The solar panels consist of thin film solar cells, which in our case are so called CIGS. These panels offer great perspective when it comes to applicability as they are flexible and produced more durable compared to regular silicium cells. CIGS solar panels currently have a lower efficiency than other solar panel types. However, a lot of research is being done to investigate the possibilities. The maximum power that the solar panels can generate is optimised by means of special equipment (MPPT’s). This way energy captured by the solar panels is efficiently converted into electrical energy.
On one hand the hull has to be as lightweight as possible, in order to reduce resistance. On the other hand, the hull has to strong enough in order to be able to withstand the loads. Therefore, the hull is made out of carbon fiber, which is a lightweight and strong material at the same time.
The energy captured by the solar panels is used to power an electric motor. Via a transmission system, the electric motor spins two propellors which have a contrary rotation direction. These propellors deliver the forward thrust of the boat.
The hydrofoils deliver the upward force that lifts the hull out of the water at a certain speed. This way it looks as if the boat is ‘flying’ above the water. As the boat ‘flies’, the air resistance grows, but the water resistance diminishes. This is a great advantage since the air resistance of our boat is way smaller than the water resistance. Hence, the energy captured by the solar panels can be used more effectively.
