Description

Technical Field

[0001] This disclosure relates to the field of marine photovoltaic technology, and more specifically, to a marine photovoltaic array and its support system. Background Technology

[0002] Traditional photovoltaic (PV) mounting systems are primarily designed for terrestrial environments. When these systems are applied directly to the sea, a series of problems arise. First, the undulating and dynamic nature of the sea places extremely high demands on the stability of the PV mounting system. Too many PV panels on the mounting system increase the overall weight and wind-exposed area, leading to decreased stability. Conversely, too few PV panels on the mounting system, while improving stability, reduce the installation efficiency of the PV project.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] This disclosure provides a marine photovoltaic array and its support system, which can increase structural stability while improving power generation and installation efficiency.

[0005] According to one aspect of this disclosure, a marine photovoltaic array is provided, comprising:

[0006] A photovoltaic support structure is installed above the sea surface. The photovoltaic support structure includes a support part with a bearing surface. The bearing surface is located on the side of the photovoltaic support structure away from the sea surface. The extended surface of the bearing surface forms a preset angle with the sea surface, and the preset angle is 10° to 25°.

[0007] Multiple photovoltaic panels are arranged side by side in an array on the bearing surface and connected to the bearing surface; the number of photovoltaic panels is 700 to 1000.

[0008] In one exemplary embodiment of this disclosure, the arrangement of the plurality of photovoltaic panels is 10 rows * 50 columns to 20 rows * 70 columns.

[0009] In one exemplary embodiment of this disclosure, the area of ​​the photovoltaic panel is 2 square meters to 5 square meters.

[0010] In one exemplary embodiment of this disclosure, the preset angle is 15°.

[0011] In one exemplary embodiment of this disclosure, the number of photovoltaic panels is 832.

[0012] In one exemplary embodiment of this disclosure, the photovoltaic panels are arranged in a 16-row x 52-column configuration.

[0013] In one exemplary embodiment of this disclosure, the photovoltaic support includes a plurality of first beams distributed along a first direction and extending along a second direction, and a plurality of second beams distributed along the second direction and extending along the first direction, wherein at least one of the first beams intersects with one of the second beams.

[0014] In one exemplary embodiment of this disclosure, the photovoltaic support further includes a grid frame located on the side of the first beam and the second beam away from the photovoltaic panel, and connected to the first beam and the second beam.

[0015] In one exemplary embodiment of this disclosure, the materials of the support and the space frame include one or more of metal, stainless steel, or aluminum alloy.

[0016] According to one aspect of this disclosure, a support system for a marine photovoltaic array is provided, comprising the marine photovoltaic array as described in any one of the above claims and a plurality of support columns, one end of each support column being fixed to the seabed and the other end extending above the sea surface, wherein the end of the support column above the sea surface is connected to the photovoltaic support, so that the marine photovoltaic array is positioned above the sea surface.

[0017] The disclosed offshore photovoltaic array and its support system have a bearing surface that forms an angle of 10° to 25° with the sea surface. The photovoltaic panels are mounted on the bearing surface, thus creating an angle of 10° to 25° with the sea surface. This angle range is designed based on a comprehensive consideration of the solar radiation angle, sea surface environmental characteristics, and photovoltaic panel performance. Within the preset angle range, the photovoltaic panels can receive solar radiation to the maximum extent, improving light energy conversion efficiency and thus increasing power generation. Simultaneously, the inclined bearing surface helps reduce the direct impact of waves on the photovoltaic support structure, enhancing its stability in the marine environment and reducing the probability of damage to the photovoltaic panels. Secondly, setting the number of photovoltaic panels between 700 and 1100 avoids the instability problems caused by excessive system weight and wind-exposed area due to too many photovoltaic panels, while ensuring installation efficiency. Precise quantity control achieves a balance between power generation efficiency, stability, and installation efficiency. Furthermore, the photovoltaic panels are arranged side-by-side in an array on the bearing surface, and the tight connection with the bearing surface ensures reasonable spacing and neat arrangement between the photovoltaic panels. This arrangement not only facilitates ventilation and heat dissipation between photovoltaic panels, reducing the impact of temperature on power generation efficiency, but also helps reduce shading and improve overall power generation efficiency.

Detailed Implementation

[0025] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0026] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0027] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc. The terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0028] Photovoltaic arrays can include a large number of photovoltaic panels. For example, multiple photovoltaic panels can be placed on a single photovoltaic support frame, and the number of panels directly determines the final power generation. Currently, the number of photovoltaic panels that can be installed on a single support frame is relatively small, which is not conducive to ensuring the final installation efficiency of photovoltaic projects. On the other hand, placing too many photovoltaic panels on a single support frame can lead to instability issues.

[0029] Especially for offshore photovoltaics, the field of offshore photovoltaic arrays is still in its infancy. How to set up photovoltaic arrays at sea, and how to reasonably control the number of photovoltaic panels on the photovoltaic support while ensuring stability and installation efficiency, are the key points and challenges of offshore photovoltaics.

[0030] Based on this, embodiments of this disclosure provide a marine photovoltaic array, such as... Figure 1 and Figure 2 As shown, the offshore photovoltaic array may include a photovoltaic support frame 1 and multiple photovoltaic panels 2, wherein:

[0031] The photovoltaic support 1 can be stably fixed above the sea surface. The photovoltaic support 1 may include a support part 101, which has a bearing surface 102. The bearing surface 102 is located on the side of the photovoltaic support 1 away from the sea surface. The extended surface of the bearing surface 102 forms a preset angle α with the sea surface. The preset angle α can be 10° to 25° to maximize the solar capture efficiency of the photovoltaic panel 2 and enhance the adaptability of the array to the changing marine environment.

[0032] Multiple photovoltaic panels 2 can be arranged side by side in an array on the bearing surface 102 and connected to the bearing surface 102; the number of photovoltaic panels 2 can be 700 to 1100. Within this range, it can ensure that the offshore photovoltaic array achieves a balance between power generation efficiency and structural stability.

[0033] Multiple photovoltaic panels 2 are arranged in an efficient and orderly manner. The specific arrangement can be flexibly adjusted within the range of 10 rows × 50 columns to 20 rows × 70 columns according to the actual situation, so as to adapt to different sea conditions, light angles and installation requirements.

[0034] The area of ​​each photovoltaic panel 2 can be set within the range of 2 to 5 square meters to ensure that the light energy conversion efficiency is maximized within a limited space, while maintaining the overall structural stability of the offshore photovoltaic array.

[0035] The following is a detailed description of each part and its specific details of the marine photovoltaic array in the embodiments of this disclosure:

[0036] Please continue reading Figure 1 As shown, the photovoltaic support 1 can be installed above the sea surface. The photovoltaic support 1 may include a support part 101, which can be securely connected to the seabed foundation or floating platform through connectors to ensure that the entire photovoltaic support 1 remains stable even in harsh marine environments. The support part 101 may be made of high-strength, corrosion-resistant materials. For example, the material of the support part 101 may include one or more of metal, stainless steel, or aluminum alloy. Of course, the material of the support part 101 may also be steel with a special coating on the surface to resist seawater corrosion and long-term wind and wave action.

[0037] Please continue reading Figure 1 and Figure 2 As shown, the support 101 has a bearing surface 102, which is located on the side of the photovoltaic bracket 1 furthest from the sea surface. The support 101 not only provides support but also directly supports the photovoltaic panels 2 via its top bearing surface 102. The bearing surface 102 can be flat to reduce efficiency loss due to uneven installation, simplify the installation process, and ensure close alignment between the photovoltaic panels 2.

[0038] In some embodiments of this disclosure, the bearing surface 102 may also be provided with positioning grooves or mounting holes to facilitate the rapid positioning and fixing of the photovoltaic panel 2, thereby helping to improve installation efficiency. For example, the bearing surface 102 may be designed with T-slots, which allow installers to adjust the position of the photovoltaic panel 2 according to actual needs, achieving flexible layout.

[0039] In some embodiments of this disclosure, the bearing surface 102 may also be designed as a slightly curved surface, such as a parabola or hyperboloid, to better capture sunlight from different angles. Furthermore, the bearing surface 102 may also be processed with specific textures, such as a microprism structure, to increase the number of light reflections and refractions, thereby improving light capture efficiency.

[0040] In some embodiments of this disclosure, the bearing surface 102 can be a hollow structure. The hollow bearing surface 102 can reduce the structural weight, promote air circulation, and reduce wind resistance while ensuring sufficient support strength, which is particularly important for the offshore photovoltaic support 1. For example, a honeycomb hollow design can be adopted, which can effectively disperse wind force and reduce costs by reducing the amount of materials used.

[0041] In this disclosure, taking the bearing surface 102 as a plane as an example, other details of the bearing surface 102 are explained:

[0042] The extended surface of the bearing surface 102 can form a preset angle α with the sea surface. For example, the preset angle α can be 10° to 25°. For example, the extended surface of the bearing surface 102 can form an angle of 10°, 15°, 20°, or 25° with the sea surface. Of course, the included angle between the extended surface of the bearing surface 102 and the sea surface can also be other angles, which will not be listed here.

[0043] It should be noted that the selection of the preset angle α is based on a comprehensive consideration of multiple factors, including local latitude, solar radiation intensity, seasonal variations, and the impact of the tilt angle of the photovoltaic modules on power generation efficiency. Within the preset angle range, the photovoltaic panel 2 can receive solar radiation to the maximum extent, improving light energy conversion efficiency and thus increasing power generation. Simultaneously, the tilted bearing surface 102 also helps reduce the direct impact of waves on the photovoltaic support 1, contributing to enhanced stability of the photovoltaic support 1 in a marine environment.

[0044] For example, in regions around 30° North latitude, based on the sun's annual trajectory, the bearing surface 102 can be set at an angle of 15° to the sea surface, which can better balance the amount of solar radiation received in winter and summer and maximize power generation efficiency.

[0045] In some embodiments of this disclosure, in order to achieve more flexible angle adjustment, the support 101 can be designed as an adjustable structure. For example, the tilt angle of the bearing surface 102 can be automatically adjusted according to seasonal changes through a hydraulic or electric drive system, thereby further optimizing energy collection efficiency.

[0046] In one exemplary embodiment of this disclosure, the area of ​​a single photovoltaic panel 2 can be between 2 square meters and 5 square meters. Within this range, the area of ​​a single photovoltaic panel 2 is moderate, which not only ensures the power generation efficiency of the single photovoltaic panel 2, but also avoids increasing the difficulty of installation, transportation, and maintenance due to an excessively large area.

[0047] For example, the area of ​​a single photovoltaic panel 2 can be 2 square meters, 2.5 square meters, 3 square meters, 3.5 square meters, 4 square meters, 4.5 square meters or 5 square meters. Of course, a single photovoltaic panel 2 can also have other areas, which will not be listed here.

[0048] Please continue reading Figure 2 As shown, multiple photovoltaic panels 2 can be arranged side by side in an array on the bearing surface 102. There can be a gap between adjacent rows or adjacent columns. This gap not only facilitates installation and maintenance, but also helps with ventilation and heat dissipation between the photovoltaic panels 2, reducing the decrease in power generation efficiency caused by temperature rise. At the same time, it also helps to reduce shading and improve the overall power generation efficiency.

[0049] In some embodiments of this disclosure, the arrangement of multiple photovoltaic panels 2 can be 10 rows * 50 columns to 20 rows * 70 columns. For example, the arrangement of multiple photovoltaic panels 2 can be 10 rows * 50 columns, 12 rows * 50 columns, 14 rows * 51 columns, 16 rows * 52 columns, 17 rows * 58 columns, 18 rows * 64 columns, 19 rows * 68 columns, or 20 rows * 70 columns.

[0050] In one exemplary embodiment of this disclosure, the photovoltaic panels 2 are arranged in a 16-row x 52-column configuration. When subjected to wind force, the photovoltaic panel array 2 can distribute stress more evenly, reducing the risk of structural damage caused by excessive stress at a single point. At the same time, the 16-row x 52-column configuration maintains high space utilization while ensuring good ventilation and heat dissipation and minimal shading, thereby maximizing power generation efficiency.

[0051] The photovoltaic panel 2 can be connected to the bearing surface 102, thereby fixing the photovoltaic panel 2 to the photovoltaic bracket 1. For example, the photovoltaic panel 2 can be detachably connected to the bearing surface 102, for example, by using aluminum alloy clamps or stainless steel bolts. Each photovoltaic panel 2 and the bearing surface 102 can have multiple connection points, and these connection points can be evenly distributed to ensure that the photovoltaic panel 2 is subjected to balanced forces, avoiding the risk of damage caused by excessive force at a single point.

[0052] The number of photovoltaic panels 2 can be between 700 and 1000. Within this range, it avoids the stability problems caused by excessive system weight and wind-exposed area due to too many photovoltaic panels 2, while ensuring the installation efficiency of photovoltaic panels 2. Through precise quantity control, a balance between stability and installation efficiency can be achieved. For example, the number of photovoltaic panels 2 can be 700, 800, 832, 900, or 1000. Of course, other quantities of photovoltaic panels 2 can also be used, which will not be listed here.

[0053] In one exemplary embodiment of this disclosure, such as Figure 3 As shown, the photovoltaic support 1 may include multiple first beams 11 and multiple second beams 12. Both the first beams 11 and the second beams 12 may be strip-shaped, and the cross-sections of the first beams 11 and the second beams 12 may be rectangular, polygonal, circular, elliptical or irregular in shape. No special limitation is made on the cross-sectional shape of the first beams 11 and the second beams 12 here.

[0054] Multiple first beams 11 can be distributed along a first direction x, and each first beam 11 can extend along a second direction y. For example, the first beams 11 can be evenly spaced along the first direction x, and the distance between two adjacent first beams 11 can be less than the length and width of a single photovoltaic panel 2. For example, each photovoltaic panel 2 can have at least two first beams 11 at its bottom, which can simultaneously support the photovoltaic panel 2 to ensure the stability of the photovoltaic support 1 for the photovoltaic panel 2. It should be noted that the second direction y intersects with the first direction x; for example, the second direction y can be perpendicular to the first direction x.

[0055] Multiple second beams 12 can be distributed along a second direction y, and each second beam 12 can extend along a first direction x. For example, the second beams 12 can be evenly spaced along the second direction y, and the distance between two adjacent second beams 12 can be less than the length and width of a single photovoltaic panel 2. For example, each photovoltaic panel 2 can have at least two second beams 12 at its bottom, which can simultaneously support the photovoltaic panel 2 to further ensure the stability of the photovoltaic support 1 for the photovoltaic panel 2. The first beam 11 can intersect with at least one second beam 12. In some embodiments of this disclosure, each first beam 11 can intersect with all second beams 12, and the intersecting first beam 11 and second beam 12 are detachably connected, thereby ensuring the overall stability of the photovoltaic support 1.

[0056] For example, the first beam 11 may have multiple first fixing holes spaced apart along its extension direction. These first fixing holes may be through holes and may be circular in shape. Correspondingly, the second beam 12 may have multiple second fixing holes spaced apart along its extension direction. When the first beam 11 and the second beam 12 intersect, each first fixing hole on the first beam 11 corresponds one-to-one with each second fixing hole on the second beam 12. Bolts can pass through the first fixing holes and the second fixing holes sequentially, with the end of the bolt passing through the second fixing hole exposed outside the second beam 12. A nut can be fitted onto the outer periphery of the exposed end of the bolt, and rotating the nut can fasten the first beam 11 and the second beam 12 together.

[0057] In some embodiments of this disclosure, after the first beam 11 and the second beam 12 are connected by bolts, the intersecting areas of the first beam 11 and the second beam 12 can be welded to enhance the connection stability between the first beam 11 and the second beam 12.

[0058] Both the first beam 11 and the second beam 12 can be made of high-strength, corrosion-resistant materials, such as metals, alloys, or stainless steel, to ensure long-term stable operation of the first beam 11 and the second beam 12 in harsh marine environments. The dimensions of the first beam 11 and the second beam 12 can be calculated based on the overall dimensions and weight of the photovoltaic panel 2 and the expected marine environmental conditions to ensure sufficient strength and rigidity.

[0059] In one exemplary embodiment of this disclosure, such as Figure 4 As shown, the photovoltaic support 1 may further include a grid frame 3. The grid frame 3 is located on the side of the first beam 11 and the second beam 12 away from the photovoltaic panel 2, and is connected to the first beam 11 and the second beam 12. The grid frame 3 can support the first beam 11 and the second beam 12. That is, the grid frame 3 can be located below the first beam 11 and the second beam 12. The grid frame 3 can be composed of crisscrossing rods or frames. The material of the grid frame 3 may include one or more of metal, stainless steel, or aluminum alloy. Its mesh structure not only provides a stable support platform for the first beam 11 and the second beam 12, but also effectively distributes the weight of the photovoltaic panel 2 and its components, effectively avoiding the occurrence of local overload. In this disclosure, the grid frame 3 can be connected to the first beam 11 and the second beam 12 by bolts, nuts, washers, angle brackets, etc., or by welding, etc. No special limitation is made here on the connection method between the grid frame 3 and the first beam 11 and the second beam 12.

[0060] Please refer to some embodiments of this disclosure. Figure 4 As shown, the space frame 3 may include a first support frame 31 and a second support frame 32. There are at least two first support frames 31, which are spaced apart and arranged in parallel. The first support frames 31 may be a mesh structure, and their material may be a rigid material with corrosion resistance. There are also at least two second support frames 32, which are spaced apart and arranged in parallel. The second support frames 32 may be a mesh structure, and their material may also be a rigid material with corrosion resistance. The material of the second support frames 32 may be the same as that of the first support frames 31. The second support frames 32 may be connected between the two first support frames 31, thereby forming a mesh frame resembling a rectangle.

[0061] In some embodiments of this disclosure, the space frame 3 may further include reinforcing struts 33. The reinforcing struts 33 may be rod-shaped and connected between two adjacent first support frames 31. There may be multiple reinforcing struts 33, which may be distributed in parallel. The reinforcement struts 33 enhance the support strength of the space frame 3, preventing deformation during use and helping to improve its service life.

[0062] This disclosure also provides a support system for a marine photovoltaic array; please refer to [link to relevant documentation]. Figure 1 As shown, the support system may include the marine photovoltaic array and support columns 4 as described in any of the above embodiments. One end of the support column 4 is fixed to the seabed, and the other end extends above the sea surface. The end of the support column 4 above the sea surface is connected to the photovoltaic support 1, so that the marine photovoltaic array is located above the sea surface. For example, the support column 4 may be connected to the photovoltaic support 1 or the grid 3 in the marine photovoltaic array. There may be multiple support columns 4, which may be evenly distributed along the circumference of the photovoltaic support 1. For example, the number of support columns 4 may be 4 to 12. For example, the number of support columns 4 may be 4, 6, 8, 10, or 12. Of course, other numbers of support columns 4 may also be used, which will not be listed here.

[0063] In one exemplary embodiment of this disclosure, the support column 4 may include a first segment 41, a second segment 42, and a third segment 43 connected in sequence, wherein;

[0064] The first section 41 is made of corrosion-resistant high-strength steel or composite materials, and may be conical or spiral in shape to increase the contact area and friction with the seabed soil, ensuring the stability of the support column 4 on the seabed. This section of the support column 4 is fixed by driving or screwing it into the seabed, and can resist the complex geological conditions of the seabed and long-term water erosion.

[0065] The second section 42 is located between the seabed and the sea surface and is also made of high-strength and corrosion-resistant materials. The design of this support column 4 needs to take into account the buoyancy of seawater, wave forces, and the influence of currents. Through reasonable cross-sectional shape and wall thickness design, the stability and durability of the support column 4 in seawater are ensured.

[0066] The third section 43 extends above the sea surface to directly support the offshore photovoltaic array. This support column 4 is typically designed as a column or truss structure to provide sufficient support and stability. Additionally, its surface can be treated with anti-corrosion coatings to extend its service life.

[0067] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
