8.3.3 Entering the Predicted Annual Yield
The predicted annual yield is the yield to be expected from a PV plant within one year. Sunny Portal
uses a table to show how the predicted annual yield of your PV plant is distributed throughout the
months of the year.
The predicted annual yield of the PV plant is calculated from the specific annual yield (kWh/kWp) at
the location of the PV plant multiplied by the plant power in kWp. The plant power is also called
nominal power.
You can obtain the specific annual yield for your PV plant location from irradiation maps. Local
conditions such as degrees of shading or the orientation of the plant are not taken into account.
You can find out the plant power in kWp from your installer.
1. Select "Configuration > Plant Properties".
2. Select the "Parameters" tab.
3. Select [Edit].
4. Enter specific annual yield in kWh/kWp in the "Specific Annual Yield" field.
5. If the "Plant Power (Nominal Power)" field is empty, set the plant power (see Section 8.1.4
”Setting the Plant Power” (page 50)).
6. Select [Save].
Changing the monthly distribution of the predicted annual yield
The monthly distribution shows how the predicted annual yield is distributed throughout the months of
the year. Given full details of the plant location, Sunny Portal can suggest a distribution. You can also
enter the distribution manually.
1. Select "Configuration > Plant Properties".
2. Select the "Parameters" tab.
3. Select [Edit].
4. If the "Plant Location" field is empty, enter details of the plant location under the "Plant Data" tab
(see Section 8.1.1 ”Changing General Plant Data” (page 49)).
5. Select [Suggest a Monthly Distribution].
6. In order to enter the monthly distribution manually, enter values in the "in %" fields.
7. Select [Save].
