The 160 million yuan ($22.8 million) deal, financed by ICBC Brazil, will involve shipments of photovoltaic modules and inverters produced by Longi Green Energy , the world's top solar manufacturer, according to state-run Xinhua news agency.
CGN started construction on the project, a 165MW solar power plant in northeastern Brazil's Ceará, early this year, the Xinhua report said.
CGN Chairman Yao Zhigang was quoted as saying that the financing "offers yet another successful example of RMB internationalisation, and at the same time effectively controls project construction costs".
China's central bank authorised ICBC Brazil to become a renminbi clearing bank in February 2023, saying it would promote bilateral trade and investment.
Longi did not immediately respond to a request for comment on Friday evening.
