PV Panels is there a big difference in them all

[slingshotjim]

Hey Ho, Thought I might risk the 3rd March deadline and put a 4kw kit up, been quoted £7750 fitted for an LG or Hyundai kit, then I have a look about and there are loads of different ones, is there a difference in them, has any one actually checked in real situations one from another in output etc, only got max 2 weeks to decide,
Cheers for any input. JIM

different efficiency's and big difference in price thats a good price for 4kw, Both good panels I wouldn't look about for too long as there's already a shortage of kit you might end up with cheap chinese carp.

My mate fits various panels at various prices which can range from 5 - 12 thousand for the same output sothere is obviously a difference
