I found this stuff 15.4V Operating Power, Operating Current .3 Amps, 5 Watts. If this was made into a skin on a Motorcycle would it help the range of the thing especially when parked? What kind of power is this? If figure it would work better than laying a big flat solar panel on the back of the bike, i could shape the stuff around the tail section of the bike and on the opposite side of the Kick stand. No real bike yet but will build a bike with bodywork race bike style.
Thanks

well, whats the area of a piece with those specs? that would be the question needed. .3A is NOTHING when it comes to charging/running.
5W is very very low. You’d need something a bit higher (200w would charge really slow, 500 -1000 would be best)
a Piece 5" X 6" gets you 6 volts 100 amps .6 watts. SO if you can squeeze 20 of the things on one side you get 120 volts and the other calculations that I am sure are not just multipliers. Maybe squeeze off 2 or 3 more on the gas tank 1 or 2 more on the tail of the bike (assuming a one seater). max out one side of the bike to say 25 panels. will it do anything? BTW cost $26.00 per panel total $650 bucks will get you? sounds like maybe an extra mile or so…
there has to be something… can you at least recommend a setup that will get me a 50 mile charge at 55 mph?

There’s a company in Australia that has developed a high power density solar cell but it’s not for sale yet. A single 2"x3" cell supplies 550 Watts, whereas the average 2ftx4ft solar panel yields only 80 Watts. I’m not 100% positive but this 550 Watt figure may require use of a parabolic reflector to intensify the solar energy hitting the cell, as that’s how their test system at an Aboriginal tribe was set up.
The high density cell would really change the face of solar power generation though.

you mean 100 milli-amps… not amps. If its 100A at 6V thats 600W, and if its only 25 bucks a panel, I want 100 of them 
and no, 25 of those won’t produce enough to go very far at all.
Most motorcycles take above 125Wh to cruise. if you had 25 of those, you’re putting them in series, thats 120V, but still only .6A and maybe 72W… it would take DAYS maybe even longer, to charge up the batteries if they were discharged. Its just not doable, you have losses in the wires/connections and the charger, so remove another 40% from inefficiency. MAYBE 45W. Thats not much. It would likely only slow you down with the extra weight (even though you’re light, a few lbs can negate any gains)
Now, if you have a small solar grid, of 150W panels, maybe 4 of them, thats 600W. You can definitely use that. Throw an inverter on it and plug your bike right in. You need something in the tripple digits of watts for it to be worth spending 600 on. I’d rather spend my money on lighter batteries, save up for lithium, buy a more efficient motor or controller, or buy carbon fiber parts for the bike so its lighter.
if you want to spend 600+ dollars, go ahead, but It likely won’t generate any usable energy, and definitely not enough to go very far.
Thank You… that was a lot more optimistic than some of your other posts Even though this is a relativly new thing it seems that everyone has already thought of everything?
Ok, so originally the idea was to draw some more range out of the bike so when its parked where ever I am some more power heads to the bats rather than nothing at all. But for the money i guess I am looking at your typical high po after market parts, like CF wheels, and various other bits.
Liion bats I swear i saw somewhere that the power needed to run the bike at the current cost of batteries puts the bat cost at $9000 ? That is way too much. Can you add Liion bats as you go to a Lead Acid system?
10 times the money doubles the range? I assume that there is a weight save as well?
Ok I’m going off to read more… If anyone knows of a Liter Bike in the VA area with a bad motor cheap let me know.
Thanks for putting up with me

haha, I’ve been working on it a little
But yeah, people talk about adding generators, alternators, wind turbines and solar to their car. You need something that is light and can get you a good power to weight ratio. Solar is up and coming, just not there yet…at least not cheaply.

If its parked, you’d be better off trying to ask work to install a charge area… or drive to places with outdoor power. The NEXT best thing would be to lighten that frame up, and take everything off you don’t need.

You wouldn’t be able to fit in $9000 worth of bats that easily. I’d estimate if you wanted 40-50 miles, at 150Wh/mile (actually high), that puts you around 6-7000Wh, and you’d need around 22 cells (~72V). that would give you 7040Wh. 22 cells, at 200 a pop, is 4400, much more affordable. Plus BMS, plus charger. Not too bad actually. I’m going to see if I can’t source some 50Ah batteries, maybe even 40Ah. Just depends. I’ve seen 20Ah bats for 33 a piece.

Yes, lifepo is roughly 1/3 the weight of lead for more Ah. But also, lead is more stiff and can supply MORE hard current under acceleration. it seems that right now, lifepo isn’t giving people the current output they need for larger cars, but for Motorcycles, its fine.

I did the same thing when I started researching 8 months ago… now I’m almost done with the bike. Its easiest to get a bike and plan the system around it in my opinion. That way you chose a motor that fits, a controller to match the motor, and what you’re left with is a shell with enough space for batteries. Remember, make Lead fit right now, get her going, and upgrade to lifepo. You shouldn’t mix battery types, but you can get a small pack (48V) and run, then upgrade to 72V and beyond.

Well that dude in Ironman had a power source on his chest that could power a giant iron suit to 85 thousand feet on rockets how about we find that power source

again im a moron right now do not have any idea what ur talking about will soon enough and will refer back.

ok will work out the bike hoping to find something more modern generally the newer the lighter.

Look up Lifan in your area… its a bike manufacturer… and a guy recently built one up… got the bike brand new for 650 without engine… maybe the dealer will cut you a deal.
Hi,
Lifans are Chinese motorcycles typically found on E-bay. You can Also search for Zongshen and “Chinese motorcycle”.
Because of the road conditions in China are so poor, (Yes I have been there) motorcycles in China rarely ever see 50 MPH. Also any bike over 200cc requires a special license, so the dense traffic of bicycles and 125cc bikes limits the speed there too.
When Americans get these inexpensive bikes we try to take them on the highway and burn the valves or blow the engine. So you might very well find a frame with a blown engine real cheap.
One thing to keep in mind if you leave lead acid batteries, for one of the exotic formulas, is unexpected results if abused or damaged. Here are some interesting videos of Lithium Polymer batteries exploding.

The “liposack” is supposed to contain the heat and flames so your home or car doesn’t go up in flames too. I’m not too convinced it works.
