Comparison of solar PV array configuration methods under different shading patterns

Abstract

Power generation of solar photo voltaic array (SPVA) reduces than the standard rating of the photovoltaic panel under shading condition. Since the SPVA's modules receive different solar irradiations, it leads to multiple peaks on P-V characteristic of SPVA. Considering the cost involved of PV system, procedures are created to improve the power age of PV by distributing the shading impact over whole PV array by adjusting the physical position of the modules without modifying any electrical setup of the modules in the PV cluster. An algorithm based technique, physical relocation of modules with a fixed electrical connection (PRM-FEC) is considered in this paper under various sorts of shading designs over customary setup total cross tie (TCT) for 4×4 cluster since this calculation is appropriate for exhibits where section not equivalent to push as well. It is found that PRM-FEC arrangement is not enhancing the power for all the types of shading patterns.
