Hey! I am knew to the solar game, so bare with me. We are moving to a property (UK based) which we intend to be in for a while, and would like to install solar - after looking into it, a grid-tie system (no battery storage, for now) seems to suit our needs.
Our roof direction and available space is not ideal, however with a bit of luck, we’ll be able to get 9 panels on the roof, in 3 blocks of 3 - see image below!
6 will face south west - shown in yellow
3 will face south east - shown in blue
My research so far has led me to the conclusion that I should connect the six south west facing panels in series, and the 3 facing south east in series, with each array into its own MPPT, utilising an inverter with duel MPPT inputs.
Something like the Solis single phase 3.6kw 4g duel MPPT looks like it would suffice.
I am just looking for second opinions on my thinking. Am I overcomplicating it? Would the gains of this be worth it, as opposed to connecting the lot in series and accepting the deficiency?
Any advice would be massively appreciated.
Many thanks
