Ist der PV-Rechner wirklich kostenlos?

Ja, der PV-Rechner mit 3D-Dachplaner ist vollständig kostenlos und ohne Anmeldung nutzbar. Sie können Ihre PV-Anlage planen, den Ertrag berechnen und die Wirtschaftlichkeit simulieren – inklusive Batteriespeicher und 25-Jahres-Prognose.

Welche Daten werden für die Ertragsberechnung verwendet?

Die Berechnung basiert auf realen Wetterdaten des Deutschen Wetterdienstes (DWD). Für Ihre PLZ wird die nächstgelegene DWD-Station mit stundengenauen Globalstrahlungsdaten verwendet – für eine realistische Ertragsprognose.

Kann ich mit dem Tool auch Angebote von Solateuren einholen?

Ja. Nach der Planung können Sie Ihre Konfiguration speichern und direkt Angebote von Solateuren in Ihrer Nähe einholen. Die Solateure erhalten Ihre Dachplanung, Modulbelegung und Verbrauchsdaten als Grundlage für ein präzises Angebot.

Most manufacturers guarantee 70-80% capacity after 10 years

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

Includes degradation of 0.5% per year

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.
