Energy management system (EMS) using natural energy such as sunlight is expected to build a low-carbon society. In this paper, we report the modeling of the Si-bifacial photovoltaic (PV) module and the accuracy evaluation of simulation at Hokuriku region where is one of heavy snowing area in Japan. We produce the simulation model of PV power generation using simulation program with integrated circuit emphasis (SPICE). To simulate the generated energy accurately, the global solar radiation is input and the model of the bifacial PV module is fit to actual measured value. Using SPICE model, we simulate and evaluate the generated energy in each season. We conclude that the SPICE model can estimate the PV power generation within 10% of deviation at Hokuriku Region in sunlight day with the exception of winter.
