Model monthly repayments for a battery system, and check whether the WA Government's interest-free Battery Loan covers your install.
The WA Government offers an interest-free loan up to $10,000 for eligible battery installations, with a household income cap of $210,000. The loan stacks with the $130/kWh upfront rebate (up to $1,300) for Synergy customers, capped at 10kWh of battery capacity.

Solar Batteries Perth does not broker or sell finance. If the WA Government loan doesn't cover your full install cost, or you aren't eligible, the common options Perth households use are:
The rebate ($130/kWh, capped at $1,300) is applied as a discount on the install, not as a separate payment to you.
Synergy customers on the SWIS network, with a household income at or below $210,000 per year, installing a CSIP-AUS compliant battery from the Synergy Supported Solutions List and joining a VPP. Full criteria are on the rebates page.
Yes. The $130/kWh upfront rebate (capped at $1,300 for Synergy customers, up to 10kWh) reduces the install cost, and the interest-free loan can fund up to $10,000 of what remains.
The gap is covered by your own cash or a separate loan. A typical 10kWh Perth install after the Synergy rebate sits in the $8,000–$15,000 range; the WA loan covers most or all of it depending on the system you choose.
Through the WA Government's administering body. The Solar Batteries Perth rebates page links to the official application and lists the documents you need.
