Plant Power in kWp
The plant power in kWp (kilowatt peak) is the maximum possible plant power. The plant power in
kWp is also known as the nominal power of the plant.
The peak power of a PV plant is the sum of the peak powers of all PV modules installed (see peak
power of a PV module). The peak power of a PV plant is used to compare the plant yield and plant
costs with other PV plants, for example. The peak power of a PV plant is often referred to as "plant
power (kWp)".
An installed plant can rarely achieve peak power because it is not installed in laboratory conditions.
Plant Setup Assistant
The Plant Setup Assistant is an application in Sunny Portal that helps you register your plant in
Sunny Portal.
Predicted Annual Yield (kWh)
The predicted annual yield of a plant is calculated using the specific annual yield (kWh/kWp) at the
plant location and the plant power in kWp (also known as nominal power).
You can obtain the specific annual yield for your PV plant location 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 electrically connected
PV modules installed in series or in parallel within a plant are referred to as a PV array.
For plants 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 that are connected to one inverter.
PV Module
Electrical connection of several PV cells encapsulated in an enclosure to protect the sensitive cells from
mechanical stress and environmental influences.

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.
Example calculation of the predicted annual yield
The specific annual yield at a PV plant location is approximately 900 kWh/kWp. The nominal
power of the PV plant is 4.8 kWp.
Predicted annual yield = 900 kWh/kWp x 4.8 kWp = 4,320 kWh
