Can You Install Solar on a Leased Warehouse in Sydney?

Yes, installing commercial solar on a leased warehouse may be possible, but the arrangement needs to work for both the tenant and property owner. Roof access and permission, equipment ownership, the lease term and who pays the electricity bill should be addressed before the solar system is designed or purchased.

The business that uses electricity may not own the building. This creates a common split incentive: the tenant could benefit from lower electricity bills while the landlord controls the rooftop and may be expected to fund improvements.

The Australian Government’s guidance for rental and multi-occupancy properties identifies this as a key consideration for solar on leased premises.

There are workable options, but they must be agreed for the individual property.

Why this matters in practice: Two identical Sydney warehouse roofs can have very different solar business cases. A tenant with a five-year lease, daytime energy demand and its own electricity meter has different incentives from a landlord with multiple tenants on separate accounts. The agreement must match the site’s actual metering and occupancy.

Possible commercial arrangements include:

• Landlord-funded solar: The building owner pays for and owns the system, with the parties agreeing how its value is reflected in lease terms.
• Tenant-funded solar: The business pays for the system with the landlord’s permission and agrees what happens when the lease ends.
• Shared or financed arrangement: Costs and benefits may be allocated through a negotiated agreement, lease variation or suitable finance structure.

None of these automatically offers the best return. A landlord who holds the property for many years may assess the system differently from a tenant with only a short period left on the lease.

Usually, the commercial electricity account and metering arrangement are crucial. If a tenant buys grid electricity and consumes on-site solar, it may receive much of the direct bill benefit. That does not by itself establish who owns the panels or who receives export credits.

Review the account holder, meter, operating hours and proposed ownership arrangement before calculating payback. MPV Solar’s Commercial Solar Payback Period guide explains how daytime consumption affects the return.

Also check whether the building has one National Metering Identifier (NMI) or multiple separately billed tenancies. A solar system is not automatically shared fairly across occupants just because it sits on a common roof.

Before installation, the parties should obtain appropriate contractual advice and agree on matters such as:

Roof permission and structure: Who can approve attachments, engineering investigations, access and future roof works?

Ownership: Who legally owns the panels and inverter during the lease and afterwards?

Maintenance: Who arranges and pays for servicing, repairs and insurance?

End of tenancy: Will the system stay, transfer or be removed? Who makes good the roof?

Energy and incentives: Which party receives energy savings, export credits and eligible incentives?

Possibly, but the remaining term matters. A system with a payback horizon longer than the secured tenancy needs careful modelling, especially if removal costs or uncertainty over equipment ownership could reduce the value.

Instead of relying on a generic return percentage, compare system cost, consumption, expected generation, tariffs, ownership rights and likely occupancy.

A useful first comparison is projected tenant electricity savings during the secured lease term against the tenant’s proposed contribution, maintenance obligations and end-of-lease costs. The answer may favour landlord ownership, negotiated cost-sharing or deferring the project, not necessarily a tenant-funded installation.

Yes. A suitable roof can still have constraints involving age, condition, skylights, asbestos, structural capacity, existing equipment or access. MPV Solar assesses these alongside the electrical supply and network connection requirements.
