Electric car-maker Tesla Motors has unveiled Powerwall 2, a new version of its residential home battery storage system.
The new energy storage device is cliamed to have twice the energy density and Tesla says that it can seamlessly integrate with multiple levels of the grid.
The new solar rooftop panels have been designed to be act like tiles for easy installation and removing the need for traditional rooftop panels. These rooftop tiles have been developed by SolarCity, a company that Tesla Motors offered to acquire, recently.
According to the car-maker, the Powerpack 2 has 14kWh of capacity, which is enough to power a four-bedroom house with lights, sockets and even refrigerator for a full day. This energy storage system can now be powered using solar rooftop panels.
The Powerpack 2 has been priced at $5,500 per unit and using it could substantially reduce energy cost of an average household.
Big houses and small businesses could buy more than one Powerpack 2 to offset majority of their energy expenses.
At the company’s Gigafactory, the Powerpack 2’s production is scheduled to begin in the coming weeks and installations could take place in December.
Telsa claims that the new powerwall system’s interface and software controls can give utilities and grid operators a higher degree of control, allows for better management of energy, improve grid performance, efficiency and reliability at a lower cost.
Tesla readying to deploy two energy storage projects later this year, whose lithium-ion batteries are now being manufactured at the Gigafactory. The projects include Southern California Edison’s Mira Loma substation and the Kauai Island Utility Cooperative.
The company claims that these two projects will be the largest lithium-ion battery storage systems till date in the world.
According to the company, by accelerating the production of batteries, it could reduce the cost of battery production. The result would that it can sell more batteries than electric cars in the future and lead the way into a new era where energy is produced from 100% renewable sources.
