The 31-metre boat is covered by 537 m 2 [7] of solar panels rated at 93 kWp, [8] which in turn connect to two electric motors, one in each hull. [2] There are 8.5 tons of lithium-ion batteries in the ship's two hulls. [9] The boat's shape allows it to reach speeds of up to 10 knots (19 km/h). [1]
A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
List of solar-powered boats is a list of boats powered by the sun, typically solar panels providing electrical power to motors. Aditya, India's First Solar Ferry, [2] 75 passenger boat is operating in Vaikom, Kerala, India. [3] [4] Alstersonne is a passenger ferry for 100 persons on the river Alster in Hamburg, Germany. As of year 2000 it was ...

Solar powered boats started to become known around 1985 and in 1995 the first commercial solar passenger boats appeared. [41] Solar powered boats have been used successfully at sea. The first crossing of the Atlantic Ocean was achieved in the winter of 2006/2007 by the solar catamaran Sun21. [42] [43] (see also List of solar-powered boats)
The yacht's hull has a tumblehome shape and is equipped with foils, which were upgraded in 2016 and again in 2020. The boat was commissioned for the Gitana Sailing Team founded by French banker Benjamin de Rothschild. Her first skipper was Sébastien Josse who was later replaced by Boris Herrmann. The yacht does not use any fossil fuel for power.
Thunberg sailed on board the Malizia II, a 18 m (60 ft) racing yacht that was built for round-the-world challenges. Solar panels and underwater turbines generate the power for lighting and communication. Designed for speed rather than luxury, conditions range from basic to difficult, for example the boat has no kitchen, toilet, or shower. [9]
