Definitions

  • the invention relates to a solar panel of the type that is intended chiefly for mounting for example on the roof of a house or other building.
  • the solar panel can be used singly in this connection or - as is normally the case - in conjunction with several solar panels of the same or a similar type.
  • the invention relates to a solar panel of the so-called flat type, which comprises an absorber element lying in a surrounding frame structure and applied to a heat-insulating insulation element and covered by a transparent covering sheet on the side of the solar panel facing towards the sun.
  • the absorber element is preferably, but not necessarily, of the type that is designed to be flowed through by a heat-bearing liquid, usually water, or water with an anti-freeze admixture.
  • the invention provides a solar panel comprising an absorber element, a heat-insulating insulation element placed between the absorber element and an underlayer, and a frame structure surrounding the insulation element and the absorber element.
  • the invention is characterized in particular in that said insulation element and said frame structure are integratedly formed into an essentially box-shaped, self- supporting base element having a recess for accommodating said absorber element, which base element consists in the main of a foamed plastic material.
  • the solar panel also comprises a transparent covering sheet placed over said absorber element.
  • the base element has fastening organs for the absorber element.
  • the fastening organs consist of through holes in the base element, which holes are adapted to interact by press fit with pipe joints located on the absorber element.
  • the base element has a support surface for contact with the covering sheet, which support surface is located on a continuous support vane which projects from the bottom surface of the recess on the base element.
  • the recess in the base element preferably accommodates the absorber element in its entirety, including the pipe joints located on the absorber element.
  • the base element is also clad with a surface layer of a plastic material, the density of which exceeds the density of said foamed plastic material.
  • the base element has a recess for accommodating the transparent covering sheet, in which recess support surfaces facing upwards are executed for contact with the covering sheet.
  • the foamed plastic material has a density in the range of 20-80 kg/m 3 , preferably 40-60 kg/m 3 , and also preferably consists of polypropylene foam.
  • a range of other plastic foam materials can be used alternatively, such as polyethylene, polyurethane, polystyrene etc., which will be described in greater detail below.
  • the invention offers a very advantageous solar panel of a considerably lower weight than previously known solar panels. Due to the integrated base element in foamed plastic material, the number of constituent parts in the solar panel is also reduced, which together with the relatively low material cost of the plastic foam material signifies a considerably lower production cost. The low weight also makes it possible to fit the solar element smoothly on a house roof, for example, without the help of an expensive hoisting crane.
  • Fig. 1 shows an exploded outline in perspective of a solar panel according to a first embodiment of the invention
  • Fig. 2 shows the solar panel in Fig. 1 , but in the assembled state
  • Fig. 3 shows a top view of the integrated base element in foamed plastic material
  • Fig. 4 shows a view in section of the long side of the base element, taken along the line B-B in Fig. 3
  • Fig. 5 shows a side view of one long side of the base element
  • Fig. 6 shows a view in section of the short side of the base element, taken along the line F-F in Fig. 5
  • Fig. 7 shows a view in section of the central part of the base element, taken along the line A-A in Fig. 3
  • Fig. 8 shows finally an alternative embodiment of the invention, in which the base element is clad with a surface layer of plastic material.
  • the reference number 1 generally describes a solar panel according to the invention.
  • the solar panel 1 is constructed from an absorber element 2, a heat-insulating insulation element 3 placed between the absorber element 2 and an underlayer (not shown), and a frame structure 4 surrounding the insulation element 3 and absorber element 2.
  • the frame structure 4 is formed integratedly according to the invention together with the insulation element 3 to give a box-shaped, self-supporting base element 5.
  • the solar panel is sealed in the example shown by a transparent covering sheet 6, which is preferably manufactured from polycarbonate plastic.
  • the base element 5 consists in its entirety in the example shown of a foamed plastic material with closed pores.
  • the base element 5 is preferably executed in this connection in polypropylene foam with a density in the range of 20-80 kg/m 3 , preferably 40-60 kg/m 3 , with good heat-insulating properties.
  • Other foamed plastic materials can also be used alternatively, however, such as polyethylene, polyurethane or polystyrene, for example.
  • the foamed plastic material suitably also contains a UV stabilizer, such as carbon black, to protect against ultra-violet radiation.
  • the fact that the frame structure 4 is formed integratedly with the insulation element 3 means that the frame structure 4 in itself acts as heat insulation, and thus does not need to be lined with separate insulating material, as is the case with many previously known solar panels.
  • the integrated base element also has an essentially rectangular recess 7 to accommodate the absorber element 2.
  • the absorber element 2 in the embodiment shown is of the type which is designed to be flowed through by a heat-bearing liquid, normally water or water with an anti-freeze admixture.
  • the absorber element 2 according to the example shown comprises two absorber bodies 8, 9 arranged beside one another and incoming or outgoing pipe joints 10.
  • the absorber bodies 8, 9 contain in a conventional manner a plurality of liquid channels (not shown).
  • the absorber bodies 8, 9 are executed in polypropylene plastic, but alternatively other plastic materials with similar properties can be used.
  • the solar panel 1 according to the invention is shown in the assembled state, it being evident that the recess 7 in the base element 5 accommodates the absorber element 2 in its entirety, i.e. including the pipe joints 10, which on conventional solar panels (not shown) normally run outside the surrounding frame structure 4.
  • An advantage is hereby achieved in group mounting of the finished solar panels 1 , for example on a house roof (not shown).
  • a support surface 11 for contact with a covering sheet 2 is located on a continuous support vane 12 extending centrally over the base element 5, which vane projects from the bottom surface 13 of the recess 7 on the base element 5.
  • the two absorber bodies 8, 9 are placed on each side of this support vane 12.
  • the integratedly formed base element 5 also has fastening organs 17 for the absorber element 2, which consist of through holes 18 in the base element 5.
  • the through holes 18 are adapted to interact by press fit with pipe joints 10 located on the absorber element 2. Following fitting, the absorber element 2 is hereby fixed without play in the base element 5.
  • the extension of the holes 18 is plainly evident in Figs. 4, 5 and 6.
  • the foamed plastic material in the elastic properties of the base element 5 is well-suited in the context for achieving a suitably "squeezing" press fit, which due to the properties of the plastic foam continues to give a certain flexibility in the case e.g. of bending stresses which arise on transportation or erection of the solar panel 1.
  • Fig. 8 shows an alternative embodiment of the integratedly formed base element 5, in which the base element 5 is clad with a surface layer 19 of a plastic material, the density of which exceeds the density of said foamed plastic material.
  • the plastic material in the surface layer 19 can consist here for example of polyethylene, polystyrene or any other plastic suitable for the purpose.
  • the foamed plastic material can here be said to form a core 20 in the base element 5.
  • the surface layer 19 gives the base element 5 increased protection against undesirable water penetration and other external damage.
  • the surface layer 19 is relatively thick, an advantageous production method consisting of rotation casting.
  • the material in both the surface layer 19 and the core 20 consists suitably in this case of polyethylene.
  • the surface layer 19 can be considerably thinner (not shown) and consist in practice of a thin, protective plastic film.
  • the solar panel 1 does not necessarily have to be flat as shown in the drawings, but an alternative embodiment can also consist of a curved solar panel 1 (not shown).
