Comparison

The five routes at a glance

The physical system is the same in every case — what differs is who pays, who owns it, and what happens to the savings.

Route	Cost to school	Who owns the panels	Savings profile	Guide
1. Great British Energy grant	£0 (grant-funded)	School	Full savings, from installation	GBE scheme guide →
2. Salix / PSDS	Grant covers eligible share	School	Full savings on funded share	Salix guide →
3. Condition Improvement Fund	Grant for eligible condition works	School	Best with roof + solar combined	Details →
4. Capital purchase	£20k–£200k+ upfront	School	Fastest full return; payback typically 4–8 yrs	Details →
5. Solar PPA	£0 — pay per kWh used	Funder (transfer option at yr 15)	Immediate saving vs grid; 15-yr fixed price	PPA guide →

Indicative cost bands and payback ranges are pre-survey guides — see our costs breakdown for detail. Actual figures are modelled per site.

Detail

Each route in one paragraph

1 · Great British Energy grant

The government's dedicated school solar programme: up to £255m partnership, 245 schools fitted, 100 more in the current £40m wave. Panels are school-owned and all savings stay in the budget. Waves are periodic — being evidence-ready matters more than queueing.

2 · Salix / PSDS

Salix Finance has delivered £1bn+ of public-sector decarbonisation funding across PSDS phases. Solar can be one measure within a wider efficiency project — the "efficiency first" logic means applications need consumption data, condition surveys and quantified savings.

3 · Condition Improvement Fund

For academies, sixth-form colleges and VA schools. CIF covers building condition works — most powerful when roof refurbishment and solar are scoped together, so one disruption window delivers both a sound roof and cheaper electricity.

See Costs & Sequencing

4 · Capital purchase

Outright ownership gives the fastest full return and simplest long-term economics — if reserves (or borrowing capacity) exist and the roof is sound. The school also carries maintenance, insurance and inverter replacement over the system life.

See Cost Bands

5 · Solar PPA (zero capital)

The funder pays, owns, insures and maintains the system; the school buys its own cheaper electricity at a fixed price for 15 years — not linked to inflation. Immediate savings, no budget impact, asset transfer option at year 15. This is the model the government is piloting with 150 schools — available independently now.

Bonus · Battery storage

Whichever route funds the panels, battery storage can usually ride along — funded within the same PPA structure or added to a grant project scope. It raises self-consumption and powers evening lettings.

Decision Guide

Which route fits your school?

Four questions answer most of it:

Is a GBE or Salix window open and are you eligible? → Take the grant. School ownership keeps every pound of saving. Register interest and build the evidence pack now so you're ready.

Do you have reserves and a roof in good condition? → Capital purchase gives the fastest full return. Model payback honestly against your tariff, including maintenance.

Is the roof due refurbishment? → Sequence it first (CIF may fund the roof), then solar — or let the PPA funder coordinate both timings with you.

None of the above, or you don't want to wait? → The solar PPA: zero capital, immediate savings, 15-year price certainty, no dependency on funding rounds.
