marine solar charger

[monster musky]

Are there any inexpensive options for solar chargers to keep a trolling motor battery charged for a two or three day trip?

What about a small generator? Their prices have really come down.

I've got a regular size panel from one of the big stores. It stays on my boatlift and will keep my 2 batteries charged. Total cost of the panel plus a device to not overcharge was around $100+ I believe. It works but there is always a week or two between using the boat. It would not recharge my batteries or keep them charged over a 2-3 day period.
