The Solar Park

Westmill Solar Park is located near to Watchfield, on the Wiltshire/Oxfordshire border, just off the A420. The site consists of 30 acres of over 20,000 polycrystalline PV panels generating 4.8GWhr/year – approximately the equivalent to a year’s electricity consumption of 1,400 homes in Oxfordshire and enough to prevent 2,000 tonnes of carbon dioxide emissions annually. It is, we believe, the UK's first and world's largest cooperatively run, community-owned solar farm.

The Technology

Solar power is one of the most well-established and reliable renewable energy technologies.

Solar power is in operation across the world and installed solar capacity is now above 32 GW globally. Solar Photovoltaic (PV) panels have no moving parts and therefore require little maintenance. They produce no noise, vibration or pollution. Solar PV panels operate even in cloudy conditions and have been installed across the country. The South of England is particularly suited to solar PV due to the relatively high levels of sunlight.
