Updates February 2021

Equipment and site details, Chinese cable sizing standard, energy simulation charts

pvDesign - backend v4.8.80, frontend v1.0.7

New Features

In February 2021 we released many new features in the web app and additionally we included a new cable sizing standard.

  • Equipment details: It is now possible to review the detailed information of photovoltaic modules, inverters, and mounting structures. The information is available in the design process page, and in the equipment page as well.

  • Chinese cable sizing standard: Users can now choose to size the cables in the PV plant according to the Chinese national standard (GB 50217 - 2018).

  • Sort equipment tables: The tables used for selecting PV modules and inverters can now be sorted by power and voltage.
  • Site details: There is more information available about the site itself, the meteorological resource, the horizon profile and the albedo data.

  • License expiring messages: Users will now be notified when their license status is about to change.

Bug fixes and improvements

In February we also introduced many smaller bug fixes and improvements:

  • We fixed a bug which caused the clearance distance value to be wrong in the interface.
  • We fixed a bug which caused some elevation CSV files to fail to upload
  • We made some changes to how we request meteorological data information to the PVGIS service. The results show now be more consistent.
  • We fixed some issues which were affecting the users who logged in using federated logging.
  • We increased the maximum power value for string inverters to 350 kW AC, to allow our users to upload some recent inverters exceeding the old limit of 300 kW AC.
  • We improved the database structure used to store information about projects. Now the homepage of pvDesign should load significantly faster than before.
  • We increased the maximum value for the distance to perimeter input to 25m.
  • We increased the maximum number of restricted areas per site to 75 areas.
