Every solar purchase includes Powerwall, a compact home battery that reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining. You can add additional Powerwall units to your order to further lower your carbon footprint and to prepare your home for power outages.

An integrated battery system that stores your solar energy for backup protection, so when the grid goes down your power stays on. Your system detects outages and automatically recharges with sunlight to keep your appliances running for days.
