Solar Panels in Northern Ireland
Northern Ireland has a single distribution network operator, NIE Networks, covering all six counties. Solar yield is broadly similar to west Scotland — lower than mainland GB, but the Northern Ireland Renewable Heat/microgeneration support schemes and rising electricity prices still make the case for solar in most homes.
Solar generation in Northern Ireland
Averaged across Northern Ireland's 6 counties, a 4 kWp south-facing system generates around 3,184 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £780 of electricity you would otherwise buy from the grid — though Down runs ahead of that average, at 805 kWh per installed kWp per year.
A typical 4 kWp system with a 5 kWh battery costs £7,000–£11,000 installed. At current energy prices, most homeowners in Northern Ireland break even within 11–13 years, and Smart Export Guarantee (SEG) payments on surplus exported energy reduce that further.
About Northern Ireland
Belfast's dense urban terraces, the Mourne Mountains and the Sperrins' rural uplands all sit under a single distribution licence — NIE Networks is the only network operator in Northern Ireland, unlike Great Britain's multiple regional DNOs. Solar yield here runs broadly in line with western Scotland, lower than most of mainland Great Britain, but rising electricity prices and local microgeneration support still make the case for solar in most Northern Ireland homes.
