Solar Panels in Scotland
Scotland has the UK's lowest solar irradiance, rising notably from the Highlands and Islands in the north to the Central Belt and Borders in the south. SSEN Distribution covers the northern half of the country; SP Energy Networks covers the Central Belt and south.
Solar generation in Scotland
Averaged across Scotland's 13 counties, a 4 kWp south-facing system generates around 3,288 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £806 of electricity you would otherwise buy from the grid — though Dumfries and Galloway runs ahead of that average, at 855 kWh per installed kWp per year.
A typical 4 kWp system with a 5 kWh battery costs £7,000–£11,000 installed. At current energy prices, most homeowners in Scotland break even within 10–12 years, and Smart Export Guarantee (SEG) payments on surplus exported energy reduce that further.
About Scotland
Scotland's solar resource climbs steadily from the Highlands and Islands, where near-24-hour summer daylight partly offsets a low winter sun angle, down to the milder Central Belt around Glasgow and Edinburgh and the Gulf-Stream-warmed south-west coast around Ayrshire. SSEN Distribution covers the northern half of the country while SP Energy Networks (SP Distribution) runs the Central Belt and south — and Scotland's long tradition of hydro and wind generation means many homes already have grid-ready electrics for solar.
