Solar Panels in West Glamorgan
We connect homeowners across West Glamorgan with MCS-certified solar installers. Swansea and the Gower Peninsula combine an urban bay-front city with an exposed, sunny coastline that gets more direct sun than the Valleys further inland.
Solar generation in West Glamorgan
Using PVGIS irradiance data for Wales, a 4 kWp south-facing array in West Glamorgan produces roughly 3,860 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £946 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 West Glamorgan. At current energy prices, most homeowners break even within 9–11 years.
Local grid: National Grid Electricity Distribution (South Wales)
Anywhere in West Glamorgan, the grid connection for a new system goes via National Grid Electricity Distribution (South Wales). 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.
