工商业光伏支架系统
BIPV 光伏系统
BIPV（Building Integrated Photovoltaic）工商业光伏系统是光伏建筑一体化的专业解决方案，将太阳能发电方阵直接作为建筑围护结构（屋面）的一部分。与传统的“支架+组件”在屋顶上加装的模式不同，BIPV系统直接替代常规彩钢瓦屋面，光伏组件既是发电单元，也是屋面的防水层和结构层，实现发电与建筑功能的一体化
核心参数：
参数 | 数值 |

核心优势：
全防水性能：采用专利结构性防水+密封条设计，形成三层或多重密封，杜绝渗漏隐患，不打胶、不贴胶，排水设计科学；
替代传统屋面：直接作为建筑屋面材料，节省传统彩钢瓦的采购和安装成本，经济性突出；
超长使用寿命：设计寿命25年以上，远超普通彩钢瓦（约10~15年），一次投资，长期收益；
轻量化设计：全铝或镀镁铝锌材质，重量约为常规全钢产品的三分之一，对屋面荷载小，适用范围更广；
设计创新：导轨顶面高于组件的设计，防积水防异物；充分考虑不同材料的电位差，避免电位腐蚀；
功能完备：满足建筑抗风压、气密性、水密性三大性能要求，兼具隔热防火、防震防水、运维便捷等优点。
适用场景：
新建钢结构厂房：BIPV系统直接作为屋面，替代传统彩钢瓦+后期加装光伏的方案；
旧厂房改造：直接拆除老旧彩钢瓦屋面，更换为BIPV系统，实现屋面翻新与光伏发电一举两得；
大型商业建筑、物流仓库、公共建筑屋顶；
关于荷载的补充说明：根据工程设计规范，混凝土屋面采用BIPV阵列式支架时，风压0.8~1.0kN/㎡地区新增光伏荷载约为1.5~2.0kN/㎡；风压0.5~0.8kN/㎡地区约为1.2~1.5kN/㎡。轻量化BIPV系统重量仅为常规全钢产品的三分之一，对屋面承重要求更低。
BIPV System
BIPV(Building Integrated Photovoltaic) commercial and industrial PV system is a professional building-integrated PV solution that makes the solar array part of the building envelope (roof) itself. Unlike the traditional "mounting + module" rooftop retrofit approach, a BIPV system directly replaces the conventional colored-steel roof: the PV modules serve both as power-generation units and as the roof's waterproofing and structural layers, integrating power generation with building functions
Core Parameters:
Parameter | Value |
Material | Aluminium alloy 6063-T5/Hot-dip galvanised steel |
Wind load resistance | 50 m/s |
Snow load | 1.5 kN/m² |
Design life | 25 years |
Warranty | 10 years |
Core Advantages:
Full waterproof performance: Patented structural waterproofing plus sealing-strip design forms three or more sealing layers, eliminating leakage risks; no glue or adhesive tape is used, and the drainage design is scientific;
Replaces conventional roofing: acts directly as building roof material,saving the procurement and installation costs of conventional colored-steel tiles, delivering outstanding cost-effectiveness;
Extra-long service life: design life of over 25 years, far exceeding ordinary colored-steel tiles (about 10–15 years); one-time investment with long-term returns;
Lightweight design: made of all-aluminium or Zn-Al-Mg material, weighing about one third of conventional all-steel products,exerting little load on the roof, with wider applicability;
Innovative design: the rail top surface is higher than the modules to prevent water and debris accumulation; potential differences between materials are fully considered to avoid galvanic corrosion;
Complete functionality: meets the three major building performance requirements of wind-pressure resistance, air tightness and water tightness, and also offers thermal insulation, fire protection, earthquake and water resistance, and convenient O&M.
Application Scenarios:
New steel-structure factory buildings: the BIPV system serves directly as the roof, replacing the traditional "colored-steel tile + later PV retrofit" approach;
Old factory renovation: the old colored-steel roof is removed and replaced with a BIPV system, achieving both roof renovation and PV power generation in one step;
Large commercial buildings, logistics warehouses, public buildings roofs;
Building façades: curtain-wall systems, exterior decorative façade systems, etc..
Supplementary notes on loads: according to engineering design codes, when a concrete roof adopts a BIPV array-type mounting system, the added PV load is about 1.5–2.0 kN/m² in areas with a wind pressure of 0.8–1.0 kN/m² and about 1.2–1.5 kN/m² in areas with a wind pressure of 0.5–0.8 kN/m². The lightweight BIPV system weighs only one third of conventional all-steel products, imposing lower load-bearing requirements on the roof.
