Generation Meter

A generation meter records the total amount of electricity your solar panels produce, and is required to receive payments under the Feed-In Tariff or some SEG contracts.

Generation Meter explained

A generation meter is an electricity meter installed as part of your solar system that measures the total amount of electricity your panels generate — regardless of whether that power is used in your home or exported to the grid.

Under the old Feed-In Tariff (FIT) scheme, generation meter readings were submitted quarterly to your FIT licensee, who paid you a generation tariff for every kWh produced (typically 3.5–15p/kWh depending on when you registered). If you have a pre-2019 FIT contract, you still submit generation meter readings regularly.

Under the current Smart Export Guarantee (SEG), most tariffs only pay for exported electricity — a separate export meter (or your smart meter's export register) records this. A generation meter is not always required for SEG, but some FIT contracts that transitioned to SEG still require readings.

How to read your generation meter:

  • It's usually a white box with a digital display, mounted near your inverter
  • Records cumulative kWh from system installation
  • Some modern inverters have an integrated generation meter in their display or app

If you're buying a house with existing solar panels, ask for the generation meter reading history — it tells you how well the system has actually performed over its lifetime.

How this affects your solar decision

Keeping track of your generation meter readings helps you verify your system is performing as expected and claim all eligible payments. Use the Solar Savings Calculator to track your expected vs actual generation.
