"we are headed for more than 60% over-supply of solar cells in 2009, with as much as 100% excess in 2010."
Not only this but the solar companies that will save the planet are not the low efficiency, high cost ones like ECD that are concentrating on commercial buildings, but clearly the great promise of solar is in companies that are focusing on large scale solar projects and that are combining other technologies like the use of mirrors. So maybe someone here can explain why all the fuss about a company like ENER that has limited potential with its current solar technology. Oh please let's not even get into the miniscule few cents a share in profits after 40 years of trying.

Sorry, the addition of more large scale generators requires reinforcement of the grid, which will be difficult, primarily due to NIMBY. Small distributed generators closer to the power system loads will add stability to the grid and avoid power distribution system losses - the smaller and the closer, the better.
NREL and this report disagree with your assumptions.
The report, “On the Rise: Solar Thermal Power and the Fight Against Global Warming,” concludes that a patch of solar arrays some 100 x 100 miles could power the country. That's slightly more than what’s already been excavated for strip mining for coal, the group notes.
The National Renewable Energy Laboratory has identified the potential for more than 7,000 gigawatts (GW) of concentrating solar power generation on lands in the Southwest -- more than six times current U.S. electricity consumption. When the sun isn't shining, the plants could release stored energy.
