This paper presents the development of solar arrays for Argentine satellite missions performed within the frame of cooperation agreements between the Argentine National Atomic Energy Commission (CNEA) and the Argentine National Commission for Space Activities (CONAE). Relevant issues such as simulation and design, solar cells characterisation, set up of soldering and bonding processes, radiation damage and development of testing techniques, are reviewed. A chamber for testing solar cells and other devices in a simulated space environment, and the integration and tests of two engineering models for qualification of space technology processes are described. The requirements and solar array design for 3 missions, Aquarius/SAC-D and SAOCOM 1A and 1B, are presented. Finally, the flight model for the SAC-D mission, which was launched on 10 June 2011, is outlined, and telemetry data analysis from the first stages of the mission is presented.
