Apartments & Strata

Energy for shared spaces.

Solar and storage for common-property services.

Common-area systems do not automatically supply individual apartments.

Apartment concept with recessed balconies and low-tilt rooftop solar

Decide which meter—and whose loads.

A strata project needs an agreed energy recipient and a workable approval pathway. Common-property generation and supplying individual apartments are distinct project scopes.

Are we supplying common property?

Common lighting, lifts, ventilation and shared facilities are a useful starting point. Confirm the common meter and consumption profile before sizing PV or storage. Do not assume that a shared roof means all dwellings receive electricity.

Who needs to be involved?

Bring the strata manager or owners corporation into the discussion with the electrical and building contacts. Roof rights, access, approval requirements and maintenance responsibilities need project-specific confirmation.

What information moves the project forward?

Common-area bills or interval data, roof plans, meter and switchboard information, plus the committee’s objective. A battery discussion also needs an equipment-location and access assessment.

Technical details.

System integration

Connect to the common loads.

An indicative common-property system connects rooftop PV to the common switchboard, which supplies lifts, lighting and building services. Optional storage is separately designed. This does not imply supply to individual apartments.

System connections

From generation to building use.

Illustrative building energy connectionsAn illustrative electrical topology: PV array supplies an inverter through a DC route. The inverter supplies AC to the switchboard. Building loads and the grid connect separately to that switchboard. Optional AC-coupled storage has a separate battery inverter connection.

Design notes

Storage is shown as a separate AC-coupled branch. Metering, protection and isolation are omitted. Backup requires a separately designed arrangement. This is not a construction drawing.

Design considerations

A shared system needs a shared plan.

Apartment energy projects involve common-property rights, decision-making, metering and electrical infrastructure. Establishing those foundations helps the project team assess a realistic pathway.

Common-area demand

Lifts, common lighting, ventilation and shared facilities create the building load profile.

Metering & distribution

Common meters, switchboards and available capacity determine what can be connected and who receives the energy.

Approval & access

Owners corporation decisions, roof access, delivery logistics and ongoing responsibility need early agreement.

FAQs & enquiry checklist
Does common-area solar supply every apartment?

Not necessarily. A common-area system usually serves the common-property meter. Supplying individual apartments requires a separate assessment of metering, distribution and the proposed arrangement.
