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. The payback depends on how much of the output the site uses during the day, so we model it from your own data, and under the 100% Annual Investment Allowance a company can deduct the cost from its taxable profit in year one.
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.
