Solar panels electric motor

[Kerry]

I think the feasability of actually putting panels on a tinnie has already been eliminated. But if it's a case of being out and about for a few days then panels "might" work for recharging on a rotation basis. But it's also already been said that the cost might/will be a bit scarey.

If you get over this inhibition about this spreadsheet and plug the numbers in you'll probably have a reasonable answer but what makes me think you don't really want to do that.

Cheers, Kerry.

I'll check it out. No worries.

Well Kerry,
I had a look at the charts and I got
40w = 16.9volts x 2.34amps. Isn't that close enough to what I said using me noggin instead of looking at a chart. I was .01 out on the Voltage and that was just a guess and .01 out on the amps as I didn't round up. What are you trying to tell me mate. ??? Admittedly the dimensions I gave were slightly out on the larger side mind you and that makes it even less feasable.
Cheers Luke

So how many panels did it think you might need to re-charge your 105a/h battery in a useable time. Might be a few I'd imagine ???

Cheers, Kerry.

Yeh I think this one is a lost cause. I'd have to build a roof on the tinny.
