Tesla will close more than a dozen solar installation centers, with Delaware identified as one of the affected states, according to a Reuters report.

The company would not comment on specifics of the closings. The report was based on Emails viewed by Reuters.

Tesla had merged the former Solar City installation business a couple of years ago as it began to offer batteryback-ups that are powered by solar panels.

The back-ups were seen as a way to spur interest in solar panels on homes. The backup batteries are made at Tesla’s massive complex near Reno, NV.

SolarCity was founded by relatives of Tesla founder Elon Musk. Musk took heat for the merger at the time.

Tesla earlier announced a nine percent cut in staff as the company struggles with ramping up assembly of the mass-produced all-electric Tesla 3, while expanding into other areas such as all-electric tractor-trailer “big rigs.”

The lower-priced Tesla comes with $35,000 to $40,000 price, although the vehicles now being built are said to be in the $50,000 area.

The Trump administration earlier imposed tariffs on solar panels from China, a move that according to some observers will drive up costs of adding panels on homes and businesses.

In 2015, Solar City opened an installation center in Pencader, south of Newark with dignitaries that included Gov. Jack Markell in attendance. Earlier, the company opened an installation center in Seaford.

As shown by the contrast between the bright green SolarCity service trucks and the plain Jane Tesla solar vehicles, the new owner has given the solar business a lower profile.

Tesla also announced it will end a solar sales relationship with Home Depot.
