Scaffolding, roof access, lifting operations, cable routes, electrical shutdowns, deliveries and contractor compounds can affect school operations. Safeguarding, DBS expectations, pupil segregation, fire routes, exam periods and after-school activities should be planned before work starts."

Proposals should show design assumptions, expected generation, self-consumption, export income, payback, mounting method, roof warranty implications, DNO process, safety arrangements, monitoring and maintenance. Relevant commercial PV experience, insurance, accreditations and education-sector references should also be checked."

It may also be less attractive where the school has low daytime electricity use, limited grid connection capacity or uncertain long-term occupancy. A proper feasibility review should be completed before committing budget."
