During planning for their new building in 2009, the Butterweck-Werner family in Kassel, Germany, were certain that they needed a PV system. This is because living sustainably and minimizing their impact on the environment and the climate represents an approach to life for the Butterweck-Werner family – one that they also want to pass on to their son. The goal for the family of three is to use as much of the self-generated solar power as possible directly at home and to make big savings on energy costs.
Electricity from the roof for the washing machine, dishwasher, etc.
In the new house, the electricity supply has gone green and is self-generated. The 13.455 kWp PV system generates around 11,033 kWh of solar power per year and supplies electricity for the washing machine and dishwasher from their own roof. Self-generated green power is also used to provide warm water and energy for heating.
