Commercial Solar Brisbane

Commercial solar costs in Brisbane vary depending on system size, roof condition, site access, electrical infrastructure, equipment and network requirements. As a guide, commercial solar systems typically cost around

$700–$1,200 per kW installed after applicable incentives, with larger systems generally achieving a lower cost per kW. Sharp EIT provides site-specific modelling so you can understand the expected project cost, available incentives, savings and payback before proceeding.

The right commercial solar system size depends on your electricity usage, operating hours, available roof or land area, tariffs and network constraints. Sharp EIT models when and how your business uses power to recommend a system size designed around onsite solar use, expected savings and future energy requirements.

Commercial solar projects in Brisbane and South East Queensland are generally within the Energex distribution network, while Ergon Energy Network covers much of regional Queensland. Network requirements can affect system design, export capacity, protection requirements and the grid connection process. Sharp EIT assesses the requirements that apply to the site and manages the relevant network application and approval process as part of project delivery.

Commercial solar installation timelines depend on system size, site complexity, network approvals and any required electrical or structural works. Smaller rooftop systems can generally be installed more quickly, while larger industrial, car park and ground-mount projects require longer engineering and delivery programs. Sharp EIT confirms the expected approval and installation timeline during the site assessment and plans works to minimise disruption to the business.

Yes. Commercial solar can be designed alongside battery storage, or an existing solar system can be assessed for battery integration. Battery storage may help increase onsite use of solar generation, manage peak demand, shift energy use into higher-cost periods or provide backup capability where required. Whether battery storage makes financial sense depends on the site's load profile, tariffs, solar generation and operating hours.

Sharp EIT delivers commercial solar across Greater Brisbane, including Brisbane CBD, North Brisbane, South Brisbane, East Brisbane and West Brisbane, as well as surrounding areas including Logan, Ipswich, Moreton Bay, Redlands, the Gold Coast and Sunshine Coast. Our commercial solar team also supports projects across regional Queensland, with each project assessed against the local electricity network and site requirements.

Yes. Eligible Brisbane businesses can access commercial solar finance options that can reduce the upfront capital required for a project. Sharp EIT can compare finance and outright purchase options as part of the project assessment. Finance is provided through DLL and is subject to approval.
