Therefore, the future of photovoltaic devices will focus on the following four points:
1 silicon material purification equipment
The phenomenon of serious shortage of silicon in the near future is still unable to fundamentally reverse, domestic has started or actual implementation action of dozens of high-purity silicon production project needs a large number of domestic equipment support to reduce the cost of production, kiloton production equipment urgently need to breakthrough and provide a large number of.
2 large size wafer processing equipment
The 125mm x 125mm specifications silicon mostly by 6 inch single crystal furnace crystal pulling production, to meet the needs of 156mm * 156mm cell production, it is necessary to use the 8-inch mono crystal furnace, but the production cost will be much higher than polycrystalline ingot production of silicon, battery enterprises are unable to accept. Therefore, photovoltaic 156mm * 156mm silicon will turn to polysilicon, polysilicon ingot furnace production instead, will pull the huge demand of the ingot, cutting and other production equipment.
3 thin film solar cell production equipment
In order to further reduce the production cost and improve the conversion efficiency of the battery, the research of crystalline silicon thin film solar cell is advancing rapidly, and the development of amorphous silicon thin film solar cell is also developing rapidly.
4 photovoltaic data collector
At present, it is mainly used in some medium and small power plants, and the large photovoltaic power plants mainly use industrial control computer to carry out the local monitoring. PV power station network monitoring is still not high, the main business is not very much emphasis on customer service. In photovoltaic grid connected inverter manufacturing enterprise management, product research and development department for the demand of these monitoring data is more urgent, but sales and engineering staff is not very seriously, which led to the installation of photovoltaic network monitoring less. At present in the green power line remote monitoring of the photovoltaic power plant has nearly 100, and a 50% increase in the monthly growth rate.
Trend forecast of the total installed capacity of photovoltaic equipment in China
2012 China PV equipment installed capacity will reach 4GW above the Chinese government will 2015 PV installed capacity target identified as 21GW, the solar industry is expected to appear in a prosperous development situation.
2012 China PV equipment installed capacity will exceed 4GW. According to Research IMS, UK research firm, the industry is expected to flourish in China's PV industry will be a huge business opportunities". China's latest PV industry's five year plan revealed that China's national development and Reform Commission, China's national development and Reform Commission has been the 2015 PV installed capacity target increased from 21GW to 15GW.
