Solar Panels in Dyfed
We connect homeowners across Dyfed with MCS-certified solar installers. Rural west Wales — Carmarthenshire, Ceredigion and Pembrokeshire — with a mild, wet Atlantic coastal climate and mostly detached or semi-detached rural housing.
Solar generation in Dyfed
Based on PVGIS irradiance data for Wales, a 4 kWp south-facing system in Dyfed generates around 3,800 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £931 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 Dyfed. At current energy prices, most homeowners break even within 9–11 years.
Local grid: National Grid Electricity Distribution (South Wales)
Solar installations across Dyfed connect to the grid via National Grid Electricity Distribution (South Wales). Systems up to 3.68 kW require a G98 notification; larger systems need G99 approval, which can take 45 working days. Your MCS-certified installer handles both — it's included in the installation package, not an extra cost.
