NOVELTY - The holding frame for solar module (2) and/or photovoltaic modules, is claimed, where the holding frame is partially formed from polymer concrete with silicone and/or acrylic resin and/or polyester resin (20%) as binding agent and quartz sand (80%). Four frame elements formed from the polymer concrete, where each two frame elements are arranged next to each other and each two frame elements are arranged one behind the other, where both the frame elements arranged next to each other and the sequentially arranged frame elements are connected together over an elongated connection element.    USE - The holding frame is useful for solar module and/or photovoltaic modules.    ADVANTAGE - The holding frame ensures simple solar module and/or photovoltaic modules with improved thermal insulation and high stability.    DETAILED DESCRIPTION - The holding frame for solar module (2) and/or photovoltaic modules, is claimed, where the holding frame is partially formed from polymer concrete with silicone and/or acrylic resin and/or polyester resin (20%) as binding agent and quartz sand (80%). Four frame elements formed from the polymer concrete, where each two frame elements are arranged next to each other and each two frame elements are arranged one behind the other, where both the frame elements arranged next to each other and the sequentially arranged frame elements are connected together over an elongated connection element e.g. connection sheet such as aluminum. The frame elements comprise a base such as an elongated footplate for mounting on a substrate and/or a diagonally upward running module support portion such an elongated support strip, where the base and the module support portion are connected together at its both end over a forward mounting section and/or a rear mounting section for mounting the connection element. The frame elements arranged next to each other at its rear mounting section and such as at its forward mounting section is connected together by the elongated connection elements, where the frame elements are screwed together with the connection elements by self-tapping screws. The connection elements are adapted through tilting of its longitudinal sides at the form of the mounting sections of the frame elements. Both the forward mounting section and the rear mounting section extend over the module support portion, where the mounting sections have a recess in the lower region e.g. notch. The frame elements have amplification walls arranged laterally, where the amplification walls have recesses. The frame element arranged next to each other and the connection element connected together have a U-shaped cross-section. An INDEPENDENT CLAIM is included for a kit for building a holding frame.
