Rushcliffe Solar

Rushcliffe Solar started as a Transition West Bridgford campaign to encourage greater use of Photovoltaic home power generation systems in Rushcliffe borough, but we are always willing to answer an enquiry from other towns in the region. There are many buildings and entire streets with roofs which have a good view of the Sun and could produce power for the Grid and Income for the occupants. Hit the You Enquire tab to get a free appraisal of the photovoltaic potential for your building. Email: RushcliffeSolar@gmail.com
If you are thinking about it, do not be put off by recent changes in the tariff!: Since April 2012, the tariff was reduced to 21 pence/unit and ones on poorly insulated buildings get only 9 pence/unit. There have been further reductions since. Use the Expertsure calculator to check out your house and see if it is still worth doing.

Concentrated PV efficiency

19 Feb 2012: Hope for those with small roofs is on the way - Concentrated PV (CPV). These Semprius panels are based on Gallium arsenide not Silicon, and each cell is a tiny unit that has a lens in front of it to concentrate solar rays. The tiny units are only 0.1% of the surface area, the lenses bring the light down to them. They are claimed to achieve 30.9% efficiency compared with the 8-15% that we are used to from the current generation of panels. See also the Semprius website. This isn't a far off technology in a lab, these will be coming onto the market, and the commercial production starts in late 2012.
