SolarCity announced its move into a vast new Roseville, California office to accommodate its growing local staff. The company currently employs more than 450 in sales, project management, marketing, design and IT roles at the location, and SolarCity expects to boost its local workforce by hiring at least 300 additional employees to the inside sales team in 2015.

The bulk of the company’s national inside sales team, which provides virtual solar energy consultations and services to customers in 16 states, is housed in Roseville. The new 60,000-square foot facility at 1000 Enterprise Way consolidates employees from five disparate offices in neighboring Granite Bay where Paramount Solar, acquired by SolarCity in 2013, was previously located. More than 250 employees also work at SolarCity’s Sacramento operations center, which provides solar installation services to the Sacramento metro area.

“The local success and growth of companies like SolarCity shows that the City of Roseville has what it takes to help foster a new economy,” said Roseville Mayor Carol Garcia. “The hundreds of jobs that SolarCity has brought to our community simply did not exist less than a decade ago, and we are delighted to see our citizens benefit from this evolution.”

SolarCity is the largest solar employer in the United States, with more than 10,000 employees across the country.
