Description

ISIS provides a range of high performance CubeSat compatible solar panels. The panels come in 1-6U size with sun and temperature sensors and other custom options available on request. Its space qualified cells are provided with extensive characterization and test reports. Thanks to its very thin and customisable design, it fits on all CubeSat structures and subsystems such as ISIS antenna system.
