Best Marine Solar Panels

Boating is an ancient and time-honored skill. It’s also an enjoyable hobby. Getting on the water can provide hours of relaxation and allow one to do everything, like fishing, sightseeing, or simply getting away from work and home for a while.

However, any boat will need the power to energize everything from cell phones to navigation equipment. Just imagine the dread of sailing dead in the water with nothing to charge your phone or use the navigation. You also need to power 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. In that way, you can lessen your dependence on smelly, noisy, and dangerous gas-powered generators. 

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

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

The high efficiency of these panels makes 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. They are durable and corrosion-resistant, meaning they can take a beating from wind and bad weather you may encounter on the water.
