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.

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.

Register on the BDPV website!

27 Dec 2011: I recently discovered the website  which is a French site, providing a geographical database of PV systems installed all over Europe.  Each user is trusted to supply their own data for each month, and have that compared with others near them, and with the classic PVGIS calculation for that same Lat, Long, Orientation and Roofpitch.

Above is the display for my PV system for the most recent year (2011) with an estimate for the final figure for December 2011 (which is already well ahead of the previous year. The chart shows comparisons with the previous two years.
 It is easy to register with BDPV and there seems no charge for using it. I am surprised at how many are using it already, including quite a lot within a short distance of my home. It is easy to make charts like the above, comparing systems with each other or between yours and others.
  One indication of the effect of the british government's changes to the Feed in Tariff was that many of the UK systems that I browsed when first visiting this site all seemed to have been installed in November or December of 2011.

High Court ruling on FIT changes

24 Dec 2011: It seems that the High Court found that the government were wrongful in pressing ahead with major changes to the Feed in Tariff without considering that the consultation process was not completed, and that the deadlines given have caused untold chaos in the solar installation industry.... and we should not forget some of the inevitable job losses or company closures.
Most people assume that Cameron and Osborne (who seems from his actions and saying to have little regard for the 'Green' revolution) will just carry on regardless of the Court ruling, or of the effects on the Solar industry and customers. 

Why link to Insulation?
When this was first mooted, it was proposed that the higher tariff should apply to houses which meet an Energy Performance Certificate (EPC) of level "C". Although this sounds at first sight like a good incentive, it reveals, at closer inspection to be just another form of discouragement, and favouring the well off house owner.
   Energy Generation is a different matter from Energy Conservation, and both are excellent, but there is No Reason for them to be so tightly linked, or for one to exclude the other. Should we also make a law that "Only houses with PV panels should be Insulated"? Of course not. That demonstrates the absurdity of the current proposal that "Only houses with Insulation should have PV panels". There are other ways to incentivise insulation, and these are being done.
  Society needs Energy, so why should we not encourage panels to be fixed on garages, barns and old houses that are not easy to insulate? In the same way, there are many buildings than can and should be insulated, but because of chimneys, dormers, trees or hips, they cannot be adapted for photovoltaic. 
    It can cost more to insulate a house up to level C than to fix solar panels. This new requirement becomes a charter favouring the rich or the owner occupier, because it requires an expensive operation on the house first, and perhaps a season's delay. 
   What does it do for social housing (especially of older dwellings)? A quick one or two day installation of panels can reduce future fuel poverty for a whole street, but a programme of insulation of a whole street would mean a complex and expensive process of decanting tenants etc. with funds that the local authorities or housing associations do not have.
