Definitions

  • the invention relates to a solar system for generating solar power with a plurality of solar modules having a holding frame and solar cells.
  • solar systems are set up on the roof of a house or on an open area.
  • a row-wise arrangement of the solar modules is known, in particular on open spaces, the solar modules being oriented largely to the south at an angle that is as favorable as possible in order to subject the solar modules to as much solar radiation as possible.
  • solar systems used mainly in southern countries are known in which the solar modules are aligned as well as possible with the sun during a day by means of a movable and controlled supporting structure.
  • the technical effort is greater here, but the power yield is maximum due to the optimal alignment of the solar modules throughout the day.
  • an arrangement of solar modules which has a supporting structure in the form of a pointed roof, the solar modules being arranged with an orientation on the one hand to the west and on the other hand to the east.
  • the individual solar modules are not used optimally due to the lack of south orientation, but the combination of west and east orientation results in a higher power yield per unit area of the subsurface.
  • the individual solar modules are carried by a supporting structure which is formed from a self-supporting rod, so that the solar modules only have to be placed and fixed on the supporting structure.
  • the area arranged under the solar modules is acted upon by the supporting structure through individual supports in such a way that the area can no longer be used.
  • the present invention is therefore based on the technical problem of specifying a solar system for generating solar power with an improved use of the surface area.
  • a solar system with at least three solar modules having a holding frame and solar cells, preferably with a plurality of solar modules, with at least two base elements, with connecting elements for connecting the holding frames to one another and with support elements for connecting the holding frame to one of the Base elements, the holding frames each having two first side edges running parallel to the base elements and at least two further second side edges, the connecting elements each connecting two first side edges of at least two pairs of holding frames to one another at a predetermined angle of less than 180 ° and at least three Holding frames are connected to one another along the first side edges and form a curved solar module section.
  • the solar modules are built up in sections to form a self-supporting structure, so that no further supports are required between the two external solar modules.
  • the construction therefore resembles a classic archway or window arch construction made of stones.
  • a curved solar module section can be formed with three solar modules.
  • the individual solar module sections preferably have six to ten, in particular eight solar modules, so that on the one hand the span is greater than with three modules and the angles between the individual solar modules are greater and closer to 180 °. In the case of a solar module section with six to 10 solar modules, there is a larger chip width and larger angles between the holding frames.
  • the angle between the holding frame or the solar modules depends on the number of solar modules used. In the case of a solar module section with only three solar modules, the angle is preferably approximately 130 ° to 150 °. In the case of solar module sections with 6 to 10 solar modules, the angle is preferably between 160 ° and 185 °.
  • the solar module sections can span a distance of five to ten meters in a vault-like manner.
  • the height of the solar module sections can be in the range from 1 to 3.5 meters, preferably 2 meters. The limits are not fundamentally limited, but rather by the stability of the individual solar modules and their connections.
  • the outer solar modules which are connected on a first side edge to the support elements on the base elements, are preferably aligned in such a way that the central plane of the solar module runs in the direction of the base element. In this way, a favorable introduction of force to the base element is achieved.
  • a solar module is understood to be a known solar module in which a plurality of solar cells are arranged in an outer holding frame.
  • the solar cells can be monofacial and convert sunlight into electrical energy from only one side.
  • the solar cells can, however, also have a bifacial design and convert light incident from both sides of the solar module into electrical energy. Sunlight that passes through the solar module can thus also be used to generate electricity after being reflected on the ground.
  • the shape of the solar modules is usually rectangular and has two long first side edges and two short second side edges. In contrast, the solar modules can also have a different shape, but in the present case the formation of parallel first side edges is necessary.
  • the solar modules can also have two short first side edges and two long second side edges, or the solar modules can be square with first side edges and second side edges of the same length.
  • the invention is described below with the preferred embodiment with two long first side edges and two short second side edges.
  • the solar modules are electrically or electronically connected to one another in a known manner and the power generated is transmitted to a transformer station in a conventional manner and with known means, without this being important in the construction of the solar systems.
  • the basic elements described are usually designed to be connected to a substrate. As a result, good stability is achieved, especially when the subsurface is not paved, for example if it is an open field.
  • the base elements can also be arranged on a solid base, in which case no fixing to the base is required, and a construction that can be moved on the base is even possible.
  • the connecting elements are designed as profile frames made of metal, in particular aluminum or an aluminum alloy, or hard plastic.
  • the connecting elements can therefore be produced and made available in large quantities at low cost.
  • the self-supporting construction of the interconnected solar modules is a vault-like structure. Therefore, the solar system described spans a free one Area without significantly restricting its use.
  • One possible application is a free field, the surface of which can be ordered with an existing solar system.
  • the solar system provides shade, plants that thrive in the shade can be grown and harvested.
  • the solar system described can also be set up on a paved surface, for example in urban areas such as squares, platforms or parks. As long as the solar radiation is not significantly restricted, the solar systems described can shade areas and make them more usable for people on sunny days or even on rainy days.
  • the base elements can also be fastened on stilts in order to increase the height of the spanned space.
  • the solar system described can be used as an underlay device such as a shed or a carport.
  • the connecting elements preferably connect the holding frames of at least some of the solar modules to one another at the same angles along the row of holding frames. This results in a symmetrical structure that ensures increased stability. It is possible, in particular in the edge area, to arrange the solar modules in a planar manner, that is to say at an angle of approximately 180 °. This allows a greater height of the vault to be achieved.
  • the connecting elements are designed like rails and have a length not greater than the length of the first side edges. In this way, the first side edges of adjacent solar modules can possibly even be connected to one another along the entire length.
  • At least two solar module sections are connected to one another at least in sections along second sides of holding frames, preferably only at the corners of holding frame. This creates a curved roof that can be extended to a long roof similar to a greenhouse by using a large number of solar module sections. If not only the first side edges but also the second side edges are connected to one another, for example by means of rail-shaped connecting elements, a construction that is largely closed at the top can be achieved, which reduces or even prevents the ingress of air and moisture.
  • the length of such a construction of a multiplicity of solar module sections in the direction of the second side edges is in principle not restricted and depends on the length of the subsurface. Thus, for example, lengths of over 100 meters or even 500 meters or more are possible.
  • a further advantageous embodiment of the described arrangement consists in that the support elements are designed to be displaceable with respect to the base elements.
  • a construction can be selected in which the support elements are displaceable with respect to the base elements, that is to say can slide or roll.
  • a subsurface can only be partially shaded by the solar system, while another part remains free.
  • the base elements are preferably designed as pipes, in particular as concrete pipes. Other alternatives, such as concrete foundations or steel profiles or sheets rammed into the ground, can also be used, depending on the nature of the ground. Conventional building materials can thus be used economically.
  • the attachment of the support elements to the pipes or alternative foundations can then be carried out on site.
  • the base elements are suitable for carrying two support elements of two different solar module sections in a longitudinal position. This further reduces the cost of materials for the solar system.
  • the connecting elements, the support elements and / or the base elements can take on further functions, such as those required in agriculture, for example.
  • the connecting elements and / or the support elements can be provided with water pipes and water distribution systems in order to irrigate the space below the arched arrangement of the solar modules and, if necessary, to supply other substances such as fertilizers or plant or insect repellants.
  • lighting means can also be provided.
  • the base elements can, for example, also be provided with rails on which movable and possibly automated processing devices for sowing, caring for and harvesting the plants grown underneath the solar system can be guided.
  • the connecting elements, the support elements and / or the base elements can also have channels and openings for ventilation of the space below the arched solar systems.
