7 SMA Solar Technology AG 2 Product Overview 2 Product Overview 2.1 Product Description Sunny Design is a software for planning and designing PV systems with and without self-consumption, off-grid systems, PV hybrid systems as well as energy systems. Sunny Design provides you with a design recommendation for your planned system or your planned energy system. Sunny Design also proposes a combination of PV array(s) and inverter(s) which meet, as closely as possible, your requirements regarding power class, energy yield and efficiency. In addition, you have the option of determining and optimizing your potential self-consumption, sizing the cables, evaluating efficiency and, in PV hybrid systems and off-grid system, configuring gensets. Difference Between Sunny Design Web and Sunny Design Desktop Version Sunny Design is available as an online version "Sunny Design Web" and as a desktop version "Sunny Design 3". You must install the Sunny Design desktop version on your computer. To use the Sunny Design desktop version, you must first register for Sunny Design Web. After the initial registration, you do not need an Internet connection. To ensure that your Sunny Design desktop version remains current, (e.g. new inverters, new PV modules), you should occasionally perform an update for the Sunny Design desktop version via the Internet (see Section 5.4, page 22). The Sunny Design desktop version can only be used by one user per computer. After initial login to the Sunny Design desktop version on the computer, the Sunny Design desktop version can only be used by this user on this computer. You can only use Sunny Design Web via the Internet. You can synchronize Sunny Design Web and the Sunny Design desktop version via the Internet. This means that your Sunny Design projects are available in the Internet in Sunny Design Web and on your computer in the Sunny Design desktop version. For synchronization, you must have an Internet connection and the latest software version of the Sunny Design desktop version (see Section 5.5, page 22). Sunny Design Pro: An additional access authorization is required for designing an energy system and for advanced settings. You require an access authorization for Sunny Design Pro to be able to design an energy system and to use the advanced settings. You will receive the information via the button [Energy systems] on the Sunny Design Web home page or on the personal start page after login.
