PVsyst 7.4 is out now !

New features, improvements and many corrections

Electrical Shading Model Improvements:

· General improvement of the simplified electrical shading loss models (partitions and unlimited orientations);

· More detailed treatment of the effect of shades on the bottom row of PV cells (partitions model only);

These improvements may lead to changes in the electrical shading losses and simulation results.

New features:

· Meteo import: Possibility to import 3E TMY hourly data in import in known format;

· Optimizers : Implemented Sungrow optimizers, with sizing constraints and update of the help

· Trackers: Wind stow position for tilted axis and horizontal E-W trackers.

Shading Scene Improvements and Corrections:

· Modules are now displayed in the field edition window even if the sizing is defined "by sensitive area";

· Importing PVC files with PV tables having a tilt of 90° now works properly;

· Compound objects of type "building" type can now be transformed into ground objects;

· Module spacing set in PVC files is now taken into account when imported into PVsyst.

Databases Improvements:

· Significant updates of pumps, controllers, batteries, PV modules, inverters and Optimizers (SolarEdge);

· NREL NSRDB TMY import is now available for Asia, Australia and Pacific.

 

Corrections:

· Module layout: during simulation, securing the calculation of electrical shadings when the PV module submodules layout is not defined;

· Trackers: processing of the central gap, which is editable from the tracker's window, is now secure;

· Bifacial: loss diagram in detailed results is now coherent with the one in the report

 

· Backtracking:

o When importing a new scene, the automatic backtracking parameters are now adapted accordingly;

o Backtracking table width is not overestimated by adding the inactive frames anymore;

o Frames are now handled correctly for north-south and tilted axis trackers.

 

· Components:

o The reordering of points in the "Measured low-light data" sub tab no longer causes crashes

o Battery: Several small interface errors, like the edition of the number of cycles, have been resolved

 

· Economic evaluation:

o Displayed energy production is now correct

o Quantity for batteries in investment costs is now correct when using Universal Batteries

 

· Report:

o Inactive band values are now consistent with orientation and 3D scene

o The report is now refreshed when changing details of client or author in the options

o The vertical scrollbar of hourly graphs now works properly for leap years

 

· 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
