New features:

- Meteo import: possibility to import 3E TMY hourly data in Import in known format
- Optimizer: implemented Sungrow optimizers, with sizing constraints (inverters allowed, limits on the number in series, etc.) and update of the help
- Trackers: wind stow position for tilted axis and horizontal North-South trackers.

Improvements:

- Databases: significant updates of pumps, controllers, batteries, PV modules, inverters and optimizers (SolarEdge)
- Electrical shadings, partitions model and unlimited orientations: improvement of the model. This improvement may lead to changes in the electrical shading losses and simulation results
- Electrical shadings, partitions model: more detailed treatment of the effect of shades on the bottom row of PV cells. Simulation results from the calculation in partitions, or "according to strings", may change. The help pages have been updated accordingly
- Meteo: NREL NSRDB TMY import is now available for Asia, Australia and Pacific
- Shadings: modules are now displayed in the field edition dialog even if the sizing is defined "By sensitive area"
- Simulation: batch mode now handles the use of column separators in text fields of parameter files
- Simulation: in the batch mode it is now possible to avoid overwriting existing parameter files
- Spectral correction: improved messages to user, if spectral correction model cannot be applied.

Corrections:

- Backtracking: when importing a new scene, the automatic backtracking parameters are now adapted accordingly
- Backtracking: backtracking table width is not overestimated by adding the inactive frames anymore
- Backtracking: frames are now handled correctly for north-south and tilted axis trackers
- Bifacial systems: loss diagram in detailed result is now coherent with the one in the report
- Economic evaluation: displayed energy production is now correct
- Economic evaluation: quantity for batteries in investment costs is now correct when using Universal Batteries
- Losses: the loss diagram is now displayed correctly for systems with storage and weak grid islanding
- Module layout: during simulation, securing the calculation of electrical shadings when the PV module submodules layout is not defined
- PV components: the reordering of points in the "Measured low-light data" sub tab no longer causes crashes
- PV components, battery definition dialog: several little dialog errors, like the edition of the number of cycles, have been resolved
- Report: inactive band values are now consistent with orientation and 3D scene
- Report: the report is now refreshed when changing details of client or author in the options
- Results: the vertical scrollbar of hourly graphs now works properly for leap years
- Shadings: importing PVC files with PV tables having a tilt of 90° now works properly
- Shadings: compound objects of "building" type can now be transformed into ground objects
- Shadings: PVsyst doesn't crash anymore when loading a project containing a ground image with wrong file format
- Shadings: module spacing set in PVC files is now taken into account when imported into PVsyst
- Shadings: modules in polygonal fields are now correctly displayed
- Shadings: importing very large H2P files doesn't crash PVsyst anymore
- Shadings: PVsyst doesn't crash anymore and displays an error message when trying to import a ground data CSV file with the wrong format
- Simulation, batch mode: when using bifacial trackers all geometrical parameters are again accessible
- System: in the bifacial window, when using tracker systems, the sun position at sunrise and the plots 'beam on ground' and 'global on ground' have been corrected
- System: PVsyst doesn't crash anymore when accessing "power sharing" with an empty subarray
- Trackers: processing of the central gap, which is editable from the tracker's dialog, is now secure
- Translation: keyboard function key now works in the project window even if it has been used in the home window
- Workspace: importing variants with empty subarray list doesn't crash anymore.
