Solar Panel Cleaning for Rental Properties: Landlord and Tenant Responsibilities

Solar panels on rental properties sit in a legally murky area that many landlords and tenants navigate badly — sometimes ending in warranty-voided panels, bond disputes, or years of degraded system performance that nobody acted on.

This guide clarifies the responsibilities in each Australian state, explains what should be in a tenancy agreement, and gives both landlords and tenants practical guidance for keeping solar panels clean and functional throughout the tenancy.

The Legal Framework

Solar panels are a fixture attached to the property — like a ducted air conditioning system or built-in oven. Under Australian residential tenancy law in all states and territories, the landlord is responsible for ensuring the property (including fixed fixtures) is in a reasonable state of repair and maintenance.

Key principle: If solar panels are part of the property at the start of the tenancy, maintaining them in working order is generally the landlord’s responsibility unless the tenancy agreement specifically and clearly assigns maintenance tasks to the tenant.

State-by-State Overview

State/Territory	Solar Panel Maintenance Responsibility	Key Notes
NSW	Landlord (unless lease assigns to tenant)	Residential Tenancies Act 2010 requires landlord to maintain premises in reasonable repair
VIC	Landlord	Residential Tenancies Act 1997, as amended — landlord responsible for appliances and fixtures
QLD	Landlord	RTRA 2008 — landlord responsible for “reasonable state of repair”
WA	Landlord	Residential Tenancies Act 1987 — fixtures maintained by landlord
SA	Landlord	Landlord responsible for maintaining all fixtures in working order
TAS	Landlord	Residential Tenancy Act 1997
ACT	Landlord	Residential Tenancies Act 1997
NT	Landlord	Residential Tenancies Act 1999

What This Means in Practice

For Landlords

If you own a rental property with solar panels, you are responsible for:

1. Annual professional cleaning — as part of routine property maintenance
2. Inverter servicing — addressing error codes and faults promptly
3. Bird proofing — if bird damage or nesting is causing deterioration
4. Post-storm inspection — checking for panel damage after severe weather
5. Addressing output decline — if tenants report the system isn’t working as expected

Neglecting solar panel maintenance isn’t just bad for the asset — it can be used by tenants as grounds to escalate to the relevant tenancy tribunal if they’re not receiving the electricity benefit they were promised as part of the rental arrangement.

Best practice for landlords: Schedule an annual professional solar panel clean as part of routine property maintenance (alongside gutter cleaning, pest inspection, etc.). Budget $180–$280 for a standard 6.6 kW system.

For Tenants

If you’re renting a property with solar panels:

1. You benefit from the solar electricity generated — either through lower bills or a sub-metered arrangement negotiated with the landlord
2. You are responsible for reporting issues — if you notice significantly reduced output, a dashboard alarm, or visible panel damage, notify your property manager in writing
3. You are generally NOT responsible for cleaning — unless your tenancy agreement specifically and clearly states otherwise
4. Do NOT attempt DIY cleaning — if you use incorrect methods and damage the panels, you may be liable for repair costs. Always request cleaning through your property manager

When Can a Landlord Ask Tenants to Clean?

A landlord can assign solar cleaning responsibility to a tenant IF:

1. The tenancy agreement explicitly states this obligation (not just a generic “maintain appliances” clause)
2. The panels are safely accessible (single-storey, low pitch, reachable without professional equipment)
3. The tenant is not expected to perform tasks that require professional skills or equipment
4. The assigned task doesn’t create WHS risk to the tenant

Even if a tenancy agreement assigns cleaning to the tenant, the landlord remains responsible for any damage caused by roof inaccessibility, panel fault, or circumstances outside the tenant’s control.

What Should Be in a Tenancy Agreement

For landlords drafting or reviewing lease agreements:

Recommended clause (with legal review before use):

“The landlord is responsible for the annual professional cleaning and maintenance of the solar photovoltaic system, including panels and inverter. The tenant agrees to notify the property manager promptly of any visible damage to panels, error codes on the inverter display, or significant unexplained reduction in system output.”

Avoid vague language like “tenant to maintain all appliances” — this is unlikely to be enforceable for solar and creates confusion.

If you intend for the tenant to perform cleaning, use specific language:

“The tenant is responsible for cleaning solar panels [X times per year] using appropriate soft-brush and purified water techniques. The landlord will provide cleaning equipment at the start of the tenancy. The tenant must not use pressure washers, abrasive cleaning products, or chemical cleaners on panels. Any damage caused by non-approved cleaning methods may be claimed against the tenant’s bond.”

Common Disputes and How to Avoid Them

”The solar panels aren’t working and my electricity bills are the same”

This is the most common tenant complaint. Often caused by accumulated soiling, inverter fault, or the tenant never being shown how to monitor the system.

Prevention: At tenancy commencement, the landlord or property manager should:

• Show the tenant how to access the inverter monitoring app
• Explain what normal output looks like seasonally
• Provide a contact for reporting issues

Resolution: Landlord arranges professional clean and/or inverter check within a reasonable timeframe (typically 14–21 days for non-urgent maintenance).

”The tenant tried to clean the panels and scratched them / voided the warranty”

Prevention: Clearly state in the tenancy agreement that tenants must not attempt DIY solar cleaning, and that all maintenance requests should go through the property manager.

Resolution: If damage is proven to be tenant-caused and caused by action outside the scope of their tenancy agreement, the landlord can claim repair costs from the bond — but must be able to prove causation.

”The landlord hasn’t cleaned the panels in three years and output has dropped significantly”

Tenants may have grounds for complaint if a landlord’s failure to maintain panels has materially reduced the solar benefit that was an explicit or implied feature of the tenancy.

Prevention: Annual professional cleaning as standard property maintenance.

Managing Solar in a Strata or Apartment Building

Where solar panels are on common property (shared roof), maintenance is the responsibility of the owners corporation / body corporate, not individual lot owners or tenants. If you rent a unit and the building has rooftop solar:

• Energy may be distributed to common areas and units via a sub-metering arrangement
• The owners corporation is responsible for panel maintenance
• Raise maintenance concerns with the building manager or strata committee

Practical Landlord Checklist

✅ Schedule annual professional solar panel clean as part of property maintenance calendar
✅ Ensure tenancy agreement has a clear, specific clause on solar responsibilities
✅ Provide tenants with inverter monitoring app access and basic usage guidance at start of tenancy
✅ Respond to tenant maintenance reports within the legally required timeframe for your state
✅ Conduct a solar system health check before re-letting (between tenancies is the ideal cleaning opportunity)
✅ Consider bird proofing if bird activity has been noted — protects long-term asset value

Conclusion

Solar panels on rental properties add value to landlords and real savings to tenants — but only when properly maintained. In Australia, maintenance is the landlord’s default responsibility, and annual professional cleaning is a reasonable and legally prudent standard.

Both parties benefit from clear lease language, good communication, and a landlord who treats solar maintenance as the routine asset management it is.
