British Gas is set to fit 750 schools with solar panels worth between £20,000 and £40,000.
The panels, which will be installed for free, will allow the schools to generate green energy, cutting as much as 20 per cent off their annual fuel bill.
The money saved will then be used to finance the installation of panels in more schools in the hope that, within five years, free solar panels could be installed in as many as 1,100 schools.
The scheme is set to reduce emissions by up to 1,400 tonnes annually.
British Gas spokesperson Katie Alloway said: “”A school is the hub of a community, used by so many people, so the opportunity to have a solar panel and showcase that technology will really help them to understand more about the technology and how they can cut energy use and save money.”
