What Is The Tesla Powerwall?

Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. Automated, compact and simple to install, Powerwall enables you to maximize self-consumption of solar power generation.



The average home uses more electricity in the morning and evening than during the day when solar energy is plentiful. Without a home battery, excess solar energy is often sold to the power company and purchased back in the evening. This mismatch adds demand on power plants and increases carbon emissions. Powerwall bridges this gap between renewable energy supply and demand by making your home's solar energy available to you when you need it.



Powerwall automatically switches to battery power in the event of an electric company outage, bringing peace of mind to those who live in areas prone to storms or unreliable utility grids.

Elon Musk and his team are planning the first roll out of the new Tesla battries in Australia, the price that is paid in Austrailia for the excess solar power that Austrailian homes generates is lower than the price payed for electricity from the utility grid. Given this rate structure, it is more cost effective to consume your solar power than to sell it back to the utility. By storing your home's surplus power and using it when you would otherwise need to pull from the grid, Powerwall minimizes your net spending.



Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery.
