Solar PV yield
Estimate annual AC solar generation from system size, regional irradiation, and one or two roof orientations.
Open calculatorSolar PV sizing
Suggested system capacity is your annual electricity consumption multiplied by the target coverage percentage, then divided by the orientation-adjusted specific yield. Remember that adding a heat pump or electric vehicle can double a household’s annual kWh demand. The optional roof-fit check assumes roughly 225 W/m² (a 485 W module takes up ~2.2 m²).
Total yearly electricity use — include household appliances, heat pump and EV home charging.

Coverage refers to the annual kWh total — in winter you will still import electricity from the grid.
