…if you're on NEM 3.0.

Rough estimate — we don't have your utility's rates yet, so this uses a California-average rate set.
You're grandfathered into a strong export rate, so the export-vs-charge gap is small. Sundial still automates solar + peak-avoidance charging, but we'd rather be straight with you: the killer math is NEM 3.0.
Even at this usage, Sundial keeps more of your own solar in the car — free to use.

We'll pull your utility's real published rates — your actual local number, not a state average.

Heads up: on NEM 1/2 your export rate is close to retail, so the savings here are drastically smaller. Sundial still helps with peak avoidance, but the big win is NEM 3.0.
Solar installed before April 2023 in CA is usually NEM 2. We'll compute as NEM 3.0 — your estimate says so.
