Agilent Technologies is installing a 1-megawatt solar power system at its Santa Rosa Campus, Silicon Valley / San Jose Business Journal reports.

Sunpower will install its SunPower Tracker, which follows the sun’s movement throughout the day. The system is expected to generate an estimated 1.8 million kilowatt-hours per year, offsetting more than 33 million pounds of carbon dioxide over the next 30 years.

This is equivalent to planting more than 4,700 acres of trees or removing 3,300 cars from California’s roadways, SunPower said.

Agilent will purchase solar-generated electricity for a period of 20 years. At the end of the term, Agilent will have the option to renew the agreement, transfer the equipment to a new site, or buy the system.
