Any of you down there in the CA. southland--Graham, Mo--know what's
going on with these systems?

Low output clouds solar power in L.A. 
By Kerry Cavanaugh
Staff Writer 
Several of the Department of Water and Power's large-scale solar-energy
projects appear to be generating less than half of the promised
electricity, and experts are investigating whether the shortfall is a
fluke or reflects a broader problem with more than 500 solar
installations citywide. 
A review of six major solar installations showed that the DWP got an
average of only 45 percent of the expected wattage. Two photovoltaic
panels at the Los Angeles Convention Center generated less than 40
percent of design capacity -- just 29 percent from one and 37 percent
from the other. 
"The losses are extremely high with what we're picking up with these six
installations," said Henry Martinez, DWP assistant general manager for
power generation. "Somewhere along the line, we would have expected the
energy we generate from these systems would be a lot more than what
we're getting."
