Definitions

  • Solar photovoltaic modules comprising solar cells or solar panels use light energy (photons) from the sun to generate electricity.
  • the solar panels usually combined in arrays, must be properly oriented with respect to the sun to be used efficiently.
  • Such solar panel arrays may be mounted on single poles.
  • the wind effects limit the number of solar panels installed on each pole (to about 30 panels) and the strength requirements for the poles is significant and limiting.
  • the cost of underground concrete footing and foundations and their size for such poles are large, and each pole must be provided with its own underground cable connection.
  • the present solar panel system tracks the sun from east in the morning to west in the evening and eliminates or reduces the aforementioned disadvantages of single-pole systems.
  • the present system is an improvement over a static system in that the efficiency is increased by at least 20-40% (the closer to the equator, the better) and the dimensions of the system on the ground are smaller for the same electric output. The amount of electric cable required is also reduced compared with single-pole systems.
  • the invention features a system for orienting solar panels, having a rotating frame for mounting the solar panels; wheels attached to the rotating frame; at least one rail forming a circular track for the wheels; and at least one motor for rotating the frame on the wheels around a central axis of the track.
  • the system may have more than one concentric circular track for the wheels, which may be flanged.
  • the frame may have a platform to which the wheels are attached and be inclined with respect to the platform.
  • Each of the solar panels may be individually inclined with respect to the rotating frame.
  • the frame may be a strut grid structure.
  • the system may also have a foundation for the at least one rail and/or a computer controlling motion of the rotating frame and/or of the rotating frame with respect to the platform and/or of each of the solar panels with respect to the rotating frame.
  • the circular track may be substantially parallel to the ground.
  • the rotating frame may have a platform, to which the wheels are attached, and be inclinable with respect to the ground.
  • Fig. 1 shows the rail tracks.
  • Fig. 2 shows a system for tracking sun with solar panels.
  • Fig. 3 shows a wheel mounting of the system' s frame on rails.
  • FIG. 4 shows another kind of wheel mounting of the system's frame on rails.
  • Fig. 5 shows an example of a wheel used in the system.
  • FIG. 6 shows an example of the frame used for the present system.
  • Figs. 7 and 8 show the system with an inclinable frame.
  • FIGs. 9 and 10 show the system with a frame inclined with respect to a platform.
  • FIG. 11 shows movement of individual solar panels.
  • Figs. 1 and 2 show a system for orienting an array of adjustable solar panels 1 mounted on a frame 6 and two concentric circular horizontal rail tracks 2 and 3 mounted via steel column supports 8 on a concrete footing and foundation 5 to rotate the frame 6 clockwise or counterclockwise around the central axis 20 using an electric motor 7 to follow the sun's motion in the sky for maximum utilization of available sun radiation.
  • the number of rail tracks and motors may be different for different situations and chosen for stability, strength, and durability.
  • Each rail track may be provided with its own motor or motors. These motors may be computer-controlled to rotate the frame 6 following the motion of the sun.
  • the frame support comprises joist trusses 29.
  • Each supporting column 8 may have a different length or height to compensate for uneven g &r- 1 ound and to ensure that the rail track 2 or 3 is level.
  • Figs. 3 and 4 show possible mountings of the frame 6 on the rail tracks 2 and 3.
  • One such mounting is shown by the rectangle 9 on Fig. 2 [ 0023 ]
  • the frame is mounted on wheels 10-11 or 14 as shown in Figs. 3 and 4, such as a flanged wheel shown in Fig. 5, via steel column supports 12.
  • the wheels 10-11 or 14 are secured to rail tracks 2 or 3 at top and bottom to enable the frame 6 to rotate on the tracks 2 and 3 and to prevent separation of the wheels 10-11 or 14 from the rail tracks 2 or 3.
  • the frame 6 may be designed and assembled in various ways: as a bar joist system or a simplified space frame shown in Fig. 6 with half-octahedrons 21.
  • a space frame or space structure is a truss-like, lightweight rigid structure constructed with interlocking struts in a geometric pattern.
  • Space frames usually use a multidirectional span and are often used to provide long spans with few supports. They derive their strength from the inherent rigidity of the triangular frame; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut. Often their geometry is based on platonic solids.
  • the simplest form is a horizontal slab of interlocking square pyramids built from aluminium or steel tubular struts.
  • this looks like the horizontal jib of a tower crane repeated many times to make it wider.
  • a stronger purer form is composed of interlocking tetrahedral pyramids in which all the struts have unit length. More technically, this is referred to as an isotropic vector matrix or in a single unit width as an octet truss. More complex variations change the lengths of the struts to curve the overall structure or may incorporate other geometrical shapes.
  • a grid 22 shown in Fig. 1 is attached to the top of the frame 6 using steel or aluminum L-shaped angles (similarly to an acoustical ceiling grid system). Each cell of the grid 22 holds a solar panel 1 and allows easy replacement of the solar panel 1.
  • the frame 6 may be attached to a steel platform 23 or to a bar joist frame.
  • the platform 23 is then attached to the wheels 10-11 or 14 on the rail track 2 with a movable frame support 24.
  • the frame 6 may be variably inclined with respect to the ground by a hydraulic elevating device 25, which may be computer controlled, to follow the sun's position in the sky.
  • the frame 6 may be set at a permanent angle to the ground and to the platform 23.
  • each individual solar panel 1 shown in Fig. 11 may change its angle to follow the sun. This may be computer-controlled.

Abstract

La présente invention concerne un système d'orientation de panneaux solaires, comportant : un cadre tournant pour monter les panneaux solaires ; des roues attachées au cadre tournant ; au moins un rail formant une piste circulaire pour les roues ; et au moins un moteur pour faire tourner le cadre sur les roues autour d'un axe central de la piste. Le système peut comporter plus d'une piste circulaire concentrique pour les roues, qui peuvent être à boudin. Le cadre peut comporter une plateforme, à laquelle sont attachées les roues, et peut être incliné par rapport à la plateforme. Chacun des panneaux solaires peut être individuellement incliné par rapport au cadre tournant. Le cadre peut être une structure à armature à étai. Le système peut également comporter des fondations pour le ou les rails, et/ou un calculateur contrôlant le mouvement du cadre tournant et/ou du cadre tournant par rapport à la plateforme et/ou de chacun des panneaux solaires par rapport au cadre tournant. La piste circulaire peur être sensiblement parallèle au sol. Le cadre tournant peut comporter une plateforme, à laquelle sont attachées les roues, et être inclinable par rapport au sol.
