I looked in detail at solar pv during the summer and chose not to go with it. The case is totally reliant on continued government (i.e. our) financial support, and if things get sufficiently crappy that will not survive, and could change substantially in the review due in 2013. Also, I have had contact with someone locally who was getting way below the specified output, even during the really sunny May/June this year(remember that ??).
I support the idea, and have had solar thermal for over 20 years, but I’m waiting for a few more generations of pv panel technology, and increased production volumes, to make it financially sensible.
Oh, and re the OP, if you want to do this I don’t think you need someone to broker it for you unless you can’t raise the cash.
