Agrivoltaics (AV) offers a promising solution to address both food and energy crises. However, crop growth under photovoltaic (PV) conditions faces substantial challenges due to insufficient light transmission. We propose a large-scale and cost-effective spectral separated concentrated agricultural photovoltaic (SCAPV) system. The system utilizes concentrator modules, cell components, and dual-axis tracking systems to enhance power conversion efficiency (PCE), achieving a maximum PCE of 11.6%. After three years of successful operation, a 10 kWp power plant achieved an average annual electricity generation exceeding 107 MWh/ha. The results showed higher yields of various crops, including ginger and sweet potatoes, and significant improvements in soil moisture retention compared to open air. The improvements in PCE and microclimate validate the scalability of the SCAPV, which provides better plant conditions and cost-effectiveness, with an estimated cost reduction of 18.8% compared to conventional PV power plant. This study provides valuable insights and directions for improvement in AV.

通过光谱分离实现大规模且经济高效的农业光伏系统
农业光伏(AV)为解决粮食和能源危机提供了一种有前景的解决方案。然而,由于光传输不足,光伏(PV)条件下的作物生长面临着巨大的挑战。我们提出了一种大规模且经济高效的光谱分离聚光农业光伏(SCAPV)系统。该系统利用聚光模块、电池组件和双轴跟踪系统来提高功率转换效率(PCE),最高PCE达到11.6%。经过三年的成功运营,一座10kWp发电厂的平均年发电量超过107MWh/ha。结果显示,与露天相比,包括生姜和甘薯在内的各种作物的产量更高,土壤保水性也显着改善。 PCE和微气候的改进验证了SCAPV的可扩展性,它提供了更好的电站条件和成本效益,与传统光伏电站相比,预计成本降低18.8%。这项研究为 AV 的改进提供了宝贵的见解和方向。
