The electric carmaker, Tesla, is downsizing and cutting its workforce, and among those targeted are residential solar operations in Arizona. 

According to a Reuters report from last week, Tesla is closing more than a dozen solar installation centers in nine states, including Arizona.

Three internal company documents and seven current and former Tesla solar employees provided the news service with the information. According to employees, transfers are in order for some of those who work for a closing plant.

California, Maryland, New Jersey, Texas, New York, New Hampshire, Connecticut and Delaware were the other states with offices that would be shut down, according to an internal email.

In 2016, Tesla bought SolarCity’s two Phoenix locations for $2.6 billion. Today, however, it is still unknown which specific locations will be closed.

In an interview with to Ars Technica, a Tesla representative said that 9 percent of the workforce will be reduced, something employees have known about for months.

Tesla is also ending its partnership with Home Depot, the company that helped it earn nearly half of its residential solar sales.

The Tesla company and its flamboyant head, Elon Musk, have not profited from the company in 15 years of business, only posting to quarterly net profits ever.
