A south-facing roof in Glasgow generates about 850 kWh per kWp a year on the EU's PVGIS model, below the south of England but still enough for solar to pay back, and every unit you use saves 26.11p at the Southern Scotland price cap rate. A typical 4.5kWp system would make about 3,825 kWh a year.

A south-facing 1kWp system at 35 degrees in Glasgow city centre generates about 850 kWh a year, according to the EU's PVGIS model. That ranks 20 of the 20 areas we cover, which run from 850 kWh in Glasgow to 1,119 kWh in Dorset. East and west roofs still work, at roughly a fifth less.
| Roof direction (35° pitch) | Per kWp a year | June | December |
|---|---|---|---|
| South-facing | 850 kWh | 110 kWh | 19 kWh |
| East-facing | 673 kWh | 101 kWh | 7 kWh |
| West-facing | 685 kWh | 104 kWh | 7 kWh |
PVGIS is a modelled figure for an unshaded roof with 14% system losses, and it runs higher than the MCS method installers must use for your written estimate, which gives roughly 800 to 950 kWh per kWp for a well-oriented UK roof. Use PVGIS to compare places and the installer's MCS estimate to plan your budget. Our guides to which direction panels should face and how much electricity solar panels produce go further.
What that electricity is worth in Glasgow
Every unit you use yourself saves 26.11p, the Ofgem price cap rate for direct debit customers in the Southern Scotland region from 1 October to 31 December 2026. The Great Britain average is 26.32p. Every unit you export earns whatever your Smart Export Guarantee tariff pays, which the Energy Saving Trust puts at around 12p typically.
Take the Energy Saving Trust's typical 4.5kWp home system. On the PVGIS figure for Glasgow it would generate about 3,825 kWh a year. If you used all of it, that would be worth about £999. If you exported all of it, about £459. Real homes sit between the two, and a battery or daytime use pushes you towards the higher figure. The Energy Saving Trust prices that typical system at around £7,600. See our solar panel cost guide and current export rates.
Less sun, but long summer days
Glasgow's yearly output is about a sixth below London's, and the gap is widest in winter. On the PVGIS model a south-facing kWp makes about 110 kWh in June in Glasgow against about 123 in London, but only about 19 kWh in December against about 37. Plan your budget on the summer half of the year and treat winter output as a bonus.
Ask installers for a month-by-month generation estimate, not just an annual figure. The Energy Saving Trust's payback estimates for Scotland are longer than for southern England: about 11 to 12 years in Stirling against about 9 in London.
Flats and tenements in Glasgow
More than two-thirds of Glasgow adults (68.6%) live in flats, against 32.4% across Scotland, according to the Scottish Household Survey 2024 figures Glasgow publishes. Only 41.6% are owner-occupiers, against 63.1% nationally. That is why Glasgow has fewer solar installations per household than Edinburgh or Manchester: about 36 per 1,000 households at the end of 2025 by our count from government data, against about 69 across the UK.
Scotland's planning rules are more helpful to flats than England's. The Scottish Government's householder guidance says solar panels on a flat or on a building containing flats are permitted development, as long as no part sticks out more than 1m. Planning is not the obstacle in a tenement; the shared roof is. You will need the agreement of the other owners under your title deeds, so start that conversation before you ask for quotes. See our guide to solar panels for flats for tenement ownership rules.
Planning in Glasgow: conservation areas and listed buildings
In Scotland, rooftop solar on a home is permitted development, except on a listed building, in a World Heritage Site, or in a conservation area on the principal elevation or a side elevation facing a road. Glasgow has 25 conservation areas, including Glasgow West, Glasgow Central, Park, Dennistoun, Strathbungo and the Pollokshields areas, and the council has an online map to check your address.
Glasgow's historic environment guidance adds that panels on listed buildings, or on unlisted buildings in conservation areas, should not be visible from public view at street level or fixed to the front elevation. A rear roof slope is usually the route. Our guide to permitted development for solar panels compares the four nations.
Funding in Glasgow: what Home Energy Scotland does and does not cover
The Home Energy Scotland Grant and Loan does not fund standalone solar panels. The only solar electricity measure it lists is hybrid solar PV-T, which generates electricity and heats water, and that gets an interest-free loan of up to £5,000 with no grant. Heat pumps get up to £7,500 in grant plus an optional £7,500 interest-free loan. Warmer Homes Scotland, for households on qualifying benefits, lists home renewables among possible improvements without naming solar panels.
Our guide to solar panel grants in the UK covers the rest of the picture.
Your network operator in Glasgow
Glasgow's network is run by SP Energy Networks, which covers central and southern Scotland. For a typical home system up to 3.68kW, SP Energy Networks must be told no later than commissioning, and the G98 form must reach it within 30 days. Larger systems fall under G99 and need approval before connection. See our G98 and G99 guide, and compare with solar panels in Edinburgh or solar panels in Manchester.
Getting solar quotes in Glasgow
Get at least three written quotes from MCS-certified installers, each with a performance estimate for your roof and a full breakdown of what is supplied. That is the Renewable Energy Consumer Code's advice. Never pay more than 25% up front, and walk away from anyone offering a discount to sign on the day. Our guide to choosing a solar installer covers what to check.

Are solar panels worth it in Glasgow?
For a house or a block whose owners agree, usually yes, but payback takes longer than in the south. Glasgow generates about 850 kWh per kWp a year on the PVGIS model, and every unit you use saves 26.11p at the Southern Scotland price cap rate for October to December 2026. The Energy Saving Trust estimates about 11 to 12 years for Stirling.
Can I put solar panels on a tenement flat in Glasgow?
Planning usually is not the problem: Scottish guidance treats solar on a flat or a building of flats as permitted development if no part sticks out more than 1m. The shared roof is, because you need the other owners' agreement under your title deeds. Conservation areas and listed buildings have extra limits.
Is there a grant for solar panels in Glasgow?
Not through Home Energy Scotland for standard solar panels. Its Grant and Loan funds hybrid solar PV-T only, with an interest-free loan of up to £5,000 and no grant. Warmer Homes Scotland, for households on qualifying benefits, lists home renewables among possible improvements.
Do I need planning permission for solar panels in Glasgow?
Usually not. In Scotland rooftop solar on a home is permitted development, except on a listed building, in a World Heritage Site, or in a conservation area on the principal elevation or a road-facing side. Glasgow has 25 conservation areas and an online map to check.
Who is the network operator for solar in Glasgow?
SP Energy Networks. For a typical home system it must be told no later than commissioning, with the G98 form arriving within 30 days.
