CubeSat solar panels on satsearch

Unlike larger satellites where the surface area available on the external structures is much greater, CubeSats and nanosatellites have far less volume that can be given to solar panels.

A 1U CubeSat for example will have an area of just 10 cm x 10 cm on each face in order to accommodate a solar panel.

In addition, solar panels can also not be mounted on surfaces that need to accommodate other components, such as planar antennas, optical sensors, camera lenses, and access ports.

In spite of these limitations there are several different solar panels available on the market that work with the severe physical restrictions imposed by the CubeSat (and smaller) form factor.


Key performance criteria for selecting the right solar panel

Aside from the size of the panels themselves, there are several important criteria to consider when choosing the right solution for your CubeSat solar panel:

  • Generation of energy in accordance with the orbit functioning requirements of the satellite
  • Compliance with the voltage and current levels acceptance by the power conditioning and distribution system within the satellite
  • Compliance to launch vehicles and the loads specified by launch providers
  • Compatibility with the temperature range that the satellite can face during launch and in orbit
  • Compatibility with all the materials used within the satellite and the nature of their behavior due to thermal expansion and contraction during launch and orbit
  • Reliable actuation for deployment of the panels (there are multiple options available such as flexible joints, shape memory alloys, torsion spring in hinge, coil springs, motors, etc.)
  • Ability to withstand physical launch stresses

Integration of solar panels with other sub-systems

For a CubeSat solar panel to work effectively it needs to be successfully integrated into the satellite alongside the other equipment in use.

Here are a few tips and tricks on how to incorporate a panel with other sub-systems in order to gain more value than simply generating power in a CubeSat:

  • To allow easier integration and flexibility while assembling a CubeSat, solar panels can be efficiently packaged along with other sub-systems, such as structures. A mechanical back plate design, based on aluminium machined alloy, may be used with standard solar panel mounting holes to perform such an integration.
  • Sensor packages including an accelerometer, gyroscope, magnetometer, coarse sun sensor and temperature sensor (external and internal) can be integrated into such a design in order to accommodate elements of the attitude control and electrical power system.
  • Multiple independent Remove Before Flight (RBF) circuits can be added in different locations (X,Y or Z solar panels) in order to comply with different deployers’ and launch service providers’ requirements.
  • It is possible to embed magnetorquers that can be configured to provide different levels of torque and power consumption in order to comply with different mission profiles.


Deployable Solar Panels

Traditionally CubeSats did not have deployable arrays to generate more power for advanced missions or more power-hungry payloads.

Today, due to advances in new technology and electronic minitiarisation, it is possible for CubeSats to use various deployable solar array solutions.

Such technology typically utilises a ‘hold down and release mechanism’ using a spring-loaded slider that ensures safe and effective hold down functionality for the deployable panels.

The slider is locked by a locking arm system that can be released with a dedicated pin-pusher for deployment.
