RENEWABLE energy business Clean Energy (Yorkshire) has completed its biggest contract to date with a renewable energy installation at Harrogate Grammar School.

The Harrogate business has installed more than 200 solar panels to roofs of the school, which has 1,800 students.

The panels, fitted to two roofs on the Sixth Form block, will generate just under 50 kilowatts of electricity, enough to power 4,500 low-energy light bulbs or 3,000 computer screens.
