Chart
The chart shows:
-
Dotted lines: Forecasted power in kW for a 7-day horizon (here: 6-13 November).
-
For comparison, you can see the actual power in kW (red line) and POA irradiance (yellow line), in this case for 3-5 November.

View historic values
To view historic forecast values, you can create a user-defined chart. This allows you, for example, to evaluate the deviation between the VCOM forecast, actual power values, and other parameters.
Prerequisites
-
VCOM forecast has been activated in VCOM for the relevant system(s).
-
“Create” permission for the Evaluation module. See User group modules and permissions.
Steps
-
Create a term using the abbreviation FORECAST_POWER. See Terms.
-
The forecast term you created should now be visible in the user-defined charts in the category Sensoric/Calculated.
-
Create a user-defined chart with the desired values, e.g. actual active power and sensor irradiance values. See Create and save user-defined charts with the chart generator.
Your chart containing historic data is now displayed in the Evaluation area of VCOM.
