Commercial Solar Sydney

Commercial solar costs in Sydney 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 see the expected project cost, available incentives, savings and payback before proceeding.

The right commercial solar system size for a Sydney business depends on your interval data, operating hours, available roof or land area, electricity tariffs and network constraints. Sharp EIT models when and how your business uses power, then recommends a system size designed to maximise onsite solar use, expected savings and financial return rather than relying on a simple bill-to-kW formula.

Commercial solar installation timelines in Sydney 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 your site assessment, with works planned to minimise disruption to your business.

Yes. Sydney businesses can often install commercial solar on leased premises with the landlord’s approval. The agreement should clearly address system ownership, access, maintenance and what happens at the end of the lease. Sharp EIT can assess the site and provide the technical and financial information you may need to discuss the project with your landlord. Read more: solar for renters vs owners.

Commercial solar projects across Sydney and NSW may connect through different electricity distribution networks depending on the site location. These include Ausgrid, Endeavour Energy and Essential Energy. Network requirements can affect system design, export capacity, protection requirements and the grid connection process. Sharp EIT assesses the requirements that apply to your site and manages the relevant network application and approval process as part of project delivery.

Sharp EIT installs commercial solar across Greater Sydney, including Western Sydney, the North Shore, Inner West, South Sydney, Hills District and Sutherland Shire, as well as across NSW including Newcastle, Wollongong, the Central Coast, Hunter Valley, Central Tablelands/Bathurst, Northern Rivers and regional NSW. Our team is based in North Ryde, Sydney.

Yes. Commercial solar can be designed alongside battery storage or an existing solar system can be assessed for battery integration. For Sydney businesses, a battery 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 your load profile, tariffs, solar generation and operating hours.
