Towering 9m high on either side of the main entrance of the Solaris Centre, there are 2 wind turbines. Each one is rated at 6kW and has a rotor diameter of 5.5 metres. The turbines have 3 blades each and are of the "down-wind" type. The installation cost £35,000 and each turbine will generate approximately 7,000 kWh per year. The turbines are designed to be extremely quiet and do not contain a gear box - the main source of the whining noise in large wind farm type machines. At wind speeds above 25 mph, the blade pitch is automatically adjusted to maintain 200 rpm and full output. Wind Turbines (PDF): Factsheet Proven Energy provided the turbines installed at the front of the Solaris Centre. The photovoltaic installation on the Solaris Centre roof is light sensitive and generates an average of 30 KWh of electricity per day. This would power 3 average homes and saves around 5.5 tonnes of carbon dioxide annually.
The full installation consists of 145 double glazed panels comprising 6,870 photovoltaic cells covering a total of 232 square metres.
DID YOU KNOW? Within one hour, the sun provides the Earth with enough energy to power the world's population for a year!
Hopefully every home in the country will have a renewable energy supply to help lessen our reliance on fossil fuels.
