摘要
随着光伏应用领域的拓展,农光互补、渔光互补等生态发电模式成为新宠,水上光伏也由于其不占用陆地面积而成为当前的热点之一.传统光伏系统中,组件通常采用最优倾角放置.但是,在水上光伏系统中可能会由于系统规模较大,形成风帆效应,降低系统的稳定性和安全性.为此,本工作设计了三种放置方式,并对其进行了晴朗天气下的对比测试.结果显示:晴朗天气时,大倾角放置的光伏组件由于接收到最高的辐照度,可产生最高的输出功率;太阳辐射较弱的上午和傍晚,由于水面漫反射,水平放置(或小角度放置)组件表现好的弱光效应;水平且无漂浮板的放置方式,最有利于光伏组件的散热.
With the expansion of application of photovoltaic,Complementary light and Complementary fishing light are turning into favorite and water photovoltaic is becoming preferring,due to not occupy the land area.In traditional photovoltaic system,modules are usually put with optimal angle.While,for water photovoltaic system,because of large scale,wide angle might lead to sail effect,and bring into low stability and safety.So in this paper,three putting conditions were selected,and parameters of module samples were tested and compared on sunny day.The results showed that the module with optimal angle could be give the highest out-power,due to the best accepted radiation;while the module with would display good weak light effect,due to diffuse reflection of water;the module with small angle and without floating plate could be cooled very well,due to heat dissipation of water.
