Costco has a hundred watt foldable solar panel that supposedly puts out 18V. On a dollars per watt basis, it is not a great deal, but it is very easy to store and deploy, so I am willing to put up with the cost. (I already have a 120 W suitcase panel -- this new panel is for emergency use at home, as well as extra juice while camping.)
My question, of course, is that I want to use this panel to charge a 12V battery. There has to be an after-market controller that will do the job. Given the specs of the panel (see link below), which controller do you recommend? Thanks in advance for your wisdom.

Any PWM controller will work. Pick one for a simple setup like this, probably the least expensive one will work. Amazon has them as low as $10. A controller from a well known Mfr (Renogy) can be had for less than $20.
