Yea you can get combiner pigtails to chain a bunch together in series or parallel. Depends on max amperage and voltage of the solar input. Read up and plan it out before you buy all your kit

Yes but it is almost universally better to buy a normal aluminum frame panel unless you absolutely need it to be folded up. The portable panels are heavier, larger, and tend not to perform as well.

The best bang for the buck is almost certainly going to be to buy a single 440w residential size panel and store it when not in use. You can find these for between $50 used up to around $130 for a single new panel.

Hopefully, the adapter cable isn't as shown in the image, which has its receiving MC4 connectors' polarity reversed. EEK!

Please explain why, when, and if you buy 2 of the same 100Ws, you get double the number of cables and ease of transportation?

You only need a combiner if you wire in parallel. In series, you just wire 1 negative lead from 1 panel to the positive lead from the other panel, then treat the 2 free leads as if it was a single pair coming off a single panel. Wiring in parallel you need to combine the 2 positives into a single positive and the same with the negatives. You'll need an MC4 2 to 1 adaptor to do this. They are inexpensive. They make 3 to 1 and 4 to 1 and so forth, depending on how many panels you are paralleling together. Why you'd choose 1 wiring method over the other usually comes down to the voltage your SCC or Power station can accept. Parallel wiring, your voltage remains the same as a single panel, but you add the current, or amperage together. Series is the opposite, you add the voltage together but the curent or amperage remains the same. Ultimately, the overall output wattage remains the same as V x A = W. Why to go with one way or the other? Parallel wiring will give you better performance in partial shading. Like if tshade covered 1 panel out of a 4 panel parallel wiring setup, you'll mainly just lose the output to jthat one panel and you'll still have full output from the other 3 but in series, if shade covers one panel completely, you'll lose nearly all the output from all 4 panels so keep that in mind. Series is better if you want to run long runs of wire between your panels and your solar generator or batteries because you can get away with much smaller wire without as much overall loss due to the higher voltage but lower current. Each way has its pros and cons so whats better for the indivdual will depend on each particular setup. A lot of your wiring will be dictated by your solar charge controller and how much voltage it can accept. For example If it can accept up to 50v, then you have to wire your panels accordingly to stay under that limit. 4 standard 12v panels in series will be too much voltage for a 50v max solar charge controller. You'll need to either wire either 4 in parallel, or 2 pairs in series, then those 2 pairs together in parallelI to stay under your 50v limit. I'm probably making it sound more complex than it needs to because it's really simple once you learn.

No no no. Its correct, MC4 connectors are funny like that. the external plastic casing part you see would at first glance indicate its positive (or male) but if you look closely inside that plastic shaft, you'll see a hollow metal sleave and on the MC4 plug that looks negative (female), if you look inside of it, you'll see the metal post that slides into the metal sleave on the other one. For what reason they do it like this, I don't know, I just know thats how its done. It's confusing, especially for anyone just getting into MC4 connectors & especially if your crimping your own MC4 connectors to the ends of bare wires. I added a couple pictures to help show you what I'm talking about. Look closely at the metal pins on the unassembled MC4 connectors picture you can see the size difference and which one actually slides into the other. The other 2 pictures shows some already connected onto the corresponding correct color of wire.

EDIT: Disregard the 3rd picture (the coiled up wire). As someone kindly pointed out, it is incorrect.

It would be a bit more than just a trickle, probably close to around 5 amps or maybe a tad more and you'd need a solar charge controller that would install between the panel and your battery, but it would definitely work to charge a car battery. Just make sure your charge controller is for Lead Acid or AGM, whichever your car has.

How are foldable portable panels heavier than permanent glass residential panels?

The polarity on these cables are correct. The panel itself actually has mc4 connectors on the back and this adapter cable is to adapt to to two various devices like power stations from ecoflow and Bluetti.
