Abstract

The most promising source of renewable energy is solar photovoltaic (SPV) generation. These SPV modules facing issues with varying environs as well as Partial shading conditions (PSC) of cells in the modules. Normally, for varying PSC of single SPV module maximum power point tracking (MPPT) techniques is quite adequate to overcome these issues. But in practice, SPV modules are interconnected and formed as SPV arrays and these are used for SPV generation in large scale applications. So these arrays are facing the PSC which results in multiple peaks in the P-V curves. This paper investigates the behaviour of three different structures of SPV arrays which gives rise to multiple peaks due to PSC. In this paper, SunPower SPR-X20- 250W-BLK module data is used to form SPV array and it is examined under PSC conditions with different irradiance (G) and temperatures (T) values. The electrical performance characteristics under PSC with three different structures of SPV array is obtained using Matlab/Simulink and are examined to get a clear idea to choose which style of connection is better for PSC.
