Some 628 of the company’s Q.PLUS-G4 modules have been installed on the roof of Doncaster Rovers’ Keepmoat Stadium.
The 178.9 kW array joins an existing 50 kWp array that was supplied in 2013 to create a total rooftop PV system of 228.9 kW.
The project – carried out by Oakapple Renewable Energy – also marks one of the UK’s first subsidy-free commercial power purchase agreements.
Doncaster Rovers play in League One of the English football league. The stadium became the first professional football ground to adopt solar in the UK the 50 kW array was installed.
Since then, the club says it has enjoyed annual electricity bill savings of more than £3000 per year and annual feed-in tariff payments of more than £6000.
The power purchase agreement enables the club to directly purchase the solar energy produced at rates 25 per cent below grid-supplied energy prices.
The solar modules will allow the club to pay £0.085 per unit of electricity under the new PPA, compared to a previous price of £0.110 per unit.
Sean Collier, Head of UK sales at Hanwha Q CELLS said: “The reliability, high efficiency and high power output of the solar modules will ensure that the club can continue to enjoy affordable and clean electricity bills for many years to come.”
He added that with the news last week the UK feed-in tariff for new installations could close in March 2019, “it is vital that flagship projects such as this one lead the way in transitioning the UK solar market to a post-FIT, sustainable and profitable PV landscape”.
