This was a response to tumbling prices of solar panels, triggered largely by a big increase in polysilicon production capacity.

这个转变反映了对太阳能板的需求减少,也反映了供应量和多晶硅(太阳能板中最重要的材料)供应的增加。
The turnaround reflects reduced demand for solar panels, and also an increase in supply of panels and of polysilicon, a crucial material in many panels.
One problem for the emerging technology is cost, even in the aftermath of a sharp fall in solar panel prices, following a global glut of the main raw material, solar-grade silicon.
