One day Solar will be competitive
[T]he US DOE actually tries to calculate the cost of various energy sources using a complicated levelized cost model. Seehttp://www.eia.gov/forecasts/aeo/electricity_generation.cfm. For power plants coming on line in 2017, their nationwide average estimates in $/MWH are:
Conventional Coal: 98
Convenional CC Gas: 66
Solar PV: 153
On average, PV has a ways to go. However, the lowest regional cost of PV is 119, while the highest regional cost of coal is 115 and advanced nuclear is 119.
So there are probably places today where PV is cost competitive. But the market can surely figure this out at least as well as the government.If these numbers are right, it means that we are just now hitting the point where solar power makes economic sense in a few places without any government subsidies. That's pretty amazing, if you ask me. I wonder how many of those places there will be in 7 years...

One thing i never figured out is this, if a Solar Panel cost USD 100,000 but lasts forever i can make power every day and one day in year 37 the amount i saved every month equals USD 100,000. I would like to know how are this numbers today? how many years do Solar Panels can keep running without big maintenance? how much can i recover from the initial cost every year? etc....
