Solestial, Inc., a US-based solar energy company for space, recently announced signing a Space Act Agreement with NASA’s Glenn Research Center. The collaboration will advance the performance and resilience of ultrathin silicon solar arrays in specific space environments. Solestial will provide solar power modules for testing within NASA’s Glenn Research Center Plasma Interaction Facility. NASA will then characterize changes in electrical performance and share resulting data to guide necessary design improvements. The primary focus of the collaborative iteration cycle is refining the solar array architecture for enhanced durability and performance in lunar and orbital environments. This agreement will also support NASA in its broader campaign to develop active electrostatic discharge mitigation strategies for photovoltaic systems. Solestial has previously focused on developing self-curing radiation-damage silicon technology.
