Before we get started, you need to know a few vital things about solar energy. It can help you to understand the necessity of solar energy. Sun provides light during the daytime. Each particle of sunlight is known as a photon. Solar energy is the ultimate source and responsible for all weather systems and the Earth’s energy sources.

7 advantages of charging trolling motor batteries with solar

If you wish to recharge a 100-amp hour battery in a week, it will take a minimum of 100 watts of solar power. To produce the maximum-rated power of a solar panel, it takes straight sunshine on the surface of the dashboard. But a cloudy sky, improper mounting angle, and short winter days will reduce the actual solar panel output.

Why We Use Solar Power?

These days, peoples use solar power in numerous ways: heat for making hot water, heating buildings and cooking, recharging batteries for a trolling motor, boat, house, electric scooter, etc.

Can a Solar Panel Charge a Trolling Motor Battery?

Yes, it is possible. You need to attach a small 12v or 24v solar panel to your trolling motor battery pack.

You can also use a small 6-watt to 12-watt panel. In most situations, try to keep a fully charged battery box with you.

Are Solar-powered Battery Chargers Any Good?

The good news is solar battery chargers give a balanced stream of charging power. Even solar-powered battery chargers did not deliver the same amount as the standard electrically run chargers.

It will not overcharge your battery bit, which means these chargers will extend the lifespan.

Advantages of Using Solar Power for Charging Trolling Motor Batteries

Charging trolling motor batteries using solar panel power is the most efficient and eco-friendly ways nowadays. There are a lot of advantages of this technology. Not only has it protected nature also it is cost-effective and helps to reduce sound pollution. The advantages are-:

Clean Energy

Charging trolling motor batteries with solar is a clean energy source.  The battery charges through sunlight. So it does not have any impact on the ecosystem. What you need is a solar panel and sunlight. The panel converts the light into energy in a clean way without harming nature. This solar charging system does not make any harm to our waterways. It also protects our nature while you enjoy the scenic beauty.

Renewable Energy

The sun provides us the endless supply of clean energy which we capture and store through solar panel and use it for many purposes. If you use solar power to charge your trolling motor, you are using a clean energy source from the sun. You only need a solar panel to recharge batteries.


Using solar power to charge your batteries is a very cost-effective process. You have to invest set up the solar charging system for the first time, which will get a clean and renewable energy supply. You do not need to spend money on diesel or local electricity. This process saves your battery life long, so you do not need to buy new batteries every few months.

Low Maintenance Process

The solar charging system to charge your batteries through solar panels requires low maintenance. You only need to clean the panels and pointed them towards to sun. This process takes very little time as the parts are not so heavy and complicated.

No Fuel Operation

If you use a portable generator to run your trolling motor, you need to carry excess fuel while trolling out. It not only increases your trolling cost but also increases your boat weight. If you recharge your trolling motor batteries through solar, you do not need to carry those extra fuels with you.

Highly Portable System

Solar charging setup for trolling boat is a portable technology. When you troll the motor uses a large volume of electric power. So if you have this type of charging system on a boat, you can recharge your batteries while fishing or trolling.

With the portable solar power system, you can charge your batteries anytime, anywhere. The solar power system has its regulator does not need to worry about overcharging your batteries.

Sound Free System

When you go fishing, maintaining silence is very important. With the solar panel, you can recharge your batteries without making any noise. It is a completely sound free technology. Through, this system not only saves the ecosystem but also by making zero sound.

Types of Solar-Power Charger

You can get three types of solar-powered battery chargers for trolling motors.

Polycrystalline Panels – it is very efficient, durable, and produces large amounts of energy.

Mono-crystalline Chargers – comes with a characteristic black color and is made from a single crystal. It is quite expensive but offers better energy efficiency. It also able to give the best performs in low light conditions.

The third type is the thin film. To increase efficiency, its narrow design and in-built semi-conductors play a vital role. Unfortunately, their thin-film panels cannot absorb huge light.

Here Are Some Things You Need to Consider- 


Typically, you need to purchase a solar battery charger for your trolling motor, which comes with a 100-W panel.

Charge Controller

To avoid damages to your trolling motor batteries, pick a charger that comes with a charge controller.


Your charger should match the battery type because it is an important part.

Overcharge Protection

Solar battery chargers take a long time to charge batteries. If you somehow forget to discharge it, then it may cause overcharging. Look for a charger that automatically discharges the battery.

Battery Conditioning

Purchase a charger that can de-sulphate your battery. It can help to extend the lifecycle of batteries.

Can a 24 Volt Trolling System Benefit from Solar Charging for Batteries?

Yes, a 24 Volt Trolling System can greatly benefit from solar charging for batteries. By incorporating solar components for 24v trolling setup, you can reduce reliance on traditional charging methods and prolong the life of your batteries. This eco-friendly solution also allows for continuous power supply during extended fishing trips.

How Can I Use Solar Power to Enhance My Trolling Motor Experience?

When considering choosing the right trolling motor, incorporating solar power can significantly enhance your experience on the water. By harnessing the sun’s energy, you can extend your trolling motor’s battery life and reduce the need for frequent recharging. This sustainable solution allows for longer and more efficient fishing trips.

Can I Charge Trolling Motor Batteries with a Solar Panel of Any Size?

Yes, you can charge trolling motor batteries with a solar panel of any size. The size of solar panels will determine the charging capacity and time required. Smaller panels may take longer to charge, while larger panels can charge more quickly. It’s important to calculate the appropriate size for your specific needs.

Can Deep Cycle Battery Chargers Also Be Used for Solar Charging Trolling Motor Batteries?

Yes, deep cycle battery chargers can be used for solar charging trolling motor batteries. These battery chargers are designed to safely and efficiently charge deep cycle batteries, making them ideal for use with solar charging systems for trolling motor batteries.

Does the Solar Power Provide Enough Charge to Make a Difference?

If solar power provides enough charge to your unique trolling needs, I might say this is worth invest in a solar-powered battery charger.

Solar-powered chargers take a long time to charge your trolling motor batteries to get fully charged. If you have enough time in your hand, it is a great option to utilize your batteries.

Solar power can make a difference when it provides enough energy while using a charger that develops sunlight the right way.


At last, I can say solar is a perfect option for charging your trolling motor batteries. If you read this article carefully, you may be able to know many things about solar panels.

I tried my best to highlight some informative points, so some of your confusion about this topic gets cleared.
