During the prefabrication phase, the concrete units that make up the collector’s load bearing structure are made. These are made using semi-automatic machines capable of moulding units or beams in various shapes. The units, once assembled, make up the frame (or load-bearing structure of the solar collector).

The formworks were developed, assembled and tested in Biasca in 2012 and are currently installed and operational at the Ait-Baha site.
