Hey all, I had some stuff laying around and thought I would put together a solar powered boat. It was a fun project. I ran the motor directly off the panels so not really a lot of power but we did get it going! I made a video if you would like to see. Im hoping one day to get rid of the 2 stroke outboard!

Decent little vid!
Did you have the panels series or parallel wired?
Check the volts output in full sun?

Glad to see your back to making videos. I enjoy watching them all and was wondering when the next one will be.

I had them wired in series but I was using a assortment of bits of wire and wire nuts. I feel like I was never getting the full power. I need to build a better rack and wire it properly.

My bigger '12v' panels run 18ishv, Ive seen 36v with 2 in series. The higher the voltage the lighter the wire gauge you can use because the amps are lower compared to running 12v.
That motor is 78v? And how many amps? (if rated in watts, A x V = W). The closer you could get to the 'plate rate' the more efficient the motor will run. Probably not enough room on the boat for the optimum number of panels!
Think Id go for a min of 3x12v series batteries for 36v charged with 3-4 series panels. You could wire up the bats first to test run then figure out the array/scc required.

Thanks Brettny
It takes so much time to make a video! and YouTube makes it so difficult to find an audience. Im glad you liked it. If you can share it on social media I would appreciate it.
