** New features
- 3D scene: .pvc2 and .pvz2 file formats are now supported for 3D data import
- Optimizers: it is now possible to set up more than 2 strings per MPPTs in compatible Huawei's inverter + optimizer combinations.
** Improvements
- Bifacial: improved the choice of ground points for the bifacial 2D view factor model. Ground irradiances and reflected view factors may change slightly, especially at large pitches
- Economic evaluation: operating costs can now be scheduled by year, year range, or specific years
- Output file: GHI clear sky and DHI clear sky are now available as variables to be exported
- System: minimum temperature from the MET file is now displayed, with a warning when it is lower than the lower temperature for absolute voltage limit defined in the project settings
- Weather data: new option to generate 5-minute and 15-minute synthetic weather files with Meteonorm. These files can be used for clipping correction but are not retrocompatible with prior PVsyst versions (*)
- Weather data, Meteonorm: update to V9.0.10
- Weather data, NSRDB: added MSG and Polar resources for API imports in Europe, Africa and regions north of 60°N
- Weather data, custom file: multi-year CSV imports now create one MET file per calendar year.
** Corrections
- 3D scene: improved tracker orientation grouping when importing a shading scene
- Bifacial: loss diagram is now correctly displayed when the bifaciality factor is set to zero
- Economic evaluation: improved condition to display prefix for big amounts
- Loss diagram: improved display of energy from grid and missing energy, with better handling of text overlaps and crossing lines
- Ohmic losses: fixed issue resetting losses to zero after simulation in certain situations
- Report: charge and discharge strategy plot content and scale have been corrected
- Results: fixed issue with grid limitation values in hourly graphs
- Simulation: unbalanced MPPT configurations with multi-orientations daily sharing now account for inverter maximum power function of cos(phi) and temperature
- Weather data import: the assistant no longer allows saving a file with critical errors
- Weather data, NSRDB: NREL references have been renamed to NLR in import windows.
