China’s power rationing is widening. So far, the power cuts have expanded to 20 provinces and autonomous regions, including major polysilicon and wafer manufacturing hubs Yunnan, as well as Jiangsu and Zhejiang, where most cell, module, and BOM material manufacturers are based. The power curbs have impacted Tier-1 manufacturers of polysilicon, wafer, and EVA, which have experienced severer shortages since early September.
China’s power rationing

From the middle of September, impacts on the wafer segment slightly went beyond the cell segment, with supply shortages escalating. In the face of wafer shortages, buyers had no choice but accept higher prices after leading manufacturer Longi raised prices markedly in mid-September.

China’s forced cuts to silicon metal production and manufacturers’ reluctant to sell caused silicon metal prices to double to RMB 50-60/kg in the last week of September, pushing up polysilicon costs. In response, some polysilicon manufacturers are reportedly to have raised prices to as high as RMB 230-260/kg. Compared to the pre-power rationing level of RMB 210/kg, the price spike caught buyers in the mid and downstream off the guard.

With polysilicon prices skyrocketing, module orders signed earlier in China and abroad are delivered at a loss. Therefore, quite a few module makers began to halt delivery. The world saw PV plants and module manufacturers either renegotiate prices or postpone projects.

Cell and module manufacturers shut down many lines and lower utilization rates for October over China’s National Day holiday, in the hope to mitigate the impacts of high material prices and shortages. Recent Investigation into cell and module manufacturers found that they have lowered utilization rates to around 50-70% for October.

Just a day before the National Day holiday begins, mono-Si wafer manufacturer giant Zhonghuan published its prices, which surged significantly. This round of price increase adds RMB 0.077-0.086/W of costs to cells. It’s worth noting that Zhonghuan unveiled prices for 182mm wafers for the first time, a response to cell and module makers’ cuts to capacity utilization in October. In the face of shortages and project deferral worldwide, InfoLink will revise down forecast for global demand in the next issue of database report.

With price increases in materials seeing no sign of stopping, leading module makers including Longi, Jinko, Trina, JA Solar, and Risen jointly called for:

1. The government to guide manufacturers to eschew from installation rush expected at the end of the year.

2. Customers to consider postponing schedules for project installation, as supply shortages and decreased utilization rates impact production.

3. Solar industry association to monitor capacity across the supply chain, ensure transparency of market information, and keep supply and demand in balance. If necessary, restrain prices of raw material from rising indefinitely and cut-throat competition.

4. Manufacturers across the industrial chain to ensure healthy development of the solar market from a sustainable perspective.
