Abstract: The invention relates to a mounting system, which is configured for mounting at least one photovoltaic module (20) and a solar collector (30) on a substructure suitable therefor. The mounting system (1) comprises at least one U-shaped mounting carrier (2) for fastening the at least one photovoltaic module (20) and for accommodating at least one solar collector (30), the U-shaped mounting support being fastened to the substructure by means of a mounting rail (3), wherein the mounting carrier (2) has support clamping receptacles (9) for fastening the at least one photovoltaic module (20) to at least one of the outer surfaces of the mounting carrier.

Abstract: The invention relates to a device for conversion of energy, to a module for storage of energy, and to a method for conversion and storage of energy, in which provision is made that at least one module, which is designed to store mechanical energy, is held in a number of holding stations of at least one device which is designed for conversion of energy, such that the least one module, which is held in one of the holding stations, is connected simultaneously via a transmission of the at least one device to a first energy converter and to a second energy converter, such that it is possible simultaneously to transfer energy from the first energy converter to the at least one module and to transfer energy from the at least one module to the second energy converter.
