  • Average, daily nominal PV system power: 18 kWh
  • Self-consumption rate: 30% (5.4 kWh/day)
  • Electricity rate for purchased electricity: €0.295/kWh
  • Feed-in tariff: €0.118/kWh (as of October 2018)
  • Detecting increased electricity costs: 30 days

* The inverter will not start up due to a disturbance on the first day of the billing period. The increased electricity bill alerts the PV system owner to the disturbance only after 30 days.
** The installer must drive to the PV system to identify the cause of the disturbance. The PV system can be repaired only during the second visit with the replacement device procured in the meantime.

The example shown here is for illustrative purposes only and it is based on the assumptions outlined. Changes to these assumptions would change the projected outcome.
