China's latest move to impose stricter control on PV installations has sent a chilling wave across the domestic market, and in turn created pressure on Taiwan-based solar power supply chain.
The new restrictions are likely to shrink China's new PV installations to 10GWp in second-half 2018, and the entire year's total may reach only 30GWp, slipping 43.4% annually, industry sources noted.
The reduced demand in China has resulted in Taiwan-based solar poly-Si wafer makers seeing production utilization rates plunge to below 30%, the sources indicated.
As demand for high-efficiency solar cells has been much less affected, China makers have devoted more efforts to develop PERC technology to hike energy conversion rate, the sources said, adding Taiwan makers significantly lag behind their China competitors PERC development due to weaker financial support, the sources noted.
Although the Taiwan government is giving policy support for PV power generation in the country, new installation capacity is on;y around 2GWp a year, far insufficient to support the local PV industry's annual output of 5GWp for solar wafer makers and over 10GWp for solar cell makers, the sources indicated.
