Best Marine Solar Panels

Boating is an ancient and time-honored skill, and for many, it’s also an enjoyable hobby. Getting out on the water can provide hours of relaxation and allow one to do everything from fish, to absorb the beauty of nature, to simply get away from work and home for a while.

But your boat will need power to help energize everything from cell phones to navigation equipment, cooking equipment, and lighting. Getting solar panels installed on your boat can be a simple and hands-off way to get the energy you need while on the water. Avoid the dangerous and noisy use of gas-powered generators for small items and get energy so long as the sun is out. 

Here is our list of the best marine solar panels and a break-down of the most notable features that they can offer you.

The 2 highly efficient 550 Watt Monochrystalline panels can provide 2200-2700 combined watt hours per day, depending on sunlight availability. This gives you commercial use-levels of power, and can keep you connected and safer on the water, for longer. 

The higher efficiency of these panels make them ideal for longer trips on the water, and can maximize the benefits of any good, sunny weather that comes your way. 

These panels are also ideally suited for powering marine batteries, and are durable and corrosion-resistant, meaning they can take a beating from wind and bad weather you may encounter on the water.
