Commercial solar in Highland

Solar in Highland in figures

What the figures show

Capacity in Highland has grown by 168% since the end of 2020, faster than the UK as a whole (69%). In 2025 alone it rose from 40.0 MW to 50.7 MW.

There are 116.8 installations for every 1,000 households, above the Scotland median of 78.4 and above the UK median of 67.0. That is 44th of 361 council areas, and 8th of 32 in Scotland.

At 3.8 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 Highland could generate

Modelled with PVGIS for the centre of Highland, a south-facing roof at 30 degrees produces about 800 kWh per kWp a year. That is 357th 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 Highland 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.
