According to projections published by Photon Consulting, the fully-loaded cost of manufacturing, R&D, selling, installing, and operating a solar power system for a vertiaclly integrated solar power supplier will likely decrease to $0.12/kWh, or roughly $1.85/watt installed by the year 2010. In sunny areas, the cost of solar could drop below $0.10/kWh. The report, titled “The True Cost of Solar”, puts the current cost of solar (2006 estimates) at $0.25/kWh, or roughly $3.60/watt installed.
