WA no-interest loan

Zero interest.
Still a real loan.

The government-backed pathway is administered by Plenti and remains subject to eligibility, verification, credit assessment and responsible lending.

It can cover the battery plus eligible new or upgraded inverter and solar equipment installed with the battery. The loan and WA rebate together cannot exceed the eligible purchase and installation cost.
