Solar Power for Industrial Operations
Scalable solar solutions designed to meet the energy requirements of industries and large-scale businesses.
Industrial Solar Power Plant Cost Components
The total cost of an industrial solar power plant is divided across modules, inverters, structures, civil works, electrical infrastructure, grid connectivity and EPC services. The approximate share can vary by project size, technology and site conditions.
Solar Modules
Usually the largest component of the project cost, depending on module technology, efficiency and applicable DCR requirements.
Inverters
Includes the power conversion equipment selected according to plant capacity, system design and operating requirements.
Mounting Structure
Cost varies with rooftop or ground installation, structure height, terrain and structural requirements.
Civil Works
Includes foundations, site preparation and other civil requirements for the selected installation type.
Cables & Electrical
Covers cables, protection equipment, electrical panels and other balance-of-system components.
Grid Connection
Includes evacuation infrastructure and grid interconnection requirements, depending on the project location.
EPC & Monitoring
EPC services, insurance, SCADA, monitoring and related project management requirements.
What Changes the Cost?
DCR vs non-DCR modules
Module technology such as TOPCon and bifacial
Rooftop vs ground-mounted installation
Structure height and site conditions
Distance to the substation and evacuation requirements
Land development, SCADA scope and O&M terms
ROI Example: 1 MW Industrial Solar Power Plant
The example below shows how a 1 MW solar plant can generate savings for an industrial consumer. Actual returns depend on project cost, generation, electricity tariff, financing, O&M, degradation and applicable transmission or banking charges.

Estimated Annual Saving
₹1.05 Crore
15 lakh units × ₹7 per unit
Important: The 2.5-year figure is a simple payback calculation before O&M, module degradation, transmission or banking charges and tax benefits. Actual project payback can be different. A realistic project evaluation should consider the complete 25-year cash flow, financing costs, annual generation, degradation and all applicable charges.
Real industrial solar project payback may commonly fall within a broader range depending on the project structure, tariff and financing. Your EPC proposal should provide the detailed cash-flow and payback calculation for the specific site.
Rooftop vs Ground-Mounted vs Open Access
Choose the right solar deployment model based on your available roof or land, electricity demand, project size and grid access.
| Feature | Rooftop | Ground-Mounted | Open Access |
|---|---|---|---|
| Where | Factory roof | Your land next to the factory | Solar park or developer's land, power wheeled via grid |
| Typical size | 100 kW – 2 MW | 500 kW – 10 MW+ | 1 MW – 100 MW+ |
| Land needed | None | ~4–5 acres per MW | None (developer's land) |
| Share of your power | Limited by roof area | Large | Can be most of your daytime demand |
| Extra charges | Minimal | Minimal | Transmission, wheeling, banking and other charges (state-specific) |
| Best for | Large sheds, moderate load | Plants with spare land | High-load industries with little space |
Ground-Mounted Solar Structures
Fixed-tilt galvanised steel structures are standard; seasonal-tilt and single-axis trackers can increase generation at extra cost. Soil testing, wind-load design and drainage are important considerations for long-term 25-year performance.
Captive, Group Captive and Green Energy Open Access
Businesses can source renewable electricity through captive, group captive and green energy open access models, depending on ownership, consumption and applicable state regulations.
Captive Solar Power Plant
A plant built mainly to supply its owner's own consumption. Captive status can reduce some surcharges on power wheeled from an off-site plant.
Group Captive Solar
Several consumers jointly own a plant through a special purpose vehicle. Under the Electricity Rules, captive users must together hold at least 26% of the equity and consume at least 51% of the power generated. It lets mid-sized industries get large-plant economics without building their own.
Green Energy Open Access
Under the Green Energy Open Access Rules, consumers with a contracted load of 100 kW or more can buy renewable power from off-site plants. India's open access solar capacity reached about 27.9 GW by September 2025, led by Karnataka, Maharashtra and Gujarat.
Charges, banking and approvals vary widely by state. Your UrjaOne vendor will model the landed cost for your location.
Financing Options for Industrial Solar Projects
Choose a financing model based on your capital availability, ownership preference and long-term energy requirements.
CAPEX
Own the PlantYou invest upfront and own the plant; this can provide long-term savings and depreciation benefits.
Best for
Profitable companies with capital
RESCO / PPA
OPEX ModelA developer builds and owns the plant; you pay a fixed tariff per unit for 15–25 years.
Best for
Companies preserving capital
Group Captive
Shared PlantBuy a stake in a shared plant and consume its power without needing your own project site.
Best for
Mid-to-large industries without space
Term Loan
Bank / NBFCBank or NBFC loan for a CAPEX plant; lenders may offer dedicated renewable and MSME solar financing.
Best for
MSMEs and mid-sized units
Accelerated Depreciation
Companies that own a solar plant can generally claim accelerated depreciation, which may reduce taxable profit and improve project economics. The applicable depreciation rate and eligibility should be confirmed with your CA based on the current Income Tax rules.
Important: Confirm the current rate and your eligibility with your CA before including the tax benefit in your ROI calculation.
Bank Loans for 1 MW and Larger Plants
Lenders typically look at the promoter's financials, EPC contract, generation estimates and power offtake arrangement. UrjaOne vendors can help prepare the project report banks ask for.
