How the calculator works.
Single-Powerwall installs start at $16,200 all-in. Tesla hardware is approximately $8,200 per Powerwall. Tesla-certified design, gateway, install, and permits make up the rest.
Each additional Powerwall scales the cost by approximately $11,000 to $13,000. Three-unit installs for large homes typically land in the $38,000 to $45,000 range.
Powerwall 3 ships with a built-in solar inverter. New solar + storage installs save on hardware by skipping the standalone inverter. Existing solar arrays connect via AC coupling.
California's SGIP rebate and Arizona utility-specific battery rebates can take a meaningful slice off the install. We walk through eligible rebates as part of the quote and handle the paperwork on every install.
