Starting points for Northcote homeowners
Darebin's 'Step by step' story documents the electrification of a particular older Northcote residence, including rooftop solar and later battery installation. Results depend on that house's design and use and must not be applied to every Northcote property.
This guide is an introduction to the questions that might apply locally, not a statement that every property in Northcote has the same roof or electricity requirements.

Recorded solar activity in postcode 3070
As at 31 August 2026, Clean Energy Regulator records show 2,784 solar installation events and 14.7 MW of recorded rated solar capacity in postcode 3070.

The CER counts certificate-backed installation events, including new systems, upgrades and stand-alone systems. It is not a count of unique homes. Postcode 3070 may also cover places beyond Northcote, so these figures are postcode-level context rather than a statistic about every Northcote 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.
Understand the building before finalising rooftop equipment
A renovation can change roof penetrations, heating loads and electrical layouts. If a house is subject to actual heritage or shared-property requirements, ask the relevant authority before choosing equipment placement. A council case study about an older property isn't evidence that your own roof has similar constraints, so commissioning a site-specific design remains essential.
Questions worth asking
- What roof and switchboard conditions were checked at this address?
- Could planned insulation or heating changes alter demand?
- Are any current planning or ownership approvals needed for this particular installation?
Evaluate winter as well as summer storage scenarios
The Darebin Northcote case study explicitly distinguishes performance across the year. For your household, a battery proposal should show usable capacity, backup reserve and the likelihood of replenishing stored energy in winter. Comparing only an ideal summer day can lead to a misleading assessment of additional storage capacity.
Questions worth asking
- How much daily surplus is modelled in winter rather than summer?
- How much of the battery's usable capacity might remain unused across the year?
- What circuits, if any, have actually been designed for outage backup?
Compare a staged purchase with buying everything at once
Installing solar first can provide real generation and import/export data for a later battery assessment, while installing together may reduce some duplicated work. Compare both options against actual quotes and current, verified federal discount rules. Do not assume an older case study's rebate amounts or product configuration remain available.
Questions worth asking
- What additional work would a later battery installation require?
- Which current incentives apply to the proposed equipment and installation date?
- Would measured post-solar data meaningfully improve the sizing decision?
