Release Notes 6.40 - 6.49

 

In version 6.49 (30.09.2016)

PVsyst now uses hardware acceleration and requires display drivers which support OpenGL 2.0. Please make sure they are up-to-date.

  2. ModuleLayout: Modules not displayed correctly in southern hemisphere
  3. Batch mode: crash with ModuleLayout
  4. Errors in 3D objects manipulation (double-click on Gizmo)
  5. Read PV modules: IAM customized profile not read in the database
  6. Stand-alone systems: Controller voltage thresholds incorrect when several batteries in parallel
  7. In some special cases (modif. parameters after simulation): on the report, simulation may be not coherent with the input parameters
  8. SolarGIS files reading: crash when the Timezone is not an integer (India)
  9. P50-P90 dialog: value out of limits at dialog opening

In version 6.48 (13.09.2016)

Novelties:

We are in a phase of stabilization and internal modernization of the software, after the deep changes in the version 6.40 and followings.
Every PVsyst user is encouraged to communicate any problems encountered when using the program.
Important novelties are in preparation, but not yet published.

Improvements:
  1. Backtracking parameters info in the “Orientation” part
  2. Database update
Fixed errors:
  1. Blocking error when developing a tracking system in the version 6.45.

In version 6.43 (18.03.2016)

This version doesn’t provide much novelties.
We are in a phase of stabilization and internal modernization of the software, after the deep changes in the version 6.40 and followings.

  4. Reading error when defining zones in the 3D shadings.

In version 6.40 (18.01.2016)

*** This should be considered as a major version ****

Novelties:
  1. Battery system management has been deeply reviewed and partially rewritten.
    The system dialog is now much more comprehensive
    Battery charging Control may be specified in terms of SOC (not battery voltage)
    Visual tool for the relationship between SOC and Voltage thresholds as function of the battery temperature, charging/discharging currents, etc.
    The Presizing tool has been improved (works on several years)
    New tool for an overview of the sizing issues (parametric diagrams)
    Battery simulation treats all kinds of losses as defined for the Grid systems.
    User’s needs management deeply modernized.(namely domestic uses with time of use for each appliance)
  2. 3D Shading tool management:
    New algorithm for the shading factor calculation.
    => Calculation time drastically reduced (by factor of 20)
    Import a ground image (google, architect plan, etc) as “background template” for the development of the scene.
    Drawing of objects with the mouse, directly in the scene (useful namely with ground image)
    Smart tool for the displacement of objects
    New objects: domes (opposite sheds), Wind turbines, etc
    The shading effect may be desabled for chosen objects.
    Inversely, the ground objects may be specified as throwing shades
    The Shading factor calculation for a partial sub-system has been improved.
  3. System (sheds) optimization tool:
    Reworked the dialog, with a viewer integrated into a single window,
    Generic parameter selection
    Sketches to visualize selection range and the calculation progression
    Scans of Tilt and Azimuth are now possible for all types of orientations (except tracking).
    The Help has been developed.
  4. All the data files written as Text files.
    This implies a new Workspace kind named  PVsyst640_Data.
    Older versions of PVsyst cannot access this new workspace.
Improvements:
  1. Meteo data import: the dialog has been reviewed, new faciliting features
    Improvement of the Help, enrichment concerning all data sources.
    Direct Import for new Meteo data providers:
    – NREL for the Indian territory (satellite data in 10×10 km),
    – Vortex (private  company, for pay).
  2. The dialog for the management of projects has been modernized
    The project may/should be explicitely saved after each modification
    Number of Calculation variants now illimited  (VCi, VDi, etc).
  3. License validation: modified for keeping the license when updating to Win10.
  4. PVsyst can be started from a script.
Fixed errors:
  1. Blocking error when developing a tracking system in the version 6.45.
  2. Backtracking: error in diffuse shading factor calculation (only in V 6.45).
  1. Numerous errors fixed thanks to the Error reporting tool which allows to send
    deteiled reports of your errors to our support team.
  2. Use with Windows XP difficult due to lack of Microsoft maintenance:
    Namely Meteonorm 7.1 requires .NET 4.5, not suported by Win XP.
    => Syntheric generation (normally managed by Meteonorm) has to switch
    to the old generation
