Solar Plant on Agricultural Land in Tamil Nadu
Tamil Nadu farmers have a unique opportunity to earn steady income by using their land for solar power generation. Instead of depending only on crops, farmers can now combine farming with solar or even lease their land to developers for a fixed rent.
Dual-Use of Land (Agrivoltaics)
- Farmers don’t need to stop farming to install solar panels.
- With agrivoltaics, solar panels are installed at a height, allowing crops like vegetables, pulses, and medicinal plants to grow beneath.
- Benefits:
• Farmers earn double income (from crops + solar power).
• Panels provide shade, protecting crops from extreme sunlight.
• Reduces water evaporation, helping with irrigation.
This is ideal for farmers who want to continue agriculture while benefiting from solar energy.
Land Leasing Opportunities
- Farmers can lease their land to solar developers or EPC companies.
- Average lease income: ₹25,000 – ₹50,000 per acre per year.
- Advantages:
• No investment or risk for farmers.
• Long-term contracts (20–25 years) ensure stable income.
• Developers handle everything (installation, maintenance, and selling power).
This is perfect for farmers who don’t want to invest but want regular income.
Government Support (PM-KUSUM Scheme)
- Farmers can set up small solar plants on their land under the PM-KUSUM scheme.
- Benefits:
• Subsidies for installation (up to 30–40% of project cost).
• Power generated can be sold to the grid (TANGEDCO).
• Farmers get an additional source of income by becoming “solar power producers.
Key Advantages for Farmers
- Stable Income: Unlike crop yield (which depends on rain and weather), solar provides fixed returns.
- Low Risk: Leasing or subsidies reduce financial burden.
- Long-Term Benefits: Solar plants last 25+ years.
- Contribution to Clean Energy: Farmers play a role in reducing carbon emissions.
