Abstract |
|
|
| We present the comparison of the solar PV array efficiency using four different methods such as Total Cross Tied (TCT), Minimum Distance Average (MDA), Index Squaring Method (ISM) and Calcudoku method (CM). TCT and MDA are considered as conventional method and each method is discussed for the four different cases such as Short Narrow (SN), Short Wide (SW), Long Narrow (LN), and Long Wide (LW) respectively. The PV array is configured using the ISM in which they are arranged according to their impact of shading approach for various irradiances. CM uses a mathematical puzzle- based approach for PV array reconfiguration to improve their array currents. The proposed techniques for reconfiguration of PV arrays can improve PV power under different partial shading conditions. The performance of PV arrays for the mentioned methods are discussed and analyzed. The efficiency of the PV panels are compared using the Monte Carlo technique for various irradiance values and the results of the comparisons are presented to show the best suited techniques with respect to their power enhancement. |
