wind and snow loads for module组件风雪荷载设计值与安全系数的乘积，评估组件在户外载荷下结构机械性能和稳定性的荷载。注： 对应 GB/T 9535.1—2025 中组件荷载测试值。4 基本规定4.1 光伏电站的光伏组件应按 25 年重现期确定基本风压和基本雪压。用于气象数据统计的风压和雪压资料应符合 GB 50009—2012 的相关规定，或按有关规范的规定采用。4.2 光伏组件表面的风压不均匀分布，采用二分区风荷载体型系数分布模型，作用在光伏组件的风荷载体现为垂直于光伏组件板面的压力及绕光伏组件中心短轴的弯矩。4.3 阵风系数是瞬时风荷载与平均风荷载的比值，仅仅考虑瞬时变化的脉动风荷载，适用于支架刚性1GB/T 48103—2026较强的结构。固定支架光伏组件表面风荷载标准值计算宜采用阵风系数。4.4 风振系数既包括瞬时变化的脉动风荷载，又包含结构的动态响应。对风敏感的跟踪支架和柔性支架结构需要考虑结构的动态响应，宜采用风振系数计算风荷载标准值。4.5 光伏组件设计宜考虑使用过程中在结构上可能同时出现的风荷载和雪荷载，宜取其最不利的组合荷载进行设计。5 风雪荷载计算5.1 风荷载5.1.1 对固定支架结构，垂直作用于光伏组件表面上的风荷载标准值，按公式（1）计算：ω k = βgz μz μsω 0…………………………（ 1 ）式中：ω k ——风荷载标准值，单位为千牛每平方米（kN/m2）；βgz ——高度 z 处的阵风系数，固定支架刚度较强，不考虑结构的动态响应，可按 5.1.3 取值；μz ——风压高度变化系数，可按 5.1.4 取值，地面光伏电站组件可取光伏板顶端高度；μs ——风荷载体型系数，可按 5.1.6 取值；ω 0 ——基本风压，单位为千牛每平方米（kN/m2），可按 GB 50009—2012 取值。5.1.2 对跟踪支架与柔性支架结构，垂直作用于光伏组件表面上的风荷载标准值，按公式（2）计算：ω k = βz μz μsω 0…………………………（ 2 ）式中：ω k ——风荷载标准值，单位为千牛每平方米（kN/m2）；βz ——高度 z 处的风振系数；由于跟踪支架和柔性支架风场的干扰特性及风振响应的特殊性，跟踪支架和柔性支架光伏组件风...
