Solar photovoltaic net news: according to the set consulting, new energy research center set bond EnergyTrend new energy network analysis, this week in oversupply of the overall market atmosphere, for the arrival of the off-season, producers are conservative attitude to deal with carefully, each link between the prices will change with the change of the demand continues to drop and the see-saw. Upstream even the slightest, see-saw between silicon wafers is in stable situation, supply side has capacity wheel stop overhaul conveniently can ease the tension between supply and demand, the downstream cell and component inventory accumulation is overmuch, phenomenon, in turn, affects the overall market prices, if you can't undertake appropriate requirements, the phenomenon of price downward revision will be more and more obvious. Looking to the future weeks of supply and demand change, it is difficult to see how optimistic the trend of prices is to be the influence of market supply and demand between the wisdom of the solution.
polysilicon material market prices this week to maintain close to last week, although the overall slowdown in demand, single crystal materials still maintain a strong price, polycrystalline materials is affected slightly down slightly. Picking orders at present already sign completed in succession at the end of last month, production scheduling, domestic manufacturers have allocate appropriate also does not lack of material problem, but the proportion of production of single crystal materials rose month by month, according to market demand for single crystal materials is still more than polycrystalline materials, in the third quarter and overseas companies began to perform routine maintenance arrangement, the expected demand for high purity materials can have influence. The price of overseas by interval to nine. 51 ~ 10. 02 usd/KG, the average down to 9. 68 usd/KG, the global average price down to 9. 38美元/公斤。 Domestic polycrystalline materials fixed interval to 60 ~ 63 RMB/KG, the average price down to 62 RMB/KG, single crystal materials remain unchanged in 74 ~ 78 RMB/KG.
this week silicon market changed little, mainly by slowing the downstream demand, trading attitude is affected. Monocrystalline silicon chip have been influenced by price, but also for both before and after the demand gap is too large to form a price collapse. Polycrystalline silicon slice of the market to maintain the stability of a few weeks before travel down trend. The single crystal 156 in overseas markets. 75 mm the product remains unchanged at zero. 415美元/ Pc, 158。 75 mm the product remains unchanged at zero. 455美元/ Pc, 161。 75 mm the product remains unchanged at zero. 460美元/电脑。 Polycrystalline fixed interval to 0. 244-0. 248 usd/Pc, the black silicon products down to zero. 275美元/电脑。 Domestic monocrystal fixed interval to 3. 00 ~ 3. 11 RMB/Pc, remain unchanged in 3 large size products. 35元/电脑。 Polycrystalline remain unchanged in 1. 87 RMB/Pc, ingot casting remain unchanged in 1 single crystal products. 95 RMB/Pc, the black silicon products remain unchanged in 2. 14元/电脑。
this week battery slice of the market affected by inventory continuous accumulation, loose prices began to decline. In the third quarter of the traditional off-season does affect the overall market delivery speed. At present overseas general polycrystalline cell remain unchanged at zero. 113-0. 127 usd/W, general single crystal cell remain unchanged in the 0. 115-0. 145 usd/W, high efficiency single crystal cell remain unchanged at zero. 155-0. 172 usd/W, high efficiency single crystal cell ( > 21. 5%) Remain unchanged in 0. 148-0. 190美元/ W。

use this form to explain, is a set of string inverter, group and shut off, set of string plus the optimizer, a runtime dc high voltage, a dc high voltage is shut off, set series inverter dc on the runtime and shut off pressure, set of string and shut off the device or to add the optimizer, shut off without dc high voltage, but the runtime is still has a dc high voltage, just out of the anhui province is fire out of the file, I put out the fire when you don't let the fire fighters have life security, but at least solve the shut off in an emergency of the operational safety, if you run very good luck during installation of high pressure will be much smaller, the advantage of the micro inverter is runtime and shut off when there is no dc high voltage. The image below is a cost problem, below the yellow line system, the greater the lower the price, the lower the cost per watt, and shut off the device in which the green line is also add a little money, shut off the machine more expensive, red salt is inverse, it will not change as the system size is fixed, small system with micro inverse is the most simple the most clean, because of the relative cost gap is not so big, in the large system is more suitable for use in industrial and commercial shut off, the optimizer of this type of product, so this picture gives you a choice and price comparison.
'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,
