Powerwall is a Lithium Ion battery that charges using excess electricity generated from solar PV panels, or when utility rates are low, and powers your home in the evening. This enhances solar functionality and reduces energy costs.

Tesla Powerwall is completely automated, it installs easily and requires no maintenance. Each Powerwall has a 13kWh energy storage capacity, sufficient to power most homes during the evening using electricity generated by solar panels during the day.

Powerwall integrates with solar to store excess energy generated during the day and makes it available when you need it, minimizing reliance on your utility.

On darker days, especially during the winter months, solar PV may not charge the Powerwall to it’s capacity and you can use off-peak cheap rate tariff, this allows you to charge your Tesla powerwall at off-peak rate and then use the stored power during on-peak times to further enhance your savings
