Exeter industrial solar — the local picture
For UK industrial electricity at 27.69 p/kWh (Q1 2026 Ofgem), an Exeter factory drawing 800 MWh/year is paying ~£220,000/year for grid power. A 250 kW rooftop solar PV system on a typical factory roof will offset 35–55% of that, saving ~£58,000 in year 1 with full Annual Investment Allowance tax relief in year 1.

Exeter factory solar — expanded FAQ
How long does a Exeter factory solar install take?
From contract signature to commissioned system: 8–14 weeks for systems up to 500 kW, 12–16 weeks for 1 MW+. The longest item is the G99 grid connection (6–18 months DNO timeline) which your installer should initiate before contract. Physical install on roof: 2–5 days for 100–500 kW, 5–10 days for 1 MW+. Installers typically schedule the work around your shutdown windows.
What grants are available for Exeter manufacturers?
Nationally: the Industrial Energy Transformation Fund closed in July 2025 with no successor fund planned, so the Annual Investment Allowance (AIA) — 100% of capex up to £1m in year 1 — is the main relief. Locally, ask your local growth hub or combined authority about current regional business support.
Will I need planning permission in Exeter?
In England, rooftop solar PV on non-domestic buildings is usually permitted development (Part 14, Class J of the GPDO) up to 1 MW, subject to conditions; Scotland, Wales and Northern Ireland have their own rules. Listed buildings, conservation areas and PV projecting more than 200mm above the roof need full planning. Your installer should confirm planning status before quoting.
What roof types suit factory solar in Exeter?
All commercial roof types: standing seam metal (clamp-fix, no penetrations), profiled / corrugated metal (rail-mount), flat membrane (ballasted), single-ply EPDM (mechanically fixed). Asbestos-cement roofs cannot be retrofitted — refurbishment to a modern membrane is required first. See our roof weight load guide for structural requirements per roof type.
How do I get a quote for my Exeter site?
Three steps. (1) Submit a quote request with your annual electricity spend and roof type. (2) We pass your enquiry to a matched installer. (3) The installer can then model your half-hourly meter data and roof, survey the site and send a proposal. A quote request carries no obligation.
