Solar PPAs for Primary Schools

Solar fits primary schools perfectly

Primary schools have specific characteristics that often make solar PV especially well-suited: predictable daytime electricity consumption (mostly classroom lighting, IT, and catering), generally simple single-storey roof structures, and strong appetite for curriculum integration. Even modest installations deliver meaningful cost savings and powerful teaching opportunities.

Typical primary school installation

A typical UK primary school with 200-400 pupils consumes around 50,000-120,000 kWh of electricity per year. A 30-80 kWp solar PV system can offset 40-70% of that consumption, depending on roof orientation and daytime usage patterns.

System size: 30-80 kWp (around 75-200 panels)
Roof requirement: typically 200-500 m² of suitable roof
Annual generation: 27,000-72,000 kWh
Annual saving: £3,000-£9,000 depending on grid tariff
Installation time: 5-10 days, scheduled with your facilities team to minimise classroom disruption

Curriculum gold for KS1 and KS2

Primary children love the visibility of solar. Watching the sun create electricity in front of them, tracking daily generation, and understanding the link between weather and energy creates genuine engagement with science and sustainability from an early age. We provide free KS1 and KS2 lesson plans aligned to the National Curriculum.

What about low-occupancy periods?

Primary schools naturally have low electricity consumption during school holidays, when solar generation is often highest. Modern PPAs account for this through "self-consumption optimisation" and, where appropriate, battery storage to shift solar generation into school days. For most primaries, this does not materially affect the PPA economics, the 30-40 school weeks per year still deliver the bulk of savings.

Funding and governance

Maintained primary schools work through their local authority and governing body. Primary academies use their normal trust governance. The PPA route requires no capital outlay, no CIF bid, no PSL approval. The funder pays for everything; the school just buys the electricity at a fixed rate lower than grid.

Practical questions for primaries

Roof age: we survey before installation. If your roof is over 15 years old, we may sequence replacement first.
Installation noise: rooftop work is generally quiet (no piling or heavy plant). Coordinated with your school office to minimise classroom disruption.
Aesthetics: flush-mounted, neutral-coloured panels. From ground level, panels are barely visible on most rooftops.
Insurance: all liability and asset insurance handled by the funder. No impact on your existing buildings insurance.
Parent engagement: visible solar PV plus a foyer display showing live generation is a powerful signal of school values.

Small primary (60-150 pupils)

20-40 kWp typical. Modest savings, strong educational value, easy install.

Larger primary (200-400 pupils)

50-80 kWp typical. Material energy bill reduction, curriculum-rich, ready for end-of-term sustainability reporting.
