Solar Panel Cost in Glasgow 2026

Quick answer

Solar panels in Glasgow cost £6,500–£8,500 for a typical 4kWp domestic install in 2026, generating around 3,520 kWh/year. Add a 5kWh battery and the total lands £10,500–£13,500. Glasgow yields are very slightly lower than Edinburgh due to higher average cloud cover — typical payback 7.5–10 years for solar-only.

Glasgow yield specifics

PVGIS modelling for Glasgow shows around 880 kWh per kWp installed annually for a south-facing 35° pitch — very close to the UK Central Belt average but ~3% below Edinburgh. East/west splits drop to 700–760 kWh/kWp.

For a 4kWp system: expect around 3,520 kWh/year.

Sandstone tenement roofs — the Glasgow specialist's challenge

Glasgow has more sandstone tenements than anywhere else in Scotland — particularly West End (G11, G12), Southside (G41, G42) and East End (G31, G32). Mounting solar on a sandstone-tenement roof needs:

• Slate-friendly hook systems — we use Schletter or K2 hooks specifically rated for slate
• Shared ownership consent — written consent from all owners of the close (we draft the consent form)
• Title deed check — some flat titles restrict roof modifications
• Scaffolding considerations — three-storey tenements need substantial scaffolding (£600–£1,000 of the quote)

Our typical tenement install: 4kWp on the rear of the roof, in-roof or low-profile on-roof mounting, EcoFlow PowerOcean inverter in the close meter cupboard.

New build estates — the smoother route

Glasgow's new-build estates (Robroyston G33, Maryhill G20, Easterhouse G34, Cambuslang G72) are typically solar-easy:

• Standard tile roofs, predictable structural ratings
• Newer consumer units, no upgrades needed
• Sometimes solar-ready conduit pre-installed
• Cleaner G98/G99 notifications

Expect quotes at the lower end of the £6,500–£8,500 range.

Detached suburban (Bearsden G61, Newton Mearns G77, Lenzie G66)

Typical detached/semi work. Larger systems possible (6–10kWp). Frequent battery+solar+EV charger combo. Standard install with no Glasgow-specific complications.
