The Hacker Familiy – Craftsmen & Housebuilders
Being independent is of great importance for Tanja and Stephan Hacker. This can not only be seen in their self-constructed home but also in their energy supply. To supply not only the classic household consumers but also the in-house heat pump with self-produced solar energy, the couple deliberately opted for a PV system with a peak power of 30 kWp. Thanks to the solar power battery VoltStorage SMART, the Hackers take another step towards becoming more independent from the energy market—not only during the day, but also in the evening and at night.
Since March 2019, the Hacker family has been relying on VoltStorage’s ecological home battery. Together with VoltStorage, they have decided to start with a single unit. After one year, VoltStorage will use the collected data to check whether a storage expansion could make sense in order to make the Hacker family even more self-sufficient. By just using one VoltStorage system, the family has already been able to significantly increase their degree of self-sufficiency. In September 2019, for example, it was possible for the Hacker family to cover 95% of their electricity demand from self-produced solar power, enabling them to be almost completely self-sufficient.
