Clarification:  For the 2-radio contesting system, I use two 6V 210AH 
Golf Cart Batteries in series. For a single radio setup, I used a single 
12V battery of the biggest that Costco sells, about 80 AH.

Solar is useless for me during the winter because I'm surrounded by VERY 
tall redwoods, whose shadows limit my sunlight at panels to a few hours 
per day during the winter and 6 hours during the summer. Those with more 
hospitable light exposure may be able to make greater use or szolar 
power. :)

I run all the 12V gear from this system -- K3, P3, preamps for 
Beverages, switching for antennas, etc.
