为有效分析双面光伏组件、平单轴跟踪技术较固定倾角单面光伏组件的辐照度的增益,通过固定倾角和平单轴视日运行轨迹分析,利用视觉因子方法,构建平单轴双面光伏组件辐照度模型。通过测试与分析,当组件阵列宽度为2 m、行间距为5 m、组件离地高度为2 m、地面反射率为0.2、双面系数为0.75的情况下,杭州地区的双面、平单轴、平单轴双面的辐照度增益分别为0.076、0.078、0.161;此外,当水平散射辐射量占比越高,双面增益越明显,水平直射辐射量占比越高,平单轴增益越明显。为不同地区的平单轴、双面光伏组件的安装与应用,提供理论指导。
Abstract
For effectively analyzing the irradiance gain of bifacial PV modules and single-axis PV modules with ray tracing technique in contrasting to single-axis PV modules with a fixed tilt, an irradiance model of single-axis bifacial PV modules was established on the basis of the visual factor method and the daily trajectory characteristics of fixed tilt and single-axis. The testing and analysis demonstrated that the irradiance gain of bifacial, single-axis, and single-axis bifacial in the Hangzhou district were 0.076, 0.078, and 0.161, respectively, in the condition of array width of 2 m, row distance of 5 m, assembly height of 2 m, ground reflectance of 0.2, and double-sided coefficient of 0.75. In addition, the bifacial gain will be greater in the case of a higher horizontal component of scattered radiation. whereas, the single-axis gain can be increased greatly only in the condition of a higher horizontal component of direct radiation. These results can be theoretical guidance for the installation and application of single-axis and bifacial PV modules in different areas.
