Possibility (s) to carry out the invention

Overview:

One terrestrial solar power system converts sunlight into electrical Energy using, for example, using multiple arrangements Arrangements spaced in a grid over the earth. The arrangement of solar cells has a special optical size and a special aspect ratio (aspect ratio) (For example, between 1: 3 and 1: 5), the arrangement for the Movement in one piece on a transverse arm of a vertical girder is held, who runs after the sun. The arrangement can Subassemblies, sections, modules and / or panels (panels) exhibit.

Of the Solar tracking mechanism allows the plane of the Solar cells resistant to the sun during the Passing the sun through the sky during the day indicating the amount of sunlight impinging on the cells is optimized. The power generated by the arrangement is in direct relation with the on the assembled solar cells incident sunlight. As a given arrangement many (For example, 1,000 and more) may have solar cells is it is advantageous to maintain the solar alignment of the entire array. However, this is difficult in practice as it is not uncommon is that an arrangement over 18 feet wide (59 feet) and 7.5 meters high (about 25 feet). Considering the given size of the arrangement, can the solar cells are misaligned near the circumference, namely due to bending or deflection of the assembly. The bending or the deflection may be, for example, as a result of the wind or as a result of the weight of the assembly, what bending the structure results. Such a misalignment is as little as 1 degree or less for some implementations damaging and it is desirable to bending or to minimize deflection of the assembly.

Implementations of a terrestrial Solar cell system.

An implementation of a terrestrial solar cell system is in 1A shown. Generally speaking, the system has three major components. The first main component is the center carrier ( 11a and 11b ). The center carrier is mounted on a surface and is able to rotate about its longitudinal axis. Depending on the implementation, the surface may, for example, be the earth or a concrete foundation formed in the earth. Located on or adjacent to the surface is a drive mechanism 100 (For example, a gear box), which provides the coupling with that with the central support. The drive mechanism 100 allows the inner link 11b relative to the outer member 11a rotates, for example, to move the solar cell array, such that the sun is tracked.

The second main component is the support frame 15 , The supporting frame 15 is coupled or coupled to the center carrier and is suitable for use with a solar cell arrangement (for example, arrangement 10 to wear). The third major component is the solar cell array 10 , The solar cell arrangement 10 has multiple sub-assemblies or panels or plates 16 on and is with the support frame 15 coupled and is supported by this. The solar cell arrangement 10 converts sunlight into electricity and is normally kept pointing to the sunlight by rotating the center support. In this implementation, each of the solar cell subassemblies is 16 in 13 sections 17 divided. Every section 17 has a 2 by 2 panels (plates) of concentration lenses (e.g. element 19b in 3 ), each lens being located above a single receiver (e.g. 19 of the 3 and 4 ) is arranged. The receiver, a printed circuit board or subassembly, includes a single III-V compound semiconductor solar cell, along with additional circuitry such as the bypass diode (not shown). In some implementations, each section is 17 a module, for example a discrete arrangement. In some implementations, the sections are 17 separated from each other by perforated dividers.

In the illustrated implementation, the center carrier has an outer member 11a and an inner link 11b on. The outer link 11a is connectable with bolts, with a support attached to the surface by bolts. The inner link 11b is rotatable within the limb 11a arranged and supports a cross member 14 , which with a support frame 15 connected is. The supporting frame 15 is also on the inner link 11b carried, by a pair of inclined arms 14a , each of two of the support posts 55b (visible in 1B ) extend, to the base of an inner member 11b , The inclined arms 14a are interconnected by a cross member 14b (see also 1B ) coupled or coupled, which increases their structural integrity. The attachment of the support frame in this way ensures that the attachment to the inner member 11b such is done that turners about its central longitudinal axis through the links 11a . 11b is rotatable.

The supporting frame 15 has a rectangular frame 15a and a prop 15B , The rectangular frame has two shorter links (see Elements 15a-3 and 15a-4 of the 1B ) oriented in a direction parallel to the height (cf. Dimension "C" of 1B ) of the solar cell array 10 and two longer links (see the components 15a-1 and 15a-2 of the 1B ), which are parallel to the width in one direction (see dimension "A" of FIG 1B ) of the solar cell array 10 are oriented. In this implementation, the width of the rectangular frame is approximately equal to the width of the solar cell array 10 although this configuration results in improved rigidity (eg, less bending of the solar cell assembly 10 near its perimeter) this is not necessary. For example, to reduce material costs, the width of the rectangular frame 15a be reduced.

The support 15B is with the rectangular frame 15a coupled in a manner that the rigidity of the rectangular frame 15a is increased and in this way the rigidity of the solar cell array 10 , The support therefore improves the alignment of the constituent solar cells (especially those near the periphery) such that power generation is significantly improved. The support 15b may serve the deflection of more than one degree near the periphery of the solar cell array 10 to prevent.

In this implementation, the prop has 15b a lower column string, an upper column string 152c a parallel pillar reinforcement strand 152b and diagonal struts 52a on. The parallel column reinforcement strands 152b and the diagonal struts 152a are between the upper and lower 152c and 152d coupled. The parallel column reinforcement strands 152b are substantially parallel to each other and perpendicular to the upper and lower support strands 152c and 152d arranged. The special configuration of the strands 152a to d can change with the implementation. For example, the support 15b have no diagonal column strands (eg, a Vierendeel post), no parallel column reinforcing strands, such as a grid support, or the relative orientation of the diagonal column strands may change (e.g., a Pratt post or a Howe post).

In this implementation is the prop 15b with the rectangular frame 15a by supporting members 151a coupled. Also, in these implementations, the rectangular frame and the support 15b integrated, that is, the lower column strand 152d indicates one of the longer members of the rectangular frame 15a on. In this implementation is the width of the prop 15b (For example, the width of the lower strand 152d ) approximately equal to the width of the solar cell array 10 and the rectangular frame 15a , Although this configuration improved rigidity (for example, less bending of the solar cell array 10 However, the configuration is not required, for example, can not reduce the material cost, the width of the support 15b be reduced.

In this implementation, the prop is 15b arranged such that the direction of their height (that is, the vertical direction between the lower column reinforcement 152d and the upper column reinforcement 152c ) is substantially orthogonal to the plane defined by the height and width of the solar cell array 10 , Although this configuration may have improved rigidity, it is not required. For example, to meet the packaging requirements, the support 15B be coupled such that the direction of their height is not substantially orthogonal to the plane defined by the height and width of the solar cell array 10 ,

In the illustrated implementation case is the support 15b not in the vertical center (that is along the dimension "C" of the 1B ) of the solar cell array 10 arranged. The inventors realized that the arrangement of the prop 15bb above the vertical centerline of the solar cell array 10 improved maneuverability with respect to the center support allows. As a result, the center support may be the solar cell array 10 move to follow the sunlight, without interference by the presence of the support 15b ,

Although the illustrated implementation is a prop 15b used the rigidity of the rectangular frame 15a other structures are possible. For example, a massive plate can be used. In another example, the solid or solid plate may be used with one or more cutouts. In addition, a very simple prop can be used, which is the ropes 152a and 152b can use, compared to a simple coupling of the upper column strand 152c with the lower column strand 152d , The post may have one or more additional links parallel to the upper post string 152c run.

1B is a rearward view of the terrestrial solar cell system of 1A , wherein the solar cell array 10 oriented orthogonally to the surface on which the central or central support is mounted (for example the earth). As shown, the prop is 15b along the largest vertical dimension (ie along dimension "A") of the assembly 10 aligned. This is advantageous since the arrangement is generally more for bending along a longer axis than along a shorter axis (for example, along the dimension "C") tends. In this implementation, the dimension "A" is the width of the solar cell array 10 , approximately 18.1 meters (approximately 59.4 feet), the dimension "B", the width of the subassembly 16 , is approximately 1.8 meters (approximately 5.9 feet) and the dimension "C", the height of the solar array 16 , is approximately 7.5 meters (approximately 24.6 feet). One such implementation has a solar collection area of approximately 98.95 square meters (approximately 1065.1 square feet) and weighs approximately 10191 kilograms (approximately 10.03 tons). In a design consistent with this disclosure, an implementation can withstand wind at 145 kilometers per hour (approximately 90.1 miles per hour).

In 1B is the view of the support 15B is largely covered because it is orthogonal to the plane defined by the height and width of the solar cell array. However, this view illustrates the support members 151a which the prop 15b with the rectangular frame 15a couple. In particular, see the support members 151 a clutch with a long link 15a1 or 15a2 of the rectangular frame 15a (in this implementation, the lower long link 15a2 ) and. the upper column strut or column strand 152c (see. 1A ) in front. In this implementation, there are four support members 151a shown diagonally. If the support members 151a run diagonally, this offers the advantage of resistance to tension and compression is not necessary. Also, depending on the implementation, more or fewer support members can 151a be used.

This view also shows additional features of the rectangular frame 15a , In order to improve the structural integrity, several cross members couple 150a the upper long link 15a1 with the lower longer limb 15a2 , The transverse or cross limbs 150a be through the parallel links 150b (which in this implementation is substantially parallel to the shorter links 15a3 and 15a4 are oriented). Two of the parallel links 150b serve the additional purpose of providing an attachment point with which the cross member 14 is coupled.

This view in turn demonstrates that the width of the rectangular frame 15a has approximately the same width as the solar cell array 10 (ie the width is about 18.1 meters). This view also illustrates the location of the column 15b above the center line of dimension "C".

1C illustrates an implementation of a terrestrial solar cell system with the height and width of the solar cell array 10 level, oriented parallel to the surface to which the center bracket is attached (to ground, for example). This implementation uses a prop 15b ' in a slightly different configuration, from which the prop 15b , This prop 15b ' leaves the parallel support reinforcement strands 152b away, for the use of all diagonal support strands 152a , 1D illustrates a perspective view of a support frame 15 who is the prop 15b ' having.

1E is a simplified view of a terrestrial solar cell system as seen from a direction perpendicular to the plane through the height and width of the solar cell array 10 is defined. As shown, the support ( 15b or 15b ' depending on the implementation) above the centerline of the dimension C arranged. Also, the prop is ( 15b or 15b ' ) in this implementation at a right angle (θ) with respect to the solar cell array 10 arranged.

1F FIG. 12 is a side view of an implementation of a terrestrial solar cell system viewed from a direction perpendicular to the plane defined by the height and width of the solar cell array. FIG 10 , As shown, the prop is ( 15 or 15b ' depending on the implementation) above the centerline of the dimension C arranged. Due to the arrangement of the support above the vertical center of the solar cell arrangement, the support obstructs the movement of the arrangement relative to the center support ( 11a . 11b ) Not. A pressure screw (jack screw) 111 and a matching threaded rod 112 together can set the angle (or inclination) of the arrangement 10 adjust over at least part of the path through the path 113 specified area. This is the pressure screw 111 (For example, in combination with a drive mechanism such as part 100 of the 1A ) capable of supporting frame 15 to pivot and thus the arrangement 10 with their angle with respect to the earth's surface.

2 FIG. 14 is a perspective view of the solar cell system implementation of FIG 1A , seen from the opposite side. This perspective illustrates the subdivision of each subassembly into sections 17 , Every section 17 has a base 18 on which is a structural or structural foundation for each recipient 19 (see. 3 and 4 ). In some implementations, there is a base 18 per sub-assembly 16 , divided by each constituent section 17 , In some implementations, the base is different 18 structurally from each section 17 ,

3 is a sectional view of a solar cell subassembly 16 that a section 17 on the base 18 represents. In this implementation, the section points 17 a surface element 320 including a 2 × 7 matrix of Fesnel lenses ( 20a - 20j are shown), a 2 × 7 matrix of secondary and optical elements ("SOE", an example is as an element 201 shown) and a 2 × 7 matrix of solar cell receivers 19 (fourteen are shown including the elements 19a - 19j ). In some implementations, the surface element is 320 an integral plastic plate and each Fesnel lens (for example, elements 20a - 20j ) is approximately a 22,86 cm (9 inch) square. In the illustrated implementation, each Fresnel lens (e.g. 20b ) and its associated receiver (for example 19b ) and SOE (for example 201 ) are aligned so that the light is concentrated by the lens optimally received by the solar cell of the associated Emp catcher. In the illustrated implementation, the section is 17 from the base 18 separated, by a divider 301 which can be perforated. The base 18 also serves to distribute heat from the receivers and in particular from the individual solar cells.

4 illustrates a receiver 19b in detail. The recipient 19b has a plate 203 , a printed circuit board ("PCB") 204 , an SOE 201 and a fixture 202 , The plate 203 Couples the receiver 19b to the base 18 (see the 2 and 3 ). In some implementations, the disk is 203 of a material having a high thermal conductivity such that the heat is efficiently dissipated by the PCP204 (which includes, for example, a solar cell and a bypass diode). In some implementations, the disk is 203 made of aluminum. In some implementation, the PCB points 204 a ceramic plate on, with printed electrical paths.

The attachment 202 that with the plate 203 Coupled or coupled at two positions forms a bridge, which is the SOE 201 with the solar cell of the PCB 204 aligns. The SOE 201 Collects the light from its associated lens 20 and focus it into the solar cell on the PCB 204 , In some implementations, each solar cell receiver 19 with a corresponding SOE 201 fitted. The SOE 201 has an optical inlet 201 and an optical outlet (located on the PCB 204 indicates) and a body 201b on. The SOE 201 is mounted such that the optical outlet above the solar cell of the PCB 204 is arranged. In some implementations, the SOE has 201 a generally square cross-section of the inlet 201 tapered towards the outlet. The inside of the surface 201c the SOE reflects light down to the outlet. The insides of the surface 201c In some implementations, it is coated with silver or other high reflectivity material. The path from the optical inlet 201 to the optical outlet forms a tapered optical channel, the solar energy from the corresponding lens 20 captures and directs them to the solar cell.

In a specific implementation as shown in plan view 5 is shown, the sub-assembly has a height of about 7.5 m (y-direction) and 1.8 m width (x-direction) and has sections 17 each of which has a 2 × 7 matrix of Fresnel lenses 20 and receivers 190 owns (see the 3 and 4 ). Every receiver 19 generates 13 watts of DC power with full AM 1.5 solar irradiance. The receivers are connected in parallel or in series by electrical cables, so that the aggregate 182 in an entire sub-array 16 can generate more than 2,500 watts DC peak power. Each of the subassemblies is in turn connected in series, so that a typical arrangement (eg element 10 ) can generate over 25 kW of power.

A motor sees the drive to rotate the link 11b relative to the limb 11a before and another motor provides the drive for rotation of the cross member 14 (and thus the support frame 15 ) relative to the middle carrier 11 around its longitudinal axis. Control means (for example arranged in the drive mechanism 100 of the 1 ) are for controlling the rotation of the member 11b provided, and relative to the member 11a and further for controlling the rotation of the cross member 14 (and the support frame 15 ), to its axis, to ensure that the flat outer surface of each of the sections 17 , the Fresnel lenses 20 , orthogonal to the sun's rays. In some implementations, the control means is a computer controlled machine using software that controls the motors depending on the azimuth and the level of the sun relative to the system. In some implementations, each of the Fresnel lenses focuses 20 the incident sunlight on the solar cell in an associated receiver (eg element 19b ), by a factor of more than 500X, whereby the conversion of sunlight into electricity with a conversion efficiency of over 37% is achieved. In some implementations, the concentration is 520X.

Further, in some implementations, the system is disruptive and uses an acrylic Fresnel lens to achieve the 520X concentration with an f # of approximately 2. An incidence angle for an individual cell / optic system is +/- 1.0 degrees. The efficiency or efficiency of the optical system in the sun is 90% with the angle of incidence defined at a point where the system efficiency is reduced to not more than 10% of the maximum. However, some implementations define a different angle of incidence, for example +/- 0.1 degrees. In some implementations, each solar cell is assembled in a ceramic package having a bypass diode and two spaced connectors. In some implementations, the 182 cells are configured in a sub-array. The number of cells in a sub-array is specified such that at maximum illumination the added voltages do not exceed the operating specifications of the inverter.

Implementations of a procedure for Assembly of a terrestrial solar cell array

6A FIG. 3 illustrates an implementation of a method for assembling a terrestrial solar cell array (eg, the implementation of the 1C ). Before the assembly begins, however, the place is selected where the assembly is to be built ( 600 ). Several factors can be useful in site selection, such as exposure to light and shadows.

Once the appropriate location is selected, a foundation for an assembly is built in ( 601 ). The foundation can be designed and designed for each location. Depending on the conditions at the site, additional reinforcement may be required, for example due to soil composition and topography. The 6B and 6C illustrate an implementation of a foundation 601e , In this implementation 1st the foundation 601 dimensioned at approximately 4.26 m (14 feet) square.

In the in the 6B and 6C implementation shown is the foundation 601 with a cast-in-place concrete, with a compressive strength of at least about 2.7 x 10 ⁴ kPa (4000 PSI), after a curing time of 28 days. In this implementation, the edges of the concrete have a 1.9 cm (3/4 inch) taper or taper. The foundation 601 may comprise reinforcing steel, manufactured and used in accordance with International Building Code Requirements and the Standard Manual (eg, ACI 31 5-99). anchor bolts 601b , embedded in the foundation 601 can as ASTM F1554 Grade 55 (or equivalents) with ASTM A563 heavy hex nuts, along with ASTM A 436 Washers.

As in 6A shown, the next block (602) refers to the attachment of the cross member 14 on the center girder ( 11a . 11b ) and the attachment of inclined arms 14a , As in 6D shown, becomes the cross member 14 on the inner member 11b with bolts 602d appropriate. The inclined arms 14a are at the opposite ends of the cross member 14 attached, at attachment points 602a and 602c , The attachment points 602a and 602c For example, they may include a nut and bolt combination. The other end of each inclined arm 14 is on the inner link 11b secured, via attachment points 602b (only one is visible in this perspective).

Next is the central carrier 11a . 11b on the foundation 601 (Block 603 ) Installed. The central or middle carrier 11a . 11b is on the foundation 601 in 6E installed. In some implementations, the central carrier points 11a . 11b Alignment marks on, the alignment with alignment marks on the foundation 601 make to indicate the true south direction. In some implementations, the central vehicle is 11a . 11b brought up to level and connected and to construction bolts ( 601b of the 6C ), using flat washers and tree nuts.

To the rotation of the inner link 11b relative to the outer member 11a Next, the gearbox will allow 604a aligned and incorporated (block 604 ).

In some implementations, the support frame is 15 equipped with two sections. In such implementations, the two sections must be assembled (block 605 ). The 6F illustrates a support frame 15 that consists of two sections 605a and 605b which were assembled.

Next is the support frame 15 on the cross member 16 (Block 606 ) attached. As in 6G shown is the cross member with the parallel links 150b (see 1B ) of the support frame 15 at attachment points 606a and 606c coupled. The Attachment points can for example have a nut and bolt combination.

To allow tilting of the solar array to various angles, a pressure screw is installed (block 607 ). As in 6G shown is the screw 607 with the cross member 14 coupled and also with the support frame 15 , The screw 607a couples the support frame 15 at the fastening point 607b , In this implementation, the attachment point points 607b a generally cylindrical member which changes the angle of the support frame 15 allowed when the bracket screw 607a moves in a generally vertical direction.

Next, the sub or sub-arrays (e.g., element 16 ) on the support frame 15 (Block 608 ) Installed. For example, the installation may use building bolts that pass through the support frame and the coupling with each subassembly 16 produce.
