Abstract: Shading is common phenomenon when Solar Photo Voltaic (SPV) panels are put into actual service conditions. Shading reduces insolation and efficiency of the array. In this work, the Current - Voltage (I-V) and Power-Voltage (P-V) characteristics of 6-panel SPV array is investigated for six different shading patterns. “n” Number of steps and “n” maximum power points occurred in the curves when array received “n” different levels of insolation.
