Currently, the major challenge for the solar PV market is adequate procurement of solar grade silicon.

The planned capacity increase in polysilicon production in the coming years is expected to drive solar PV cells output capacity higher. Therefore, the outlook of solar PV market in the next few years largely depends on availability and pricing of polysilicon.

Germany, Spain, Japan and the US dominate the worldwide solar PV market with more than 85 percent of the cumulative installed PV capacity. A key reason for high growth in these countries is the active role adopted by their governments in providing subsidies to the solar industry.

Increasing popularity of "green" energy, rising electricity costs and emergence of more efficient solar PV technologies.
