MLS-100WP is a 12v 18v 100 watt polycrystaline solar panelDimensions: 40 inches x 27 inches x 1.40 inches. Pre drilled diodes in junction box and a pair of 35 inch cables with MC4 connectors already attached to the panelHigh efficiency solar cells based on innovative photovoltaic technologyStrong aluminum frame manufactured to withstand a heavier snow load and high wind pressures, passing a snow load of 5400Pa.Pre drilled holes on the back of the panel for fast mounting and securing
My solar set-up was this:
This 100W solar panel was mighty for my 12Volt 15AH SLA batteries, and is used for RVs typically. It did the job well even in overcast skies.

You'll need a controller so you don't overcharge your battery or fry any electronics you'd like to attach. I used one like this(the one I bought is no longer posted):

The controller attached to the SLA battery. You can then either charge the SLA, remove it from the system as needed, and use it for other things (as I did), or leave the battery to hold power for your various electronics you may be trying to power at your camp. I had a battery for my electronics, but would swap it out for my ebike batteries when I needed to charge them.
I had an inverter connected to the controller so I could plug things (mainly a small fan) into it.
Inverter. I cut the cigarette charger off and connected the wires to the controller: https://www.amazon.com/gp/product/B004MDXS0U/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
Here's a diagram that will help visualize how these set-ups are typically: https://s-media-cache-ak0.pinimg.com/originals/63/6b/f5/636bf543aa56b79c556a2c8a1b216461.jpg
Charging batteries in series is doable, but not advisable because they don't tend to charge evenly. IE: The first battery gets more charge and the middle one doesn't get totally full. If you charge them separately you can make sure each is charged fully. This PDF describes the whole concept in more detail: http://www.thunderstruck-ev.com/images/Charging%20in%20Series.pdf

I'm looking at this refrigerator, which draws 43 W.
And this solar panel produces 100 W.
If the solar panels can produce more power than the refrigerator requires, wouldn't it be possible to power the device irrespective of the voltage/amperage, since I can convert the voltage/amperage with converters and all?
Ah, its pretty important that solar panels get direct sunlight. they get quite a big efficiency loss in the shade.
You would want a solar charge controller, something like this and a solar panel, something like this
The ones I listed are just the first hits on amazon, i dont have experience with those, so do some research :) I think that will work with a motorcycle battery but i might be wrong.
BTW, how about a really long extention cord... like 100ft+?
