Solar on heritage homes: Burnside, Unley, Norwood, North Adelaide

Where heritage applies in Adelaide

Adelaide has more heritage-overlay homes per capita than any other Australian capital. The councils with the strongest character preservation policies are:

• City of Adelaide (State Heritage, North Adelaide character)
• City of Burnside (Toorak Gardens, Kensington, Beaumont, Glen Osmond)
• City of Unley (Hyde Park, Malvern, Unley Park)
• City of Norwood Payneham St Peters (Norwood, Kent Town, St Peters)
• Town of Walkerville (Gilberton, Vale Park, Walkerville)
• City of Prospect (Prospect, Fitzroy, Nailsworth)
• City of Mitcham (Mitcham, Hawthorn)

What 'heritage' actually restricts

Not panels on the actual roof, but panel visibility from the street. The standard council rule:

• Rear-roof installs (not visible from the street): typically OK without Development Approval.
• Side-roof installs: case-by-case.
• Street-facing front-roof installs on a heritage-listed home: usually requires Development Approval, sometimes refused.

What helps approval

• All-black panel frames (instead of silver or aluminium).
• Black backsheet (not the standard white).
• Flush-mounted (low-profile rails, not tilt frames).
• Recessed from the roof edge (typically 1-2 panel rows back).
• No street-visible MC4 connectors or DC cabling.

Panels that meet all of the above: REC Alpha Pure-R, SunPower Maxeon 7 black, Q.CELLS Q.PEAK DUO BLK ML-G10+, LG NeON H+ Black, Trina Vertex S+ all-black.

Process to follow

1. Confirm your home's heritage / character zone status with your council planning portal (Burnside Council, Unley Council etc all have public maps).
2. Speak with council planning informally before signing a contract. Most council planners are happy to give pre-lodgement advice for free.
3. If formal Development Approval is needed, your installer should handle it as part of the contract scope. Allow 4-12 weeks.
4. If approval is refused for front-roof, the rear-roof typically still works. North-east split or pure east-west may be more financially efficient anyway.

Stress test

Before signing, ask the installer:

• Have you done other heritage installs in [my suburb]?
• Will you submit Development Approval if my council requires it?
• Will you absorb the council fee or pass it through?
• What's your contingency if approval is refused for the front roof?

A quality heritage-experienced installer will have ready answers. A budget installer will say 'we just put them on the rear' and may not handle the approval process at all.
