Cost reduction potential for c-Si PV modules
The PV module itself accounts for around half of total PV system costs. The continued reduction in PV modules costs is therefore a key component of improving the competitiveness of PV. While c-Si PV is the most mature PV technology, there still exists significant room for reducing manufacturing costs through technology innovation and economies of scale. According to one study (Mehta and Maycock, 2010), both low- and high-cost manufacturers could halve their production costs by 2015. C-Si PV module cost projections for period 2010 to 2015 and the assumed increase in average PV manufacturing plant size required to achieve the cost reductions.
