2Sunny Design
2.1 Intended Use
Sunny Design is a software for planning and designing PV plants. Sunny Design offers
recommendations on possible designs for your PV plant. Sunny Design also suggests a combination
of PV array(s) and inverter(s) that are the closest to your requirements for your planned PV plant,
especially in regard to performance class and energy yield.
You can also let the program estimate your potential self-consumption of the energy generated by the
PV plant and show it in a chart.
2.2 Functions
The most important Sunny Design functions are:
• Plan projects in compliance with all legal and industrial requirements. Try different layouts and
choose from all SMA inverters.
– Simple PV plants, e.g. with one or multiple PV arrays that are arranged in the same way
– Complex PV plants, e.g. with multiple PV arrays that are arranged differently
– PV plants with three-phase feed-in and a user-defined unbalanced load limit
– PV plants taking country-specific requirements into account, e.g. inverter types or line voltage
• Create project documentation with standard values for projects
• Detect potential self-consumption of PV energy and show it in a chart
• Create own site with help from meteorological data from the Sunny Design database or
imported meteorological data
• Create own PV modules
• Automatically check operation data of the planned PV plant
• Cable dimensioning
• Print project documentation or save as PDF document
• Implement online updates for updating the Sunny Design databases and Sunny Design user
