世界での太陽光と太陽熱のコスト比較例など。http://bit.ly/fgwttI QT @J_kaliy: ありがとうございます。単純に熱を直接利用した場合の効率と太陽電池の効率の比較が気になっただけです。

Sounds too good to be true. There must be a catch. There is always a catch. Using molten salt as both the heat transfer fluid and the thermal storage medium sounds great. Problem is, this is somewhat innovative, and the demo plant has only been in operation since 2004. So while six years of performance history is good, it is not the same as the 20+ year track record that trough using thermal oil can point to in the Mojave Desert. So it doesn't have a 20-year track record. Who cares? Well, the investment banks care, and since they hold the purse strings on the funds to build utility-scale solar plants, if they ain't happy, ain't nobody happy. As analyzed in the recently released GTM Research CSP 2011 repor t, the LCOE for CSP and PV are currently pretty close (around $0.12-$0.15/kWh in the U.S. Southwest). The problem is that PV costs are expected to decline faster than par...
