Understand export caps

When your solar system generates excess electricity, the leftover energy gets exported back into the power grid and we pay you for it.

When your solar system generates excess electricity, the leftover energy gets exported back into the power grid and we pay you for each kWh you export.

On our business Solar Boost plan, an export cap sometimes applies. This will affect the price you get for the excess energy (your feed-in-tariff) that you produce.

For every kWh you export beyond your cap, your feed-in tariff (FIT) goes back to our standard retailer feed-in tariff rate at that time, instead of the higher one advertised on our Solar Boost plan.

How is an export cap calculated?

We generally refer to it as a daily cap, but we average it out over your billing period. It’s calculated by multiplying your daily export cap by the number of days in your billing period. Here’s an example:

  • Let’s say your daily export cap is 14kWh and you’re billed quarterly (every 90 days)

  • We multiply 14 (your daily export cap rate) by 90 (days in your billing period)

  • Your total cap for that billing period is 1260kWh

That means for every kWh that you export over 1260kWh during your 90-day billing period, you’ll get our lower, standard FIT rate. When you start a new billing period, your export cap will start again.
