linkeshd Posted December 29, 2020 Share Posted December 29, 2020 In PVsyst 7.0.8: Using the graphical tool for studying the Module Mismatch, I know there are some random seeds, but the two tools ("Show histogram" and "Show graph") give widely different results.Using a system comprised of JKM 315PP-72 modules, 19 units in series, 20 chains in parallel, and Normal (Gaussian) distribution, I get the following two behaviors:Using the Show histogram Tool:Pmpp loss average =2.4 %. Clicking "More statistics" increases the random sample pool, but tends to converge around a value similar to initial value (in my case, it jumped to 2.8% then converged down to 2.4% as I increased the sample size).This is reasonable and expected behavior of a randomized normal calculation.Using the Show graph tool:Each calculation gives wildly different results, ranging from 1.5% to 4.5%, and jumping widely with each recalculation.This is counter-intuitive and dissimilar to what I experienced in PVsyst 6.8.8 wherein the value shown in the graph was relatively constant.Please check?Thank you!
