What is a heritage overlay?
A heritage overlay is a planning control that protects places with historical, architectural, or cultural significance. If your property is within a heritage overlay, any external changes, including installing solar panels, may require council approval.
Heritage protections can apply at different levels: state heritage listings protect the most significant places and have stricter requirements, while local heritage overlays or heritage conservation areas managed by your council are more common and often more flexible about solar installations.
How to check if your home is affected
- Search your council's online planning maps for heritage overlays
- Check your state's heritage register (e.g. NSW Heritage, Heritage Victoria)
- Review your property certificate for heritage notations
State-by-state heritage rules
NSW
Heritage items listed under Local Environmental Plans (LEPs) typically require a Development Application (DA) for solar panel installation. Exempt development provisions under the State Environmental Planning Policy generally do not apply to heritage-listed properties.
Approval authority: NSW Heritage Council / Local Council
VIC
Properties with a Heritage Overlay (HO) in the planning scheme usually need a planning permit for solar panels. Some councils allow panels on non-street-facing roof areas without a permit, but check your specific overlay schedule.
Approval authority: Heritage Victoria / Local Council
QLD
Heritage-listed places under the Queensland Heritage Act require approval from the Department of Environment and Science. Local heritage places listed in council planning schemes need council approval.
Approval authority: Qld Heritage Council / Local Council
SA
State Heritage Places require approval from the SA Heritage Council. Local heritage and contributory items in Historic Conservation Zones need council Development Approval. Panels hidden from street view may have a simpler approval pathway.
Approval authority: SA Heritage Council / Local Council

Compliant installation options
Rear-of-Roof Placement
Installing panels on the rear or non-street-facing side of the roof is the most common approach for heritage homes. Many councils will approve panels that are not visible from the public domain.
Flat or Low-Profile Panels
Low-profile mounting systems keep panels flush against the roof, reducing visual impact. Some all-black panels sit as low as 30mm above the roof surface.
Colour-Matched Frames & Panels
All-black panels with black frames and black mounting hardware blend with dark roof materials. For terracotta or slate roofs, the reduced visual contrast can help satisfy heritage requirements.
Ground-Mount Systems
If roof-mounted panels are not permitted, ground-mount arrays in the rear yard are an alternative. They avoid any roofline alteration and can be positioned for optimal sun exposure.
Council approval process
Check Your Heritage Status
Search your local council planning maps or state heritage register to confirm whether your property is heritage listed, in a heritage conservation area, or subject to a heritage overlay.
- Search your council's online planning portal
- Check the state heritage register
- Look for Heritage Overlay (HO) or Heritage Conservation Area (HCA) on your property certificate
Pre-DA Consultation with Council
Before lodging a formal application, contact your council's heritage planner for a pre-application meeting. They can advise on what will likely be approved and save you time and fees.
- Request a pre-DA meeting with the heritage planner
- Bring photos of your roof and proposed panel locations
- Ask about any local policies for solar on heritage properties
Prepare and Submit Plans
Lodge your Development Application (DA) or planning permit application with detailed plans showing panel placement, mounting method, and visual impact from the street.
- Include a site plan showing panel locations on the roof
- Provide a photomontage or visual simulation if requested
- Document how the installation is reversible and non-damaging
Coordinate with Your Installer
Share the council approval conditions with your installer before work begins. A heritage-experienced installer will know how to meet these requirements during installation.
- Choose an installer with heritage property experience
- Ensure the approved panel model and layout are followed exactly
- Keep approval documents on-site during installation

Frequently asked questions
Can I install solar panels on a heritage-listed home?
Yes, in most cases you can install solar on a heritage home. You will typically need council or heritage authority approval, and panels may need to be placed on non-street-facing roof areas or use low-profile mounting systems.
How do I know if my home has a heritage overlay?
Check your local council planning maps or search the state heritage register. Your property certificate (Section 149 in NSW or Section 32 in VIC) will also show any heritage overlays or listings.
How long does heritage approval for solar panels take?
Timeframes vary by council. A straightforward application for panels on a non-visible roof area may take 4 to 8 weeks. More complex applications involving street-facing panels or state-listed properties can take 3 to 6 months.
Do heritage solar installations cost more?
There may be additional costs for council application fees (typically $200 to $600), heritage-specific panel options like all-black modules, and low-profile mounting systems. The solar system itself is priced similarly to a standard installation.
What happens if I install solar without heritage approval?
Installing without approval can result in council enforcement action, fines, and a requirement to remove the panels at your own cost. It may also create issues when selling the property. Always obtain approval before installation.
