Commercial Solar Fields and Farms

As well as being an attractive proposition for homes and business owners who want to save on energy bills and produce clean energy, solar PV technology is increasingly becoming a popular way of profiting from larger pieces of land.

Solar Fields and Industrial Solar

More and more landowners across the UK, especially those in southern England where solar irradiation is at its highest, are installing PV panels on their land in the form of large scale (often up to several megawatts) solar fields (sometimes also called solar parks) in order to benefit from the government Feed-in Tariff (6.85p/kWh for standalone installations of up to 5MW). This can either be done through so-called ‘solar developers’, who install and maintain panels on a piece of land and then pay an annual rental fee to the owner out of the FiT income, or landowners can choose to have a PV installation company install the array and then arrange to sell the energy produced to electricity suppliers.

Such schemes are especially popular with farmers, many of whom are looking to diversify their businesses as certain farming sectors become increasingly unprofitable. In many cases solar fields offer a more reliable source of income than that offered by traditional farming, as the Feed-in Tariff export and generation payments are guaranteed for a period of 25 years. As with smaller systems, solar farms can, of course, also provide low-cost and low-carbon electricity for dwellings and other buildings.

Another increasingly popular way of establishing a solar field is to do so as part of a community or cooperative project. The first example of a community solar project in the UK is the 5MW, 30 acre Westmill solar co-op farm on the Wiltshire/Oxfordshire border, which has sold shares to members of the local community. More information on the Westmill solar co-op is available on the project’s website:

Though the exact amount of money to be earned from solar fields/parks depends largely on the amount of available land and other site-specific factors, the figures are often very attractive indeed. A common figure quoted is that developers will pay rent of around £1,000 per annum per acre of land used for a solar field installation which in many cases will be higher than the normal rent value of the land. For those landowners who chose to install the PV array themselves the income is sure to be even higher, though obviously this option presents a slightly higher financial risk.

 The Feed-in Tariff rates available to large scale solar PV arrays are available in the table above. It should be remembered that though FiT income is often tax-free for individuals, it counts as taxable income for businesses. Farmers should bear in mind that income from a standalone PV array may impact upon the tax relief offered by the Single Farm Payment, so it is a good idea to check with an accountant before proceeding with the PV installation.


Suitability for Commercial Solar Panels

Given the high upfront cost involved, the feasibility, development and planning processes required for large scale solar projects are usually lengthy and highly detailed. Substantial building or landscaping work may also be required.  As with any other solar PV installation, in order for a site to be suitable it must usually meet certain conditions, such as:

  • few obstacles (trees, hills, buildings, etc) which could cause shading issues and reduce the output of the array
  • some PV developers may set a minimum area of land for it to be financially viable
  • the proposed site must not be susceptible to floods
  • flat or south sloping ground is optimal
  • there must be access for initial construction and regular maintenance
  • planning permission is unlikely to be granted for proposed sites located in protected areas
  • there must be a local connection to the electricity grid

The solar field installation itself will comprise the PV panels, frames, inverters and cables, as well as security measures such as fencing and even cameras for some larger installations. There will also be a central control and monitoring hut.

Though regular checks of the array are required, PV panels have no moving parts, which make them reliable and durable. More information on the maintenance requirements of PV panels.
