Last month the University of Greenwich installed an array of photovoltaic solar panels that will be powering some of the student residencies at the Avery Hill Campus. The panels have been installed in time to benefit from the higher rate of the feed-in-tariff before the incentive was reduced in December. They now have been generating electricity for four weeks (at a time with the shortest amount of daytime) and have so far generated: 1,106 kWh this has given the University a combined total saved/earned of £485. On top of this the electricity generated is enough to power five student flats for a week in Aragon Court, (electricity, heating, hot water, the lot!) and all in the gloomiest weeks of the year.

In fact the return on investment for solar is so good that we have seen a few people putting up arrays on their private property. Jon Hudson of the Building Services Team has a small array of 6.5 kW on his house and when John Bailey went back to the west country for Christmas he noticed his mum had popped five panels up on the roof there - not quite the 190 odd we have up on Avery Hill but enough to turn the meter backwards when all the lights are off.
Kevin Behn from Human Resources, who is currently looking forward to starting work on his new allotment and getting on with some D.I.Y, has recently installed some solar panels on his house - and just in time to receive the maximum feed-in-tariff rate. Kevin has managed to get eight panels on his roof, an array that should produce around 1700 kWh per year, and is expecting to see the panels pay for themselves in eight to nine years, after that he still gets the feed-in-tariff for a further 16-17 years and any electricity generated then will be producing a profit. Kevin added a cautious 'wait and see' on his estimations but said that he 'is more than staisfied' with the panels so far. Like Kevin we'll be hoping for a sunny 2012 here in the Sustainability Office and hoping that everyone's solar panels perform as well as we're predicting!
For those who are interested in finding out more about solar power and generating electricity and energy from renewable sources, the School of Engineering has a solar array consisting of five varieties of panel at the Medway Campus. The School have been testing the panels to see which ones produce the best yields when harvesting the sun’s energy. You can see the panels when you wonder up to the Wolfson Centre and can find out which panels you should be choosing more by contacting Ian Cakebread at the School.

May the sun shines on our planet always & keep it eco friendly.
