Do not convert this label into a single permanent cents-per-kWh assumption. Open the official source below and verify the tariff that applies to the account and interconnection date.

What to verify before using a savings calculator

  1. CHECK 1

    Confirm legacy NEM status versus the Solar Billing Plan.

  2. CHECK 2

    Use the current residential time-of-use tariff rather than a flat retail rate.

  3. CHECK 3

    Model hourly export credits and evening household consumption.

  4. CHECK 4

    Compare solar-only and solar-plus-storage scenarios using the same load assumptions.

Verify against the primary source
