I was investigating the possibility of getting a solar panel to help keep my battery charged. I have a small boat (22ft.) which doesn''t use much electricity, but I do use it ( nav lights, anchor light, vhf, etc. ) I plan on making a number of weekend trips next summer and do not want my battery to die on one of them
my question is
1. do I really need a solar panel in the first place?
2. how big a panel do I need ( I know nothing about elecrical ampage/voltage) to help keep a single battery charged? or at least lessen the amount of use from the battery?
3. what is the best type of solar panel to put on a small sailboat?
Thanks for the help
