法国农业光伏专家Sun’Agri分享了两个位于法国南部东比利牛斯省Domaine de Nidolères的农业光伏试点基地的2024年收成结果。他们分别测试了三个葡萄品种。
结果表明，与未安装光伏组件的区域相比，太阳能电池板下的葡萄产量提高了20%至60%。其中，霞多丽葡萄的产量增幅最大，达60%；其次是马瑟兰（30%）和白歌海娜（20%）。
而在法国东南部沃克吕兹省的第二个试点基地，葡萄产量增幅都保持在30%以上，不论是否灌溉。
Sun’Agri将产量增长归因于农业光伏系统优化微气候的能力，太阳能电池板可以调节温度、增加湿度并减少20%至70%的灌溉需求。
该公司表示，农业光伏系统还可以预防霜冻，阻止温度下降多达2℃。因此，这提高了植物的存活率，使死亡率降低了25%至50%。
此外，采用在电池板下种植的葡萄酿制的葡萄酒酒精度降低了1.5%，在保持白葡萄酒酸度的同时增强了香气特征。
