SunPower Corporation announced the sale of more than 70 megawatts (MW) of cell packages to the Huaxia Concentrated Photovoltaic Power Co., Ltd., joint venture (JV) in Inner Mongolia, China. These packages will be used for the first phase of two SunPower™ C7 Tracker (C7) projects, which includes a 20-MW project in Saihan and a 100-MW project in Wuchuan. Both are located in Hohhot, Inner Mongolia and completion is expected in 2015.
The agreement for the Huaxia Concentrated Photovoltaic Power JV was initially signed in December of 2012, and officially approved and registered in November of 2013. The JV includes SunPower, Tianjin Zhonghuan Semiconductor Co., Ltd., Inner Mongolia Power (Group) Co., Ltd. and Hohhot Jinqiao City Development Company, Ltd. Its focus is to manufacture and deploy SunPower's proprietary C7 concentrator technology in the Chinese market. To date, a 300-MW C7 receiver manufacturing facility has been set up in Jinqiao Development Zone, Hohhot, Inner Mongolia, and a 50-MW production line is now in operation.
The C7 combines single-axis tracking technology with rows of parabolic mirrors that reflect light onto SunPower's high efficiency, third-generation Maxeon solar cells with efficiencies of up to 24.5 percent. These mirrors will reduce the number of cells required to generate electricity, lowering the levelized cost of energy when compared to competing technologies. For example, a 400-MW C7 power plant requires less than 70 MW of SunPower cells. Through significant localization of C7 manufacturing and supply chain, and deployment of the C7 for large-scale power plant projects, it is expected that this venture will facilitate the development of a low cost, high volume supply chain and accelerate the cost reduction roadmap of this product.
