Canadian 365w Vs Longi 370w

[razn23]

Which is the better option out of these two for a 6.6kw system?
18 X 365W Canadian Solar (CS3L-365MS)
18 × 370W LONGi Solar Hi-MO4m - LR4-60HPH-370M

Also, is it better to add all 18 panels north facing or 12 north and 6 west facing?
Thank you.

It’s hard to separate those. See here:

Hi @Imp Yes, I agree with Frank there. Probably much of a muchness between these two brands: As Frank says, the installer is the biggest factor as we talk about here: https://forum.cleanenergyreviews.info/t/ch-2-who-should-i-buy-solar-from/155 Cheers Marty

Having them all face north will give you more solar generation overall, however having panels facing west will give you more solar generation in the afternoon. So it depends a bit on when you are using electricity at your home, and what your solar feed-in-tariff is.
