The short answer
Commercial solar works in Scotland: generation per kWp is lower than in England, but high commercial electricity prices keep payback attractive and Business Energy Scotland offers free advice and support. Two network operators cover the country. We match you with a vetted installer for a free site survey.
Picking a commercial solar installer is the step where businesses most often get a poor deal — the Scotland market has plenty of firms, and quality varies. This page covers what is specific to going solar across Scotland; our guide to choosing an installer sets out the full vetting criteria, and our quote-comparison checklist shows what a good quote must contain.
Who runs the grid across Scotland?
Scotland has two distribution network operators: SP Energy Networks covers central and southern Scotland, and Scottish & Southern Electricity Networks (SSEN) covers the north. Your installer applies to the relevant one for the grid connection (a G99 application for exporting systems, typically 8–12 weeks).

How much will a roof generate in Scotland?
Scotland gets fewer peak-sun hours than England, so generation per kWp is lower than the UK average of around 950 kWh per kWp per year — though long summer days help. High commercial electricity prices mean the savings per unit are strong regardless.
The number that matters most is how much you use during daylight: every unit you generate and use yourself displaces grid power at 25–30p. Our payback and ROI guide works through the returns, or get a figure for your own roof with the calculator below.
Are there solar grants for Scotland businesses?
Business Energy Scotland, funded by the Scottish Government, offers free advice and an interest-free SME Loan of up to £100,000 for energy measures. Note that solar PV is not currently eligible for that loan, so Scottish businesses lean on the UK-wide tax reliefs — the £1m Annual Investment Allowance applies in Scotland exactly as it does in England. Scotland also excludes renewable generation plant, including rooftop solar and batteries, from rateable value from 1 April 2023 until 31 March 2035, so installing panels won't raise your non-domestic rates bill. Terms change, so check the latest position.
On top of any local scheme, every UK business can use the £1m Annual Investment Allowance to deduct the cost from profits — worth roughly 25% of the project back at the 25% corporation tax rate. Our grants and tax relief guide has the national picture.
The Scotland installer market
Scotland is served by a mix of Scottish installers and national firms that cover the country, with the deepest fields around Glasgow, Edinburgh, Aberdeen and the central belt — more remote sites in the Highlands and islands have fewer local options, so travel costs can show up in quotes. Vetting on certification, insurance and track record matters as much here as anywhere, and local knowledge of the two network operators is a genuine plus.
Planning permission in Scotland
Planning is devolved, and since 24 May 2024 Scotland's permitted development rights for rooftop solar have been among the most generous in the UK: the old 50 kW cap was removed, so most commercial rooftop systems of any size need no planning application, and flat-roof systems are permitted provided panels protrude no more than one metre. Listed buildings and World Heritage Sites still require permission, and conditions apply on principal elevations in conservation areas.
Full detail is on our commercial solar planning permission guide.

Frequently asked questions
Who runs the electricity grid in Scotland?+
Two operators: SP Energy Networks covers central and southern Scotland, and SSEN (Scottish & Southern Electricity Networks) covers the north. Your installer submits the grid connection (G99) application to the relevant one for any exporting system; approval usually takes 8–12 weeks.
Is solar worth it in Scotland?+
Yes, for most businesses with daytime electricity use. Generation per kWp is lower than in England, but commercial electricity prices are high so each unit you self-generate saves more. Payback is typically a little longer than the UK 4–7 year average, and Business Energy Scotland offers free advice to help you plan.
Are there solar grants or loans for Scottish businesses?+
Business Energy Scotland, funded by the Scottish Government, offers free advice and an interest-free SME Loan for energy measures — though solar PV is not currently eligible for that loan. The £1m Annual Investment Allowance still returns roughly 25% of project cost in tax relief, and renewable plant is excluded from Scottish non-domestic rates until 31 March 2035. Confirm current scheme terms before relying on them.
Do I need planning permission for commercial solar in Scotland?+
Usually not. Since 24 May 2024 Scotland's permitted development rights cover most rooftop solar with no upper size cap — the old 50 kW limit was removed — including flat-roof systems where panels protrude no more than one metre. Listed buildings and World Heritage Sites still need permission, and conservation areas carry conditions on principal elevations. Building regulations apply in all cases.
