Brazil’s government to review project for Brazilian-Paraguayan vertically integrated PV production


Brazil’s Minister of Energy and Mines, Fernando Coelho Filho, will meet on January 16 with the representatives of a consortium that is planning to build what would be Brazil’s and Latin America’s first vertically integrated PV module factory.

According to a press release from the project’s developers, Brazilian-Paraguayan power company, ITAIPU and the industry association of the Brazilian state of Paraná FIEP, the feasibility study for the factory – which would have an annual production capacity of 1.7 GW and would produce around 6,800,000 solar modules with an output of 250 W per year – was conducted by Germany’s research institutes, Fraunhofer IPA, Fraunhofer ISE, ZSW and independent consulting firm, Viridis-iq in 2015.

The project, named Green Silicon, is also being planned with the support of German industry association, Solar Cluster Baden-Württemberg, based in Stuttgart, since 2013. Manufacturing activities would cover the entire value chain, from silicon production to solar module manufacturing, and would be built partly next to a hydroelectric power plant that boasts the world’s highest annual energy production, the Itaipú Dam, which is located in Paraná close to the border with Paraguay and partly in Paraguay itself.

“During the full phase of operation of the Green Silicon project,” said Itaipú in the press release, “the expectation is to create 4,310 direct jobs, generating income in the amount of €54.8 million and value added of €113.4 million per year. The governments of Brazil and Paraguay can still benefit from tax revenues.”

In the first phase of the project, Itaipú and FIEP will set up ingot and wafer production at an unnamed location in Paraguay. The polysilicon for the factory, the two entities said, will be imported from undisclosed international manufacturers.

The second part of the project envisages the setting up of the cell and module production in Brazil, and eventually in Paraguay.

As for the feasibility study, each of the three Germany research institutes in Baden-Württemberg has brought its respective skill-set to the project: ZSW has investigated the potential of the Brazilian and global markets and how the development of a local PV infrastructure would affect employment and value creation in the region; Fraunhofer ISE was responsible for silicon PV, the solar cell manufacturing process and advanced training; and Fraunhofer IPA, a research institute for production engineering and automation, has analyzed the supply chain infrastructure, economic feasibility and environmental sustainability of the proposed project.
