Yeah ya could buy more 5v cells, but won't that get messy mounting them all? 
Stick 'em onto a big flat board or roof with silicon I suppose. Gotta keep water out.
Basic, waterproof and tidy 12v 10watt panel free postage from NSW is $23

The 12v 0.58A current should at least double when converted down to 5v (need
input here)
But even so, 1 amp isn't really enough.
I have a spare 12v 10amp max solar regulator here ya can have for free if needed.
