摘要
提出一种低成本利用光伏组件阵列行间光照的反光增效设计。就南昌地区七月初晴天正午条件分别进行单组件反光增效计算模拟和实验。结果显示,行间反光板倾斜角为43°±1.5°时的反光增效效果最好,与计算模拟结果吻合良好。进一步在该最佳反光板倾斜角条件下进行全天实验,结果显示其反光增效效果并不会随太阳高度角减小而明显下降。原因在于太阳辐照中漫散射光和反射板表面漫反射部分的贡献,它们对太阳高度并不敏感。采用白色铝塑板材质的反光板,本设计可使光伏组件表观标称功率提升6%。
A low cost design of power gaining through utilization of the inter-row light by reflection in PV array was proposed.Computation and experiment of a single module set up were carried out during noon time on a sunny date in July,in Nanchang area.The results indicate that the optimum tilt angle of the inter-row reflecting board is 43°±1.5°.Further whole day experiment was conducted with the optimum tilt angle.The results show that the power gaining does not significantly decrease with lowering of the solar height.This is due to the contributions from the diffused light in solar radiation,and from the diffused reflection on the reflecting board.Using a white aluminum-plastic sheet as the reflecting board,the present design can achieve 6%power gain.
