Can you run a trolling motor off a solar panel?


You can not run a trolling motor off a solar panel because it does not provide enough power. A panel may provide 8 amps but the motor needs 40 amps.

You can utilize solar power in the maximum sectors you can ever imagine. So, you must also have a question that if the solar energy is so reliable than will it be able to replace the batteries of your trolling motors, here let’s find out that.

Since the revolution of modern technologies and even alternate technology is at its peak this is the reason why trolling motor technology has been able to progress so effectively into solar power usage. This kind of battery chargers are replacing even the AC models. But since this technology has been recently developed so there are many questions are there in the mind of people regarding its dependability and many more.


But the bitter fact is that it is still not possible to get a solar-powered trolling motor because the technology has not gone that far yet. This is all because the currently available solar panels are not able to put the constant power as required by the trolling motors these days. This is why it might take a little more time to establish a fully solar panel powered trolling motor. But still, it can be differently used up with the trolling motors. 

If you ever wish to use solar power on a trolling motor solely without the use of any kind of batteries then that’s quite not possible right now because it needs several high-end panels on the boat which might be inconvenient and even expensive as well. This is why people are preferring the use of batteries.

Also because you need to expose a solar panel to the unobstructed sunlight to deliver the maximum output which might not be possible in cloudy days and will eventually fail to take up the load.

Even we can take the assistance of some examples to explain the fact. The amperage requirement of a small 39lb thrust trolling motor draws 39 also at max thrust. But even a large solar panel of 12V and 150watt outputs around 8amps an hour in direct sunlight. So, in this way, a solar panel might not be able to meet that kind of draw. Although it can work properly on a pontoon boat with big solar panels installed in it but still not considered feasible by the customers.


Although this process is possible but still no one considers it feasible. But still, it is possible to recharge your trolling motor battery pack with a solar panel after it is used then you can do so but considering some of the limitations.

A solar panel with higher wattage is always very large in size so typically maximum people do not find that space in their marine vehicle and when it doesn’t seem to be feasible as it is going nothing but increasing the load. But still, it can be used since the maximum customers are using the battery group size of 27 to 31 for their trolling motor this means they need an additional backup after the battery being 50% used which means the solar panel has to assist with 50-65 amps if the battery gets low. 

Although maximum people do not care about the time their battery is getting recharged the fact in the favor is that the battery should get recharged in the quickest possible time because a long duration may result in the question within the battery. This also might be the reason why people even generally avoid the use of solar power chargers.

In this time when the environmental degradation is at the peak, the use of e-energy is being adopted and even the fuel use is being minimized so that the environment can be conserved. This is why even the caring anglers are stepping forward to reduce the carbon footprint.

Thus, the idea of using the solar panel with a trolling motor is really effective but still, the necessary development has not been done yet. Because using the heavy solar panel doesn’t seem to be quite feasible. And even in the case of some high power motors, the power supplied by the panel is not enough.
