The invention relates to a solar energy system for installing on or in buildings having a solar thermal collector (2), which can be installed on the building, for example, on a building roof, and by means of which solar radiation can be converted into thermal energy of solar liquid, and a storage tank (3), which is connected by means of a fluid circuit (7, 8) to the solar thermal collector (2) and by means of which energy-consuming devices in the building, for example, a heating system (6), a hot water supply system (5) or the like, can be supplied with thermal energy stored in the solar liquid. In order to be able to design a solar energy system (1) in such a way that it has sufficient capacity to supply the energy-consuming devices in the building with thermal energy even in times of weak solar radiation, it is proposed for the solar energy system (1) to have a residual heat power unit (4), which is connected to the fluid circuit (7, 8) by means of which the solar thermal collector (2) and the storage tank (3) are connected, and by means of which thermal energy that is generated in the solar thermal collector (2) and cannot be stored in the storage tank (3) owing to the cooling of the solar liquid can be utilized. |
