Modeling the performance of several photovoltaic modules

The model equations to estimate the photovoltaic module performance for outdoor were proposed by many institutions. This work proposes the new model, which is the high predictive accuracy on low irradiance, combines the model proposed by National Renewable Energy Labonatory (NREL) and the model proposed by Joint Research Centre (JRC); meanwhile, we estimate the photovoltaic module performance using the linear interpolation method, which is being deliberated at the conference that International Electro technical Commission (IEC) sponsor. This paper describes the new model, and a result of comparing both models which adopted several photovoltaic mod es; a crystalline silicon module (c-Si), a polycrystalline silicon module (poly-Si), and a cupper-indium-diselenide module (CIS).
