Polaris solar PV net news: Switzerland environmental explorers ‘ generation-Domijan (Raphael Domjan) on December 7, was released with only flew into Earth’s stratosphere’s first-ever manned solar aircraft project “Solar Stratos” (Figure 1, Figure 2).

Paul Domjan said, “Solar Stratos is to prove that even with current renewable energy technologies can also catch up with and even go beyond fossil fuels”. Domijan project solar sail alone “PlanetSolar” power boats sail project, and was completed in May 2012.
Solar Stratos is long and 8.5M wide (wings) 24.8M, 450kg two-seat single-engine propeller aircraft (Figure 3). In order to reduce weight, internal pressurization of the fuselage.

Solar Stratos’s goal is to fly to an altitude of 25,000 m (25km) in the stratosphere, where the temperature is-70 ℃, pressure on the ground 5%. So, need to wear a space suit when the crew aboard. Space suit’s energy provided by the Sun, which is the world’s first.
Equipped with a conversion efficiency of 22~24% Solar Panel
Fuselage set solar cell conversion efficiency of 22~24% products, with a total area of 22m2. 20kWh of lithium-ion batteries for electricity storage, for driving 32kW/2200rpm maximum output power of the motor.
Switzerland team of development experts at home and abroad, Germany ElektraSolar company develops Solar Stratos fuselage, the aircraft is equipped with a PV system Switzerland electronics and Microtechnology Centre (CSEM) developed.
In the SolarStratos project, Germany Aerospace Center (DLR), serving as co-pilot’s ThierryPlojoux, MichaelLopez-Alegria astronauts and a number of organizations, enterprises, experts, plans to support the project founder and pilot duomiyang.
First test flights will be conducted February 2017, including landing, medium altitude flight in summer 2017 and the first stratospheric flight will be launched in 2018. Roundtrip stratospheric flight is expected to take 5-6 hours.
In the long run, they plan to develop solar-powered flying drones to explore the stratosphere.
Switzerland has also been implemented in July 2016 only by the Sun flew aircraft for the first time successfully completed the voyage “shinin” (Solar Impulse) project.
Solar Stratos is unlike Sun power project, it is not clear whether personnel exchanges between the two projects. However, through the implementation of two projects in the future Switzerland has the potential to become solar aircraft and UAV technology development center, and the world’s attention.
