Veolia developed the site in Ockendon with technology provider REG Power Management using PV modules.
The site uses around 107,000 bi-facial solar modules, each rated at either 540Wp or 545Wp. These modules absorb light on both sides to maximise the power density and are linked to inverters that convert DC to AC electricity. This is then fed to the grid via an on-site 132,000 Volt transformer that is connected to the nearby Warley substation. It also provides the potential added benefit of embedded power use on site.
Donald Macphail, chief operating officer – treatment, said: “The project also has greater significance as the solar arrays have minimal ground level impact, so the wildlife that has repopulated the restored land can continue to coexist with the technology.”
This additional renewable capacity adds to Veolia's existing solar energy facilities Ling Hall, Warwickshire, and Netley in Hampshire, and other solar power installations covering hospitals, offices, water treatment works and recycling centres.
