To provide the required 5W of electrical power, the PicSat satellite encompass 2 deployable solar panels of 2U length each. It gives a total of 50cmx10cm of surface exposed to the Sun.

Because the solar panels deploy on two opposite sides (for redundancy), the VHF/UHF antennas deploy on the other two faces. They are on opposite edges to maximise transmission, and decrease the risk of interference.
