Commercial Solar Perth

Commercial solar costs in Perth 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.

Yes. For commercial solar projects connected to the Western Power network, the amount of solar that can be exported can depend on the site's connection, available network capacity and the outcome of Western Power's assessment. Larger systems may require a more detailed connection process and can be subject to export limits or additional technical requirements. Sharp EIT considers these requirements during system design and manages the relevant network application and approval process as part of project delivery.

Most commercial solar projects in Perth and the South West Interconnected System are connected through Western Power, while Horizon Power services many regional and remote areas of Western Australia. Connection, generation and export requirements vary depending on the network and site location. Sharp EIT assesses the requirements relevant to the site and incorporates them into the system design and connection process.

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 and reduce reliance on exporting excess solar to the grid. Whether battery storage makes financial sense depends on the site's load profile, tariffs, solar generation, operating hours and network requirements.

Sharp EIT delivers commercial solar across Greater Perth and regional Western Australia, supporting businesses, industrial facilities, farms, wineries and remote operations. Our coverage includes Perth’s major commercial and industrial areas, regional centres, wine and agricultural regions such as Margaret River and the Swan Valley, and mining and remote sites across regional WA. Each project is assessed against its location, energy requirements, site conditions and applicable electricity network.

Yes. Eligible Perth 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.
