Popis: Energy storage devices can be used in combination with residential photovoltaic (PV) systems to further improve the energy self-sufficiency and self-consumption. This paper demonstrates the effect of a flywheel energy storage system (FESS) in residential PV installations. The purpose is to give a quantitative evaluation with emphasis on energy efficiency. For this purpose, a loss-model of a FESS is derived. Based on load and generation profiles of a one-family house with a roof mounted PV system, the effect of a 3 kWh FESS on the energy performance is analyzed. The influence of the FESS capacity and the losses are discussed. The results show that the overall energy efficiency of the FESS for PV is typically less than 40% for optimistic loss estimations.
