12AWG, 20 amp is good.

I a house thats true
But by the charge controller amp if its matched to the panel , a 100 watt panel amp out put max is 5-6 amps , if your charge controller is 15 amp and you might add another panel you could use a 15 amp, 30 amp might not protect if there a problem

I agree with what Okan-Star says. The thing you are protecting with the fuse is your solar charge controller. I know a number of TC manufacturers for a single panel use a 10 amp controller. That is fine for a single panel, but not for a dual panel. So if you are thinking you will upgrade in the future, look at what solar charge controller that you select first. You probably want something like a 20 amp controller. Also look carefully at the available features for the controller. They are not all the same. Mello Mike has a good blog on solar HERE

DJ,
For my solar power system, I have a 30amp fuse on that wire which is 10AWG.

Fuse size is dictated by the wire size. How big is the wire?

12AWG, 20 amp is good.
