The SL1500/82 turbines will be installed in a 34.5MW wind farm in Sergipe, Brazil that is being developing by Desenvix, a subsidiary of the Engevix engineering group.
Commissioning of the Barra dos Coqueiros wind farm is expected to be carried out by July 2012. To meet the schedule, Sinovel will deliver the turbines by December 2011.
Sinovel senior vice-president Lecheng Li said: "This deal is a good beginning for both Sinovel and Desenvix. It strengthens the green-energy presence of Desenvix and opens the door for Sinovel to the Latin American market.
"With the successful model of the Barra dos Coqueiros wind farm, the whole market is now aware that the wind farm solution from China is not only attractive but feasible."
Sinovel has also decided to build a manufacturing facility in Brazil to show its strong commitment to this market, the location of which is under investigation, said Li.
Sinovel has been the largest Chinese wind-turbine supplier since 2008. The company almost doubled its global market share in 2009, making a major leap forward from 5.0% to 9.2%.
Desenvix Energias Renovaveis S.A., launching in May 1995. It has developed or contributed to the implantation of more than 5,000MW of electricity generation in Brazil.
