P-V Characteristics According to the Module Temperature

모듈온도에 따른 전압-전력 특성

Development of renewable energy is promoted to achieve sustainability. So researchers are seeking and developing a new, clean, safe and renewable energy. 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 power vary with module temperature, it is necessary to study the characteristics of photovoltaic P-V according to the external factors. This paper presents the analysis of characteristics of photovoltaic P-V according to the module temperature. The results show that it seems that when the module temperature increases, the DC power increases. But actually, because when the irradiation increases, the DC power increases, the result of the relationship between DC power and the module temperature of solar cell will be effects by the increasing irradiation.
