摘要：

As an evaluation method of the photovoltaic (PV) system, it is necessary to clarify loss factor which decreases system efficiency. One of the factors mentioned is the reflection loss that depends on an incident angle. It is believed that the factor is simulated by reflections and transmissions in a module. Using the optical performance of a four-layer encapsulation, a simulation was made on the reflection loss according to Fresnel's law. Further, the incident angle modification factor as the coefficient for evaluating energetic reflection loss was described by a computer program simulation. The result was that the modification factor is between 0.96 and 0.98. Consequently, to obtain the optical property of module materials, the module tilt angle and its latitude location, the simulation could give the evaluation of annual reflection losses by such a factor at various regions.
