Overview
- Agrivoltaics combines agricultural activities with solar power generation on the same land, improving land-use efficiency.
- It can diversify farmers’ incomes, reduce energy costs and support rural employment.
- It offers environmental benefits through renewable energy generation, potential water conservation and reduced heat stress for suitable crops.
- Its wider adoption requires affordable financing, crop-specific designs, research support and farmer participation to balance energy generation with food security.
Why in the News?
Agrivoltaics is gaining importance in the context of the World Conference on Agrivoltaics at Bharat Mandapam, New Delhi, which discussed the potential of combining solar power generation with agricultural activities.
News in Brief
- Agrivoltaics combines solar photovoltaic (PV) installations with agricultural activities on the same land, enabling farmers to generate electricity while continuing cultivation.
- The PM-KUSUM scheme has already demonstrated the potential of decentralised solar energy in agriculture.
- Agrivoltaics can provide farmers with an additional source of income while improving resilience against heat stress, drought and other weather-related challenges.
- The technology requires suitable crop selection, efficient irrigation, appropriate solar panel spacing and coordination among farmers, researchers and government institutions.
What is Agrivoltaics?
- Agrivoltaics refers to the simultaneous use of land for agriculture and solar photovoltaic power generation.
- Solar panels are installed above or alongside crops, allowing agricultural activities to continue beneath or between them.
- The system can support crop cultivation, livestock grazing and electricity generation, depending on the design.
- It offers an opportunity to improve land-use efficiency by combining food production with renewable energy generation.
- Agrivoltaics can help address the competing demands for agricultural land and renewable energy infrastructure.
Economic benefits for farmers
Agrivoltaics can diversify rural incomes and reduce farmers’ dependence on agricultural returns alone.
- Additional income: Farmers can earn revenue by selling surplus electricity or leasing land for suitable solar installations.
- Reduced input costs: Solar power can reduce expenditure on electricity and irrigation, depending on the system and its financing.
- Income stability: Revenue from electricity generation may help offset fluctuations in crop prices, weather conditions and agricultural production.
- Rural employment: Installation, maintenance and operation of solar systems can create employment opportunities in rural areas.
However, the benefits depend on installation costs, financing arrangements, electricity purchase agreements and the distribution of revenue between farmers and developers.
Environmental and Agricultural Benefits
- Agrivoltaics can support both climate adaptation and mitigation.
- Microclimate regulation: Partial shade can reduce excessive solar radiation and heat stress for suitable crops.
- Water Conservation: Reduced evaporation may lower irrigation requirements under appropriate conditions.
- Renewable energy: Solar power reduces dependence on fossil fuels and can lower greenhouse gas emissions.
- Land-use efficiency: The same land supports agricultural production and electricity generation.
- Limitations;
- Excessive shading can reduce crop yields.
- The impact varies with crop type, panel height, spacing, climatic conditions and agricultural practices.
- Agrivoltaics is therefore not equally suitable for every crop or region.
Importance of Crop Selection and Technology
- Successful implementation requires scientific planning rather than simply installing solar panels over farmland.
- Key considerations include:
- Crop selection: Shade-tolerant crops may be more suitable than crops requiring high levels of direct sunlight.
- Solar panel configuration: Panel height, spacing and orientation should balance electricity generation with sunlight requirements for crops.
- Irrigation and nutrients: Efficient irrigation and appropriate nutrient management are essential for maintaining productivity.
- Technological innovation: Improved solar designs, monitoring systems and agricultural research can help optimize land productivity.
- Research institutions such as the Indian Council of Agricultural Research (ICAR) can support the identification of suitable crops and region-specific agrivoltaic models.
PM-KUSUM and Agrivoltaics
- The Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) promotes solar energy adoption in the agricultural sector.
- Its major components include:
- Component A: Decentralized, grid-connected renewable power plants, including solar power plants.
- Component B: Stand-alone solar agricultural pumps.
- Component C: Solarization of grid-connected agricultural pumps, including feeder-level solarization.
- PM-KUSUM can support the broader transition towards solar-powered agriculture.
- However, the scheme and agrivoltaics are not identical.
- Agrivoltaics specifically focuses on combining agricultural production with solar power generation on the same land.
Institutional and Research Support
- The development of agrivoltaics requires cooperation between agricultural scientists, renewable energy institutions, governments and private enterprises.
- ICAR: Supports agricultural research, crop suitability assessments and region-specific farming practices.
- National Institute of Solar Energy (NISE): Contributes to solar energy research and technology development.
- Government institutions: Can facilitate pilot projects, standards, financing and policy support.
- Private sector: Can contribute investment, technology, installation and maintenance services.
- Farmers and local institutions: Help assess practical outcomes and ensure that project designs meet local needs.
- Field trials and long-term assessments are essential to determine the effects on crop yields, soil conditions, water use and farmers’ incomes.
Challenges in adopting agrivoltaics
- Despite its potential, agrivoltaics faces several challenges.
- High initial investment in solar installations and supporting infrastructure can make adoption difficult for small and marginal farmers.
- Crop yield uncertainty remains a concern, as poorly designed systems may reduce sunlight availability and agricultural productivity.
- The unequal distribution of benefits may limit farmers’ returns when project agreements favor developers.
- Technical constraints require solar panel designs to account for local crops, soil conditions, rainfall and irrigation needs.
- Inadequate maintenance facilities, technical expertise and grid connectivity can also affect implementation.
- Further, projects must ensure that solar energy generation does not displace agricultural activities or compromise food security and long-term land productivity.
Way Forward and Conclusion
Agrivoltaics should be promoted through region-specific models, affordable financing, farmer participation and research on suitable crops. Better grid connectivity and pilot projects can help assess its impact on agricultural productivity and farmers’ incomes.
Agrivoltaics can support India’s renewable energy transition while diversifying rural incomes. Its success depends on balancing solar power generation with food security, sustainable agriculture and farmers’ interests.
