Solar Arrays

With several systems delivered and in orbit SpaceTech has developed into a provider of solar arrays systems ranging from deployment mechanisms for pre-defined deployable solar array structures to complete systems including photovoltaic assemblies, deployment mechanism and electronics ready for the integration onto the customer's spacecraft. In order to ensure compliance with the customer's mission needs, the design of the solar panels includes structural/thermal design and analysis activities for the substrates as well as electrical design and analyses work for the photovoltaic portions. For the power performance analysis, in-house power simulation tools come into application.
