Abstract: A method of manufacturing a transparent pane, in particular a glass pane, which includes on at least one of its main surfaces a surface structure including an assembly of specified individual motifs in relief, in particular pyramids, cones, or truncated cones, created by embossing or by rolling. A structure is created on the surface of the pane constituted by individual motifs, based on one or more basic motifs but which are distinguished from each other by their depth, their height, and/or the perimeter of their base area, and/or by the position of their peak with respect to their base. With this variation, formation of intensity peaks of the reflected light is prevented and at the same time a high quality of light trapping is obtained by panes suitable, for example, for solar applications.

Abstract: A method for operating a hybrid power plant comprising fuel-operated heating and solar energy heating of carrier fluids, wherein a first portion of total power provided by the power plant is based on fuel-operated heating of carrier fluids and a second portion of the total power is based on solar energy heating of carrier fluids, the heat absorbed by a solar energy heated carrier fluid is transferred to a carrier fluid circuit of a fuel-operated part of the power plant. When a sudden increase or reduction of the total power provided by the power plant is required as compared to a basic state, the second portion is first increased or reduced over a short time period in order to provide a positive or negative reserve power. Subsequently, the first portion is slowly increased or reduced and the second portion based on solar energy heating is correspondingly reduced or increased again.
