It is probably a bit lazy of me to post this question on here, but I have been concentrating on solar thermal up until now, and was just wondering how much a 'typical' domestic PV installation would cost.

By-the-way. The topic should have been spelt 'typical'

Nothing like a straight forward answer

I had a 1.44kWP system installed for £4,450 after claiming back the LCBP grant, its MCS so I'll be able to claim FITS (when the government makes its mind up on the price). I believe Billy and others have probably managed to get the cost per Wp even lower but again until someone somewhere see's sense the DIY option is at risk of not being eligable for the FITS programme.
Have a read through the show us yours section and the PV section as many people have indicated the size and cost of their system therein. The price is very dependant on what your personal circumstances are with regard to location, power consumption, end use for generated power etc etc.
Hope this helps a little

I know that is not much help , but i wonder ,if it would be possible to get quotes from Germany as well to be installed in the UK
Prices there are for 5 kw upwards installations (all inclusive ,panels, inverter , mounting excl Vat )
from 2300 to 3000 British Pound per installed KW

Hi Managed to get MCS installed system, with grant, for £3/w. I found a flexible installer that enabled me to do some of the work to keep costs down. They connected everything, tested, set to work and provided all the documentation. Iain http://www.navitron.org.uk/forum/index.php/topic,8417.0.html |

I just had a quote for a 2.88kwp system for £12500.
Take off £2500 grant = £10000 = £3.47/w.
They reckon on installing in a day- interesting.

itsnewtome - that's very similar to me: 2.88kWp, originally quoted £12,500 but finally £13,000 after reviewing site and adjusting for scaffolding requirements, so, £10,500 after grant = £3.64/Wp.
Took a good solid 2 days with 3.5 people so if they can whack yours in in a day that'll be offically 'brisk'.

I think the term 'Whack it in ' is probably right. Considering where the fuse board is in relation to the roof space. I suspect they would simply drill out through my pvc door frame and seal it with loads of mastic. Then up the front wall of my house with a few clips and in through soffit.  Not my idea of a nice job. I only used them for a fact finding mission which was very helpful  |

Another point of discussion.
When the company gave me a quote they also gave an estimate for predicted output.
It was under the heading SAP Calculation which was as follows
2880(wp of system) X 1.1 (solar radiation for my area(1100kwh/m2) x 97% (my roof is approx 3derees off os south = 3072kwh/ annum.
Having looked on the SAP 2005 document I believe the calc should be as follows
0.8 (each kwp produces 800kwh approx) x 2.88 x 1042 (solar radiation at 30 degree incline) = 2400kwh/ annum
None of the above take account of any shading.
This is a difference of over 25%.
Which is correct?

Where in the UK are you? In Cornwall its about 1MWh/year per 1kWp installed capacity, and it goes down as you go up country. Jonathan |

Lots on my system, but most installs on the forum this year are around £3.00-£3.50 per watt peak. I expect c 850kWh per year per 1kWp installed but if you are in the channel islands you might get 1100. Cornwall is the best place on mainland Britain but SW Cork where Billi is might be a bit better? Look at PVGIS that seems to be the best respected estimator tool at present.
