The vigorous development of the global photovoltaic market depends on the reduction of the cost of electricity, and the photovoltaic conversion efficiency is the core factor for the reduction of electricity costs. GCL Group, the world's largest manufacturer of solar polysilicon wafers, recently announced that it will invest 10GW of single crystal projects in Zhongwei City. The mainstream solar cell manufacturers SolarWorld, Panasonic and Jingao have laid out the single crystal market. According to reports, SolarWorld plans to deploy a total of 500MW of monocrystalline silicon rods in the former Bosch solar production facility in Arnstadt, Germany, and announced that it will deploy five-grid battery modules for production at its manufacturing base in Oregon. In progress, the company said that this application can achieve a conversion efficiency of 21.51% for N-type single crystal PERC cells. The company plans to produce 300W single crystal modules (60-156*156) in Europe and the United States this year.
JA Solar, the world's largest solar cell manufacturer, recently said that it has increased its P-type monocrystalline silicon solar cell (PERCIUM) from 80MW in 2014 to 400MW in 2015.
Matsushita, the largest solar cell manufacturer in Japan, announced that it will invest 9.5 billion yen in the Shimane plant (Shimane Sanyo Electric Co., Ltd.) and the Shiga plant to produce solar cells. The expansion will increase the company's annual production capacity by 150 MW. By March 2016, the total capacity of Panasonic HIT monocrystalline solar cells will increase to more than 1 GW, in addition to the two domestic plants, including Kedah in Malaysia. And manufacturing facilities in Osaka Sesame County.
Since 2014, mainstream battery manufacturers such as Taiwan and South Korea have expanded their production by almost 100%. In contrast, in the polycrystalline market, due to bottlenecks in battery conversion efficiency, the cost of polysilicon wafers is limited, and the overall share of the polycrystalline market is declining. With the development of single crystal growth, the popularity of diamond wire flaking and the continuous improvement of the efficiency of single crystal cells, the advantages of single crystal competitiveness are becoming clearer, and more and more photovoltaic manufacturing enterprises will increase the share of single crystal and lay out the single crystal market.
