How much a solar roof makes in Larne
The European Commission’s PVGIS model gives 906 kWh a year for each kWp of panels in the centre of Larne, on an unshaded roof facing south at 35°. For a typical 4 kWp home system that is:
- a year
- 3,624 kWh
- in June
- 472 kWh
- in December
- 88 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 Larne
- Roofs and wiringA good spread of rural properties along the Antrim Coast on overhead rural feeders, which is the situation where a battery with backup capability earns its keep during winter storms. Seafront and hillside houses are exposed, so wind loading matters here as much as shading.
- Getting to youThere is no journey to speak of: surveys and installs start from our base in the town, and Larne customers are the shortest trip for aftercare visits.
Planning and permissions
Much of the coast north of Larne lies inside the Antrim Coast and Glens Area of Outstanding Natural Beauty. The permitted development rules for solar are the same inside an AONB: roof panels on a house, and one garden array of up to 14 m², are usually permitted development. A larger ground-mounted array needs planning permission, and in the AONB the council weighs its visual impact closely. Mid and East Antrim Borough Council decides.
Larne questions
Will a battery keep my Larne home running in a storm?
Only if it is fitted with a backup gateway. A standard grid-tied battery shuts down when the network drops. With the gateway, essential circuits such as lights, fridge, broadband and an oil boiler keep going. It is worth considering on the overhead rural lines around Glenarm, Carnlough and Islandmagee.
Can I build a ground-mounted array on land near the Antrim Coast?
One array of up to 14 m² and 2 m high in a house's garden is permitted development, AONB or not. Anything bigger, or an array out in a field, needs planning permission, and inside the Antrim Coast and Glens AONB the council weighs visual impact heavily. A roof array on an existing farm building or outbuilding is the more realistic route, and we can survey both options for you.
Do you cover Islandmagee, Glenarm and Carnlough?
Yes, they are the nearest rural jobs to our office at 5 Willowbank Road. Glenarm and Carnlough use BT44 postcodes rather than BT40, but both are a short run up the coast road. Tell us your address when you enquire and we will confirm the details.
