An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. [ 1 ] While a significant majority of water vessels are powered by diesel engines , with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years.
The 31-metre boat is covered by 537 m 2 [6] of solar panels rated at 93 kWp, [7] 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. [8] The boat's shape allows it to reach speeds of up to 10 knots (19 km/h). [1]
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 ...
The 27-metre-long and 7-metre-wide boat is covered by 125 square metres (1,350 sq ft) of solar panels rated at 25 kW, which in turn connect to two electric motors of 20 kW, one in each hull. [3] There are 1500 kg of lithium-ion batteries in the ship's two hulls with a total capacity of 80 kWh.
The largest solar power system flown in space is the electrical system of the International Space Station. To increase the power generated per kilogram, typical spacecraft solar panels use high-cost, high-efficiency, and close-packed rectangular multi-junction solar cells made of gallium arsenide (GaAs) and other semiconductor materials.

A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
