A question on your other roof top panels . Do you have a problem with hooking up different wattage panels ? Some say it is ok 👌. Others say it doesn't work .
The main thing with mixing up different brand panels together is finding panels which are really similar to each other. I highly recommend researching a few videos which explain the main things that you should be looking for. As an example, the voltage will drop down to the lowest panel voltage in the series (if I remember correctly). So if you have one panel that's 170 watts at 24 volts and another panel at 180 Watts 23 volts they should work quite well together but if you have another panel that's 120 watts 22 volts and 200 Watts 35 volts these two panels won't work efficiently together. Hope that's helpful, again definitely worth researching further.
Hi, I was wondering if you still had panel in test what this would generate vertical. I'm thinking of adding x3 of these to each of my garage door and can't anything about vertical panel efficiency. Thank you!
I would say vertical/horizontal it wouldn't make much of a difference it's more to do with the angle of the panel facing the sun and making sure that the shadow lines up facing behind the solar panel when facing the sun
Surprisingly at noon it barely reaches the cells and if on the aero bars on the front, there is barely any chance of shading. At dawn and dusk the sun isn't really high enough yet anyways and the position changes a lot while riding on windy roads.
So I just received something in the mail that allows me to convert the 18-20v from the solar panel into 36-42v needed to charge the my ebike battery via a small MPPT charge controller. In theory this should work via my brief testing with it so far. Now it's time for a test ride!
I read your comment again I think I understand now that you are wondering if you can use MC4 connectors on a cable to a DC plug directly into your power station? Solar generators have mppt charge controllers inside of them already so yes you can do this.
Not exactly, no. But almost all Solar Generators or Portable Power stations can charge via power directly coming from the solar panels. Because they have built in MPPT charge controller inside of them.
@@TheOneGoodRoad just realize when you do that even if your converter was 100% efficient and its not you will lose a third or so of the wattage. So if your getting 90 watts x 3 270 watts total at 20 ish volts and you go to 36 your going to get 180 watts is perfect scenario cool panel direct sunlight . Honestly my math is not precise because 20 is not a third of 36 and you want to be higher than 36 to charge a 36 volt battery and there's no way to know the efficiency of what you have so honestly best case your solar set up would actually charge a 36 volt battery at a rate of around the 125 watt range. So assuming that e bike has the simplest gear hub type 250 watt motor you're looking at it taking twice as long to charge than ride. BUT If your bike has a multi mode controller and you put it in its lowest power and speed mode on level ground you maybe just might be able to run infinitely when the suns up.

When you are sitting on the bike you are probably casting a shadow on the panel, maybe put it further away from the saddel?

@@TheOneGoodRoad kwh per day generated approx?
Can you make more videos on your solar bike?
Yeah I'm working on a bunch of videos at the moment for the channel but the solar bike project will be up soon! 😁
3D print a cover for the wire cover.
Did you use a standard mc4 to dc adapter and connected that to the powerstation? Not sure if it.would work

@@TheOneGoodRoadwait the eco worthy has a mpp inside already? So i can just use the "merger adapter" taking two mc4s and outputting it as dc?
Not exactly, no. But almost all Solar Generators or Portable Power stations can charge via power directly coming from the solar panels. Because they have built in MPPT charge controller inside of them.
