By 2020, solar
technologies could account for a significant portion of global power
generation, helping economies and businesses guard against rising energy costs
and the impact of climate change. However, finding opportunities to further
reduce the cost of solar technologies will be key to unlocking this potential.
Because polysilicon, the primary raw material used by solar module manufacturers, is the single largest cost in the solar supply chain, it represents the most significant opportunity for cost reduction. Over the next several years, new lower-cost methods of polysilicon production will commercialize, providing the solar industry with a more affordable source of raw material.
In turn, these cost improvements will trickle
down throughout the solar supply chain, accelerating the adoption of solar
energy around the world and helping the industry realize its global
potential.
