World’s largest FLOATING solar farm built on UK reservoir

World’s largest FLOATING solar farm built on UK reservoir world’s biggest floating solar farm has been built on a reservoir in Britain.

Built on the Queen Elizabeth II reservoir in Walton-on-Thames, the array features 23,046 solar panels and measures 57,500 square metres (618,925 square feet) in size.

The panels are not visible from the road, and the only way to see them is if you are flying above them from nearby Heathrow Airport, or live in a high rise block nearby.

The reservoir is run by Thames Water and the farm is being funded and operated by solar energy company Lightsource.

At a cost of £6 million, the farm has taken three months to build could generate enough electricity to power 1,800 homes – a peak power output of 6.3 megawatts.

The panels cover around 10 per cent of the Queen Elizabeth II reservoir and are not considered to have any major environmental impact, as the reservoir is primarily aimed at supplying drinking water. 

Keeping the pontoons of solar panels buoyant are 61,000 floats and 177 anchors.

The power will be used by Thames Water to power its water treatment plants.

An advantage of floating panels is that the water has the welcome benefit of helping to cool the array.

Unlike on land, the solar panels here did not require any planning permission, and they have the added advantage that their installation does not result in any agricultural being lost. read more at
