Commercial Solar

Solar generation matched to the load your business actually runs in daylight, not a panel count sold off the roof. We model the payback against your tariff and demand, design for your three-phase supply and export limits, and stage the install around your trading so the site keeps running.

Scope

What this job includes.

  • Generation sized to your metered daytime load and demand profile
  • Three-phase design, switchboard works and network export approval
  • Warehouse, retail, agribusiness and strata roofs across the region
  • EV fleet and destination charging with load management (OCPP)
  • Staged works and live-site cutovers, scheduled around your trading
Our system: A commercial system pays back on the daytime load it offsets, so we model that first and size to it. The payback assumptions, the export limit and any switchboard upgrade are on the proposal as lines, and one accountable installer owns the job from design to commissioning.
How we quote it

The same itemised quote, every time.

Whatever the job, your quote names the panel and inverter, sizes the system to your bill and shows the STC as a figure, so you can see exactly what you are paying for.

The scope and compliance sheet
  1. 1 Sized to your bill. The array is sized to your metered usage and load profile, not to the biggest rebate on offer.
  2. 2 Panel, named. The exact SunPower (or specified) panel on the quote, with its product and performance warranty, not "premium panels".
  3. 3 Inverter, named. The exact Fronius (or specified) inverter and its warranty, sized to the array, not the cheapest unit on the van.
  4. 4 Shading + roof study. Orientation, pitch and shade assessed on site, with optimisers or microinverters specified where the roof needs them.
  5. 5 STCs shown as a dollar line. The federal STC incentive applied as a point-of-sale figure: gross price, STC value, net. Never a vague "rebate applied".
  6. 6 Warranties, itemised. Panel product, panel performance, inverter and workmanship listed separately with their years, so you can compare like for like.
  7. 7 Compliance + paperwork. Installed by our own crew to AS/NZS 5033 and 4777, with the Certificate of Electrical Safety and Certificate of Compliance named as deliverables.
If a quote does not show these lines, you cannot compare it, and you do not know what has been cut.
How it runs

What happens, step by step.

1

Site + usage assessment

We read your bills and load profile, study the roof orientation, pitch and shading, and check the switchboard and supply.

2

Design + named quote

You get the system sized to your usage, the panel and inverter named with their warranties, and the STC shown as a dollar line. The workings are on the page.

3

Approval + grid paperwork

Fixed scope, STCs handled, and the grid-connection and metering application lodged with your network and retailer.

4

In-house install

Our own crew installs to AS/NZS 5033 and 4777, never subcontracted. Staged around your trading hours for commercial sites.

5

Test + commission

Every string tested, the inverter commissioned and monitored, and the Certificate of Electrical Safety and Compliance issued.

6

Handover + monitoring

Monitoring set up on your phone, the warranties and certificates in your hand, and a walk-through of how the system runs.

Accredited, covered, warranted

The paperwork behind the price.

SAA SAA-PLACEHOLDER, EC-PLACEHOLDER, Public liability insured, and a Workmanship warranty workmanship warranty. All in writing, all on the quote.

A walk through exactly what is covered: the SAA accreditation and licence you can verify, the cover that protects your home, and the warranty that names its own exclusions instead of hiding them.

Questions, answered

Common Commercial Solar questions.

How is commercial solar sized differently to a home system? +
It is sized to the load you run in daylight, not your total bill. We pull your interval data, map your demand against the sun, and size the array to maximise self-consumption, because exported power earns far less than power you use on site. The model is on the proposal so you can see the assumptions.
What is the payback on a commercial system? +
For a business with a solid daytime load it is often three to six years, but it depends on your tariff, your demand charges and how much you self-consume. We model it on your actual interval data and show the numbers, including the STC value, before you commit.
Can you handle the network export approval? +
Yes. Larger systems need approval from the network for how much they can export, and sometimes an export limit or a dynamic controller. We handle the application and design to the conditions, so the system is compliant and you are not surprised by a knock-back after install.
Do you work around our trading hours? +
Yes. We stage commercial works and cut over live sections out of hours or in isolated steps so the site keeps operating. The method statement and isolation plan are agreed with your site manager before we touch a live board.
Can you add EV fleet charging? +
Yes, and it often pairs well with commercial solar. We design load-managed (OCPP) charging that draws from your generation where it can, with billing and access control for staff or fleet, and we size it to what the supply and switchboard can actually carry.
Do you offer a maintenance agreement for commercial systems? +
Yes. Commercial arrays earn their payback only if they keep performing, so we offer scheduled cleaning, monitoring and health checks that catch a dead string or a soiled array before it costs you a quarter of generation. The inclusions are scoped to your site.
Will solar cut our peak-demand charges, not just our usage? +
It can, but only if the system is designed for it. Many commercial bills are driven as much by peak-demand charges as by total usage, so we look at your interval data and, where it stacks up, pair solar with a battery or load management to shave the peaks. We model the demand-charge saving separately so you can see what the solar does versus what the battery does.
Buy outright, finance, or a PPA, which is right for us? +
It depends on your cash position and how you account for the asset. Buying outright gives the fastest payback and full ownership; finance spreads the cost while you save from day one; a power purchase agreement means little or no upfront cost and you buy the generated power at an agreed rate. We lay out the numbers for each against your usage so the choice is financial, not a sales push.
Do you run an energy audit before designing a commercial system? +
Yes, for anything beyond a small system. We pull your interval data and map your load against the sun before sizing the array, because a commercial system is sized to the load you run in daylight, not your total bill. That audit is what stops you over-buying export you will never use or under-sizing and leaving savings on the roof.
