[0002] Building-integrated photovoltaics (BIPV) involves installing photovoltaic modules on the surface of a building's exterior envelope to provide electricity. These modules also function as a part of the building structure, replacing some traditional building components such as roof panels, tiles, windows, building facades, or awnings. BIPV modules can also be made into multifunctional building components to achieve more functions, such as photovoltaic thermal systems, integration with lighting, and building shading.
[0003] When snow and ice cover photovoltaic panels, they not only hinder sunlight absorption and reduce power generation efficiency, but also damage the equipment. To address this, some photovoltaic systems install electric heating cables on the panels. Electric heating is an effective snow removal method applicable to rooftop photovoltaic systems. It uses electrical energy to convert into heat energy, raising the surface temperature of the photovoltaic panels to prevent snow and ice accumulation. During installation, the heating cables are fixed to the photovoltaic panel frame using connectors. However, due to the gaps between adjacent heating cables and the difficulty in adjusting their position, localized snow accumulation may occur during snow removal, a problem that needs improvement.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes an electrically conductive photovoltaic module, including a support frame 3.

A photovoltaic panel 1 is laid on one side of the support frame 3, and the photovoltaic panel 1 is detachably connected to the support frame 3. The photovoltaic panel 1 is laid on the support frame 3 and is fixed to the support frame 3 in a detachable installation method, which facilitates the later maintenance of the photovoltaic panel 1.
[0025] The support frame 3 has a first guide 4 on one side and a second guide 5 on the other side. The first guide 4 and the second guide 5 are detachably connected to the fixed base 2. The first guide 4 and the second guide 5 are also fixed to the fixed base 2 in a detachable manner, which facilitates the assembly and disassembly of the guide and the electric heating tape 7.
[0026] An electric heating cable 7 is provided on the side of the photovoltaic panel 1 away from the support frame 3. A fixed frame 6 is fixedly installed on the outside of the electric heating cable 7. The left and right ends of the fixed frame 6 are slidably connected to the first guide member 4 and the second guide member 5, respectively. An adjustment device is provided on the first guide member 4 to drive the electric heating cable 7 to slide along the surface of the photovoltaic panel 1.
[0027] The electric heating cable 7 is a wire with a heating element. When snow accumulates on the photovoltaic panel 1, the electric heating cable 7 can provide stable heating power, effectively melting the snow and preventing damage to the photovoltaic panel caused by the snow. To ensure uniform temperature distribution on the surface of the photovoltaic panel, the adjustment device on the first guide 4 can drive the electric heating cable 7 and the fixing frame 6 to slide on the surface of the photovoltaic panel 1, ensuring that there is no snow residue on the photovoltaic panel. The first guide 4 and the second guide 5 limit the electric heating cable 7 from the left and right ends.
[0028] Regarding the first guide component 4:
[0029] The first guide member 4 includes a limiting cylinder 41 and first support columns 42 located at the left and right ends of the limiting cylinder 41. The upper end of the first support column 42 is fixedly connected to the limiting cylinder 41, and the lower end of the first support column 42 is detachably connected to the fixing seat 2. A first sliding sleeve 43 is sleeved on the outside of the limiting cylinder 41, and the first sliding sleeve 43 is slidably connected to the limiting cylinder 41 and fixedly connected to the fixing frame 6. The limiting cylinder 41 is fixed to the fixing seat 2 by the two first support columns 42. The limiting cylinder 41 guides the fixing frame 6 from the left side by cooperating with the first sliding sleeve 43.
[0030] Regarding the second guide component 5:
[0031] The second guide member 5 includes a limiting rod 51 and second support columns 52 located at the left and right ends of the limiting rod 51. The upper end of the second support column 52 is fixedly connected to the limiting rod 51, and the lower end of the second support column 52 is detachably connected to the fixed base 2. A second sliding sleeve 53 is sleeved on the outside of the limiting rod 51, and the second sliding sleeve 53 is slidably connected to the limiting rod 51 and fixedly connected to the fixed frame 6. The limiting rod 51 is fixed to the fixed base 2 through the two second support columns 52. The limiting rod 51 guides the fixed frame 6 from the right side by cooperating with the second sliding sleeve 53.
[0032] The adjusting device uses a screw drive to control the movement of the electric heating cable 7. Specifically, the adjusting device includes a screw 91, a slide groove 92, and a nut seat 93. The screw 91 is rotatably mounted inside the limiting cylinder 41. The slide groove 92 is opened at the lower end of the limiting cylinder 41. The nut seat 93 is sleeved on the outside of the screw 91 and threadedly connected to the screw 91.

A handle 9 for controlling the rotation of the screw 91 is provided on the outside of the limiting cylinder 41.
[0033] Rotating the handle 9 causes the screw 91 to rotate. As the screw 91 rotates, it engages with the nut seat 93. The nut seat 93 moves along the body of the screw 91. As the nut seat 93 slides along the slide groove 92, it moves along the first sliding sleeve 43. Adjusting the position of the fixing frame 6 allows the electric heating tape 7 to heat the photovoltaic panel 1 evenly. During the movement of the fixing frame 6, it also cleans the snow remaining on the photovoltaic panel 1, making maintenance convenient.
[0034] It is worth explaining in detail that the support frame 3 includes multiple triangular brackets 31. Each triangular bracket 31 has multiple mounting rods 32 on the side facing the photovoltaic panel 1. The mounting rods 32 are welded and fixedly connected to the triangular brackets 31. Several fixing bolts are mounted on the triangular brackets 31, and these fixing bolts are threaded into bolt holes on the back of the photovoltaic panel 1. After the triangular brackets 31 and mounting rods 32 are assembled in advance, the photovoltaic panel 1 is laid on one side of the triangular brackets 31. The triangular brackets 31 support the photovoltaic panel 1 through the mounting rods 32, and the photovoltaic panel 1 is fixed to the mounting rods 32 by the fixing bolts.
[0035] It is worth explaining in detail that the fixed base 2 includes several piers, and the upper end of the pier is provided with a bolt seat. The bolt seat is equipped with a mounting bolt, and the mounting bolt is threadedly connected to the bolt hole opened at the lower end of the triangular bracket 31.
[0036] To facilitate the assembly and disassembly of the fixed frame 6 and the two guide members, the first support column 42 and the second support column 52 are also fixed by a detachable connection method. Specifically, the lower end of the first support column 42 is equipped with multiple connecting bolts 8, which are threadedly connected to bolt holes opened on the outside of the pier column.
[0037] How this application works:
[0038] The electric heating cable 7 is a type of wire with a heating element. When snow accumulates on the photovoltaic panel 1, the electric heating cable 7 can provide stable heating power, effectively melting the snow and preventing damage to the photovoltaic panel caused by snow accumulation. To ensure uniform temperature distribution on the surface of the photovoltaic panel, the adjustment device on the first guide 4 can drive the electric heating cable 7 and the fixing frame 6 to slide on the surface of the photovoltaic panel 1, ensuring that no snow residue remains on the photovoltaic panel. The first guide 4 and the second guide 5 limit the electric heating cable 7 from the left and right ends. The first guide 4 and the second guide 5 are fixed to the fixing base 2 in a detachable installation method, facilitating the assembly and disassembly of the guides and the subsequent electric heating cable 7.
