Solar battery charger for boat


Our 5 highly recommended best solar battery charger for boat accessories and vital boating functions. But before we dive in, why do boaters need solar battery chargers while they are out on the water?

Solar battery chargers

These solar battery chargers for boating are designed to recharge the batteries of your boat during certain circumstances.

An example of one such circumstance, would be if you were out on the water and had some equipment like a fish finder or GPS that ran off of battery power and your boat’s engine was not running (more on this later).

Solar battery charger: crucial must have!

This solar battery charger is an absolutely vital piece of equipment for you to have on your boat if you plan to do any type of boating that will require you use power tools or other accessories off of battery.

This is because the deep cycle marine batteries that are installed in most boats, typically take anywhere from 8-12 hours to fully charge when they are being fed a steady supply of energy from the boat’s engine.

In other words, if you will be out on a larger body of water for an extended period of time and want to use some boating accessories that require a power source, you had better have a solar battery charger or another means of charging your boat battery.

Solar battery chargers: sizing up your options

If you are looking to buy a solar battery charger, there are only two type of solar panels that boaters should be concerned with.

These types of panels include monocrystalline and polycrystalline. Polycrystalline solar panels are typically cheaper than monocrystalize ones but they also have lower performance ratings (wattage).

Monocrystaline solar panels are said to have less of a performance drop when the intensity of the light hits them drops.

As such, monocrystaline cells can maintain a higher output at lower light conditions. However, polycrystalline panels are less expensive and also lighter in weight providing more options for mounting.

Mounting options: what to look for

If you are looking for a solar battery charger, look for one that comes with stainless steel mounting hardware.

This is because the metals used in cheaper mounting brackets will eventually rust and need replacement.

Remember if you plan on keeping your solar battery charger mounted on your boat during long periods of non-use, you should take it down from its mount and store it dry to prevent corrosion.

Also be sure to select a solar panel that has a framing system that best fits within your budget and easy of installation requirements. A few quick tips: If you know that you will not be able to charge your boat’s battery via means other than an engine powered generator, do not bother with a solar battery charger.

If you have a couple of 12V marine batteries, it is best to buy a solar battery charger that has one or two panels as opposed to buying a larger panel with more wattage capacity if your boat requires multiple batteries.

Finally, find out the weight limits on any mounting hardware that comes included with your solar battery charger and keep those limits in mind when installing your system.

By doing so, you can ensure that your boat’s deck structures won’t be compromised by the added weight of the solar panels during boating trips.

In some cases this might necessitate purchasing new mounting hardware from an outside source (i.e., McMaster-Carr).
