Solar panels on a boat are primarily used to charge batteries and power the most important equipment on board. A well-dimensioned system can easily meet daily needs throughout the day.
Typical items that can be powered
- Lighting (LED) – low energy consumption and works all evening
- Refrigerator – one of the biggest consumers, but works well with solar panels
- Water pump – for fresh water and shower
- Charging of mobile, tablet and computer
- Navigation equipment – GPS, sonar, plotter
- Radio and safety systems
In larger installations, solar panels can also contribute to
- Operation of autopilot
- Inverter (230V) for smaller household appliances
- Support for electric motor (not as the sole power source, but as assistance)
In short: solar panels cover almost all daily electricity consumption on a leisure boat, allowing you to be self-sufficient without having to charge in port or run the engine.
