I'd like to see how the numbers pencil out as compared to a utility scale PV site. My gut tells me that the long term reliability issues would favor the PV. I know what they cost to set up, who knows with this thing. On a strictly installed KWH per $ side by side comparison, I'd bet PV would win. Then throw in the no moving parts simplicity of a PV plant and look down the road 30 years, keep it simple! This has a huge gee whiz factor, PV arrays aren't much to look at, that's why people have bought small wind turbines around here, when it is demonstrable that PV is many time more cost effective, even before factoring in the much greater long term reliability, I deal with this all the time. So much so, I feel that anyone (excluding me of course, my wind turbine is a great wind indicator, and yard art also, plus I know the real numbers) putting up a small wind turbine instead of PV may as well put a big sign on the tower "I'm a dumb ass". PV sounds too good to be true, so simple it goes over the heads of some.
Without letting politics into it, but keeping it technical, the lack of transmission losses on a residential PV system is pretty much zero as compared to a large centrally located plant hundreds of miles away. Just think if we could buy equipment to make our own gasoline, the attitude of the oil companies would be like the utilities attitude toward solar, I'll bet you anything these large salt melting plants are utility financed and promoted. On the other hand maybe they are making power too cheap to meter, what do I know.
