Description

Integrated structural element for concentrating photovoltaic module
The present invention relates to solar plants for the production of electrical energy by photovoltaic cells, particularly concentration cells.
Although the technology of the photovoltaic concentration plants is based upon well-established concepts, it has not been confirmed by the market, with the only exception of the United States. In recent years, however, the world has been showing an interest for photovoltaic concentration cells following up the interesting efficiency levels provided by small-size cells.
It should be appreciated that a photovoltaic concentration module is a device able to concentrate the light hitting the active components of the solar, generally small-size cells with high efficiency by the use of optical system. Such module is an assembled device including optical systems, solar cells, circuitry, and is able to protect cells and sensitive elements from bad weather conditions as well as to ensure the alignment stability of the optical system and the solar cells.
The photovoltaic concentration modules essentially consists of three main components: lenses, cells, and carrying structure. The lenses concentrate the solar light incident to their surface on a focus. The main features of the lenses have to be: - good light transmission all over the solar spectrum, greater than 80%;
- weatherability, if not otherwise protected;
- focusing capability and then low aberration. The photovoltaic cells are the active element of the module. They convert directly the light energy concentrated on themselves by the lenses into electrical energy. For such applications they have a size of the order of one square centimetre. The successful keystone of such a concentration module is the conversion efficiency of the cells included therein. Silicon cells with an efficiency greater than 24% are presently known. The carrying structure of the photovoltaic module is the structural element on which lenses, photovoltaic cells, any protection diodes of the cells, electrical conductors, and heat dissipators are assembled. As already partly mentioned, such structure has a number of functions. First of all it should: protect the electrical circuit and the cells from atmospheric influences; hold then the maximum temperature of the cells to acceptable values by means of suitable heat dissipators; provide an electrical insulation of the active electrical circuit from the outside; ensure a correct mutual position of the optics and the cells under several operating conditions; and further be light as it is mounted on a mobile structure following the sun in its typical operation; have, at last, low cost. In order to perform these functions, structures made by metal elements have been hitherto used. The most commonly used materials are aluminium for its light weight, and steel sheet for it low cost. The carrying structures of the presently known photovoltaic modules are usually made by manufacturing a more or less great deal of components by machine tools and then assembling the same to attain the finished product. A first drawback of these construction technologies is given by the high production and automation/mechanization cost.
A further drawback of the presently known technical solutions is that the coefficients of thermal expansion of the components are not negligible and fix limits to the maximum size of the modules.
At last, another drawback of the known technique is given by that the metal structure requires a good insulation with respect to 'the active circuit to keep the insulation degree required by regulations. According to the present invention, the above- mentioned problems are overcome by designing a carrying structure of die-casting fibreglass- reinforced plastic. With fibreglass-reinforced plastic it is intended one of the many types of plastic in which a fibreglass increasing its mechanical properties is immersed. The fibreglass-reinforced plastic has a light weight, is resistant to the atmospheric influences and acts as a good electrical insulator. The fibreglass filler makes the plastic very rigid and gives it a little thermal coefficient of expansion. At last, the use of a die with well-finished surfaces produces pieces with a surface finishing that does not require any additional finishing treatment. According to the invention, this has been accomplished by providing a carrying structure consisting of a monolithic basic element that allows the concentration of the solar radiation to be used for the generation of photovoltaic energy by integrated refractive optics.
A better understanding of the invention will result from the following description with reference to the accompanying drawings that show a preferred embodiment thereof only by way of a not limiting example. In the drawings:
Figure 1 is a picture of the interior of the carrying structure of a photovoltaic concentration module according to the invention;
Figure 2 shows a detail of fig. 1;
Figures 3 is a section view showing a detail of the fastening system of a refractive lens on the carrying structure of fig. 1;
Figure 4 shows a detail relative to the fastening of the construction component to a mobile structure able to follow the sun; Figure 5 is a top three-dimensional view showing the interior of the module without lenses;
Figure 6 is a bottom three-dimensional view showing the outside of the bottom of the module on which the heat dissipators of the photovoltaic cells are disposed;
Figure 7, similar to the preceding one, is a cross section of the module on which the refractive lenses are disposed;
Figures 9A and 9B are a three-dimensional view and an exploded three-dimensional view of the assembling of the photovoltaic cells to the substrate of aluminium nitride as .supplied by the manufacturer, respectively; and
Figure 10 show a detail of the assembling of a cell to the respective dissipator, and the circuitry of the cells.
With reference to figures 1 to 7, the carrying structure of the photovoltaic module includes a main body 1 consisting of a rigid moulded carrying container the inside bottom of which has housings to receive leads 2 of the active circuitry. The bottom of such carrying structure has holes in which photovoltaic cells 3 already glued to respective heat dissipators 4 are positioned. The dissipator are fastened by screws engaging threaded. housings moulded in the bottom. Additionally, housings for 0-rings preventing the water from seeping through the holes into the module are moulded in the bottom too.
Truncated cones 5 with vertexes directed upwards project from the bottom of the carrying container
(fig. 2) and, together with the side walls, support refractive lenses 6 which are glued side by side to one another like a parquet and are kept at the right focal length from cells 3.
Such lenses 6 can also be formed by Fresnel lenses or other prismatic optical devices. The threaded housing of the central fastening screw of the parquet able to collimate the focuses of lenses 6 with respective underlying cells 3 is moulded in the lower (upper) base of at least one truncated cone 5, preferably at the centre of carrying container 1. Such carrying container has an edge 7 also of fibreglass-reinforced plastic provided with recesses in its lower portion and allowing the "parquet" of lenses to be fastened by steel springs 8, preferably in a quite similar way as the well-known open frames for paintings. A housing for lens parquet sealing gasket 9 is moulded in the upper portion of the edge to prevent a water seepage (fig. 3) .
Stiffening ribs 10 are formed on the side walls and the inside and/or outside bottom of the carrying structure to restrict the deformations due essentially to the wind within a few tenths of millimetre. Finally, mounting holes for the module to be connected to a mobile structure of the known type moving the photovoltaic module to keep it directed to the sun are formed by moulding in the outside bottom of the body of the carrying container. Such connection is carried out by bolts according to the diagram of fig. 4. It should be inferred from the foregoing that all disclosed details of the carrying structure that were manufactured one by one according to the prior art by means of tool machines are now moulded simultaneously according to the invention.
On trial, a prototype of the module consisting of the previously disclosed carrying structure of fibreglass- reinforced plastic was subjected to test in wind tunnel to simulate the behaviour under operating conditions and to evaluate any deformations. The result was that also under strong wind (e.g. 60 km/h) the deformations were very small, of the order of tenths of millimetre, such as to keep the centring variation of the photovoltaic cells with respect to the relative concentration optics within acceptable limits. The module was then fastened to a mobile structure following the sun. The measured conversion efficiency, little greater than 16%, showed the optimum optical centring of the lenses to the cells due to the stability and precision of the structure of fibreglass-reinforced plastic according to the present invention. In a variation of the finding shown in figures 8 to 10 the carrying structure of the module (fig. 8) consists of a preferably rectangular container 1 similar to a tub also provided with bottom opening to allow solar cells 3 to be directly fastened to respective dissipators 4 of aluminium, thus helping the heat dissipation.
In this case, a plurality of pyramidal, instead of conical, elements 5 project from the bottom with the function of spacers, supports for concentration optics 6 as well as parquet fastening members by upper end screws.
Figure 8 shows from the top to the bottom: glass or other (optional) covering, parquet of lenses β, (schematic) 0-rings. Springs are arranged about them like only one component for each side. Actually, the springs can be more than one for each side. Dissipators 4 are mechanically secured to the bottom of the module and the sealing is ensured by 0-rings. Photovoltaic cells 3 (figs. 9A and 9B) are of the commercial type provided by the manufacturer and already assembled on suitable bases B of boron nitride having high thermal conductivity and electrical insulation and provided with copper contacts C, the positive polarity of which is designated by a bevel. The cells are further protected by a cerium glass V. Already assembled cells 3 are secured to dissipators 4 preferably by an epoxy resin able to ensure an intimate thermal contact between cell/base and dissipator. In the example shown, the cells are electrically connected by copper bars of 10 mm2 which are tin-plated to avoid corrosion and connected by suitable springs to ensure the electrical continuity between the output of the cells and the connecting leads (fig. 10) .
Finally, it is preferable to insert by-bass diodes into each cell for the protection against any hot spot. Concentration lenses 6 are assembled by gluing then by acrylic glue to a support plane. The lens parquet can be protected by a film and is secured to the module by a gasket spring.
At last, the module is provided with a vent hole SF to prevent overpressures due to temperature range and condensate as well.
It should be appreciated that the carrying structure according to the invention allows a container to be provided by a technique (moulding) that guarantees low cost for a production on an industrial basis and at the same time structural modules to be provided with high stiffness and resistance as well as with a very low thermal changeability and an optimum electrical insulation.
