Model Answer
1. Efficient Use of Agricultural Land:
Agrivoltaics allows farmers to use the same land for both crop production and solar energy generation, optimizing space and resource utilization. For instance, in the Vidarbha region, a six-acre agrivoltaic system combined with a 100MW solar installation allowed farmers to continue regular agricultural activities while producing renewable energy.
2. Enhanced Agricultural Productivity:
The shade provided by solar panels helps create a microclimate that reduces plant stress, especially in areas with intense sunlight. A study in Greece found that solar panels reduced net radiation by 44% and wind speed by 38%, leading to a cooler environment that could potentially increase crop yields.
3. Water Conservation:
Solar panels reduce water evaporation, thereby conserving water for irrigation. At Oregon State University, agrivoltaics improved water conservation by 328%, showing how this system can drastically reduce the water needed for crop irrigation in water-scarce regions.
4. Additional Income for Farmers:
Agrivoltaics can generate additional revenue streams for farmers by allowing them to sell surplus electricity. For example, in Vidarbha, a solar system generated $27,655 annually from excess electricity sold back to the grid, offering farmers a sustainable financial boost.
5. Reducing the Carbon Footprint:
By generating clean, renewable energy, agrivoltaics reduces the reliance on fossil fuels and helps cut greenhouse gas emissions. This contributes significantly to climate change mitigation.
6. Enhanced Agricultural Resilience:
Solar panels provide protection against extreme weather conditions such as hailstorms, enhancing agricultural resilience. Agrivoltaics also contributes to powering essential farm facilities like cold storage units and irrigation systems.
Incorporating agrivoltaics into Indian farming could ensure a sustainable future for agriculture while improving food security and environmental sustainability.
Highlights:
- Efficient Land Use: Simultaneous crop production and solar generation (Vidarbha case).
- Enhanced Productivity: Cooler microclimates boost yields.
- Water Conservation: 328% improvement at Oregon State University.
- Additional Income: $27,655 annually from surplus electricity (Vidarbha).
- Reduced Carbon Footprint: Helps cut GHG emissions.
- Resilience: Protects crops from extreme weather.
- Improved Irrigation: Daytime power for irrigation.

Model Answer
Benefits of Solar-Powered Irrigation Systems (SPIS) in India
1. Reduced Dependence on Monsoons and Climate Change Resilience: SPIS can mitigate the impacts of erratic monsoon patterns and climate change. These systems ensure a consistent water supply, which enhances agricultural productivity and stability. For example, farmers in Chandrapur, Jharkhand, shifted from rain-fed paddy cultivation to vegetable farming after installing solar-powered lift irrigation systems, thereby improving yields and profitability.
2. Reliable Daytime Electricity Supply: In areas with unreliable electricity, such as Vidarbha, SPIS provides a steady and regular power supply, allowing farmers to irrigate crops without depending on erratic power schedules. This reliable energy access directly impacts productivity by ensuring timely irrigation.
3. Additional Income Streams: Farmers can sell surplus electricity generated by SPIS back to the grid, creating an extra income stream. For instance, 36% of farmers in Chhattisgarh and 14% in Haryana saw a 50% increase in their annual income after installing solar water pumps.
4. Reduced Farm Subsidies: By replacing diesel and electric pumps, SPIS reduce the need for government subsidies. In 2019, electricity subsidies for agriculture in India amounted to over Rs. 1 lakh crore. The adoption of SPIS is expected to decrease these subsidies, freeing up resources for other initiatives.
5. Environmental Benefits: SPIS significantly reduce the carbon footprint of agricultural practices by replacing fossil fuel-based power sources with solar energy. The PM-KUSUM scheme alone is projected to cut down carbon emissions by up to 32 million tonnes annually.
Limitations of SPIS
1. High Initial Investment: The installation cost of SPIS can be high, making it unaffordable for small-scale farmers. This is a significant barrier to widespread adoption.
2. Maintenance and Technical Challenges: SPIS require regular maintenance and technical expertise, which may not be readily available in rural areas, hindering their effectiveness.
3. Storage and Efficiency Issues: Solar energy is intermittent, and without efficient storage solutions, SPIS may be ineffective during cloudy days or at night. The performance of these systems is also geographically dependent.
4. Water Management Concerns: Improper management of water resources could lead to over-exploitation, especially of groundwater, necessitating stringent regulations for sustainable water use.
Conclusion: Despite these challenges, SPIS hold great potential to transform Indian agriculture by promoting sustainable, climate-resilient farming. Through targeted interventions such as training programs and public-private partnerships, the barriers to adoption can be reduced, making SPIS a key driver of inclusive growth and environmental sustainability in Indian agriculture.
