따른 전압-전류 특성

I-V Characteristics According to the Module Temperature

Solar, as an ideal renewable energy, has inexhaustible, clean and safe characteristics. However, solar energy is an extreme intermittent and inconstant energy source. In order to improve the photovoltaic system efficiency and utilize the solar energy more fully, and the DC current vary with module temperature, it is necessary to study the characteristics of photovoltaic I-V according to the external factors. This paper presents the analysis of characteristics of photovoltaic I-V according to the module temperature. The results show that it seems that when the module temperature increases, the DC current increases. But actually, because when the irradiation increases, the DC current increases, the result of the relationship between DC current and the module temperature of solar cell will be effects by the increasing irradiation.
