I see that premium panels like (LGís for example) offer better efficiency, temperature drop off, performance degradation and guarantees.

Are they worth the extra cost? Up until now Iíve left the choice of system components up to the installation companies in their offers but Iím wondering whether I should also ask for a Ďpremiumí price. Iím slightly limited by panel size as I want 400W panels and there arenít loads out there.

Anyone been through this process able to help, please?

Today's premium panels are tomorrow's bargain, when tomorrows premium panels go on the market.

Generally speaking the latest-and-greatest panels aren't worth the cost. However it comes down to what you have most scarcity of. 18x 400W panels would cost a LOT more than 24x 300W panels (possibly twice as much!). However if you have severely limited space then your only way to get higher output is more expensive panels. Manufacturer claims of temperature resistance, superior low-light performance, longer lifespans, and other differentiating factors, tend to be imaginings of the marketing dept.

I have 16 Panasonic panel which cost a great deal more than others, however they are smaller in size.
The reason for these been installed was my roof spaces would not take standard size panels and the area that could suffers shading.
Panasonics are/were 1600mm long by 800mm wide where standard panes are 1700-1800mm long and 1000mm wide.

A lot of time was spent by me measuring roof sizes ( made easy as its a bungalow ) and then producing scale drawings with various panel sizes superimposed
I actualy used the windows 7 version of paint and selected the display grid option.

I did post pics of the install but the forum can no longer display the original pics

I can repost these if required
