Best solar panels for boats

Which are the best solar panels for boats ? Sailing without engine noise and wasting fuel seemed crazy a few years ago. Today, it would be even more absurd to spend thousands of dollars on gasoline when we can take advantage of the sun’s energy at a much lower cost.

But, do all solar panels work on a boat at sea? We researched and selected solar panels that work in all weather conditions. Listed here are the best solar technologies to take on board.

Uses of solar energy on the boat

Powering the boat’s engine. A solar panel of the right size can absorb the amount of solar energy your engine needs to run.

Power various devices and accessories with solar energy. Carry a refrigerator, chargers, radios, or televisions onboard, without the expense of fuel.

Power the boat’s lighting with the sun’s energy. It reduces fuel consumption. You won’t have to use a noisy conventional generator to turn on the lights at night either.

Installation of solar panels on the ship

Fixed panels

If the deck surface is flat, install solar panels with an aluminum frame and safety glass. Take advantage of the deck of the boat or the Bimini if your ship is thin.

On the other hand, if the surface of your boat is curved, use flexible or semi-flexible solar panels. These do not have a rigid frame. Attach the flexible panel to the roof with polyurethane adhesive. If you want to install and uninstall it easily and turn it into a temporary installation, use the flexible device, taking advantage of the eyelets in each of its four corners.

Rotating panels

To optimize the reception of photovoltaic energy, the panels must be perpendicular to the sun’s rays. Therefore, it is convenient to use systems that allow the rotation of the panels and improve performance. Fixed panels can reduce functionality. If an area of the solar panel receives only shadow, it will stop working, even if it has half of its structure in the shadow. Use brackets above the stern or radar arch to locate the panels.

The quality of the cable is critical in the installation. It must be an electrical cable of a cross-section capable of withstanding the corrosion of the marine environment. Although not inexpensive, it will be more durable than conventional cable.

Advantages of using solar panels for boats

Today, the use of solar energy does not seem surprising because, thanks to technical progress, it has become commonplace and familiar. Solar panels are used in everyday life: in industries and businesses, allowing significant savings with alternative energy supply.

The first reason to take advantage of solar energy in shipping is the significant fuel savings. Solar energy is much cheaper to produce than electricity generated by a fuel generator.

The second reason is noise pollution. It is a critical issue for a quiet life: reduce sound levels while staying at sea. Since a regular generator often emits sound while operating the boat.

In contrast, solar panels for marine use are silent. Marine solar panels do the job of generating electricity simply and efficiently. At the same time, they save you from excessive noise pollution.

The additional advantage of having solar panels on your boat is that you can charge your boat’s battery without being on top. Therefore, one can secure a ship at sea and engage in other activities such as diving or fishing. Keeping photovoltaic systems connected to the boat means that you can reliably release some electrical pressure even when diving.
