Off grid connection for a shed.

New to renewable energy? Have questions? Here's a great place to ask them and view information about wind and solar power basics.

Thanks for that Gordon.

So 2S + 2S it is for now. I was thinking about the amperage produced rather than the voltage drop. It will be
easier to put them in series anyway.

I have about 63m2 of roof space so there's not a lot of room for panels anyway. However for what I want to do it should be fine.

It is volts X amps that is important, and it's best to minimise the high current flow cable length, so PV to CC is best done at higher voltage (panel Vmp) and lower current, and the shorter length CC to battery cable is done at battery voltage and higher current.
