Located in Guangming New District of Shenzhen City, the project covers a land area of over 50,000m² and is equipped with thin film photovoltaic solar cells module production line that has the annual output of 50MW. It is planned that the production line will be put into full-scale commercial production in the first season of 2010. The main equipment building adopts all-steel structure frame system and full-bolt connection. The project’s features and difficulty points of construction: Japanese standard nodes are adopted as box column nodes and this is the first time of such application in China, so it’s very difficult for processing; this project adopts bolts for connection wholly, resulting in higher processing and installation accuracy.
