Powerwall 3: Home Energy Revolution

The Powerwall 3 is Tesla's latest home battery, offering 13.5 kWh of usable capacity with a built-in solar inverter -- a first for the Powerwall line. This integration eliminates the need for a separate solar inverter, reducing installation costs and complexity while increasing system efficiency.

With 11.5 kW continuous power output (and 185 kW peak for brief surges), Powerwall 3 can power an entire home during outages, including power-hungry appliances like air conditioners, electric vehicle chargers, and pool pumps. Multiple Powerwalls can be stacked for larger homes -- up to 4 units providing 54 kWh of storage.

Pricing starts at approximately $9,200 before installation. With the 30% federal Investment Tax Credit (ITC), the effective cost drops to around $6,440. Most homeowners recoup their investment within 7-10 years through reduced electricity bills, time-of-use rate optimization, and backup power during outages.

Megapack: Grid-Scale Energy Storage

Tesla Megapack is the company's commercial energy storage product, with each unit storing 3.9 MWh of energy -- enough to power approximately 3,600 homes for one hour. Megapacks are deployed by utilities, governments, and large corporations to stabilize electrical grids and replace fossil fuel peaker plants.

Major installations include the Moss Landing project in California (1.2 GWh), the Victorian Big Battery in Australia (450 MWh), and the Lathrop Megafactory in California -- the world's first dedicated Megapack manufacturing facility, producing 10,000 Megapacks per year. A second Megafactory is under construction in Shanghai.

Tesla Energy's storage division has become one of the company's fastest-growing revenue segments, with deployments more than doubling year-over-year. Megapack demand far exceeds supply, with orders backlogged into 2027. Each Megapack includes Tesla's Autobidder software, which uses AI to automatically trade energy on wholesale markets, maximizing revenue for operators.

Solar Panels & Solar Roof

Tesla Solar Panels: Available in 400W and 425W configurations, Tesla solar panels are designed to integrate seamlessly with Powerwall. Systems typically range from 4 kW to 16 kW for residential installations, with pricing starting around $2.00 per watt before incentives. With the 30% federal ITC, a typical 10 kW system costs approximately $14,000 after credits.

Solar Roof: Tesla's premium offering replaces conventional roofing with tempered glass tiles that contain embedded solar cells. Solar Roof is ideal for new construction or homes needing a roof replacement. Pricing typically ranges from $35,000 to $70,000+ depending on roof size and solar coverage, with the solar portion eligible for the 30% federal ITC.

Both solar products pair with Powerwall for whole-home energy independence. Tesla's app provides real-time monitoring of energy production, consumption, and grid interactions, giving homeowners complete visibility into their energy ecosystem.

Virtual Power Plant (VPP)

Tesla's Virtual Power Plant connects thousands of Powerwalls into a coordinated network that functions like a distributed power station. During peak demand, Powerwall owners can opt in to share stored energy with the grid, earning credits on their electricity bills while reducing strain on the electrical infrastructure.

Active VPP programs operate in California, Texas, Puerto Rico, and parts of Australia. During heatwaves and grid emergencies, Tesla VPPs have delivered hundreds of megawatts of power -- equivalent to a medium-sized power plant -- without burning any fossil fuels. As Powerwall installations grow, VPP capacity increases organically, creating an ever-larger clean energy resource.
