“…The corresponding RMSE values are 9.86022 × 10 −4 , 7.73006 × 10 −4 , and 7.72986 × 10 −4 . These results are in good agreement with references [6,7,17,20,29,[39][40][41][42][43][44][45][46][47][48]. Furthermore, the SDM parameters (I ph , I 0 , R s , R sh , and n) attained from the PWP 201 PV module by using the approximation method, the LW method, and the NR method are (1.03051 A, 3.48226 µA, 0.03337 Ω, 27.27728 Ω, and 1.35119), (1.03143 A, 2.63808 µA, 0.03432 Ω, 22.82337 Ω, and 1.32217), and (1.03143 A, 2.63813 µA, 0.03432 Ω, 22.82332 Ω, and 1.32218), respectively.…”
