North vs east facing solar panels

[Marty]

There are situations where this works @David_Arulanandam, which I was also quite surprised about. See the relevant thread here:

Solar Power Blacktown NSW

Yes no worries installing panels in two different orientations (east and west) in parallel on one MPPT. The strings just have to be the same length (exact same number of panels). It’s quite common to do this when roof space is limited. Best to go as big as possible and install all 6kW for your situation.
