Building Integrated Photovoltaics (BIPV) refers to the integration of photovoltaic power generation systems with the exterior of buildings, making photovoltaic modules a part of the building. Its characteristics mainly include the following aspects:

1. 美觀性：BIPV光伏系統能夠與建筑外觀完美融合，不破壞建筑的整體美感，避免了傳統的光伏系統所帶來的視覺沖突和環境影響。

1. Aesthetics: BIPV photovoltaic systems can perfectly integrate with the exterior of buildings, without damaging the overall aesthetic of the building, avoiding the visual conflicts and environmental impacts brought about by traditional photovoltaic systems.

2. 綜合性能：BIPV光伏系統不僅能夠發電，還具備建筑外護、隔熱、防水等功能。通過光伏發電同時提供建筑保溫、節能等綜合效益，提高了建筑的整體能源利用效率。

2. Comprehensive performance: BIPV photovoltaic systems not only generate electricity, but also have functions such as building exterior protection, insulation, and waterproofing. By providing comprehensive benefits such as building insulation and energy conservation through photovoltaic power generation, the overall energy utilization efficiency of buildings has been improved.

3. 空間利用率高：BIPV光伏系統可以靈活應用于建筑的外墻、屋頂、陽臺、幕墻等位置，有效利用建筑表面空間進行光伏發電，大限度地提高了發電功率密度。

3. High space utilization: BIPV photovoltaic systems can be flexibly applied to exterior walls, roofs, balconies, curtain walls, and other locations of buildings, effectively utilizing the surface space of buildings for photovoltaic power generation, maximizing the power density of power generation.

4. 環境友好：BIPV光伏系統采用清潔能源進行發電，無燃料消耗、無污染物排放，對環境影響較小，符合可持續發展的理念。

4. Environmentally friendly: BIPV photovoltaic systems use clean energy for power generation, without fuel consumption and pollutant emissions, with minimal environmental impact and in line with the concept of sustainable development.

5. 維護成本低：BIPV光伏系統集成于建筑中，相比傳統鎖定式光伏系統更容易進行日常維護和保養，降低了維護成本。

5. Low maintenance cost: BIPV photovoltaic systems are integrated into buildings, making it easier to perform daily maintenance and upkeep compared to traditional locked in photovoltaic systems, reducing maintenance costs.

6. 可持續性發展：BIPV光伏系統能夠利用建筑表面空間進行發電，為建筑提供自給自足的能源支持，促進了可持續發展的實現。

6. Sustainable development: BIPV photovoltaic systems can utilize building surface space for power generation, providing self-sufficient energy support for buildings, and promoting the realization of sustainable development.

總之，BIPV光伏建筑一體化具有美觀、綜合性能好、高空間利用率、環境友好、維護成本低以及可持續性發展等特點。

In summary, BIPV photovoltaic building integration has the characteristics of aesthetics, good comprehensive performance, high space utilization, environmental friendliness, low maintenance costs, and sustainable development.
