Abstract

The invention relates to a device for utilising solar energy with solar cells which have a supporting structure (11) and are electrically connected to one another and which also have an external connection for removing the electrical energy. A plurality of solar cells are parts of an edgeless solar cell laminate in which the solar cells are encapsulated side by side in a sheet-type or panel-type carrier. At least one side of the laminate which faces the sunlight is flat and transparent to light. The solar cell laminate lies in the supporting structure (11), which consists of two covering layers (8, 9) and a supporting foam layer (7) and which also forms a circumferential recessed edge. At the edge, the laminate is flush with the upper side of the supporting structure. The edge is of corrugated construction between two parallel edge sections in order to support the solar cell laminate on more highly placed sections and, together with the lower-lying sections, channels (10) serve to convey a coolant and receive energy-conveying means. <IMAGE>

Name and Address of Applicant: Schottel-Werft Josef Becker 5401 Spay Bundesrepublik FEDERAL REPUBLIC OF GERMANY GmbH Co. KG Actual Inventor(s): Address for Service: Inventi n Title: Andreas Naujeck and Stephan Schneider Spruson Ferguson, Patent Attorneys Level 33 St Martins Tower, 31 Market Street Sydney, New South Wales, 2000, Australia Apparatus for the Utilization of Solar Energy with Solar Cells The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845/3 I~I9 APPARATUS FOR THE UTILIZATION OF SOLAR ENERGY WITH SOLAR CELLS The invention relates to an apparatus for utilizing the energy of the sun, and more particularly to an arrangement of solar cells on a supporting structure.
It is an object of the invention to provide a particularly appropriate refinement of the arrangement of solar cells on a supporting structure, which is to be highly permanent and extremely light and which preferably can be integrated into the upper deck of a water vessel. The arrangement of the solar cells to obtain I0 energy should be accomplished in as simple a manner as possible, in order to keep the price of the arrangement within acceptable limits. The arrangement should be accomplished with few components, which have little tendency to break down. As a further main objective, the arrangement of solar cells should be of as low a weight as possible, so that the arrangement can be used universally beyond the particular application set forth herein.
In order to come as close as possible to accomplishing the objective of the invention, the invention provides for the use of frameless, enclosed solar cells, so-called solar laminates, on a supporting structure preferably capable of accommodating a plurality of such solar laminates. Moreover, the invention involves thG fixation of this plurality of solar laminates on the upper side of the supporting structure, such as by means of a transparent film, which is stretched smoothly over the solar laminates and fastened to the edges of the supporting structure.
The invention is explained in greater detail by means of the drawings, in which: Figure 1 is a side view of a ship, which is equipped according to the invention, Figure 2 is a perspective view of a solar laminate, as used according to the invention, and Figure 3 is a cross-sectional view, through one of the two roof parts of the ship of Fig. 1, of an arrangement of solar cells which, according to the invention, are covered with solar laminates.
The upper sides of the foredeck 1 and of the roof 2 of an appropriately constructed ship or boat 3 are covered with enclosed solar cells. These solar cells are constructed as solar laminates, that is, as solar modules without an encompassing frame.
Several solar cells 4 are enclosed in a particular pattern, preferably in one row, but possibly in several rows, which cross one another or are disposed next to one another or behind one another in a transparent film strip 5, or in an appropriate thin panel, that is, they are enclosed by this film or panel. The film strip 5, or the panel, which encloses the solar cells 4, can consist of two superimposed individual strips or panels, which are connected with one another two-dimensionally and between which the solar cells 4 are held. The strip or plate, which in the installed state faces the radiation of the sun, is transparent, while the other strip or the other plate can be of the same material or 3 optionally of a different, possibly opaque, material. The solar cells of such a "solar laminate" 4, 5 are connected electrically with one another and have a common current discharge 6. Usually, such a solar laminate is surrounded by a trimming ledge. However, frameless laminates, that is, laminates without a trimming ledge, are also used in conjunction with the invention. A plurality of such solar laminates are disposed in groups of rows and connected electrically with one another on the roof as well as on the foredeck.
3J The foredeck 1 and/or the roof 2 may be constructed as the supporting structure, which accommodates the enclosed solar cells. The roof or foredeck is of a so-called sandwich construction. The upper and lower covering panels, fiber mats, of this sandwich construction are spaced from one each other by a rigid foam and are reinforced with respect to each other by the rigid foam connected over the whole of its surfaces with the upper and lower covering panel.
According to the invention, the prepared rigid foam 7, which is appropriately contoured, preferably by cutting, is placed between the two mats 8, 9. The rigid foam has through holes which extend between its two surfaces perpendicularly to the plane of the mats. A synthetic resin is applied in the flowable state on the external side of one mat and a vacuum is applied on the external side of the other mat, so that the synthetic resin is aspirated through the first-mentioned mat, the through holes 10 and the second-mentioned mat. As a result, on solidifying, the 4 synthetic resin forms a composite from the two mats 8, 9 and the rigid foam 7 with extremely smooth solid surfaces. Sandwich constructions, so produced, are known and therefore need not be explained in greater detail. The upper covering panel of the sandwich construction is not flat, but has an undulating profile in order to provide both support and back ventilation of the solar cells. At the same time, the channels 11 (wave troughs) formed by the profiling serve to accommodate the electrical installation and cabling. Preferably, the wave troughs taper toward the inside.
Due to the profiling of the upper covering plate or mat, vary high strength is achieved in the longitudinal direction, strength is attained in the transverse direction due to the joining of the upper and lower covering panels or mats 8, 9 with the interposed rigid foam 7. The construction of the supporting body tor accommodating the enclosed solar cells 4, 5 is self-supporting and requires no supporting construction.
The supporting body with the lower covering panel 9 and the profiled upper covering panel 8, as well as the interposed rigid foam are manufactured in one step, so that an economic continuous production is possible.
Each of the solar cell laminates rests at its perimeter on the recessed edge 12 of the supporting body. The recess corresponds to the thickness of the solar cell laminates, so that the solar cell laminates and the supporting body surrounding these lie in a horizontal plane, which, if necessary, is slightly arched.
The enclosed solar cells are fixed in position with a film 13, which is passed smoothly, without bubbles and folds and appropriately stretched over the solar laminates and the edges of the supporting body and is glued on with a water-soluble adhesive.
An appropriately dimensioned film, which may be assembled from individual sheets, can fix in position all of the solar cell laminates of the foredeck or roof with respect to the supporting body, or the solar cell laminates can be combined into several groups, the solar cell laminates of each group being fixed in position by a film. The number of solar cells combined in a laminate 4, 5 depends on the circumstances. Under some circumstances, a solar cell laminate may also enclose only one cell.
The film to be used is a conventional commercial film of high strength and high transparency, and is extremely resistant to UV light and scratch-resistant. Before it is applied, the film is coated on one side with a water-soluble adhesive. If the film is completely free of bubbles and mounted flat on the corresponding solar laminates by adhesion, there will be no losses due to reflections and the losses, as a whole, will be so small, that the efficiency of the solar cell laminates is adversely affected by the film to the least possible extent, if at all. Before the film is applied, the parts coming into contact with it are moistened, so that the adhesive becomes effective.
Overall, the invention is concerned with an arrangement which consists of a few, operationally reliable and inexpensive parts, which can be assembled with little effort, and which is operationally reliable over a long period. Should a solar cell laminate become defective, it can be repaired or exchanged. Occasionally, it is also possible to make such a repair or exchange by only partially removing the film. After that, the arrangement can be made again in an equally simple manner. The film is believed to be the optimum, but not the only means, for preventing the laminates from lifting upwards off the supporting structure.
In order to avoid distortions and to compensate for possible dimensional deviations, sponge rubber strips 14 and the like are placed between the solar laminates and the supporting structure. Moreover, these sponge rubber strips, especially those between the solar cell laminates and the edge of the supporting structure, prevent the penetration of moisture between the solar lafminates and the supporting structure. For this purpose, the gaps are also filled with a permanently elastic sealing material such as a silicone rubber.
The foamed supporting body 7 may be in one or several pieces.
