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.
The Northern Territory has the best solar resource in Australia and, unusually, a dedicated apartment solar rebate: grants covering up to half the installation cost of a shared system, to a cap per dwelling. Combined with a common load dominated by air conditioning that runs when the sun is at its strongest, the Territory has the strongest raw case for apartment solar in the country — provided the system is specified for the climate that produces it.

Territory support for shared solar PV systems on apartment complexes, covering a share of installation cost up to a cap per dwelling. Confirm the current round, cap and eligibility before you budget.

The national certificate scheme. The Territory sits in the highest-yield zone, so each kilowatt installed earns more certificates than the same system further south.

Air conditioning dominates, and it runs in daylight. The self-consumption figure is usually excellent.
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.
Wind rating, fixing specification and marine-grade hardware near the coast. This is the part that separates a system that lasts from one that does not.
A roof-mounted array in a cyclone region is a material change worth disclosing before installation.
So a cheaper, unrated quote cannot be substituted after the vote.
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.
Territory conditions shorten equipment life. Plan the replacement realistically.
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.
The cheapest quote in the Territory is frequently the one that is not rated for where it is going.
A significant roof modification in a cyclone region should not be a surprise at claim time.
Heat shortens inverter life. Plan on Territory numbers, not a national average.
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.
The physical job takes a few days. The decision takes most buildings a year. Quarter compresses the second one.
Your actual common power spend, from your actual bills, rather than a vendor's estimate of a building like yours.
Scope, cost, funding, and the effect on levies — put as a resolution rather than a proposal, with the quotes attached.
The resolution, the quotes, the scheme details and the consumption history, in one place, on the day the round opens.
Quotes, contracts, approvals, invoices and warranties recorded against the decision that authorised them.
The bill before and the bill after, visible to every owner, so the next project is an easier conversation than this one was.
