Abstract

The present study examined the performance of the 100 kWp agri-voltaic systems at ICAR-CAZRI, Jodhpur. The average PV generation from the 100 kWp AVS connected to the grid via a bi-directional energy meter or net meter was about 342 kWh day-1. The average yields of mung bean, moth bean, and cluster bean in the inter-row spaces between the modules in the two-row and three-row PV array were 1155, 670, and 2008 kg.ha-1, respectively. Thus, there were 4.6%, 8.6%, and 11.8% reductions in the yield of mung bean, moth bean, and cluster bean, respectively, in inter-row spaces between the panels compared to control. During Rabi (irrigated) 2021-22, the yield of chickpea, cumin, and isabgol (2490, 1000, and 700 kg ha-1, respectively) in interspaces of the AVS was lower than that of the control (2670, 1120, and 760 kg ha-1, respectively). AVS resulted in a yield reduction of 6.6, 10.3, and 7.8% in chickpea, cumin, and isabgol, respectively, compared to the control. The AVS shows the maximum IRR (20.38%), while PV-GM shows the lowest (19.42%) at the prevailing bank loan interest rate of 12%. The PBP estimated 7.47 years for AVS with irrigated crops and 8.11 years for AVS with rainfed crops, while it was 8.61 years for PV-GM. The lower value of the discounted PBP, the faster the repayment of the investment cost. Therefore, the highest LCOE (INR 3.45 kWh-1) is estimated based on the break-even electricity tariff in PV-GM, and the lowest LCOE is calculated in AVS (INR 3.17 kWh-1).

印度塔尔沙漠农业光伏系统评估

本研究考察了焦特布尔 ICAR-CAZRI 的 100 kWp 农业光伏系统的性能。通过双向电能表或网表连接到电网的 100 kWp AVS 的平均光伏发电量约为 342 kWh/天-1。在两行和三行光伏阵列中，模块之间的行间空隙中绿豆、蛾豆和四季豆的平均产量分别为 1155、670 和 2008 千克/公顷。因此，与对照组相比，板间行间距内的绿豆、蛾豆和四季豆产量分别减少了 4.6%、8.6% 和 11.8%。在 2021-22 年的拉比（灌溉）期间，反车辆影响系统间距内鹰嘴豆、小茴香和异蚕豆的产量（分别为每公顷 2490、1000 和 700 千克）低于对照（分别为每公顷 2670、1120 和 760 千克）。与对照相比，反车辆地雷导致鹰嘴豆、小茴香和异麦芽分别减产 6.6%、10.3%和 7.8%。在现行银行贷款利率为 12% 的情况下，AVS 的内部收益率最高（20.38%），而 PV-GM 的内部收益率最低（19.42%）。采用灌溉作物的 AVS 的 PBP 估计为 7.47 年，采用雨水灌溉作物的 AVS 为 8.11 年，而 PV-GM 为 8.61 年。贴现 PBP 值越低，投资成本的偿还速度越快。因此，根据 PV-GM 的盈亏平衡电价估算出的 LCOE 最高（3.45 印度卢比-1 千瓦时），而 AVS 计算出的 LCOE 最低（3.17 印度卢比-1 千瓦时）。
