Land for small solar farms

Open land of 1.6 to 11 ha outside towns, on a road and within 2 km of a primary substation: the size a 1 to 5 MW scheme needs, connecting at 11 kV. Flood zone 3 and protected landscapes are left out.

What the search looks for

Each line is a filter on the map, so you can widen or tighten any of them.

Open the search
  1. 1.6 to 11 ha of open land outside towns
  2. Within 2 km of a primary substation
  3. Slope under 5°
  4. Best farmland ranked lower
  5. On a road
  6. Out of flood zone 3 and protected landscapes
  7. Not water, green space, an airfield or an existing solar or wind farm

In this order: the most megawatts the land and the grid can both take first, then nearest a substation first.

On every site

The grid
The nearest primary substation by name, the distance to it, and the spare generation and demand capacity its network operator publishes.
The land
Slope, farmland grade, tree cover and flood zones, with solar yield and mean wind speed for every parcel.
What is there already
Solar, wind and battery schemes on or near the land with their status, and national infrastructure projects that take in part of it.

Why these rules

National Policy Statement EN-3 (2025, in force since 6 January 2026), paragraph 2.10.9: a solar farm currently needs 1.6 to 2.25 ha (4 to 5.6 acres) for each MW, so 1 to 5 MW is about 1.6 to 11 ha; slope and frontage are common practice; small schemes connect at 11 kV, within about 2 km of a primary substation. Woodland is left out.

Best and most versatile farmland is not left out: national policy steers solar away from it where possible (EN-3), so it ranks below poorer land and is flagged on each site; land over half grades 1 and 2, over a fifth under trees, or over 30% inside a national infrastructure project is left out.
