Solar Trolling motor

Recommended Posts

A question for all you engineer types...

I'm thinking of installing a trolling motor on my kayak. Probably 12v but possibly 24v. I'd like to charge the battery/batteries with solar as I'm running it or at anchor fishing.

Is this possible? If so how big of a solar panel will I need?

Yeah....If I had the money for a torqueedo I wouldn't be fishing from a kayak

Any engineers that understand what I'm trying to "build"?

I apologize - you didn't provide that info in OP. As far as engineer - no only HS but do have  7 electro / mechanical patent aps with my name on them.

Here's an instruction link that might help

Did look for trolling motors several hundred $ - on Ali Express

Probably not able to while on water. It is a small car /  motorcycle battery after all.

Thanks guys. I have no problem finding a trolling motor. Interested in installing a solar panel to power the unit and charge the battery.

How big a panel do I need?

Solar panel will depend of the battery and how many amp the trolling motor use

 

Will you use the panel only or charge the battery with a normal 220v battery charger before you go fishing ?

Too big probably if you want 1 for 1 - run time vs charge time

The smallest motor I illustrated takes 318 w at full power - if you take it slow and stop for long periods of time can get by with a much smaller panel

Hard to say what your power consumption will be. Example - not  sarcastic

Run motor 1 hour at 318 w/ hr - would need almost 16  hours to fully re-charge battery using 20 watt solar panel (if it was 100% efficient)

Here is some info to start - I know US but tech data is valid
