Exports are net of imports. Equal figures rank the newer date first. Days before April 27, 2026 use PG&E's meter readings where they exist. Every date opens its day or month on the Solar page. Outages count from October 23, 2021, the day after the system was approved to run, and last a minute or more, Go Off-Grid tests left out. The export rankings leave out VPP event days, when Tesla discharged the Powerwalls to the grid for PG&E.
