Microsoft's John MathenyMatheny (right), joined by Mountain View City Council member Greg Perry (second from right), gets set to turn on the software giant's solar panel system.
Solar panels were installed on four of the five buildings on the campus, a system that Microsoft calls the largest of its kind in the area. The solar electric system, composed of 2,288 tiles dispersed on the roofs of the four buildings, generates 480 kilowatts at peak capacity, or roughly 15 percent of the total daily power demand. That's enough energy to power 500 homes.
"It's not about the money. It's the right thing to do," said Matheny.
