Install solar on your building in Western Australia — Quarter

The roof is already there.

Australia and New Zealand put solar on more detached houses than almost anywhere on earth, and almost none on apartment buildings. Not because the roofs are wrong — because nobody owns the decision. A building's roof is common property, the power bill it would offset is a common cost, and the paperwork sits with a committee that has enough to do. That is a solvable problem, and in several states somebody will pay for half of it.

Install solar on your building in Western Australia

Western Australia has no apartment solar grant, but it has something most states do not: an excellent solar resource, and the Distributed Energy Buyback Scheme, which pays more for exported power in the afternoon peak than in the middle of the day. For a strata company that changes the design question — this is a market where orientation and, eventually, storage matter more than raw system size.

Governed by the Strata Titles Act 1985, administered by Landgate.

At a glance — WA

Main funding
No WA apartment-specific solar grant is currently open. Federal STCs apply.
Export
The Distributed Energy Buyback Scheme pays a higher rate for power exported in the afternoon peak than during the middle of the day.
Design implication
West-facing capacity and, later, storage are worth more in WA than an over-sized north-facing array.
Decision needed
A general meeting resolution — the roof is common property.
Quorum
Owners holding at least 50% of lots. Organise proxies before the meeting.

Programmes open, allocate and close, and the terms change between rounds. Check the current position with the administering body before you budget around any of these.

How to do it in Western Australia.

  1. 1

    Get the common power bills and the consumption profile

    Not just the total — when the building uses power. WA's buyback rates make the shape of the day matter.

    In Quarter: The building's common property spending is already in Quarter — this year's power bills and the two years before them — so the figure the whole business case rests on is one you pull rather than reconstruct from a drawer.

  2. 2

    Design against the tariff, not the roof area

    Afternoon generation is worth more than midday generation under the buyback scheme. That changes orientation and sizing.

    In Quarter: Recover the running cost through the same ledger as the levies, so charging is invoiced, collected and reconciled rather than tracked in somebody's spreadsheet.

  3. 3

    Check the roof's remaining life

    Do the roof first if it is close.

  4. 4

    Line up the quorum before the meeting

    Fifty per cent of lots is the highest threshold in the country and the usual reason a good motion fails in WA.

    In Quarter: Build the motion from the quotes and the budget, send the notice to every owner off the ownership register on the statutory clock, and record the vote as it is cast — a decision carries its majority automatically and emails the outcome to whoever raised it.

  5. 5

    Put a costed motion and authorise the council to contract

    So the project can proceed after the vote without a second meeting.

  6. 6

    Put the array in the ten-year maintenance plan

    Required for larger WA schemes anyway, and the inverter replacement belongs in it.

    In Quarter: Upload the plan you already have and Quarter reads it into a costed schedule of items, lifecycles and due years. From there it projects the fund thirty years out and tells you the annual contribution that actually funds it.

Where WA buildings get caught.

Sizing for maximum generation rather than maximum value

Under the buyback scheme these are not the same system.

Failing quorum

The most common WA failure, and nothing to do with whether owners support the project.

Leaving the array out of the maintenance plan

It is a common property asset with a service life.

Why solar pays differently in an apartment building

A house puts solar on to cut one household's bill. A building puts solar on to cut a bill every owner is already paying through their levies — lifts, lighting, pumps, ventilation, the car park. That common load runs during the day, which is exactly when the panels produce.

Common power is a daytime load
Lifts, corridor lighting, pumps and ventilation run while the sun is up. The match between generation and consumption is better in an apartment building than in most houses.
It reduces levies, not just a bill
Every dollar off the common power bill is a dollar that does not have to be raised from owners. That is the argument that carries a general meeting.
The roof is doing nothing else
In most buildings the roof is an asset with no use and a maintenance cost. Solar is the cheapest way to make it earn.
Grants exist here in a way they do not for most common property work
Almost nothing else a building has to do comes with public co-funding. Solar frequently does.

How Quarter gets the panels on

The physical job takes a few days. The decision takes most buildings a year. Quarter compresses the second one.

Build the case from your own numbers

Your actual common power spend, from your actual bills, rather than a vendor's estimate of a building like yours.

Get a motion owners will pass

Scope, cost, funding, and the effect on levies — put as a resolution rather than a proposal, with the quotes attached.

Hold the evidence a grant application needs

The resolution, the quotes, the scheme details and the consumption history, in one place, on the day the round opens.

Track the project through to commissioning

Quotes, contracts, approvals, invoices and warranties recorded against the decision that authorised them.

Show owners what it did

The bill before and the bill after, visible to every owner, so the next project is an easier conversation than this one was.

Questions we get asked.

Who gets the power — the building or the apartments?
Both models exist. The simplest is to offset common property load only: the system feeds the building's own supply, and the saving shows up as a lower common power bill. Sending power to individual apartments requires either an embedded network or a solar-sharing arrangement, which is a bigger project with more moving parts.
What if the roof needs work?
Then do the roof first. Installing panels over a roof with five years left in it means paying to remove and reinstall them. This is the most common sequencing mistake in the whole project.
Do we need everybody to agree?
No — you need the resolution the legislation requires, which is usually an ordinary majority at a general meeting where the strata company funds work on common property. Unanimity is not the test, and waiting for it is why buildings never start.
What about batteries?
Usually a second stage. Get the generation in first, see the real consumption pattern for a year, then size storage against it rather than against a guess.
