Arinna builds ultrathin solar panels specifically for spacecraft. Its technology is based on a new material - transition metal dichalcogenides that are atomically thin semiconductors. This technology allows for extremely flexible cells that the company claims are cheaper, more durable than legacy space solar panels and 32% more efficient. Arinna’s technology also won’t require protective coverings, will last 15 years on orbit, and can be delivered within weeks. The company expects to have its first products being tested on orbit before the end of 2026. After qualifying their photovoltaics in space, the company hopes to build a facility that can mass produce the stuff at megawatt scale in 2028.
