Solar Panels for Schools: Benefits, Costs, and Funding in the UK
Schools across the UK are under pressure to cut costs while also reducing their carbon footprint. With energy bills rising year after year, many schools are asking whether renewable energy could provide a long-term solution.
Solar panels for schools are proving to be one of the most effective answers. By generating clean electricity on-site, schools can slash utility bills, reduce reliance on the grid, and show pupils the value of sustainability in action.
This guide explores the benefits, costs, and funding opportunities for solar panels in UK schools—and why now is the perfect time to make the switch.

Why Solar Panels Make Sense for Schools
1. Significant Cost Savings
Schools are among the largest public sector energy consumers, with electricity demand often peaking during daylight hours. This makes them perfectly suited for solar power.
A solar PV system can reduce electricity bills by 30–50%, saving thousands of pounds each year. With budgets stretched thin, these savings can be redirected into teaching and learning.
2. Environmental Benefits
Installing solar panels helps schools:
-
Cut their carbon emissions by several tonnes each year.
-
Contribute to the UK’s Net Zero 2050 target.
-
Inspire students by showing sustainability in action.
3. Educational Value
Solar panels aren’t just an energy solution—they’re a learning opportunity. Schools can integrate real-time monitoring software into lessons, teaching pupils about renewable energy, climate change, and STEM subjects.
How Much Do Solar Panels for Schools Cost?
The cost of solar panels varies depending on system size and roof space. Schools typically require larger systems than homes, with installations ranging from 20kW to 100kW+.
-
A 20kW system (around 60–70 panels) may cost £25,000–£30,000.
-
A 50kW system (150+ panels) may cost £55,000–£65,000.
-
Larger systems can exceed £100,000.
While this sounds like a large upfront cost, the payback period is often just 6–10 years thanks to significant annual savings. Given that panels last 25 years or more, most schools enjoy 15+ years of free electricity.
Funding and Support for Schools
Schools don’t always need to fund solar panels themselves. There are several routes available:
1. Government Grants and Schemes
-
The Public Sector Decarbonisation Scheme (PSDS) has provided funding for energy efficiency and renewable projects in schools.
-
The Salix Finance scheme offers loans for schools to invest in energy-saving technology, repayable through future bill savings.
2. Community and Council Support
Some schools partner with local councils or community energy groups, allowing panels to be installed at little or no upfront cost in exchange for shared savings.
3. Power Purchase Agreements (PPAs)
Under a PPA, a solar provider installs panels on the school’s roof at no cost. The school then buys the electricity generated at a discounted rate compared to the grid. This ensures instant savings without capital expenditure.
Solar Panels and Battery Storage for Schools
Adding battery storage allows schools to:
-
Store surplus energy for use later in the day.
-
Reduce peak demand charges.
-
Increase savings and resilience.
Since schools typically operate during daylight hours, they benefit even without a battery, but storage can enhance performance and flexibility.
Case Study Example (Generalised)
A secondary school in southern England installed a 50kW solar PV system. The panels generate around 45,000 kWh per year, covering 40% of the school’s electricity demand.
-
Installation cost: £60,000
-
Annual savings: ~£8,000
-
Payback time: 7.5 years
-
CO₂ reduction: 12 tonnes per year
Beyond the financial savings, the system is used in science classes to demonstrate renewable energy in action, engaging students directly in sustainability.
Are Solar Panels Worth It for Schools?
Yes—when you consider the combined financial, environmental, and educational benefits, solar panels are one of the best investments a school can make.
-
Lower bills mean more money for staff, resources, and student support.
-
Reduced emissions support sustainability goals and set a positive example.
-
The technology provides an inspiring teaching tool for pupils.
With long lifespans, minimal maintenance, and multiple funding options, solar panels pay for themselves many times over during their lifetime.
The Installation Process
Installing solar panels on a school roof is straightforward:
- Site Survey: A professional installer assesses roof space, structure, and electricity usage.
- System Design & Funding Plan: A tailored proposal includes size, savings, and funding options.
- Installation: Panels are fitted during holidays or weekends to avoid disruption.
- Monitoring: Schools can track live energy production and savings online.
Solar panels for schools are more than just an energy-saving measure—they’re a way to secure financial stability, cut carbon emissions, and inspire the next generation. With costs falling, grants available, and payback periods as short as 6 years, there has never been a better time for schools to invest in solar power.
