Hi,
I'd like to install 4 panels 450 Wp for MPPT 150/40, however, due to the size of the South-East oriented part of the roof, i cannot mount them all the same. I would need to mount 2 vertically + 2 horizontally. Is that ok? Or must all be oriented the same? I guess, it is not problem, I just wanna be sure.
Since I need to instal 2 series, 2 parallels, does it matter how I connect them (the vertical and horizontal) or not? Should the horizontal panels be connected in series and vertical in series or I can mix one horizontal and one vertical in series?
Thanks,
Jakub
