I envy you Hank because you have so much to learn.
Start with Google
- Marine batteries
- Battery charger
- Photovoltaic cell
- Wind generator
as the search words.
The time it would take to charge your battery depends on how big it is how discharged your battery is when you start and what you use to charge it.
Let us start with a naive example in order to give you an idea.
Let us assume a 100 AH battery and a charging current
of 5 Amps. This will take 20 hours as a first approximation if we start with a completely discharged battery and we can persuade our charger
to deliver 5 Amps no matter what.
