Cheapest Electricity Plans for Solar Households in Australia
With over 3.6 million rooftop solar systems in Australia, choosing the right plan means balancing feed-in tariffs with usage rates. The cheapest plan for a solar household isn't always the one with the highest feed-in tariff.
What matters for solar households
- Usage rate — what you pay for grid electricity (evening, night, cloudy days)
- Feed-in tariff — what you earn for exported solar (typically 5–12c/kWh)
- Supply charge — fixed daily connection fee ($0.80–$1.40/day)
- TOU windows — time-of-use plans can reward solar self-consumption
Frequently Asked Questions
What is a good solar feed-in tariff?
In 2025–26, competitive feed-in tariffs range from 5–12c/kWh depending on your state. Queensland and SA tend to offer lower FiTs due to solar saturation, while NSW and VIC can be higher.
Should I focus on feed-in tariff or usage rate?
For most solar homes, the usage rate matters more. You still draw from the grid in the evening and on cloudy days. A plan with 2c/kWh lower usage rate saves more than one with 2c higher FiT in most cases.
Do all plans support solar?
Most residential plans accept solar exports, but the feed-in tariff varies widely — from 0c to 12c/kWh. WattLite shows the FiT for each plan so you can compare accurately.
