Solar Impulse-2 Sets Solo Flight Record
Jul 13, 2015

Solar Powered aircraft Solar Impulse-2, on its first round-the-world solar flight, broke all distance and duration world records for solar aviation—90 hours, 6,800 km and counting.

Key Points

  • The Solar Impulse plane has broken the record for the longest non-stop solo flight without refuelling.

  • After leaving Nagoya, Japan, 76 hours into the journey, Solar Impulse-2 broke the record for the longest ever non-stop solo flight without refuelling.

  • After creating the record, Solar Impulse-2 was grounded in Hawaii because of battery damage.

  • The solar-powered vehicle overheated its electrical storage units during the historic, five-day crossing from Japan.

  • Solar Impulse-2, a single-seater aircraft made of carbon fiber has a 72 meter wingspan (larger than that of the Boeing 747-8I) for a weight of just 2,300 Kg, equivalent to that of a car.

  • The 17,000 solar cells built into the wing supply four electric motors (17.5 CV each) with renewable energy. 

  • During the day, the solar cells recharge lithium batteries weighing 633 Kg which allow the aircraft to fly at night.
