MS Tûranor PlanetSolar was the first boat to circumnavigate the world powered exclusively using solar energy. This initial version of the solar boat is a 31-meter three-hull catamaran. Its deck has over 500 square meters of 18.8% efficient solar panels rated 93 kW. Panels charge 648 series and parallel connected lithium-ion batteries that produce 388 V and 2910 Ah. The batteries power two 10kW (maximum), 1000 rpm permanent magnet synchronous motors.
