论文摘要
Agrivoltaics（AV）是一种双重土地使用方法，可与农业共同生产太阳能，以保留陆地生态系统并实现食物能量 - 水协同作用。在这里，我们提出了一种系统的方法，可以对AV相对于独立的接地PV（GMPV）进行建模，并探讨模块设计配置如何影响双食品能量的经济性能。量化了一个非常简单的经济可行性标准，将土地保存成本与双重能源利润相关联。我们探讨了案例研究，包括沿常规北/南/南部（N/S）面或垂直东/西/西（E/W）面的固定倾斜双种族模块下的高价值作物和低价值作物。对于每种模块配置，对于一系列模块的土地成本比（M_L），阵列密度相对于GMPV的经济可行设计空间（M_L）探索阵列密度各不相同 - 与软（硬件和安装）成本相关的位置特定指标与软（土地获取，税收，税收，高架等）成本有关。为了抵消保留农田所需的通常较高的AV模块成本，E/W和N/S取向的模块都有利于高价值作物，减少（<60％）模块密度和更高的M_L（> 25）。相比之下，相对于GMPV，较高的模块密度和增加的馈电（拟合）在较低的M_L处是可取的。 M_L <10的经济趋势急剧变化，但对于M_L> 20倾向于饱和。对于低价值作物，〜15％的额外拟合度可以使经济在标准模块密度下与GMPV相同。提出的建模框架可以为AV利益相关者提供一个有价值的工具，以评估，预测和优化AV的技术经济设计
Agrivoltaics (AV) is a dual land-use approach to collocate solar energy generation with agriculture for preserving the terrestrial ecosystem and enabling food-energy-water synergies. Here, we present a systematic approach to model the economic performance of AV relative to standalone ground-mounted PV (GMPV) and explore how the module design configuration can affect the dual food-energy economic performance. A remarkably simple criterion for economic feasibility is quantified that relates the land preservation cost to dual food-energy profit. We explore case studies including both high and low value crops under fixed tilt bifacial modules oriented either along the conventional North/South (N/S) facings or vertical East/West (E/W) facings. For each module configuration, the array density is varied to explore an economically feasible design space relative to GMPV for a range of module to land cost ratio (M_L) - a location-specific indicator relating the module technology (hardware and installation) costs to the soft (land acquisition, tax, overheads, etc.) costs. To offset a typically higher AV module cost needed to preserve the cropland, both E/W and N/S orientated modules favor high value crops, reduced (<60%) module density, and higher M_L (>25). In contrast, higher module density and an increased feed-in-tariff (FIT) relative to GMPV are desirable at lower M_L. The economic trends vary sharply for M_L< 10 but tend to saturate for M_L> 20. For low value crops, ~15% additional FIT can enable economic equivalence to GMPV at standard module density. The proposed modeling framework can provide a valuable tool for AV stakeholders to assess, predict, and optimize the techno-economic design for AV
