In FIG. 1, due to the limitation of expression, the configuration of the sub protrusion 152a and the sub concave portion 151a to be described later is not shown, and this is shown through FIG. That is, some drawings for explaining the present embodiment have been shown to be exaggerated or omitted so that the structure may be more easily understood.

A roofing material including a solar panel includes a frame 100, a solar panel 200 coupled to an upper portion of the frame 100, and a structure for fixing the solar panel 200 to the frame 100. The top 300 and a sealing part 400 that seals between the frame 100 and the solar panel 200 to prevent leakage, and the frame 100 from the outside of the solar panel 200 And a stone chip 500 attached to the upper part of the sealing part 400.

The frame 100 may be made of metal, and may be made of metal such as galvalume, galvanized steel sheet (GI), aluminum (Al), and zinc. The thickness of the metal may be at least 0.4mm or more. If the metal is too thin, the solar panel cannot be safely supported, and damage to the solar panel may occur during the roof construction process.

The frame 100 includes a main cover part 110 and a first bending part 120 bent upward in a first direction (x-axis direction) of the main cover part, and a lower part in the other side of the first direction of the main cover part. It includes a second bending portion 130 bent toward. That is, the first bending portion 110 and the second bending portion 120 may be provided at both ends of the frame 100 in the first direction.

Here, the first bending part 120 is located above the slope of the roof to be constructed, and the second bending part 130 is located below the slope of the roof being constructed. The first bending part 120 includes an upper and lower extension part 121 extending upward from one end of the main cover part 100 in the first direction, and an outer side in the first direction from the upper end of the upper and lower extension part 121. It includes a horizontal extension portion 122 extending toward. However, the shapes of the first bending portion 120 and the second bending portion 130 are not limited thereto, and the shape is not limited.

At least one or more of the first bending portion 120 and the second bending portion 130 may have a corrugation extending in the vertical direction. In addition, at least one or more of the vertical extension portion 121 or the horizontal extension portion 122 of the first bending portion 120 may be corrugated. When the wrinkles are formed in the upper and lower extension portions 121, the wrinkles are elongated in the vertical direction (z-axis direction), and when the wrinkles are formed in the horizontal extension portion 122, the wrinkles are along the first direction. Extends long

Meanwhile, the frame 100 further includes side overlapping portions 141 and 142 provided on both sides of the main cover portion 110 in the second direction (y-axis direction). Here, the second direction is a direction crossing the first direction. For example, it may be a direction orthogonal to the first direction. Since the roofing material including the solar panel according to the present invention is formed longer in the second direction, the second direction becomes a length direction.

The side overlapping parts 141 and 142 include a first side overlapping part 141 located on one side of the main cover part 110 in the second direction, and a second side overlapping part 142 located on the other side of the second direction. Includes. Since the roofing material including the solar panel according to the present invention is formed longer in the second direction, the second direction may be a length direction. The side overlapping portions 141 and 142 may be provided at both ends of the frame 100 in the second direction. The first side overlapping portion 141 and the second side overlapping portion 142 have corresponding shapes to overlap each other. More precisely, when a plurality of roofing members are installed, the first side overlapping portion 121 of one roofing member and the second side overlapping portion 122 of another adjacent roofing member overlap each other in the second direction. .

On the other hand, the frame 100 is provided on the main cover portion 110, and includes a panel support portion 150 for supporting the solar panel 200 positioned at the top from the bottom. Accordingly, the solar panel 200 is coupled to the upper portion of the panel support 150. The panel support part 150 may be positioned between the first side overlapping part 141 and the second side overlapping part 142.

The panel support 150 includes a plurality of main protrusions 151 and a plurality of main recesses 152. One main protrusion 151 and the other main protrusion 151 are located spaced apart from each other, and a main concave part 152 is positioned between them. In this case, the panel support 150 includes a plurality of main concave portions 152, and the main protrusion 151 is located in a space spaced apart between the main concave portions 152.

The main protrusion 151 supports the solar panel from below. In more detail, the solar panel and the fixing part 300 to be described later are in contact with each other and supported therebetween.

Meanwhile, the solar panel 200 to be described later includes a plurality of solar cells 201 (SOLAR CELL) arranged along the second direction, and the structure of the solar panel 200 will be described again later.

At least one main protrusion 151 is positioned under each of the plurality of solar cells 201. Therefore, even if an operator steps on the solar panel from the top, the main protrusion 151 from the bottom of each solar cell supports each solar cell 121, so that any one solar cell is excessively bent and damaged. Can be prevented.

Meanwhile, a plurality of main protrusions 151 may be provided under each solar cell. In this case, if at least one of the plurality of main protrusions is disposed in the left and right sides from the center in the second direction of the corresponding solar cell, the solar cell can be more effectively supported. In this case, a main concave portion 152 is disposed under each solar cell.

The main protrusion 151 and the main concave portion 152 may extend long along the first direction. In this case, the lengths of the main protrusions 151 and the main concave portions 152 in the first direction are longer than the lengths in the first direction of the solar cell 201 to be described later. Accordingly, both ends of the main protrusion 151 in the first direction may be located outside both ends of the solar cell 201 in the first direction. In this way, the entire solar cell can be supported by the main protrusion along the first direction.

Meanwhile, when a plurality of solar cells 201 are disposed along the first direction, the length of the main protrusion 151 has a length capable of covering all of the plurality of solar cells along the first direction. That is, one end of the main protrusion 151 is located closer to the first bending part than the solar cell located on the first bending part 120 side, and the other end is more than a solar cell located on the second bending part 130 side. It is located closer to the side of the second bending part.

Meanwhile, a sub-concave portion 151a may be provided in the main protrusion 151. The sub-concave portion 151a is provided such that a part of the main protrusion 151 is formed to be concave downward. The depth of the sub-concave part 151a is smaller than that of the main concave part 152. The width of the sub-concave portion 151a in the second direction is smaller than that of the corresponding main protrusion 151 in which the sub-concave portion is located.

Meanwhile, a sub protrusion 152a may be provided in the main concave portion 152. The height of the upper end of the sub protrusion 152a is lower than the upper end of the main protrusion 121. The width of the sub-protrusion 152a in the second direction is smaller than the corresponding main concave part 152 located at the sub-protrusion.

With such a structure, a plurality of main protrusions 151, main concave portions 152, sub concave portions 151a, and sub protrusions 152a can increase the support strength against external force from the upper side, It is possible to prevent the occurrence of micro-cracks or the like due to deformation of the solar cell.

In addition, the sub-concave portion 151a and the sub-protrusion 152a may be more effective in discharging heat generated from the solar cell during solar power generation by increasing the cross-sectional area of the panel support portion 150.

On the other hand, the main cover portion 110 is provided with a cutout (not shown) that is perforated up and down. The cut-out portion is a portion through which the electric wires and terminals of the solar panel 200 to be described later pass, and a junction box (not shown) is positioned below the cut-out portion.

The solar panel 200 must be disposed so as not to overlap with at least one of the side overlapping portions 141 and 142. This is because when the solar panel overlaps the overlapping portions on both sides, one roofing material and another roofing adjacent to each other cannot be constructed by overlapping each other.

Meanwhile, the frame 100 may be integrally formed by pressing one metal member. However, for more accurate shape processing before press processing, pre-treatment of the metal member may be performed. For example, after forming a corrugation on a metal sheet, press processing may be performed.

Hereinafter, the solar panel 200 will be described with reference to FIGS. 1 and 2.

The solar panel 200 includes a solar cell 201 that generates electricity by receiving sunlight, a protection unit 202 positioned above the solar cell 201, and the solar cell 201.

The roofing material including the solar panel according to an embodiment of the present invention further includes a fixing part 300.

The fixing part 300 serves to fix the solar panel 200 to the metal frame 100. The fixing part 300 may be, for example, a double-sided tape or a double-sided adhesive sheet, but is not limited thereto.

The roofing material including the solar panel according to an embodiment of the present invention further includes a sealing part 400. The sealing part 400 serves to prevent leakage between the frame 100 and the solar panel 200. The sealing part 400 is provided along the edge of the solar panel 200. For example, the sealing part 400 may be silicon. Since the sealing part 400 is filled between the main concave part 152 and the sub concave part 151a, the adhesion area between the frame 100 and the sealing part 400 is increased, thereby increasing the adhesion. Meanwhile, the sealing part 400 is shown by a dotted line, because a stone chip 500, which will be described later, is attached to the upper portion thereof, so that the sealing part 400 is not exposed to the outside.

The roofing material including the solar panel according to an embodiment of the present invention further includes a stone chip 500. The stone chip 500 is attached to the upper part of the frame 100 and the sealing part 400 so that the upper surfaces of the frame 100 and the sealing part 400 are not directly exposed to the outside. Accordingly, by blocking exposure of the frame 100 and the sealing unit 400 to ultraviolet rays, the lifespan may be increased and durability may be increased. The stone chip 500 may be attached to an outer portion of the solar cell 201 so as not to interfere with power generation. In more detail, it may be attached to the outer portion of the solar panel 200. The stone chips 500 are made by crushing stones into small sizes, and the stones used here may be, for example, basalt. When the stone chip 500 is a small crushed black stone or colored black, the solar panel is not visually conspicuous, and a more visually natural roof can be made.

The stone chip 500 may be attached by an adhesive. The adhesive may be, for example, an acrylic water-based adhesive.

The main protrusion 151 supports the solar panel from below. In more detail, the solar panel and the fixing part 300 to be described later are in contact with each other and supported therebetween.

At least one main protrusion 151 is positioned under each of the plurality of solar cells 201. Therefore, even if the operator steps on the solar panel 200 from the top, since the main protrusion 151 from the bottom of each solar cell supports each solar cell 201, any one solar cell is excessively bent, It will be possible to prevent damage.

Meanwhile, a plurality of main protrusions 151 may be provided under each solar cell. In this case, if the plurality of main protrusions are disposed in the left and right sides from the center in the second direction of the corresponding solar cell, it is possible to more effectively support the solar cell. In this case, a main concave portion 152 is disposed under each solar cell.

The main protrusion 151 and the main concave portion 152 may extend long along the first direction. In this case, the lengths of the main protrusions 151 and the main concave portions 152 in the first direction are longer than the lengths in the first direction of the solar cell 201 to be described later. Accordingly, both ends of the main protrusion 151 in the first direction may be located outside both ends of the solar cell 201 in the first direction. In this way, the entire solar cell can be supported by the main protrusion along the first direction.

Meanwhile, when a plurality of solar cells 201 are disposed along the first direction, the length of the main protrusion 151 has a length capable of covering all of the plurality of solar cells along the first direction. That is, one end of the main protrusion 151 is located closer to the first bending part than the solar cell located on the first bending part 120 side, and the other end is more than a solar cell located on the second bending part 130 side. It is located closer to the side of the second bending part.
