On a related track, John, somewhere you wrote down:
"It's alive!
"It's so easy to carry a roll of reflective mylar film that increasing output by 1/3 or 1/2 may be realistic."
I say, a sunny blistering job this is.
"Now it's time to figure out how to make them portable, either folding (say using plastic hinges) or easily assembled from modules to panel."
"Anyone have any slick but cheap and easy ideas?"
I like you are asking for "who" to help. And never forget, reality demands it of us.
Cheap idea: Start with any view of what's "slick", and reflect. Then reflect on "easy, then cheap, then plastic, then folding, portable, and end up reading it all through the other qualifiers again. You already asked for who and how and if and then.
Change "how to who", "who to "why". and cycle, changing the qualifiers to head up your statement with "where/what/and when.
e.g.- Now it's time to figure out WHERE to make them portable...When to make them...what to make portable.
On such a powerful encompassing statement as you wrote, cycle awhile, a minute, a moment, a space in time, a day, chew on it, whatever.
Take that mental pressure off of "how". Let your vision be tentative, with no "therefore" or "then".
"How" is reality, John, it's the real world in total, DIY or not. How will it happen to become real?
All the qualifiers either will or will not validate your best IFFY choices for success.
Putting a man on the moon was/is/will be/ IFFY. Some stuff in life is very tentative and conditional.
You are trying to engage the "rule of your" thumb, and prove how light is the way.
Slim pickings, true, but a relevant choice will always surface like a lotus blossom.
Best thing is, whether single-minded or scattered, each case solves easier by cycling the statements, knocking holes in there so the whole statement can breathe.
We (all) breathe life into a baby. In science and art, the fruit hangs all the way to frog level, the elemental place one can pass through at will. A place which hops with activity.
Does this "blowing a hole in the end of the tunnel", do it for you? See a bigger light?
Hoping so. You obviously see, the light is the real revelation, and the light reveals.
How? By Endless Sphere alone? I think not, John. You're on the path, pointing facts back to the crew.
Is this elemental? Is this, like, a worthy compass?
That's all, for now.

Too far out there for me. I was just soliciting ideas, but too late.
For my "slick" connection of modules I decided on fabric for the hinges for solid connections adding very little weight and thickness to the folded up string. Then I'll put loops at the edges to run fiberglass tubes through to both join the strings to each other and support in the vertical direction. Elastic loops at the outer edges will accept the notched ends of several horizontal tubes to bring it under tension and give the entire structure some rigidity. Triangulating the legs will bring it all together rigid and strong with an adjustable angle. Add a few simple ground anchors and/or bungie it to the parked bike so it doesn't blow over and it's ready to charge quicker and easier than setting up most tents.

I can usually get there, but I'm so practical oriented that I stay up around the surface though never superficial.
Not really knowing each other, you might wish I was the same as you, yet I may be differently oriented and the same, simultaneously.John in CR said:
A forum waits to weigh in on all else, and this forum knows what you are doing is following their own rough standards, or fine standards, of success, in the case of Justin and those with yourself included, you (all) have activated the mainline expression of electromotive transportation.
Where do I come up with these long drawn out pieces of drivel anyway?
I'm watching and it's time to zip it awhile...again. Go shovel snow I guess. lucky devil (sigh).
Any progress on this? You are quite right in that many of us would love to charge our ebikes on solar. It's not the economics of it, as a full charge only costs me a nickel.
I have a cellman a123 pack that I charge with a 58.4V charger. The pack has a BMS. If only I could just build a PV panel of slightly higher voltage and attach it to the pack. Perhaps I need to place a controller in between the two for safety. Seems so simple. But I still have some reading to do...
