Performance of solar photovoltaic module under partial shading conditions

The design of the solar photovoltaic (PV) module is done by connecting required number of cells in series and shunt to get the desired output, thereby increasing the efficiency. However, the performance of the PV system gets affected by the environmental conditions such as change in solar insolation and temperature. If the solar array be under shaded condition, its output power level decreases. The output voltage also further decreases due to the arise of the local hotspot. This paper presents the experimental simulation study showing the I-V characteristics of PV system under different types of partial shading conditions. The experimental analysis has been performed by using ecosense insight solar PV kit.
