Whether you are fishing, sailing, or just cruising the lake, all you need is a reliable solar boat battery charger to make the entire experience more memorable. It is helpful for boats out in the sun without access to shore power. Solar chargers for boats range from small trickle chargers for some lights or trolling motors up to thousands of watts that can charge most of the boat appliances.
From the smallest fishing boat to the largest yacht, solar charging offers peace of mind and convenience. If you want to choose a clean power source for your boat, Jackery offers many portable marine battery chargers. The compact design of the solar panels and portable power stations ensures the boat electronics and battery remain charged throughout the boating trip.
How Solar Battery Charger for Boat Works?
A solar charger for a boat battery typically consists of three parts: solar panels, an MPPT charge controller, and a battery backup (optional). The solar panels collect the sunlight and generate electricity. However, the electricity produced by the solar panels is not conditioned for the boat batteries and could damage them if connected directly.
Therefore, the solar panels have to be connected to an MPPT charge controller to regulate the current and voltage flowing to the boat batteries. The regulated electricity is then transferred to the boat battery for charging. Jackery Solar Generators work by sunlight into electricity that can charge most of the boat electronics, including navigation lights, portable fans, etc.
The Jackery SolarSaga 100 Prime Solar Panels work as one of the best solar panel battery chargers. They can be installed on the boat to collect solar energy and produce electricity suitable for charging the boat or marine battery. All you need to do is connect the solar panels to the boat battery through the MPPT charge controller.
What Size Solar Charger for a Boat?
Determining the size of a solar charger for a boat depends on the daily power usage in watt-hours. You can calculate the power consumption by listing all the electrical devices and how long they are used. The size of the marine solar battery charger will also depend on the boat's battery capacity, sunlight exposure, and charger efficiency. Here is a table that gives you an estimate of what size solar charger is required for different sizes of boats:
|
Boat Size |
Average Daily Wattage Consumption (Wh) |
Solar Generator Size (Watts) |
|
Small (up to 20ft) |
300Wh - 600Wh |
250W - 500W |
|
Medium (21ft to 35ft) |
600Wh - 1200Wh |
500W - 1000W |
|
Large (36ft to 50ft) |
1200Wh - 2400Wh |
1000W - 2000W |
|
Very Large (over 50ft) |
2400Wh+ |
2000W+ |
If you're looking for an alternative solution that can charge most of the boat electronics, consider solar generators. Many portable solar-powered generators are easy to set up and use. The right size of the Jackery Solar Generators for your marine or boat depends on the boat's battery capacity and the number of hours you will receive sunlight.

Maintenance Tips:
- Do not use the portable power station on an extremely hot day, in direct sunlight, or in a car to prevent overheating.
- You should store the power station in a dry and cool place. It should not be in contact with corrosive substances, fire, or heat sources.
Charging Tips:
- You should use the power stations in a well-ventilated area and avoid restricting ventilation in any way.
- Avoid using products through damaged cords or damaged output cables to prevent electric shock.
- You should not expose the power stations to fire or high temperatures that can lead to fire and explosion.
- It is highly recommended that the power station be operated and recharged every three months to keep it active.

FAQs
Do solar battery chargers work for boats?
Yes, solar battery chargers can work for boats. They can provide power when you are out on the water all day without access to shore power. They are eco-friendly, maintenance-free, and cost-saving charging solutions for sustainable boating.
Can you charge a marine battery with a solar panel?
Yes, you can charge a marine or boat battery with solar panels. However, the choice of solar panel will depend on the boat's battery capacity. Jackery SolarSaga 100 Prime Solar Panels can be installed on the boat to charge the boat battery with the help of an MPPT charge controller.
How long does a 100-watt solar panel take to charge a marine battery?
The time required to charge the marine battery with a 100-watt foldable solar panel will depend on the boat's battery capacity and the amount of sunlight available. Let's assume you are charging the boat's battery capacity of 1200Wh with the Jackery SolarSaga 100 Prime Solar Panels.
If the solar panels receive 5 hours of sunlight, the electricity produced will be 100W*5H = 500Wh per day. However, the system is not 100% efficient, and there will be some power loss. If the system is 85% efficient, the electricity produced will be 425Wh per day.
Here is the basic formula to calculate the time taken to charge the marine battery:
Time Taken = Boat Battery Capacity ÷ Electricity Generated by Solar Panels = 1200Wh ÷ 425Wh per day = 2.8 days
Is it OK to leave a boat battery charger on all the time?
Yes, it is generally OK to always leave the boat battery charger on, assuming it is a smart charger or battery maintainer designed to switch to a maintenance charge once the boat battery is fully charged.
Conclusion
Solar boat battery chargers have a high upfront cost, but they will start paying for themselves and save you money. They are eco-friendly, work quietly, and eliminate the need to refuel a generator. If you have the right solar charger for boats, you don't have to worry about running out of gas or not having enough power for boat appliances.
