Regional Guides — Farm Solar Insights

UK farm solar economics vary materially by region. Annual irradiance ranges from 1,100 kWh/kWp in the South West and Anglesey down to 920 kWh/kWp in the Highlands and west Wales — a 16% spread that affects payback by roughly 6 months. DNO performance varies even more: UKPN delivers G99 in 6-10 weeks, while SSEN Highlands sometimes takes 12-20 weeks for the same project.

Grant availability is also regional. England farms access FETF (40% capital) and SFI (ongoing payments for agrivoltaic schemes). Wales uses the Welsh Farm Business Grant with quarterly windows and Farming Connect pre-application support. Scotland has CARES interest-free loans, the SRDP Sustainable Production Grant, and 50% capital support for islands and remote rural. Northern Ireland farms access the DAERA Farm Energy Efficiency Scheme at 40% capital.

Planning constraints differ too: AONBs and National Parks span the country differently (Cotswolds, Mendips, Lake District, Snowdonia, Cairngorms, Sperrins) and each affects ground-mount solar approvals. Conservation areas in market towns vary in strictness. Heritage buildings — particularly grain stores, oast houses and listed barns — are concentrated in certain regions.

This category covers the regional patterns that matter: South West and Wales (highest irradiance, NGED + SPEN DNOs), East Anglia (large arable holdings, UKPN, good grid capacity), Midlands (mixed farming, NGED, Cotswolds AONB), North and Yorkshire (livestock + arable, Northern Powergrid), Scotland (small farms + large estates, SSEN + SP Distribution), Northern Ireland (NIE Networks, DAERA grants).
