Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, and specifically to a full-screen BIPV photovoltaic module. Background Art

[0002] In recent years, the rapid development of the national economy has not only driven the overall construction industry toward green, environmentally friendly, clean energy, and environmentally friendly approaches, but has also stimulated the development of new energy and renewable energy sectors. Consequently, the photovoltaic industry has shown positive growth within the construction sector, with the development of photovoltaic-building integrated systems (BIPV) being particularly prominent. The vigorous development of integrated photovoltaic buildings is a key step in my country's building energy transition, and its strategic significance for sustainable development is highly recognized.

[0003] BIPV, or building-integrated photovoltaics, is a technology that installs solar photovoltaic arrays on the exterior of buildings to absorb solar energy and provide electricity. Compared to conventional photovoltaic modules, BIPV does not require additional photovoltaic brackets, resulting in lower installation costs and the ability to blend in with architectural designs for a more aesthetically pleasing appearance. BIPV has a wide range of applications, including residential, commercial, and industrial buildings. With the pursuit of green buildings and sustainable development, more and more building owners are beginning to recognize the advantages of BIPV technology and are actively adopting it, which means the BIPV market has enormous potential and broad development prospects.

[0004] Traditional BIPV modules still share the same pain points as other conventional modules, especially when installed at shallow angles on commercial and industrial rooftops. This is because traditional BIPV module frames use the same design with an A-side as conventional modules. The A-side is 2-3 mm higher than the front of the laminate. Dust accumulates around the modules when used outdoors. Even when it rains or when the module surface is cleaned and maintained, the wastewater flows toward the lower end of the module, and some water cannot flow over the frame. Once the accumulated water dries in the sun or air, dust forms on the glass surface, eventually forming a mud band. Mud bands are more pronounced for arrays with low inclination angles or rooftop power stations. Once a mud band forms, the obscured cells cannot generate electricity and form hot spots, which in turn reduces the power generation of the photovoltaic power station, accelerates module aging, and even causes fire accidents. Utility Model Content

[0005] In order to solve at least one technical problem of the prior art, the present invention provides a full-screen BIPV photovoltaic module that will not produce mud belts when used outdoors and will not jam or explode when assembling the full-screen BIPV photovoltaic module.

[0007] The adhesive portion includes a first adhesive plate connected to the supporting portion and a second adhesive plate extending upward from the first adhesive plate away from the long side of the laminate, the first adhesive plate and the second adhesive plate forming a support platform for supporting and limiting the edge of the laminate, the lower surface of the edge of the laminate is respectively bonded to the upper surface of the first adhesive plate, and the side surfaces of the edge of the laminate are respectively bonded to the inner surface of the second adhesive plate, and the height of the second adhesive plate does not exceed the upper surface of the laminate;

[0008] A concave glue storage portion is provided at the junction of the first adhesive plate and the second adhesive plate.

[0009] In certain embodiments, a depth component of the glue storage portion increases in a direction from a position away from the second adhesive sheet toward a position of the second adhesive sheet.

[0010] In some embodiments, the upper surface of the first adhesive sheet includes a main surface and an inclined surface constituting the bottom surface of the adhesive storage portion, wherein the inclined surface extends from the main surface toward the second adhesive sheet at an angle relative to the plane of the main surface.

[0011] In certain embodiments, the angle between the second adhesive sheet and the inclined surface is less than 90°.

[0012] In certain embodiments, the top of the second adhesive sheet has a raised portion protruding toward the laminate, and the raised portion extends along the length direction of the second adhesive sheet.

[0013] In certain embodiments, the maximum thickness L1 of the first adhesive sheet is 1.2-1.6 mm, and the height H1 of the second adhesive sheet is 4.8-5.5 mm.

[0014] In some embodiments, the support portion includes a first support plate and a second support plate arranged in parallel and spaced apart, the upper ends of the first support plate and the second support plate are fixedly connected to the lower surface of the first adhesive plate, and the lower ends of the first support plate and the second support plate are fixedly connected to the mounting portion.

[0015] In some embodiments, the first support plate, the second support plate, the first adhesive plate, and the mounting portion are arranged to form a cavity, and two adjacent frames are connected together by corner brackets installed in the cavity.

[0017] In some embodiments, the thickness L2 of the bottom plate is 1.5-2.0 mm, and the height H2 of the hook is 2-3 mm.

[0018] The beneficial effects of the present invention are: since the frame has no A edge and the second adhesive plate of the frame does not exceed the upper surface of the laminate, the component is not prone to large amounts of dust accumulation, eliminating the generation of mud strips when the full-screen BIPV photovoltaic component is used outdoors, thereby eliminating the hot spot effect caused by the mud strips. At the same time, the frame will not block the laminate, increasing the light-receiving area of ​​the laminate, improving the power of the full-screen BIPV photovoltaic component, and eliminating the risk of the laminate being stuck and exploded when the frame is framed; and the overall height of the component is reduced, and the same-sized packaging box can hold more components, reducing the transportation cost of the component.
