Predicted annual yield (kWh)
The predicted annual yield of a system is calculated from the specific annual yield (kWh/kWp) at the
system location and the system power in kWp (also known as nominal power).
You can obtain the specific annual yield for the location of your PV system from irradiation maps.
Specific annual yield (kWh/kWp) x nominal power (kWp) = predicted annual yield (kWh)
PV array
Technical device for the conversion of solar energy into electrical energy. All series (= in series) and
parallel installed and connected PV modules of a PV system are referred to as a PV array.
For PV systems with micro inverters, a PV array consists of one PV module, as only one PV module can
be connected to a micro inverter.
PV array power
The PV array power is the maximum power of the PV modules connected to one inverter.
PV module
Electrical circuitry of several PV cells encapsulated in an enclosure to protect the sensitive cells from
mechanical stress and environmental influences.
PV System Setup Assistant
The PV System Setup Assistant is an application in Sunny Portal that helps you register your system in
Sunny Portal.

SMA Connection Assist
SMA Connection Assist helps you configure the devices for your network if they do not automatically
integrate into your network and connect to Sunny Portal.
Specific annual yield (kWh/kWp)
The specific annual yield is a calculated average value of specific system yield values of different
PV systems for a particular location. You can obtain the specific annual yield for the location of your
PV system from irradiation maps. You can assess the efficiency of your PV system by comparing the
specific system yield of your PV system with the specific annual yield for the PV system location.
Example: Calculation of the predicted annual yield
The specific annual yield at a PV system location is approximately 900 kWh/kWp. The nominal
power of the PV system is 4.8 kWp.
Predicted annual yield = 900 kWh/kWp x 4.8 kWp = 4,320 kWh
