2 Product Overview SMA Solar Technology AG User Manual 7 SD3-SDW-BA-en-21 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.
