The cost is not $3.00 per kwh, but $3.00 per watt of installed capacity. At $3.00 per watt, the panels would need to be in use for 30,000 hours to bring the cost down to $0.10 per kwh, which is in the ballpark of conventional power generation.

If you assume 8 hours per day of sunlight you get 29,200 hours of operation over 10 years. This is why $3.00 per watt is a good price--roughly 10 years payoff with no subsidies.

For anyone interested in the economics of solar and why it is ALREADY economical in many situations, please please PLEASE check out Solar Revolution by Travis Bradford.
