Hi Everyone,
Just wanting to pick your brains.

I was talking to a mate of mine about using a solar panel to recharge/trickle charge the 100amp battery my camping caravan.

The next day he gave me a new 20w mono crystalline solar panel.

I have bought a charge controller from Jaycar which drops the voltage to 12v, as the output on the panel is 17.6v.

Will this set up be enough to trickle charge the battery in the van? The only items running off the battery will be lights, soon to be converted to led, small water pump for the sink and the occasional charge of portable lighting.

The battery is set up to charge while driving, so the battery should be fully charged upon arriving at camp site.

What do you think, will this be enough or do I need more?
