Arrangement and method for utilizing the heat built up on photovoltaic systems of domestic installations

Method for utilizing the heat generated at photovoltaic systems inside building systems, wherein the commercially available photovoltaic modules are used on sloped surfaces, in particular on roofs,

• wherein the hot air that is generated under the photovoltaic modules (1) is passed between them and the upper side of the sloped surface or more specifically the roof membrane (9) in channels (3) comprising the controllable squirrel cage fans (4′), which are disposed at the bottom or top of said channels, to the roof ridge upper edge or rather the upper edge of the sloped surface (9), so that the structured elements (12) swirl this air which, as a result, on the one hand cools the photovoltaic modules (1) and, on the other hand, absorbs their thermal energy for energetic utilization,
• that there at the top the air is drawn off over the individual shafts by means of the collecting channel (6), located at said top, through the suction ports, which are located in said channel and which are provided with controllable squirrel cage fans (4′), and the ventilator (5), which may be disposed there, and that then said air is passed by means of an additional air channel (7) having an integrated suction/pressure ventilator into the multiport air mixer (8) for the purpose of being delivered to an air/water heat pump (10) or into the building/house ventilation system (11) or the building body itself—for example, the basement and the stairwell.
