Mountain View, Calif. ? Internet giant Google revealed plans Monday to install what industry watchers say is the nation’s largest corporate solar project.

Google plans to put about 9,200 solar panels on six buildings at its Mountain View headquarters by next spring. The project, which will be built by EI Solutions, will produce up to 1.6 megawatts of electricity – or enough to supply 30 percent of the campus’ electricity on a hot summer day.

“That would be the record for a solar installation,” said Noah Kaye, spokesman for the Solar Energy Industries Assn.

David Radcliffe, vice president of real estate at Google, said concern about the environment as well as the rising price of electricity motivated the company to go solar.

Radcliffe declined to say how much the solar installation would cost, but said that the energy would pay for itself after 10 years.
