Agrivoltaics in India: A Data-Driven Approach to Dual Land Use

India's renewable energy expansion is accelerating, but one structural constraint continues to limit scale: land availability.

More than 40 percent of large-scale solar installations in India are already located on agricultural land, creating increasing competition between food production and energy generation.

At the same time, agriculture supports a significant portion of the population and remains highly vulnerable to climate variability.

Agrivoltaics in India, the co-location of solar infrastructure and agriculture, has emerged as a potential solution to this land-use conflict.

What is Agrivoltaics?

Agrivoltaics refers to the integration of solar photovoltaic systems with crop cultivation on the same land parcel.

Unlike conventional solar farms, agrivoltaic solar plants are designed with:

• Elevated module structures
• Optimized spacing
• Controlled light distribution

This allows sunlight to be shared between energy generation and plant growth, rather than competing for it.

Why Agrivoltaics Matters in India

1. Land Constraint is Becoming Critical

India has an estimated 748 GW solar potential, but scaling this requires significant land resources.

With agriculture already occupying a major share of land, expanding solar without disrupting farming is becoming increasingly difficult.

2. Large Untapped Agrivoltaic Potential

India has:

• Approximately 170 million hectares of cultivated land
• Around 6 million hectares technically suitable for agrivoltaics

This translates to a potential capacity of approximately 3.89 TWp, capable of generating over 5,600 TWh annually, far exceeding projected electricity demand.

3. Growing Market Momentum

The agrivoltaics market in India is projected to grow at a CAGR of approximately 11.5 percent through 2032, indicating increasing commercial interest.

Performance and Productivity: What the Data Shows

Higher Land Productivity

Agrivoltaics improves total land output through dual use.

• Studies show 150 to 160 percent land-use efficiency compared to single-use systems.
• Land Equivalent Ratio often exceeds 1.5, meaning combined output is significantly higher than separate systems.

Crop Yield Impact

The impact on crops is crop-specific and condition-dependent:

• Yield increases of up to 30 percent have been observed in some cases.
• Shade-tolerant crops such as leafy vegetables and berries perform better under panels.
• Poor design or unsuitable crops can reduce yields due to light limitations.

Water Efficiency Gains

Partial shading from panels can:

• Reduce evaporation
• Improve soil moisture retention
• Lower irrigation requirements

Studies indicate over 30 percent reduction in water usage in certain agrivoltaic setups.

Solar Performance Benefits

Microclimate effects created by crops can help:

• Lower panel temperature
• Improve efficiency and output stability

Additionally, integrated systems have demonstrated 60 to 70 percent higher total productivity, considering both energy and crops combined, in field trials.

Key Benefits of Agrivoltaics in India

1. Dual Revenue Streams

Landowners generate income from:

• Electricity generation
• Agricultural produce

This reduces dependency on seasonal farming income.

2. Climate Resilience

Agrivoltaics helps mitigate:

• Heat stress
• Water scarcity
• Extreme weather impact on crops

3. Land Optimization

Instead of allocating land separately, agrivoltaics enables multi-functional land use, improving economic output per acre.

Challenges and Limitations

Despite strong potential, agrivoltaics in India is not universally applicable.

1. Higher Capital Costs

Elevated mounting structures and customized layouts increase upfront investment.

2. Design Sensitivity

System performance is highly dependent on design parameters such as panel height, spacing, and layout. Poor design can negatively impact both energy generation and crop growth.

3. Crop Compatibility Constraints

Not all crops are suitable for agrivoltaic systems, and poor selection can reduce yields.

4. Policy and Ecosystem Gaps

• Limited large-scale deployments
• Evolving policy frameworks
• Lack of standardized design guidelines

Best Crops for Agrivoltaics in India

Based on research and field observations, suitable crops include:

• Potatoes
• Spinach and coriander
• Garlic
• Certain legumes

Globally, crops such as lettuce, tomatoes, and berries have also shown strong compatibility with agrivoltaic systems.

Investment Feasibility

Agrivoltaics is most viable when:

• Land size is large and contiguous, typically 10 acres or more
• Long-term returns are prioritized
• Projects are designed with engineering and agricultural integration

Short-term or poorly designed projects carry higher risk due to cost and yield uncertainty.

Current Status of Agrivoltaics in India

Agrivoltaics remains at an early but accelerating stage:

• Over 25 pilot projects and demonstration sites are operational or planned
• Government schemes such as PM-KUSUM are supporting solar adoption in agriculture

Adoption is expected to grow as:

• Costs reduce
• Design improves
• Awareness increases

From Concept to Execution

At SLNKO, we see agrivoltaics as a practical step toward improving land productivity rather than just an emerging concept.

Its success depends on how well solar design and agricultural planning are integrated at the ground level.

For projects to be viable, execution must be driven by site-specific design, not standard templates.

Conclusion

India's energy transition will not be defined only by how much solar capacity is installed, but by how efficiently land is utilized.

Agrivoltaics in India offers a measurable advantage:

• Up to 150 to 160 percent higher land-use efficiency compared to single-use systems
• Potential crop yield improvements of up to 20 to 30 percent in optimized conditions
• Water savings of 20 to 30 percent or more due to reduced evaporation and improved soil moisture
• A theoretical potential of approximately 3.8 terawatts capacity using suitable agricultural land

These numbers highlight a clear shift from land consumption to land optimization.

However, outcomes are highly dependent on design quality, crop selection, and execution.

Done right, agrivoltaics is not just an alternative approach. It is a high-efficiency model for future-ready solar development, where energy and agriculture can coexist without compromise.
