Ok, thank you for your replies.
Now I understand why they install the equipment in the loft not to have to deal with the Voltage drop.
In this case wouldn't be better to just have two separate systems and merge them at 240V to be able to transfer electricity at longer distances.
It's just a hypothetical question and out of scope of the current discussion but currently I have a 10mm SWA in the ground and this is to bring the electricity to the garden but in the future could this be changed to bring the electricity to the house from PV system? Like a kind of evolution from grid to semi-of-grid.
