Plant design made easy

With the latest release of the Sunny Design application, designing PV systems is even easier. Simply install Sunny Design on a Windows-operated PC or open the online version using a browser, iPad or Android tablet, enter all required data and receive the ideal plant configuration within minutes. The application provides solar power professionals and system planners with a user-friendly interface, which thanks to the new desktop version matches Sunny Design Web. The software also delivers data for an economic evaluation of the system alongside the technical verification of the various components. The end customer gains a customized PV plant and the solar power professional saves valuable time.

Release Notes Sunny Design 3.10 (Desktop Version)

  • In Sunny Design there are now three different project types available which are individually tailored to specific requirements: PV system without self-consumption, PV system with self-consumption, and PV hybrid system. These projects are identified in the overviews by corresponding symbols.
  • In the project data it is now possible to enter active power limitation specifications manually within a wide setting range.
  • In projects with self-consumption, the Sunny Home Manager can be used to limit active power, e.g., for implementation of the 70% cap in accordance with the Renewable Energy Sources Act (EEG). This is also taken into account in the yield forecast.
  • Also for projects with self-consumption, a new planning stage has been introduced under the heading "Define load profile". This provides not only a chart of average daily profiles, but also an editor for creating individual load profiles.
  • The design now takes into account the requirements of country-specific standards in Belgium (RGIE), Australia (AS/NZS 5033) and Italy (CEI-021).
  • The new section "Planning of PV system monitoring" provides the possibility of integrating communication products (hardware and software) for system monitoring, system management and visualization of key system data in the PV system. This new function also offers design options based on the specific requirements for PV system monitoring.
  • The sizing of AC cabling now also supports split-phase grids.
  • Project documentation for design alternatives can now be created quickly and easily.
  • The dialog for creating your own PV modules has been optimized. All mandatory specifications have been condensed in one list to facilitate their entry.
  • Missing PV module data can now be transmitted by e-mail via a link on the homepage.
  • The user interface and the documentation are now also available in Japanese.
  • The new version has been prepared for inverters with integrated battery. Their properties will in future be taken into account for design, yield simulation and self-consumption forecasting.
