| 内容記述 | Influences of a partial shadow reflected on PV modules on their electrical characteristics are numerically investigated by using the LT Spice simulation and the results are discussed. Not only the change in I-V and P-V characteristics but also the change in current and voltage distribution for every cell component are demonstrated and discussed based on the numerical results. It is illustrated that the output current from a PV module is directly determined by the photo-current of the solar cell which has the lowest transmission ratio of solar irradiation under various shadow conditions, and the maximum power significantly depends on the shadow condition. It is also pointed out that the cell with the lowest transmission level among the cells concerned dominates the output characteristics of the PV module, and the diode currents concentrate to the cells which have the highest transmission level. The reverse current flows toward the modules that have a short-circuited BLDs; namely, those modules are charged from the normal modules. Those results imply the high risk of damage attributed to those reverse currents could be happened in the given PV modules. It is also indicated that the double peaks take place in the P-V characteristics, depending in the shadow transmission levels. Based on this result, it is pointed out that the voltage that corresponds to the maximum power point dynamically changes, depending on the shadow transmission levels. | |||||
