Simple, probably daft, question about splitting one ring of panels into two for the inverter input

[MrTWales]

Appolgies in advance for using the wrong terminology...

 

I have a set of 12 panels, all facing the same way, on a flat roof. They work well but at some times of the day (at the end and start), some of the panels are in shade. In the summer I guess the sun will be higher, but at other times it will make some difference. 

 

They are all connected to the same inverter input, but I was wondering whether splitting into two 6-panel rings would make sense? An installer has to come back at some point anyway, so I was going to ask about this. I was thinking that, as you can get on the roof with just a chair, it's just a question of getting a bit more cable and changing the connections and then poking another cable through an existing hole to the inverter. 

 

But, are there downsides (other than the cost) to doing this? Eg is there more that can go wrong as the inverter is doing something a bit more complicated?

If you can split your panels into groups that are shaded at the same time and this arrangement suits your inverter (number of input connections, min/max DC voltage in etc) then you should be home and dry.

Thanks - splitting the most natural looking was will work for the shade and there is a spare connection. In fact, the form that the installer used to register (he wanted my signature so I saw it) did actually say that it was 2 x 6 panels feeding into the inverter.
