Definitions

• the present invention relates to a roof for absorbing solar energy.
• the invention is particularly suitable for a building with a roof with roofing tiles, but is not limited to such embodiment.
• the invention is intended for single- family houses and corresponding smaller buildings, but is also applicable in larger buildings with roofing tiles.
• Solar collectors are known with many different designs. Most solar collectors are designed for on-roof assembly, with a certain angle in relation to the horizontal plane, which does not correspond to the inclination of the roof in relation to the horizontal plane. A problem is that this results in that the solar collectors are aesthetically less appealing.
• One common type of solar collector comprises relatively flat panels, wherein a pipe runs back and forth on a sheet, and wherein the pipe on one panel is connected in series or in parallel with a neighboring panel, so that a number of panels cooperate.
• the panels may be made from metal or plastic.
• solar panels with solar cells for transforming solar light into electrical energy.
• solar panels are available for mounting on roofs.
• a problem with such solar panels is that the efficiency decreases at higher temperatures, such as exceeding for instance 80 °C. During sunny weather, and in particular during the summer, this is a problem.
• the present invention solves the latter problem, and offers a device for generating both hot water and electricity with high efficiency.
• the present invention relates to a solar collector and solar panel with solar cells for the roof of a building, which solar collector is arranged to, using solar energy, heat water which is supplied to the solar collector and which, via channels or pipes, runs through the solar collector, wherein the solar collector is arranged to supply heated water to the water pipe system of the building, and is char- acterised in that the solar collector comprises modules of massive material, in that the modules are provided with one or several channels or pipes running inside the modules, in that the material of the modules has a thermal capacity which at least corresponds to a black rubber material, and in that the exterior of the solar collector comprises translucent roofing tiles with a size corresponding to conventional brick roofing tiles, and in that solar panels for generating electrical energy are arranged on the side of the modules facing the roofing tiles.
• FIG. 3 shows a cross-section of a solar collector according to the invention
• FIG. 4 shows modules between roof laths, running on a roof in the direction of the sloping of the roof
• FIG. 5 schematically shows a block diagram and a flow circuit .
• FIG. 1 a part of a solar collector and solar panel with solar cells for a building with a roof with roofing tiles, below denoted solar collector, is schematically shown.
• the solar collector is arranged to heat water using solar energy, which water is supplied to the solar collector and which, via channels or pipes, flow through the solar collector, where the solar collector is arranged to supply heated water to the water work system of the building.
• the invention is described for the case in which the building has a tiled roof, but the invention is not limited to such a case.
• the solar collector comprises modules 1 with a width corresponding to the distance between roof laths 2, 3, running from the ridge to the base of the roof and with a height corresponding to the thickness of said roof laths 2, 3.
• the modules 1 are made of solid material and are provided with one or several channels 4, 5, 6, running within the modules in a direction which is parallel to the said roof laths.
• the material of the modules is selected so that the material has a relatively high heat capacity, so that the material after heating can emit heat when the solar radiation influx is weak.
• An example of materials is a black rubber material of the type used in conveyor belts, such as ore conveyor belts. Of course, other suitable known materials can also be used.
• the exterior of the solar collector comprises translucent tiles 7 with a size corresponding to conventional brick roofing tiles.
• a module 1 is illustrated lying on a roof 8 between two roof laths 2, 3.
• the said translucent tiles 7 are made of glass. These tiles have the same shape as conventional brick tiles. Conventional brick tiles have a small number of standardized shapes. In the figures, the tiles 7 are illustrated with a so called double pantile (sv. "tvakupig") shape.
• the channels 4, 5, 6 of the modules 1 are constituted by tube-shaped channels within the modules 1, and that channels of adjacent modules 1 are joined together by pipes 10, 11, 12, inserted some distance into the respec- tive module, as illustrated in figure 4, in which the said pipes are shown using broken lines.
• the pipes 10, 11, 12 are sealed to the respective module.
• modules 1 can be positioned from roof base to roof ridge, and can be connected to each other using said pipes.
• the said channels in the modules 1 are constituted by pipes 13, 14, 15 with a length corresponding to the total length of the modules 1 in the direction of the roof sloping.
• Such pipes have an outer diameter corresponding to the diameter of the channels.
• the modules 1 are made in a separated fashion, as is illustrated by the broken line 18 in figure 3.
• a chamfer is thereby provided, which corresponds to the external diameter of the pipes 4, 5, 6 when the module halves are positioned next to each other.
• the said pipes are constituted by a corrosion resistant material, such as copper or aluminum.
• the said channels 4, 5, 6 or pipes running inside the channels are connected at the roof ridge and roof base, so that a flow circuit 19 is formed, which is connected to the water work system of the building in a suitable known manner.
• the flow circuit 19 can be connected to a heat exchanger 20 in the building, where the heat of the water is heat exchanged to a heat exchanger which is part of a flow circuit in the building, see figure 5.
• the existing roofing tiles are removed from places in which modules are to be mounted, after which translucent tiles are positioned in locations where the regular tiles have been removed. This achieves a flat roof corresponding to the one present before the mounting of modules and translucent tiles. Furthermore, it is not necessary to reinstall or modify the roofing laths.
• the modules 1 are made from a material with high heat capacity, these will accumulate thermal energy from solar incident radiation. Hereby, the thermal energy in the modules are transferred to the water flowing in the modules, whereby heated water can be led to the said heat exchanger 20.
• An adaptation of the number of modules takes place as a function of the desired volume of heated water.
• solar panels 16 for generating electrical energy on the side of the modules 1 facing the roofing tile 7.
• the solar panels are of suitable known type.
• Each solar panel is provided with electrical conductors 17 for being connected to each other and to a place of consumption of electrical current.
• the solar panels 16 are connected to the ordinary electricity supply network in order to deliver current to the electricity supply network.
• the efficiency of the solar cells decreases as the temperature becomes too high, for instance 80 °C.
• the temperature at which the efficiency decreases varies across different solar cells.
• the solar panels 16 Since the solar panels 16 are arranged directly on the modules, being cooled by the water in the flow circuit 19, the solar panels 16 will also be cooled so that their efficiency can be maintained.
• the solar panels are protected by the translucent roofing tiles.
• the modules may assume a temperature during sunny weather, especially during the summer, which is so high so that the efficiency of the solar panels decreases.
• the flow circuit 19, formed of the said channels or pipes 4, 5, 6, is therefore selectively connectable to a cooler 23, arranged to cool heated water in the flow circuit.
• a cooler 23 can be connected to the conduits 24, 25 of the flow circuit 19 to the said heat exchanger via valves 26, 27.
• the valves are so arranged so that the flow circuit is connected to the said heat exchanger 20 or to the cooler 23, or to both.
• a temperature sensor 28 for measuring the temperature in the flow circuit 19.
• a control circuit 21 is also provided, arranged to control a pump 22, in turn arranged to pump water through the flow circuit 19 depending upon the temperature of the water, so that the temperature does not rise above a predetermined temperature.
• the predetermined temperature is the highest at which the solar panels have an acceptable efficiency.
• the present invention solves the initially mentioned problems .
• a module system has been described.
• the present invention can be implemented with a different system than a module system, such as a system in which the said rubber material with internal pipes is positioned on a complete roof before lathing is installed on the roof, and wherein the solar panels are positioned between the laths.
• the invention may be varied, for example also as regards the number of channels in the modules, choice of pipe material, etc .
