This week, latest price trend chart (photovoltaic industry chain July 17)

Solar photovoltaic net news: last week polycrystalline materials low prices were flat in 57 / kg, single crystal materials prices stubbornly high 79 / kg, single, poor polycrystalline materials up to 24 / kg, the cost of single polycrystalline silicon slice difference is about 0. 81 / piece, the market price difference is 1. 31 / ( 3. 15 - 1. 84). , due to the fastest single crystal product line expansion has battery, in the face of the downstream demand side, the upstream expansion speed can't keep up with, make single crystal PERC battery become the biggest part of the recent margin compression. Single crystal PERC price has fallen below 1 last week. 0 per watt, corresponding polycrystalline battery low prices also fall to zero. 84 watt. Single crystal PERC compared with excess margins for polycrystalline cells - 0. 12 yuan/piece. In the short term we think production line variety not quickly adjust to polycrystalline ( Especially the new line) ( Transformation line is likely to cut back polycrystalline) , construction project especially 1 gw production capacity of more than 30 manufacturers will be in the second half of the year on the case, the single crystal of PERC new supply will continue to market. From the demand side, the price of the single crystal PERC components since the beginning of the price of 11 ~ 12%, the margin of stimulus for requirements can dissolve the expansion after inventory contradiction, at the current polycrystalline components below 1. 70 watt, the transfer of demand more and more tend to be more rational and quantitative, at present, a lot of single crystal components around zero. 2 to 0. More than 25 watt, single crystal components exist price expectations, must wait for domestic project started before stabilizing.

'photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, and can meet the needs of different readers. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development,

third, to pay attention to the problem of global warming. The IPCC, presented in the fifth assessment report to 2100 the average global temperature rise control in line within 2 ℃, then give preliminary greenhouse gas emissions on the basis of now by 40 ~ 70%. The IPCC released in October 2018, 8 1. 5 ℃ special report, if you want to achieve the average global temperature rise control in 1. 5 ℃ goal line % of power. In fact the ideal prospect and reality. The current global energy consumption of 1. 3 million tons of standard coal, even though the capital market of renewable energy is popular, such as wind and solar power, but the fossil energy in the whole energy consumption accounted for less than 15%, there is still more than 85% of the energy is coal, oil and gas, so the need for energy revolution.
