Solar Cells for Giants
We reported the plans a few months ago, and now it's happened. The San Fransisco Giants' stadium has just been fitted with 590 solar panels, produced by Sharp, that are outputting up to 120-kilowatts of electricity. Sports fields are perfect locations for solar panels; they have huge roof areas.
They also have unusual power consumption habits - they consume huge amounts of power once or twice a week, but then sit almost idle the rest of the time. These fluctuations are also yearly seasonal, because out of season the parks aren't used as much.
This means that a large solar array is best used to feed power back into the grid, making money which can be used to pay for the huge power bills from the peaks. The cells won't provide any power to the club at all - it will all be used by other consumers.::Engadget
