Flexible Solar Power Modules
Our flexible, low mass, and radiation-hardened solar cell allows us to reimagine packaging. We replace cover glass and composite substrate with polymer layers, resulting in a thin solar power module that can withstand up to 10 years in a variety of destinations in space.
-
Integrated Solar Power Modules
Our flexible solar power modules can be paired with rigid or flexible substrates. Solestial offers module-to-substrate integrations to deliver integrated solar power modules that are ready to install on your spacecraft.
-
Solar Array
We are partnering with a variety of firms to offer complete solar array capabilities. Our flexible solar power modules can be integrated with a wide range of solar array deployment systems.
