winget install --id PVsyst.PVsystAbout PVsyst
PVsyst is a PC software package for the study, sizing and data analysis of complete PV systems. It deals with grid-connected, stand-alone, pumping and DC-grid (public transportation) PV systems, and includes extensive weather data and PV systems components databases, as well as general solar energy tools. This software is geared to the needs of architects, engineers, researchers. It is also very helpful for educational training. PVsyst focuses on complete and precise PV system study with a complete set of tools.
What's new in 8.1.4
** New features - Weather data, known format import: integration of ANE-NEDO web API weather data for Japan. ** Improvements - P50-P90 estimation: the default annual GHI variability model was updated to a linear model based on a larger measurement dataset. ** Corrections - 3D scene: orientation averaging during 3D import now uses a geometrically correct method that properly handles fields with varying tilt, azimuth, and terrain slope - Batch mode: the batch simulations now work also for sub-hourly simulation steps (already fixed in version 8.1.1) - Power Factor: fixed issue with reactive and apparent energy values when grid limitation losses are accounted for separately and EGrdLim is not saved - Power Factor: fixed issue with apparent energy accumulation for monthly power factors, it is now correctly recognized as the norm of the vector (E_Grid, E_ReGrid) - Results: fixed issue with generating user-defined plots - Results: after viewing the tables with hourly averages, there is no more error in the irradiance balance check - System: increase/decrease arrows for the number of inverters and MPPT inputs now correctly update the values - System: fixed an issue where the inverter nominal power distribution to individual MPPT was not always correct with shared inverters - Weather data, custom file: importing custom weather data now computes global irradiance when missing from the source data.
