Description

Technical Field

[0001] The invention relates to a building profile that integrates photovoltaic and energy storage components. Background Art

[0002] With global climate change and environmental pollution becoming increasingly severe, sustainable development has become a global issue. The vision of utilizing renewable energy and reducing energy consumption and emissions demands concerted efforts. According to surveys, in some developed countries, buildings already account for 30% to 40% of national energy consumption annually. Consequently, reducing building energy consumption has become a major research topic for environmental protection departments worldwide, leading to the emergence of the concept of green building. Solar energy, as a green and renewable energy source, has rapidly developed in the field of green building. Currently, solar power generation technology is widely used, including photovoltaic systems installed on building surfaces to convert sunlight into electricity. Traditional building-integrated photovoltaic (BIPV) systems, or distributed generation systems applied to building rooftops, consist of conventional photovoltaic modules fixed to the rooftop with simple drainage systems. This installation not only detracts from the aesthetics of the existing roof but also increases the load on the building. The current photovoltaic integrated structure usually has the following thermal insulation and heat dissipation structures. First, by forming an air inlet and an air outlet between the solar cell laminated assembly and the upper and lower ends of the aluminum profile, an air flow channel is formed between the air inlet and the air outlet, and the heat of the air flow channel is carried away by the air flow. This structure will destroy the overall integrity and cause the anti-penetration and waterproof functions to decline. Second, an automatic spray device is set up. Under this structure, the structure is complex and will increase the weight burden of the aluminum profile. Summary of the Invention
