MW Solar Power Plant Cost India 2026 — 1MW to 10MW Price Guide

MW Solar Plant Cost, Land & Generation — Quick Comparison

All figures assume a ground-mounted, fixed-tilt EPC turnkey installation at ₹35-40/watt (typical 2026 India range) with a capacity utilisation factor of 17-19%. Click any size for the full cost breakdown, FAQ, and financing guide.

Plant Size	Total Cost	Land Required
500 kW (0.5 MW)	₹1.75-2.00 Cr	2.0-2.5 acres
1 MW	₹3.50-4.00 Cr	4-5 acres
2 MW	₹7.00-8.00 Cr	8-10 acres
5 MW	₹17.50-20.00 Cr	20-25 acres
10 MW	₹35.00-40.00 Cr	40-50 acres

Financing MW-Scale Solar — CAPEX, PPA & Open Access

CAPEX (Own Investment / Bank Loan): Full ownership, highest long-term savings, and 40% accelerated depreciation under Section 32 of the Income Tax Act — but needs upfront capital (typically 70:30 debt-to-equity at 7-10.5% loan interest).

OPEX / PPA (Power Purchase Agreement): A developer builds, owns and maintains the plant; you pay a fixed, usually-lower-than-grid per-unit rate with zero upfront investment.

Open Access / Group Captive: Large consumers (typically above 1MW connected load, varies by state) can buy power from an offsite plant through the grid, paying wheeling, banking, and cross-subsidy surcharge charges. Group captive requires at least 26% equity and 51% self-consumption of the plant's generation.

Frequently Asked Questions — MW Solar Power Plants

What is a megawatt (MW) solar power plant?

A megawatt (MW) solar power plant is a large solar installation with a capacity of 1,000 kW or more — typically ground-mounted, though large commercial/industrial rooftops can also reach 1MW+. MW-scale plants are used for open access, group captive, PPA-based commercial supply, or utility-scale power generation, unlike home rooftop systems which are usually 1-10kW.

How much does a 1MW solar plant cost in India in 2026?

A 1MW ground-mounted solar plant costs approximately ₹3.50-4.00 crore in India in 2026 (about ₹35-40 per watt turnkey EPC cost), needing roughly 4-5 acres of land and generating about 14.8-18.1 lakh units per year.

How much land is needed per MW of solar power?

A fixed-tilt, ground-mounted solar plant needs approximately 4-5 acres of flat, unshaded land per MW of capacity in India. High-density layouts with modern high-wattage modules can bring this down slightly; tracker-based systems typically need more space.

Is there a subsidy for MW-scale solar plants in India?

No — the PM Surya Ghar subsidy (up to ₹78,000) applies only to small residential rooftop solar systems, not MW-scale commercial or industrial plants. MW-scale plants instead benefit from 40% accelerated depreciation under the Income Tax Act, GST input tax credit, and (for open access/group captive projects) exemption from certain cross-subsidy surcharges in some states.

Which is cheaper for a large solar plant — CAPEX or PPA?

CAPEX (owning the plant via cash or loan) gives the lowest per-unit cost of electricity over the plant's 25-year life and lets you claim 40% accelerated depreciation, but needs upfront capital. A PPA (Power Purchase Agreement) needs zero upfront investment and is simpler, but the effective long-term cost per unit is usually higher than owning the plant outright.
