Therefore, the future of photovoltaic equipment will develop around the following four points:
1. Silicon material purification equipment
The serious shortage of silicon materials has not been fundamentally reversed in the near future. A dozen high-purity silicon production projects that have been started or have actual implementation actions in China require a large amount of domestic equipment support to reduce production costs, and thousands of tons of production equipment are urgently needed. Break through and provide a lot.
2. Large size silicon wafer processing equipment
Most of the current domestic 125mm × 125mm silicon wafers are produced by using a 6-inch single crystal furnace. In order to meet the needs of 156mm × 156mm cell production, it is necessary to use an 8-inch single crystal furnace, but the production cost will be much higher. Silicon wafers produced by polycrystalline ingot casting are unacceptable to battery companies. Therefore, the 156mm × 156mm silicon wafer for photovoltaics will be turned to polycrystalline silicon wafers, and the polycrystalline silicon ingot furnace will be used for production, which will greatly increase the demand for related ingots, cutting and other production equipment.
3. Thin film solar cell production equipment
In order to further reduce the battery production cost and improve the battery conversion efficiency, the research of crystalline silicon thin film solar cells is changing with each passing day, and the development of amorphous silicon thin film solar cells is also advancing rapidly, which provides unlimited development space for the development of related process equipment.
4. Photovoltaic data collector
At present, it is mainly used in some small and medium-sized power stations. Large-scale photovoltaic power plants mainly use industrial computer to carry out local monitoring of power stations. The proportion of network monitoring of photovoltaic power plants is still not high, mainly because enterprises do not pay much attention to after-sales. In the management of photovoltaic grid-connected inverter manufacturing enterprises, the product development department has a strict demand for these monitoring data. However, sales and engineering personnel are not very concerned, which leads to less installation of PV network monitoring. At present, there are nearly 100 PV power plants that are remotely monitored on the green power grid, and the growth rate is increasing by 50% per month.
Trend of total installed capacity of photovoltaic equipment in China
China's PV equipment installed capacity will reach 4GW in 2012. The Chinese government has set the target for photovoltaic power generation capacity in 2015 to 21GW, and the solar industry is expected to prosper.
In 2012, China's installed capacity of photovoltaic equipment will exceed 4GW. According to an analysis by the British research institute IMS Research, it is expected that the prosperity of China's solar industry will bring "great business opportunities" to suppliers of the photovoltaic industry. China's latest five-year plan for the photovoltaic industry revealed that China's national regulatory and reform agency, China's National Development and Reform Commission, has increased the installed capacity of photovoltaic power generation in 2015 from 15GW to 21GW.
