| “In recent years, global 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. In 2004, installing PV cost about $7 per watt, compared to $1/W for wind, which at that time was beginning to stand on its own feet commercially, Last, year, as recently noted in this blog, average global solar costs had come down to between $4 and $5 per watt, right in line with the PV Moore’s law. Extrapolate those gains out six or seven years, and PV costs will be below $2/W, making photovolatics competitive with 2004 wind.” |
