The hybrid collector according to the invention has a special construction in order to optimize the overall efficiency of hybrid collectors. The overall efficiency of the hybrid collector is the ratio of emitted energy to supplied energy.

In this context, the application of build-up layers to the glass pane or to the surface of the glass pane means that these building layers are preferably applied to the side of the glass pane which faces away from the incident radiation or the weather.

Only in the areas of the glass pane where solar cells are located are the remaining build-up layers preferably applied for attachment and protection of the solar cell (s). The area on the glass panel with solar cells occupied areas, which may include all build-up layers as previously mentioned, called non-transparent areas.

The absorption panel further preferably comprises a selective coating to achieve an absorbance of between 85 and 98%. Preferably, the absorption plate is provided with known coatings such as EthaPlus or Tinox or Sunselect or other coatings. The absorption plate preferably has a ribbed or corrugated or curved surface, particularly preferably a smooth, planar surface. The absorption plate is preferably via a welded joint (weld), particularly preferably via a joint connection (gluing, soldering, welding, pressing, kraft- and form-locking and material-connecting compound) connected to the heat transport system. Furthermore, the absorption plate is preferably part of the heat transport system. If the heat transport system is connected to the absorption panel via a welded joint, the width of the welded joint is preferably between 0.5 mm and 10 mm, more preferably between 1 mm and 6 mm, most preferably between 2 mm and 4 mm.

The heat transport system preferably comprises at least one pipe or a pipe system or a harp. Preferred is a pipe or several tubes are connected over the entire pipe run with the absorption plate via a weld. If one imagines the hybrid collector from the top view (ie the direction of view equal to the course of the vertically incident radiation), it is preferable for tubes of the heat transport system to extend only below the cold regions of the absorption plate. Preferably, only one tube per cold area, more preferably extending several tubes parallel below a cold area, more preferably two or three or four or five or six or seven or eight tubes. A cold region preferably consists of a tube bundle, more preferably of two or three or four tube bundles. A tube bundle preferably has three to eight, particularly preferably five to six parallel running tubes. The individual tubes of a tube bundle preferably have the same distance from each other. The distance between the individual tube bundles is preferably greater than the distance between the individual tubes within a tube bundle. The tubes are preferably harfen- meänder- or circular arranged as a heat transport system. This means that a cold area can consist of several cold areas arranged next to each other.

The absorber module or the absorption plate comprises cold areas and warm areas. The cold areas are the areas of high absorption performance in contrast to the warm areas which have low absorption performance. The cold areas are preferably divided into a central area and into two edge areas.

The middle area of the cold area is the area on the absorption plate provided with the weld. The edge areas of the cold area are the areas to the right and left of the middle area. They adjoin directly to the middle area. The edge regions preferably have an area (width by length) of 2 mm by 150 mm or 2 mm by 300 mm. The middle area preferably has an area of 1 mm by 300 mm or 3 mm by 150 mm.

The cold areas are areas on the absorption plate that run along the bite seam or along the heat transfer path. portsystems, or run along the heat transfer fluid, or along the tubes or the pipe system. Preferably, the heat transfer fluid is introduced at a temperature of about -20 ⁰ C in the heat transport system 34 and discharged at a temperature of about 15O ⁰ C. Preferably, the temperature delta (outlet temperature of the cooling liquid minus the inlet temperature of the cooling liquid) is up to 200 ^° C., more preferably up to 170 ^° C., most preferably up to 140 ^° C.

The tube of the heat transport system forms in cross section preferably a circle or a semicircle, more preferably a square or a polygon or a trapezoid. If the heat transport system is designed as a pipe system with a circular pipe cross-section, then the pipe or the pipes have a diameter d of about 2 mm to 30 mm, preferably about 5 mm to 25 mm, particularly preferably about 8 mm to 18 mm ,

Due to the radiation incident from above, the PV module forms shadow regions or absorption regions through its non-transparent or transparent regions on the absorber module.

The shadow areas and absorption areas on the absorber module or the absorption panel are areas projected by the incident radiation. The length and width, or area and shape of the shadow areas or the absorption areas are directly dependent on the transparent or the non-transparent areas of the PV module.

In the case of radiation incident from above, the shadow areas on the absorption plate represent a one-to-one image of the non-transparent areas and the absorption areas are a one-to-one illustration of the transparent areas. Consequently, the absorption areas and shadow areas vary according to the angle of incidence of the incident radiation in area and shape. The absorption regions are preferably introduced into the cold regions of the absorber module or the absorptive projected onsplatte. The absorption regions are preferably projected into the cold regions by at least 70%, preferably by at least 80%, particularly preferably by at least 90%. For the example that the absorption areas are 70% in the cold areas of the absorption panel, it is assumed that 70% of the areas (area) illuminated by the incident radiation fall into the cold areas. Consequently, an intersection is formed in the form of a surface which has an area size of, for example, 70% of the projected absorption area.

If the hybrid collector is viewed in plan view (the viewing direction is equal to the radiation incident perpendicular to the hybrid collector), then each cold region of the absorber module is assigned a transparent region of the PV module, preferably facing it. From the top view, the transparent areas are preferably within the boundaries of the cold areas. That is, with perpendicularly incident radiation, the area of the transparent areas would be projected into the area of the cold areas. This would have the advantage that, even with incident angle variations of the incident radiation, the projected absorption range would be within the cold range.

From the top view, the transparent areas are particularly preferably congruent with the cold areas. That is, with perpendicularly incident radiation, the area of the transparent areas would be projected congruently onto the area of the cold areas.

Preferably, the width of the transparent region is between 0.5 × the width of the cold region and 3 × the width of the cold region. The width of the cold region is preferably measured perpendicular to the course of the possible weld on the absorption plate, or perpendicular to the course of the tubes. In other preferred attachments, such as laser or soldering, there is no weld between the absorption plate and the tube. The PV module preferably has an underside. The underside of the PV module is defined as the side facing away from the incident radiation. The underside is the side of the PV module facing the absorption plate. Preferably, the underside is a smooth surface, which includes the build-up layers on the glass plate. The distance between the bottom of the PV module and the top of the absorption plate is referred to as the length of the normal, which is perpendicular to the top of the absorption plate or on the bottom of the PV module. In this case, the smallest distance is to be assumed as a distance at parallel underside to top. This is important, for example, in a corrugated sheet-like top of the absorption plate. The distance between the upper side of the absorption plate and the underside of the PV module is preferably between 10 to 28 mm, more preferably between 20 and 27 mm, particularly preferably between 24 and 26 mm. Most preferably, the distance between the bottom of the PV module and the top of the absorption plate is 25 mm.

In a further preferred embodiment, the PV module (20) is displaceable relative to the absorber module (30) with at least one actuator (60).

This shift includes both translational and rotational movements of the PV module relative to the absorber module. In this case, the actuator can preferably be attached to the PV module, particularly preferably to the absorber module, most preferably to both modules (that is to say the PV module and the absorber module). The actuator preferably has the task of influencing the absorption range. Preferably, the absorption region is moved on the absorption plate so that the absorption region is always projected into the cold region of the absorption plate. Preferably, the entire hybrid collector moves with the course of the incident radiation or the sun's rays. Particularly preferably, the PV module always aligns perpendicular to the incident radiation, that is, the incident radiation is permanently a normal on the PV module. Furthermore, the actuator preferably aligns the non-transparent regions with respect to the cold regions. In a further preferred embodiment, the hybrid collector further comprises a tracking system (70) and a controller (80), wherein the controller (80) controls the actuator (60).

The tracking system preferably comprises a sensor which can determine the direction of the incident radiation. This sensor of the tracking system is preferably an optical sensor, particularly preferably the tracking system comprises a plurality of optical sensors. Preferably, the sensors of the tracking system collect information about the location of the origin of the incident radiation. The tracking system tracks the source of incident radiation and passes this data to the controller of the hybrid collector. Depending on the collected data of the tracking system, the PV module is moved relative to the absorber module or the entire hybrid collector.

In a further preferred embodiment, the hybrid collector (10) comprises optical elements (90) which deflect incident radiation (50) onto the cold regions (31).

As an optical element, for example, lenses, prisms, parabolic mirrors, mirrors, optical systems in general come into question. Preferably, the incident radiation is concentrated or focused on the cold areas via one or more of said optical elements.

In the description of the figures further preferred embodiments are shown. The figures show:

Figure 1 is a schematic drawing of a hybrid collector.

Figure 2 The absorption power distribution over a cross section of a tube of the absorption module.

Figure 3 Schematic drawing of a harp invention (heat transport system). FIG. 1 shows a section through a hybrid collector 10 according to the invention. The hybrid collector 10 is shown in a section through the XY plane. The absorber module 30 is arranged parallel to the PV module 20. The distance between absorber module 30 and PV module 20 is 25 mm. In the Y direction, the PV module 20 is arranged above the absorber module 30.

The PV module 20 has transparent areas 21 and non-transparent areas 22. The transparent areas 21 alternate with the non-transparent areas in strips. That is, the non-transparent areas consisting of EVA / PVB, solar cells 23, Tedlar, PET / aluminum and occupy the glass pane from the bottom in strips.

The non-transparent strips are each 150 mm wide.

In the longitudinal direction, that is to say in the Z direction, the non-transparent strips extend over the entire length of the PV module 20. The transparent regions 21, which are located between the non-transparent regions 22, consist only of glass or solar glass with or without others coating.

The absorber module 30 has a surface of the absorption plate 35, which lies opposite the underside of the PV module 20. The top of the absorption plate 35 and the bottom of the PV module 20 include an isolation space.

The absorption module has cold areas 31 which are located on the absorption plate 35. The cold areas 31 have a width bl of about 6 mm. The cold region or the cold regions 31 are again divided into a central cold region 31.1 and into a left edge region 31.3 and a right edge region 31.2. The central region 31. 1 of the cold region 31 has exactly the width of the weld seam 36 which connects the absorption plate to the tube 34. Each cold area faces a transparent area 21 of the PV module 20. The area, that is, the length and width of each cold area is identical to the opposite transparent area 21. When the incident radiation 50 is perpendicular to the Y axis of the Cartesian coordinate system, the area of the transparent area 21 projected by the radiation fills the cold area 31 across the surface. About 60% of the area of the PV module forms the non-transparent areas 22. If now the hybrid collector 10 is irradiated by the incident radiation 50, then about 60% of the incident rays are intercepted by the non-transparent areas and converted into electrical energy. converted into energy. About 40% of the vertically incident radiation 50 impinge on the cold regions 31 as the absorption region. The absorption region is thus congruent with the cold region. The vertically incident radiation is absorbed by the cold region 31, converted into thermal energy and forwarded via the weld 36 to the tubes 34, which are filled with heat transfer fluid 37. The heat transfer fluid is introduced at a temperature of about -20 ⁰ C in the heat transport system 34 and discharged at a temperature of about 15O ⁰ C.

In this case, a tube leads into the hybrid collector and is fanned out harp-shaped there, the tubes 34 then running parallel over the surface of the hybrid collector. The heat transfer fluid 37 heats up via the parallel pipe run in the hybrid collector.

Because the transparent regions are located above the cold regions of the absorption plate or of the absorber module, the particularly high absorption capacity in the cold regions can be exploited in order to achieve a particularly high efficiency of the solar collectors. By shielding the warm areas 32 from the non-transparent areas 23, the inherently low absorption power of the warm areas 32 is disregarded and replaced by a much higher electrical power, by shading the warm areas of solar cells 23. By the incident of the incident radiation 50 on the solar cell 23 electrical energy is obtained. Thus, the hybrid collector 10 according to the invention fulfills an optimal utilization of the falling radiation, that is, the incident energy through a combined conversion of wave energy into thermal and electrical energy.

FIG. 2 shows an enlarged cross section through the absorber module 30. Furthermore, FIG. 2 shows the weld seam 36 as a connection between the tube 34 and the absorption plate 35. Above the absorption plate 35, the incident radiation 50 is illustrated by arrows pointing downwards. This incident radiation 50 strikes the cold region 31 of the absorption plate 35.

The XY diagram below tube 34 shows the absorption performance curve in the form of a Gaussian bell curve. In the y-direction, the height of the absorption power can be read off. In the x-direction, the course of the absorption power is shown with increasing width bl of the cold region. It can clearly be seen that the absorption power Pmax is thus the maximum power on the absorption plate where the weld seam connects the absorption plate 35 to the tube 34.

Right and left of the weld 36, the absorption power drops. A left point Bl and a right point Br on the absorption power curve F (x) mark the width bl of the cold region, respectively, define the width of the cold region. The points Bl and Br indicate the identical absorption power in the opposite direction. The points Bl and Br are on the absorption power function where the absorption power is 25% of the maximum absorption power Pmax. However, the points Bl and Br are preferably also there on the absorption curve F (x), where the absorption capacity has between 10% and 70% of the maximum absorption capacity, preferably between 20% and 50% of the maximum absorption capacity, most preferably between 25 % and 30% of the maximum absorption capacity.

The figure shows how the cold region 31 can be defined in its width by the absorption power function. It can make a distinction between warm and cold area become. The boundary between warm and cold areas can be determined by means of the absorption power function. Has the absorption capacity in the cold region 31 only 25% of the maximum absorption capacity of the cold area. Thus, the 25% mark marks the edge, or the transition between cold area 31 and warm area 32.

If, for example, as shown in FIG. 3, several tubes 34 are placed close to one another, the absorption capacity between the individual welded connections 36 does not fall below the limit of 25% Pmax. This means that there is no warm area between two pipes, so that an area of parallel running pipes or welds can be spanned, which contains no hot areas.

FIG. 3 shows a harp of a heat transport system with 2 × 6 parallel-running tubes. Perpendicular to the 2 x 6 parallel running pipes runs an inflow or a drain pipe, which connects the 12 parallel pipes together. Via the influence tube 34.1 cold heat transfer fluid 37 is introduced. This heat transfer fluid is divided on the 12 parallel tubes 34, heats up there and is discharged via the drain pipe 34.2 from the harp. The harp has a first tube bundle 34.3 and a second tube bundle 34.4. Each tube bundle comprises 6 parallel tubes. Each tube of each tube bundle is connected to the absorption plate 35 of the absorber module 30.

Viewed from the top view, the distance between the tubes of each individual tube bundle is so small that no warm area can form on the surface of a tube bundle. The absorption power, while traveling undulating up and down, that is, going down between the tubes, never reaches the critical point of 25% Pmax absorption power, which would define a warm region. However, the absorption power between the individual tube bundles 34.1 and 34.2 drops so much that a warm area forms there. Just above this area is located in the area of the PV module, a non-transparent area 22. In this area Between the two tube bundles, two solar cell strips are glued in strips under the glass pane of the PV module 20. Furthermore, the areas to the right of the right-hand tube bundle and to the left of the left-hand tube bundle are each equipped with a strip of solar cells at the level of the PV module 20.
