How Much Does a 1 MW Solar Power Plant Cost in India?

The cost of 1mw solar power plant in India typically ranges from 3 to 3.5 crores (Sunkind) and is dependent upon various factors. Here is a complete breakdown of all costs for your solar power plant.

Your maximum output can be affected by some factors such as module technology, mounting structure, inverter selection, land cost, site location, civil work, electrical infrastructure, grid connectivity, power evacuation, epic scope, project development costs.

What Determines 1 MW Solar Power Plant Cost In India?

1. Solar Module Technology

Solar module technologies play a critical role in determining PV plants' maximum generation capacity, reliability, and total life cycle economics. To get optimized generation and reduce the balance of the system, use higher quality modules with greater wattage capacity.

Technologies such as TOPCon and HJT provide maximum performance and lower O&M needs to be compared to conventional PV architecture. Your cost of 1mw solar power plant in India is directly linked with your PV technology sourcing from domestic or imported sourcing, warranty terms, degradation rate, procurement volume, etc.

2. Project Location

Project location, land layout and construction efficiency are a few critical factors in your solar plant cost per MW. Your total cost is determined by transportation distance, local labor cost, construction and logistics agreement, installation timelines, project costs, and grid connectivity.

3. Ground-Mounted vs Rooftop Solar

The final determining factor for the cost of 1mw solar power plant in India is the choice between ground-mounted and rooftop solar plant based upon available space, structural conditions, project scale, and electrical requirements.

A ground mounting solar system depends upon land, foundations, piling, civil work, and extensive evacuation infrastructure, while the rooftop system is determined after proper structural assessments and a specialized solution for rooftop solar mounting.

Final solar power costs per MW are determined by installation complexity. Cable routing, accessibility, and electrical infrastructure must be evaluated carefully to determine the most technically and commercially suitable configuration.

Complete Breakdown of 1 MW Solar Power Plant Cost

Your cost of 1mw solar power plant in India depends upon the number and quality of these 8 factors.

1. Solar PV Modules

Cost = 1.4 CR

The major solar plant cost per MW depends on the solar PV module. Lower-cost conventional modules include mono PERC modules and high costs include N-type Torcon Bifacial. A module can cost more but potentially increase energy yield. If you choose a higher wattage module, then it will reduce PV count, mounting points, cabling, installation efforts, and ultimately your overall cost.

2. Solar Inverters

Cost = 15 Lakh

Inverter costs are based on which inverter your project will use: String or Central Inverters.

String Inverters: It provides a ppt distributor, modularity, and is easier to replace.

Central Inverters: It is beneficial economically for large scale utility projects.

Your project cost depends upon inverter capacity, inverter's efficiency, ppt counts, monitoring system, and battery. Battery based or hybrid systems add cost.

3. Solar Mounting Structures

Cost = 20 Lakh

The 1 MW solar power plant cost in India is determined by the solar module mounting structures used for the project. Fixed tilt ground mounting structures are often less expensive than single axis tracking systems, which include motors, controllers, mechanical components, and maintenance. Another MMS material is dependent on galvanized steel, aluminum systems, and foundation types such as piling depth, wind loads, terrain, and structural optimization for added cost.

4. DC and AC Electrical Infrastructure / BOS

Cost = 1.3 Cr

The next cost of a 1MW solar plant is electrical infrastructure cost which depends upon voltage levels.

DC Costs: DC costs include cables, connectors, string combiner boxes, junction boxes, and protection devices.

AC Costs: AC costs include LT/HT panels, transformers, switchgear, metering, and protection systems.

Your cost depends upon longer cable runs, higher voltage requirements, additional transformers, and sophisticated protection and monitoring systems.

5. Civil and Installation Costs

Cost = 15 Lakh

Civil costs solely depend upon the site's condition. Based on site, engineers may use driven piles, bored piles, RCC foundations, or other foundation systems. Installation pricing changes with uneven terrain, while roads, drainage, fencing, treaches, foundational equipment and material, labour availability, machinery, plant size, and construction complexity.

6. Power Evacuation and Grid Connectivity

Cost = 10 Lakh

Evacuation expenses can vary from a simple grid connection to a full-fledged HT transmission line, and may involve transmission lines, transformers, metering, protection, bay charges, network strengthening, permissions, and right-of-way needs. Extra site-specific charges, such as grid voltage, utility standards, and evacuation distance, can increase the project budget.

7. Land Cost

Capex Cost = Variable

Opex Cost = ₹3 - ₹5.5 per kWh (unit)

Land has the most variation in cost of 1mw solar power plant in India. A project may require the acquisition or long-term leasing of property in rural or industrial settings at various costs.

CAPEX = Your land for solar energy use and can cost based on the location, land rates, availability, terrain, land-use requirements, accessibility, and proximity to grid/transmission infrastructure

OPEX = Industry average of opex tariff only (RESCO) excluding O&M and SCADA model is ₹3.50 to ₹5.50 per kWh (unit) and at sunkind we provide ₹3 to ₹4.50 per kWh (unit).

Ground-mounted systems typically require several acres per MW, and with our greater efficiency modules and denser design, you can reduce costs dramatically. Terrain, accessibility, shadow-free areas, grading requirements, and closeness to the grid all have an impact on the effective land cost.

8. Engineering, Procurement and Construction (EPC)

Cost = 16.5 Lakh

A simple EPC package may comprise design, equipment procurement, construction, installation, testing, and commissioning; extensive packages may also include civil works, evacuation infrastructure, SCADA, paperwork, approvals, and performance guarantees. Higher-quality equipment, tighter generation guaranties, specialist engineering, and more EPC responsibilities all increase initial costs, but they can lower execution, coordination, and performance risks.

1 MW Solar Power Plant Cost In India Without Land vs With Land

Cost Components Common to Both

Typical costs associated with a solar project depend on whether the land is owned or leased. However, typical core costs that are present no matter what are: PV modules, inverter, mounting structure, electrical system, civil work, installation, EPC services etc. These are the basic project infrastructure pieces and depend on plant capacity, technology, site conditions, project equipment, etc., and on how much the project EPC package will cover.

Additional Costs When Land Is Purchased

Land acquisition and registration, documentation and legal fees, land preparation, development, leveling, fencing and access roads are all additional costs associated with land purchase, which should not be overlooked and are not part of the construction of the solar plant. Land acquisition is an important input when looking at the total investment in a project, because the overall impact is a great deal depending on location, land prices, terrain and infrastructure.

1 Megawatt Solar Power Plant Cost In India: Ground-Mounted vs Rooftop

Ground-Mounted Solar

Ground-mounted systems offer a more flexible approach to module orientation, tilt, row spacing, equipment placement and future expansion, as well as greater freedom in system design. Ground-mounted solar systems can be easily serviced and have low cost O&M as compared with roof-mounted systems.

They usually need standalone land, and it may include extra expenses associated with land development, foundations/piling, internal roads, drainage, fencing and, maybe, an extended power-evacuation infrastructure. The topography and soil conditions can greatly affect construction costs.

Rooftop Solar

Existing industrial/commercial space can be adapted for a rooftop system, thereby eliminating land acquisition or leasing expenses. Civil requirements are typically less stringent and electricity can be used relatively close to the point of generation (POG), alleviating some of the infrastructure requirements.

A 1MW rooftop system will need large appropriate roof areas and a structurally sound building. Additional constraints can be due to roof conditions, load capacity, obstructions, shading, waterproofing, access and special mounting. Modifications or maintenance to the building in the future can also disrupt the functioning of the plants.

Other Costs to Consider Beyond EPC Cost

Development Costs

Development costs relate to the efforts needed prior to construction, such as feasibility studies, site surveys, resources assessment, preliminary engineering, project development and technical consultancy. The costs are dependent on the project size and scope, as well as the location and complexity. Development work is not a large expense compared to equipment purchases, but it is a resource that can be used to mitigate technical, regulatory and commercial risks before the large capital investment is made.

Approvals and Permits

A number of Government, Land, Environmental, Electrical and Grid related approvals may be needed before construction and commissioning. The cost will cover application fee, technical studies, status clearance, documentation, liaison and professional consultancy. Their needs are dependent upon project location, capacity, ownership type and how the project will be connected to the grid and can be a significant project expense.

Financing Costs

Financial arrangements are crucial in determining the overall cost of the project, especially if financed by debt, since the interest value of the debt influences the overall cost. Interest paid during the construction of the loan; processing and banking fees; commitment fees; counselor/financial advisor fees; structuring fees. Key factors such as loan tenure, interest rate, debt-equity ratio, construction time, and lender conditions all affect the underlying costs for performing the project and the financing itself.

Insurance

The insurance safeguards the project from the loss of financial resources caused by building and operating hazards. During construction, ECI can be used to insure construction activities, such as equipment, materials, and sites. Equipment or operational policies may define risks after commissioning, if they are damage or theft, fire and other unforeseen risks. Premiums are based on project value, coverage, location, equipment and risk profile.

Operations and Maintenance

O&M costs occur during the operating life of the plant and encompass preventive and corrective maintenance, module cleaning and vegetation control, plant equipment inspection, testing and spare parts. The price depends on the type of plant, site location, equipment specification, access, and extent of installation service package. Proper O&M can minimize downtime and ensure adequate generation performance, but emissions can lead to increased losses during the life of the plant.

Monitoring and Security

Operating and securing the plants in a reliable and safe manner is enabled by monitoring and security infrastructures. Systems may encompass SCADA, Remote monitoring systems, CCTV, Alarms and access controls, Communication systems and Physical site security. The cost of the monitoring vary depending on the complexity of the monitoring design and the site conditions. The advanced performance monitoring can also detect faults, under performance, and equipment problems at an earlier stage.

ROI and Payback Period of a 1 MW Solar Power Plant
