This refined silicon block is an intermediate step in the manufacturing of cells for photovoltaic panels.

Rejected from a factory due to a manufacturing defect, and laser-engraved for the exhibition, its cutting into cells, once assembled into modules, could have produced 60,000 kWh of renewable electricity over its lifespan (30 years).

The Soft Power engraving contrasts with the sharp angles and mass (an energy symbol) of the artwork.
