Solar-Powered UAV Market Size

The global solar-powered UAV market was valued at USD 356.3 million in 2024 and is estimated to grow at a CAGR of 9.2% from 2025 to 2034.

The global focus on sustainability is a primary driver for solar-powered UAV adoption. As concerns about carbon emissions and environmental impact increase, industries are seeking eco-friendly alternatives to traditional fuel-powered vehicles. Solar-powered UAVs offer a cleaner solution by reducing fossil fuel dependence, helping companies and governments meet sustainability targets.

For instance, In October 2024, AeroVironment (AV) successfully tested its upgraded solar-powered aircraft, Horus A, marking a major advancement in high-altitude long-endurance (HALE) flight. Developed in partnership with SoftBank, this latest version of the Sunglider platform enhances stratospheric payload capabilities, positioning it for key government and commercial applications such as surveillance and telecommunications.

Sectors such as agriculture, surveillance, and telecommunications require long-duration flights, which solar UAVs can provide without frequent recharging or fuel consumption. This demand for sustainable, cost-efficient, and environmentally friendly technologies positions solar-powered UAVs as a viable solution in the evolving drone market.

Advancements in solar panel technology have improved the efficiency and energy conversion rates of solar cells, enhancing their suitability for UAV applications. Lightweight, high-efficiency solar panels now generate more power from the same surface area, enabling UAVs to fly for extended periods without large batteries. For instance, A 4-gram solar-powered drone, the smallest of its kind, has successfully flown using an electrostatic motor and tiny solar panels generating high voltages. While the hummingbird-sized prototype flew for just an hour, its developers believe this technology could lead to insect-sized drones capable of staying airborne indefinitely.

These innovations have made solar-powered drones more practical for long-duration missions including surveillance, environmental monitoring, and remote sensing. As solar cells become more efficient and cost-effective, they will continue to drive the growth of the market, offering enhanced performance and reduced operational costs for commercial and industrial applications.
