Solestial Products

  1. Solar Cell

    Our ultrathin, flexible, silicon heterojunction solar cells offer 20%* efficiency and are the only silicon solar cells on the market capable of low-temperature annealing of radiation damage.

    We engineer our solar cells in-house for optimal performance in space, leveraging commercially available silicon wafers.

    * Solar cell statistics reflect Generation 2 product available in late 2024.
  2. 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.
