kjs55 Posted September 8, 2022 Share Posted September 8, 2022 (edited) It is reported in literature  that the p50 (median) derived from a Monte Carlo- or convolution-based uncertainty analysis  is more appropriate to use (and not always the same) as the primary AC energy into grid value (E_Grid simul) that comes out of PVsyst. e.g., Not all the distributions that feed into the Monte Carlo are normal Gaussian distributions (e.g., the Gamma-shaped degradation rate distribution from Dirk Jordan -). Does the p50 in the PVsyst p50 estimation directly use E_Grid simul? Or is the p50 derived from the uncertainty analysis? Is it really a median p50 (or is it simply E_Grid simul)?  https://www.researchgate.net/publication/318259323_A_Framework_to_Calculate_Uncertainties_for_Lifetime_Energy_Yield_Predictions_of_PV_Systems/  https://www.eupvsec-proceedings.com/proceedings?paper=19917/  https://onlinelibrary.wiley.com/doi/10.1002/pip.3566/ Edited September 8, 2022 by kjs55 Add convolution option (requires significantly less computational work) Link to comment Share on other sites More sharing options...
