Queensland has more rooftop solar than any other state, but the plan that looks best on a headline feed-in tariff is not always the plan that leaves you better off. In QLD, solar feed-in tariffs (FiTs) change often, some plans cap the higher FiT, and a higher FiT can be offset by a higher usage rate or daily supply charge.
This guide explains how solar FiTs work in Queensland, what to check before you switch, and how Zembl can compare plans for homes and businesses so you can pick a plan that actually suits your usage and export profile.
How solar feed-in tariffs work in Queensland
A feed-in tariff is the amount your electricity retailer credits you for unused solar energy you export to the grid. Your bill is usually a mix of:
- Solar credits for exports (FiT)
- Usage charges for electricity you import from the grid (c/kWh)
- Daily supply charge (c/day)
- Other fees and adjustments depending on your meter and tariff structure
Most QLD solar households get the most value by increasing self-consumption, using solar during the day, and then choosing a plan that is balanced across FiT, usage rate and supply charge.
Energex vs Ergon: why your QLD network area matters
Queensland has two main distribution network areas for most customers:
- Energex: South East Queensland
- Ergon Energy Network: regional Queensland
South East Queensland (Energex network)
In South East Queensland there is generally no regulated minimum FiT. Retailers set their own FiT rates and plan structures, which means offers can move quickly and can vary a lot between retailers.
Regional Queensland (Ergon network)
In regional Queensland, the Queensland Competition Authority (QCA) sets a minimum FiT that eligible customers must receive. Retailers can pay more than the minimum, but they must meet the minimum.
Because minimums and eligibility can change, it is important to confirm your network area and whether your meter and connection qualify.
What “best” really means when comparing QLD solar plans
Search results often focus on the highest advertised FiT. A better approach is to compare the whole plan based on how you use energy.
1) Your daytime usage vs your exports
If you export a lot and use little during the day, FiT matters more. If you use plenty during the day, your usage rate and any time-of-use structure can matter more than a slightly higher FiT.
2) Supply charge and usage rate trade-offs
Some plans offer a higher FiT but increase the daily supply charge or import rates. A quick sense check is to estimate your annual position:
- Estimated annual import kWh × import rate
- Minus estimated annual export kWh × FiT
- Plus supply charge × 365
Zembl can do this comparison for you using your bill data so you are not guessing.
3) Tiered FiTs and export caps
Common structures in QLD include:
- Single rate FiT: same rate for all exports
- Two-tier FiT: a higher FiT for the first X kWh per day, then a lower FiT after
- Promotional FiT: boosted FiT for a limited time, then reverts
These structures can be good or bad depending on how much you export. Always check the plan fact sheet or contract terms.
4) Time-of-use and controlled load considerations
If you are on a time-of-use tariff, your import cost can change by time of day. If you have controlled load (for example, hot water), that rate can also affect the real value of a plan. The best solar plan is often the one that matches your tariff setup, not the one with the highest FiT headline.
How to maximise your solar value in QLD
Even a strong FiT rarely beats the value of using your own solar. Practical steps that often help include:
- Shift usage to the middle of the day: dishwashers, pool pumps, laundry, and business loads where possible
- Review your plan at least yearly: FiTs and retail rates change frequently
- Check your meter and tariff: plan eligibility and pricing depends on your meter type
- Consider batteries where suitable: batteries can lift self-consumption, but they are not always the best ROI for every site
Solar feed-in tariffs for QLD businesses
For businesses, the best-fit solar tariff depends heavily on operating hours and load profile. Many businesses consume most power during the day, which can make solar extremely effective even with a modest FiT. Key business considerations include:
- Demand charges and how solar affects peak demand
- Interval data availability for a more accurate comparison
- Multi-site portfolios where a blended procurement strategy may be cheaper
- Network tariff selection and whether your tariff still matches your post-solar usage shape

Frequently asked questions
What is a good solar feed-in tariff in QLD?
A good FiT depends on your plan structure and your import rates. In many market offers, FiTs commonly sit in a single-digit to low double-digit c/kWh range, but the overall plan value depends on supply and usage charges, caps and conditions.
Can I switch retailers if I have solar?
Yes, most solar customers can switch retailers, and your electricity supply will not be interrupted. You will want to confirm your meter type, network area and any plan conditions before switching.
Is the highest FiT always the best plan?
No. Higher FiTs can be offset by higher import rates or daily supply charges, or may be limited by caps or promotional periods. Comparing the whole bill outcome is more reliable.
How often should I review my solar plan?
At least once a year, and any time your usage changes, for example after installing air conditioning, switching business hours, adding an EV, or changing household size.
