Solar energy is a vital player in the shift towards sustainable and renewable energy sources. With advancements in technology and improved infrastructure, solar farms are becoming an increasingly popular method for large-scale energy production. If you own land and are considering leasing or selling it for a solar project, understanding the criteria is essential.


For landowners in England, Scotland, and Wales, the requirements differ based on geographic location and the type of project being pursued. Here's a guide on how to evaluate your land for solar farm potential, specific to your region.


Acreage Essentials

The first and most obvious factor to consider is the size of the land. Here at Green Switch, our requirements for solar or wind energy projects are:

  • England: 75+ acres
  • Scotland: 200+ acres
  • Wales: 250+ acres

(For battery projects located in industrial areas, the acreage required can be significantly less, given the different nature and layout of such projects. The land also needs to be close to a substation for the project to be viable.)


Location, Location, Location

While vast lands might seem perfect for a solar farm, its location plays a crucial role:

1. National Parks: These are protected areas that prioritise natural, cultural, and recreational values, making them unsuitable for large-scale solar projects.

2. Areas of Natural Beauty (AONB): Designated zones to preserve landscapes and scenic beauty, AONBs are generally not open for solar farm installations.

3. Ramsar Sites: Wetlands of international significance aim to preserve ecological balance, making them unfavourable for solar infrastructure.

4. RSPB Sites: Managed by the Royal Society for the Protection of Birds, these areas prioritise avian habitats, making them unsuitable for solar projects.

5. Special Areas of Conservation: Established under the EU's Habitats Directive, these areas protect significant habitats and species, limiting their use for renewable projects.

6. Special Protected Areas: Zones that safeguard rare or endangered bird species in Europe aren't recommended for solar installations.

7. SSSI: Sites of particular geological or biological scientific interest pose significant regulatory barriers to solar farm development.

Agricultural Grade

Solar farms can coexist with agricultural activities, and in many cases, they can even enhance the land's value and use. However, it's vital to consider the agricultural grade of the land. The land should be Grade 3 or below. Higher-grade lands, which are often more fertile and productive for crops, are generally less preferred for solar development. Lower-grade lands, which might be less suitable for intensive farming, can be perfect for solar farms.


Proximity to Infrastructure

Even if your land meets the size and location criteria, it's essential for us to consider its proximity to existing electrical infrastructure. It's more cost-effective to connect the solar farm to the grid when it's closer to substations and power lines.


Sunlight Exposure

While the UK might not be famous for its sunny weather, many regions receive ample sunlight to make solar farms viable. It's essential to consider the solar irradiance (the power received from the sun) in your area. South-facing lands without significant shading from trees or other obstacles are ideal.



If you believe your land meets the above criteria and are interested in contributing to a greener future, it's a golden opportunity. Our company is constantly on the lookout for suitable plots to develop renewable energy projects. Leasing or selling your land for solar farm development can be both financially rewarding and a meaningful contribution to sustainable energy efforts in the UK.
