Using Debt Recycling When You Install Solar: What Actually Works

You can use debt recycling when you install solar on your home, but only if you keep the solar borrowing non‑deductible, create clean investment loan splits and maintain strong buffers. The ATO cares about purpose of each loan split, not what secures it, so the recycling piece must be clearly tied to income‑producing investments, not the panels themselves.

Quick answer:

1. Borrow (or use equity) for solar in a dedicated, non‑deductible home loan split.
2. Direct extra cashflow and solar savings into that split to pay it down faster.
3. Reborrow the repaid principal in a separate split only for investments (e.g. ETFs, investment property costs).
4. Keep perfect records and don’t mix personal spending or solar costs into the investment split.

Keep home, solar and investment borrowing in clean, separate loan splits to protect tax outcomes.

How solar actually fits into a debt recycling plan

Think of solar as a home improvement first, not an investment asset.

ATO rules treat most owner‑occupied solar as private use. Interest on borrowing for that purpose is not deductible, even if the loan is secured by your home or an investment property.

So where does debt recycling come in?

You use the cashflow improvement from solar (lower power bills) to speed up repayments on your non‑deductible home loan, then reborrow that freed‑up equity in a separate split purely for investments. The solar simply helps create the surplus.

Simple worked example

• Solar + battery cost: $25,000 (after rebates).
• You create a new home loan split: $25,000, 6.5% p.a., 20‑year P&I.
• Repayments ≈ $186/month.
• Solar reduces your power bills by, say, $120/month (after you haircut the installer’s glossy numbers by 20%).

If you top up repayments by an extra $120/month using the savings, you’re effectively repaying $306/month. That clears the solar split far faster, which then lets you reborrow that repaid principal in a separate investment split as part of a recycling plan.
