The PV battery system was installed in the EnergyFlexHouse at Danish Technological Institute, a full-scale flexible measurement platform for construction and installation technology.
This gave the possibility to test the PV battery system in a single-family house environment. The PV battery system was connected to a PV array of 3.5 kWp. High resolution consumptions data for typical single family households was used for minute by minute load simulation in the tested PV battery system. Economic calculations based on Danish feed in tariffs are calculated for a PV battery system and a PV system without battery to clarify if it is profitable for a Danish consumer to install a PV battery. Economic calculations show that a PV battery system could potentially stimulate the demand for PV systems despite decreasing feed in tariffs.
