Where did you get to on your investigations?

I've had BG come around today and recommended an array of 10x 230w
panels (all that will fit on my roof because of Velux windows in the
way).  I also will have a little shading from chimney and blasted great
trees.

The guy did say though that the panels (Sharp I think he said have
increased in power in the last three weeks from 210w to 230w but are at
the same price.  Reckons a tad over 10k for the 2.3Kw.

The only worrying thing was that he said the FIT was 41p/Kwh, I had to
show him the ofgem page that stated it was 43p!

I'm also looking to HA it all somehow....early days of thinking about it
though!

installer coming tonight so I'll be quizzing him a little more about this

by the lowest producing panel, that's means if I have a string of Sharp
panels all producing +10% but the last one produces -5% then its as though
all the panels are at -5%.
