Is Solar Worth It in QLD?

Written by Jacob Ramilo, Last reviewed 2026. This guide provides general information only. See how we calculate the estimates.

Queensland receives enough sunlight to support rooftop solar in many areas. Your roof, shade, electricity use and export limit still determine how much you save. More than 1 in 3 Queensland homes already have rooftop solar installations^[1].

Solar Conditions in QLD

STCs can reduce the upfront cost of eligible solar systems.^[2] Queensland's sunny climate can support strong solar generation for many homes.

Feed-in tariffs in QLD vary by region. In South East Queensland, retailers set market rates^[1]. The QCA set the eligible regional Queensland rate at 6.006c/kWh from 1 July 2026, down about 31% from 2025–26^[5]. The rate fell by about 31% from 2025–26. Size your system around the solar you can use, rather than assuming export rates will stay the same.

System Costs in QLD

The cost of a quality 6.6kW system in QLD varies depending on equipment and installer, but STCs can significantly reduce the upfront cost.^[2] As with any state, the final price depends on equipment choices, roof complexity, and installer availability.

Competition among installers in South East QLD is strong, which helps keep prices reasonable. Regional installers may charge a premium for travel, but regional households often have larger roofs and higher energy usage too.

Feed-In Tariffs in QLD

QLD's feed-in tariffs vary by region. In South East Queensland, retailers set market rates^[1]. Eligible regional customers receive the QCA-regulated 6.006c/kWh rate from 1 July 2026^[5]. Check the address and retailer eligibility before using that number: it is not the South East Queensland rate.

Self-consumption matters more than the export rate. Every kilowatt-hour you use directly avoids the retail usage rate. That rate is usually higher than the feed-in tariff^[1].

QLD Solar Installer Standards

To be eligible for STCs under the Small-scale Renewable Energy Scheme, your system must be installed by an installer accredited by Solar Accreditation Australia (SAA)^[2]. It's also worth checking that the components you use are on the Clean Energy Council approved product list^[3]. This protects your STC claim and your warranty.

Fixed Versus Dynamic Export Connections

Energex and Ergon Energy Network offer dynamic connections instead of a basic fixed export limit. A dynamic connection can allow up to 10kW per phase, compared with 5kW per phase on a basic connection. The network can temporarily reduce your exports when needed^[6]. Your system also needs an approved gateway and communication equipment. Ask your installer to list the connection type, export limit and backup limit in your quote.

Worked Example: A Brisbane Home

Consider a Brisbane household using 18 kWh a day with a 6.6kW system costing $5,200 after STCs. The numbers below are for illustration only, based on typical Queensland conditions. For a full breakdown of the assumptions, see our methodology.

The 5c FiT is an editable example. It is not a South East Queensland average or the regional regulated rate. If you use 25% of the solar directly, the annual benefit falls to about $1,032 and simple payback rises to about 5 years. This example does not include temporary export limits.
