Abstract: In order to improve the gain of a photovoltaic solar energy system, the system comprises: a plurality of bifacial photovoltaic solar cells, defining together a direct absorption surface as well as an indirect absorption surface, both surfaces being opposite and intended to absorb a solar radiation energy; a support chassis for supporting the cells, the chassis comprising a support structure on which the cells are attached. The chassis further includes a suspension for suspending the support structure, the suspension comprising a top end connected to a first end of the support structure, and the suspension defines a reflective surface configured to reflect light towards the indirect absorption surface defined by the cells.
