Loss breakdown chart

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

• Forecasted energy generation from the Yield forecast

  • and its difference to the expected energy generation that is simulated without considering curtailments, displayed as Difference yield forecast/simulation

  • both displayed only as of Month view

• Expected energy generation 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 generation 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 Yield

• Configure Simulation: Determine a Method and Target range for the expected, simulated energy. See also Simulation.

• Values for the expected energy depend on your selection of the simulation method.

• 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.
