Ground-Mounted Solar Farms (Utility-Scale Solar Power Stations)
Description
Overview / 概述
Ground-mounted solar farms are large-scale PV installations built on open land, ranging from several megawatts to hundreds of megawatts. They feed electricity directly into the power grid and represent the most cost-competitive form of solar power generation on a per-kilowatt-hour basis.
地面集中式光伏电站是建在开阔土地上的大型光伏装置，容量从几兆瓦到几百兆瓦不等。它们直接向电网供电，是单位度电成本最具竞争力的太阳能发电形式。
Mounting Structure Details / 支架结构详情
Ground-mounted PV systems use steel pipe piles driven into the ground as the primary foundation. Hot-dip galvanized steel beams and purlins form the module mounting structure above. For utility-scale projects, single-axis or dual-axis
tracking systems are increasingly common, increasing energy yield by 20-30%.
地面光伏系统采用打入地下的钢管桩作为主要基础。热镀锌钢梁和檩条在上方形成组件安装结构。对于大型电站，单轴或双轴跟踪系统越来越普遍，可提高发电量20-30%。
