Hi I am hoping that there is a grownup that can help me.
Me and my big brother are working in the garden. Well he's working I being my usual Little self a finding things to play with. And for him to look at.
Any he asked me to work out how much solar wiring we will need to put in some solar powered lights.
It about 20 feet away from the house. Will we need a return.
Thanks for any help.
