Rebranding and re-imagining existing technologies has been Tesla's forte since it was founded in 2003.  It was Tesla that revitalized the 21st-century electric vehicle market. Since then, they’ve been experimenting and coming up with big ideas for solar energy generation and storage. A complete makeover of residential solar batteries has also been on Tesla’s long list of initiatives, culminating in the recent release of the Tesla Powerwall 2.

Before we delve into the technicalities of the Tesla Powerwall 2, let’s have a look at what a Tesla Powerwall is:

What Is a Tesla Powerwall?

Tesla Powerwall II is a rechargeable Lithium-Ion battery with liquid thermal control. It can store the energy your solar system generates for the evening or emergencies. Tesla is one of the very few companies that make a lithium-ion battery for home energy storage. The best part of the Powerwall is that it's automated, low profile requires no maintenance.

  • The list price offered for the Tesla 2.0 battery is $6,700. When you add the hardware and equipment to the cost, the pricing goes high up to $8,000. Installation costs vary between $2000-4000.


  • In case if you’re considering a solar-plus-storage system battery- a 5 kilowatt (kW) solar energy system costs between $8,500 to $16,000. It entirely depends on where you live and what type of equipment you chose.  


  • Solar Panel economics depends on various factors. It's not just the main solar equipment you’re considering. The installation costs, the battery costs, permit fees, taxes, and electrical upgrades add up to the cost.


How does a Tesla battery work:

Tesla has given their blood and sweat in producing the Powerwall II. Their main focus shifted from manufacturing batteries for automotive to residential. Tesla’s battery is for day to day use at your home. The excess energy in from your solar system’s existing batteries is stored and is usually paired with your home solar system.

When your panels aren’t producing enough electricity, the electricity stored in your Powerwall is utilized. You won't have to worry about buying electricity from the grid.

The process takes place in the daytime usually. The surplus energy is stored in the Powerwall when the sun is up. The electricity stored in the sunniest part of the day then comes into use at night time when the sun goes down.
