Solar for Schools and Public Sector: What We've Learned Delivering These Projects

Public sector solar projects (schools and academy trusts, councils, further and higher education) carry constraints that a standard commercial rooftop project doesn’t. A few patterns we’ve seen consistently across our education and local authority projects.

Budget cycles and business case scrutiny shape timelines more than the technical design does

Public sector capital spending typically runs against a financial year, with business cases needing to clear internal sign-off before works can start. Building enough lead time into a project schedule for this (rather than assuming a private-sector-style turnaround) avoids the single most common cause of delay we see on these projects.

Funding routes for solar panels for schools

Funding is usually the first question a school asks, and there are now three main routes.

Great British Energy Solar Partnership

The government and Great British Energy are funding rooftop solar for around 350 state schools and colleges, prioritising more deprived areas. The Department for Education selects and coordinates the schools directly, so there is no open application.

Power purchase agreement pilot

DfE is also piloting a model for around 150 more schools and colleges in Yorkshire and the Humber, the East Midlands and the South East. A private-sector partner pays for the installation and upkeep, so there is no upfront cost to the school. Procurement is due to begin in autumn 2026, and DfE aims for all schools and colleges to be able to buy renewable energy this way from 2027 to 2028. The pilot details are on GOV.UK.

Your own budget or finance

For schools and academy trusts outside these programmes, the system can be paid for from capital budgets. We can introduce you to our finance partners and point you to any local grants available for your area.

Educational and community value adds to the case, not just the energy savings

At Grange Primary School, module-level monitoring via 104 SolarEdge power optimisers was specified partly so pupils and staff could engage with real-time generation data as a teaching resource, supporting the council’s wider climate action programme, alongside the direct £26,500 annual energy saving. That combination of hard financial return and visible sustainability and educational value is often what secures sign-off internally, not the payback figure alone.

We can also help with the educational side, sharing how the system works and what it generates with pupils and staff.

Minimising disruption to term-time operations

All of our staff working on school sites are enhanced DBS checked, and wherever possible we schedule school works to start and finish within the school holidays, so staff and pupils see as little disruption as possible.

More widely, school and campus projects need to work around term dates, exam periods and, for larger estates work like our University of Westminster project, summer closure windows, coordinated closely with site security and estates staff. Phased delivery plans that respect the institution’s calendar, not just the contractor’s, make these projects run smoothly.

Scale varies enormously, and the fundamentals still apply

Our education and public sector portfolio spans a 48.6kWp single primary school installation (Cauldwell Primary School) through to 4.1MW across a national research campus (Harwell, for STFC and UKRI), with schools like Bedford Academy (108kWp) in between: very different scales, but the same underlying discipline: accurate site-specific irradiance modelling, a structural survey before design, and early engagement with the DNO where system size warrants it.
