Commercial solar in East Lothian

Solar in East Lothian in figures

What the figures show

Capacity in East Lothian has grown by 169% since the end of 2020, faster than the UK as a whole (69%). In 2025 alone it rose from 18.3 MW to 21.2 MW.

There are 141.9 installations for every 1,000 households, above the Scotland median of 78.4 and above the UK median of 67.0. That is 19th of 361 council areas, and 3rd of 32 in Scotland.

At 2.9 kW on average, most installations here are home-sized, so business roofs make up a small share of what is installed so far.

What a business roof in East Lothian could generate

Modelled with PVGIS for the centre of East Lothian, a south-facing roof at 30 degrees produces about 918 kWh per kWp a year. That is 295th 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

Scotland has its own planning system: National Planning Framework 4 is the national policy, and non-domestic rooftop solar is covered by the Scottish permitted development order, with conditions. A building warrant may also be needed where the roof structure is altered. Ground-mounted arrays usually need an application to East Lothian 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 Scotland page covers the operators in the region, and the Energy Networks Association postcode tool confirms yours. See G99 and DNO applications.
