Send one bill. Get the real numbers on commercial solar.
Most solar quotes start with a guess about how much power you use. Ours starts with your electricity bill, so the system you're shown is sized against what your site actually draws and the payback figure means something.
Reply within 48 hours. We read every bill ourselves.
What you get back
- 01A system size in kilowatts, worked out from your consumption profile rather than your roof area.
- 02Installed cost, the STC discount applied to it, and what you'd actually pay.
- 03Annual saving and payback, with the assumptions listed so you can argue with them.
- 04Anything that could stop the project: switchboard capacity, roof condition, export limits on your part of the network.
How it runs, start to finish
01
You send a bill
One recent bill, every page. Two minutes on the form. If you've got interval data from your retailer, even better, but it isn't required.
02
We read it properly
Consumption by time of day, demand charges, tariff structure, seasonal swing. This is where most of the value sits and where most quotes skip straight past.
03
A system gets designed
Sized to your load, checked against your roof on satellite imagery and against your network's export rules, then priced with current equipment costs.
04
You get a written proposal
Numbers, assumptions and risks in one document. Take it, question it, or use it to sanity-check a quote you already have. No follow-up campaign either way.
Indicative ranges
What a commercial system costs
Three sizes that cover most of what we see. Published so you can work out whether this is worth a conversation before you send anything.
| System | Roof area | Installed | After STCs | Saved a year | Payback |
|---|---|---|---|---|---|
| 30 kW~54 panels | 150–190 m² | $28,000 – $38,000 | $21,000 – $29,000 | $7,000 – $11,000 | 2.8 – 4.1 years |
| 50 kW~90 panels | 250–320 m² | $44,000 – $58,000 | $33,000 – $44,000 | $12,000 – $18,000 | 2.6 – 3.8 years |
| 100 kW~180 panels | 500–620 m² | $82,000 – $110,000 | $62,000 – $84,000 | $24,000 – $36,000 | 2.5 – 3.6 years |
Ranges, not quotes. Roof type, switchboard condition, network approval and how much of your load falls in daylight hours move every one of these numbers. The proposal you get back replaces this table with figures for your site.
Where we quote
Rebates, network rules and how much a panel generates all change by state. Each of these pages covers what applies where your site is.
How we're paid, and what you actually get
Commercial Solar Quotes reads your electricity bill, sizes a system against your actual consumption profile, and returns a costed proposal prepared by an accredited commercial solar installer we work with.
We don't run an auction and we don't publish a panel of competing quotes. You get one proposal, built for your site, with the assumptions shown so you can check them or take them to another installer.
The installer funds this service so that it's free to use. They pay us to run it, not per project and not out of your quote, so nothing about what we recommend changes what we're paid. You pay nothing for the assessment, and there's no obligation to accept the proposal.
Questions we get asked
What does the assessment cost?
Nothing. You send a bill, we size a system against your consumption and return a costed proposal. The installer who prepares it funds this service, so you're never invoiced for the work and we're not paid more if you say yes.
How many quotes do I get?
One, built properly, with the assumptions written down so you can check them or take them to another installer. We don't run an auction. Three rushed quotes based on the same guessed load profile are worth less than one built from your actual bill.
Why do you need the whole bill and not just the amount?
The amount owing tells us almost nothing. The consumption detail on the later pages tells us how much you use, when you use it, what your demand charges look like and what tariff you're on. That's what a system gets sized against.
We lease the building. Is solar still worth looking at?
Often yes, and it depends on the lease term and the landlord. If you've got five or more years left there's usually a structure that works, whether that's the landlord funding it against a rent adjustment or you funding it with a make-good agreement. Tell us the situation and we'll say honestly whether it stacks up.
How long until we hear back?
Within 48 hours for a first response. A full proposal takes a few days longer because it involves a look at your roof, your network's export rules and the actual equipment pricing that week.
Send us a bill and we'll do the sums
One recent bill is enough to size a system and price it. It costs nothing, there's no obligation, and you'll hear back within 48 hours.
