12 volt wiring

hi experts

I'm planning on installing 3 x 3 watt led lights and possibly a usb charging point in an off-grid holiday let . They will be powered by a gel leisure battery via a controller attached to a solar panel. The runs aren't that long - maybe 3 to 5 metres each. I just wondered what size cabling I would need for such low loads?

Many thanks

The one installed by your electrician - I doubt that insurance policies and public liability issues will allow you to DIY electrics in a property you rent out.

Depends on the total load, but unlikely to be less than 1.5mm²
