1 MW Solar Power Plant Cost in India
Are you planning a 1 MW solar power plant in India? We provide turnkey solar EPC solutions across India, Here you’ll find everything about 1 MW solar plant cost, profit potential, ROI, land requirements, specifications, and subsidies.
What is a 1 MW Solar Power Plant?
A 1 MW (1 megawatt) solar power plant is a high-capacity solar farm designed to generate about 4,000 kWh per day or 14.4 lakh units annually.
It can power:
- Large industrial plants – textile, cement, steel, automotive
- Commercial complexes – IT parks, malls, cold storage
- Institutions – hospitals, schools, universities
- Utility-scale solar farms supplying power to DISCOMs
We handle projects nationwide, including ground-mounted and rooftop MW-scale installations.
1 MW Solar Power Plant Cost in India (2025)
The cost of setting up a 1 MW solar power plant in India generally ranges from ₹4 to ₹5 crore, varying based on technology, land, and state regulations.
Key factors influencing cost:
- Panel type (mono, poly, or bifacial).
- Mounting system (fixed or tracking).
- Local irradiation levels and grid infrastructure.

Land Requirement for a 1 MW Solar Power Plant
Setting up a 1 MW ground-mounted solar plant typically requires around 4 to 5 acres of shadow-free land with good solar exposure. However, the exact land requirement can vary based on several technical and site-related factors.
Key factors that influence the land area needed:
- Panel Efficiency: High-efficiency monocrystalline panels require less space compared to polycrystalline modules, reducing the overall land footprint.
- Mounting System: Single-axis or dual-axis tracking systems enhance energy yield but require slightly more space than fixed-tilt mounting structures.
- Site Topography: Flat and obstruction-free land minimizes civil work and reduces overall project costs. Uneven terrain may increase grading and installation expenses.
- Shading & Orientation: Adequate spacing between panel rows is essential to avoid shading and maintain optimal tilt angles.
Our team provides end-to-end support including land identification, feasibility studies, shadow analysis, and all necessary regulatory approvals. We have extensive experience in implementing MW-scale projects across Tamil Nadu, Kerala, Karnataka, Rajasthan, Gujarat, Maharashtra, and other solar-friendly states in India.
How Many Units Does a 1 MW Solar Plant Produce?
A properly designed 1 MW solar plant generates approximately:
~4,000 kWh per day
~1,20,000 kWh per month
~14,40,000 kWh per year
Actual generation varies by geographical location, panel type, and maintenance quality. For example:
Rajasthan/Gujarat: Higher annual yield due to better solar irradiance.
Kerala/TN: Slightly lower yield but higher grid-stability benefits.
Types of 1 MW Solar Power Plants
We provide customized 1 MW solar solutions in three main configurations, each designed to match your energy requirements, site conditions, and budget:
On-Grid 1 MW Solar Plant
Connected directly to the state electricity grid. Any surplus energy generated is exported to the grid and credited under the net-metering mechanism as per DISCOM regulations.
Key advantages:
- Lowest installation cost since no battery storage is required.
- Generates passive income by selling excess power back to the utility.
- Ideal for businesses and industries with reliable grid access.
Off-Grid 1 MW Solar Plant
Operates as a completely independent power system with a dedicated battery bank for energy storage.
Key advantages:
- Provides uninterrupted power even in areas with no grid connection or frequent outages.
- Suitable for remote industrial units, farms, and rural projects.
- Ensures energy independence but involves a higher upfront cost due to batteries.
Hybrid 1 MW Solar Plant
A smart combination of both on-grid and off-grid setups. It allows you to use solar power directly, export surplus to the grid, and store extra energy in batteries.
Key advantages:
- Ensures a 24×7 reliable power supply, eliminating downtime.
- Provides net-metering income and backup during grid failure.
- Ideal for mission-critical industries, data centers, and commercial facilities seeking maximum energy security.
ROI, Profit & Payback Period for 1 MW Solar Project
A 1 MW plant has a payback period of ~6–8 years with annual net profit of ₹40–45 lakh, depending on tariffs and maintenance.
Sample Income Projection:
- Annual Output: 14.6 lakh units
- Govt. Tariff (CERC average): ₹3.85/unit
- Gross Revenue: ₹56 Lakh/year
- O&M Cost: ₹8–10 Lakh/year
- Net Revenue: ₹43–45 Lakh/year
After 6–8 years, energy is virtually free for the remaining 17–19 years.
