I'd recommend you read this
primer on solar power on boats I wrote.
Then you need to figure out what your rough daily electrical usage is, and how many days of electricity you'll be using. That gives you a rough estimate to base your battery bank on, and then figure out how many days you have between uses....and that gives you your rough recharge time. Base your solar panel sizing on the recharge time and the amount of power you need to replace, but give yourself a bit of a safety margin—20-25% would be good.

I also am wondering how much a solar panel can do considering I may be using the battery a lot. Do you think it could keep up with my use and how many watts would it need to be to do that? Thanks.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
