Solar Battery chargers

[81scamp]

I found a 3watt and 5 watt solar battery chargers at Northern Tool, anybody ever use one of these? seems like it would be a good idea just to set it up during the day and let it charge up>

It's not really big enough.

I use a 15watt and it just about keeps my dual battery set up charged.

I've got a 15W on mine also just too keep it charged up, I had a small gate charger on it and the power draw just from my charge meter would pull the battery down, I would imagine if you're going to use batteries all the time and use solar panels to charge the battery that 50-60 Watts would be a good starting point.
