At present, the application field of photovoltaic power generation is extensive, and the integrated design of solar energy and buildings (BIPV) has gradually become a trend. The residential roof is the main application area of distributed photovoltaics. In related technologies, when photovoltaic tiles are laid on the roof, a gap is formed between the photovoltaic tiles and the roof surface, which causes some small animals such as insects and mice to enter the roof and generate garbage and peculiar smells. Content of the Utility Model

[0003] The utility model provides a photovoltaic roof system.

[0004] The photovoltaic roof system of the embodiment of the present application includes photovoltaic tiles and an insect-proof net. The photovoltaic tiles are arranged on the roof, and the insect-proof net is connected between the photovoltaic tiles and the roof surface of the roof. The insect-proof net, the photovoltaic tiles and the roof surface form a closed cavity.

[0005] In this way, the gap between the photovoltaic tiles and the roof is surrounded and closed by the insect-proof net, which can prevent small animals from entering the roof to generate garbage and peculiar smells, and damage the cables of the photovoltaic tiles. At the same time, the insect-proof net can ventilate, which is convenient for the photovoltaic tiles to dissipate heat during use, thereby improving the power generation efficiency of the photovoltaic tiles and reducing indoor energy consumption.

[0006] In some embodiments, a mounting rack is arranged on the roof, the photovoltaic tiles are mounted on the mounting rack, and the insect-proof net is connected to the mounting rack.

[0007] In this way, the mounting rack can provide support for the photovoltaic tiles and the insect-proof net, which is convenient for installing the photovoltaic tiles and the insect-proof net, and makes the installation of the photovoltaic tiles and the insect-proof net convenient.

[0008] In some embodiments, the mounting rack includes a support member and a mounting member arranged crosswise with the support member. The photovoltaic tiles are placed on the mounting member, and the support member and / or the mounting member penetrate through the insect-proof net.

[0009] In this way, the support member can provide support for the mounting member and the insect-proof net, which is convenient for installing the photovoltaic tiles and the insect-proof net, and makes the installation of the photovoltaic tiles and the insect-proof net convenient.

[0010] In some embodiments, the support member is fixed on the roof surface along a direction perpendicular to the eaves, and the mounting member is vertically arranged on the support member.

[0011] In this way, the support member is fixed on the roof surface in a direction perpendicular to the eaves, so that the rainwater entering the roof can flow down along the support member from the eaves. The installation member is arranged on the support member, which can prevent the installation member from blocking the flow of rainwater and causing the rainwater to accumulate on the roof, resulting in peculiar smell and corrosion of the roof, thereby improving the service life of the roof. At the same time, a gap is formed between the installation member and the roof surface, and the heat generated during the use of the photovoltaic tile can be dissipated from the insect-proof net through the gap.

[0012] In some embodiments, the number of support members is multiple, and the multiple support members are arranged at intervals; and / or, the number of installation members is multiple, and the multiple installation members are arranged at intervals.

[0013] In this way, the multiple support members and the multiple installation members can provide multiple supports for the photovoltaic tile, thereby improving the installation stability of the photovoltaic tile.

[0014] In some embodiments, the insect-proof net includes a first bending portion and a second bending portion. The first bending portion is fixedly connected to the roof surface, and the second bending portion is penetrated through the support member and / or the installation member and connected to the photovoltaic tile.

[0015] In this way, the insect-proof net can be fixed on the roof surface and the mounting rack through the first bending portion and the second bending portion, and a closed cavity is formed by the insect-proof net, the photovoltaic tile and the roof surface.

[0016] In some embodiments, the edge of the second bending portion connected to the photovoltaic tile fits the surface of the photovoltaic tile.

[0017] In this way, it is possible to prevent a gap from being formed at the connection between the second bending portion and the photovoltaic tile, thereby preventing small animals from entering the roof through the gap.

[0018] In some embodiments, a sealant is provided at the connection between the second bending portion and the support member and / or the installation member.

[0019] In this way, the sealant can block the gap formed at the connection between the second bending portion and the support member and / or the installation member, thereby preventing small animals from entering the roof through the gap.

[0020] In some embodiments, the second bending portion is inclined with respect to the first bending portion.

[0021] In this way, it is possible to prevent the photovoltaic tile from squeezing the second bending portion and causing the second bending portion to tilt to both sides, resulting in a gap at the edge where the second bending portion is in partial contact with the photovoltaic tile, thereby preventing small animals from entering the roof through the gap.

[0022] In some embodiments, a drip tile is provided on the roof, and the drip tile is arranged on the side of the support member protruding from the eaves.

[0023] In this way, the drip tile can centrally guide rainwater, allowing the rainwater to vertically drip onto the ground and preventing the rainwater from infiltrating back to the bottom of the photovoltaic tile near the eaves due to capillary action. At the same time, the drip tile can seal the gap between the photovoltaic tile and the mounting member to prevent rainwater from being blown into the gap.

The photovoltaic tiles 10 are arranged on the roof 30, and the insect-proof net 20 connects the photovoltaic tiles 10 and the roof surface 31 of the roof 30. The insect-proof net 20, the photovoltaic tiles 10, and the roof surface 31 form a closed cavity.

[0037] In this way, by surrounding and closing the gap between the photovoltaic tiles 10 and the roof 30 with the insect-proof net 20, small animals can be prevented from entering the roof 30 to generate garbage and odors, and damage to the cables of the photovoltaic tiles 10 can be avoided. At the same time, the insect-proof net 20 can ventilate, facilitating the heat dissipation of the photovoltaic tiles 10 during use, thereby improving the power generation efficiency of the photovoltaic tiles 10 and reducing indoor energy consumption.

[0038] Specifically, the photovoltaic tile 10 is a roof tile that can convert solar energy into electrical energy. The photovoltaic tile 10 can be additionally installed on the existing roof surface 31 or used as a building component, that is, for photovoltaic building integration applications. The photovoltaic tile 10 can be a flat tile or a curved tile, and the photovoltaic tile 10 can be applied to flat or vertical installations.

[0039] The insect-proof net 20 is a mesh fabric made of polyethylene with chemical additives such as anti-aging and anti-ultraviolet agents as the main raw material and manufactured by wire drawing.

[0040] Please refer to Figure 1 and Figure 2 , in some embodiments, an installation frame 40 is arranged on the roof 30, the photovoltaic tile 10 is installed on the installation frame 40, and the insect-proof net 20 is connected to the installation frame 40.

[0041] Thus, the mounting frame 40 can provide support for the photovoltaic tile 10 and the insect-proof net 20, facilitating the installation of the photovoltaic tile 10 and the insect-proof net 20, and making the installation of the photovoltaic tile 10 and the insect-proof net 20 convenient.

[0042] Specifically, the mounting frame 40 can be a bracket made of metal materials, including but not limited to aluminum, stainless steel, etc. The mounting frame 40 can be fixed to the roof surface 31 by welding or mechanical means.

[0043] Please refer to Figure 1 and Figure 2 , in some embodiments, the mounting frame 40 includes a support member 41 and a mounting member 42 arranged crosswise with respect to the support member 41. The photovoltaic tile 10 is placed on the mounting member 42, and the support member 41 and / or the mounting member 42 penetrates through the insect-proof net 20.

[0044] Thus, the support member 41 can provide support for the mounting member 42 and the insect-proof net 20, facilitating the installation of the photovoltaic tile 10 and the insect-proof net 20, and making the installation of the photovoltaic tile 10 and the insect-proof net 20 convenient.

[0045] Specifically, the support member 41 and the mounting member 42 can be rectangular long strips, and the included angle formed between the support member 41 and the mounting member 42 can be a right angle, an acute angle or an obtuse angle.

[0047] Perforations are formed on the insect-proof net 20, and the shape and size of the perforations can be the same as the cross-sectional shape and size of the support member 41 and the mounting member 42, so that the insect-proof net 20 is penetrated on the support member 41 and the mounting member 42 and is attached to the outer walls of the support member 41 and the mounting member 42. All of the insect-proof net 20 can be penetrated on the support member 41, or all of the insect-proof net 20 can be penetrated on the mounting member 42, or part of the insect-proof net 20 can be penetrated on the support member 41 while part of the insect-proof net 20 is penetrated on the mounting member 42.

[0057] Specifically, the first bending portion 21 and the second bending portion 22 can be integrally formed, or can be connected by welding, buckling or mechanical connection. The first bending portion 21 can be fixed on the roof surface 31 by fasteners such as screws.

[0058] Please refer to Figure 1 and Figure 2 In some embodiments, as shown in FIGS. and, the edge of the second bending portion 22 connected to the photovoltaic tile 10 is attached to the surface of the photovoltaic tile 10.
