Boat power generation

The production of energy on a boat is an important issue for navigation and the operation of the various systems on board. To produce your own electricity, 3 sources of energy are available: water, wind and sun. The most common means of generating energy on board are wind turbines(Silentwind or ATMB), solar panels and hydrogenerators(Watt & Sea). This electricity can then be used to power the boat's various systems and electrical installations, such as lights, navigation lights and electronic devices. These energy sources require electrical installations consisting of cable sections, batteries and switchboards.

Since the batteries on board our boats have a limited autonomy, it is essential to be able to generate electricity on board in order to never run out of power for your instrumentation and navigation equipment.

This is not only a question of comfort, but above all, of safety. Compass, VHF, GPS, autopilot and all the other essential navigation equipment are powered by electricity. To prevent this power supply from running out, we offer you in these sections energy production sources as well as all their accessories. 

You can find here the alternative to the engine of your boat to supply it with electricity: wind turbine, hydrogenerator, generator and solar panel, but also a section dedicated to the alternator. You can then use the windwater flow or the sun for recharge your battery and produce your own electricity on board.


Several alternatives are available to you, allowing you topower and recharge the batteries without running the engine, some of which use only natural elements to generate power. But between the wind turbine, the hydrogenerator and the solar panels, which solution is the most adapted to your needs?

  • The hydro-generator has the particularity to work with the movement of the boat. As long as the sailboat moves forward, the hydrogenerator generates.
  • The wind turbine will be more efficient when anchored. Indeed, the relative wind created by the movement of the boat disturbs its operation.
  • Solar panels, on the other hand, can work when there is sufficient solar radiation, but do not generate energy when it is cloudy.

As you can see, it is safer to install several electrical production devices on board, some producing electricity at anchor and others while sailing.

Operation of the on-board power generation facilities

Wind energy is produced through the use of wind turbines installed on the boat. These turbines are able to capture the energy of the wind and convert it into electricity through a generator. This electricity can then be used to power the various systems on the boat, such as lights, electronics and engines.

Solar energy is produced through the use of solar panels installed on the boat. These panels are able to capture the sun's energy and convert it into electricity using photovoltaic cells. This electricity can also be used to power the electrical systems, recharge the batteries...

Thehydro generator, finally, allows to produce electricity thanks to thekinetic energy of the water. It is a device installed in a propeller at the back of the boat, which is able to convert the energy produced by the movement of water into electricity. 

By using these three means to produce energy on board, boats can operate in a sustainable and environmentally friendly way. This reduces dependence on fossil fuels and contributes to the protection of the ocean and the species that live there.
