But i am still not sold on how practical they are yet. What about long patches of rainy days with no sun? Have to watch more videos.

I have two 100 Watt panels (53x106 centimeter each) and I only get 30 kilometers extra on a good day. Maybe with double the panels through a desert you could have e-assist whole time? Most efficient would be charge during the day and ride at night. But who does that? If you want panels and batteries in Europe then try get in touch with people of the Sun Trip. www.thesuntrip.com/ Maybe direct order from China and have it shipped to an address? But keep in mind that roads and trails in Europe aren't wide enough for a football field of solar panels. On a bike maybe one as a roof, and two on a trailer? Problem is extra weight and wind drag. So it is questionable if it makes you faster. Just e-assist is probably fastest. Reason why I have solar panels is because I like the roof! And since I have a roof then why not solar? Hopefully one day I can be independent from wall charging. That would be great. But for now, in Europe, nope.

Making the panels into an airfoil that generates lift would actually _increase_ drag, and wouldn't be all that useful; bicycles have very low rolling resistance compared to their air resistance, so getting lift at the cost of drag wouldn't be a good trade. As for motors that produce more than they use, they're gonna have to figure out a workaround for that pesky "it's impossible" thing before they make that project public.

@xameslyons5 жыл бұрын
can you talk some about how you panel battery interface works. in other words how are you getting the solar energy into you drive system?
@TheRamblingShepherd5 жыл бұрын
Certainly. The battery interface is about as simple as it could be; There's a Y-harness that connects the battery, the 3-phase speed controller, and the solar panels in parallel. The battery has a built-in management system that balances the cells. This system is simple but far from optimal. The panels each run at an optimal 18v, so 72v for the whole series. The panels produce about 5.5 amps in nominal test conditions, which would yield the advertised 400 watts. However, when my battery is plugged in at its ~48v, it's thirsty enough to draw all the energy the panels can produce and then some, so the panel voltage sags to that same ~48v level. They can't magically produce more current, though, so they're only putting out 5.5A x 48v = 266 watts, even in perfect conditions. Better than a quarter of my energy is being lost to a voltage mismatch. As such, I do most of my riding with the battery unplugged. The power computer runs the speed controller quite happily straight from the panels. If I manage my throttle correctly, I can keep the panels in their happy 72v band and extract the maximum amount of energy (only about 350 watts at solar noon on the day of the video; conditions are far from optimal at this time of year). When getting into the hills or through shady stretches of road, however, I plug the battery back in to the circuit to supplement the panels. What I need to solve the voltage mismatch problem is a maximum power point tracking charge controller; this would allow me to get 100% of the energy that the conditions allow from the panels even with my 48v battery. Good ones are a bit pricey, however, and I haven't got that budgeted at the moment.

5:40 you said you unhooking the battery, but your final analysis said you used the battery??? so you have 70v panels dumping into a 48v battery? does not that mess up your battery?
@TheRamblingShepherd3 жыл бұрын
Excellent questions! I unhooked the battery for most of the trip, but connected it back up for the hilly sections, since the panels didn't provide enough power on their own to climb the hils. As for whether it could mess up my battery, think of it like filling a car tire from an air compressor; The air compressor may have 8 bar of pressure in its tank, while your car tire may have an ideal pressure of 2 bar. Connecting your tire to the compressor doesn't make it explode immediately, because air can only flow into it slowly. If you kept filling your tire once it had reached 2 bar, it would be dangerous, but until then, you're fine. Likewise, the panels can't immediately raise the battery voltage to 72; that would take a long time, and on top of that I'm draining the battery as I ride and watching to make sure it doesn't overcharge. Leaving it hooked up for a long time without a regulator WOULD be very dangerous, but as is, it's quite safe.

It's not overly safe riding a fully loaded touring bike and pulling a trailer without a large sail attached.
