What's This?

Today, Elon Musk, CEO and Founder of Tesla Motors, announced a new venture focusing on Tesla solar batteries. The announcement focused on the Powerwall Home Battery, a stationary battery for homes that will help users store solar power without the requirement of a grid.


The Powerwall Home Battery is open for pre-order in the USA and will be available somewhere late summer. The cost of 10kWh batteries will be $3,500 while the 7kWH batteries will cost $3,000. The batteries can be stacked together up to the quantity of nine, and you can use the power according to your requirements.

Tesla has something in store for utility suppliers too. As mentioned in the website, “For utility scale systems, 100kWh battery blocks are grouped to scale from 500kWh to 10MWh+. These systems are capable of 2hr or 4hr continuous net discharge power using grid tied bi-directional inverters.”

The Tesla solar batteries will be able to store power in the dark. They include liquid thermal control systems and software that will help them get integrated to a solar inverter. A continuous supply of 2kWh power can be expected from the batteries.

The battery can be effective at the time of load shifting, and it can provide back-up power, increasing self consumption of solar electricity produced by the home solar panel. The stationary solar battery can be mounted anywhere one wants.

With a peak power of 3kHw and a round trip efficiency >92%, it is expected to provide an efficient electricity solution. The battery comes with 10 years warranty.

Tesla, associated with the cool sedan car in the USA, was planning for so long to be part of the solar power industry.

As reported earlier, the launch was expected to take place this week, so this announcement comes without much glitter.
