Thank you for sharing your knowledge. This is an area I have been feeling a great need to learn more about, but can't seem to grasp for some reason. I only just recently finally got enough of it to sink in to get myself set up to be able to use a 24w foldable solar panel to charge a bunch of 18650 batteries that run my 2000 lumen flashlights that I use constantly day and night due to my vision problems.

It will also be enough to keep a tablet operating so I can use the tablet to view several thousands PDF's I have accumulated with knowledge to help start over after a total disaster of society.

This could be a back up to what I already have, and allow for a few little luxuries perhaps. Thanks again for posting this and please do go into as much detail and talk about any and everything dealing with solar and batteries. There are lots of us trying to learn but most websites talk as if they are speaking to engineers or something.
