Enhanced Solar PV Power Generation Under PSCs Using Shade Dispersion

The solar photovoltaic (PV) array generates the power below the rated value due to the shading intensity and shading pattern losses under partial shading conditions (PSCs). The different levels of solar irradiance are received by the modules of PV array under PSCs; it causes the mismatch between the generated module currents, leading unfortunate impacts such as hot-spot and therefore total PV power generation reduces. Resulting, the efficiency of solar PV array decreases. This article presents the optimal energy harvesting using physical relocation and fixed column position of modules with fixed electrical connection (PRFCPM-FEC) under different shading conditions. The proposed algorithm is presented for m x n modules under different shading conditions. The locations of modules are changed according to the proposed configuration without removing the electrical connections. A comparative analysis has also been presented between proposed pattern configuration, total cross tied (TCT), and physical relocation of the modules with a fixed electrical connection (PRM-FEC) configurations. The results demonstrated that the proposed array configuration produced the improved performance under PSCs.
