Having non-contiguous panels?

Hi

I've a load of sky lights on the roof. Is it possible to have a panel here and a panel there and connected by cables? Or is there a requirement to have them all side by side? Thanks

Nothing wrong with that except you might see cables all over place but if they can be pushed inside you can connect them there and leave the outside looking neat. If not I'm sure some trunking can be used as well.

Nothing wrong with that in the slightest, I have 7M between panels on one of my strings, DC does not drop as much as AC on cable runs

Come to think about it I have 2 panels connecting to other 10 on the same string with 9m DC cable and no problem at all.

What do you mean DC does not drop as much as AC on cable runs? why would there be AC? and typically doesn't DC drop more on a length of conductor anyway?

I mentioned AC as some folk have their inverter beside their (usually ground mount) panels.

AC loses more voltage over long runs as it experiences inductive losses which DC does not

Ok, there are inductive losses with AC, but does AC loses more voltage loss over long runs? maybe it depends on what you mean by long runs? maybe it doesn't matter in the distance of a solar panel set up, but I always thought DC required a larger cable to distribute the same voltage without experiencing losses,

Having non-contiguous panels?
