Some of the newer technologies offer better charging with lower angles of the sun. This is the reason for the primary difference in price. Also, flexible panels can run a lot more money. Of course, there are those manufacturers who like to have higher margins. So, it pays to look closely at the specs. We installed two LG panels and are very happy with the performance.

I've been scouring this group and the web looking at what solar panels to get. The various brands appear to all offer very similar specifications yet the price variance is huge.
For example an LG 330 NeON 2Black panel is UK£223 vs. the Trina Solar, 335W Half Cut Mono Solar Module at UK£109 (all exVAT). 
The only significant difference between the two brands that I can see is in the warranty performance after 25 years: LG warranty is for 90% of initial spec'n vs. the Trinasolar's 81%.
I see some of you have bought LG, someone else has gone for Watts/£ and Bisol. Has anyone discovered any major difference between the brands? Any recommendations?
