Shandong Dragon photovoltaic energy co., Ltd. was founded in 1997, formerly known as Wu Cheng Teng long air conditioning group, officially changed its name to Shandong Dragon PV in 2008 new energy co., Ltd.. now set Wu Cheng Dragon products company, constant-source geothermal heat pump co., Ltd., Texas yida ceramic Crucible co., Ltd., Shandong Crystal Wei electronics technology co., Ltd. four branches. right of Wucheng County, is located in Shandong province, Shandong town development zone, West of Beijing-Kowloon Railway, North of Beijing-Hangzhou Grand Canal, East of Beijing-Shanghai Expressway and Jingfu, South of Jinan, the capital, the transportation is convenient, and superior location.

company was originally engaged in the central air conditioning, glass fiber production and sales of ventilation products, has become a leader in the industry at that time. after years of development, group leader of courage and innovation, grasp the business opportunities. did not abandon traditional industry on the basis of, the company gradually on the increase of quartz crucible production, silicon and sliced items. is mainly engaged in the semiconductor material, cutting of single crystal silicon, polycrystalline silicon, monocrystalline silicon, solar photovoltaic cells, modules, solar panels, solar lighting systems, photovoltaic systems, quartz crystal, quartz crucible, graphite, quartz device products. the company covers an area of 320 acres, an area of 56,000 square meters, the staff more than 680 people, experts, 6 of them were engineers and 29 people, 40 engineers, technicians and 52, accounting 9 people, Economist at 8, registered capital of 130 million Yuan, its scale numbered in the private enterprise in Wu Cheng.

companies with large modern super high steel structure workshop, 14, have high level of cleaning air conditioner two sets, made from pure water equipment, cut off the oven, manual dry sandblasting machine pump modern equipment, quartz crucible, monocrystalline silicon products.

2005 Dragon Witt Group invested 50 million dollars to set up the Shandong ceramic electronic technology co., Ltd., mainly the production of Silicon of high-tech products. is a complete lattice has the basic structure of single crystal silicon crystals, different directions of nature is a good semiconductor materials, purity requirements of 99.9999999% or more. mainly used in the manufacture of semiconductor devices, solar cells, used in the manufacture of high power rectifier, transistor, diode, switching devices, and so on, this product filled the blank inside the province, products in short supply.

2007, Dragon Group invested 18 million dollars, set up Texas yida ceramic Crucible co., Ltd., production of containers for Silicon. quartz crucibles in stand in the production process of 1420 ° c above, after 20-50 hours of tests. national technology for quartz crucibles have been included in the "torch plan", with emphasis on support. the national production of quartz crucible is only about ten, limited number of products, production capacity is far from satisfying the market needs, the market potential is huge.

Shandong free Dragon PV new energy limited. adhere to to technology for pilot, to quality seeking survival, face market fierce had race, constantly increased technical input, company for Shandong province heavy contract and trustworthy with enterprise, and in dezhou city hundred city letter enterprise, and City County technical input advanced units, products demand, 2007 sales up 230 million, profits up 6.42 million Yuan.
