How agriPV can turn India’s farms into dual-purpose powerhouses

Why in News?

• Union Budget 2026–27 has significantly increased allocation for PM-KUSUM to ₹5,000 crore, nearly doubling the outlay and signalling a renewed push toward solarisation of agriculture through decentralised renewable systems.
• Policy consultations indicate that Agri-Photovoltaics (AgriPV) may be institutionalised under a proposed National AgriPV Mission (~10 GW component) within PM-KUSUM 2.0.
• The issue has gained importance because India faces a structural challenge of balancing large-scale solar expansion (300 GW target by 2030) with preservation of agricultural land and food security.

Conceptual clarity – What is AgriPV?

• AgriPV refers to a dual land-use system where the same agricultural land is simultaneously used for solar power generation and crop cultivation, thereby increasing overall land productivity per unit area.
• Unlike conventional solar farms that displace agriculture, AgriPV systems are designed to coexist with crops through elevated mounting structures, row spacing, or greenhouse integration, ensuring minimal disruption to farming activities.
• The approach is particularly relevant for India because over 55% of land is under agriculture, making large-scale land diversion for solar projects economically and politically challenging.

PM-KUSUM scheme  

• Launched in 2019 (MNRE) to promote decentralised solar energy in agriculture, with three components:
  • Component A: Small solar plants (up to 2 MW) on barren/fallow land.
  • Component B: Standalone solar pumps for off-grid irrigation.
  • Component C: Solarisation of grid-connected pumps.
• The 2026–27 budgetary push aims to:
  • Expand solar pump coverage
  • Integrate solar generation into farm-level energy systems
  • Move toward farmer-centric energy entrepreneurship.
• Proposed inclusion of AgriPV under KUSUM 2.0 indicates a shift from:
  • Energy access → integrated energy–agriculture production systems.

Technical models of AgriPV

• Elevated systems (2–5 metres height):
  • Allow use of tractors, irrigation equipment, and multi-cropping beneath panels.
  • Suitable for crops requiring moderate sunlight and mechanised farming.
• Row-based systems:
  • Panels placed between crop rows → optimises sunlight distribution and minimises yield loss.
  • Requires careful orientation (north-south alignment for uniform shading).
• Vertical bifacial panels:
  • Capture sunlight from both sides → useful in regions with land constraints and high albedo surfaces.
• Greenhouse-integrated systems:
  • Panels embedded in polyhouse structures → enable high-value horticulture with controlled microclimate.

Crop compatibility – agro-climatic optimisation

• Crop performance depends on shade tolerance, evapotranspiration rates, and sunlight requirements.
• Shade-tolerant crops (perform well under panels):
  • Turmeric, ginger, leafy vegetables, medicinal plants like tulsi.
• Moderate sunlight crops:
  • Tomato, onion, garlic → adaptable to partial shading.
• High sunlight crops:
  • Cultivated in panel gaps → e.g., millets (ragi, jowar).
• Region-specific examples:
  • Madhya Pradesh: tomato, onion, turmeric (semi-arid adaptation).
  • Karnataka/Maharashtra: grapes, banana, chilli (mixed cropping systems).
• Key insight:
  • AgriPV success requires location-specific design combining crop science + solar engineering.

Significance for India

Resolving land-use conflict

• Utility-scale solar requires ~4–5 acres per MW, creating competition with agriculture.
• AgriPV enables simultaneous energy and food production, reducing pressure on scarce land resources.

Enhancing farmer incomes

• Farmers gain multiple revenue streams:
  • Electricity sales (feed-in tariffs)
  • Land leasing to developers
  • Continued crop production.
• Reduces income volatility → addresses agrarian distress and climate risks.

Supporting energy transition

• Contributes to:
  • 300 GW solar target by 2030
  • Reduction in diesel-based irrigation emissions.
• Promotes distributed renewable energy systems, reducing transmission losses.

Environmental benefits

• Panel shading reduces:
  • Evapotranspiration → improves water-use efficiency (critical in water-stressed regions).
• Protects crops from:
  • Heat stress, erratic rainfall, hailstorms.
• Enables:
  • Climate-resilient agriculture under changing weather patterns.

Rural economic transformation

• Enables:
  • Cold storage, food processing, irrigation automation.
• Strengthens:
  • Rural value chains and localised energy economies.

Emerging business models

• Farmer-owned systems:
  • High autonomy but requires access to credit and technical capacity.
• FPO/cooperative aggregation:
  • Economies of scale → improved financing and bargaining power.
• Developer-led leasing model:
  • Farmers receive fixed rent or revenue share → reduces risk but limits control.
• Public sector/community model:
  • State agencies deploy systems for local energy needs and irrigation.

Key challenges

• High capital intensity:
  • Elevated mounting structures increase costs by 30–50% over conventional solar.
• Lack of standardisation:
  • No uniform design benchmarks for:
    • Panel height
    • Crop compatibility
    • Spacing norms.
• Agricultural uncertainty:
  • Improper shading can reduce yields, making farmers risk-averse.
• Regulatory ambiguity:
  • Unclear policies on:
    • Land classification (agriculture vs energy use)
    • Grid connectivity
    • Tariff structures.
• Limited empirical evidence:
  • Only ~50 pilot projects → insufficient data for large-scale scaling.
• Institutional coordination gaps:
  • Weak convergence between:
    • MNRE, Agriculture Ministry, State DISCOMs.

Way forward

• National AgriPV Mission (10 GW target):
  • Provide clear roadmap and scale pilots into national programme.
• Viability Gap Funding (VGF):
  • Offset high initial costs → improve financial viability.
• Standardisation and R&D:
  • Develop agro-climatic zone-wise:
    • Crop–panel matrices
    • Design templates.
• Regulatory reforms:
  • Clear guidelines on:
    • Land use
    • Tariff mechanisms
    • Grid integration.
• Institutional convergence:
  • Integrate AgriPV with:
    • PM-KUSUM
    • FPO schemes
    • State agriculture extension services.
• Capacity building:
  • Train farmers in:
    • Solar management
    • Crop adaptation strategies.

Prelims pointers

• PM-KUSUM → launched 2019 (MNRE).
• AgriPV → dual-use land system (solar + agriculture).
• Solar target → 300 GW by 2030.
• Net-zero target → 2070
