National PV Standardization Annual Meeting is held frequently

The three-day National Solar Photovoltaic Energy System Standardization Technical Committee 2011 Annual Meeting ended in Changzhou on the 16th. At the meeting, more than 120 experts and leaders from all over the country had a heated discussion on how to further adopt the scientific standard system to regulate the healthy development of the photovoltaic market. This year's annual meeting further standardized the standard system of the photovoltaic industry, filled the blank of some domestic PV product technical standards, and defined the direction for the further development of photovoltaic standard work and the right to fight for international standards. The participating experts agreed that the government and relevant authorities should continue to accelerate the establishment and improvement of the photovoltaic system standards system to guide the healthy development of the industry. All enterprises and institutions in the PV industry chain should actively participate in the standard revision and revision work, standardize product testing and on-site control, and jointly make positive contributions to improving the quality and competitiveness of China's PV products. At this annual meeting, PV companies are particularly concerned about the background of the “double-reverse” incident in the United States.
