Commercial Solar Battery Rebates

In Western Australia, businesses can take advantage of solar incentives to lower upfront costs and boost sustainability. The federal Small-scale Renewable Energy Scheme (SRES) provides Small-scale Technology Certificates (STCs) that reduce costs based on system size and installation date. Starting in July 2025, the Cheaper Home Batteries Program will also offer generous rebates for battery systems.

Westsun Energy makes the process simple by applying discounts at the point of sale and managing all the paperwork, so your business gets the maximum savings without the stress. Learn more about WA solar rebates.
