1-Acre Solar Farm Profit in India: A Complete Guide
Introduction
Investing in a 1-acre solar farm in India presents a promising opportunity for sustainable income, leveraging the country’s abundant sunlight and supportive government policies. With rising electricity demand and favorable incentives for renewable energy, solar farming is an attractive investment option.
This guide delves into the potential profits, costs, and key considerations for establishing a solar farm on a 1-acre plot.
Understanding the Potential of a 1-Acre Solar Farm
A 1-acre solar farm in India can typically accommodate a solar power plant with a capacity ranging from 220 kW to 250 kW, depending on the efficiency of the solar panels and location. This capacity translates to an average daily energy production of approximately 890 kWh, amounting to around 313,900 kWh annually.
Factors Affecting Solar Farm Productivity:
- Geographic Location: Higher solar irradiation areas yield more energy.
- Solar Panel Efficiency: Modern high-efficiency panels generate more power.
- Land Orientation & Layout: Properly positioned panels maximize sunlight exposure.
- Weather Conditions: Less cloud cover ensures consistent energy production.
Financial Overview: Costs and Revenue
Initial Investment
The estimated cost of setting up a 1-acre solar farm in India is approximately ₹1 crore (around $120,000). This includes solar panels, inverters, mounting structures, protective gear, SCADA systems, and installation costs.
Estimated Cost Breakdown:
- Solar Panels (220 kW – 250 kW): ₹66 lakhs
- Solar Inverters (220 kW): ₹22 lakhs
- Combiners and Junction Boxes: ₹5 lakhs
- Protective Gear Arrangement: ₹3 lakhs
- SCADA and Data Logger System: ₹2 lakhs
- Erection Cost: ₹2 lakhs
Note: Costs may vary based on location, equipment quality, and supplier rates.
Revenue Generation
A solar farm generates revenue by selling electricity to the local grid through Power Purchase Agreements (PPAs). Assuming an average tariff rate of ₹3.85 per unit, the estimated annual income would be:
- Total Annual Energy Output: 313,900 kWh
- Tariff Rate per Unit: ₹3.85
- Total Annual Income: ₹12,09,515
Profitability and Return on Investment (ROI)
After accounting for annual maintenance costs, the net annual income is substantial. Considering the ₹1 crore investment, the payback period is around 8 to 10 years. Once the initial investment is recovered, the majority of revenue turns into profit, as solar farms have minimal operational costs beyond maintenance.

Key Considerations for Investors
1. Land and Location Requirements
A 1-acre plot is sufficient for a 220 kW to 250 kW solar installation. The land should be:
- Flat and Unshaded: Obstacles like trees and buildings reduce efficiency.
- Close to Grid Infrastructure: Minimizes transmission losses and connection costs.
- Easily Accessible: Reduces logistics and maintenance difficulties.
2. Government Policies and Incentives
The Indian government supports solar energy projects with various incentives and subsidies, such as:
- Capital Subsidies: Up to 30% subsidy for eligible solar projects.
- Accelerated Depreciation: Investors can claim 40% depreciation on solar equipment.
- Renewable Energy Certificates (RECs): Earn tradable credits for every unit generated.
- Net Metering: Permits extra electricity to be traded back to the grid.
3. Technological Advancements
Investing in high-efficiency solar panels and inverters can increase output and reduce the payback period. Some key technological improvements include:
- Bifacial Panels: Capture sunlight from both sides, increasing energy generation.
- Tracking Systems: Adjust panel angles to follow the sun, boosting efficiency.
- Energy Storage Systems: Store excess energy for use during peak demand hours.
Maintenance and Operational Costs
A solar farm requires minimal maintenance compared to other energy sources. Key maintenance tasks include:
- Cleaning Panels: Regular cleaning prevents dust accumulation, which can reduce efficiency.
- Inspection of Inverters and Cables: Ensures smooth electricity transmission.
- Software Monitoring: SCADA systems track performance and detect issues.
Annual maintenance costs range between ₹50,000 – ₹1,50,000, depending on the scale and technology used.
Long-Term Benefits of Solar Farming
1. Steady and Passive Income
Once the initial investment is recovered, solar farms generate consistent passive income for over 25 years.
2. Environmental Benefits
Solar energy is clean and sustainable, reducing carbon footprints and dependence on fossil fuels.
3. Increasing Demand for Renewable Energy
As electricity prices rise and the government pushes for net-zero emissions, solar energy will remain a profitable and future-proof investment.
Conclusion
Setting up a 1-acre solar farm in India is a lucrative long-term investment. With a ₹1 crore initial investment, investors can expect stable annual returns exceeding ₹12 lakh, leading to a payback period of 8–10 years.
By leveraging government incentives, high-efficiency technology, and strategic location planning, investors can maximize profitability while contributing to a cleaner and greener future.
Frequently Asked Questions (FAQs)
Q1: What is the lifespan of solar panels in a solar farm?
A1: Most solar panels come with a 25-year performance warranty, but they can continue to generate electricity beyond this period, with slightly reduced efficiency.
Q2: Can I get financing for a solar farm in India?
A2: Yes, many banks and financial institutions offer solar loans at competitive interest rates, and government subsidies further ease the financial burden.
Q3: How does the location affect solar farm profitability?
A3: Areas with higher solar irradiation generate more electricity, increasing revenue. Locations near grid infrastructure also reduce transmission costs.
Q4: What are the maintenance costs of a 1-acre solar farm?
A4: Annual maintenance costs range from ₹50,000 to ₹1,50,000, including panel cleaning, inverter inspections, and system monitoring.
Q5: Can I expand my solar farm beyond 1 acre?
A5: Yes, expansion is possible if additional land is available and the local grid can handle the increased energy output. It’s advisable to plan for expansion from the start.
