Falkirk Solar Panels: The Complete 2026 Guide
Industrial heritage, modern grid, Polmont + Larbert + Grangemouth — Falkirk solar costs, paybacks + case studies.
Quick answer
Solar panels in Falkirk cost £6,500–£8,500 for a typical 4 kWp domestic install. Yields 890–900 kWh per kWp. Falkirk is one of Scotland's best commercial PV markets — strong SP Energy Networks DNO capacity, abundant industrial roof stock around Grangemouth + Larbert + Stenhousemuir. Domestic payback 7–9 years; commercial 5–7 years.
Falkirk's solar market split
Falkirk has two distinct solar markets:
Domestic: Polmont (FK2), Larbert (FK5), Camelon (FK1), Bo'ness (EH51) — modern suburban semi-detached + new-build estates. Standard 4–6 kWp installs, low planning complication.
Commercial: Grangemouth (FK3), Stenhousemuir (FK5), Bainsford (FK2), Larbert industrial — abundant flat-roof industrial units with strong DNO capacity (legacy of the industrial cluster).
Falkirk DNO — SP Energy Networks
All of Falkirk falls under SP Energy Networks. G98 same-day, G99 6–12 weeks for domestic. Commercial PV >100 kWp often gets approved faster than other parts of Scotland due to the industrial cluster's residual grid capacity.

Commercial PV in Falkirk — why this market is hot
Grangemouth's industrial decline left grid infrastructure that's now under-utilised. SP Energy Networks G99 applications for 100–500 kWp commercial systems are getting approved in 6–10 weeks vs the 10–16 weeks typical elsewhere in Scotland. The flat-roof industrial unit stock is enormous (Stenhousemuir, Bainsford, Grangemouth Estate, Larbert Industrial Estate).
We have delivered 6 commercial PV projects in Falkirk in 2025–2026, including a 350 kWp system at a Grangemouth chemicals supplier.
Finance routes
