    1 Roof receives solar energy.
    The present invention relates to a roof for absorbing solar energy. The invention is particularly lamped for a building with a roof with a roof tile, but not limited to this method. The invention is arranged for single-family houses and correspondingly smaller buildings, but can also be used for larger buildings with roof tiles. w SolfOngare Or kanda in many different designs. Most solar panels are challenging to be mounted on a roof, at a certain angle to the horizontal plane, which does not correspond to the slope of the roof to the horizontal plane. One problem is that this makes the solar panels less aesthetically pleasing.
    A type of solar collector that is common includes relatively flat panels, where a rudder runs back and forth on a board and where the rudder on a panel is connected in series or in parallel with an adjacent panel, so that a number of panels cooperate. The panels can be challenging in metal or plastic.
    One problem is that such solar collectors have a very high heat capacity for storing heat. Therefore, the panels cool relatively quickly when unheated water is supplied to the panels.
    There are also solar panels with solar cells to convert sunlight into electrical energy. Such solar panels are available for mounting on ceilings. A problem with such solar panels is that the efficiency drops at higher temperatures, such as exceeding, for example, 80 ° C. In sunny weather and especially in the summer Is this a problem.
    Application text. docx 2012-03-08120006EN 2 Dangerous invention solves the latter problem and offers a device for generating both hot water and electricity with high efficiency.
    The present invention thus relates to a solar collector and solar panel with solar cells for the roof of a building, which solar collector is arranged to heat water by means of the sun, which is supplied to the solar collector and which flows through channels or pipes through the solar collector, where the solar collector is arranged to supply heated water. to the building's water supply system, and is distinguished by the fact that the solar collector comprises modules of solid material, by the modules Or being provided with one or more channels or pipes running inside the modules, by the materials of the modules having a heat capacity of at least one / 5 black rubber material and by the solar collector exterior comprises light-transmissive roof tiles with a size corresponding to conventional tiles and of the fact that solar panels for generating electrical energy are present on the water side of the modules towards the roof tiles.
    The invention is described in more detail below, partly in connection with an exemplary embodiment of the invention shown in the accompanying drawings, in which Figure 1 shows a boiler belonging to the invention - Figure 2 shows a module belonging to the invention. Figure 3 shows a cross section of a solar collector according to the invention. , which runs on a roof in the direction of the roof slope - figure 5 schematically shows a block diagram and a flow circuit.
    Application text. docx 2012-03-08120006EN 3 Figures 1 and 2 schematically show a part of a solar collector and a solar panel with solar cells for a building with a roof with a tiled roof, hereinafter referred to as a solar collector. The solar collector Or arranged to heat water by means of the sun, which is supplied to the solar collector and which flows through channels or through the solar collector via channels, where the solar collector is arranged to supply heated water to the building's water supply system.
    The invention is described below in the case where the building has a brick roof, but the invention is not limited to such a case.
    According to a preferred embodiment of the invention, the solar collector comprises modules 1 with a width corresponding to the distance between the roof ledge 2, 3 which runs from the ridge to the eaves and with a height which corresponds to the thickness of the said roof ledge 2, 3. The modules 1 are of solid material and Or are provided with one or more channels 4, 5, 6 running inside the modules in a direction parallel to said lath.
    The material of the modules is chosen so that the material has a relatively high heat capacity, so that the material can emit heat after heating, while the solar radiation is weak. Example of a material Or a black rubber material of the type used in conveyor belts, such as ore conveyor belts. Of course, other well-suited materials can of course also be used.
    The exterior of the solar collector comprises light-transmissive tiles 7 with a size corresponding to conventional tiles.
    Figure 3 illustrates a module 1 lying on a roof 8 between two layers 2, 3. Above the layer 2, 3 there is, as is conventional, a number of inboard parallel roof layers 9, which run perpendicular to the application text. docx 2012-03-08120006EN 4 against the said lath 2, 3 and which has the purpose of supporting tiles.
    According to a preferred embodiment, said light-transmissive pans 7 are made of glass. These tiles have the same shape as conventional tiles. Conventional tiles have a smaller number of standardized shapes. In the figures, the boilers 7 are illustrated with a so-called two-cup roof tile. It is preferred that the channels 4, 5, 6 of the modules 1 consist of tubular channels inside the modules 1 and that the channels of the adjacent modules 1 are joined to each other with tubes 10, 11, 12 inserted one piece in the respective module 1, as illustrated in figure 4, where said rudders are shown in broken lines. Rö-, 11, 12 are tat against the respective module.
    Modules 1 can thus be placed from eaves to eaves and connected to each other by means of said pipes.
    An alternative preferred embodiment is that said channels in the modules 1 consist of tubes 13, 14, 15 with a length corresponding to the total length of the modules 1 in the direction of the roof pitch. Such tubes have an outer diameter which corresponds to the diameter of the channels. During assembly, such pipes are pushed through the current number of modules. Alternatively, the modules 1 are divided, as illustrated by the broken line 18 in Figure 3. In the lower and upper part of the module, respectively, a groove is accommodated which, when the module halves are laid against each other, corresponds to the outer diameter of the tubes 4, 5, 6.
    It is further preferred that said tubes are made of a corrosion-resistant material, such as copper or aluminum.
    Application text. docx 2012-03-08120006EN Named ducts 4, 5, 6 or pipes running in the ducts, are connected at the eaves and ridge so that a flow circuit 19 is formed, which is connected to the building's water supply system in a suitable 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 entering a flow circuit in the building, see figure 5.
    When installing a number of modules, the existing tiles are removed where the modules are to be laid, after which light-transmissive tiles are laid where the ordinary tiles have been removed. This gives a smooth roof corresponding to what is available for mounting modules and light-transmissive boilers. Furthermore, the lactate is not required to be amputated or changed.
    Because the modules 1 Or of a material with a high heat capacity, these will accumulate heat energy during solar radiation.
    The heat energy in the modules is then transferred to the water flowing in the modules, whereby heated water can be led to said heat exchanger 20. An adjustment of the number of modules takes place depending on the desired volume of heated water.
    According to the invention, there are also solar panels 16 for generating electrical energy on the wet side of the modules 1 towards the roof tile 7. The solar panels Or of suitable edge type. Each solar panel Or equipped with electrical conductors 17 to be connected to each other and to a consumable st011e for electric current.
    Lampligen Or the solar panels 16 connected to the ordinary electricity network to supply electricity to the electricity network.
    Application text. docx 2012-03-08120006EN 6 As was initially mentioned, the efficiency of the solar cells decreases when the temperature becomes too high, for example 80 ° C. The temperature (Jar efficiency drops below varies between different solar cells).
    Because the solar panels 16 are directly attached to the modules 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 combination of heat-absorbing modules 1 from the sunlight which are cooled by the circulating circuit 19 with solar panels 16 generating electricity from the sunlight which abut against the modules 1 means that heat and electricity are generated with good efficiency.
    Furthermore, the solar panels are protected by the light-transparent roof tiles.
    However, as initially stated, the modules can assume a temperature in sunny weather, especially in the summer, as Or so high that the efficiency of the solar panels decreases.
    According to a preferred embodiment, the flow circuit 19 formed by said channels or tubes 4,5,6 is selectively connectable to a cooler 23 arranged to cool heated water in the flow circuit. As a result, the temperature in the flow circuit and thus the temperature of the solar panels can be lowered to a level where the efficiency of the solar panels is high.
    The cooler 23 can be connected to the lines 24, 25 of the flow circuit 19 to the said heat exchanger via valves 26, 27.
    The valves Or are arranged so that the flow circuit Or is connected to the said heat exchanger 20 or to the radiator 23 or to both.
    Application text. docx 2012-03-08120006EN 7 According to another preferred embodiment there is a temperature sensor 28 for measuring the temperature in the flow circuit 19. A control circuit 21 is also provided which is arranged to control a pump 22 arranged to pump water through the flow circuit 19 depending on the temperature. of the water, said that the temperature does not exceed a predetermined temperature. The predetermined temperature Or the highest ddr solar panels have an acceptable efficiency. The present invention thus solves the problems mentioned in the introduction.
    A number of embodiments have been described above. In particular, a modular system has been described. The present invention can, however, be carried out with a system other than a modular system, such as a system in which the said rubber material with internal tubes is laid on a whole roof before the roof is covered and the solar panels are laid between the roofs. The invention can be varied, for example Regarding the number of channels in the modules, choice of material with regard to pipes, etc.
    The present invention is, therefore, not to be construed as limited to the embodiments set forth above, but may be varied within the scope of the appended claims.
