High Altitude Balloon

Loon Project solar powered inflatable balloon


High-altitude balloons and airships rely on an increasing amount of electronics to perform critical functions in a highly challenging environment. GPS, instrumentation, radio equipment, and other electronics systems require a robust solar power system. Customers need a power source that is lightweight and reliable.



PowerFilm's product development team has worked with several organizations that require solar power for high-altitude balloons. We have responded by designing custom, extremely lightweight panels and attachment methods to meet their specific needs. These applications call for some of our lightest weight substrates and encapsulation materials. Beyond the basic panel voltage and current capability, a key design feature for this application is a wiring harness that collects the power and gets it to the appropriate location with minimal loss.



We designed lightweight and reliable solar power solutions for high-altitude balloons delivering the energy they need in a demanding environment.
