How does Tesla's Powerwall Work?

The Tesla Powerwall is a rechargeable lithium-ion home battery that uses solar power to charge, but unlike most solar power sources, the Powerwall can store solar energy for use during the nighttime. The Powerwall is also a backup electricity power supply for our home.

Because homes typically consume more energy in the morning and evening rather than midday, when solar energy output is the highest, power companies often buy and sell excess energy multiple times a day. This practice increases carbon emissions. Powerwall makes solar energy more practical by allowing you to store it for future use whenever we need it.

The Powerwall works with a solar panel installed on roof and an inverter that converts current from solar panels or a home battery into the alternating current used by your home's lights, appliances and devices. The Powerwall battery stores the excess energy and energy from the utility grid when rates are low.

More important than how the Powerwall currently works (as the technology will likely be updated by the time the Powerwall is readily available to consumers) is what it signals for the future of renewable energy.

Solar energy currently only accounts for half of a percent of the world’s total energy consumption, but the innovations signaled by Tesla, are exciting indicator that the future of renewable energy will be shining brightly, 24 hours a day.

Thank you!
