How much a solar roof makes in Lisburn
The European Commission’s PVGIS model gives 921 kWh a year for each kWp of panels in the centre of Lisburn, on an unshaded roof facing south at 35°. For a typical 4 kWp home system that is:
- a year
- 3,684 kWh
- in June
- 460 kWh
- in December
- 104 kWh
Other directions, pitches and shading change the figure, so the survey models your own roof. PVGIS (PVGIS-SARAH3 data, 14% system losses), checked November 2026.
What matters in Lisburn
- Roofs and wiringA generous roof area makes 6–10 kWp systems common here. Anything above 3.68 kW per phase needs a G99 application to NIE Networks before connection, so we allow for the extra lead time when we set the programme.
- Getting to youLisburn is reached from Larne by the A8, M2 and M1. We run surveys, installs and aftercare visits from our Larne base.
Planning and permissions
Lisburn city centre and Hillsborough village (BT26, in the same council area) are conservation areas, and the district has a good number of listed country houses. Lisburn & Castlereagh City Council handles applications. Ordinary suburban roofs outside those areas are usually permitted development.
Lisburn questions
Do I need G99 approval for a large Lisburn roof?
If you fit more than 3.68 kW per phase, yes. A 6 kWp array on a single-phase house is over that line, so it needs NIE Networks approval before we connect it, and approval can add weeks. We submit the application for you and give you a realistic switch-on date once the survey is done.
Should I cover the whole roof on a big detached house?
Not necessarily. Northern Ireland has no Smart Export Guarantee, and voluntary export tariffs are modest, so the value is in what you use yourself. We size the system to your consumption and any future heat pump or car, then tell you honestly if extra panels would barely pay back. The export guide has the tariff detail.
Does Hillsborough count as a conservation area for solar?
Hillsborough village centre is a conservation area. There, panels on a roof slope that faces and can be seen from a road need planning permission; a rear or side slope out of view is usually permitted development. Listed buildings need listed building consent first. Houses on the modern estates around the village are normally outside it, but check your address with Lisburn & Castlereagh City Council.
