第二代能源墙（Powerwall 2）和太阳能屋顶（Solar Roof）发布会
Join the world’s transition to sustainable energy. Powerwall 2 is a battery for homes and small businesses that stores the sun’s energy and delivers clean, reliable electricity when the sun isn’t shining. Combine Powerwall, solar and an electric vehicle to create a zero emission lifestyle. The sun provides more than enough energy in just one hour to supply our planet’s energy needs for an entire year. Your home can capture this free, abundant energy source through rooftop solar tiles, turning sunlight into electricity for immediate use or storage in a Powerwall battery.
