Factory Solar by Location
Solar irradiance varies across the UK — from Cornwall averaging 1,200 kWh/m²/year to Scotland averaging 900 kWh/m²/year. Our location-specific guides cover local DNO requirements, planning policies, regional grant availability, and the best-performing factory installations in each area.
We have dedicated installation guides for over 100 UK locations including all major manufacturing hubs: the West Midlands automotive corridor, Manchester's chemical industry, Yorkshire's food manufacturing belt, and the South East logistics clusters. Each guide includes local case studies, DNO connection guidance, and planning considerations specific to that area.
