Every DG postcode from Dumfries town to the Rhins of Galloway. Here's what to know about solar in each area.
Which DG postcodes do you cover?
We cover every postcode in Dumfries & Galloway — from Dumfries town (DG1) to Gretna (DG16). Dumfries & Galloway is Scotland's third-largest council area by landmass, with a large rural population. Many properties are off the mains gas network, relying on oil or LPG heating, which makes solar panels with battery storage particularly valuable for reducing energy costs.
Our MCS-certified installer partners are experienced with the full range of property types across the region — from town-centre terraces to remote Galloway farmhouses. Select your town below to learn about local considerations for solar installation.
Dumfries (DG1, DG2)
The largest town in the region with a mix of Victorian terraces, post-war semis, and modern estates. South-facing roofs are common in the older housing stock near the town centre. Being on the mains gas network, solar here is about reducing electricity bills rather than replacing heating. Roof access is generally straightforward with good road connections.
Solar panels in Dumfries →Annan (DG12)
A coastal town on the Solway Firth with a mix of traditional sandstone properties and newer developments. Salt-air considerations mean marine-grade mounting hardware is recommended for exposed coastal roofs. Good solar potential with relatively unobstructed horizons to the south.
Solar panels in Annan →Lockerbie (DG11)
A market town with a mix of detached properties and farms in the surrounding countryside. Many homes here are off mains gas, making solar paired with battery storage particularly effective for reducing grid dependency. Rural road access is generally good for installation vehicles.
Solar panels in Lockerbie →Castle Douglas (DG7)
A conservation town known for its Victorian architecture. Some properties in the conservation area may require planning permission for roof-mounted panels. Individual assessment is needed — where roof panels are restricted, ground-mounted options can be discussed. The town has good south-facing roof potential on properties outside the conservation zone.
Solar panels in Castle →Dalbeattie (DG5)
A small town nestled in a valley with a mix of granite-built properties and modern housing. The surrounding hills can affect shading at low sun angles in winter, but summer generation is strong. Battery storage is recommended here due to the number of off-mains-gas properties.
Solar panels in Dalbeattie →Kirkcudbright (DG6)
A historic harbour town with artists' colony heritage. Many properties are listed or within conservation areas, requiring careful planning for solar installation. Roof-integrated panels may be an option where conventional panels are not permitted. South-facing properties near the harbour have excellent solar potential.
Solar panels in Kirkcudbright →Newton Stewart (DG8)
The gateway to the Galloway Forest Park, with a mix of rural cottages and larger properties. Many homes here are off mains gas and rely on oil or LPG, making solar with battery a strong option for reducing energy costs. The surrounding Galloway Hills provide shelter from prevailing winds.
Solar panels in Newton →Stranraer (DG9)
A ferry terminal town on the Rhins of Galloway peninsula. Its exposed coastal location means corrosion-resistant mounting is essential. The peninsula position is not a barrier to solar — generation potential is comparable to inland D&G sites. Many properties here are off mains gas.
Solar panels in Stranraer →Moffat (DG10)
A Victorian spa town with handsome period properties. The surrounding hills provide a scenic backdrop but can create shading challenges for properties on north-facing slopes. Individual roof assessment is important here. Good road access for installation teams.
Solar panels in Moffat →Sanquhar (DG4)
A former mining town in upper Nithsdale with a mix of traditional housing and rural properties. Its inland position gives good solar irradiance with fewer coastal corrosion concerns. Many surrounding farms and cottages are off mains gas, making solar with battery storage worthwhile.
Solar panels in Sanquhar →Thornhill (DG3)
A small village in Nithsdale with a rural character. Properties here are typically detached or semi-detached with good roof space. The surrounding countryside means minimal light pollution and good solar access. Off-mains-gas properties are common in the surrounding area.
Solar panels in Thornhill →Gretna (DG16)
A border town near the English border with a mix of new housing developments and older properties. Good road connections make installation straightforward. Being close to the border, some properties may have different grid connection considerations — our installer partners check this during survey.
Solar panels in Gretna →Langholm (DG13)
A remote town in the Eskdale valley with a mix of traditional properties and surrounding farms. Its isolated position means many homes are off mains gas with high grid dependency — solar with battery can make a significant difference here. Access can be challenging in winter, so installation scheduling is important.

Many D&G properties are in remote locations with limited grid infrastructure. For these homes, solar with battery storage can significantly reduce reliance on the grid. Some properties may need a G99 application to SP Distribution (rather than the simpler G98 notification), which can add 11–30 working days to the timeline. Our installer partners handle all DNO paperwork as standard.
For coastal properties along the Solway Firth, marine-grade aluminium mounting and inverter enclosures are recommended to withstand salt-air exposure. This is a small cost increase but extends system life significantly in exposed locations.
FAQs
Do you cover every DG postcode in Dumfries & Galloway?
Yes. We cover every DG postcode from DG1 (Dumfries central) through to DG16 (Gretna), including all towns and rural areas in between. Our MCS-certified installer partners travel to remote properties across the entire region.
Do you install solar on coastal properties along the Solway Firth?
Yes. For exposed coastal properties in areas like Annan and Stranraer, our installer partners use marine-grade aluminium mounting hardware to withstand salt-air exposure. This extends system life in coastal locations and is specified as standard where needed.
Can you install solar on listed buildings or in conservation areas?
Listed buildings and some conservation area properties, particularly in Castle Douglas and Kirkcudbright, may require planning permission. Roof-integrated panels can be an option where conventional panels are not permitted. A surveyor assesses your property and advises on planning requirements.
What about remote off-gas properties in Galloway?
Many D&G properties are off the mains gas network and rely on oil or LPG. Solar with battery storage is particularly valuable for these homes, reducing grid dependency and energy costs. Some remote properties may need a G99 DNO application, which our installer partners handle.
