"stmbtwle" I am referring to my earlier post.
21 panels lg365w 18% efficiency vs 21 panels lg365w 21% efficiency.
So it's same output but a little higher cost for more efficient panels.
The way I look at it is less time to produce the same amount of power. Correct me if I am wrong.

The more efficient panels will produce more power PER SQ METER, so for the same wattage will be a bit smaller physically.

Watts are watts, at the same wattage they will produce the same energy in the same time.

Yes I see the specs.
It is a bit smaller and lighter.
So unless there's a architectural reason like load bearing issue I don't think it is worth it. Also each panel is about 1.5kg lighter which will not solve the load bearing issues anyway which has to be fixed first if it comes up.

This kind of answers my questions partly, it's just that I have an option available to do it before it goes up on the roof.

The full Lucky GoldStar part number would be helpful.

LG365N2W-B3 is a 72 cell panel with a Voc of 48.4V
LG365Q1C-A5 is a 60 cell panel with a Voc of 40.2V
Either one will work, just make sure you choose a compatible charge controller.

Currently it is supposed to be solaredge 7600.
SE7600A-USS with LG365N2WB3
I am not sure if it would be advantageous to shell out more money to get the same output with little more efficient panels.

The LG365Q1C-A5 is 10.25 inches shorter in length. Unless you need to conserve real estate, I don't see any advantage.
