An independent guide for homes in Scotland
Solar in Scotland is not English solar with colder weather. The funding is different, the planning law is different, tenements have their own rules, and the east coast gets more from a roof than many people expect. This guide sets out the Scottish facts, each one sourced, before anyone tries to sell you anything.
kWh a year per kW of panels at the best angle (PVGIS 5.3)
Place-by-place yield · PVGIS for twelve Scottish places
Choose the nearest place, the way your roof faces and a system size. Figures are PVGIS 5.3 long-run estimates at a 35° pitch with 14% system losses: an indicative result for comparison, not a survey of your roof.
3,612 kWh a year
About 144% of the 2,500 kWh a typical home uses each year (Ofgem). Part is used at home and part exported.
Indicative cost at the Scotland average: £7,800 (DESNZ 2025/26 mean per kW × size; our arithmetic, quotes vary).
Every place, same roof: kWh a year per kW

Many solar adverts in Scotland still talk about grants. The honest position on 3 November 2026 is simpler: households that can pay get no grant for solar PV, and the scheme that once helped has closed to it.
The Home Energy Scotland Grant and Loan stopped funding solar PV and battery storage for applicants sent a link after 6 June 2024. Today it offers a loan of up to £5,000, with no grant, only for hybrid PV-T panels and solar water heating (Home Energy Scotland). The effect is visible in the Scottish Government's own figures: solar PV measures it funded fell from 3,368 in 2023–24 to 371 in 2025–26 (Heat in Buildings progress report 2026).
Warmer Homes Scotland, delivered by Warmworks, is for owners and private tenants on qualifying benefits or with specific health or age needs, in homes with a poor energy rating. It recorded 1,369 solar PV or battery measures in 2025–26 (Home Energy Scotland). Council Area Based Schemes, funded with £64m in 2025/26, focus on fuel-poor areas and mostly fund wall insulation, but solar appears in their figures too (gov.scot).
Everyone gets 0% VAT on installed solar and batteries until 31 March 2027 (HMRC), and the Smart Export Guarantee applies across Great Britain, so a supplier must offer something for the power you export (Ofgem).
The government publishes what MCS-certified solar actually cost, region by region. For Scotland in 2025/26 it covers 28,369 Scottish installations (DESNZ, published 28 May 2026). Systems up to 4 kW averaged £1,944 per kW and systems from 4 to 10 kW £1,662 per kW, both a little below the year before.
Scotland was one of the cheaper parts of Great Britain for small systems that year: London and the South West averaged £2,177 per kW, and the North West of England £2,021. One date is worth knowing: the 0% VAT rate on installed solar ends on 31 March 2027, and from 1 April 2027 a £8,000 job would carry £400 of VAT, by our arithmetic.
| Size | Scotland average | About |
|---|---|---|
| 3 kW | £1,944/kW | £5,850 |
| 4 kW | £1,944/kW | £7,800 |
| 5 kW | £1,662/kW | £8,300 |
Scotland's 2022 Census counted 2,509,300 households. 32.4% lived in a tenement or purpose-built flat, 23.9% in a detached house, 23.3% in a semi and 18.2% in a terrace (Scotland's Census 2022). 63.2% owned their home.
23%
The Scottish House Condition Survey puts tenements at 23% of homes, and 7% are pre-1919 tenements (SHCS 2024). Under the Tenements (Scotland) Act the top flat usually owns the roof over it, but every owner shares its upkeep.
Solar on tenements and flats23.9%
Far more common than in English cities. A detached house has its own roof and no neighbours to agree with, and often room for a battery, which our battery guide covers.
What your roof would make17%
Stone walls and slate roofs need a check before panels go up, and a roof that needs strengthening can need a building warrant.
Stone-built and older homes8%
About 198,000 Scottish homes had solar panels for electricity, hot water or both in 2024 (SHCS 2024).
All guidesScotland has its own permitted-development order. Class 6HA, added from 24 May 2024, lets you fit solar to a house, a building with flats or a single flat without a planning application, provided the panels protrude no more than 1 metre from the outer surface of the wall, roof plane, ridge or chimney (legislation.gov.uk). It does not apply to listed buildings or World Heritage Sites, and in a conservation area panels cannot go on the principal elevation or on a side elevation that fronts a road.
Building standards are separate. West Lothian Council, for example, says roof panels on a one or two-storey house need no building warrant if the roof can take the weight, but strengthening the roof does need one (West Lothian Council). Check with your own council.
Who looks after the wires depends on where you live: SP Energy Networks in central and southern Scotland, and SSEN in the north (SSEN). Under G98 a system up to 3.68 kW on a single-phase supply is connected first and notified after; bigger systems apply first under G99.
Not on the east coast. Dundee's 945 kWh per kW and Edinburgh's 908 both beat central Manchester's 888 on the same PVGIS settings. The west and the islands are lower: Glasgow 855, Lerwick 765, Fort William 675. Long summer days make up for some of the dark winters, as the chart shows.
| Station | Sunshine (hours) | Rain (mm) | Rain days |
|---|---|---|---|
| Edinburgh (Royal Botanic Garden) | 1,449 | 728 | 128 |
| Glasgow (Bishopton) | 1,344 | 1,370 | 181 |
| Aberdeen (Dyce) | 1,447 | 833 | 143 |
| Inverness | 1,250 | 755 | 148 |
| Lerwick | 1,158 | 1,252 | 204 |

This guide installs nothing and recommends no firm. The protections are the same across Scotland: an installer certified by MCS, membership of a consumer code such as RECC or HIES, a written, itemised quote, and protection for any deposit.
They can be, because output depends on daylight more than warmth. PVGIS puts a well-angled roof at about 945 kWh a year per kW in Dundee and 908 in Edinburgh, more than central Manchester. Glasgow is lower at 855 and the wet west Highlands lowest. Whether it suits you depends on your roof and when you use power.
Not for households that can pay. Home Energy Scotland stopped funding solar PV and batteries for applicants sent a link after 6 June 2024. Lower-income households may get solar through Warmer Homes Scotland or a council Area Based Scheme if they meet those schemes' rules.
Usually not. Since 24 May 2024, Class 6HA lets you fit panels to a house or flat without an application if they stand no more than 1 metre proud of the roof or wall, unless the building is listed or in a World Heritage Site. In a conservation area they cannot go on the principal elevation or a side facing a road.
Under the Tenements (Scotland) Act 2004, unless the title deeds say otherwise, the top flat owns the roof over it, but under the Tenement Management Scheme the roof is scheme property that all owners maintain. Talk to the other owners before planning panels.
No. GOV.UK states the Boiler Upgrade Scheme is open to people in England and Wales. In Scotland, Home Energy Scotland runs a separate grant and loan for heat pumps, which no longer covers solar PV.
SP Energy Networks in central and southern Scotland and SSEN in the north. A typical home system up to 3.68 kW on a single-phase supply is connected by the installer and then notified (G98); larger systems need agreement first (G99).
