SHANGHAI, Apr 11(SMM) - The domestic output of polysilicon stood at 54,500 mt in March, up 7.9% on the month and 51.2% on the year, according to SMM estimate. The MoM increase was contributed by two factors, including the number of production days in March increaseing by three days compared to February and the rising in Sichuan's new production capacity. The output in April will dip slightly due to the small-scale maintenance at two silicon plants in Sichuan and Xinjiang. The rising production capacity among Asia Silicon, Xinte Energy and South Glass totalled 60,000 mt with the release of new capacity slower than expected. The domestic output of polysilicon is expected to be 56,000 mt in April, up slightly from March.
