Why Schools Are Switching to Solar in 2025
Date: July 17, 2025 | Category: Blog, News
With soaring energy prices and growing pressure to meet climate targets, public sector institutions like schools, colleges, and academies are looking for smarter, cleaner ways to power their buildings. One solution is shining brighter than ever – solar energy.
Installing solar panels on educational buildings isn’t just about going green. It’s about cutting costs, improving energy independence, and setting an example for future generations. In this article, we explore why schools are increasingly turning to solar PV systems, the long-term financial and environmental benefits, and how Arc Renewables is helping the public sector meet its net zero ambitions.
Why Solar Makes Sense for Schools
Schools operate during daylight hours – precisely when solar panels generate the most electricity. This means they can use a high proportion of the energy they produce, reducing reliance on the National Grid and lowering bills immediately. On top of that, solar installations can help institutions:
- Offset rising electricity costs
- Meet environmental and net zero commitments
- Access funding and grants (such as PSDS and SALIX)
- Educate students on sustainability with visible, real-world tech
How Much Can Schools Save?
Below is a typical example comparing energy costs with and without solar, based on a medium-sized secondary school:
| Scenario | Annual Energy Bill | Estimated Solar Generation | Projected Savings |
|---|---|---|---|
| Without Solar | £45,000 | 0 kWh | £0 |
| With Solar (40kWp system) | £20,000 | 35,000 kWh | £25,000 saved per year |
Please note. These are estimates only. Contact a consultant to learn more.
These savings often mean schools recover their upfront investment in just 4–7 years – and with systems lasting 25+ years, most of that is long-term gain.
Supporting the UK’s Net Zero Mission
The UK Government’s Net Zero by 2050 target puts the public sector at the forefront of the green transition. Schools that invest in renewables now are not only cutting emissions – they’re securing energy resilience in an increasingly volatile market.
By working with Arc Renewables, schools gain access to trusted solar expertise, full project delivery, and asset management tailored to the education sector.

Empowering the Next Generation
Beyond the finances and carbon savings, installing solar panels sends a clear message to students: sustainability matters. Schools that take action show leadership and provide real-life educational opportunities, especially when paired with smart metering dashboards or live displays in common areas.

FAQs: Solar for Schools
Can schools access funding for solar panels?
Yes, schools may be eligible for grants such as the Public Sector Decarbonisation Scheme (PSDS) or SALIX Finance support. Arc Renewables can assist with applications.
Do solar panels disrupt daily school operations?
Not at all. Most installations are completed during school holidays or weekends to avoid disruption.
Are solar panels safe for school buildings?
Absolutely. All systems are designed to meet UK health, safety, and structural standards, with proper certification and fire safety compliance.
How long do solar panels last?
Most commercial solar PV systems are designed to last 25–30 years, with minimal performance degradation over time.
Can solar systems be integrated with batteries?
Yes. Battery storage is ideal for schools, allowing them to store excess energy for use later in the day or during peak hours.
