Solar drones are unmanned aerial vehicles (UAVs) powered by solar energy, using photovoltaic (PV) panels to recharge batteries mid-flight. They combine long-endurance flight with zero-emission operation, enabling missions that traditional fuel-powered drones cannot achieve.
Solar Panels
Integrated into wings/fuselage to capture sunlight.
Use high-efficiency cells (monocrystalline or thin-film).
Energy Storage
Lithium-ion/LiFePO4 batteries store energy for night/low-light flight.
Electric Propulsion
Brushless motors powered by solar + battery hybrid systems.
Autonomous Operation
GPS-guided with AI for navigation, data collection, and obstacle avoidance.
| Type | Purpose | Example Models |
|---|---|---|
| Fixed-Wing | Long-endurance surveillance, mapping | Zephyr (Airbus), PHASA-35 |
| Multirotor | Short-range inspections, agriculture | Sunbirds (China) |
| Hybrid VTOL | Vertical takeoff + long flight | AtlantikSolar (Switzerland) |
| Stratospheric | High-altitude pseudo-satellites (HAPS) | BAE Systems’ PHASA-35 |
Border patrol: Months-long monitoring (e.g., Airbus Zephyr for military ops).
Disaster response: Assess hurricane/earthquake damage without refueling.
Wildlife tracking: Monitor poaching in protected areas.
Climate research: Atmospheric data collection at high altitudes.
Internet/5G coverage: Facebook’s Aquila (defunct) and HAPS projects.
Crop scouting: Multispectral imaging for precision farming.
Stratospheric studies: Replace weather balloons with solar drones.
✅ Unlimited Flight Time: Fly for weeks/months (e.g., Zephyr holds the record at 64 days).
✅ Zero Fuel Costs: Solar energy is free after initial investment.
✅ Eco-Friendly: No CO₂ emissions or noise pollution.
✅ High Altitude: Operate above weather (20–70 km altitude for HAPS).
⚠ Weather Dependency: Cloudy days reduce efficiency.
⚠ High Initial Cost: Advanced materials and tech increase prices.
⚠ Payload Limits: Solar panels reduce space for sensors/cargo.
