30%+ moduls are ultra expensive to purchase. As a very rough estimate factor 1,000 more expensive compared to 20%+ moduls.

Energy from solar moduls mounted on ebikes is always expensive, because you will only use a small amount of their potential power Generation and lightweight moduls cost 3-5 times more than standard glass moduls.

If you build a solar bike you do that for a special trip where you travel away from outlets to recharge a battery, you usualy do not build a solar ebike for your daily commute or a Standard trip where you ride from hotel room to hotel room.

Two guys on a team had issues with cracked solar cells, and had to abandon the trip 1/2 way through. A corner of one of their solar panels literally broke off. This is after that panel's protective film had started bubbling in the heat of the day, and had been for several days at that point. Several more participants ran into either full panel failure, or reduced power output, but they were able to replace the panels or resort to wall charging at night.
Thanks for your answer.

The IR luminescens Picture you see above was from a NEW highe quality solar modul bought directly from China.

It still was able to produce 50W of power, but the heavily cracked cells already get a bit hotter if viewed under a thermal camera. If you short the modul those celsl already get very hot, hotter than 100°C.

So if you are riding under a very sunny and very hot climate and you have even more demaged cells very high Temperatur spots way above 100°C are perfectly possible. Many people buy cheap moduls with PET cover and this will melt under such conditions.

As I said this is a new module. ALL semiflexible moduls have those micro cracks when bought new, if you bedn them only one time by 30° you will introduce 100ds of new micorcracks.
The modules may still work nice, but ist cells have been weakend and it will be more senisble to vibration, more cracks, hot spots and so on.

I do not understand why those moduls are advirtised that way.

The module shown in Picture one of this thread has been bent and it will vibrate. I bet it will look horrible broken under IR and while it might still work nice it will not live for long.

I have another question about the Suntrip vehicles.

Rules are that the Motors of those vehicles may not provide power if running faster than 45km/h.

We have that speed pedelec class in Germany with its 45km/h limit but you need insurance for those vehicles and there are some strict rules and it is very difficult to get them approved. In Germany it is not legal to use a solar trailer with them for example.

Are those 45km/h e-bikes used in the Suntrip street legal? Is there a special insurance for them that is good for all countries travled (I see no insurance plates on them) or do you just ride them "outside the law"? Did you not encounter problems with police at least in European states?

Hehe... And yet we seem immersed in a world where manufacturers rely on high volumes with X quantities of the same/identical unit of "the thing"...

The power of choice and impulse buying.

Grocery Stores - Give the consumer too many choices and customer will not buy, give the customer a handful of choices you will get sales.

That luminescent picture is more interesting after you say it's a brand new panel. This is why I think there needs to be a new type of lightweight, yet rigid solar panel to come out, suitable for EV's. ~95% of people out there are not using the bending feature of these panels, because it's been proven through solar car racing that you generally want them flat during the day (unless parked). If we're not bending them, then they don't need to be flexible.

The guy on the Sun Trip who represented his company 'PhotoWatt' I think had the coolest panel because it was A) lightweight, just like your flexible panel, and B) rigid due to it's foam core composite integrated rack. The best of both. Too bad it's not in production.

The organizers of the Sun Trip had good enough relations with the French government to allow some degree of unspoken 'don't know, don't care' attitude at the enforcement level. Now I easily could have missed something that was said in French (that happened a lot lol), but my understanding was that we were going to be left alone along our route because we're 'experimenting with clean transportation,' etc. :pancake:

What are the restrictions on bike trailers in Germany? If on a Sun Trip you may be able to talk your way out of it, but if I lived in Germany and had a solar bike, I would probably go get it registered as a speed pedelec. This costs a little money, but seems well worth it in the long run. I met a man in Switzerland over the summer who frequently rode his e-bike through Germany for work; he had gotten the bike registered in Switzerland as a speed pedelec (I think the limit is 500w there instead of ~350w?), which legally allows him to travel 45km/h. But since he happens to own hands-down the secksiest e-bike I've ever seen (anyone ever heard of SpeedPed, a boutique German mid-drive, which uses a right-hand drive motor belted into an Alfine 8 hub?), he was able to manipulate his bike's power output with the Cycle Analyst. He found that it doesn't matter how much power he's using so long as the speed cameras don't catch him going over 45km/h, which apparently did happen to him, especially when riding downhill, etc. He said he would get a ticket from the speed cam from going even just 48 in a 45. In America, our speed camera's don't sense bikes!
