Definitions
- the present invention relates to a solar collector device according to the preamble of patent claim 1.
- thermal collectors for converting solar radiation into heat
- photovoltaic collectors for converting solar radiation into electrical energy.
- a heat transfer medium for example a glycol water mixture
- collector modules with a heat exchange chamber, through which the heat transfer medium flows, have proven their worth. Since the pressure prevailing in the chamber can be relatively high, ribbed plates are preferably used to form the chamber.
- Photovoltaic collector modules generally consist of a flat carrier on which solar cells connected in parallel or in series are arranged. To protect against the effects of the weather, the solar cells are covered with a translucent protective element, usually with a film or a glass pane. Furthermore, solar module modules are known which combine both collector types in one housing. These sandwich-type solar module modules are highly efficient because the heat transfer medium is also used as a coolant for the solar cells. Such combined solar module modules are known, for example, from DE-A- '120' 943, DE-A-4'206'931 and DE-A-4 '222' 806. A relatively large, sunlit collector area is required for energy conversion by means of solar energy for both types of solar collectors.
- the solar panel modules are preferably installed on roofs or integrated into the facades of buildings. Installation in inclined surfaces, for example in roofs, is to be preferred, since the choice of an ideal angle dependent on the degree of latitude maximizes the solar radiation acting on the solar collector.
- the generally cuboid-shaped solar unit modules are placed in a checkerboard-like manner on a waterproof sub-roof area in accordance with the prior art, and the joints between the individual modules are sealed.
- the individual modules are also connected to one another with conduit elements.
- the modules according to the prior art have the disadvantage that their assembly is time-consuming and requires careful work, especially for the joint seals.
- Each solar collector module has an active parallelepiped-shaped unit with thermal and photovoltaic collectors, which is structured as follows in the direction of solar radiation: Three flat glasses arranged one behind the other form two air or vacuum chambers, which are followed by a heat-exchange chamber of a first thermal collector, which is also translucent and carries a heat exchange medium. Behind this first thermal collector, the solar cells of a photovoltaic collector are arranged, the blackened back of which forms a thermal dark radiator. A second thermal collector is arranged behind the photovoltaic collector. A fastening unit is attached behind this active cuboid unit.
- the solar collector module disclosed in DE-A-4 '210' 975 has the disadvantages of a complex, expensive, heavy and also not very pressure-resistant construction.
- the solar collector device has only thermal collectors.
- Each solar collector module is plugged together with adjacent solar collector modules arranged further up and down in the sloping roof, the plug connection simultaneously forming a connecting line for a heat transfer medium flowing through the thermal collectors.
- the assembly is very easy. It will also no additional line coupling elements are required to connect the individual thermal collectors.
- the fastening unit forms a cantilevered extension plate of the pluggable active collector unit
- a shingle-like covering is present which forms a weather-resistant roof skin or facade without additional joint seals.
- the solar module modules according to the invention can thus be used instead of roof tiles or shingles to cover a roof.
- a good double covering is sufficient for the solar collector device according to the invention.
- the individual solar module modules can preferably be mutually fixed with fastening means, the fastening units in one row being connectable to active collector units in the next but one upper row, so that an intermediate module connecting the heat exchange chambers of the upper and lower rows is transitions.
- the fastening means are preferably snap elements such as resilient plastic hooks which engage past the solar collector modules of the row in between and the modules of the next row above. As a result, the individual modules can be anchored to one another without screw or rivet connections and without using any tools.
- thermal collectors are preferably formed by heat exchange chambers, the opposite side surfaces of which contact one another in a punctiform manner. As with the ribbed sheet, this creates a pressure-resistant chamber. In contrast to the ribbed sheet, however, an improved wetting of the chamber walls and thus a better heat transfer is achieved.
- the active collector unit has both thermal and photovoltaic collectors.
- the photocells of the photovoltaic collector are preferably arranged on the sunlit front of the thermal collector, the electrical lines being protected on the fastening unit. This arrangement makes it possible to use simple electrical connecting elements, which are also attached to the fastening unit.

- Figure lb is a view of the solar panel module according to Figure la from below;
- Figure 2 shows a longitudinal section through the solar panel module according to Figure la along A-A and shown with broken lines a longitudinal section along B-B;
- FIG. 3 shows a view of solar collector modules assembled to form a solar collector device
- FIG. 4 shows a longitudinal section through the solar collector device according to FIG. 3;
- FIG. 5a shows a view of a solar collector module according to the invention with serial wiring from above, the wiring being shown in broken lines;
- FIG. 5b shows a view of a solar collector module according to the invention with parallel cabling from above, the cabling being shown in broken lines;
- FIG. 6 shows a view of solar collector modules assembled to form a solar collector device in accordance with a further embodiment of the invention.
- the inventive solar collector module according to the figures la, lb, 2, 5a and 5b has a support plate 1, which is divided into an upper and a lower section.
- the upper section forms a fastening plate or fastening unit 2
- the lower section is part of an active collector unit 3 with thermal 30 and photovoltaic collectors 31.
- the carrier plate 1 is essentially flat and rectangular and consists of a metal, preferably of chromium steel.
- the fastening unit 2 has an upper edge 20 which is at least approximately perpendicular to the roof surface. opposite front is bent. Furthermore, fastening bores 21 for fastening the fastening unit to a building surface, for example to roof battens or to the facade, are provided in the region of the upper edge.
- the active collector unit comprises at least one, here two separate, adjacent thermal collectors 30 and at least one photovoltaic collector 31.
- the thermal collector 30 has a heat exchange chamber 301, which is formed by the carrier plate 1 on the one hand and a wetting plate 302 attached to it in a fluid-tight manner .
- the wetting plate 302 is preferably also made of chrome steel. It can be formed by a rib plate welded onto the carrier plate 1 or, as shown here, by a profiled plate welded on in a punctiform manner.
- the spot welding points are designated in the figures with the reference number 303.
- the rear side of the active collector unit 3 and thus the wetting plate 302 are provided with thermal insulation 4, preferably foamed, for which purpose the curved lower edges 37 offer retention.
- Connections that flow into the heat exchange chamber 301 of the thermal collector serve as connecting elements to neighboring solar collector modules.
- the sockets 34 have a weatherproof seal, preferably one Provided plastic molded part 35, which ensures tightness even in the event of heat-affected dilatation of the modules.
- the pin can also be arranged on the back of the support plate and the nozzle on the front.
- this weather-resistant seal consists of a rubber ring with a U-shaped cross section, which has an integrated metal spring element.
- This spring element is held in the U-shaped groove, the opening of which is directed towards the heat exchange chamber. When pressurized, the spring element spreads the rubber ring and presses its side walls onto one connection each.
- the photovoltaic collector 31 is arranged on a front side of the carrier plate 1 facing away from the roof surface and essentially consists of solar cells 310 which are fastened to the carrier plate 1 via a dielectric but heat-conducting layer. Electrical lines 311 are laid on the front side of the fastening unit 2 and end at the side edges thereof in plug elements 312. On each fastening unit 2 there is a male plug element on one side edge and a female part on the opposite edge.
- the electrical connecting elements 313, 314 are shaped such that the electrical connection can be closed or opened by moving a module vertically to the plane of the carrier plate 1. It is obvious to the person skilled in the art that this type of contact connection can be established by means of contact knives or other advantageously spring-loaded contact connections. However, it is necessary to establish an electrical connection with neighboring ones Solar collector modules of the same series, the positioning of the contact elements 313, 313 'and 314, 314' in the horizontal and the vertical is coordinated. This ensures that the neighboring modules in a row are electrically connected to each other and that a possibly damaged module can be easily replaced or removed and reinstalled after the repair.
- the cabling 311, 311 'of the photovoltaic elements 310 can be designed for a series or parallel connection of the adjacent modules. In the case of a series connection, it would suffice to accommodate the lines 311 and the electrical connecting elements 313 and 314 on the module and to close the circuit apart from the modules. This would reduce the production costs of the collector modules.
- the solar cells 310 are covered by a translucent film 5, which preferably extends at least partially over the electrical connection lines 311 and in the area of the solar cells 310 to the lower curved edges 37 of the carrier plate 1 and at least partially through the foamed thermal insulation 4 is covered and thus fixed.
- FIGS. 3 and 4 show a detail with a middle row I, an upper row II and a lower row III. A second and a third solar collector module b of the next row II can be plugged onto a first solar collector module a of the middle row I, only the second being drawn here.
- the sockets 34 of the second and third solar module b coming to lie above are placed over the pin 33 of the middle first module a, whereby a tight connection line is established between the thermal collectors, the direction of flow preferably being by means of pumps or by a siphon effect from bottom to top.
- the first module a can be plugged onto a fourth and fifth solar collector module c of a lower row III.
- the connections 33, 34 are preferably arranged at a distance from one another in such a way that the modules of a row touch one another.
- the active collector units 3 overlap in a small section, but the photovoltaic collector 31 is not covered.
- the individual photovoltaic collectors 31 are electrically connected via the plug elements 312, which connect adjacent modules of the same row to one another.
- the length of the fastening unit 2 is dimensioned such that it extends from the lower module row III over the middle module row I to the next but one upper module row II.
- the collector modules of the rows III, I and II thus overlap three times in connection areas V. In these areas V, V, V ', the modules are connected to one another in a positive or non-positive manner.
- the hook-shaped snap elements 6 penetrate the hook passage cutouts 22 of the next module row and are detachably hooked into the hooking profiles 32 of the next module row after that.
- the mechanical securing of the connection between connecting piece 34 and pin 33 of two directly superimposed modules of layers I and II thus takes place indirectly via the form-fitting connection between modules of layers III and II.
- the height of the hook 6 is dimensioned such that, for example, the upper one Bending 20 of the module of position III can act as an abutment, and bending of the module of the row I is counteracted.
- FIGS. 1 a, 1 b, 2 and 3, FIG. 2 showing that at least one mounting profile 24 is attached to the mounting unit 2.
- a mounting profile 24 which is arranged centrally in the region of the upper edge.
- em hook-shaped snap element 6 can be inserted, which preferably consists of a resilient, weather-resistant molded plastic part. Its meaning is explained in more detail below with reference to FIGS. 3 and 4.
- the fastening unit has side hook bushings 22 in the form of notches.
- At least one hooking profile 32 is arranged on the back of the active collector unit 3. In this example, it is located in the lower area in the middle between the two thermal collectors 30.
- the hooking profile 32 and the mounting profile 24 are preferably ⁇ profiles.
- the directly superimposed collector modules can also be connected to one another in a form-fitting manner in the connection area V, as is shown in FIG. 6.
- the connecting elements can be attached where the hydrostatic forces, which arise from the system pressure or from heating and the resulting expansion of the heat exchange medium, could loosen the connection between the active collector units 3.
- the immediate vicinity between connecting piece 34 and pin 33 can take up the forces where they arise and thus counteract them effectively.
- two mechanical connections are made.
- connection elements 601, 602 connect the fastening part 2 of the module c located in the lower row III to the active unit of the module a located directly above it.
- the connecting element of the lower module c can advantageously be formed by the upper edge 20. For this purpose, it has cutouts into which the connecting elements 601 of the module above it can hook or snap into place. The hooking or snapping takes place approximately horizontally to the level of the support plate 1, so that the finished connection prevents vertical movement in a form-fitting manner.
- the second mechanical connection is made by elements 603 and 604 between modules a and b.
- a circumferential profile 603 for receiving a fastening element 604 ′′ is attached to the pin 33.
- the fastening element 604 ′′ can be a spring-loaded bolt or pin that snaps over the profile 603 when assembled, or in the simplest case a screw that is screwed in so far that it comes to rest under the profile 603.
- the fastening element 604 ′′ is mounted in the front bend 37 ′′ of the active unit of the module c.
- the finished connection in turn prevents vertical movement of the modules a and b to one another. Water penetrating between the modules runs down the shingle surfaces, as is known with the shingle roofs, until it is collected in the gutter R.
- the upper fold 20 of the fastening unit prevents the water from being pushed upwards by the wind.
- Transition fastening modules 7 and transition connection modules 8 are provided for fastening and connecting modules at the edge which do not have adjacent modules on all sides, as can be seen in FIG. 4.
- the transition modules 7 have a fastening plate 70 with two snap elements 71 for fixing the first and second modules and a pair of male connections 72.
- the transition connection module 8 has a pair of female connections 80.
