Description

Solar battery system and installation method thereof

technical field

The present application relates to a solar cell system and an installation method thereof.

Background technique

There is a large and rapidly growing market for rooftop solar cell systems installed on commercial, industrial and municipal buildings. According to the research report of IHS, an information consulting company headquartered in Colorado, the total installed capacity of solar battery systems in the world in 2011 was 27.6 million kilowatts, and the total installed capacity of solar battery systems installed on commercial, industrial and municipal buildings was as high as 899. Ten thousand kilowatts.

A solar cell system includes a solar cell module and a mounting structure. Generally, there are two ways to install solar cell systems on commercial, industrial and municipal buildings, one is the rail mounting method, and the other is the adhesive mounting method.

The rail installation method usually includes the following steps: assembling the rail, planning the arrangement of the solar cell system, placing the poles of the rail on the roof, drilling mounting holes in the roof (usually through the waterproofing layer), using anchor Bolts in the mounting holes secure the rail frame to the roof, mount the solar cell modules to the rail frame, connect the ground wire, and connect the solar cell system to the inverter. By using the rail frame, the solar cell module can obtain a required installation angle.

In the rail installation method, the rail is assembled and fixed to the roof, so the operation is cumbersome and time-consuming, and the rail itself constitutes a considerable part of the cost of the solar cell system.

Additionally, existing rail mounting methods typically penetrate the building's waterproofing. The waterproof layer usually includes asphalt waterproof materials (including linoleum, rubber paint, ointment, etc. made of natural asphalt, petroleum asphalt and coal tar pitch as the main raw materials), rubber and plastic waterproof materials (including neoprene rubber, butyl rubber, etc.) , EPDM rubber, polyvinyl chloride, polyisobutylene, polyurethane, etc. Waterproof materials (including thin steel sheets, galvanized steel sheets, profiled steel sheets, coated steel sheets, etc.). Penetration of the waterproof layer will lead to a decrease in the waterproof performance of the building, which will lead to phenomena such as leakage.

For the adhesive mounting method, the structure of a solar cell module typically includes a polymer front film and a fiber-reinforced plastic (FRP) backsheet (as opposed to a standard module structure with a glass front film and a polymer backsheet). The back side of this form of thin and semi-rigid solar cell module is glued with double-sided tape, then the release film is removed from the double-sided tape, and the solar cell module is adhered on the flat roof with the double-sided tape. Compared with the rail installation method, the adhesive installation method is simple to operate, has lower cost, and will not damage the waterproof layer.

In the adhesive installation method, since the solar cell module is directly attached to the roof, the roof is required to have a high degree of flatness, and it cannot meet the best installation angle required for the solar cell module to work (for example, in the middle and lower reaches of the Yangtze River, the most The best installation angle is 25 degrees to 30 degrees). Moreover, the solar cell system covers a considerable part of the roof surface after installation, and this will also affect the quality assurance of the roof waterproof layer (because the protection of the waterproof layer usually requires that the waterproof layer is not covered by a large area). In addition, there is no space for air circulation between the solar cell module and the roof, so the heat dissipation performance of the solar cell module is poor.

Therefore, there is a need for an improved solar cell system installation measure to solve the aforementioned problems in the prior art.

detailed description

Various preferred embodiments of the present application are described below with reference to the accompanying drawings.

First, a solar cell system according to a first basic embodiment of the present application is shown in FIG. 1 , which includes a solar cell module 1 and a stand for mounting the solar cell module on a supporting surface (not shown).

The solar cell module 1 has a first laterally extending edge 11 and an opposite second laterally extending edge 12 . At this time, the first laterally extending edge 11 is lower than the second laterally extending edge 12 .

In order to receive as much sunlight S as possible, the installation angle of the solar cell module needs to be considered. First, the angle between the plane where the solar cell module is located and the horizontal plane is called the installation inclination angle. For general applications, the installation inclination angle can be 0 to 65 degrees, preferably 5 to 20 degrees, for example, the installation inclination angle is 5 degrees or 10 degrees.

On the other hand, another important installation angle when solar cell modules are installed is the installation azimuth. The installation azimuth of the solar cell module is the angle between the vertical plane of the solar cell module pointing to the center of the earth and the longitude of the earth. When the installation inclination angle of the solar cell module is 0 degree, the so-called vertical plane of the solar cell module pointing to the center of the earth refers to the vertical plane parallel to the meridian of the earth. Generally, when the vertical plane pointing to the center of the earth of the solar cell module is due south (due north in the southern hemisphere), the installation azimuth is 0 degrees. When the installation azimuth angle is 30 degrees, the power generation of the solar cell module will be reduced by 10% to 15%.

The solar cell module 1 is supported at its first laterally extending edge 11 and at its second laterally extending edge 12 by supports. In the example shown in FIG. 1, four supports support the four corners of the solar cell module 1, wherein two lower first supports 10a are supported on the lateral ends of the first laterally extending edge 11, two The taller second support 10b is supported on two lateral ends of the second laterally extending edge 12 . However, it can be understood that the number and arrangement positions of the first and second supports can be selected arbitrarily according to needs. For example, one of the first and second laterally extending edges may be supported by one stand and the other by two or more stands. Additionally, the location where the first and second laterally extending edges are supported by the stand may be located between the two ends.

As shown in FIG. 1, the first support 10a includes a first bottom plate 2a and a first support portion arranged on the first bottom plate (for example, integrated with the first bottom plate), and the first support portion has a The first support surface at the first height above the bottom surface of 2a is used to support the first laterally extending edge 11 , and the first support portion is supported on the first bottom plate 2a by the first strut 3 .

The second support 10b includes a second bottom plate 2b and a second support portion arranged on the second bottom plate (for example, integrated with the second bottom plate), and the second support portion has a second support portion located above the bottom surface of the second bottom plate 2b. The second support surface at the second height is used to support the second laterally extending edge 12 , and the second support portion is supported on the second bottom plate 2 b by the second support rod 4 .

Due to the requirement of supporting the solar cell module 1 obliquely and considering whether the supporting surface itself has a slope, the first height is less than or equal to the second height.

The first and second base plates have planar bottom surfaces adapted to conform to a support surface. For example, the first and second bottom plates are flat. Also, the first and second base plates preferably have the same size and shape for ease of manufacture and installation. In the illustrated example, the first and second base plates have a generally rectangular shape, however, other shapes, such as circular, oval, polygonal, square, triangular, composite shapes, irregular shapes, etc., may also be used.

Likewise, the cross-sectional shapes of the first and second struts may be circular, elliptical, polygonal, square, triangular, combined shapes, irregular shapes, and the like.

The first and second mounts used in the solar cell system shown in FIG. 1 are shown in FIG. 2 . It can be seen that a first support portion 6-1 is provided on the upper end of the first support rod 3 . In the illustrated example, the first supporting portion 6-1 includes a supporting surface (in the form of a flat surface shown in the figure, other forms may also be used) 6a supporting the bottom surface at the first laterally extending edge of the solar cell module and from The lower laterally extending edge of the supporting surface 6a generally extends upwardly with a stop 6b for holding the first laterally extending edge of the solar cell module. The support surface 6a is inclined at an oblique angle relative to the bottom surface of the first bottom plate 2a so as to adapt to the installation inclination angle for supporting the solar cell module. The stop 6b projects preferably perpendicularly to the support surface 6a.

Similarly, the upper end of the second pole 4 is provided with a second supporting portion 6-2. In the illustrated example, the second supporting portion 6-2 includes a supporting surface (in the form of a flat surface shown in the figure, other forms may also be used) 6a supporting the bottom surface at the second laterally extending edge of the solar cell module and from The upper laterally extending edge of the support surface 6a generally extends upwards with a stop 6b for holding the second laterally extending edge of the solar cell module. The support surface 6a is inclined relative to the bottom surface of the second bottom plate 2b at the aforementioned oblique angle so as to adapt to the installation inclination angle for supporting the solar cell module. The stop 6b projects preferably perpendicularly to the support surface 6a.

As an alternative or in addition to said support portion, a locking structure adapted to lock the first or second laterally extending edge of the solar cell module may be provided on the first and/or second strut. The locking structure can also be arranged at different height positions of the first pole and/or the second pole.

As an example, the locking structure may be a form-fitting structure, such as a plug-socket type locking structure, a snap-type locking structure, a threaded locking structure (for example, by passing through or screwing into the support surface shown in FIG. 2 bolt or screw in hole 6c in 6a) and so on.

The supporting part and the locking structure may be integral parts of the first and second supports, or components formed separately and then assembled on the first and second supports.

As shown in Figure 2, in order to improve the connection strength between the pole and the bottom plate, the first support 10a includes at least one reinforcing member (such as reinforcement ribs) 5, the second support 10b includes at least one reinforcement member (such as reinforcement ribs) 5 for strengthening the connection between the second strut 4 and the second bottom plate 3 .

The quantity and arrangement position of the reinforcement members 5 on each support can be specifically selected according to needs.

In the example shown in FIG. 1, the bottom surfaces of the first bottom plate 2a of the first support 10a and the second bottom plate 2b of the second support 10b are coplanar. In this way, the entire solar cell system can be mounted on a flat support surface. However, the present application does not exclude the embodiment that the bottom surfaces of the first bottom plate 2a of the first support 10a and the bottom surface of the second bottom plate 2b of the second support 10b are not coplanar, in this case, the entire solar cell system can be Mounting on a non-flat support surface such as steps or undulations.

According to an unshown feasible implementation manner of the present application, in order to improve the supporting strength of the first and second supports, connecting rods may be provided to connect some or all of the first and second support rods. If the first and second struts are all connected by connecting rods, an integral frame can be formed. However, it should be pointed out that such connecting rods are not essential. Under the condition that the supporting strength of the first and second support itself is sufficient, there is absolutely no need to arrange such a connecting rod.

In the example shown in Figures 1 and 2, the first strut 3 extends perpendicular to the first bottom plate 2a, and the second strut 4 extends perpendicular to the second bottom plate 2b. This configuration is beneficial to stand itself upright on the support surface without tipping over. However, the present application does not exclude embodiments in which the struts are not perpendicular to the corresponding bottom plate.

According to a possible implementation manner of the present application, each bottom surface of the first and second bottom plates has a certain contact area with the supporting surface. The selection of the contact area should ensure that the solar cell system has sufficient installation strength to resist wind or other loads (such as snow loads and collisions by foreign objects, etc.).

According to a possible embodiment of the present application, the first and/or the second support can be formed from metal or plastic material, preferably each as a one-piece structure.

When the first and/or second support is made of metal, the support has high strength and long service life, but the support itself is heavy, and the entire solar cell system needs insulation and/or grounding treatment . In contrast, standoffs made of plastic, such as insulating plastic, may not require insulation and/or grounding, are corrosion resistant, and weigh less. Of course, the strength and lifespan of plastic standoffs is lower than that of metal standoffs.

As mentioned above, the height of the first pole 3 is less than or equal to the height of the second pole 4 . The height of the first strut 3 may be in the range of 0.01m to 1m, preferably in the range of 0.01m to 0.1m. The height of the second pole 4 may be in the range of 0.01m to 1.5m, preferably in the range of 0.02m to 0.4m. The difference in height between the first and second struts is preferably within 0.2 times the length of the assembly.

According to a feasible implementation manner of the present application, the first pole 3 and/or the second pole 4 has an adjustable height (for example, constituted by a telescopic rod), and the adjusted height can be locked. In this way, by adjusting the height of the first and/or the second pole, the installation inclination angle of the battery module can be changed. The height adjustment of the pole can be realized electrically or manually.

According to the application, said first and second seats may rest directly on the support surface. In order to fix the positions of the first and second supports on the support surface, the first and second supports may be pressed by counterweights such as ballast blocks.

According to an important idea of the present application, the first and second supports (more specifically, the first and second bottom plates) may be configured to be fixed on a supporting surface by adhesive. In this case, when installing the solar cell system of the present application, first install the corresponding installation positions on the bottom surfaces and/or supporting surfaces of the first and second bottom plates of the first and second supports (such as FIG. 3 or Apply adhesive to the installation location shown in 4). Then, the first and second mounts are secured to the support surface using an adhesive. Then, install the solar cell module on the first support and the second support, thus forming the solar cell system shown in FIG. 1 .

The adhesive can be made of strong and durable materials, such as adhesive materials with properties such as resistance to solar radiation and water resistance. Furthermore, the adhesive should provide sufficient bond strength and longevity between the first and second mounts and the support surface to avoid detachment of the first and second mounts from the support surface.

In order to improve the bonding strength between the first and second mounts and the supporting surface, the bottom surfaces of the first and second bottom plates may be treated, eg roughened, before the adhesive is applied.

Additionally, the mounting location of the support surface may be pretreated prior to application of the adhesive to help improve the bond strength between the mount and the support surface and/or for other purposes. For example, pre-treatment of the mounting location of the support surface may include at least one of the following: marking, cleaning, roughening, heating, drying, wetting, chemical treatment, opening suitable for receiving the first and second base plates pits.

It should be pointed out that opening a recess suitable for receiving the first and second bottom plates at the installation position of the support surface can facilitate the positioning and orientation of the first and second supports relative to the support surface. Furthermore, in this case, both the bottom surfaces and the edges of the first and second base plates can be applied with adhesive, so that the bonding strength between the stand and the support surface can be further improved.

A solar cell system and its installation method according to a possible embodiment of the present application have been described above with reference to FIG. 1 , the solar cell system includes a solar cell module 1 supported by a support. According to a further possible embodiment of the present application, the solar cell system comprises a plurality of solar cell modules supported by a support. For example, the solar cell system shown in FIG. 3 includes a row of a plurality (two are shown) of solar cell modules 1 arranged side by side in a lateral direction, and each solar cell module is bounded at its edge by a first support 10a shown in FIG. supported by the second support 10b. It can be seen that at the corners where the two solar cell modules 1 adjoin each other, the two solar cell modules 1 can be supported by common first and second supports. In this way, a row of solar cell modules 1 can be formed in the lateral direction. The solar cell modules are supported at their first lower transversely extending edge by a first support 10a and at their second higher transversely extending edge by a second support 10b. The heights of the first supports are substantially equal, and the heights of the second supports are also substantially equal, so that the solar cell modules in a row are substantially coplanar, as shown in FIG. 3 .

Further, the solar cell system includes multiple rows of solar cell modules arranged side by side vertically. For example, a possible array arrangement of the solar cell system is shown in FIG. In a row, wherein the second support 10b supporting the solar cell modules in the previous row is adjacent to the first support 10a supporting the solar cell modules in the adjacent row. In this way, the solar battery modules in each row are arranged in random order (not in the same plane), and point in roughly the same direction.

FIG. 5 shows another possible array arrangement of the solar cell system, in which a plurality of solar cell modules 1 are arranged in rows horizontally and in columns vertically. The lowest laterally extending edge of the solar cell system (the first laterally extending edge of the solar cell module at the lowest position) and the highest laterally extending edge (the second laterally extending edge of the solar cell module at the highest position) are respectively supported by the aforementioned first support 10a and the second support 10b, while the respective intermediate solar cell module edges located longitudinally between the lowest transversely extending edge and the highest transversely extending edge are supported by the intermediate support 10c shown schematically in FIG. 6 . As shown in Fig. 6, the intermediate support 10c includes an intermediate bottom plate 2c and an intermediate support portion provided on the intermediate bottom plate (for example, integrated with the intermediate bottom plate), and the intermediate support portion has an intermediate height above the bottom surface of the intermediate bottom plate 2c. The middle support surface at is used to support the edge of the middle solar cell module, and the middle support part is supported by the middle support rod 7 on the middle bottom plate 2c.

The height of the intermediate support 10c is between the first support 10a and the second support 10b, that is, the intermediate height is greater than or equal to the first height but less than or equal to the second height. Depending on the number of rows in the solar cell module array, different types of intermediate support 10c can be provided with stepped intermediate heights.

The support surface 6a is inclined relative to the bottom surface of the second bottom plate 2b at the aforementioned oblique angle so as to adapt to the installation inclination angle for supporting the solar cell module.

A stopper 6b for holding the first laterally extending edge of the solar cell module is also formed on the second step 18 and generally extends upward from the higher laterally extending edge of the supporting surface 6a. The stop 6b projects preferably perpendicularly to the support surface 6a. Furthermore, the sides of the boss 6d define a stop surface 6e for holding the longitudinally extending edge of the solar cell module.
