In non-uniform conditions, the power curve of a solar plant can vary significantly, which can affect the performance of the system. In such conditions, the configuration of the panels can help reduce the mismatch losses. Although dedicated electronics may be helpful in reducing a panel's mismatch, the panel configuration is a recent solution that can also reduce a panel's overall power consumption and mismatch losses. Hence in this paper Sider Web Tie (S-B-T) PV panel configuration is proposed. A test case of 5 X 5 200 W PV panel is considered. The proposed S-B-T PV configuration is implemented under real time PSC's in comparison with Series-Parallel (S-P), Total Cross-Tied (T-C-T), Triple-Tied (T-T), Bridge-Link (B-L) configurations. The factors such as PV mismatch losses, Max. current and voltage, OC Voltage, SC Current that influence the performance of the system are investigated. In all the cases proposed Spider Web Tie (S-B-T) PV configuration exhibits the superior performance.

One of the major concerns for continuous solar photovoltaic (PV) generation is partial shading. The movement of clouds, shadow of buildings, trees, birds, litter and dust, etc., can lead to partial shadow conditions (PSCs). The PSCs have caused inconsistent power losses in the PV modules. This leads to a shortage of electricity production and the presence in the PV curve of several peaks. One of the simplest solutions to PSC’s is the PV configurations. The objective of this paper is modelling and simulation of solar PV system in various shading scenarios for KC200GT 200 W, 5 x 5 configurations that includes Series/Parallel (SP), Total-Cross-Tied (TCT), Triple-Tied (TT), Bridge-Link (BL) configurations. Real time PSC’s such as corner, center, frame, random, diagonal, right side end shading conditions are evaluated under all PV array configurations. A comparative analysis is carried out for the parameters such as open circuit voltage, short circuit current, maximum power point, panel mismatch losses, fill factor, efficiency under all PV configurations considering PSC’s. From the comparison analysis best configuration will be presented.
