Commercial solar in South Holland

Solar in South Holland in figures

What the figures show

Capacity in South Holland has grown by 178% since the end of 2020, faster than the UK as a whole (69%). In 2025 alone it rose from 93.8 MW to 98.1 MW.

There are 124.8 installations for every 1,000 households, above the East Midlands median of 75.8 and above the UK median of 67.0. That is 34th of 361 council areas, and 2nd of 35 in East Midlands.

The average installation is 19.3 kW, about twice a typical home system, so larger commercial, farm and ground-mounted systems make up a good share of the capacity.

What a business roof in South Holland could generate

Modelled with PVGIS for the centre of South Holland, a south-facing roof at 30 degrees produces about 1,037 kWh per kWp a year. That is 69th of 361 council areas; the UK median is 998 kWh.

Same sums as our commercial solar calculator: illustrative, not a quote. East- or west-facing roofs, shading and how much power you use in daylight all move these figures, and a company paying corporation tax can usually shorten the payback with capital allowances. See the cost guide for price ranges by system size.

Planning and grid connection

South Holland follows the national planning rules for England. Permitted development rights for non-domestic rooftop solar were widened in December 2023, including removal of the old 1 MW limit, but conditions still apply, especially for listed buildings and conservation areas. Ground-mounted arrays and carports usually need an application to the council, or to a national park authority inside a national park. Our planning permission guide sets out the conditions.

Most commercial systems need G99 approval from the local network operator before they are switched on. The operator follows the postcode rather than the council boundary: our East Midlands page covers the operators in the region, and the Energy Networks Association postcode tool confirms yours. See G99 and DNO applications.
