With 2019 coming to an end in less than four weeks, Tesla Chief Executive Elon Musk wants to make sure that anyone who has bought a Tesla will get their car in time before the federal tax credit for electric vehicles expires.

That’s the sentiment coming from an email that Musk is said to have sent to Tesla employees outlining the company’s most-critical priorities before the end of the year. According to the Electrek news blog, which is heavily focused on Tesla and the electric car industry, Musk let Tesla employees know what is expected of them over the next 26 days.

“The first [priority] is making sure all cars are delivered to their customers before end of year,” Musk said in his email to employees, of which Electrek said it had obtained a copy.

Getting those cars to buyers is critical so that they can reap one of the benefits of buying a Tesla–a federal tax credit for purchasing an electric vehicle. And there may be a sense among Tesla buyers that getting some kind of a tax credit is better than getting nothing at all.

Tesla customers will be able to get a tax credit of $1,875 on their purchases, but only if they take delivery of their vehicles by Dec. 31. The credit, which had been $7,500 a year ago, was cut in half on Jan. 1 of this year, to $3,750, and cut in half again on June 30, to its current $1,875 level. And that amount will disappear entirely on Jan. 1, 2020.

Tesla is looking to finish its current business quarter with at least 100,000 vehicle deliveries. The company set a quarterly record when it delivered 97,000 vehicles in the third quarter of this year.

In addition to stressing the need to complete vehicle deliveries on time, Musk also said Tesla needs to put more emphasis on its solar technology business.

“The second (priority), just as important, is that we immediately increase the rate of solar deployments by a significant degree,” Musk said in his employee letter. Tesla’s solar business had been declining for several quarters, but picked up in the third quarter, as the company said it installed 43 megawatts worth of systems as opposed to 29 megawatts of systems in the second quarter.

In October, Tesla unveiled a new solar roof for home installation, while in August, Tesla announced a new program that allows customers in some states to rent solar panel systems as opposed to purchasing the systems. In California, Tesla solar rentals range between $65 and $195 a month, depending upon the size of a house.

Tesla didn’t return a request for further comment about Musk’s email.
