Solar photovoltaic application CPIA: our key technical index prediction (polysilicon link 2019 - 2025).

As the technology progress and the comprehensive utilization of energy, by the year 2025 is expected to be down to 10. 1 kgce / kg - Si。 Power stations in 2019, the national integrated polysilicon average power consumption has fallen to 70 KWH/kg - Si, flat with the previous year. In the process of comprehensive energy consumption of polysilicon including polysilicon production of electricity, steam, water, etc. ( Polysilicon production process of each link to categorize, energy consumption, measurement and calculation method according to the polysilicon enterprise energy consumption per unit product limit GB29447 - 2012) 。 Future with improve production equipment and technology, system optimization ability increased, the scale of production, etc. , is expected to 2025 and more than 5% of the decline in space. If single furnace output 80% dense material, the reduction of power consumption of about 55 KWH/kg - Si。 Solar photovoltaic (pv) net news: in 2019, the national polysilicon production of 34. 20000 tons, year-on-year growth of 32. 0%. Future as gas ratio continuously optimize big furnace type, regenerative energy storage putting-in-service proactively and stable production, as well as the single crystal manufacturer for trial of the cauliflower, solar energy, reducing power consumption will still showed a trend of declining, to reducing power consumption is expected to drop to 2025 KWH/kg - 45 Si。 Comprehensive energy consumption of polysilicon enterprise average of 12, 2019. 5 kgce / kg - Si。 Phase change heat storage cost but due to the market demand for single crystal pull rods used in dense material increasing, on some measures, such as reduction of power consumption, power consumption on the decline is not obvious, and even increased.

solar photovoltaic network statement: this information is reproduced from the power grid cooperation media or other Internet web site, what are the new energy project solar photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, in the project bidding and parity, China solar energy network, transparent solar glass of state-owned enterprises has become the absolute main force. We from the upcoming release of the 2019 China pv industry development trend of the development route in the following, with readers. As the market demand for single crystal pull rods used in dense material increasing, the 2019 national average polysilicon reducing power consumption from 2018 slightly ascending, 50 KWH/kg - Si, the density of the corresponding material proportion is about 65 - 70%. Released with the new expansion of capacity and technical level of continued ascension, enterprise production comprehensive energy consumption dropped. The current mainstream of polysilicon production technology mainly include chemical hydrogen silicon Siemens method and silane fluidized bed method, solar power grid, solar panels, solar panels, product shape of rod silicon and silicon particles respectively. What new energy projects in particular, CGNPC 603 mw, regenerative energy storage technology in guangzhou development of 410 mw, energy saving of 220 mw, 345 mw, jin can group of people for 200 mw, 190 mw hubei energy group, huaneng 180 mw polycrystalline silicon reduction refers to silicon chemical hydrogen and hydrogen reduction reaction of high purity silicon process, its power consumption including silicon core preheating, sedimentary end insulation, ventilation and so on the electricity consumption in the process of technology. Integrated power consumption refers to the polysilicon products factory production unit consumption of all power, including the synthesis and electrolytic hydrogen making, distillation, reduction, recycling of the waste and hydrogenation of power consumption. The article content is for reference only. But the development of the N type battery will enlarge the market demand of silica particles, once the silicon particles to solve stability, consistency, production scale and product quality problem, does not exclude the silicon particles market share will be rapid growth. Chemical hydrogen silicon Siemens method relatively mature production technology, using this method in 2019 to produce silicon rod accounted for about 97 of the total national output. 5%, will remain the mainstream production technology in the future. This paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information.
