I would like to install a 1 MW solar farm in the US.  Where should I
install it?  What state should I install it?  How much could I expect
to get per kwh for the power I produce?

I paid about $0,000 for my 5KW system (504 sq. ft.of panels and two 3KW
inverters) operating in conjunction with Pacific Gas & Electric in the San
Francisco Bay Area. It's on a south facing garage roof with 4 in 12 slope.
You're talking about a system that's 200X the size of mine, or roughly 2.52
acres of panels. In my location we have some days of  rain, clouds, morning
fog, but mostly sunny days. Because of surrounding civilization, there is
dust in the air and the panels get grimy. I don't know if a desert location
would be any better for keeping them clean and reap a few percent
improvement in output.

The panels produce less power when the weather is hot, so a location that
gets as warm as 120deg F in the shade would suffer from high temperature
inefficiency. I see a 5% drop in a day's Wh total just due to a day's
average temperature change from 69 to 92 deg F.

I get $.28372 per KWh I return to PG&E from noon to 6:00pm and I pay
$.07664 per KWh all other times from May1 to October 31. The other half of
the year, I get $.10472 per KWh from noon to 6:00pm and pay $.07966 per
KWh all other times. If your location is far from a city, you might not get
the high-use differential in KWh price that I get. I also believe this
two-tier arrangement is no longer available - - it's now a 3-tier adaptable

In the three years my system has been operational, it has produced 17,720
KWh, but I have shading problems from neighbors trees such that my yield
would be 25% higher if the shading were absent. Good luck!

Is California the only state of America that has policy to encourage
solar energy application?

This reference may not be up to date.  Stimulus incentives are in the
works and may help.
