According to the statistics, before October, 2009, there are about 50 companies, which are constructing , expanding, or preparing to construct the production line of multicrystalline (poly-crystalline) silicon in more than 20 provinces in China. The scale of the construction for multicrystalline (poly-crystalline) silicon is 50,000 tons to 100,000 tons.
Regarding the wind power, there are about 70 manufacturers of wind energy now for just several years in Chna. But in fact the demands for wind power in the market of China, the capacity of the first 3 manufacturers are enough fully. That means other 67 manufacturers can't find enough demands of the market for their wind power.
But this is not the most serious problem these companies of renewable energy face.
This biggest problem is off-grid (stand-alone) for these clean energy (solar power, wind energy).
