Solar Panels in Londonderry
We connect homeowners across Londonderry with MCS-certified solar installers. Northern Ireland's north-west, including Derry~/Londonderry city and the Sperrin Mountains, sees more Atlantic weather influence than the eastern counties.
Solar generation in Londonderry
Based on PVGIS irradiance data for Northern Ireland, a 4 kWp south-facing system in Londonderry generates around 3,160 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £774 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 Londonderry. At current energy prices, most homeowners break even within 11–13 years.
Local grid: NIE Networks
Solar installations across Londonderry connect to the grid via NIE Networks. 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.
