Abstract: The invention relates to a mounting system, in particular for solar modules (1), consisting of supports (2) with a closed hollow box profile (3), with connectors (4) for solar module fastening means, and connectors (5) for roof fastening means. At least the connectors (4) for the solar module fastening means are formed from longitudinal groove pairs—or longitudinal flange pairs in or on the hollow box profile (3) that are arranged at a distance from each other. The fastening means for the solar module (1) or solar modules (1) in the area of the support consist of a clamping piece with a shaped part (8), with each shaped part (8) having at least two webs (9.1, 9.2), arranged opposite each other on the shaped part (8) whereby at least one positive click connection with one of the groove pair—or flange pairs can be made by means of the ends remote from the shaped part (8), and the shaped part (8) has at least one bore hole (11) for the insertion of a fastening bolt (14).

Abstract: Disclosed is a fixture for external frame sections (1) of solar modules on a profiled support (2). Said fixture comprises a clamping piece support (3) which can be moved in a guided manner on the profiled support (2) in the longitudinal direction of the profiled support (2) and can be braced with the profiled support (2) so as to enclose a frame section (1) of the solar module and a clamping piece (4) that is guided within the clamping piece support (3). The clamping piece (4) is designed as a double-angled profiled element which has legs (4.1, 4.2) extending in opposite directions. The upper leg (4.1) embraces the frame section (1) of the solar module while the lower leg (4.2) is disposed in and on the clamping piece support (3) so as to be vertically adjustable in a guided manner in the moving direction (7).

Abstract: The control of users and generators of electrical energy behind the legal interface with the energy provider. In particular, the invention relates to the generation of renewable electrical energy, such as wind energy, solar energy, energy from biogas plants, geothermal energy etc., and to the electricity thus generated. The proposed technical energy management avoids feeding energy into the central grid without precluding the use of energy from the central power grid if necessary.
