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.

How to power an electric motor with a solar panel.

Another benefit of marine solar panel systems is the quietness of operation. You can run an engine from the outlets in a solar powered house or from the power generated by dedicated solar panels. The solar panels charge the battery when the motor is not running. However not all solar power configurations can power all engines.

Special schottky diode is used as it has minimal voltage loss going through it usually less than 0 2 v. And we used a suite of panels for testing including. So a 24v 140 watt solar panel at minimum up to a 24v 300 watt solar panel ideally is what would be needed. 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.

Alternatives to electrifying your boat like gasoline powered generators require purchasing fuel on an ongoing basis. In order to power an electric engine with solar power you must match the capacity of your solar power system with the requirements of the engine. Under direct sunlight the solar panel generates up to 6 volts of electricity with maximum current up to 270 ma. Unfortunately it s not possible to get a solar powered trolling motor.

Connect the two positive wires from the solar panels to the positive terminal of the dc motor. It s either that it is impossible to develop one or technology hasn t gone that far yet. So how do you get around this. Here is the electrical diagram of the solar panel connection to the motor.

Place the dc motor and solar panels outside in direct sunlight and look for the motor to start turning. Connect the two negative wires from the solar panels to the dc motor. This is the reason your motor is not working providing your solar panels can supply the rated motor current and voltage. 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.

You can simply twist the positive and negative leads from the solar panel to the motor. Diode protects the panel from negative current.
