Solar Panels in Dumfries and Galloway
We connect homeowners across Dumfries and Galloway with MCS-certified solar installers. This rural south-west corner of Scotland is the country's mildest region, bordering the Solway Firth, with mostly detached rural housing well suited to larger arrays.
Solar generation in Dumfries and Galloway
Using PVGIS irradiance data for Scotland, a 4 kWp south-facing array in Dumfries and Galloway produces roughly 3,420 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £838 of electricity you would otherwise buy from the grid.
On top of bill savings, surplus energy exported to the grid earns Smart Export Guarantee (SEG) payments — typically 4–6p/kWh with the main suppliers, or up to 15p/kWh with specialist tariffs like Octopus Outgoing.
A typical 4 kWp system with a 5 kWh battery costs £7,000–£11,000 installed across Dumfries and Galloway. At current energy prices, most homeowners break even within 10–12 years.
Local grid: SP Energy Networks (SP Distribution)
Anywhere in Dumfries and Galloway, the grid connection for a new system goes via SP Energy Networks (SP Distribution). Smaller systems (up to 3.68 kW) just need a G98 notification, while bigger ones need G99 approval — allow up to 45 working days for that. Either way, it's your MCS-certified installer's job, not an added fee.
