海上光伏支架系统
海上光伏支架系统是专为海洋环境开发的光伏支撑解决方案，分为桩基固定式和漂浮式两大类型。桩基固定式适用于水深较浅的近海区域，采用钢管桩基础+钢桁架平台结构；漂浮式适用于水深较大的海域，采用浮体+索网系统或环形浮体结构。该系统需同时满足发电支撑和抵御海洋极端环境（台风、波浪、盐雾、潮汐）的双重要求。

轻量化与低成本：漂浮式方案单套支架自重较传统钢结构降低40%，运输成本减少30%，安装效率提升50%；索网柔性结构只承受拉力，可充分发挥材料抗拉强度，减少材料用量；
大跨度适应性：漂浮式单支架最大直径≥100米，单套容量可根据项目需求调整；柔性支架方案可适应50米以上跨度需求，适合“渔光互补”等场景。
适用场景：
近海浅水区（水深<10m）：桩基固定式支架；
滩涂、海岛：可根据地质条件选择固定式或漂浮式；
渔光互补、海上风光同场等复合利用场景
Offshore PV Mounting System
The offshore PV mounting system is a PV support solution developed specifically for the marine environment, divided into pile-fixed and floating two main types. The pile-fixed type is suitable for shallow offshore areas and uses a steel pipe pile foundation + steel truss platform structure; the floating type is suitable for deeper waters and uses a float + cable-net system or annular float structure. The system must simultaneously provide power-generation support and withstand extreme marine conditions (typhoons, waves, salt spray and tides).
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 |
Adaptability to extreme environments: wind resistance up to 50–60 m/s (able to withstand category 12–17 typhoons) and wave resistance up to 4 m wave height; basalt-fibre composite profiles absorb more than 30% of the dynamic wind-wave load energy through elastic deformation, improving stability in extreme environments by 40%;
Full-lifecycle anti-corrosion: a combined "coating protection + cathodic protection" anti-corrosion system with a design anti-corrosion life of 25 years; choosing corrosion-resistant materials such as 316 stainless steel can further enhance corrosion resistance;
Lightweight and low cost: the floating solution reduces the self-weight of each mounting set by 40% compared with traditional steel structures, cuts transport costs by 30% and improves installation efficiency by 50%; the cable-net flexible structure bears only tension, fully exploiting the tensile strength of materials and reducing material consumption;
Large-span adaptability: the maximum diameter of a single floating bracket is ≥100 m, and the capacity per set can be adjusted to project requirements; the flexible mounting solution can accommodate spans of over 50 m, suiting scenarios such as "fishery-PV complementarity".
Application Scenarios:
Nearshore shallow water(water depth <10 m): pile-fixed mounting systems;
Nearshore deep water / open sea: floating mounting systems (float type or cable-net flexible type);
Tidal flats and islands: fixed or floating types can be selected according to geological conditions;
Fishery-PV complementarity and co-located offshore wind-PV and other combined-utilisation scenarios
