SolarStratos, a pioneering solar aviation project, is making waves in sustainable aerospace. At its heart is the HB-SXA, a manned solar-electric aircraft, poised to set an altitude record, symbolizing the feasibility and potential of solar-powered flight. This endeavor is not just about breaking records; it’s about advocating for solar energy as a vital component in combating climate change.

2023 brought new temperature records, highlighting the urgency for low-carbon solutions. SolarStratos is responding with HB-SXA’s planned record-setting flight, demonstrating the practicality of solar energy in aviation.

Key technical advancements in 2023 include the integration of a new telemetry system using UHF waves for better range (estimated up to 20km), enhancing HB-SXA’s communication capabilities. The solar-electric aircraft now features a more precise system, capable of streaming footage from two onboard Go-Pro cameras. New antenna and electronics for communication management have been added, with tests for these features eagerly anticipated by the team.

A notable change to the HB-SXA is its redesigned front. Accommodating eight batteries for the upcoming altitude record necessitated a larger air intake, resulting in a ‘fish-mouth’ shaped opening at the front, giving the aircraft a new, friendlier appearance.

SolarStratos’ commitment extends beyond aviation. The team, led by CEO Roland Loos and pilot-founder Raphaël Domjan, inaugurated a vocational training center for solar installers in Mboro, Senegal, emphasizing their dedication to global solar energy advocacy.
