No Chinese content provided, so the translation remains the same: "Light."BIPV, or Building Integrated Photovoltaics, is a technology that integrates solar power generation products into buildings. Unlike photovoltaic systems that are simply attached to buildings, BIPV can generally be categorized into two types: one involves the combination of photovoltaic arrays with buildings, and the other involves their integration, such as photovoltaic roof tiles, photovoltaic facades, and photovoltaic skylights. In these two approaches, the combination of photovoltaic arrays with buildings is a common method, particularly with building roofs. However, there are still some shortcomings in the manufacturing technology of BIPV component supports. For instance, the waterproofing effect of existing BIPV component supports is generally poor, leading to excessive water accumulation on the photovoltaic components during rainy or snowy weather. This not only affects the normal absorption of solar energy but also impacts the lifespan of the photovoltaic components. Particularly in regions with frequent rainy and cloudy days like Jiangnan, a large number of photovoltaic components often need to be replaced due to inadequate waterproofing, significantly increasing the cost of power generation.
