Lightweight Solar for High-Altitude Balloons

Challenge

High-altitude balloons and airships require reliable power for:

• GPS and telemetry systems.

• Instrumentation payloads.

• Radio communications.

• Environmental sensing equipment.

The platform demanded:

• Minimal mass contribution.

• Mechanical integrity at altitude.

• Stable voltage and current output.

• Reliable performance in extreme environmental conditions.

Approach

Custom lightweight solar modules and attachment methods were engineered to meet strict mass and integration constraints.

Applications required:

• Lightweight substrate and encapsulation materials.

• Secure attachment compatible with balloon envelope structures.

• Optimized voltage and current alignment with payload electronics.

• Low-loss wiring harness for distributed power collection.

Design emphasis focused on minimizing mass while maintaining structural and electrical integrity.

Solution

Integrated lightweight solar assemblies deliver defined power output to high-altitude payload systems without exceeding mass constraints.

The system supports sustained electronics operation in extreme altitude environments.
