Driven by the development of the photovoltaic industry, China's solar energy equipment (mainly crystalline silicon solar cell production equipment) has grown substantially in 2010 on the basis of rapid recovery in the second half of 2009. In 2011, driven by the localization of key equipment and the launch of new equipment with high efficiency and low energy consumption, China's solar energy equipment will continue to maintain its rapid growth.
The sales revenue of major domestic photovoltaic equipment manufacturers has grown rapidly
According to the statistics of 16 major solar cell equipment manufacturers in China, the sales of solar energy equipment reached 5,107 units in 2010, and sales revenue reached 3.68 billion yuan, which was 63.1% and 67.3% higher than 2009 respectively. China's 16 major solar cell equipment manufacturers all produce crystalline silicon solar energy equipment, of which sales revenue of crystalline silicon material growth processing equipment reached 2.64 billion yuan, an increase of 81.2% year-on-year; sales revenue of crystalline silicon solar cell chip manufacturing equipment reached 1.04 billion yuan. Increased by 40% year-on-year. In 2010, the export value of solar equipment from 7 solar equipment manufacturers reached 89 million yuan, an increase of 376.7% year-on-year. China's crystalline silicon solar equipment has already begun to go abroad and is recognized by foreign users.
This year, China's sales of crystalline silicon battery equipment will increase by more than four percent.
1. Despite the current increase in photovoltaic product inventories due to European subsidies for photovoltaic major markets, the fundamentals of the photovoltaic market have not changed. The downward adjustment of downstream product prices has been gradually transmitted to the upstream silicon materials, which has further reduced the application cost of photovoltaic products and is one step closer to real market application.
Recently, the European Photovoltaic Industry Association (EPIA) stated that in 2011, the global solar energy market will continue to see strong growth. From an optimistic perspective, the new installed capacity of global PV modules will reach 21.145 GW in 2011, compared with last year. It will increase by 27%.
As the on-grid electricity price of photovoltaic power generation gradually approaches the thermal power grid price (to reach 1 yuan/kWh in 2012), China's photovoltaic market will also expand rapidly. Recently, in the "12th Five-Year Plan for Photovoltaic Power Generation" compiled by the National Development and Reform Commission's Energy Bureau, the domestic PV installation target in 2015 was revised from 5GW to 10GW. By 2020, the target will be revised from at least 20GW to at least To 50GW.
2. The continued expansion of the photovoltaic market has led to the development of crystalline silicon solar cell equipment in China. According to the statistics of the five major companies in the first quarter, sales of solar equipment have doubled from the same period of last year. Two of them estimate that sales of solar equipment will exceed RMB 1 billion in 2011, and another three companies will have sales of solar equipment in 2011. Will be close to or exceed 500 million yuan. It is expected that sales revenue of major crystalline silicon solar cell equipment manufacturers in China will increase by 40% to 50% in 2011, and total sales revenue will reach 5 billion yuan.
Domestic crystal silicon solar production line equipment will be more complete
In 2011, China's major crystalline silicon solar equipment manufacturers will have a number of new products entering crystalline silicon solar cell production lines. These new equipment include: 800 kg of polysilicon ingot furnaces, 8 inches of 150 kilograms of high-efficiency, low-energy-consuming fully-automatic single crystal furnaces. Two kinds of domestic equipment can further reduce the unit energy consumption and cost of crystalline silicon materials.
Several key equipments such as silicon multi-wire saws, continuous wet-process multi-crystalline texturing equipment, fully automatic printing presses, and fully automatic rapid sintering furnaces have been used in the past. Now domestic equipment has made breakthroughs, even though it is more expensive than imported equipment. There is still a certain gap in productivity, stability, etc., but trials have begun on small-volume production lines for users.
The introduction of a new generation of tubular diffusion furnaces, high-throughput tubular PECVD, and automatic high-precision solar cell test and separation equipment that incorporates more advanced process technologies will further expand the market share of related domestic solar energy equipment. The cost advantage has been strengthened once more.
The industrialization of these new equipment for domestic solar cells has not only improved the overall equipment capacity of the domestic crystalline silicon solar cell production line, further reducing the cost of the construction line, but also due to technological advances, the production efficiency of the battery line, and the photoelectric conversion efficiency of the product. Both the yield and the yield have been improved, which has reduced the production cost of the solar cell and made the cost-effectiveness of the entire crystalline silicon solar cell line production line.
Timely production of advanced production technology in new equipment
1. The development of domestic crystalline silicon solar cell equipment is not balanced enough
From the perspective of the entire crystalline silicon solar energy production industry chain, domestically produced monocrystalline silicon growth furnaces, polycrystalline silicon ingot furnaces, wire cutting machines, single crystal trough cleaning/textile machines and other equipment have approached or reached international advanced levels and can basically meet The needs of the industry can replace imported equipment and the current market share is relatively high.
Diffusion furnaces and PECVD, currently used in a large number of domestically produced equipment, are tubular. As they can meet the requirements of the production process and the equipment is cost-effective, the market acceptance of these equipments is also high. With the development of process technology, increase of wafer size, and increase of labor cost, continuous equipment more suitable for complete line automation should pay attention.
The key equipments such as domestic multi-wire saws, automatic screen printing machines and rapid high-temperature sintering furnaces have just started trials this year and look forward to more comprehensive breakthroughs, further narrowing the gap with international advanced equipment, and completely breaking the bottleneck of key equipment in the industrial chain.
2. Thin film solar equipment basically relies on imports
At present, the production of amorphous silicon thin-film solar cell equipment, the battery panels are mostly about 2 square meters, in the key equipment performance, stability and automation and imported equipment there is a big gap between the price is difficult to compete with the crystalline silicon solar cells, and Large-size amorphous silicon thin-film solar cell equipment basically relies on imports. Compound semiconductor thin film solar cell equipment, China is still blank.
3. Grasp the innovative development of equipment, accelerate the reduction of the cost of the battery and increase the conversion efficiency
At present, most of the domestic crystalline silicon solar cell production equipment is transformed from the original semiconductor discrete devices and integrated circuit devices. To reduce the production cost of the solar cell, the device must improve the technical performance and automation, reduce consumption, and reduce emissions as a development. The goal of new equipment. In order to improve the efficiency of the conversion of the solar cells, equipment manufacturers should closely integrate with the cell-chip production plants to materialize advanced production processes in new equipment in a timely manner so that the domestic-made devices will develop from generation to generation.
