[0002] With the progress of science and technology and the enhancement of environmental awareness, building photovoltaic integration (BIPV) technology is gradually becoming an important part of the construction industry. BIPV technology integrates photovoltaic power generation components with building materials, not only achieving energy self-sufficiency of buildings, but also improving the energy efficiency and environmental performance of buildings. However, in practical application, the construction of BIPV systems requires very high, especially in terms of drainage and lightning protection, the existing technology has some obvious shortcomings.

[0003] Currently, building photovoltaic integration systems are usually built on the rooftops of existing buildings or integrated as part of the building design. Since photovoltaic components need to be exposed to outdoor environments for a long time, their support structures and drainage systems must have good durability and stability. As an important component of the BIPV system, the keel structure of the power generation glass not only bears the weight of the photovoltaic components, but also needs to be closely combined with the drainage system to ensure that rainwater and cleaning water can be smoothly drained, avoiding water accumulation that can damage the system.

[0004] However, the existing drainage channel design often cannot meet the high requirements of BIPV systems. Traditional drainage channels usually use silicone or other sealing materials to seal the gaps. This sealing method is prone to loosening and damage under large diurnal temperature changes, leading to water leakage problems. In addition, the existing drainage channel structure is complex, with high installation and maintenance costs, and is not easy to closely match the keel structure of the power generation glass, affecting the overall performance and stability of the BIPV system. More importantly, the drainage channel design in the existing technology often ignores material conservation and cost control, making the construction and operation cost of the BIPV system high.

[0005] The existing photovoltaic components need to be welded with a circle of flat steel or round steel around the power generation glass to serve as a lightning protection and lightning arrestor. This structure affects the aesthetics.
