Solar panels on schools
In 2024, the government announced that 119 schools across the UK needed to be rebuilt due to the use of Reinforced Autoclaved Aerated Concrete (RAAC) in their original construction. While this presents a significant challenge for the public sector and its budget, it offers an opportunity to make improvements such as installing solar panels.
What are the benefits of solar panels for schools?
With electricity costs rising, school budgets are under greater pressure than ever. In addition to this, the Energy Bill Discount Scheme, which was designed to help certain educational institutions pay their bills, was closed on 31 March 2024. The benefits of installing solar PV systems while rebuilding schools are therefore manifold.
- Lower electricity costs
By using the sun’s power to generate electricity, schools can enjoy reduced energy costs. Depending on the size of the installation, part or all of the establishment’s energy needs can be covered during daylight hours. This enables schools to direct their budget where it is needed most.
- Reducing carbon emissions
Solar panels provide a chance for schools to make a significant contribution to climate action. In 2024, several schools in the southeast, for example, saved emissions of between 5,053kg and 11,683kg per year thanks to solar PV installations. This not only helps the environment, it offers educational institutions a chance to set an example to pupils, demonstrating care for the planet.
- Educating pupils
While the solar panel system is being installed, schools can use it as an opportunity to teach students about sustainable energy, the materials used in solar panel production, and installation processes. As a result, children can develop an interest in physics, the growing sustainable technology sector, and other areas of science.
Cost of solar panels for schools
A barrier for many schools is the upfront cost for installing solar PV systems. According to GreenMatch, a 10kW system – which would reduce a school’s reliance on the National Grid – costs between £13,000 and £15,000 on average. A 20kW system, which could meet a school’s energy needs completely, typically costs between £16,000 and £30,000.
The upfront cost, however, is offset relatively quickly compared to domestic solar panels. Schools can break even on their costs in as little as six years, meaning any electricity generated thereafter is free.
There are a number of funding options that schools can take advantage of too. These include Salix Finance, which provides government funding to the public sector for energy efficiency improvements, and Energy Efficacy Financing (EEF) and Power Purchase Agreements. Schools can also sell excess power back to the grid under the Smart Export Guarantee (SEG), helping them to break even more quickly.
Installing solar panels on schools
With over 100 schools requiring reconstruction, there is a prime opportunity to incorporate solar panels into the process and deliver long term cost savings. The benefits include greater energy independence, lower bills, reduced carbon emissions and educational opportunities for pupils. Schools can discuss their needs with qualified and regulated solar PV installers before committing, and with a range of funding options available, sustainable power is achievable.
