Well, do the math. How much power does a coolatron require?
Plug the data into the Handy Battery Demand Calculator
http://www.altavistaaudio.com/Westy/Vanagon/battcalc.html
and see how many ampere-hours your battery will need to supply, and from
that you can see how much power the panels will need to stuff back into
the battery during the sunlight hours.
