Solar Power Installers & Suppliers in Queensland

Choosing Solar Power Installers in Queensland

Queensland (QLD) earns its “Sunshine State” nickname by averaging more than 2,800 hours of sunlight a year, making it one of the best locations in Australia for solar panel installation. Whether you’re building a new home, renovating, or reducing operational costs on a commercial site, the right installer will design a system tailored to your roof, energy profile and budget. This guide covers the essentials so you can compare Queensland solar companies with confidence.

Typical Services Offered

• Site assessment, shade analysis and system sizing
• Grid-connected and off-grid solar PV system design
• Battery storage specification and installation
• Inverter selection and wiring
• Monitoring, maintenance and system upgrades

Licensing & Accreditation

In Queensland, anyone who performs electrical work on a solar PV system must hold an Electrical Work Licence issued by the state and be accredited by the Clean Energy Council. The CEC accreditation confirms the installer meets Australian Standards and is eligible for federal Small-scale Technology Certificates (STCs), which can reduce upfront costs.

Indicative Costs & Incentives

Pricing varies with system size, roof complexity and component quality. As a ballpark, a 6.6 kW grid-connected system in South-East Queensland can range from $5,000–$8,000 after STC rebates. Regional locations may incur higher travel and logistics fees. Additional savings may be available through:

• Feed-in tariffs from your energy retailer
• Interest-free loans or grants from local councils
• State battery rebates when bundled with storage

Questions to Ask a Solar Supplier

1. Are you CEC-accredited and appropriately licensed in QLD?
2. How many systems of this size have you installed locally?
3. Which panel and inverter brands do you recommend and why?
4. What performance guarantees and workmanship warranties are offered?
5. Can you provide monitoring data or case studies from past clients?
