ISISPACE provides customized small satellite/CubeSat solar panels and arrays for standardized prices. As most satellite missions are special, ISISPACE offers a solar panel solution that takes into account accommodations for sensors, apertures, etc. Our innovative design with an aluminium substrate with a flex-PCB overlay for the cells allows for most mission-specific customization without additional non-recurring engineering charges. Body mounted panels and deployable arrays are supported for 1U to 12U CubeSat sizes. Our space-qualified cells are provided with extensive characterization and test reports. Our expertise allows us to carry out custom work from concept design to production to meet your needs and requirements.
