A photovoltaic system (10) comprising planar photovoltaic elements (12), the top of which is hit by solar irradiation (S) such that electricity is generated that is fed into a power grid (14) and/or is supplied to a battery unit, is characterized in that a cooling coil (20) that communicates with a first heat pump via a heat pump cycle is arranged below each photovoltaic element (12). Said cooling coil (20) feeds the process heat generated during operation of the photovoltaic element (12) to the first heat pump which communicates with a first carrier medium cycle (22) containing a first carrier medium. Furthermore, a heat accumulator unit (24) containing a heat accumulating medium is arranged in the first carrier medium cycle (22), the thermal energy of the first carrier medium being transferred to the heat accumulating medium within the heat accumulator unit (24). In addition, at least one other heat consumer cycle (30) containing a second carrier medium communicates with the heat accumulator unit (24), and the thermal energy of the heat accumulating medium is transferred to the second carrier medium of the other heat consumer cycle (30) as needed. |
