Tesla’s Powerwall Battery

Tesla’s Wall-Mounted Battery.

Tesla has developed a wall-mounted electric storage battery called Powerwall.  Tesla is well-known for high-technology end electric cars.  The development of the Powerwall moves them into the energy storage business.  The battery is a rechargeable lithium-ion battery that mounts on the wall.  There will be a 7 kWh and 10 kWh option for residencies.  There are plans for larger units that could be marketed to utilities.

The National Rural Electric Cooperative Association (NRECA) concluded that the systems appears to be a significant step forward.  The batteries are technically intriguing due to their thin form factor and higher than typical battery voltages which result in improved efficiency.

In this article I will briefly touch on Tesla’s Powerwall battery, and how I think it may (or may not) change the way power is stored.

Their new battery can store electric energy for later use.  The battery can allow a house with solar panels to store energy generated.  The batteries could also be interconnected with the local utility grid.  This would allow it to be used for standby power which could be utilized during an outage.

The buzz is that the batteries will be priced between three and four thousand dollars.  This does not include installation and any additional equipment for connection to solar panels.  The batteries will come with a ten year warranty as well.

I have to admit that I do not know how well these batteries will be accepted.  After all, a standby generator is much more cost-effective.  Plus, solar installations typically include batteries to store generated energy that is not immediately consumed.  Even if I could afford a Tesla, I’m not sure I would be running to buy a Powerwall anytime soon.

I’d love to know what you think.  Do you think the Tesla Powerwall will be a hit with the masses?  Feel free to leave a comment in the section below!
