The rising trend of solar PV generation from ground based installations has led to competition for land
between agriculture and PV generation. The solution to this challenge lies in the agri-voltaic system
(AVS). The AVS systems allows agricultural activities on land while provides opportunity for PV generation
and thus returns additional income from land. Therefore, the Governments of many countries e.g.
Japan, France, USA, South Korea, and China have already introduced policies for installation of AVS on
agricultural land. Following this trend, policy to install AVS in farmers field has also been launched in
India under the national level scheme called KUSUM (Kisan Urja Suraksha evam Utthan Mahaabhiyan)
targeting for energy security and upliftment campaign for farmers. Under the scheme, subsidy is gurranted
for installation of PV power plants in farmers field with a capacity between 0.5 and 2 MWp and
on-grid net metering connection of the PV power plant. After announcement of the scheme, there has
been increasing interests for installation of AVS by farmers, however, limited knowledge on technoeconomic
performance of the system, field scale installations of it has been hindered. In the present
study, techno-economic analysis of different designs of AVS systems (105 kWp) established at ICARCentral
Arid Zone Research Institute has been evaluated with several combinations of rainfed and irrigated
crops. Field performance of the AVS system of 105 kWp has been used to extrapolate cost and
returns for 520 kWp system, which lies in the range of KUSUM target. Five AVS designs were considered
in the study: extrapolated into 520 kWp AVS and compared theoretically with the price and returns of a
photo-voltaic ground-mounted (PV-GM) plant the same capacity. Among five designs of PV arrays in the
AVS, the one-row full density photovoltaic array with irrigated brinjal recorded the highest combined net
returns of PV รพ crop components followed by rainfed snap melon. Based on the highest returns per
hectare basis, the economic analysis of AVS design for rainfed and irrigated crops is compared to PV-GM.
The higher values of life cycle benefit (LCB) could lead to higher net present worth (NPW) of AVS over PVGM.
The higher values of internal rate of return (IRR) in AVS lead to quicker repayment of investment cost
as indicated by the pay-back period (PBP), which is shorter by 0.5 and 1.14 years in AVS one row PV array
in rainfed and irrigated as compared to PV-GM (8.61 years). Moreover, the one row PV array with irrigated
had the lowest Levelized cost of electricity generation (LCOE) (INR 3.17 kWh 1), which is much
lower than the prevailing electricity tariff (INR 5.0 kWh 1). Hence, it is inferred that crop production can
be very economical for an AVS. AVS technology shows flexibility up to 6% escalation in cost with no
escalation in returns, as is indicated by sensitivity analysis. One row full density with irrigated is found
the best system based on sensitivity analysis and economic feasibility. The economic analysis of AVS
designs in this study is similar to the cost of other PV systems worldwide. Therefore, all PV systems
analyzed represent a relatively safe investment.
