An embodiment of the present disclosure provides a photovoltaic power generation system, including a photovoltaic tile and a support. The photovoltaic tile is mounted on ground or a building main body through the support. The building main body includes, but is not limited to, roofs and walls of buildings such as plants and warehouses of production enterprises. The present disclosure is described by taking the roofs as an example.

A specific structure of the photovoltaic tile is shown in <FIG>. The photovoltaic tile includes a plurality of color steel tiles <NUM> and a photovoltaic module <NUM>. The photovoltaic module <NUM> is mounted on the color steel tiles <NUM>. The color steel tiles <NUM> are mounted on roofs of buildings such as plants and warehouses of production enterprises through the support, so as to facilitate the solar power generation to meet daily usage requirements. The photovoltaic tile has a first direction X, a second direction Y, and a third direction (not marked in the figures) perpendicular to one another. The first direction X is a width direction of the color steel tiles <NUM>, the second direction Y is a height direction of the color steel tiles <NUM>, and the third direction is a length direction of the color steel tiles <NUM>.

A plurality of photovoltaic modules <NUM> are fixedly connected to one of the color steel tiles <NUM> along the third direction, and a distance S between adjacent photovoltaic modules <NUM> satisfies: <NUM>≤S≤<NUM>. The distance between the adjacent photovoltaic modules <NUM> may be <NUM>, <NUM>, or <NUM>. If the distance between the adjacent photovoltaic modules <NUM> is excessively small (i.e., S<<NUM>), the adjacent photovoltaic modules <NUM> may shield each other, which leads to reduction in operation efficiency of the photovoltaic modules <NUM>. During mounting, due to mounting and machining errors, problems such as abutment and interference easily occur between the adjacent photovoltaic modules <NUM>, resulting in difficulties in mounting of certain photovoltaic modules. If the distance between the adjacent photovoltaic modules <NUM> is excessively large (i.e., S><NUM>), the total number of the photovoltaic modules <NUM> that can be mounted on the color steel tile <NUM> is reduced, thereby reducing operation efficiency and usability of the photovoltaic tile. Therefore, <NUM>≤S≤<NUM> can improve mounting stability of the photovoltaic modules <NUM> and improve operation stability of the photovoltaic modules <NUM>, thereby improving the operation efficiency and the usability of the photovoltaic tile.

In some embodiments, a distance S between adjacent photovoltaic modules <NUM> satisfies: <NUM>≤S≤<NUM>. The distance between the adjacent photovoltaic modules <NUM> may be <NUM>, <NUM>, or <NUM>. Therefore, <NUM>≤S≤<NUM> can further improve the mounting stability of the photovoltaic modules <NUM> and further improve the operation stability of the photovoltaic modules <NUM>.

As shown in <FIG>, the photovoltaic module <NUM> includes a first solar cell string <NUM>, a second solar cell string <NUM>, and a third solar cell string <NUM>, and a jumper wire <NUM> is arranged between the first solar cell string <NUM> and the second solar cell string <NUM> or the second solar cell string <NUM> and the third solar cell string <NUM>. The first solar cell string <NUM>, the second solar cell string <NUM>, and the third solar cell string <NUM> are configured to convert light energy into electric energy. The arrangement of the jumper wire <NUM> between the first solar cell string <NUM> and the second solar cell string <NUM> or the second solar cell string <NUM> and the third solar cell string <NUM> enables the solar cell string at the very edge to be protected by a diode, reducing a hot spot effect and reducing a possibility of damages to the photovoltaic modules <NUM> due to overheating.

As shown in <FIG>, the color steel tile <NUM> includes a male rib <NUM> and a female rib <NUM> arranged at two ends along the first direction X. A folding portion <NUM> protruding upward along the second direction Y is arranged between the male rib <NUM> and the female rib <NUM>. Along the first direction X, bottom plates <NUM> are arranged on two sides of the folding portion <NUM>. The bottom plates <NUM> each have one end connected to the folding portion <NUM> and the other end connected to the male rib <NUM> or the female rib <NUM> through a connection portion <NUM>. The folding portion <NUM> can improve wind drag performance of the color steel tile <NUM>. The top of the folding portion <NUM> may be arranged as an arc or a plane, and a width of the plane may range from <NUM> to <NUM>.

The bottom plate <NUM> is provided with a reinforcing strip <NUM>. When the photovoltaic tile is used in a heavy wind environment, airflow flows through an upper surface of the color steel tile <NUM>, which reduces pressure of the upper surface of the color steel tile <NUM>, so that a pressure difference exists between an upper surface and a lower surface of the bottom plate <NUM> of the color steel tile <NUM>. In this case, the reinforcing strip <NUM> and the bottom plate <NUM> near the reinforcing strip <NUM> may locally deform under the pressure difference to reduce the risk of failure of connection between adjacent color steel tiles <NUM>, thereby improving stability of connection between the adjacent color steel tiles <NUM> and between the color steel tiles <NUM> and the roof.

When the adjacent color steel tiles <NUM> are fixedly connected, the female rib <NUM> is lapped on adjacent male ribs <NUM>, and the female rib <NUM> is fixedly connected to the male ribs <NUM> on the adjacent color steel tiles <NUM> by overlocking through an overlocking tool (not shown in the figures), so as to simplify the connection structure of adjacent color steel tiles <NUM>, thereby reducing the space required by the mounting of the color steel tiles <NUM>. An angle α of the overlocking satisfies: <NUM>°≤α≤<NUM>°. For example, the angle of the overlocking may be <NUM>°, <NUM>°, or <NUM>°.

In the present disclosure, the angle of the overlocking is a bending angle between the male rib <NUM> and the female rib <NUM>. If the angle of the overlocking is excessively small (i.e., α<<NUM>°), the male rib <NUM> and the female rib <NUM> have poor overlocking strength, and the male rib <NUM> and the female rib <NUM> are easily separated under external force, resulting in failure of connection between the adjacent color steel tiles <NUM>. If the angle of the overlocking is excessively large (i.e., α><NUM>°), difficulty of the overlocking is increased, which increases the time spent in fixing the adjacent color steel tiles <NUM>. Therefore, <NUM>°≤α≤<NUM>° can increase strength of connection between the male rib <NUM> and the female rib <NUM>, thereby improving stability of the connection between the adjacent color steel tiles <NUM> and, at the same time, reduce mounting difficulty of the color steel tiles <NUM> and reduce the mounting duration of the color steel tiles <NUM>.

In some embodiments, the angle α of the overlocking satisfies: α=<NUM>°.

In the present disclosure, the angle of the overlocking is <NUM>°, which can further improve the stability of the connection between the adjacent color steel tiles <NUM> and further reduce the mounting duration of the color steel tiles <NUM>.

Since the female rib <NUM> is fixedly connected to the male ribs <NUM> of the adjacent color steel tiles <NUM> by overlocking, the connecting end <NUM> formed after the connection of the female rib <NUM> and the male rib <NUM> has a connecting gap. If the connecting end <NUM> is exposed, water may drop on the connecting end <NUM>, then move along a sidewall of the connecting end <NUM> in rainy or snowy weather, and finally enter the roof through the connecting gap, resulting in leakage of the roof.

In order to solve the above problem, in some embodiments, as shown in <FIG>, the connecting end <NUM> is provided with a connecting plane <NUM> extending along the first direction X, and along the second direction Y, the connecting gap between the female rib <NUM> and the male rib <NUM> is located below the connecting plane <NUM>.

In the present disclosure, since the connecting gap is located below the connecting plane <NUM>, the water on the connecting plane <NUM> can slide down along the sidewall of the connecting end <NUM> along the second direction Y and drip down to the bottom plate <NUM> of the color steel tile <NUM> under gravity, so as to reduce the risk of the water entering the roof through the connecting gap and improve airtightness of the photovoltaic tile and the roof, thereby improving operation stability of the photovoltaic power generation system.

In some embodiments, as shown in <FIG> and <FIG>, a projection of the connecting end <NUM> along the third direction may be in the shape of T, L, U, or other alternative structures. During actual manufacturing, the shape of the connecting end <NUM> may be adjusted as required, so as to improve structural flexibility of the connecting end <NUM>. The specific shape of the connecting end <NUM> is not specially limited in the present disclosure, and the shape of L is only taken as an example in the drawings for illustration.

In addition, as shown in <FIG>, the connecting plane <NUM> is higher than the highest point of the folding portion <NUM>, which reduces the risk of increasing the overlocking difficulty of the male rib <NUM> and the female rib <NUM> caused by the small connecting end <NUM>, thereby reducing the difficulty of the connection between the color steel tiles <NUM> and reducing the mounting duration of the color steel tiles <NUM>.

In some embodiments, as shown in <FIG>, two ends of the photovoltaic module <NUM> are respectively connected to the folding portions <NUM> of the adjacent color steel tiles <NUM>. After the photovoltaic module <NUM> is connected to the color steel tile <NUM>, the photovoltaic module <NUM> is located above the connecting end <NUM> along the second direction Y. In rainy or snowy weather, the water may drip on the photovoltaic module <NUM> and move above the folding portion <NUM> along the photovoltaic module <NUM>. Since the folding portion <NUM> is of a closed structure, the water cannot enter the roof through the folding portion <NUM>. In addition, the photovoltaic module <NUM> covers the connecting end <NUM>, which reduces the risk of the water entering the roof through the connecting gap, thereby reducing the risk of the leakage of the roof.

As shown in <FIG> and <FIG>, the color steel tile <NUM> is further provided with a support portion. After the photovoltaic module <NUM> is connected to the color steel tile <NUM>, the support portion can abut against the photovoltaic module <NUM>, which increases support force of the color steel tile <NUM> on the photovoltaic module <NUM>, reduces the risk of local downward collapse and deformation of the photovoltaic module <NUM> along the second direction Y (the collapse and deformation of the photovoltaic module <NUM> may be caused by its own gravity or external force, such as water, rain, snow, or dust piled on the photovoltaic module <NUM>), thereby improving mounting stability of the photovoltaic module <NUM>, and prolongs the service life of the photovoltaic module <NUM>, thereby improving operation stability of the photovoltaic power generation system.

In some embodiments, the support portion is fixed to the color steel tile <NUM> as a separate part, so as to facilitate maintenance and replacement of the support portion and also facilitates adjustment of the height of the support portion along the second direction Y, thereby improving the support effect of the support portion on the photovoltaic module <NUM>.

In some other embodiments, the bottom plate <NUM> of the photovoltaic tile is locally deformed to form the support portion, so as to reduce the space required by the mounting of the support portion.

In some other embodiments, as shown in <FIG>, the connecting end <NUM> formed by the connection of the female rib <NUM> with the male rib <NUM> on the adjacent color steel tile <NUM> serves as the support portion, which reduces the space required by the mounting of the support portion, simplifies the structure of the color steel tile <NUM>, and reduces the size of the color steel tile <NUM>, thereby reducing manufacturing costs of the color steel tile <NUM>.

In the present disclosure, description is based on an example in which the support portion is the connecting end <NUM>. As shown in <FIG>, the connecting plane <NUM> of the connecting end <NUM> abuts against the photovoltaic module <NUM>. Along the first direction X, a width L of the connecting plane <NUM> satisfies: <NUM>≤L≤<NUM>. The width of the connecting plane <NUM> may be <NUM>, <NUM>, or <NUM>.

In some embodiments, if the width of the connecting plane <NUM> is small (i.e., L<<NUM>), a contact surface between the connecting end <NUM> and the photovoltaic module <NUM> is small. When the photovoltaic module <NUM> collapses downward along the second direction Y, a contact part between the photovoltaic module <NUM> and the connecting end <NUM> is prone to damages. If the width of the connecting plane <NUM> is large (i.e., L><NUM>), the connecting end <NUM> is of a large size, so that the mounting space of the connecting end <NUM> is increased and costs of the support portion are increased. Therefore, <NUM>≤L≤<NUM> can reduce the risk of damages caused by local force on the photovoltaic module <NUM> and reduce the space required by the mounting of the connecting end <NUM>.

In some embodiments, the width L of the connecting plane <NUM> satisfies: <NUM>≤L≤<NUM>. The width L of the connecting plane <NUM> may be <NUM>, <NUM>, or <NUM>, to reduce the risk of damages caused by local force on the photovoltaic module <NUM> and further reduce the size of the connecting plane <NUM>.

In some embodiments, as shown in <FIG>, the photovoltaic module <NUM> and/or the connecting end <NUM> is provided with a partition plate <NUM>. After the photovoltaic module <NUM> is fixedly connected to the color steel tile <NUM>, the partition plate <NUM> has one end abutting against the photovoltaic module <NUM> and the other end abutting against the connecting plane <NUM> of the connecting end <NUM>, that is, the photovoltaic module <NUM> is connected to the connecting plane <NUM> through the partition plate <NUM>. The risk of damages to the photovoltaic module <NUM> caused by direct contact of the connecting end <NUM> with the photovoltaic module <NUM> is reduced, thereby improving operation stability of the photovoltaic module <NUM> and prolonging the service life of the photovoltaic module <NUM>.

Along the third direction, a length of the partition plate <NUM> is the same as that of the photovoltaic module <NUM>, so as to increase support and protection effects of the partition plate <NUM> on the photovoltaic module <NUM>. Alternatively, one photovoltaic module <NUM> is provided with a plurality of partition plates <NUM>. The number of the partition plates <NUM> may be <NUM> to <NUM>. In some embodiments, <NUM> to <NUM> partition plates <NUM> are provided to simplify the operation of mounting the partition plates <NUM> and reduce the time required by the mounting of the partition plates <NUM>. When a plurality of partition plates <NUM> are provided and the plurality of partition plates <NUM> disposed on the photovoltaic module <NUM> at intervals, the partition plates <NUM> each have a length ranging from <NUM> to <NUM> along the third direction. The partition plates <NUM> each have a length ranging from <NUM> to <NUM>, to facilitate machining and mounting of the partition plates <NUM>.

In addition, the width of the partition plate <NUM> along the first direction X is no less than the width of the connecting plane <NUM>, which reduces the size of the connecting end <NUM> and increases a contact area of the photovoltaic module <NUM> and the partition plate <NUM>, thereby improving operation stability of the connecting end <NUM>, and reduces the risk of damages caused by local force on the photovoltaic module <NUM>, thereby further prolonging the service life of the photovoltaic module <NUM>.

In addition, as shown in <FIG>, the photovoltaic tile further includes a fixing device <NUM>. The photovoltaic module <NUM> is mounted on the folding portion <NUM> through the fixing device <NUM>, to simplify a manner of connecting the photovoltaic module <NUM> and the folding portion <NUM> and reduce the number of parts required when the photovoltaic module <NUM> is mounted on the folding portion <NUM>, thereby reducing the mounting space of the photovoltaic module <NUM> and increasing space utilization of the color steel pile <NUM>.

Along the third direction, a plurality of fixing devices <NUM> are provided, and the plurality of fixing devices <NUM> are evenly distributed on an edge of the photovoltaic module <NUM>.

In this embodiment, when the photovoltaic module <NUM> is connected to the fixing devices <NUM>, the fixing devices <NUM> may exert force on the photovoltaic module <NUM>, and the even distribution of the fixing devices <NUM> causes the photovoltaic module <NUM> to be stressed evenly, which reduces the risk of deformation and damages caused by local force on the photovoltaic module <NUM>, thereby improving operation stability of the photovoltaic module <NUM> and prolonging the service life of the photovoltaic module <NUM>.

The number N of the fixing devices <NUM> on one photovoltaic module <NUM> satisfies: <NUM>≤N≤<NUM>.

In some embodiments, <NUM>≤N≤<NUM>. After the photovoltaic module <NUM> is connected to the fixing devices <NUM>, along the second direction Y, a top surface of the photovoltaic module <NUM> away from the color steel tile <NUM> may carry a load with pressure greater than <NUM> Pa, and a bottom surface of the photovoltaic module <NUM> towards the color steel tile <NUM> may carry a load with pressure greater than <NUM> Pa. Therefore, if the number of the fixing devices <NUM> is no less than four (i.e., <NUM>≤N), stability of the connection between the fixing devices <NUM> and the photovoltaic module <NUM> is increased. If the number of the fixing devices <NUM> is no less than twelve (i.e., N≤<NUM>), the number of the fixing devices <NUM> is reduced, thereby reducing the space of the color steel tile <NUM> occupied by the mounting of the fixing devices <NUM>, reducing overall weight of the photovoltaic tile, and increasing scenarios to which the photovoltaic tile is applicable.

A specific structure of the fixing device <NUM> is shown in <FIG> and <FIG>. The fixing device <NUM> includes a first clamping portion <NUM> configured to clamp the folding portion <NUM> and a second clamping portion <NUM> configured to clamp the photovoltaic module <NUM>. The fixing device <NUM> is provided with both the first clamping portion <NUM> and the second clamping portion <NUM>, that is, the fixing device <NUM> can implement the function of simultaneously clamping the color steel tile <NUM> and the photovoltaic module <NUM>, so as to mount the photovoltaic module <NUM> to a building such as a rooftop.

In the related art, a large number of purlins are adopted in a rooftop photovoltaic power station of the color steel tile <NUM>, the purlins are fixed to the rooftop of a building, the color steel tile <NUM> is mounted on the purlins through a fixture, and the photovoltaic module <NUM> is generally mounted on the purlins through a block pressing means. In this mounting manner, a large number of purlins, fixtures, block pressing means, etc. are required, thereby increasing material costs. At the same time, in this mounting manner, procedures are complicated, and labor costs are increased. In the present disclosure, the fixing device <NUM> is integrated with the first clamping portion <NUM> and the second clamping portion <NUM>, so that the fixing device <NUM> can simultaneously clamp the photovoltaic module <NUM> and the color steel tile <NUM>, and then the photovoltaic module <NUM> can be mounted on the color steel tile <NUM> through the fixing device <NUM>. This mounting manner helps to reduce the use of purlins and other devices, thereby helping to reduce material and labor costs.

The fixing device <NUM> in the embodiments of the present disclosure can provide large clamping force on the photovoltaic module <NUM>, and is suitable for the photovoltaic module <NUM> with a large size, such as the <NUM> photovoltaic module <NUM>, so as to help to improve reliability of the clamping of the photovoltaic module <NUM> with a large size and further improve the stability of the mounting of the photovoltaic module <NUM>.

In some embodiments, as shown in <FIG>, the first clamping portion <NUM> includes a first clamping body <NUM> and a second clamping body <NUM> arranged opposite to each other along the first direction X. The first clamping body <NUM> and the second clamping body <NUM> can clamp the folding portion <NUM>, so that the fixing device <NUM> is mounted on the folding portion <NUM>.

The fixing device <NUM> clamps the folding portion <NUM> through the first clamping body <NUM> and the second clamping body <NUM>, which simplifies the manner of connecting the fixing device <NUM> and the folding portion <NUM>, simplifies the structure of the fixing device <NUM>, reduces the size of the fixing device <NUM>, reduces manufacturing costs of the fixing device <NUM>, and reduces the space required by the mounting of the fixing device <NUM>, thereby increasing space utilization of the color steel tile <NUM>.

In some embodiments, as shown in <FIG> and <FIG>, the first clamping body <NUM> includes a first bending structure 411a, the second clamping body <NUM> includes a second bending structure 412a, and the first bending structure 411a and the second bending structure 412a define a first clamping space <NUM>. As shown in <FIG>, the folding portion <NUM> includes a first sidewall <NUM> and a second sidewall <NUM> arranged opposite to each other along the first direction X. When the fixing device <NUM> is connected to the folding portion <NUM>, a part of the folding portion <NUM> is located in the first clamping space <NUM>, the first sidewall <NUM> abuts against the first bending structure 411a, and the second sidewall <NUM> abuts against the second bending structure 412a. At the same time, an outer contour of the first bending structure 411a matches the first sidewall <NUM>, and an outer contour of the second bending structure 412a matches the second sidewall <NUM>, so as to improve stability of connection between the first clamping body <NUM> and the first sidewall <NUM> and between the second clamping body <NUM> and the second sidewall <NUM>.

The first fastener <NUM> may be a screw, a bolt, or other connection structures. The specific type and structure of the first fastener <NUM> are not specially limited in the present disclosure.

When the first fastener <NUM> is not fixedly connected to the first extension portion 411b and the second extension portion 412b, the first extension portion 411b and the second extension portion 412b can elastically deform along the first direction X. In this case, the first clamping body <NUM> can move along the first direction X to a direction away from the second clamping body <NUM>. The second clamping body <NUM> can move along the first direction X to a direction away from the first clamping body <NUM>, so that the first clamping space <NUM> is increased, so as to facilitate extension of a part of the folding portion <NUM> into the first clamping space <NUM>. When the first fastener <NUM> is fixedly connected to the first extension portion 411b and the second extension portion 412b, the first clamping body <NUM> and the second clamping body <NUM> cannot move along the first direction X, so as to clamp the folding portion <NUM>, so that the fixing device <NUM> is fixedly connected to the folding portion <NUM>. Thus, the arrangement of the first fastener <NUM> simplifies operations of mounting and disassembling the fixing device <NUM> on the folding portion <NUM>, and simplifies the structure of the first clamping portion <NUM>, thereby simplifying the structure of the fixing device <NUM>.

At the same time, the first extension portion 411b and the second extension portion 412b play a role in elevating the second clamping portion <NUM>, thereby reducing the possibility of interference between the photovoltaic module <NUM> and the male rib <NUM> and the female rib <NUM> of the color steel tile <NUM> when the second clamping portion <NUM> clamps the photovoltaic module <NUM>.

As shown in <FIG> and <FIG>, the first clamping body <NUM> includes a third extension portion 411c, the third extension portion 411c is located at the end of the first bending structure 411a close to the color steel tile <NUM>. That is, the third extension portion 411c is located at the end of the first bending structure 411a away from the first extension portion 411b, and has a preset angle with the first bending structure 411a. The second clamping body <NUM> includes a fourth extension portion 412c, the fourth extension portion 412c is located at the end of the second bending structure 412a close to the color steel tile <NUM>. That is, the fourth extension portion 412c is located at the end of the second bending structure 412a away from the second extension portion 412b, and has a preset angle with the second bending structure 412a. The third extension portion 411c and the fourth extension portion 412c are both configured to abut against the color steel tile <NUM>.

When the first clamping portion <NUM> clamps the folding portion <NUM>, both the third extension portion 411c and the fourth extension portion 412c can abut against a sidewall of the color steel tile <NUM>, so as to help to improve stability of the mounting between the fixing device <NUM> and the color steel tile <NUM> and help to implement the clamping effect of the first clamping portion <NUM> on the folding portion <NUM>, thereby helping to improve the reliability of the connection between the folding portion <NUM> and the first support <NUM>.

Along the first direction X, the fixing device <NUM> is provided with one second clamping portion <NUM>, so that the fixing device <NUM> can clamp one photovoltaic module <NUM>. Alternatively, the fixing device <NUM> is provided with two second clamping portions <NUM>, and the two second clamping portions <NUM> are symmetrically arranged on two sides of the first clamping portion <NUM> along the first direction X, so that the fixing device <NUM> can simultaneously clamp two photovoltaic modules <NUM>.

In an embodiment, as shown in <FIG> and <FIG>, the second clamping portion <NUM> of the fixing device <NUM> is arranged on the first clamping body <NUM> and/or the second clamping body <NUM>, the second clamping portion <NUM> being provided with a first clip <NUM> and a second clip <NUM> arranged along the second direction Y, and the first clip <NUM> and the second clip <NUM> are configured to clamp the photovoltaic module <NUM>.

The fixing device <NUM> clamps the photovoltaic module <NUM> through the first clip <NUM> and the second clip <NUM>, which simplifies the manner of connecting the fixing device <NUM> and the photovoltaic module <NUM>, simplifies the structure of the fixing device <NUM>, reduces the size of the fixing device <NUM>, reduces manufacturing costs of the fixing device <NUM>, and reduces a space required by the mounting of the fixing device <NUM>, thereby increasing the space utilization of the color steel tile <NUM>.

As shown in <FIG> and <FIG>, the fixing device <NUM> further includes a second fastener <NUM>, and the first clip <NUM> is connected to the second clip <NUM> through the second fastener <NUM>. The second fastener <NUM> may be a screw, a bolt, or other connection structures. The specific type and structure of the second fastener <NUM> are not specially limited in the present disclosure.

When the second fastener <NUM> is not fixedly connected to the first clip <NUM> and the second clip <NUM>, the first clip <NUM> can move along the second direction Y to a direction away from the second clip <NUM>, so as to increase the size of the second clamping space <NUM> between the first clip <NUM> and the second clip <NUM>, thereby facilitating extension of a part of the photovoltaic module <NUM> into the second clamping space <NUM>. When the second fastener <NUM> is fixedly connected to the first clip <NUM> and the second clip <NUM>, the first clip <NUM> cannot move along the second direction Y, so as to clamp the photovoltaic module <NUM>, so that the fixing device <NUM> is fixedly connected to the photovoltaic module <NUM>. Thus, the arrangement of the second fastener <NUM> simplifies operations of mounting and disassembling the fixing device <NUM> on the photovoltaic module <NUM>, and simplifies the structure of the second clamping portion <NUM>, thereby simplifying the structure of the fixing device <NUM>.

As shown in <FIG>, the first clip <NUM> includes a first limit portion 431a, the first limit portion 431a extends towards a direction close to the second clip <NUM>, the first limit portion 431a is provided with a first protrusion 433a portion 431b, the second clip <NUM> is provided with a groove 432a, and a sidewall on at least one side of the groove 432a is provided with a second protrusion 433a portion 432b. When the second clamping portion <NUM> clamps the photovoltaic module <NUM>, the first protrusion 433a portion 431b can abut against the second protrusion 433a portion 432b to limit the position of the first clip <NUM>.

When the second clamping portion <NUM> clamps the photovoltaic module <NUM>, the first clip <NUM> may move relative to the second clip <NUM>. When the first protrusion 433a portion 431b can match with the second protrusion 433a portion 432b, the first clip <NUM> cannot continue moving towards a direction away from the second clip <NUM>, so as to limit the position of the first clip <NUM>, thereby reducing the possibility of falling off of the first clip <NUM> from the fixing device <NUM>. In some embodiments, the groove 432a may be provided with the second protrusion 433a portion 432b on two sides, and the first clip <NUM> is provided with two first limit portions 431a, so as to further limit the position of the first clip <NUM>.

As shown in <FIG>, the first clip <NUM> includes a second limit portion 431c. When the second clamping portion <NUM> clamps the photovoltaic module <NUM>, along the second direction Y, a bottom wall of the second limit portion 431c can abut against a top wall of the groove 432a to limit the position of the first clip <NUM>.

When the first clip <NUM> moves close to the second clip <NUM>, the second limit portion 431c can limit the position of the first clip <NUM>. That is, when the second limit portion 431c abuts against the top wall of the groove 432a, the second limit portion 431c cannot continue moving towards a direction close to the second clip <NUM>. Such arrangement also helps to improve the stability of the mounting of the first clip <NUM> while limiting the position of the first clip <NUM>.

As shown in <FIG>, a first cushioning member 431d is mounted on the first clip <NUM>, and a second cushioning member 432c is mounted on the second clip <NUM>. After the photovoltaic module <NUM> is connected to the second clamping portion <NUM>, the first clip <NUM> and the second clip <NUM> clamp the photovoltaic module <NUM> through the first cushioning member 431d and the second cushioning member 432c, which reduces the risk of abrasion of and damages to the photovoltaic module <NUM> caused by direct contact of the first clip <NUM> and the second clip <NUM> with the photovoltaic module <NUM>, ensures stability of the mounting of the photovoltaic module, improves operation stability of the photovoltaic module <NUM>, and prolongs the service life of the photovoltaic module.

As shown in <FIG>, a plurality of protrusions 433a are successively arranged on a top wall and a bottom wall of the second clamping space <NUM>. The protrusions 433a are configured to abut against the photovoltaic module <NUM>.

A plurality of protrusions 433a being successively arranged on a top wall and a bottom wall of the second clamping space <NUM>, that is, a plurality of successive protrusions 433a are arranged on the sides of the first cushioning member 431d and the second cushioning member 432c abutting against the photovoltaic module <NUM>. Such arrangement helps to improve friction between the first cushioning member 431d, the second cushioning member 432c and the photovoltaic module <NUM>, thereby helping to improve stability of the clamping of the second clamping portion <NUM> and improving stability of the mounting of the photovoltaic module <NUM>.

As shown in <FIG>, the support includes a first support <NUM>. The first support <NUM> has one end fixedly connected to the roof and the other end located on the folding portion <NUM> of the color steel tile <NUM> to mount the color steel tile <NUM> on the roof. The first support <NUM> includes a bending portion <NUM> and a first mounting portion <NUM>. The bending portion <NUM> may extend into the folding portion <NUM>. For example, the bending portion <NUM> can match with the folding portion <NUM>, that is, the bending portion <NUM> can abut against an inner wall of the folding portion <NUM>, so as to help to improve the reliability of connection between the folding portion <NUM> and the first support <NUM> and reduce the possibility of falling off the bending portion <NUM> from the folding portion <NUM>. Two ends of the bending portion <NUM> may be connected to the first mounting portion <NUM>, and the first mounting portion <NUM> is connected to the roof by threading, so that the first support <NUM> is fixed to the roof and then the color steel tile <NUM> can be connected to the roof through the first support <NUM>. The first support <NUM> has one end fixedly connected to the roof through a screw and the other end extending into the folding portion <NUM>. Under the action of the fixing device <NUM> of the color steel tile <NUM>, the folding portion <NUM> may be located in the first clamping space <NUM>. Therefore, the first clamping portion <NUM> may clamp the first support <NUM> and the folding portion <NUM>, that is, strengthen and fix the connection between the first support <NUM> and the folding portion <NUM>, so as to improve stability and reliability of the connection.

In the related art, the stability of the connection between the color steel tile <NUM> and the support is low, and the color steel tile <NUM> has poor wind drag performance. As a result, the color steel tile <NUM> is easily detached from the roof under wind pressure, which cannot be used normally and brings safety risk. Compared with the related art, in the embodiments of the present disclosure, through the clamping of the fixing device <NUM>, the joint between the color steel tile <NUM> and the first support <NUM> is fixed and strengthened. That is, the stability of the connection between the folding portion <NUM> and the first support <NUM> is strengthened, so that the connection is firmer, thereby helping to improve wind drag performance of the color steel tile <NUM> and helping to improve security of use.

As shown in <FIG> and <FIG>, the support includes a second support <NUM>. The second support <NUM> has one end fixedly connected to the connecting end <NUM> of the color steel pile <NUM> and the other end fixedly connected to the roof to mount the color steel tile <NUM> on the roof. The second support <NUM> includes a fixing bracket <NUM> and a second mounting portion. The fixing bracket <NUM> includes a main body portion <NUM>, a first extension end <NUM>, and a second extension end <NUM>. The main body portion <NUM> has one end connected to the first extension end <NUM> and the other end connected to the second extension end <NUM>. The first extension end <NUM> can abut against an inner wall of the color steel tile <NUM>, which helps to support the color steel tile <NUM>. The second extension end <NUM> can be connected to the roof by threading, so as to fix the second support <NUM> to the roof. The second mounting portion has one end connected to the fixing bracket <NUM> and the other end connected to the male rib <NUM> and the female rib <NUM> by overlocking. The main body portion <NUM> is provided with a chute <NUM>, and a matching slot <NUM> of the second mounting portion <NUM> can match with a sidewall of the chute <NUM> and slide along the chute <NUM>. That is, the second mounting portion is connected to the fixing bracket <NUM> through the matching slot <NUM>, and the sidewall of the chute <NUM> can extend into the matching slot <NUM>. The second mounting portion <NUM> is provided with two matching slots <NUM>. The two matching slots <NUM> match with sidewalls on two sides of the chute <NUM> respectively. When the color steel tile <NUM> is affected by an ambient temperature and leads to deformation, the color steel tile <NUM> can slide relative to the chute <NUM> through the second mounting portion <NUM>, so as to help to compensate the stress caused by the deformation of the color steel tile <NUM> and reduce the possibility of damages to the color steel tile <NUM>, thereby helping to prolong the service life of the color steel tile <NUM>.

Through joint crimping of the male rib <NUM> and the female rib <NUM>, the male rib <NUM> and the female rib <NUM> are connected to each other, so that the adjacent color steel tiles <NUM> are connected and the connecting end can support the photovoltaic module <NUM>.

In S2, the fixing devices <NUM> are on adjacent folding portions <NUM> respectively. The fixing devices <NUM> are mounted on the folding portions <NUM> by clamping, and the clamping of the fixing devices <NUM> with the folding portions <NUM> can improve strength of folding, thereby improving overall wind drag performance of the color steel tile <NUM>.
