AALTO HAPS Ltd. (UK) is a major company in the solar-powered drone market, focused on the Zephyr HAPS, a solar-powered stratospheric UAV designed for long-duration operations. Zephyr has recorded more than 67 continuous days of stratospheric flight and uses solar arrays and lightweight batteries for power. AALTO is developing applications in Communication Relay and Earth Observation and, in March 2026, signed an agreement with Telkomsel to support future Zephyr operations in Indonesia.
Skydweller Aero Inc. (US) develops large solar-powered UAVs for long-endurance UAV, persistent surveillance, communication relay, and Earth observation applications. In July 2025, the company completed a multi-day flight campaign with the U.S. Naval Air Warfare Center Aircraft Division, including more than 74 hours of continuous solar-powered flight. In January 2026, Skydweller, Nokia Federal Solutions, and Tangram Flex received a U.S. Air Force contract to demonstrate an airborne private network using the solar-powered aircraft.
AeroVironment, Inc. (US) has a broader unmanned systems portfolio and is also developing Solar HAPS – Sunglider for long-duration airborne operations. The platform is positioned under AeroVironment's Space Systems and Resilient Communications capabilities, linking solar-powered flight with communication applications. AeroVironment's fiscal year 2026 revenue reached USD 1.98 billion, which helps reflect its larger overall unmanned systems business along with its ability to support development of advanced UAV platforms.
