At the in 1 illustrated exemplary solar tracking device 100 is a series of solar panels, eg. B. photovoltaic panels 102 , on two purlins 104 stored. In this example, there are six solar panels 102 and two purlins 104 However, it is understood that the solar tracking device 100 more or less solar panels 102 and more or less purlins 104 as illustrated. The purlins 104 can be on any number of swivel arms 106 be stored, for. B. as in 1 shown on two swivel arms 106 , At the midpoint or approximately at the midpoint of each pivot arm 106 For example, a bore may be provided which forms a support having an axis of rotation aligned with the row of solar panels. Each of these supports can be on a corresponding axis 108 be mounted on the top of a set of legs 110 , which acts as a support structure, may be located. Such a support axle assembly may be pivotal arms 106 and thus the solar panels 102 on purlins 104 are fixed, which at the swivel arms 106 are fixed, allow to rotate about an axis aligned with the row of cells.

In the non-limiting configuration, the in 1 is illustrated includes each set of legs 110 two feet 112 , In the configuration of 1 are the feet 112 on concrete tracks 114 mounted and attached thereto by adhesive. The concrete tracks 114 contain a mounting surface and act as a ballast foundation for the overall construction. Railways can also act as a guide for vehicles, for example solar panel maintenance and diagnostics machines. It should be noted that the feet 112 the solar tracking device, as in 1 shown standing on a gliding concrete bed or on two glazed concrete beds. Every foot 112 could alternatively be on individual blocks of concrete that can either be prefabricated or cast on site. Every set of two feet 112 a set of legs 110 could also be a normal alternative Use concrete foundation. Alternatively, every foot could 112 every set of legs 110 Use one or more elements that penetrate the ground as foundations, such as pegs, ground nails, ground screws or support pile foundations.

The rotation of the solar panels 102 can be powered by a motor running in 1 not shown separately. For example, the engine may be a drive shaft 116 drive. A drive wheel 118 can the torque and torque from the drive shaft 116 on the bow wheels 120 transfer. Legs, swingarms and bowwheel together make up an A-frame assembly 1 As illustrated, non-limiting configuration includes two A-frame assemblies, it is understood that more than two A-frame assemblies may be included per solar tracking device. The bow wheels 120 can each with the swivel arms 106 be connected and the pivot arms about their respective axis 108 rotate. In this way, the solar panels 102 rotatable with the drive shaft 116 (and thus with the engine) be coupled. Optionally, a clutch 122 with the drive shaft 116 and the drive shaft of another solar tracking device 100 coupled, z. B. for connecting Solarnachführvorrichtungen, so that the drive shaft of a first Solarnachführvorrichtung via the coupling 122 drives the rotation of the drive shaft of a second solar tracking device. There may be any number of solar tracking devices via such couplings 122 be connected to each other. In the configurations given herein, drive shafts may conveniently be hollow or solid shafts.

2A and 2 B schematically show detailed perspective views of certain components of in 1 illustrated exemplary solar tracking device. For example, show 2A and 2 B schematically detailed perspective views of the Bogenrads 120 and Antriebsradorgans 118 the in 1 illustrated exemplary solar tracking device 100 , 2 B is an enlarged view of 2A , In the in 2A-2B illustrated non-limiting configuration, the Antriebsradorgan 118 a series of teeth that span the teeth of the bow wheel 120 engage. In addition, a driving pin 202 at the drive wheel member 118 attached and rotatably connected thereto, and a locking plate 204 can at the bow wheel 120 attached and rotatably connected to this. The drive wheel member 118 and the backup plate 204 can together make a backup mechanism 200 as more fully described herein.

3 schematically shows another view of the solar tracking device of 1 , with certain elements omitted for clarity. For example, shows 3 schematically another view of the solar tracking device 100 from 1 but where the drive shaft 116 , the drive wheel organ 118 and the takeaway pen 202 have been omitted for clarity. 3 shows schematically that the teeth 302 of the bow wheel 120 not necessarily around the entire arc of the Bogenrads 120 have to continue around. For example, the bow wheel 120 at the location of the backup plate 204 a gap 304 between the teeth 302 include. In the area of the gap 304 grip the teeth of the Antriebsradorgans 118 represented in 2 , not in the teeth 302 of the bow wheel 120 one, so that the drive shaft 116 can turn without them the bow wheel 120 turns and thus without them the solar panels 102 rotates. If many tracking devices (eg via the clutch 122 ) Are connected to each other at the ends, so all can be arranged in alignment with each other, even if in the system rotational offsets are present, for. B. by gaps in the clutch 122 and rotations of the drive shaft 116 , 3 also shows schematically that the drive shaft 116 through a warehouse reception 306 Can be worn in a strut 308 is stored, which of the legs 110 is worn and gives this additional rigidity. As an alternative, a bearing retainer can be applied to the below with reference to 21A-21B way described be coupled with a leg so that it carries the drive shaft and the Antriebsradorgan.

4 schematically shows a perspective view of an alternative exemplary configuration of a solar tracking device. The exemplary configuration of 4 can the same bow wheel 120 like the example configuration in 1 and also a securing mechanism 400 include. A driving pin 404 can in the Antriebsradorgan 402 be integrated and extend from one side of the Antriebsradorgans to the other. In the same way as in 2A and 2 B can be a backup plate 406 at the bow wheel 120 to be appropriate. But in the exemplary configuration of 4 can the backup plate 406 two plates, each on one side of the bow wheel 120 are attached. Both parts of the backup plate 406 can from the takeaway 404 are driven. A drive shaft 408 may be a motor not specifically shown with the Antriebsradorgan 402 and the takeaway pen 404 connect. The cross section of the drive shaft 408 is in the in 4 cylindrical example illustrated, but it could be correspondingly rectangular or have a different shape. In the non-limiting configuration of 4 can the bow wheel 120 at appropriate places recesses 410 include, to prevent mutual obstruction of takeaway 404 and bow wheel 120 to prevent.

5 schematically shows a detailed view of an exemplary configuration of certain components of in 4 illustrated exemplary solar tracking device. For example, shows 5 schematically a detailed view of an exemplary configuration of the Antriebsradorgans 402 and the takeaway pin 404 , The drive wheel member 402 can along its axis a through hole 502 comprise and for receiving and engaging the drive shaft 116 be trained in what 1 and 2 is shown. The drive wheel member 402 can also drive gear organza 504 , a round contact surface 508 that the shape of the curved surface on the backup plate 406 corresponds, and recesses 506 , which are designed so that they have projections on the locking plate 406 allow yourself without disturbing the driver pin 404 to move, include. In some embodiments, the drive wheel member 402 be conical. For example, in a conical section of the Antriebsradorgans 402 the base of each tooth 504 be wider than the tip of each tooth. In some embodiments, a conical drive wheel member may reduce or minimize the possibility of binding or separating the drive wheel member and the bow wheel. For example, if the teeth are misaligned, they may be affected by the conical shape of the drive wheel member and the movement of the teeth in the 29 shown again be brought into the correct orientation. It is the reference number 2901 for: "Bogenrad". It is the reference number 2903 for: "Bogenrad". It is the reference number 2905 for: "Bogenrad". It is the reference number 2907 for: "Drive Radorgan". It is the reference number 2909 for: "Drive Radorgan". It is the reference number 2911 for: "Drive Radorgan".

6 schematically shows a detail view of an exemplary configuration of a component of in 4 illustrated exemplary solar tracking device. For example, shows 6 schematically a detail view of an exemplary configuration of the backup plate 406 , The backup plate 406 includes any suitable number of pin slots 602 , z. B. in the illustrated configuration, two pin slots 602 , and a reaction surface 604 , which has the shape of a circular arc, which, as in 5 shown, the curvature of the support surface 508 on the drive wheel member 402 equivalent. The pen slots 602 are trained to be the driving pin 404 to pick up the bow wheel 120 to advance into the storage position and a rotation of the additional drive shaft 408 to allow without the solar panels 102 rotate. The reaction surface 604 is adapted to the rotation of the bow wheel 120 by concerns on the bearing surface of the Antriebsradorgans 508 to secure. The safety gear 406 also includes a number of mounting holes 606 , z. B. four mounting holes 606 , which are adapted to the safety gear via corresponding mechanical fasteners on the bow wheel 120 to fix.

7A-7C 12 each schematically show detailed views of an exemplary configuration of the securing mechanism in three exemplary positions of the solar tracking device, illustrating, for example, how the tracking device rotates to follow the sun. In the in 7A shown position is the Antriebsradorgan 402 engaged with the bow wheel 302 and is the backup plate 406 not in engagement with the driving pin 404 and allows the bow wheel 120 , based on the rotation of the drive shaft 408 to turn. With the change of the tracking device from the in 7A illustrated position in the position shown in Figure 7B based on the further rotation of the drive shaft 408 the drive wheel member rotates 402 further and thereby causes the Bogenrad 120 , moving along the arch of the bow wheel 120 to move. Every backup plate 406 includes drive pin slots 602 , z. B. two Mitnehmerstiftschlitze 602 , where the driving pin 404 is designed to fit in any of these slots. 7B schematically shows a position in which the driving pin 404 in a slot 602 the backup plate 406 engages and teeth 118 the Antriebsradorgans 402 not with your teeth anymore 302 of the bow wheel 120 are engaged because of the gap 304 in the row of teeth of the bow wheel, as in 3 shown aligned with the locking plate. The interaction and interlocking of the driving pin 404 and the slot 602 in the backup plate 406 may cause the bow wheel 120 from the rotating drive wheel member 402 is turned. Similarly, the drive wheel member holds 402 if the takeaway 404 in the slot 602 engages, torques stood, which it z. B. by wind forces on the Bogenrad 120 is exposed. Further turning of the drive wheel member 402 about the rotation of the drive shaft 408 can the system in the in 7C shown position in which the driving pin 404 no longer in engagement with the locking plate 406 located. The drive wheel member 402 and the drive shaft 408 can now turn without the bow wheel 120 to rotate, which can be referred to as dwell or WindLagerungsstellung. In this phase or position, the bow wheel can 120 because of the engagement and the radial fit between the curved portion 604 the backup plate 406 and the cylindrical shoulder portion 508 the Antriebsradorgans 402 do not turn. If, for example, on the swivel arm 106 in the in 7C shown position, ie in storage mode, a torque (for example, through the solar panels 102 acting wind forces) would apply, this torque could lead to a force radially to in to the drive wheel member 402 and thus in the drive shaft 408 , Strut 308 , Legs 110 the tracking device and the track 114 would be directed. But in the in 7A or 7B shown position that can be on the swivel arm 106 applied torque (eg through the solar panels 102 acting wind) as torque on the drive shaft 116 , Clutch 122 and the drive motor (not specifically shown). In 7C now is the solar tracking device 100 Secured in this position and wind loads acting on the cells are conducted substantially into the frame and the foundation of the tracking device instead of the drive shaft and the motor. To continue the tracking, the drive shaft 408 the drive wheel member 402 and the takeaway pen 404 back in the 7B turn position shown, in which the pin 402 engaged with one of the slots of the backup plate 406 located. In this position causes a rotation of the driving pin 404 that is the bow wheel 120 rotates until the teeth of the Antriebsradorgans 402 into the teeth of the bow wheel 302 intervention.

A consideration for the design of the solar tracking device is the wind load. For example, in some configurations, the wind may exert a force on the solar panels, which in turn may apply torque to the drive shaft, thereby undesirably transmitting torque to the engine. In such a configuration, the motor and drive shaft may be configured to withstand torques of wind loads on all tracker sections to which the motor and drive shaft are connected. The design wind load is defined as the highest wind speed that the system could possibly be exposed to, but which is rarely expected. For example, a site might be exposed to wind speeds of 50 miles per hour once a year, with the site design point perhaps at 100 miles per hour, an event that may occur once every 200 years. In contrast, the wind speed for most of the operating hours of the solar system can remain below 10 miles per hour.

An exemplary approach for dealing with such a situation is to have the tracking device operate normally up to a limit wind speed of, for example, 40 miles per hour and to position it at wind speeds above the limit in a "storage position". By forming the tracking device with such various modes, phases or positions, the motor and drive shaft system may desirably have significantly lower rated torques than in the case where the motor must be designed to withstand the higher wind speed of the design point. Such a lower rated torque can save considerable costs. In a storage position, the tracking device could better withstand high wind speeds.

In addition, a reduction made by the Bogenrad together with the locking mechanism reduce the requirements of the engine, drive shaft and locking mechanism.

Advantageous features of the integrated security mechanisms 200 and 400 , as in 2A-7 shown, include one or more of the following: the Nachführvorrichtungsabschnitte are designed so that they can be rotated to a storage position, wind forces can be transmitted through the Nachführkonstruktion and the foundation instead of transmitted as torque through the drive shaft, and / or the torque requirement in operation be reduced.

An exemplary configuration for driving solar tracking devices includes a motor for driving a plurality of tracking device sections, wherein torque and force are transmitted via a drive shaft 116 to be transmitted via couplings 122 is connected, for. As with reference to 1 described. Between the motor shaft angle and the angle of the Antriebsradorgans 118 a tracking device section coupled to the motor may have an angular deviation due to clutch tolerances and torsion. One or a plurality of tracker section (s) may be coupled to the first tracker section and the greater the number of mechanical connections in the drive shaft along the row of tracker sections, the greater the angular deviation of the drive wheel member. All tracking device sections can be rotated to the storage position. In some configurations, rotating all tracker sections to the storage position may include each section being at substantially the same predetermined angle.

In some configurations, the backup mechanism, e.g. B. 200 in 2 and 400 in 4 to correct the angular deviation and to ensure that all tracking device sections coupled to a motor have substantially the same angle to each other for the storage position and that the securing mechanisms are engaged with all sections in the storage position. In a non-limiting example, the in 7A-7C Coupling section shown coupled directly to the drive motor, angled to the east and turns from 7A above 7B to 7C from east to west. The next tracking device section is coupled to the first section at the motor opposite end and may be slightly more angled toward the horizon and lag relative to the first section, for example because of the angular deviation, as both sections rotate from east to west. Additional tracking device sections may lag behind the first and second tracking device sections as the incremental angular deviation adds from one section to another. At the first Nachführvorrichtungsabschnitt the driving pin engages 404 , as in 6B , in the fuse plate 406 one, then dissolves, as in 7C , out of engagement with her, and then the Antriebsradorgan begins 402 to turn without the bow wheel 120 is turned. The first tracking device section is now in the storage position and the bow wheel 120 remains at its angle while the drive shaft 408 continues to turn. Since other coupled tracker sections farther from the motor may lag the first section in rotation, these sections may not yet have entered the storage position. While the drive shaft 408 continues to rotate, the first Nachführvorrichtungsabschnitt remains in the storage position and the coupled Nachführvorrichtungsabschnitte be brought one after the other in the storage position. The motor can be stopped after all tracker sections have reached the storage position. In this way, all coupled tracker sections are aligned substantially at the correct bearing position angle, and their safety mechanisms are engaged despite clutch errors in the drive shaft due to clutch tolerances and drive shaft misalignments.

Additionally or alternatively, the securing mechanism, for. B. 200 in 2 and 400 in 4 , then, when the tracking device is in the stored position, be configured to transmit the torque from the bow wheel 120 on the drive shaft 116 , as in 1 shown, inhibits or prevents and instead transmits wind forces from the bow wheel radially inwards to the center of the drive shaft to the point where the locking plates are located. For example, as above with reference to 7C described, the curved portion of the locking plate 406 be designed so that it fits snugly with the heel 508 the Antriebsradorgans 402 has, if the driving pin 404 and the gear teeth 504 are not engaged. In such a position can be any torque caused by wind on the swing arm 306 is applied, causing the locking plate 406 at the heel 508 the Antriebsradorgans 402 is applied. The bearing forces can then be radial through the drive shaft bearing 306 in 3 and in the leg construction 110 and the concrete foundation 114 in 1 be transmitted. When the locking mechanism is not engaged (eg, as described above with reference to FIG 7A described) wind forces acting on all Nachführvorrichtungsabschnitte can apply a torque which is reduced by the Bogenrad on the drive shaft and the motor. When the locking mechanism is engaged (eg, as above with reference to FIG 7C described), the wind load can be passed to the individual Nachführvorrichtungsabschnitten sections in the support structures of these individual sections, thus reducing the stress and rotation in the system by high wind loads or eliminated.

In certain circumstances, wind in a solar tracking device can excite oscillating vibrations. In configurations as stated herein, ie, with reference to FIG 1-7C , engagement of the teeth of the bow wheel with the arc teeth of the drive wheel member can damp such oscillating vibrations. In addition, the materials of both the Bogenrads and the Antriebsradorgans be chosen so that such damping is promoted, for. B. by a suitable reinforcement of the friction between Bogenrad and Antriebsradorgan.

21A and 21B 12 schematically show a perspective view of an alternative exemplary configuration of a solar tracking device. 21A schematically shows a perspective view and 21B schematically shows a detailed perspective view. The exemplary configuration includes solar panels rotated about a tracking axis that is parallel to the earth's surface and is oriented in a north-south direction. solar panels 2102 can be aligned along the tracking axis and on a rotary carrier 2104 to be appropriate. The rotary carrier in 21A and 21B has a square cross-section, but it may also be round or have a different shape. The rotary carrier 2104 can be aligned with the tracking axis. Stiffeners behind the panels can increase the structural rigidity in the transverse direction to the tracking axis. The assembly of solar panels 2102 , Stiffeners and swivel supports 2104 can by warehouse 2106 on posts 2108 be worn. Camps 2106 can be designed so that they allow the rotary carrier to rotate about the Nachführachse. The bow wheel and the staggered drive shaft may be configured to reduce or remove the torque from the pivot support, such that the pivot support may be provided with less strength, material, and / or cost than in configurations in which the pivot support has such torque in part has to endure. The posts 2108 may be mounted on ground screws, ground nails, concrete bedding, concrete foundations or any other type of foundation or support structure.

Further with reference to 21A and 21B For example, the solar tracking device may be driven by a motor (not specifically shown) that drives the drive shaft 2010 which drives via drive shaft bearings 2112 , which are also referred to as bearing receptacles, can be mounted on the post. The drive shaft 2110 can with drive wheel 2114 coupled as in the exemplary configuration in FIG 7 or in 2 can be designed to torque and force on the bow wheels 2116 transferred to. The bow wheels 2116 can be stiffened 2118 attached, which can be configured so that they torque and force from the bow wheels 2116 on the torque tube 2104 transfer. The exemplary configuration in FIG 21A and 21B includes two curved wheels 2116 in each tracker section, but in other configurations per section 2116 only a bow wheel 2116 or less than one bow wheel per section. As an example, the rotary carrier 2104 extend through several sections and for every third section a bow wheel 2116 be provided. The solar tracking device can be secured in strong wind with a safety mechanism that the Antriebsradorgan 2114 , the fuse plate 2120 and the bow wheel 2116 The same as for the exemplary configuration in 1-7C may be formed described.

A "storage position" for a solar tracking device may be considered as a position in which the tracking device is moved to such a position that it can withstand wind forces of particular magnitude or in which wind forces are significantly reduced. A tracking device may include one or more than one storage position. 22 schematically shows a perspective view of an exemplary configuration of a securing mechanism of a solar tracking device in a storage position. For example, shows 22 schematically the exemplary configuration of the solar tracking device mechanism of 1 in a storage position. This storage position is characterized in that the tracking device, the solar panels 102 from the prevailing wind (wind direction represented by big arrow) has turned. For example, the tracker can rotate the panels until the leech-free purlin 104 the legs, z. B. two sets of legs 110 , touched and resting on these legs. In this position, acting on the backs of the solar panels wind forces can cause the force of the wind-away purlin 104 on the legs 110 and transferred to the ground. This can lead to a transfer of torque into the drive shaft 116 (and thus in the drive motor) through the solar panels 102 acting wind forces is reduced, inhibited or prevented. Furthermore, wind forces on solar panels 102 in a group of solar panel sections 100 in all leg structures 110 instead of being concentrated on a mechanical element. The solar tracking device can rotate in one direction or the other to form a purlin 104 to the sets of legs 110 Optionally, a tracking device controller (not shown) may optionally select, for example, depending on the prevailing wind direction, in which direction to turn for storage. An example angle of the storage position is 60 degrees with respect to east or west. Optionally, a purlin or other moving part may be in contact with a stationary part such as an A-frame (leg) or leg. For example, in some embodiments, the purlin is in a storage position, as in FIG 22 shown in contact with the A-frame. For example, a potential shock from the impact of the purlin on the A-frame may be met by a cushioning member, a spring, a damper or other mechanism. In another example, the contact between purlin and A-frame provides additional strength to the structure to withstand wind and other forces. Limited storage of the sheet tracker may reduce or eliminate galloping, may reduce or eliminate / minimize torque transmitted to the drive system, and / or create no load interactions when the module / rotating member of the structure is pressed against a frame (ie, pressed ) becomes. A shock absorbing spring may be used to cushion the impact between the purlin ( 104 ) and the sentence of A-frame legs 110 to be ordered. According to some embodiments, various configurations include: spring, bumper or shock absorber. In examples of storage statics (load acting on the rotating part of the structure) causes one on the backs of the solar panels 102 attacking Windkraftresultante a force (Fr), which acts on a pivot pin, which force (Fr) on the (stationary) leg / frame attacks.

For example, an exemplary feature of the solar tracking devices disclosed herein 100 in that they are relatively fast and easy to assemble. One aspect of this is that a car 2000 as he is in 20 can be used to the Nachführgestell 100 over a stretch of concrete bedding 114 to transport, if necessary, as in 17 can be shown formed. In an exemplary method of preparing a solar tracking device, concrete bedding tracks 114 be formed. A tracking rack 100 can be prepared in a mounting room, possibly at the end of the concrete bedding track 114 can be located. The prepared tracking frame 100 can then, as in 20 shown on a cart 2000 can be loaded and the cart can then be longitudinally along the concrete track 114 be transported to a location at which the Nachführgestell is to be set up. Such a cart system can facilitate installations because the concrete track may be relatively long, for example.

The carriage can either be moved by pushing or pulling by hand or designed to be driven by an electric motor or other drive system.

24 schematically illustrates certain components during an exemplary method for mounting a solar tracking device. For example, includes 24 a diagram of steps ( 1 ) - ( 3 ), which in some configurations are referred to below with reference to 25 described method 2500 correspond. An example process includes mounting sheet tracker sections at one end of a track and transporting by railcar. The steps may include: ( 1 ) Assembly of the panel at the end of the track; ( 2 ) Moving the panel into position by means of the carriage and ( 3 ) Removing the panel from the cart and arranging on the track. A panel may support the rack assembly for a group of solar modules, e.g. B. of PV modules include or represent. The diagram in 24 schematically shows certain elements of the solar system site during construction, the location tracks, z. B. concrete tracks 114 , may include. At or near one end of a concrete railway track 114 can be a staging area 2402 may be provided, optionally a protective roof structure over a panel mounting area, such as the tent 2403 , may include. In the staging area 2402 For example, the solar tracking device designs can be assembled. For example, a partially assembled construction 2404 shown in step ( 1 ) on one dare 2000 is assembled, where appropriate, the car as in 20 be formed and used to move an assembled panel can be used. For example, the resulting assembled construction 2400 from the car 2000 in step ( 2 ) (corresponding to a carriage movement) along the track 114 moved to a suitable location, for example next to an already installed, assembled panel 100 , The assembled construction 2400 can in step ( 3 ) from the car 2000 on the track 114 to be moved.

25 schematically shows a sequence of steps in an exemplary method 2500 for mounting a solar tracking device. The procedure 2500 can forming a concrete track ( 2502 ). For example, as described above with reference to FIG 1 described, railway track 114 be formed by slipforming or extrusion and comprise a single concrete bed (track), which provides a first and second surface, which are designed so that the carriage can roll along it, or two separate concrete tracks, eg a first bedding, the provides a first surface for rolling along the carriage, and a second bedding providing a second surface for rolling along the carriage. A staging area may be at one end of the track ( 2504 ) are set up, for. B. a staging area 2402 as he relates to 24 is described. In the process 2500 may include a tracking structure (eg, panel) on a cart in a staging area (e.g. 2506 ) are built, for. B. can the construction 2400 partially assembled and then on the car 2000 in the staging area 2402 in the above with reference to step ( 1 ) in 24 be completely assembled. The procedure 2500 may also include moving the carriage along the track to a location where the tracking structure is to be installed ( 2508 ), e.g. B. can the car 2000 with the assembled construction (panel) arranged thereon 2400 on the first and second surface of the track 114 on the referring to step ( 2 ) from 24 described manner to a suitable location, for. For example, a location next to an already installed, assembled panel 100 to be rolled. For example, in a non-limiting configuration, workers may push the cart along the track to the location where the tracking structure is to be installed. The procedure 2500 can the taking down of the tracking structure of the car and arranging the construction on the track ( 2510 ), e.g. B. can the blackboard 2400 from the car 2000 taken down and suitably on the track 114 arranged as described above with respect to step ( 3 ) from 24 is described. For example, in one non-limiting configuration, workers can pick up the construction (panel) and place it on the track. In some configurations, the feet become 112 the tracking construction in grooves of the track 114 used. The procedure 2500 can also connect a coupling of Nachführkonstruktion with a coupling of the adjacent Nachführkonstruktion ( 2512 ), e.g. B. may be a coupling of the assembled panel 2400 with a clutch of in 24 assembled, already installed panel 100 get connected. Exemplary couplings are described herein with reference to 18 and 19 described. Such a compound may optionally be made by workers. The procedure 2500 also includes the application of adhesive to the feet of the tracking device to guide the tracking structure on the track (FIG. 2514 ) to fix. For example, in some configurations where the feet 112 the tracking construction in grooves of the track 114 adhesives are applied in the groove, for example by workers, to secure the tracker. The procedure 2500 can also attach solar panels to the tracking structure ( 2516 ), for example, before or after placing the tracking device on the tracking device and / or its attachment with adhesive. Alternatively, the solar panels in the staging area may be attached to the tracker construction, and the tracker structure with solar panels attached thereto may be brought to the installation site and installed there by the cart. The procedure 2500 may be repeated any suitable number of times for any number of tracking constructions (panels) to produce an elongate array (array) of solar tracking devices.

According to certain embodiments, a distributed foundation of the sheet tracker may allow mechanical stresses on the system components of the sheet tracker system to be reduced or minimized. For example, supports (legs) can be arranged at smaller distances so that each support is not stressed as much as at longer distances. In another example, more columns may be installed on outdoor rows with higher wind load, rather than increasing the size and / or strength of the columns. Various non-limiting examples, as in 26A-26B may include: ( 1 ) Outer rows - four A-frames (brackets) per panel, 2 quarter-turn actuators per row and drive shafts; ( 2 ) Border panels - three A-frames per panel; and or ( 3 ) Inner rows - two A-frames per panel, 1 rotary actuator per row and selected wall thickness of the drive shaft.

26A-26B Fig. 12 schematically show plan views of exemplary arrangements of solar tracking devices, optionally as described herein with reference to Figs 24 and 25 described can be installed. In the 26A The arrangement shown comprises two outer rows 2602 located on the outside of the solar panel and any suitable number of inner rows 2604 which are located between the outer rows (two inner rows 2604 are in for clarity 26 shown). Solar tracking devices can be designed to withstand wind forces. In a large solar field, the outer rows shield the inner rows of wind forces, so that the inner rows can be exposed to completely different forces than the outer rows. As stated herein, one way to reduce investment costs for installing the solar tracking devices is to design the outer rows other than the inner rows because they are exposed to other wind forces. In the in 26 In the non-limiting configuration shown, tracker sections may be designed differently and the number of sections per motor may be in-line 2604 unlike with outer rows 2602 be. In 26A Each small rectangle represents a tracking device section similar to that described above 1 described tracking device 100 can be trained. In an example configuration, the rectangles labeled "A" may 2606 in outer rows 2602 three sets of legs 110 per section and the rectangles marked with "B" 2608 in inner rows 2604 two sets of legs 110 per section. In such a way can the outer rows 2602 a greater structural strength than the inner rows 2604 exhibit while the inner rows 2604 at a lower cost than the outer rows 2602 can be produced, however, in view of the lower wind forces to which the inner rows 2604 are exposed, have sufficient strength. Additionally or alternatively, inline engines 2610 in larger quantities on outer rows 2602 as on inner rows 2604 which reduces the number of tracker sections per motor on outer rows. Reducing the number of sections per engine increases the overall stiffness of the mechanical system associated with the engine. The arrangement in 26B includes outer rows each having two pivot drives, each panel of the outer row may comprise four A-frame, and inner rows each having a pivot drive, wherein panels on the edge of the inner row may each comprise three A-frames and panels within the inner row two A-frames. It will be understood that any number of A-frames (or other Betsets) and quarter-turn actuators (or other in-line engines) may be used.

Exemplary connections between in-line motors (eg, rotary actuators) and rows of tracker sections are disclosed in International Patent Publication No. Hei. WO 2016/187044 , published on November 24th 2016 entitled "Systems and Methods for Rotating Photovoltaic Modules", the entire contents of which are incorporated herein by reference.

In example configurations, elements of the cart-based assembly may include an assembly area corresponding to a location where the rack components are assembled, and a cart corresponding to a cart that is used to transport materials at a project site, or that serves another purpose , include. The mounting area may include a rail end or a fixed area. For example, the mounting area may be at the end of a rail or other designated area at a project site. Activities in an assembly area may include attaching stiffeners to modules, assembling sheet tracker sections (eg, panels), and loading materials onto trolleys. The assembly area may also or alternatively be located outside of the site in a manufacturing facility or other location. Part of the assembly may be performed outside the assembly area, and part of the assembly may be performed in the assembly area. The trolley can move on rails or without rails. For example, carriages may be designed for travel on the concrete track, outside the concrete track or for a combination thereof. The trajectory of the carriage may include carriages traveling in various patterns on the worksite, for example in alternate directions on the tracks, or making trips to and from a designated assembly area.

In other exemplary configurations, the present tracking device may use a reduction gear between the bow wheel and the drive wheel member. For example, the reduction between two gears and the friction resisting their rotation may have the effect of counteracting the dynamics and vibrations of wind loads. Some examples of dynamics include flapping and galloping. To suppress wind induced vibrations, high damping may be used in accordance with some embodiments. For example, with gears, torques and drive stiffness are low, which can make it difficult to introduce high damping (eg,> 30%) without significant cost implications and engine size. In another example, instead of energy dissipation at the individual panels (and local reduction) is achieved via the interaction of materials (eg, sliding metal to metal).

In other exemplary configurations, the distributed gear actuator for damping and stiffening local moving components may include active positioning of an array of devices facing the sun, as well as any other arrangement of devices that may be positioned simultaneously and may require a low cost. provide. One application of such a configuration of actuation is with respect to a solar follower design. Such a construction may include solar photovoltaic panels mounted for the purpose of generating electric power. It is common for investors and power companies to construct large arrays of solar panels that can deliver as much power as would normally be provided by a coal, gas or nuclear power plant. A solar power plant can range in size from several hundred kilowatts of available power to more than 500 megawatts. One factor affecting the market and size of such power plants is the cost of energy produced over its lifetime, which is essentially the cost of construction and maintenance of the plant, since the source of energy is free. If the construction carrying the PV panels aligns the panels every day towards the sun, the power generation performance of the individual panels will increase compared to stationary panels. This reduces the cost of the scheduled energy when the additional cost of building and maintaining the solar tracking structure is compensated by an even greater increase in power generation capacity over the life of the power plant.

Recent advances in solar power plant power plant technology have focused on the cost of tracking actuators by increasing the solar collector area actuated by a microcontroller and a motor. The overall cost of the tracking actuation system can be reduced by reducing the number of potential sources of error for a given power output. An exemplary configuration of actuator and tracking design for this strategy is to place all of the solar panel panels on a component that can rotate about one or more axes to track the sun. This single component, which rotates around a solid foundation to follow the sun, may be referred to as a movable frame. When it becomes impractical for a single moveable frame to support another solar collector surface, various power transmission methods are placed between adjacent frames. In this way, more than 100 kW of solar PV can track the sun when actuated by a motor and a microcontroller.

In implementing an architecture of solar tracking devices with a large solar panel area compared to their one controller and their one motor, the rigidity of the system can become a significant design and cost factor. In an arrangement of devices whose position is controlled by an actuator, the further a single device or a point on a device is from the actuator, the more flexible the arrangement with respect to the actuated position commanded by the actuator. This phenomenon can occur because each material has a modulus of elasticity in which pressure units face the stress, so that the less force is required for equivalent deformation, the farther the component is from the impact point (on the actuator). This problem can be solved simply by stiffening the moveable frame component, but this is difficult without sacrificing structural strength and causing unnecessary overhead costs. When a construction is stiffened by making the same support members thicker, their strength also increases the ratio of strength to need and uses more material than would be required for the application. Another method of stiffening the design is to increase its moment of inertia, resulting in larger outer dimensions and thinner sections of material for a carrier of the same weight. Both stiffening methods generate additional costs of the movable construction. Thus, with careful consideration of the size of the collector surface (or an element whose position is to be controlled) per actuator and the additional material cost, some active positioning arrangements have been designed which allow a sufficiently rigid construction to meet the performance requirements of the tracked device.

Although wind loads and deformations of structures can be calculated with modern data and engineering practices, in the PV tracking market it has usually been that the structures were subjected to elastic deformation resonance at a wind speed that was not sufficiently predicted in the design phase of the design. This is largely due to the repetitive patterns in the arrangements in which an elastic plane of movement of a segment of an assembly is upstream with respect to an identical elastic element of the assembly. The pattern identical adjacent elastic elements of the assembly results in vibration feedback being transmitted from one element to the next, which may continue over many adjacent elements of the same configuration. Because of this, many solar tracking devices that have long elastic elements subject to substantial deformation under wind load use oil damping struts that can eliminate resonant motions of such an elastic element of an assembly. However, providing oil-immersion struts, in turn, causes more cost, complexity, and reduces the reliability of such a cost-sensitive mechanism even further.

The distributed transmission actuation for damping and stiffening local moving components can increase the stiffness of a positioned member that is at a substantial distance from the actuator that provides the reaction to its various positions. Exemplary distributed transmission operating architecture configurations may provide a position actuating force through a small drive shaft that may be routed from the central actuator to the individual elements of the arrangement to be positioned. Between the drive shaft and the individual elements to be positioned is a gear with a reduction ratio of the gears. The reduction is such that the drive shaft for the change in angle of the element to be positioned must undergo a larger deflection angle. An exemplary solar PV tracking device that currently utilizes this distributed actuation architecture has a 9 to 14: 1 gear ratio between the drive shaft and the tracked PV module. The stiffness of the output member (the PV panel) and the fixed member (actuating motor) may vary with the square of the gear ratio when the torsion member (eg, the drive shaft) has the same rigidity between compared systems. In addition to the deformation torques transmitted to the drive shaft through the reduction gear, there are local reactions on the gear bearings which transmit the translations of the torques of deformation directly to the local bearing located near the element to be positioned. The local response of the positioned element is unique in that it allows some of the forces acting on the positioned element to be locally applied to support that element. In a system with no reduction for its positioned elements, all external forces acting on that element, which are not translational (which rotate about the bearing seat of the element), must be translated by the control element directly connected to the actuator motor. In this way, a distributed drive shaft, which actuates individual elements of an assembly via a transmission, have increased rigidity and distribute the reaction to external forces by means of local support elements.

In addition to increasing the stiffness and load distribution to local support members, distributed transmission actuation has the advantage of providing a simple means of dissipating energy to the individual actuation gears. The means of energy dissipation is through friction between the drive shaft and its bearings. It should be noted that this frictional energy dissipation also occurs when there is no distributed transmission actuation architecture, but it has been demonstrated that frictional energy dissipation is more easily controlled, practically reliable, and cheaper in a distributed transmission actuation architecture.

Examples of damping and local reduction include a sheet tracking device: more metal-to-metal surfaces than a tracking device without reduction, thus opportunities for further friction damping; and / or a greater displacement of the drive shaft on the tracking device: friction losses in the gear train in places with the strongest displacement, and there are also friction losses in places with low displacement, but these are smaller.
