Solar for Self-Storage in Scotland 2026
Self-storage solar — vast unused roofs + low operating load = export-heavy economics.
Quick answer
Self-storage in Scotland typically install 100-500kWp of commercial solar PV, with 5-7 year paybacks via CapEx. Capital allowances cover roughly 50% of cost in year-one tax relief.
Why self-storage in Scotland make ideal solar candidates
- Massive flat roofs (often 20,000+ sqft)
- Low on-site load = high SEG export revenue
- Single-tenant landlord = simple decision
- Three-phase usually present
- EV charging integration for customer-loading
Three funding routes
- CapEx — outright purchase. Best IRR. 50% first-year capital allowance on commercial.
- Lease — fixed monthly payments, no upfront cost.
- PPA (Power Purchase Agreement) — third-party owns the asset, you buy electricity at a fixed lower rate.
DNO process
Most commercial installs above 3.68 kW per phase (16 A — the G98 limit) require a G99 application to the local DNO. We submit, track and chase on your behalf — typical connection-offer timeline 6-12 weeks.
