3SUN 2.0: Production Launch for Cutting Edge Bifacial Photovoltaic Panels

Enel Green Power’s factory in Catania launches a new assembly line for the production of bifacial crystalline silicon panels, which will be followed by the installation of a production line of bifacial HJT panels, the first example of this high-performance technology in the world. A total investment of 100 million euro, including 20 million for the Enel Innovation Lab in Catania.

The conversion project of Enel Green Power's 3SUN factory kicks off, a project which will make the Catania industrial facility the first worldwide and exclusive manufacturer of HJT bifacial photovoltaic panels, which are based on heterojunction technology. This technology features the junction of two different kinds of silicon, amorphous and crystalline, allowing for particularly high yields.

Antonio Cammisecra, Head of Enel Green Power, presented today the factory’s development plan, called 3SUN 2.0, in the presence of the Enel’s Chairman Patrizia Grieco, and the 3SUN’s CEO Antonello Irace.

 

“We are especially proud of this project, which is based on technological research and innovation, two essential drivers for a company like Enel.”
– Patrizia Grieco, Enel’s Chairman

 

An Investment in Innovation

The technological conversion programme for the 3SUN factory, Europe's largest photovoltaic panel manufacturing facility, entails an investment of over 80 million euros, partially financed by the European research and innovation programme Horizon 2020 European Call LCE-09-2016-2017, through the Ampere project, by the Ministry of Economic Development and by the Region of Sicily.

The investment for the factory is complement by the 20 million euro investment for the Enel Innovation Lab in Catania, where the company has specialised laboratories that are experimenting innovative renewable energy technologies.

 

“In an increasingly competitive and fast-paced global market, we count on an open-management model that is continually being enriched with new incentives and skills, thanks also to the positive interaction with the external business environment. Right here in Catania we can proudly point to the beneficial effects of following this philosophy, as shown by the excellence of the 3SUN factory and its interaction with our Innovation Lab.”
– Patrizia Grieco, Enel’s Chairman
 

The contribution of the Catania facility is providing Enel Green Power with a decisive competitive advantage, as it is the only integrated renewable player that can rely on an internal factory for the manufacturing of solar panels to satisfy part of its needs in projects all over the world.

 

“This new production line will let us strengthen our worldwide leadership in the renewables sector, while at the same time boosting the expansion of our technological hub in Catania, proudly established in Italy. We expect that this project will stimulate the entire industrial sector in Italy, and photovoltaics in general.”
– Antonio Cammisecra, Head of Enel Green Power

 

More Efficient and Competitive Technology

The technological leap entailed by the new photovoltaic panel is significant, with efficiency rising from the 10% yield of the previous model to around 18% for the 2018-model bifacial panel, and about 20% for bifacial HJT panels from 2019 onwards. In 2018 maximum power will reach 360W per panel and from 2019 onwards 395W per panel, compared to the previous 140W.

The use of bifacial panels allows for solar radiation to be captured even by the panel’s rear surface, increasing energy output by approximately 10-15%. As a result, it is possible to install fewer panels, thus reducing the required footprint.

Moreover, whereas prior panels could only guarantee a 25-year lifespan, the new ones are so robust that they will last more than 30 years, ensuring high performance even in extreme weather conditions.

 

“The launch of this new photovoltaic technology is not only a milestone for Italian technology but is also the premise for relaunching the 3SUN factory and putting the skills of its workers to good use.”
– Antonio Cammisecra, Head of Enel Green Power
 

 

3SUN 2.0: Three Steps Toward the Future

The 3SUN 2.0 project comprises three stages: the first, starting in the second quarter of 2018, involves the installation of a new assembly line of crystalline cells to be used to manufacture bifacial panels. The assembly line will have a maximum production capacity of 80 MW per year.

The second stage involves installing a new production line for HJT cells, which will be operational starting from the first quarter of 2019, and with a maximum production capacity of 110 MW per year.

Finally, the third stage will double the HJT production capacity reaching 200 MW per year in the third quarter of 2019 and may eventually reach 250 MW per year upon future optimisations.

The factory will operate in a continuous cycle, 24 hours a day and 365 days a year. When the technological conversion is complete, the factory’s output will reach around 1,400 panels a day, for an annual total of about 500,000 panels.

 

A Meeting Place for the Best

Thanks to the new investment, the Innovation Lab, which together with the 3SUN factory makes up Enel's Sicilian technological hub, will become a campus devoted to innovation and an accelerator for young entrepreneurs aimed at encouraging research in the energy sector.

The Innovation Lab will host local and national start-ups, national and international research laboratories, it will be linked to the world of innovation even through Enel's innovation hubs, thus becoming a crossroads of excellence in the field of innovative technologies.
