In order to fully develop and utilize of the abundant solar energy resources of our country and better satisfy the increasing demand for energy from economic and social development. Shandong Dahai Group CO., Ltd and Shanghai Wealth New Energy Investment CO., Ltd make cooperation and found Shandong Dahai New energy Development CO., Ltd. It is dedicated to develop¼Œmanufacture and sale of solar mono-silicon poly-silicon wafer and solar cell.With total investment of RMB 8.2 billion yuan, the construction includes four phases. With investment of 1.88 billion yuan, annual capacity of the first phase is 450MW. Up to postpartum of the first phase project, the annual capacity of mono-silicon will reach 150MW, poly-silicon 300MW. To further deepen industry chain. In 2011 we invest 2 billion yuan to complete the second phase construction of 500MW solar wafer production project. After the completion of the two projects, the annual capacity of solar wafer will reach 1000MW, annually digesting raw material of mono-silicon and poly-silicon 10, 000 tons. As plan, the subsequent projects are in succession in 2012. Until 2013, the whole project will be completed and put into production. At that time, the annual capacity of solar wafer will reach 2000MW, solar cell 1000MWThe project adopts the most advanced production technology in the world and the main crafts adopt the most advanced, stable, low energy equipments in domestic, which are the first-class in the same industry. The single crystal growth furnace in the workshop adopts Japanese technology. The poly-crystal ingot furnace, DSS450 is from American GT, it has the most feed charge and is the most mature machine in machines of domestic. In conclusion, with the advanced equipment and guaranteeing of product quality controlling, our product quality can provide the most persuasive guarantee for the need of downstream solar cell factories, also the product can adapt to demand change of downstream market.
