2 Product Overview
2.1 Product Description
Sunny Design is a software for planning and designing PV systems with and without self-consumption option, off-grid
systems, PV hybrid systems as well as energy systems. Sunny Design provides you with design recommendations for
your planned systems. Sunny Design 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 cables,
evaluating efficiency and, in case of PV hybrid and off-grid systems, configuring gensets

Sunny Design Pro:
Additional access authorization required
You require an additional access authorization for Sunny Design Pro to be able to design an energy system and
to use the advanced settings. You get information by clicking on the button [Energy systems] on the
Sunny Design home page or on your personal home page after login
