Wie effektiv arbeitet unsere PV-Anlage wirklich?

Um herauszufinden, wie effektiv eine PV-Anlage tatsächlich arbeitet, gibt es eine einfache Lösung: Die Berechnung der Performance Ratio. Sie steht für das Verhältnis von tatsächlichem Energieertrag Ist-Wert der PV-Anlage zum theoretisch möglichen Energieertrag Soll-Wert.

Leistungsfähige PV-Anlagen erreichen eine Performance Ratio von über 70%.
Die Performance Ratio wird oft auch als Qualitätsfaktor bezeichnet. Solarmodule auf der Basis von kristallinen Zellen erreichen einen Qualitätsfaktor von 0,85 bis 0,95.

Netzgekoppelte Anlagen liegen im Durchschnitt bei 70 bis 75 %.
