Solar & Your School Climate Action Plan
A climate action plan needs a measurable, headline carbon win — and on-site solar is usually the biggest one a school can make, now fundable at zero capital cost.
The plan needs a headline win — solar is it
A credible school climate action plan covers estates, curriculum, culture and community — but the part that gets measured, reported and noticed is the estates carbon line. On-site solar PV is usually the largest single reduction available to a school: it is big (a 50 kW system avoids roughly 9 tonnes of CO₂ a year), it is metered (so the claim is auditable, not estimated), and it is visible to pupils every day.
It also pays its own way: the carbon win and the budget win are the same project. A school that justifies solar on savings alone delivers its climate plan headline as a by-product.
And the barrier that used to stop climate plans — capital — has gone: grants exist for eligible schools, and the zero-capex PPA funds the same system without a pound of budget.
Estate measures a climate plan can count on
| Measure | Carbon impact | Capital needed |
|---|---|---|
| Solar PV | Largest single reduction; metered & auditable | £0 under PPA / grants |
| Battery storage | Raises solar self-consumption | £0 within PPA |
| EV charging / car ports | Transport decarbonisation + income | £0 within PPA |
| Low-E window coating | Heating carbon, overheating | Low / funded options |
| LED + controls | Fast electricity reduction | Low, quick payback |
Indicative — measure selection and sizing come from the whole-site assessment. See the capability statement.
An auditable number, not a slogan
The reason solar anchors a credible climate plan: the saving is calculated from data the school already has.
- Baseline: 12 months of half-hourly electricity data establishes current grid consumption and carbon
- Model: solar generation and self-consumption are simulated against the actual load profile
- Report: tonnes of CO₂ avoided per year, on current grid carbon factors — auditable and repeatable
- Track: monitoring feeds progress into the plan year after year, alongside cost savings
What the plan gains
- A headline number for governors, trusts and inspectors
- Evidence for carbon reporting (SECR where the trust qualifies)
- A living curriculum asset — live generation data in the classroom
- Credibility with pupils and parents: the plan is built, not written
From plan on paper to panels on the roof
UEC Energy's whole-site assessment produces exactly what a climate action plan needs: the baseline, the ranked measures with carbon and cost impacts, and the funding route for each — grant, Salix or the zero-capex PPA. It is the "Assess" step of the RECfA programme, delivered by an ESOS Lead Assessor.
Most schools start with the free review: 12 months of meter data in, a ranked carbon-and-savings plan out.

Climate plan questions, answered
What is a school climate action plan?
A structured strategy for reducing the school or trust's carbon footprint and embedding sustainability — estates, curriculum, culture and community. National policy direction, including the DfE's sustainability and climate change strategy, encourages every education setting to have one.
How does solar help?
It is usually the largest single, measurable carbon reduction a school estate can make — around 9 tonnes of CO₂ a year for a 50 kW system — and it is metered, so the claim is auditable rather than estimated.
We have no capital budget. Can we still act?
Yes — grants exist for eligible schools, and the zero-capex PPA delivers the same physical carbon reduction with no capital outlay: the school buys cheaper fixed-price on-site electricity while the funder owns the asset. See solar PPA for schools.
How is the carbon saving measured?
From half-hourly data: baseline grid consumption, model solar generation and self-consumption, apply current grid carbon factors. The output is an auditable tonnes-per-year figure that feeds carbon reporting and plan tracking.
