Blue Solar MPPT 100/50 best solar panel set up ?

Hello community

My current set up lay on 12V battery bank with MPPT 100/50. 5 solar modules connected as parallel due to not even in specs in wattage... maybe that is wrong. 4 modules are same specs (12V/75Wp) and 1 module is 12V/200Wp. According controller capacity was thinking to add one more panel of 12V/200Wp, reaching max wattage controller capacity. Is very much appreciated if you instruct me for best string/s connection layout, in order to minimize cables size and maximize efficiency ?

Thank you in advance

@ArisMad

What is more important than wattage is the VOC of the panels and the isc.

An often in combining two different sizes there are losses, unless you can get the VOC of the two strings together are close.

Looks workable :).

OP, the Vmp has to be similar for this to work successfully.
