Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic structure technical field especially relates to a photovoltaic skylight integrated structure. BACKGROUND

[0002] With the increasing demand for renewable energy worldwide, solar photovoltaic technology is increasingly widely used in the field of building. As a technology that combines photovoltaic hollow integrated components with building structures, building integrated photovoltaic (BIPV) not only achieves the aesthetic appearance of buildings, but also effectively utilizes solar energy resources and reduces building energy consumption. Photovoltaic skylight, as an important application form of BIPV technology, combines photovoltaic modules with building skylights, meeting the building lighting needs and achieving solar power generation functions.

[0003] However, in the practical application of photovoltaic skylight curtain wall system, the connection line (cable) arrangement problem of photovoltaic modules has not been effectively solved, resulting in the following technical problems and limitations:

[0004] 1. Photovoltaic hollow integration, ordinary photovoltaic modules are single-layer.

[0005] 2. The exposed connection line affects the appearance. In the traditional photovoltaic skylight system, the connection line of the photovoltaic module is usually exposed, especially at the junction of the skylight and the window frame. The chaotic arrangement of the cable seriously affects the overall aesthetic appearance of the building. The exposure of the connection line makes the building facade look untidy, reducing the high-end and modern feel of the building.

[0006] 3. Safety hazards. Exposed connection lines are easily affected by external environments (such as rain, ultraviolet light, mechanical wear and tear, etc.), which may cause cable aging, insulation layer damage, and thus cause short circuit, leakage and other safety hazards.

[0007] 4. Complex installation and maintenance. In the traditional photovoltaic skylight system, the arrangement of the connection line requires additional wire slots or protective sleeves, increasing the construction difficulty and cost. Due to the exposure of the connection line, frequent disassembly and reinstallation are required during maintenance and repair, increasing maintenance costs and workload.

[0008] 5. Limited design flexibility. The exposure of the connection line limits the design flexibility of the photovoltaic skylight system. Architects need to consider additional cable arrangement and hiding issues when designing, affecting the design freedom and innovation. In traditional design, the arrangement of the connection line is usually separated from the building structure, making it difficult to achieve seamless integration of photovoltaic modules and building skylights.

[0009] 6. Durability issues

[0010] Exposed wiring is susceptible to environmental corrosion (such as rain, dust, and temperature changes), which may lead to a decline in cable performance and affect the long-term stable operation of the photovoltaic system. The durability issues of the wiring increase the frequency and cost of system maintenance, reducing the economic viability of the photovoltaic skylight curtain wall system.

[0011] 7. Waterproofing issues: Most skylights currently have waterproofing problems. The sealant joints cannot effectively solve the waterproofing problem, and long-term aging will cause the skylight to leak. Utility Model Content
