I have nearly concluded discussions with my tutor RE: Thesis and agreed that it will be related to incentives associated with micro-generation and more specifically the Feed in Tariff (FiT) introduced in April 2010. It was also agreed in order to keep the dissertation manageable I should focus in on one of the technologies and therefore photovoltaic (PV) was chosen.

The main hypothesis/suggestion is related to the amount of return on investment (ROI) small investors like me are gaining in the first year of installation – for example July 16th 2010 to July 15th 2011 = 3,511 kWh and an approximate return of £1,750/£15,500 = 11.3% (reduction required for whole life costs such as replacing the inverter ‘say’ every 10 years). http://energy1.moonfruit.com/

To ensure this study is factual and robust I am hoping to find likeminded people to supply me with their 12-month ROI (confidentially) to ensure I can build up an accurate primary data sample based on ‘actual’ generation details and installation cost and not just assumed cost of installation with forecast generation.

If you have a PV installation that is 12-months old or will be by the 31st March 2012 I would really appreciate your help with this study.

Information required:-
1. Size of system and installation cost
2. 12-months generation please

Thanks in advance.

The fairly rapid growth in companies prepared to "rent" roof space, in return for the FIT payment is another good indicator that the return is high.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118522#Comment_118522 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118522#Comment_118522 Thu, 06 Oct 2011 19:14:36 +0100 rondurrans https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118523#Comment_118523 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118523#Comment_118523 Thu, 06 Oct 2011 19:25:50 +0100 jamesingram 4kW jobs are currently around £10-13,000 inc vat now ( ebay has people offering 4kW below £9K)
giving say a return of £1,600 pa for a SE facing system.
larger installs I believe are below £2,500/kWp

One question , was the intended return, set by the government, designed at 8% to including return of captial ( like a savings account ) or just simple straight return.
If the return level was after recovery of installation costs then it's still around 8%
( £12,500 cost / £1,600 FIT+export+ electric saving per year = 13% simple return )]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118524#Comment_118524 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118524#Comment_118524 Thu, 06 Oct 2011 19:28:44 +0100 jamesingram http://www.navitron.org.uk/forum/index.php/topic,15115.0.html
you've probably all ready clocked it.
I'll have a years data of a system in feb. next year , if it's still of use to you
out of interest they've already excede the SAP and PVGIS estimate for annual output with 4 months of winter generation to go.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118531#Comment_118531 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7902&Focus=118531#Comment_118531 Thu, 06 Oct 2011 20:54:46 +0100 rondurrans
