Starting points for Oakleigh homeowners
The Victorian Government identifies Oakleigh within Monash, whose Electrify My Home resources describe staged household upgrades including rooftop solar, batteries, efficient heating, induction cooking and heat-pump hot water. Current program availability should be checked directly before choosing a supplier.
This guide is an introduction to the questions that might apply locally, not a statement that every property in Oakleigh has the same roof or electricity requirements.

Recorded solar activity in postcode 3166
As at 31 August 2026, Clean Energy Regulator records show 2,070 solar installation events and 14.2 MW of recorded rated solar capacity in postcode 3166.
- Recorded installations
- 2,070 installation events
- Recorded capacity
- 14.2 MW
- Average recorded capacity
- 6.8 kW per installation event
- Older recorded cohort
- 32.0% from 2015 or earlier
- 2026 recorded installations
- 158 (provisional)
The CER counts certificate-backed installation events, including new systems, upgrades and stand-alone systems. It is not a count of unique homes. Postcode 3166 may also cover places beyond Oakleigh, so these figures are postcode-level context rather than a statistic about every Oakleigh property. The older-cohort share describes when events were recorded; it does not prove that the original equipment is still on a roof or needs replacement.
Sequence solar with the upgrades you really intend to make
A home replacing gas appliances gradually should distinguish its current electricity demand from a future all-electric estimate. Monash encourages residents to make an individualised electrification plan rather than assuming every upgrade must happen at once. Compare a solar-only proposal with a scenario that includes planned electric appliances, and make the timing assumptions explicit.
Questions worth asking
- Which appliances are definitely being changed, and when?
- Does each quote show current and future electricity-use assumptions separately?
- Would moving appropriate loads into daylight hours alter useful solar self-consumption?
Use the household's actual tariff and weekday routine
A projected saving calculated from an average household may not match a home where everyone is away by day or one with large daytime cooling demand. Use your bills or, where available, interval data to compare how much output might be consumed directly, exported or stored. Be wary of a sales proposal that applies one generic tariff or export credit to every Oakleigh property.
Questions worth asking
- Which import tariff and feed-in credit did the forecast use?
- How does our real daytime usage compare with the assumed load profile?
- What changes if our work or heating habits change?
Keep battery economics separate from the solar-panel decision
A battery can move eligible solar energy into evening usage, but capacity, output power, losses and net installed cost affect its value. Review Monash's guidance alongside independent federal incentive information; don't assume that a battery is essential for every solar installation. Compare the battery's incremental contribution rather than treating a combined quote as one undifferentiated purchase.
Questions worth asking
- What is the battery's usable capacity and power rating?
- What daytime surplus could realistically charge it in winter?
- Can each retailer itemise the battery price, federal discount and extra hardware?
