You can simply twist the positive and negative leads from the solar panel to the motor.
How to power an electric motor with a solar panel.
If you are using a group 27 to 31 battery you need a panel double the wattage of the 12 volt solar panels mentioned above.
The solar panels charge the battery when the motor is not running.
Unfortunately it s not possible to get a solar powered trolling motor.
Use either a capacitor or a small battery in the circuit to get the motor started then the solar panels keep the motor going.
Special schottky diode is used as it has minimal voltage loss going through it usually less than 0 2 v.
Although it s not an established fact it seems that the currently available trolling motors draw more power than today s solar panels are able to put out constantly.
Diode protects the panel from negative current.
Here is the electrical diagram of the solar panel connection to the motor.
So a 24v 140 watt solar panel at minimum up to a 24v 300 watt solar panel ideally is what would be needed.
Another benefit of marine solar panel systems is the quietness of operation.
And we used a suite of panels for testing including.
It s either that it is impossible to develop one or technology hasn t gone that far yet.
2 watt 6 volt 3 5 watt 6 volt x 2 paired in series to get 12v 6 watt 6 volt 9 watt 6 volt 9 watt 18 volt 17 watt 18 volt panel.
Connect the two negative wires from the solar panels to the dc motor.
Place the dc motor and solar panels outside in direct sunlight and look for the motor to start turning.
However not all solar power configurations can power all engines.
Switching to solar power can cut down on these purchases while protecting you against rising fuel costs.
You can run an engine from the outlets in a solar powered house or from the power generated by dedicated solar panels.
For 24v trolling motor batteries it becomes even more difficult to recharge the battery pack with a solar panel.
So how do you get around this.
Connect the two positive wires from the solar panels to the positive terminal of the dc motor.
Alternatives to electrifying your boat like gasoline powered generators require purchasing fuel on an ongoing basis.
