Tesla Q1 results and highlights

Energy storage according to Musk

Musk said Tesla is focused on optimizing the operational efficiency of the company for the long term, not for quarterly results. As for the recent automotive Apple rumors, Musk said that he hopes Apple enters the vehicle business.

The energy business occupied much of the attention of the analysts in the Q&A portion of the earnings call.

Musk said that the response for the energy storage products "has been overwhelming." He added that there are 38,000 reservations for the residential Powerwall product and 2,500 reservations for the 100-kilowatt C&I battery.

The CEO said that the company had "sold out through the next year in the first week." Musk said that there had been so many requests for distributors, "We have to triage our response to people who want to be distributors." Tesla suggests that stationary energy demand could be double that of automobiles in terms of megawatts.

Musk said that the 7-kilowatt-hour daily cycling storage unit is more suited to the rate cases and utility policies of Germany and Australia. The CEO said that storage economics in the U.S., with rare exception, are more expensive than power provided via a utility. But, said Musk, that doesn't mean that people won't buy it for the security of backup power.
