Almost energy-autonomous The photovoltaic modules are part of the overall energy concept of the housing complex. Most of the hot water and heating is produced by a system of solar panels on the roof, a heat pump system and a geothermal reservoir. The photovoltaic elements are also connected directly to the heat pump and significantly increase the overall efficiency of the system. Excess solar energy is supplied and stored into a geothermal brine reservoir during the sunny months. This energy is then released during colder months and latched into the heat pump system and made usable for heating. Only a small proportion of energy is required in the form of electricity for the heat pump and district heating for higher temperatures to support the water heating by external providers.
