PV어레이의 발전성능 예측을 위한 모델링

One of the most promising renewable energy technologies is photovoltaic(PV) power. PV systems are turly elegant means of producing on-site electricity from the sun without noise, pollution or any moving parts. It is estimated that one hour of solar energy received by earth is equal to the total amount of energy consumed by humans in one year. However many PV systems are not installed in suitable part which is concerned about geometrical factor. It is generally recognized that the actual output of PV system in field is a function of orientation, tilt angle, irradiance, temperature, soiling and various system-related losses. Thus in this paper, based on the electrical characteristics of PV module, a simple model is proposed to predict the PV module performance for inexperienced engineer and architecture. Five factors are introduced in this model to account for the complex dependence of the PV module performance upon irradiance and temperature. this model is simple and useful for architecture and engineer to calculate the electrical power of PV module under operating conditions.
