Enel North America, through its affiliate 3Sun USA LLC, is building an industrial-scale production facility in the U.S. for the manufacturing of photovoltaic modules.
The proposed facility is expected to have a minimum production capacity of 3 GW, with the possibility to scale production to 6 GW annually.
“Recent policy tailwinds from the Inflation Reduction Act have served as a catalyst for our solar manufacturing ambitions in the U.S., ushering in a new era of made-in-America energy,” says Enrico Viale, head of Enel North America. “With this announcement, it is our intention to bolster a robust domestic solar supply chain that accelerates and strengthens the U.S.’ transition to clean energy. In doing so, we are creating thousands of new jobs, supporting local economies and providing stability to the solar industry.”
Currently, Enel is evaluating possible sites for the new factory and expects to begin construction in mid-2023. It’s anticipated that the first panels will be available to the market by the end of 2024. Fewer than five large-scale solar module manufacturing facilities (over 1 GW) are currently operating in the U.S., while annual U.S. solar PV installations are projected to grow from 16 GW in 2022 to 41 GW by the end of 2025, according to Wood Mackenzie.
Enel will leverage its expertise and experience from its 3Sun Gigafactory in Catania, Italy, which is set to become Europe’s largest factory producing high-performance bifacial photovoltaic modules. Enel intends to replicate the Gigafactory factory in the U.S. to produce bifacial heterojunction (B-HJT) PV cells that capture more sunlight as the cells can respond to light on both front and rear surfaces.
3Sun is already producing high-efficiency cells, breaking a record in 2020 by achieving 24.63% efficiency. Through a R&D program, the PV panels will be further developed to also incorporate a tandem structure, which utilizes two stacked cells that allows for more light to be captured compared to single-cell structures, yielding higher overall cell efficiency. The combination of bifacial PV panels and tandem cell structure offers significant efficiency improvements, which will enable PV modules to exceed 30% efficiency, securing higher average energy production. The technology’s lower degradation ensures a longer useful life for modules, and the cells’ high density is conducive to a variety of applications, including land-constrained utility-scale installations or rooftops.
