Description
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.

FAQ
Can you provide custom size solar panels?
Yes, we can provide custom-sized solar arrays, accommodate cut-outs, embed antennas, and implement custom deployment angles. please reach us out with your requirements for such panels.
Can you accommodate cut-out, notches or specific mounting holes on your panels?
Yes, the mechanical layout of our panels is fully customizable.
Is the surface area of your solar cells different from other vendors?
Our default solar cell size 30.18cm² per cell (Azurspace triple-junction cells). However, we can implement other sized cells upon requests.
Can you accommodate specific solar string configuration (amount and voltage)?
Yes, the electrical layout is fully customizable to match your power system requirements.
Do you have a magnetic loop mitigation strategy on your panels?
Yes, our solar panels are designed in such a way that the magnetic moment generated by currents flowing through the panels is minimized in order not to impact your satellite’s attitude control system sensors and actuators.
