First thing you need to do is get a handle on your daily load requirements. I would suggest you reading some of the stickie notes in the off-grid section, this should get you moving in the right direction, cheers and good luck with it.

You may want to look at the "sizing your battery" post that I attached below.

Being able to generate power when the sun shines is a relatively short duration even in the Summer (5 - 6 hours). So you will want to get a battery charge controller that will work with your DC step down equipment. Also that 100 watt "panel" will not be able to provide enough amperage to charge your car battery. It might be able to keep a float charge on it but that is about it.
