As global adoption of solar energy continues to accelerate, researchers and engineers face a fundamental spatial challenge: how do you generate more electricity without consuming more land?

Cosimo Borrello and Ferdinando Gioia – co-founders of the Italian photovoltaic technology startup A.M.P.S. – together with a team of researchers from the “Mediterranea” University of Reggio Calabria developed and field-tested a dynamic double-layer photovoltaic prototype designed to maximize solar power output per square meter of ground area.

The challenge: overcoming land constraints

Conventional single-layer solar farms require significant spacing between rows to avoid mutual shading during solar tracking. While tracking raises energy yields per module, the extra space reduces overall energy production per unit of land.

To solve this, the innovators at A.M.P.S. and the university stacked two vertically aligned layers of bifacial solar mini-modules within the exact same ground footprint as a single-layer setup.…
