Solar for Perth retirement villages and aged care facilities

Perth's retirement villages and residential aged care facilities (RACFs) are among the strongest commercial cases for solar in WA. High daytime occupancy, consistent electricity consumption, and large rooftop areas combine to make solar economics particularly favourable. For individual residents in these settings, understanding how solar works (and who benefits financially) is increasingly relevant as energy costs rise.

Why aged care facilities have strong solar economics

High daytime occupancy: Unlike residential households where most people are at work during solar generation hours, retirement villages and aged care facilities have high occupancy and activity throughout the day. Air conditioning runs at full capacity during summer; cooking, laundry, and common area operations continue all day. This aligns well with solar generation hours (8am–5pm in summer, 9am–4pm in winter).

Large rooftop areas: Aged care facilities and retirement village common buildings typically have substantial flat or low-pitch roofs — ideal for large commercial solar systems. A typical Perth aged care facility might have 1,000–3,000m² of usable roof area, enabling 100–300kW of solar generation.

Operating 365 days per year: Unlike office buildings that are largely empty on weekends, aged care facilities have consistent seven-day-a-week operation. Solar generation on weekends is self-consumed, not exported at low rates.

High electricity costs: Aged care facilities are significant electricity consumers — kitchen operations, air conditioning across multiple zones, laundry, medical equipment, and lighting accumulate rapidly. A facility spending $200,000–$600,000/year on electricity can dramatically reduce this cost with commercial solar.

How solar is installed in retirement villages

Retirement villages typically have two distinct electricity scenarios:

Independent living units (ILUs): Self-contained dwellings (villas, townhouses, apartments) within the village. Each has its own Synergy connection and electricity account. Solar installed on an ILU's roof benefits the resident of that specific ILU.

Serviced apartments and high-care facilities: Common-area solar (on the main building) benefits the operator's electricity bill, not individual resident accounts. Some village operators pass savings to residents through service charge adjustments; others retain the benefit.

Embedded network villages: Some newer Perth retirement villages operate as embedded networks — residents receive electricity from a shared system managed by the operator, potentially including on-site solar. See the embedded networks guide for details on resident rights in these arrangements.

For individual retirement village residents

If you're a resident in an independent living unit and want to install solar on your unit's roof:

Check your village's solar policy: Many Perth retirement village operators (Amana Living, Southern Cross Care, Bethanie, Uniting AgeWell, etc.) have solar installation policies that apply to resident units. These may specify:

• Approved installers (some operators maintain approved panels lists)
• Roof penetration and racking requirements
• Whether residents own the system or it reverts to the village
• Whether solar can be installed at all (some strata plans restrict modifications)

Check your residency agreement: The residency agreement (or occupancy agreement) governs modifications to the unit. Solar installation is typically considered a modification that requires operator approval.

Who owns the system at departure: In many village contracts, improvements made to the unit stay with the unit — meaning you don't take the solar system when you leave. Some villages allow residents to sell the system to the incoming resident or the village. Clarify this in writing before installing.

DEBS eligibility: If the unit has its own Synergy meter, DEBS applies to solar exports. If the unit is on an embedded network, DEBS credits go to the network operator, not the resident.

For families considering the energy cost impact

Electricity costs are embedded in retirement village service fees (the ongoing monthly or quarterly charge covering maintenance, facilities, and services). As operator electricity costs rise, service fees tend to follow. An operator with substantial solar on-site has lower operating costs, which may translate to lower fee increases over time.

When choosing a Perth retirement village, asking about on-site solar is a reasonable due diligence question — both as a signal of operator financial management and as an indicator of future service fee trajectory.

Government concessions in retirement village settings

Pensioner electricity concession (EAP): Perth pensioners and concession card holders in retirement village ILUs with a direct Synergy account are eligible for the EAP concession in the same way as any other Synergy residential customer. Solar does not affect EAP eligibility.

Residents in serviced accommodation (high-care): Residents whose electricity is bundled into aged care fees (rather than a separate Synergy account) typically access energy concessions differently — through the aged care fee framework or directly via Centrelink entitlements rather than Synergy bill credits. Clarify with the facility's administration which arrangements apply.

WA Battery Incentive: The $130/kWh battery incentive (up to $1,300) is available to eligible residential properties. An ILU with a direct Synergy account is eligible. Serviced apartments whose electricity comes through the facility's system would not typically be eligible at the individual resident level.

Village operators: the commercial solar case

For village operators, commercial solar ROI in Perth typically achieves 3–5 year payback on systems sized to cover common area and facility consumption. Key considerations:

• System size: 100–300kW systems on facility rooftops are typical; Western Power network applications are required above 10kW three-phase (8–16 weeks processing time)
• Grid connection: Most aged care facilities have three-phase supply; large systems may require a new Western Power network connection application
• Battery storage: Large-scale battery storage (100–500kWh) reduces peak demand and provides backup power for critical loads (emergency systems, medical equipment)
• Depreciation: Solar asset depreciation through standard capital allowance provisions reduces tax liability for for-profit operators
• ESG reporting: Solar installations contribute to sustainability reporting for aged care operators subject to reporting requirements

Perth retirement villages and aged care facilities have some of the strongest solar economics of any property type — high daytime occupancy, large roof areas, and year-round operation make self-consumption high and returns reliable. Individual residents in independent living units should check village policies and residency agreements before installing on their own units, and clarify ownership arrangements at departure. DEBS applies to direct Synergy accounts; embedded network residents receive credits via the operator.
