Solar Panels in Gwent
We connect homeowners across Gwent with MCS-certified solar installers. South-east Wales along the M4 corridor, covering Newport and Monmouthshire, has denser urban housing near the Severn Estuary and more rural terrain toward the Brecon Beacons.
Solar generation in Gwent
According to PVGIS irradiance data for Wales, a typical 4 kWp south-facing system in Gwent generates around 3,840 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £941 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 Gwent. At current energy prices, most homeowners break even within 9–11 years.
Local grid: National Grid Electricity Distribution (South Wales)
Every solar install in Gwent connects to the grid through National Grid Electricity Distribution (South Wales), who require a G98 notification for systems up to 3.68 kW or G99 approval (up to 45 working days) for anything larger. Your MCS-certified installer takes care of whichever applies, included in the price.
About Gwent
Denser urban housing near the Severn Estuary contrasts with the more rural terrain toward the Brecon Beacons further north. Newport's transporter bridge and the ruined Tintern Abbey in the Wye Valley sit alongside the former steel town of Ebbw Vale.
