In classic Silicon Valley one-upmanship, Applied Materials, which itself recently got into making solar manufacturing equipment, plans to install over 1.9 megawatts of solar generation capability at its campus in Sunnyvale, California over the next year.

When completed, it's to be the largest solar power installation on an existing corporate facility in the United States, larger than the 1.6 MW system down the street at Google (see Google to install biggest corporate solar power system in the world.)

“As we pursue our strategy to significantly drive down the overall solar cost-per-watt, we feel it is important to lead through example,” said Mike Splinter, president and CEO of Applied Materials
