Definitions

  • the invention relates to a support structure for photovoltaic modules (PV modules).
  • PV modules photovoltaic modules
  • the yield of a PV module essentially depends on the angle of solar radiation. It is true that in vertical sunlight, the yield of the PV module is greatest and decreases with increasing angle.
  • One problem is that the suns migrate in the course of a day and the angle of incidence changes constantly when the PV module is stationary. The angle of incidence is therefore rarely optimal.
  • CONFIRMATION COPY On flat roofs or low pitched or pitched roofs mainly supporting structures are used, in which the PV modules are arranged on stands that have a geographic location adapted elevation angle. In these stands, it is relatively easy to make the elevation angle of the stand variable, so that at least the elevation angle can be adapted to the changed position of the sun. This can also be done automatically. Although the yield can be increased thereby, a greater gain in yield would be possible by an azimuthal tracking, since the azimuth angle, which the sun passes over during the day, is greater than the migrated elevation angle.
  • the object of the invention is therefore to provide a support structure for a photovoltaic system, which is suitable for private purposes and allows improved energy yield.
  • the holder has at least two fixed, circular arc-shaped guide rails, which are aligned parallel to the mounting plane, wherein the curvature of at least one guide rail against the curvature of the other guide rail is aligned, that the tracking unit has a self-supporting frame which is guided in the guide rails, wherein the frame is deformable parallelogram, whereby the azimuth angle of the stator is variable and that the stator is fixed to the frame.
  • the Daily course of the sun are followed at least in a partial area, whereby the duration of the vertical as possible vertical radiation is extended. This automatically increases the yield of the PV module.
  • the azimuthal tracking is made possible by a scissor-type construction of the frame.
  • the frame has several points which are movably guided in the circular guide rails. By moving along the guide rails, the frame is deformed in a parallelogram shape.
  • At least one guide rail has a motor drive for automatic tracking of the tracking unit.
  • At least one guide rail preferably has a toothed rack into which engages a toothed wheel which is driven by an electric motor and the other guide rails have guide rollers for guiding the frame.
  • the electric motor has a control with a light sensor, via which the optimum position of the PV modules can be determined to the sun and this position is automatically controlled.
  • the stands are in a fixed elevation angle for mounting.
  • the stands are movably coupled to the frame, so that their elevation angle changes during a movement of the frame.

  • Fig. 5 is a plan view of a support structure according to the invention with dashed lines shown twisted position of the tracking unit.
  • Fig. 1 shows an exemplary embodiment of the invention.
  • the support structure 1 shown has a holder 2 and a tracking unit 3, on which three stands 4 for receiving photovoltaic modules (PV modules) 5 are attached. Both framed and unframed PV modules can be used.
  • PV modules photovoltaic modules
  • the stands 4 have a fixed elevation angle ⁇ , which is preferably selected depending on the geographical location of the site.
  • one or more PV modules 5 can be arranged on each stand 4, depending on the size of the uprights and the modules.
  • essentially U-shaped attachments 6 are provided, wherein the two U-legs have different lengths depending on the elevation angle ⁇ (FIG. 2).
  • each stand 4 has three such fasteners 6.
  • the number can be varied as desired with the size of the stand 4.
  • the uprights 4 can also be fastened differently to the tracking unit 3.
  • Framed PV modules can be attached directly to the U-shaped mountings on the tracking unit, while frameless PV modules require additional support on the stands.
  • the support structure 1 according to the invention is not limited to three stands 4. Rather, the number of stands is almost arbitrary. In Fig. 3 by way of example a support structure 1 is shown with only one stand 4, which substantially corresponds to the support structure of FIG.
  • the essential features of the invention can be seen in FIG.
  • the embodiment shown in the example also has three PV module stand 4, wherein here too the number is almost arbitrary.
  • the fixed bracket 2 has a total of six circular curved guide rails 7, which are firmly connected to a base, such as a roof or an intermediate structure.
  • the curvature of the guide rails 7 extends parallel to the mounting plane.
  • the guide rails 7 are each arranged in pairs opposite one another, wherein the curvature of the rails 7 of a pair is oriented in opposite directions.
  • the tracking unit 3 has a substantially rectangular frame 9, which is formed in the example by aluminum profiles.
  • the distance of the paired guide rails 7 is determined by the width of the frame 9.
  • the pairs themselves are each arranged identically offset along the length of the frame 9.
  • the frame 9 has two longitudinal struts 10 and six transverse struts 11, wherein the longitudinal and two transverse struts define the edge of the frame 9.
  • the remaining cross struts are arranged equidistantly between the two edge cross struts 11 in parallel, wherein for each guide rail pair each two adjacent cross struts are necessary, which are divided into first and second cross struts.
  • the lowermost transverse strut 11 is a first transverse strut. Upwards follow alternately a second and again a first cross strut.
  • the guide rails 7 on the right side of the image are now arranged so that each of the beginning is tangent to the junction 14 of a first cross member 11 with the right longitudinal strut 10.

  • the opposite guide rails 7 on the left side of the image are each arranged so that each of the beginning tangent to the junction 14 of a second transverse strut, 11 with the left longitudinal strut 10 is located.
  • 14 guide rollers are arranged in each case at the connection points, which engage in the guide rails 7.
  • the individual transverse and longitudinal struts are each rotatably connected to each other by bolts or screws. Furthermore, the transverse struts 10 are rotatably mounted on the central longitudinal strut 8 of the holder 2, wherein the respective attachment points 15 form the axis of rotation for the tracking unit 3.

Likewise, if the distance between the stands 4 is too small, mutual shading of the PV modules 5 takes place, which leads to a lower yield.
  • the support structure 1 according to the invention is very simple and has compared to a fixed construction only little extra weight, so that an installation on a private house or a residential building is easily possible. Another advantage is that, due to the rotation, the support structure does not require any width in the width and only little additional space in the length.

  • the average yield of a solar system with elevated PV modules can be increased on average by up to 35% over a single day.
  • a preferred embodiment of the invention provides that the stand are attached to the frame via a rotatable suspension, which allows a change in the elevation angle ß.
  • the upper edge of a stand is connected via a rotatably mounted strut with a longitudinal strut of the frame.
  • the distance between the upper stand edge and the longitudinal strut changes, which automatically changes the elevation angle ß of the stand.
  • the support structure according to the invention can be composed in all versions of lightweight aluminum profiles, so that the total weight is very low and thus a mounting on a flat or pitched roof of a residential building or a garage for private purposes is possible. Due to the simple construction, the invention is only slightly more expensive than a fixed stator mount for PV modules, the additional costs are quickly amortized by the significantly increased yield.
