Path-Q Solar

How do export rates affect the value of the electricity my panels send to the grid?

Answer

Export rates determine the compensation for surplus generation; when exports are paid less than retail electricity, using solar on-site or shifting it with storage generally has greater value than exporting it.

Key points

  • Separate avoided purchases from exported kWh.
  • Rates may vary by time, tariff, or program.
  • Fixed charges may remain regardless of exports.

What it depends on

  • Utility tariff
  • Hourly production and consumption
  • Storage and self-consumption

Risks and trade-offs

  • Low export value can make oversizing unattractive.
  • Rules may change or have eligibility limits.

Information you may need

  • Current tariff
  • Export rate and caps
  • Monthly or hourly load profile

Your next step
