Quick answer: For the large majority of Sydney homeowners planning to stay put more than a few years, buying — cash or via a green loan — delivers substantially better long-term value than leasing, because rebates go directly to you and paid-off solar becomes essentially free electricity.
Updated August 2026 for NSW residents.
Solar leasing and power purchase agreements (PPAs) get pitched hard on "no upfront cost," but that convenience comes with real long-term trade-offs. For most homeowners planning to stay in their property, buying comes out ahead on nearly every measure that matters. Here's a straight comparison of how ownership models actually stack up in 2026.
Under a typical solar lease, a third-party company owns the system installed on your roof. You pay a fixed monthly lease fee, or in a PPA structure, pay per kWh generated (usually at a rate below your grid electricity price). You get the benefit of reduced power bills without an upfront payment, but you never own the equipment.
Key characteristics:
Buying means you own the system outright from day one, whether you pay cash or use finance (a green loan, for example — see our dedicated finance guide). You receive the STC discount and any battery rebates directly, reducing your upfront cost.

Key characteristics:
| Factor | Leasing / PPA | Buying (cash or finance) |
|---|---|---|
| Upfront cost | None or minimal | Rebate-inclusive price, paid upfront or financed |
| Who gets the rebates | Usually the leasing company | You, directly |
| Ongoing cost | Fixed monthly fee or per-kWh rate, long-term | None once paid off (financed term or immediate if cash) |
| Total cost over 20+ years | Typically higher | Typically lower |
| Asset ownership | No — company owns the system | Yes |
| Resale value impact | Neutral to negative (contract must transfer) | Generally positive |
| Maintenance responsibility | Usually the leasing company | You (or your installer under warranty) |
| Flexibility to upgrade | Limited — locked into contract | Full flexibility |
Leasing can make sense for a small number of specific situations: households with genuinely no access to upfront cash or finance approval, or those who strongly prioritise zero commitment of capital over long-term savings. It can also suit short-term-focused buyers who don't plan to stay in the property, though even here, transferring a lease at sale can complicate a settlement.
For the large majority of Sydney homeowners planning to stay in their property for more than a few years, buying — whether outright or via a green loan — delivers substantially better long-term value. Because rebates go directly to you as the owner, and because paid-off solar becomes essentially free electricity, the total cost of ownership over 15–20 years is typically well below the cumulative cost of an equivalent lease or PPA over the same period.
This is the detail leasing pitches often gloss over: the STC discount and, where applicable, the federal and NSW battery incentives are designed to reduce the cost for whoever owns the system. In most lease and PPA structures, that's the leasing company, not you. You're effectively financing someone else's rebate-discounted asset through your monthly payments, without capturing that discount yourself. Over the life of a 10–25 year lease, that's a meaningful amount of value you never see.

Owned solar systems, particularly well-specified ones with premium panels and a strong remaining warranty, are broadly viewed as a value-add by buyers and, increasingly, by valuers and agents in the Sydney market. A leased system, by contrast, can complicate a sale — the new owner typically needs to either take over the lease contract (subject to the leasing company's approval and credit checks) or you may need to buy out the remaining contract before settlement, which isn't always straightforward or cheap.
For most homeowners planning to stay put, buying — cash if you can, or via a straightforward green loan if you'd rather preserve savings — comes out ahead of leasing on nearly every measure that matters over the long run: total cost, rebate capture, ownership, and resale simplicity. Leasing has a narrow, legitimate use case for cash-constrained buyers, but it should be entered with a full understanding of what you're giving up, not just the appeal of no upfront cost.
For most Sydney homeowners staying more than a few years, buying is better. It wins on total cost, rebate capture, ownership, and resale simplicity over the long run. Leasing has a narrow, legitimate use case for buyers with no access to upfront cash or finance who prioritise zero capital commitment.
Usually the leasing company. The STC discount and any battery incentives are designed to reduce cost for whoever owns the system — under most lease and PPA structures that's the leasing company, not you. You effectively finance someone else's rebate-discounted asset through your monthly payments.
Generally yes, particularly well-specified systems with premium panels and a strong remaining warranty, which buyers, valuers and agents increasingly treat as a value-add. A leased system can instead complicate a sale, since the buyer must take over the contract or you may need to buy it out before settlement.
Yes. Buying doesn't require cash — a green loan lets you own the system from day one while spreading the cost, and you still receive the STC discount and any battery rebates directly. See our finance guide for how payment plans work.
