Solar PV Application Scenarios
Rooftop Photovoltaic Systems (Industrial & Commercial Rooftop PV)
Description
Overview / 概述
Rooftop photovoltaic systems are installed on the roofs of residential, commercial, and industrial buildings. Industrial and commercial rooftop PV is the most economically attractive segment due to large roof area, high daytime consumption, and favorable electricity prices.
屋顶光伏系统安装在住宅、商业和工业建筑的屋顶上。其中工商业屋顶光伏因屋顶面积大、白天用电量大、电价优势明显 ，是经济效益最好的细分领域。
Mounting Structure Details / 支架结构详情
Industrial rooftop PV systems typically use an aluminum alloy rail mounting system. Roof hooks or clamps are securely fastened to the roof structure, and horizontal aluminum rails are then mounted to these hooks. PV modules are
secured to the rails using mid-clamps and end-clamps. Waterproof flashing is critical at all roof penetration points.
工业屋顶光伏系统通常采用铝合金导轨式支架系统。屋顶挂钩或夹具牢固固定在屋面结构上 ，然后将水平铝合金导轨安装在挂钩上。光伏组件通过中压块和边压块固定在导轨上。所有屋面穿透点的防水处理至关重要。
