A diamond solar plant has been unveiled by national electricity supplier ENEL on Via Antonio Gramsci in Rome's Valle Giuila area.

The "Diamante" photovoltaic power plant converts solar energy into clean electricity, and even works at night when there is no light.

The technology behind the project is based on a highly-efficient system that provides energy storage through lithium iron batteries.

It has an 8-m diameter, is built with 38 photovoltaic panels made of monocrystalline silicon, and its surface is covered by glass panels that protect the structure from the wind.

The solar sphere was constructed opposite La Sapienza’s architecture faculty, on a site provided by the university, and is located beside the Japanese Cultural Academy.
