Exemplary loss breakdown chart displaying data of a system with Over-performance in Month view, also including the Yield forecast — Exemplary loss breakdown chart displaying data of a system with **Over-performance** in **Month** view, therefore also including the **Yield forecast** and its difference value

Basic info

Description	The chart breaks down the deviations between a system’s forecasted, expected, and actual energy generation. Therefore, it displays the following values for the selected system: Forecasted energy from the Yield forecast (only as of Month view) and its difference to the expected energy that is simulated without considering curtailments, displayed as Difference yield forecast/simulation both displayed only as of Month view Expected energy that is simulated without considering curtailments, displayed as Simulation without considering active power curtailments and its difference to the expected energy simulated with curtailments, displayed as expected Power control losses. These are not the actual power control losses, but only the ones calculated with the selected simulation method. Expected energy simulated considering active power curtailments, displayed as Expected energy (simulation) and its difference to the actual energy generation, displayed either as Actual Over-performance or Actual Losses Actual energy (= Yield)
Prerequisites	Simulation method for the expected power/energy is configured. See also Configure the simulation.
Further details	Expected power control losses are only displayed if an active power curtailment is considered in the calculation within the selected period. Actual losses consist of: Negative deviations outside of the target range of the expected energy with curtailments Losses due to technical issues specified in tickets Losses due to data/communication gaps (loss extent calculated on satellite data) Forecasted values are only visible if a yield forecast is configured, see Configure yield forecast.

Description

The chart breaks down the deviations between a system’s forecasted, expected, and actual energy generation. Therefore, it displays the following values for the selected system:

Forecasted energy from the Yield forecast (only as of Month view)
- and its difference to the expected energy that is simulated without considering curtailments, displayed as Difference yield forecast/simulation
- both displayed only as of Month view
Expected energy that is simulated without considering curtailments, displayed as Simulation without considering active power curtailments
- and its difference to the expected energy simulated with curtailments, displayed as expected Power control losses. These are not the actual power control losses, but only the ones calculated with the selected simulation method.
Expected energy simulated considering active power curtailments, displayed as Expected energy (simulation)
- and its difference to the actual energy generation, displayed either as
  - Actual Over-performance or
  - Actual Losses
Actual energy (= Yield)

Prerequisites

Simulation method for the expected power/energy is configured. See also Configure the simulation.

Further details

Expected power control losses are only displayed if an active power curtailment is considered in the calculation within the selected period.
Actual losses consist of:
- Negative deviations outside of the target range of the expected energy with curtailments
- Losses due to technical issues specified in tickets
- Losses due to data/communication gaps (loss extent calculated on satellite data)
Forecasted values are only visible if a yield forecast is configured, see Configure yield forecast.
