Optimum: -- kWh
Kein Batteriespeicher empfohlen
Bei der aktuellen Anlagengröße im Verhältnis zum Stromverbrauch wird der PV-Ertrag nahezu vollständig direkt verbraucht. Ein Speicher würde sich wirtschaftlich nicht lohnen, da kaum Überschussenergie zum Zwischenspeichern vorhanden ist.
Optimum is larger than current setting

What is full feed-in?
With Full feed-in the entire generated solar power is fed into the public grid. You receive the EEG remuneration for each kWh fed in. This variant is particularly suitable if you consume little electricity during the day or receive higher remuneration than with partial feed-in.
Annual yields with full feed-in
| Year | Yield (kWh) | Cumulative (kWh) | Remuneration (€) | Op. costs (€) | Net (€) |
|---|
EEG remuneration runs for 20 years from commissioning. From year 21: Forecast with market price 0.04 €/kWh
Inverters and other components may require replacement within the 25 years – these costs are not included in the calculation.
