Is My Belfast Roof Suitable for Solar?
Orientation, pitch, covering, condition and shading — the five things that decide whether your roof works.
Orientation
South is ideal. South-east and south-west are close behind. East and west work perfectly well, often with the array split across both. North-facing slopes are generally not worth it.

Pitch
Most UK pitches between roughly 20 and 50 degrees are fine. Very shallow pitches self-clean less well; very steep ones lose a little output but are otherwise workable.
Covering and condition
Tile and slate are standard. Flat roofs use frames. Metal uses clamps. What matters more than the material is condition — if the roof needs work, do it first.
Shading
Trees, chimneys, neighbouring buildings and, in some parts of Belfast, higher ground. Shading through the middle of the day matters far more than early morning or late evening shading.
The local picture
Northern Ireland has its own grid connection and export arrangements, so the process and the tariffs differ from Great Britain and your installer should confirm both.
