Robin Vincent Posted May 2 Posted May 2 This post aims to present the main differences a user can encounter when using PVsyst 8.0.12 compared to PVsyst 8.0.11, including PVsystCLI. New functionalities for PVsyst CLI Three new parameters have been added to the run-simulation command: --batch-params-file (-bpf) --batch-rvt-file (-brf) --recompute-shadingfactors-tables (-rst) The two first will allow running a batch of simulations from CLI, thus enabling automatized parametric studies. An example use case has been added to the page https://www.pvsyst.com/help-cli/use-cases/simulation.html The third option allows choosing whether shading factor tables should be recomputed at the beginning of the simulation. More information on the commands and their usage can be found at https://www.pvsyst.com/help-cli/reference/index.html Correction impacting the modeling of optimizers Release note: Optimizers: Minor update of the optimizers MPP choice under partial shadings with module layout shading model When using the “module layout” shadings model, the MPP tracking algorithm now works better during partial shading conditions. In previous versions, it used to select an MPP at low voltage output, sometimes leading to inverter minimum voltage related losses. This correction may lead to a slight production increase, mostly from a reduction of inverter voltage threshold losses. Other minor corrections in the context of the modeling of optimizers concern Huawei optimizers : Correction of the efficiency computation, leading to a slight increase of the optimizer efficiency losses. With long strings (i.e., when the string voltage at STC is higher than the inverter MPP input maximum voltage), the individual optimizers' operating point selection now takes into account the minimum inverter input voltage. Under low-light conditions, this may improve the inverter efficiency by selecting a higher voltage operating point. Updated Bifacial PR The bifacial PR is now available in the report and in the monthly result tables. Its abbreviation is “PRBifi”. Note that the definition was also updated to now take into account the bifaciality factor.
