The solar compact station should be designed and assembled in a maximum of two containers and have a lifetime of at least 20 years. The containerized solar compact station should be designed with an internal auxiliary system for each compartment to ensure nominal output power up to at least 50° C ambient temperature.

The solar station container should be insulated with fireproof material to maintain waterproofness over time and efficient thermal insulation.
