Solar panels for academies and multi-academy trusts
A trust-wide solar programme needs more than a list of large roofs. It needs comparable site data, a defensible prioritisation method, clear governance and contracts that work across the estate.

Key takeaways
- Screen the whole estate before choosing sites, then phase delivery around roof condition, demand, grid capacity and budget.
- Use one set of assumptions and one minimum technical specification so bids can be compared fairly.
- Resolve tenure, roof warranties, asbestos, planned condition work and insurer requirements before detailed design.
- Put procurement thresholds, delegated authorities, conflicts and trustee reporting into the programme plan.
- Measure actual generation and savings at site and trust level after handover.
A practical portfolio process
1. Create the estate baseline
List every site, MPAN, annual consumption, half-hourly profile, tariff, roof area, roof age, tenure, condition works and planned changes such as heat pumps or EV charging.
2. Rank sites consistently
Score structural readiness, daytime demand, self-consumption, grid position, planning risk, access, expected occupation and delivery complexity. Keep excluded sites visible with reasons.
3. Survey the shortlist
Confirm structure, coverings, shading, cable routes, switchgear, fire strategy, asbestos information, safe access and Distribution Network Operator requirements.
4. Approve delivery waves
Group sites into manageable phases, with a clear business case and risk allowance for each. Use lessons from the first wave to improve later designs and mobilisation.
Capital purchase or PPA?
Capital purchase retains ownership and the full value of generated electricity, but competes with other estate needs. A PPA can avoid upfront purchase cost, but the trust commits to a long-term electricity and property arrangement.
Capital comparison
Show total installed cost, VAT treatment, maintenance, inverter replacement assumptions, degradation, export, avoided electricity cost and downside sensitivities.
PPA comparison
Test starting tariff, annual indexation, minimum purchase commitments, term, performance guarantees, roof access, change of use, termination, assignment and end-of-term options.
Governance and procurement
The Academy Trust Handbook requires trusts to manage resources properly and demonstrate regularity, propriety and value for money. Apply the current handbook, procurement rules and your own scheme of delegation.
Decision record
Keep the needs assessment, options appraisal, tender documents, evaluation, conflicts register, approvals and legal advice together for audit and trustee scrutiny.
Technical consistency
Set minimum requirements for modules, inverters, monitoring, fire safety, warranties, workmanship, roof interfaces, commissioning data and handover documents.
Stakeholder approvals
Map the trust board, finance committee, estates team, school leaders, local authority or diocese, landlord, lender, insurer and Distribution Network Operator.
Performance reporting
Report generation, availability, self-consumption, export, avoided cost and faults against the approved model. Do not rely only on installer portal screenshots.
Data pack for every academy
Request 12 months of full bills and half-hourly consumption for each MPAN, plus roof drawings, condition reports, site plans, asbestos register, electrical single-line information and details of planned estate changes.
A single spreadsheet with one row per site makes portfolio screening faster and reduces repeated questions to school teams.

Frequently asked questions
Should a MAT procure solar one school at a time?
Not automatically. A trust-wide screening exercise can create consistent data, specifications and commercial comparisons. Delivery can still be phased so urgent roof work, grid constraints and budgets are respected.
Which academy sites should go first?
Prioritise sites with sound roofs, strong daytime electricity demand, stable long-term occupation, usable grid capacity and few planning or access complications. High bills alone do not prove that a site is the best first project.
Can an academy trust use a solar PPA?
Potentially, subject to procurement, legal, accounting, estates and value-for-money review. The trust should test tariff indexation, contract term, roof rights, break clauses, maintenance duties and end-of-term ownership.
Does each academy need its own grid application?
Usually each separately connected site needs the appropriate application or notification to its Distribution Network Operator. Portfolio procurement can coordinate this work, but capacity and conditions remain site-specific.
What should trustees receive before approval?
A clear options appraisal, site-ranking method, whole-life financial model, procurement route, risk register, roof and electrical findings, proposed contracts, delivery plan and method for reporting actual performance.
