With the addition of a 12kWp solar photovoltaic array, the Good Energy Haus is now a certified Passive House Plus. It was already climate-neutral with its extremely low energy consumption and 100% wind-power electricity supply. The on-roof PV system delivers lower electricity cost than the grid-tied supply. It is therefore a testament to the fact that doing the right thing also saves money.
