The assessment
How it scores, by category
Market position
The data
Capacity guarantee: minimum retained at year 10
The manufacturer publishes two guaranteed checkpoints - 80.0% at year 5 and 70.0% at year 10 - not a full year-by-year schedule. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.
Blackout protection
92 / 100#1 of 32 batteriesGrid-forming (black-start)
The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.
Two things to check
Ask the installer: What usable capacity, backup power and warranted operating conditions will the installed Powerwall 3 configuration deliver?

Strong evidence coverage
18 of 30 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
