12.12 Entering the Amount of CO2 Avoided
The CO
2
factor indicates how much CO
2
is produced during the power generation of one kilowatt
hour. The CO
2
factor can vary depending on the grid operator. To find out the level of the CO
2
factor for one kilowatt hour of electric current, contact your grid operator.
SunnyPortal can use the CO
2
factor to calculate how much CO
2
was saved due to the power
generation of your system.
You can view the value of CO
2
avoided on the following pages:
• PV system profile page
• Daily info report or Monthly info report (see Section11.3.2, page102).
Requirement:
☐ You must have the user role Installer or PV System Administrator (see Section13.1,

12.13 Automatic Calculation of the Predicted Annual Yield
SunnyPortal can display in a table how the predicted annual yield of your system is likely to be
distributed throughout the months of the year.
The predicted annual yield of the system is calculated from the specific annual yield (kWh/kWp) at
the system location multiplied by the nominal PV system power.
You can obtain the specific annual yield for your system location from irradiation maps. Local
conditions such as the shading or orientation of the system are not taken into account by
SunnyPortal.
