Solar business in trouble, lithium battery energy storage products into tesla energy storage development pillar

Since 2015 energy storage products Powerpack, tesla in the past few years more and more large storage projects.

foreign media reports, on July 30, tesla announced to launch a new type called Megapack large energy storage battery pack, can replace the overload in the local power grid load's electricity & other; Peak & throughout; Power plants.

tesla said, Pacific gas and electric company ( PG＆E） Will be deployed in the Moss Landing in monterey bay, California, a few Megapack, this is California utility companies plan to install more cost-effective energy storage solution of one of the four locations.

tesla will provide fully assembled for electric Megapacks, including & other; Battery module, bi-directional inverter, the thermal management system, AC main circuit breaker and controller, and many other parts & throughout; 。 At the same time, the device also includes a set of software system developed by tesla, used to monitor the whole equipment storage and commercial operation.

Megapack takes up the space is decreased by 40%, need only one over ten of the parts, and assembly speed is 10 times as much as other alternative energy storage solutions.

tesla said, each Megapack can store up to 3 MWH energy at a time, and can be more than enough in series with the Megapack can create a capacity of more than 1 GWh storage systems, called enough & other; San Francisco throughout every family with 6 hours of power &; 。

in fact, at the time of the solar panels business in trouble, lithium battery energy storage products became the mainstay of help tesla maintain energy storage sales development.

since 2016 acquisition of SolarCity, tesla in the second quarter of 2019 the number of traditional solar panel installation is less than the other quarters. （ This is the minimum installation rates SolarCity since 2013. ） Tesla closed in early 2018 a dozen solar installation center, and also out of the Home Depot to sell solar panels in deal, and give up the SolarCity once owned industry leading position.

in 2019, according to tesla's first-quarter results, in the first quarter loss of about $700 million, compared with the same period in 2018, energy storage and solar energy business revenue fell 21%, amount of solar energy systems are from the same 2018 mw, 74 mw fell to 47, 36% decline.

according to the second quarter, tesla Powerwall and Powerpack device volume hit a record high, in the second quarter growth was 81%, and the device for 415 MWh.

even needs to meet the rapid growth of the production of the Model 3, tesla in the whole from 2018 to early 2019, have had to scale back its deployment Powerwall and Powerpack product quantity, which hindered the further development of tesla lithium battery energy storage business.

however, science and technology innovation has changed all that. Recently, duke university and Texas state university researchers have developed a can 3 d print almost any new method for the shape of the lithium ion battery.
