125 tons of carbon-dioxide emissions per year. It is equipped with 74 of Soitec’s high-efficiency CPV trackers, each using 168 Concentrix CPV modules, along with two central inverters of 500 kW each to ensure reliable power distribution to the grid.
and committed to developing this market in Italy.”
Fully owned and operated by Soitec, the new solar plant will supply electricity to Enel, Italy’s largest power company. Local Italian construction companies provided engineering, procurement and construction (EPC) services for the solar power plant while efficient central-inverter technology was provided by Schneider Electric.
Emcore unveils commercial rooftop CPV system
The system incorporates the firm’s III-V compound semiconductor multijunction solar technology
Concentrix tracking system
Concentrix technology uses optimised III-V-based triple-junction solar cells (GaInP/GaInAs/Ge) in which three different types of solar cells are stacked on top of one another. Each cell type is designed to convert a certain range of the solar spectrum: short wave radiation, medium wave radiation and infrared.
Operating at higher efficiency than conventional solar PV panels in converting sunlight into electricity, Soitec’s systems maximise energy production throughout the day by incorporating multjunction solar cells and dual-axis tracking systems that maintain an optimal angle to the sun. CPV is the most attractive solar technology in high solar resource regions around the globe.
“Completing this solar power plant marks a major milestone for Soitec in Italy while also demonstrating all of CPV’s advantages in this part of the world,” says Gaetan Borgers, executive vice president of Soitec’ Solar Energy division.
“This project has allowed us to show that CPV’s leading efficiency and ability to provide a steady, long-term energy supply without consuming excessive amounts of land and water make it exactly the right technology for Italy. We are uniquely positioned with a cost-effective power generation technology at high levels of efficiency
Emcore Soliant 1000
The Emcore Soliant 1000 is designed to generate solar power for commercial buildings with high energy demands. The system offers one of the highest energy production densities of any available solar system, making it a very cost-effective solar solution for commercial rooftops in regions with high Direct Normal Irradiance.
Emcore’s Soliant 1000 generates more than 500 watts peak per panel (18 watts peak per square foot), requiring approximately 28% less rooftop area

Emcore Corporation has announced that the Emcore Soliant 1000 Commercial Rooftop Concentrator Photovoltaic (CPV) System is now available for pre-production orders.
The Soliant 1000 is powered by Emcore’s III-V multijunction solar cell technology.
