As for the solar panels, I use a 100W Renogy solar panel, which connects to the generator giving it a pretty quick charge, given the right amount of sunlight. I have used these in conjunction with each other a number of times in different scenarios and have to say that together, they are worth the investment. In fact, the two of them together are still cheaper than most quality generators and are more sustainable to run.
This is a very interesting premise, but the episodes get tiresome as the format is increasingly repetitive. Also, some really obvious mistakes that the preppers make are sometimes ignored: shelves full of glass bottles at eye level (no lip on shelves) in preparation for a major earthquake? Also, the one issue preparation (climate change, economic collapse, Yellowstone blowing up, etc.) seems tunnel-visioned, but apparently the shows' writers need that statement as a justification for their script. The fact is that most of the preppers and the needed preparations that each makes are very much the same in the outcomes they're working toward.
We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor[76] for any natural or man-made disaster[77] and "a clever way of drawing people’s attention to disaster preparedness".[76] The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything."[78] Though "there are some... who are seriously preparing for a zombie attack".[79]
There's 1 small thing and 1 large thing that, for me, saved it from being a 1 star. First the small thing, the mention of herbs and spices - I think this may be an item that many people forget about, but can make a poor situation go from "surviving" to "doing good". Secondly, the section on entertainment and education - I think this is an oft-overlooked aspect that will actually be very important, and again will affect whether one just survives or thrives.
2- Listening to these people is an exercise in restraint. They are largely uninformed and base their life-decisions on anecdotal information they glean from the internet and other like-minded people as equally ignorant. They lack the imagination to redirect their energy and efforts to endeavors that could benefit society. Their apocalyptic view of the world is unsupported by real-world events, think Katrina, Sandy, and Fukushima, and provides them with a platform that simply reinforces a mistaken belief that all Americans adhere to or support this behavior.
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
