  • the subject of the invention is covering or building element with solar cells fixed for the sunny sides of the buildings, which can be fixed to the sunny vertical sides of buildings, frame structures, and/or to the flat top of those and have current-generating solar cells mainly perpendicular to the direction of the incoming solar radiation.
  • the bearer of the solar cells can be an element with ability of heat-, water-, and windinsulating, as well sound-reducing capacity.
  • the covering element can be an integrated one with shell structure. In given case the (intelligent) covering of the surfaces of the buildings can be realized as well, because following automatically the direction of the incoming solar radiation can be solved as well.
  • the buildings with poor insulation covering, primarily the pre-fabricated panel buildings can be provided with effective insulation posteriorly, producing at the same time electricity in an explicitly environmentally friendly way.
  • German patent publication describes such solar cell glass tiles, suitable for roof covering, which are provided with multi-layer solar panels, with flat solar panels on the uncovered places and below them there is an air space formed, cooling the solar panel on the bottom of the tile.
  • German patent publication also makes known a glass tile with solar cell, but with this solution the glass tile is not flat, but of partly archy surface, so an extremely thin 0.05-1 micrometer amorphous silicium layer is put on it.
  • Their common drawback is, that they can be used on buildings with one-pitch-roof only.
  • Panels for insulation can be made even from waste, such as eg.: on basis of the Hungarian patent HU 184252 describing production of insulating material from reed, thatch and polyurethane foam.
  • the JP 63067788 Japanese patent publication document relates to the energy supply with solar cell covering of a small size, box-like equipment - presumably a refrigerator.

  • the Fig 1 shows the incoming solar radiation conditions in winter and summer for a solar cell according to the invention, provided with mirrors, placed in the 45-50° angle common in Hungary. It is well known, that the energy production of solar cells 3 depends greatly on the angle between the direction of incoming solar radiation 14 and the plane of the solar cell. Energy production can show a difference of even 30% in case of the same direction of incoming solar radiation 14. Resulting from this a number of small magnifying glasses are frequently used for projecting the solar rays from every direction to the solar cell 3, or the solar cell 3 is moved to the ideal direction.
  • the setting angle of free-standing solar cells is determined on basis of the weighted value, namely the angles of approach a of months bringing more energy are taken into consideration to a greater extent.
  • the weighted average angle of approach a is 50° on basis of the monthly incoming solar radiation energy and the relevant angle of approach a.
  • the plane of the covering element 1 provided with solar cell 3 to be placed on the vertical wall 7 is in Hungary generally 50° to the main plane of the covering element 1 (for simplicity's sake furthermore the denomination covering element 1 is used instead of the denomination of covering- or building element).
  • the Fig 2 shows the incoming solar radiation conditions in winter and summer for a solar cell placed in 30-35° angle according to the invention, provided with mirrors 42.
  • the plane of the solar cell 3 is determined in such a way, that the reflected sun radiation was taken into consideration too. This way it can be achieved, that the direction of incoming solar radiation 14 can be well utilized between 19.49 degrees (December) T winter and 66.4 degrees (June) Ny summer, and the winter energy acquisition can even be multiplied.
  • the solar cell 3 combined with mirror 42 offers solution to the utilization of the building surfaces of not entirely southern orientation, as orientation of existing buildings can not be changed. This case also good results can be achieved by surfaces with mirrors 42 next to the surface provided with solar cell 3, as in such case at least one part of the solar radiation approaching in small angle, particularly in the mornings or in the evenings is projected onto the solar cell 3 by the mirror 42.
  • the Fig 3 shows the section of the covering element 1 made of thermal insulating material, according to the invention, with a bolster 8 sleeper fastening fixing.
  • the most important part of the covering element 1 is the thermal insulator panel 2, and the solar cell 3 fixed on its surface towards the direction of the Sun, as well as the mirror 42 placed adjacently on the shady part.
  • the thermal insulator panel 2 is a formed polyurethane foam material in this figure, which has a compact part of a certain layer thickness, and several planes protruding saw-tooth-like.
  • each covering element 1 can be connected to an electric collector system (see also the Fig 5).
  • a plastic covering 15 In case of our example, it is a transparent polypropylene material deep-drawn to a shape known in application of packaging of various equipment, that can be snapped on to the thermal insulator panel 2. On top the plastic covering 15 leans downward slantwise from the wall 7 and its rim penetrates below the edge of the thermal insulator panel 2. The other end is shorter, so this forming prevents the rain to get behind the covering element 1.
  • the solar cells 3 according to the invention are placed below one another in such a way, that the external edge 24 of the surface supporting the solar cell 3, and the internal edge 25 of the solar cell 3 below it fall into a projection plane 26, which is perpendicular to the plane of the solar cell 3, or deflects from it maximum +/- 20 mm.
  • Any solar cell 3 is suitable for the purpose of the invention.
  • the maximum achievable efficiency of the three basic solar cells 3 of the known solar cells 3 is as follows:
  • Multicrystalline solar cell 13 - 15%
  • Amorphous solar cell 5 - 8%
  • the covering element 1 can be fastened to the wall 7 with any of the known technologies.
  • the solar cell 3 should be preferably fixed with this realization to the thermal insulator panel 2 by sticking.
  • the backwall of the thermal insulator panel 2 with this realization is of plane surface, usually bolsters 8 are used for the fastening.
  • the bolsters 8 should be provided with header 9, which are preferably thin, insulated copper sheet strips, where the poles of the solar cells 3 of the covering element 1 can be connected with the help of screws 10.
  • each covering element 1 needs at least two such screws 10. In case of covering elements 1 of bigger size, additional screws 10 might be needed, but these are not connected to the electric header 9.
  • the Fig 4 shows another embodiment of the fixing of the covering element 1 according to the invention.
  • the backside of the thermal insulator panel 2 is of staged finish. It results in the simplicity of hooking up on the bolster 8 with properly slanting upper edge, so fixing is easier.
  • the upper edge of the thermal insulator panel 2 rises slanting towards the wall 7 of the building in order to avoid rain getting between the thermal insulator panel 2 and the wall 7. Resulting from the same reason the lower edge of the upward next covering element 1 is parallel with it, so the covering elements 1 above one another are in overlapping.
  • the size of the surface supporting the solar cell 3 is primarily determined by aesthetic considerations. There are a lot of buildings (historic monuments) where it is not possible to alter the outside, so here the possible smallest protrusion is recommended, so solar cells 3 stuck to a carrier surface of 15 mm width should be applied.
  • the Fig 5 shows the electric connection of the covering element according to the invention in partial section.
