摘要：

The authors have studied the diagnosis method of PV systems. In this paper, influences of partial shadow reflected partly on PV panels on the electrical characteristics of solar cells are numerically investigated by using the LT Spice simulation. Not only the change in I-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 clearly illustrated that the cell with the lowest transmission of sunlight among the cells concerned dominates the whole characteristics of the PV module. Numerical results obtained from the current simulation will provide basic knowledge when estimating the total I-V characteristics of a whole PV system which composed of multiple PV subsystems having different I-V characteristics with each other.
