Integral design

Born Electric

Right from the first line drawing, every aspect of our solar electric boats is purpose and integral designed and engineered for the highest efficiency for clean solar electric propulsion. Together with our partner Naval DC, the specialists for sustainable drive train systems, our engineering team has a unique skill set of electric naval architecture and electrical system integration. The result: Unprecedented performance and endurance.


Our electric propulsion systems are superior when it comes to power density and system weight. Averaging on 1kg/kW, our PMS electric drive train is the lightest and most powerful electric propulsion system in its class. Partnering with Naval DC means experience with ocean going solar electric naval architecture and PV and energy storage systems since 2007.

Premium Marine Lithium Battery Systems 

Marine grade lithium polymer batteries form the rock solid backbone of the system, including all safety features. Naval DC’s integrated systems feature modular, semi-custom lithium polymer batteries from 24V up to 800Vdc for high power applications. The cells used are from the leading lithium polymer cell manufacturer Kokam, which are well known for their exceptional quality, energy density and safe operation. Whether our batteries power the propulsion system through the night, or whether they need to supply the AC inverter for air conditioning on board, the system offers you all the power you need.


With only one moving part the electric system is basically maintenance free compared to any conventional fossil fuel powered motor. This allows for less headache about replacements of engines or dirty oils and results in a substantial amount of money saved at the end of every single year.

The total cost of ownership of the solar electric boats is approximately 20% of what a conventionally powered vessel costs over the years for operational costs (fuel), maintenance costs (consumables, service parts, etc.) and rebuild costs (investment for new engine after several hours of operation).

Technical support

For complete peace of mind our dedicated customer services team is always on standby. Offering remote technical support and advice for every Soel Yachts owner is one of our highest priorities. We are in this together.

Working with the latest software for updates and troubleshooting enables us to keep your modern boat on the highest standards. Whether you require warranty support, spare parts, system upgrades or a service visit anywhere in the world, our competent service team is not far away and pleased to help you further with what you need.

All of Soel Yachts sustainable electric boats are equipped with Naval DC’s smart technology for an integrated monitoring and alarm and control systems, the Naval UI.
The Naval UI alarm and monitoring interface for electric boats presents all relevant system data and offers remote monitoring and service support from Soel Yachts partner Naval DC.




All of our sustainable vessels are equipped with smart technology for an integrated monitoring, alarm & control system. The user interface can be viewed on a range of monitors or smart devices  — even your phone or tablet. It presents all relevant system data from your electric boat and enables us to offer remote monitoring and service support.

mobile power station



Our solar electric boats can even be used as  mobile power stations and provide AC inverter power for the mainland. The excessive solar energy can be used to feed back energy to the grid.


Most resorts use desalination systems to produce fresh water for laundry, showers and cleaning — an average energy consumption of 3 kWh for every m3 of water produced. Plug the SoelCat 12 into your grid and you can make the equivalent of 2000L fresh water with the harvested energy, per hour. The mobile power capabilities allow you to be fully energy autonomous without the need for any extra generator!
