Tesla officially announced its new product, the Powerwall, at Tesla’s design studio in Hawthorne, CA this Thursday. Tesla Energy, Tesla’s new product line specializing in energy as opposed to electric cars, was initiated the same day with the release of the Powerwall.

The Powerwall is a home-mounted battery, installed independent of the power grid and charged by solar panels. Most domestic solar panels power household appliances only while in use, selling unused electricity to the power company and effectively losing that energy for the consumer. The Powerwall aims to change that by storing excess electricity in a lithium ion battery, which uses technology from Tesla’s cars.

The conservation of electricity also manipulates the fact that peak solar panel performance and peak domestic energy consumption are not synchronous, with the former at midday and the latter at evening. By opting to use the Powerwall rather than the grid, users can reduce the strain on power plants and save money by avoiding the augmented energy prices.

“Because now that people are able to store that [unused] energy and then reuse it afterwards, it will probably increase the number of users for solar panels,” Rishi Narain (11) said.

With the introduction of the Powerwall, Tesla is looking to move towards a cleaner and renewable energy source. Rather than solely producing electric cars, Tesla calls themselves “an energy innovation company” as they take steps to a zero emission power generation. This also implies eliminating the consumption of fossil fuels.

The available models are the 10kWh, optimized for power grid failure, and 7kWh, optimized for the use of daily applications. Being relatively small for its power storage, more than one Powerwall can be installed simultaneously to further savings on power generation.

Customers can reserve the Powerwall at Tesla’s website, starting at $3,000 for the 7kWh model and $3,500 for the 10kWh.
