Solar panel grants for schools

UK schools are the most heavily-grant-supported solar PV sector. The Public Sector Decarbonisation Scheme provides 100% capital grants for state-maintained schools and many academies. The Salix Recycling Fund provides 0% interest loans repaid from energy savings. Together they can fund commercial solar installations of 15-200 kWp per school site with no net cashflow impact on the school budget. The challenge is access: PSDS funding rounds are heavily oversubscribed within hours of opening, and academy eligibility varies by trust type.

Typical buyer	School Business Manager / Bursar / MAT CFO
Typical system size	15 kWp – 200 kWp typical per school

Why schools are buying solar in 2026

100% grant routes available

PSDS funds the full capex of qualifying projects. No school capital required.

Wider net zero commitments

UK Department for Education committed to net zero by 2050; many local authorities have earlier targets (2030-2038).

Curriculum value

Solar PV with live monitoring supports KS2 and KS3 science curriculum — common motivator for governing body support.

Holiday period export

School summer holiday + Easter + Christmas / February half-term = 13-15 weeks of high-export periods. SEG revenue covers significant fraction of operating costs.

MAT-level standardisation

Multi-academy trusts increasingly standardise solar specifications across their estate — driving procurement scale and consistent technical performance.

Sub-sector breakdown

Different parts of this sector have different load profiles, building types and grant eligibility.

State-maintained primary schools — Typical system 15-30 kWp. PSDS + Salix funding stack.
State-maintained secondary schools — Typical system 50-150 kWp. PSDS funding strong.
Multi-academy trusts (MATs) — Programme rollouts across 5-50 schools. Eligibility varies — check current Salix guidance.
Sixth-form colleges and FE — Typically 100-300 kWp. Capital programmes through ESFA + PSDS.
Independent / private schools — PSDS not eligible. AIA + SEG + charitable trust funding routes.
Special educational needs (SEN) schools — Often higher per-pupil capital allocation; LA-led.
Boarding schools (state) — 24/7 occupancy — higher self-consumption than day schools.
Free schools and academies — Variable PSDS eligibility — confirm with Salix.

Sector case study

Case study — Multi-academy trust of 22 primary schools, North East England, 2024-2025 rollout.

The trust operates 22 primary schools across Durham, Tyne & Wear and Northumberland. Average school: 350 pupils, 1,500 m² floor area, 110,000 kWh/year electricity. The trust applied for PSDS Phase 3b funding in 2023, securing £3.6m for an estate-wide decarbonisation programme. Solar PV was the largest single technology — averaging 28 kWp per school, total 615 kWp across the estate.

Capex: £2.2m for solar (excluded from PSDS competitive scoring on its own; included as part of integrated heat pump + insulation package). PSDS grant covered 100% of qualifying capex. Annual electricity import reduction across the estate: 540,000 kWh; SEG income (school holiday periods drive material export): £21,000/year combined. Annual carbon saving: 113 tCO2e. The trust now reports against its net-zero-by-2035 pledge with credible Scope 2 evidence.

Sector-specific watch-outs

PSDS is wildly oversubscribed. Phase 3a (Oct 2021) closed within 72 hours; subsequent phases within 24-48 hours. Be RIBA Stage 3 ready before the next window opens.
Academy eligibility varies. Some academy types are PSDS-eligible (LA-maintained transitioning); others (free schools, voluntary aided, foundation schools) have different rules. Check the current Salix academy eligibility list.
Solar-only applications underscore. PSDS prioritises heat decarbonisation. Standalone solar applications struggle — include heat pump + insulation + BMS in the package.
Procurement constraints. Public sector procurement rules (PCR 2015 / Procurement Act 2023) require tendered procurement above £213k. Build 8-12 weeks into the programme timeline.
Carbon factor changes. Grid carbon factor falls year-on-year. A project that delivered 80 tCO2e/year in 2020 saves only ~60 tCO2e/year in 2026 — strengthen the case with locked-in factors where possible.

FAQs

Solar panel grants for schools · FAQs

Can my school get 100% grant funding for solar?

Yes — through the PSDS, state-maintained schools and many academies can secure 100% capital grant for solar PV (typically as part of a broader heat decarbonisation package). The challenge is timing: PSDS funding rounds open infrequently and close fast.

What is the typical solar system size for a UK primary school?

Typical primary school rooftop solar is 15-30 kWp — depending on roof area, pitch, shading and electrical service capacity. Average annual generation 14,000-28,000 kWh, saving £3,500-£7,000/year on electricity bills.

How does Salix Recycling Fund work for schools?

Salix lends at 0% interest, with the loan repaid from the energy savings the project delivers. Typical repayment over 5-8 years. The school pays slightly more than its energy savings during the loan period, then keeps 100% of savings after the loan repays. Full Salix guide.

Can private schools get PSDS funding?

No — PSDS is for public sector bodies only. Independent schools should use the AIA / Full Expensing route + SEG + (if registered charity) charitable trust funding routes.

Does solar affect school admissions or league tables?

No direct effect. But many parents and school governance bodies now consider environmental credentials in selection — particularly at secondary level. Solar can also support the Eco-Schools Green Flag award.
