Richmond is Melbourne's most architecturally dense inner suburb — a grid of Victorian terrace rows, worker's cottages, and converted industrial buildings where roof access and orientation are constrained by the sheer compactness of the built fabric. Yarra City Council's heritage overlay covers most of Richmond's residential grid, particularly the streets north of Bridge Road and the Punt Road corridor. Many individual properties are on the Victorian Heritage Register, requiring approval from Heritage Victoria (not just council) for any external works — including solar panels.
The terrace typology that defines Richmond creates a specific solar challenge: most terraces have a street-facing north slope (the front) and a lane-facing south slope (the rear). To be heritage-compliant, panels must go on the rear slope, which faces south. A south-facing system in Melbourne (37.8°S) generates roughly 55–65% of a north-facing equivalent. This isn't necessarily a dealbreaker — at Melbourne's electricity rates and with the VIC Solar Homes rebate, even a south-facing 6.6kW system can pay back in 5–6 years. But it changes the economics and you should model it explicitly rather than assuming standard payback figures apply.
The alternative for Richmond terrace owners is to look at the rear lane. Many Richmond properties have vehicle access from a rear laneway — Cubitt Lane, Highett Street lane, the various Hoddle grid service laneways. If your rear lane includes a garage or outbuilding roof with a north-facing slope, that may be your best solar option. Small outbuilding systems (2–4kW) on a north-facing garage roof often outperform a larger south-facing main-roof system. Get your installer to assess both options and model the output difference before deciding.

Homeowners in Richmond (3121) are in STC Zone 3, which provides approximately $2,400 off a 6.6kW system through the federal Small-scale Technology Certificate scheme. Your installer handles the STC paperwork — the rebate is applied automatically as a point-of-sale discount.
Victorian homeowners in Richmond may also qualify for the Solar Homes Program rebate of up to $1,400 on panels and $8,800 on batteries.
VIC solar rebates and government incentives — full guide →Richmond terrace owners should typically size to 3–5kW on available south-facing rear roof area. Larger systems on south-facing slopes are rarely justified — output doesn't scale proportionally with system size when the aspect is poor. The exception is properties with north-facing upper extensions, loft conversions, or garage roofs facing north — these can support 5–6.6kW and generate significantly better returns.

Frequently Asked Questions — Richmond
In theory, a front north-facing roof is the best solar aspect. In practice, most Richmond terraces with north-facing street frontages are heritage-listed, and Yarra Council and Heritage Victoria require panels to be non-visible from the street. This rules out the front slope. Some properties have first-floor additions or rear extensions with north-facing roofs not visible from the street — these are worth investigating. For many Richmond terraces, the honest answer is that solar works, but not optimally.
Yes, but model it explicitly. A south-facing 6.6kW system in Melbourne generates approximately 6,500–7,500 kWh/year compared to 9,500–10,500 kWh/year north-facing. At 27c/kWh and a 6.6kW system costing $5,500 minus $1,400 VIC rebate ($4,100 net), a south-facing system still pays back in approximately 5–6 years. The return is real, just slower. The VIC Solar Homes rebate significantly improves the economics of what would otherwise be a marginal installation.
Properties on the Victorian Heritage Register require a permit from Heritage Victoria for external works, including solar panel installation. This is a more formal process than local council heritage approval. The permit application requires photos of the proposed installation, a heritage impact statement (prepared by a heritage consultant), and demonstration that the installation will not impact the heritage significance of the place. It typically takes 2–3 months and costs $500–$1,500 in consultant fees. Contact Heritage Victoria early in your process.
