PVinsights: Upstream Inches Higher Continuously Ahead of China FIT Cut Deadline

Polysilicon price surge continued but at a slower rate this week. Although some major Chinese players are trying to raise the prices as domestic demand kept increasing, Chinese second and third tier players showed less intention in raising the prices as they had some inventory from April to digest. This implies that some suppliers think the prices have been close to the short term peak. Moreover, with the uncertainties of order visibility in June, most suppliers would take conservative strategies to sell their products rather more quantity than higher prices. Therefore, polysilicon inventory level from April slowed down the price surge amid the strong Chinese domestic demands.

Parker Showcases KleenVent line of Closed-Loop Cooling System Add-on Solution for 1.5MW Wind Turbines at AWEA

Designed for wind turbines using a water/glycol cooling sytem, the Parker KleenVent closed loop solution eliminates required maintenance and the related downtime previously required to restore cooling fluid mix levels. KleenVent effectively eliminates water evaporation in the legacy cooling system by containing the water vapor in a closed loop add-on design, and condensing it back into a liquid to maintain a constant water-glycol ratio maintenance to optimize the IGBT cooling systems efficiencies.

PVinsights: Upstream Components Rebound as FiT Deadline Boost China Demand

Amid strengthening Chinese domestic demand, overall polysilicon prices rise for the first time after experiencing a month of severe price reductions. In March, polysilicon prices in China had dropped more than 25% that caused many suppliers to suffer. However, as demand in China reviving in late-April, polysilicon suppliers soon react to increase the prices in order to compensate the loss in the previous month. While in overseas markets, polysilicon price stay still this week, as the demand recovery in overseas market is not as noticeable as in China. However, the downward trend is temporarily creased thanks to the aid of rising polysilicon prices in China. As the result, overall polysilicon prices rebound this week following the gain in polysilicon prices in China.
