Performance Amplification Of PV System Configurations Under Partial Shading Conditions Employing Magic Square Technique

Abstract

Nonrenewable sources of energy are inadequate to satisfy the electricity requirement with the rapid development of industries and other areas. Also, high consumption of these sources is inversely related to its life expectancy. Thus, non-conventional sources of energy play an essential part in generating electricity. Among all non-conventional resources, solar power is significant as it is clean energy source, easily and freely available, requires lesser maintenance, ecofriendly and economical. The Photovoltaic (PV) cells are widely used all over the world to convert energy of sun into electricity. The functioning of system is concerned by elements like irradiation, temperature rise, array topologies and shading effects on panels. newlineThe intent of my work is inspecting and amplify yield of operating solar systems. Two of the major concerns in solar array due to partial shading are: Increase in Mismatch Losses (ML) and decrease in efficiency. The complete PV array system is concerned negatively with regard to efficiency by a little measure of shading on the PV module. The shading is the consequence of moving clouds, high rise buildings, long trees, shadow of one panel onto another etc. Due to this partial shading, many challenges occur in enhancing the performance of the PV solar array. The challenges include deviation of Maximum Power Point (MPP), power losses resulting in hot spot formation, degradation in power quality etc. newline newline
