“This partnership with Calisolar is an excellent opportunity for Suntech to accelerate the development of the solar industry in Ontario and meet the growing solar demand across Canada,” said Steven Chan, president of Suntech's North American operations. “We have looked at the various alternatives for investment in Ontario and have determined that our continued commitment to the silicon refining industry provides the best opportunity to create long-term sustainable jobs given the product's export viability.”

“This agreement with Suntech, a recognized global leader in solar products, marks a significant milestone in Calisolar's expansion,” said Calisolar CEO Sandra Beach Lin. “Calisolar's unique silicon refining technology was developed in Ontario and provides significant cost and environmental advantages compared to traditional processes. Together with Suntech we will be able to expand our operations in Ontario and bring long-term, sustainable jobs to continue to serve this exciting, emerging market for solar energy.”

“We are very excited about this initiative and have been working with the Province of Ontario to seek clarification regarding the local content regulations so that we can move forward in the most efficient manner possible. This is a unique opportunity to leverage the economic advantages of technologies and expertise found only in Ontario for use in cost effective, large scale, renewable energy,” concluded Chan.
