Abstract :
The output of solar cell or array depends on the weather conditions such as temperature and insolation level. If the output of the photovoltaic system would be reconstructed under any weather conditions, so it is so easy to develop the inverter and its related system, and also control algorithm. This can be achieved by the VISC (virtual-implemented solar cell) system studied in this paper. A few, I-V curves are provided by the manufacturers, and so any I-V value between the given curves is unknown. The new model for solar cell is proposed, which is based on the interpolation. Both simulation and experiment are executed to show the validity of the proposed VISC system.
