Install solar on your building in New Zealand — Quarter

The roof is already there. New Zealand.

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 New Zealand

New Zealand's grid is already about 80 to 90 per cent renewable, so solar here is bought for the bill rather than for the emissions — and with electricity prices where they are, the bill argument is strong enough on its own. There has been no long-standing residential solar subsidy, though EECA has signalled that Warmer Kiwi Homes is expanding to include solar, with eligibility still being worked through. In the meantime, low-interest lender finance is how most body corporates fund it.

Governed by the Unit Titles Act 2010, administered by Unit Titles Services.

At a glance — NZ

Main funding
No established body corporate solar grant. EECA has signalled that Warmer Kiwi Homes is expanding to include solar, with details still to be confirmed.
How buildings fund it
Low or zero-interest energy loans from New Zealand retail banks are the usual route.
Why it still stacks up
Retail electricity prices and a daytime-weighted common load — lifts, pumps, lighting, ventilation.
Decision needed
A body corporate resolution — the roof is common property.
Then
Record the array in the long-term maintenance plan, which is compulsory under the Unit Titles Act 2010.

Bank energy-efficiency lending

Several New Zealand lenders offer low or zero interest finance for solar, batteries and other energy upgrades. Where no grant applies, this is the practical funding route for a body corporate.

How to do it in New Zealand.

  1. 1

    Pull twelve months of common power bills

    New Zealand seasonal variation is significant. A full year is the only useful basis.

    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

    Check whether you are a large development

    Ten or more principal units changes your maintenance planning and disclosure obligations, and a capital project this size belongs in the plan.

    In Quarter: Ask Quarter and it quotes the Unit Titles Act and Regulations directly — the notice period, the quorum, the threshold, in the Act's own words rather than a paraphrase of them.

  3. 3

    Check the roof before anything goes on it

    The long-term maintenance plan should already tell you when the roof is due. Use it.

  4. 4

    Line up the finance

    Confirm what your lender offers and whether the body corporate can borrow in its own right.

  5. 5

    Put a costed motion to a general meeting

    Consumption, quotes, saving, funding route. Minute it and distribute the minutes within the required period.

    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.

  6. 6

    Update the long-term maintenance plan

    Compulsory in New Zealand, and a new common property asset with a service life belongs in it from installation.

    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 NZ buildings get caught.

Solar over a roof that is due

The plan usually already says when. Check it before you mount anything.

Leaving the array out of the plan

The plan is a statutory document, and an unlisted asset is a visible gap at the next review.

Sizing on summer output

New Zealand winter generation is much lower. Annual figures only.

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 body corporate 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.
