• Power consumption of a house: 11500 kwh

    Orientation of the solar panels: southwards+ a solar panel on the garden which is called smartflower

    So we need a garden.

    technical sheet of smartflower:

    production: between 3400 and 6200kwh

    but between 50 and 63 km/h of wind it folds up

    price: 23000 Euros


    wind mills: it’s very expensive and not profitable.

    Heat pump:We have looked for a heat pump to reduce the house consumption and it costs between 8 000 and 14 000 Euros.
