The company is mainly engaged in the research, development, production and sales of high-performance solar cells, battery modules and LED lamps, as well as the design, sales and installation of grid-connected and off-grid photovoltaic application systems. Casting and forging production equipment advanced, complete industrial chain, is a high-tech photovoltaic enterprises with independent intellectual property rights. The company has passed the quality management system certification, and the solar modules have passed three international certifications :CE, FCC and RoHS. At present, the company has the production capacity of 50MW solar cells and 50MW solar modules. By the end of 2012, battery and module production capacity will be expanded to 100 to 150 megawatts, respectively. Annual output value of seventy - seven million, profit and tax twenty million. Selective emitter forging and casting solar cells are improved versions of existing silicon solar cells. Its conversion efficiency is higher (average 17.5%), its performance is more stable, and it is less affected by the change of the main raw material silicon wafer material. If the commercial mass production of SE high-efficiency solar cells is realized, it will be a milestone in the development strategy of solar cell "science and technology leadership" enterprises, enabling Chinese photovoltaic enterprises to reach the level of conversion efficiency in commercial production. In order to ensure the product quality and the stability of the production process, it is urgent to need the help and guidance of experts.
