摘要

摘要: 农光互补作为将光伏发电与农业生产有机结合的新能源应用形式，具有重要的生态效益和经济收益潜力，但因难以解决光伏组件和农作物采光分配的问题而推广不力。设计一种新型农光互补方阵，在光伏组件表面镀制由11层SiO₂膜和11层TiO₂膜组成的滤光多层膜，将农作物光合作用所需的红光和蓝光分离出来，通过方阵倾角的实时调整构成的反射光路照射到地面上，而其他波段的光则透过滤光膜，照射太阳能电池，进行光伏发电。设计该方阵的组件排布形式和阵列间距，使用PVsyst软件建模，计算方阵的发电量和阵列间地面光照，计算结果表明其发电量虽然低于常规固定倾角方阵，但阵列间地面光照增加27.26%，有助于提高农作物的产量，从而提高农光互补项目的综合效益。

Abstract: As a new energy application form that organically combines photovoltaic（PV） power generation and agricultural production,agro-photovoltaic integrating system has important ecological benefits and economic potential. However, suffering for the problem of photovoltaic modules and crop lighting distribution, it is difficult to apply it widely. In this regard, a new type of agro-photovoltaic system was designed. A multilayer film filter comprising of 11 layers of SiO₂ film and 11 layers of TiO₂ film was coated on the surface of photovoltaic modules to separate the red and blue light required for crop photosynthesis from solar spectrum. Through real-time adjustment of the inclination of the PV array, the reflected light kept illuminating the ground, while other wavelengths of light passed through the filter film and illuminated the solar cell, leading to generation of photovoltaic power. The PV modules arrangement and spacing of the PV array was designed, and the power generation of the PV array and the ground illumination between the arrays were calculated with PVsyst software modelling. The calculation results showed that although its power generation was lower than the conventional fixed inclination square array, the ground illumination between the arrays had increased by 27.26%, which helped to increase the yield of crops, thereby increasing the comprehensive benefits of the agro-photovoltaic projects.
