Shared Solar for Melbourne Apartments: Roof Rights, Metering and Bills

Shared solar for an apartment building starts with roof rights, electrical connections and an agreed way to share costs and benefits. Panel capacity comes after those questions, not before them.

A common-area system and a system supplying individual apartments can produce very different outcomes. Establish which electricity bills the project is intended to reduce before asking for a design.

Our solar team can help scope the technical assessment alongside the owners corporation's own decision process.

Confirm who controls the roof and the decision

Read the plan of subdivision and identify common property, lot boundaries and relevant building rules. A resident's access to the roof does not establish the right to install equipment there.

Consumer Affairs Victoria says owners corporation rules must not unreasonably prohibit sustainability items on a lot's exterior. That is not unrestricted permission to use common property without the required approval.

Consumer Affairs Victoria's rules guidance.

Have the owners corporation manager or appropriate adviser identify the required resolution, notices and voting process for this project. Record the decision and approved scope clearly.

Do not assume a casual majority at an informal discussion can approve every expenditure or alteration. The decision process and any incentive programme conditions both need attention.

Map the meters and the intended benefit

Identify the common-area meter, individual apartment meters and any embedded-network arrangement. Then map the loads the proposed solar would actually supply.

Solar connected only to common-area loads may reduce that account's imports without directly reducing each apartment's electricity bill. Explain how any shared financial benefit would be handled through the owners corporation.

A supported sharing system can allocate solar to participating apartment connections. The configuration must suit the building and the agreed allocation, rather than assuming every roof installation automatically shares energy.

Allume's SolShare guidance describes dynamic allocation and agreed sharing approaches. Its product description does not replace electrical assessment or building approval.

Our export-limit guide explains why the distributor connection still matters, including where several meters or inverters are involved.

Agree on costs and responsibilities before voting

Set out the upfront contributions, proposed allocation, maintenance budget and responsibility for support. Explain how new residents, sales, renters and later participants are handled under the agreed arrangement.

Clarify who owns the equipment, holds the monitoring account and can authorise repairs. Confirm access arrangements so a fault can be investigated without an improvised dispute over roof or switchroom entry.

Imagine a building with little common-area daytime demand but residents home during the day. A common-area-only proposal may leave substantial surplus, while a supported apartment-sharing proposal serves a different purpose.

The sharing option can also add equipment and management considerations. Compare both complete proposals rather than assuming the more complex design is automatically better value.

Our home electrification overview can help identify future loads, but common-property capacity should not be promised to individual projects without assessment.

Check current programme requirements separately

Solar Victoria's Solar for Apartments programme has specific eligibility and application requirements. These changed in September 2026, so old summaries should not be used to establish a building's entitlement.

Read the current Solar for Apartments guidance before setting a budget or installation date. Confirm eligibility, approval timing and the chosen retailer's responsibilities directly.

A rebate does not resolve roof defects, unsuitable electrical infrastructure or disagreements about allocation. Address those issues in the feasibility work rather than allowing an incentive deadline to define an incomplete project.

Prepare a brief containing the roof plan, meter arrangement, common-area usage, participating lots, decision authority and desired outcomes. Add the maintenance and access plan to the proposal owners will review.

Request an apartment solar assessment using that brief. A clear and fairly explained project is easier to evaluate than a panel quote with unresolved building responsibilities.
