Land Required for 1 MW Solar Power Plant in India

How much land does a 1 MW solar power plant need in India?

A 1 MW ground-mounted solar plant on crystalline-silicon modules needs roughly 3-5 acres (about 1.2-2 hectares). Solar Energy Corporation of India's own FAQ puts it at around 5 acres per MW for crystalline-silicon technology, while Telangana's renewable energy development agency budgets 3-3.5 acres per MW under PM-KUSUM Component A — the modern range reflects today's higher-efficiency modules.

TL;DR: Plan on 3-5 acres per MW for a fixed-tilt, ground-mounted crystalline plant: SECI's published rule of thumb is about 5 acres per MW, and TGREDCO's PM-KUSUM guidance is 3-3.5 acres per MW (1.5-1.75 acres for 0.5 MW, 7-8 acres for 2 MW). Land goes mostly to row spacing, roads, inverter stations and the switchyard, not to the panels themselves — 1 MW of modules covers well under an acre of glass. Confirm whether a quote is for MW AC or MWp DC, because an oversized DC array needs proportionally more land.

Where the range comes from

Two official anchors bracket the answer:

• SECI, ~5 acres per MW. The Solar Energy Corporation of India's FAQ states: around 5 acres of land is required for a 1 MW SPV plant with crystalline-silicon technology, slightly more for thin film (SECI FAQ). This has been the Indian solar sector's long-standing planning figure.
• TGREDCO, 3-3.5 acres per MW. Telangana Renewable Energy Development Corporation's PM-KUSUM FAQ answers with 1.5-1.75 acres for a 0.5 MW plant, 3-3.5 acres for 1 MW and 7-8 acres for 2 MW (TGREDCO FAQ).

The gap between 3 and 5 acres is not a contradiction — it is module efficiency and design discipline. A megawatt of modules at 16% efficiency covers about 6,250 sq m of glass; at 22% efficiency it covers about 4,545 sq m, roughly 27% less, and row spacing shrinks with it. Older planning figures assumed the lower-efficiency polycrystalline modules of the 2010s. Most of the land in either case is not under panels at all: it is the row-to-row spacing that prevents one row shading the next on winter mornings, plus internal roads, inverter and transformer stations, a switchyard and boundary setbacks.

Land required by plant size

Capacity scales linearly, so the two columns simply multiply — but site shape does not. A long, narrow or sloped parcel wastes row pitch and can push a nominally five-acre megawatt higher. PM-KUSUM Component A, the central scheme that funds plants from 500 kW to 2 MW on farmer and rural land, is covered in our PM-KUSUM guide.

MW AC versus MWp DC: why quotes differ

Land is consumed by panels, and panel count is set by the DC capacity (MWp), while grid connections and PPAs are expressed in AC capacity (MW). Many plants today install more DC than the inverter rating — a deliberate design choice explained in our DC/AC ratio and clipping guide — so a 1 MW AC project can carry meaningfully more than 1 MWp of modules, and proportionally more land. Before comparing two acreage quotes, ask which capacity the number refers to.

What the land must fit besides panels

The array field is only part of the site. Budget space for:

• Row spacing (pitch). Sized so the row in front does not shade the row behind at the winter solstice — the single largest land use.
• Internal access roads. Wide enough for module trailers and cleaning equipment, plus a perimeter road.
• Inverter and transformer stations. Pads distributed through the array.
• Switchyard. A 1-5 MW plant typically connects at 11 kV or 33 kV, and the switchyard and bay need their own footprint.
• Setbacks, fencing and drainage. Boundary clearance and stormwater handling.

Fixed tilt, trackers and agrivoltaics

Mounting choice moves the number. Fixed-tilt is the default and the basis of the figures above. Single-axis trackers rotate the rows to follow the sun, which raises generation but needs wider row spacing, so expect trackers to use somewhat more land per MW than fixed tilt — the trade-off is more energy from the same capacity. Agrivoltaics raises the structure high enough to farm underneath; it uses the most land per MW of any configuration but the land keeps producing a crop, which changes the comparison entirely — our agrivoltaics guide covers the Indian schemes and pilots.

Rooftop instead of land

If the plant feeds your own factory, the cheapest acreage is the roof you already own. A 1 MW rooftop plant needs roughly 10,000 sq m of shadow-free roof — our rooftop area guide gives the per-kW arithmetic, and our rooftop versus ground-mount comparison weighs the two routes for industrial buyers. For a 500 kW rooftop, Sun Wave's published reference rate is ₹22,000/kW ex-GST (final price after site survey). Where no land or roof is available near the load, floating solar is the remaining alternative.

Checks before you buy or lease land

• Title and classification. Verify clean title and the parcel's recorded land use; agricultural land generally needs conversion through the state revenue authority before construction, and the process differs by state.
• Grid distance. Land is cheap far from a substation, and transmission then is not — a parcel within practical reach of an 11/33/66 kV line is worth more than a cheaper one that is not.
• Terrain and shading. Slope, watercourses, rocky patches and HT-line corridors are acreage you pay for but cannot build on.
• Scheme fit. For 500 kW-2 MW plants on rural land, PM-KUSUM Component A is the structured route; our guide covers eligibility and the application flow.

Frequently Asked Questions

How many acres are needed for a 1 MW solar power plant?

About 3-5 acres for a fixed-tilt, ground-mounted plant on crystalline-silicon modules. SECI's published rule of thumb is around 5 acres per MW; Telangana's TGREDCO budgets 3-3.5 acres per MW for PM-KUSUM Component A plants.

Is 3 acres enough for a 1 MW solar plant?

Only with high-efficiency modules and a tight, well-shaped site. As a budget, plan on 4-5 acres per MW so the layout has room for roads, a switchyard and sensible row spacing; a parcel with no spare room is a false economy over a 25-year plant life.

How much land does a 500 kW solar plant need?

Roughly 1.5-2.5 acres: TGREDCO's PM-KUSUM guidance for 0.5 MW is 1.5-1.75 acres, and scaling SECI's 5-acre-per-MW rule gives about 2.5 acres.

Can a solar plant be built on agricultural land in India?

Generally yes, after land-use conversion through the state revenue authority, since solar plants are a non-agricultural use. PM-KUSUM Component A is designed for agricultural and rural land specifically, which is why the state KUSUM agencies publish the per-MW acreage guidance.

How much land does a 1 MW rooftop solar plant need?

None beyond the roof itself — a 1 MW rooftop array needs roughly 10,000 sq m of shadow-free roof area, about 10 sq m per kW. Our rooftop area guide has the per-kW and per-MW arithmetic.

Do solar trackers change the land requirement?

Yes. Single-axis trackers need wider row spacing so rotating rows do not shade each other, so a tracker plant uses somewhat more land per MW than a fixed-tilt plant. The compensation is higher generation from the same rated capacity — a land-for-energy trade-off to price in the feasibility stage.
