Photovoltaic Moore’s Law Will Make Solar Competitive by 2015

May 23, 2008 | Source: IEEE Spectrum

In recent years, global photovoltaic (PV) production has been increasing at a rate of 50 percent per year, so that accumulated global capacity doubles about every 18 months. The PV Moore’s law states that with every doubling of capacity, PV costs come down by 20 percent.

Extrapolate those gains out six or seven years, and PV costs will be below $2/W, making photovolatics competitive with 2004 wind.
