Cloud cover in the North West puts people off solar, and it should not. Panels run on daylight, not direct sun, and Manchester roofs generate perfectly respectable output.
Realistic generation
A south-facing 4 kW array in Greater Manchester generates roughly 3,200 to 3,600 kWh a year. East or west facing knocks that down by around 15%, which is often still worth doing because it spreads generation across morning and evening.
What you will pay
Costs track the national picture: around £6,000 to £8,500 for a 4 kW install. Terraced streets are sometimes a little cheaper because scaffolding is simpler, while three-storey Victorian properties in areas like Didsbury or Chorlton cost more to access.
Local considerations
- Conservation areas — parts of Manchester and Salford have restrictions; check before ordering.
- Roof condition — older slate roofs may need attention before mounting.
- Shading — dense terraces and mature trees make micro-inverters or optimisers worth quoting.
Choosing an installer
Insist on MCS certification (required for the Smart Export Guarantee), ask for local references, and confirm who handles the DNO notification and export tariff paperwork.
