Rooftop commercial solar — sized, quoted and installed end to end
What Is Commercial Solar?
Commercial solar is a rooftop or ground-mount solar PV system sized to offset a business's daytime electricity demand rather than a single household's. Because commercial tariffs often include demand charges on top of usage rates, a correctly sized system can reduce both the energy you buy and the peak demand you're billed for — while Small-scale Technology Certificates (STCs) reduce your up-front cost.
Ausgreen Solar Solutions designs commercial systems around your actual load profile, connection point and roof or land constraints, then manages installation end to end — from site inspection through to system handover and after-sales monitoring support.
☀️ STC Value Reduces Over Time — Lock In Sooner Rather Than Later
The number of Small-scale Technology Certificates (STCs) a system can claim is based on a deeming period that steps down each calendar year until the scheme phases out in 2030. That means the upfront rebate available for the same system size is generally higher the earlier you install. Speak with our team to confirm current STC eligibility for your project.

What A Well-Run Commercial Solar Project Looks Like
Commercial solar is a 25-year decision. These are the things worth getting right from the start.
- Confirm your installer is CEC-accredited and check their track record independently
- Size the system to your actual daytime load profile, not just available roof space
- Understand your demand charges and how solar and battery storage each affect them
- Get an itemised quote that clearly separates hardware, installation, STCs and any rebate
- Ask about the performance and workmanship warranty terms in writing
- Set up monitoring from day one so underperformance is caught early
- Plan for cleaning and maintenance rather than treating the system as "install and forget"
- Choosing an installer on price alone without checking CEC accreditation or reviews
- Oversizing or undersizing the system relative to actual business energy use
- Ignoring demand charges when only usage-rate savings are quoted
- Ticking off installation without agreeing to monitoring or after-sales support
- Leaving STC and rebate eligibility unconfirmed until after the contract is signed
- Skipping ongoing cleaning and maintenance, letting output quietly degrade
Government Incentives That Can Reduce Your Upfront Cost
Depending on your location and eligibility, several government schemes can be combined with your commercial solar project.
Commercial Solar By Business Size
Every quote is tailored to your site and energy profile — this is a general guide to how businesses typically approach system size. See our Commercial Solar Installation Cost page for current cost guidance.
Small Business
Offices & Retail Typically single-tenancy sitesSized to offset daytime office or shopfront usage, often paired with a battery for after-hours load.
Medium Business
Warehousing & Light Industry Larger roof footprint, higher daytime loadLarger rooftop arrays targeting both usage-rate savings and demand-charge reduction.
Large Business
Manufacturing & Multi-Site Complex load profilesLarger systems, sometimes multi-site, designed around detailed interval usage data and demand management.

Frequently Asked Questions
How is commercial solar different from a residential system?
Commercial systems are sized around a business's daytime load profile and often need to account for demand charges, three-phase power, and larger or more complex roof layouts than a typical home. See our Residential Solar System page if you're comparing the two.
What is an STC and how does the rebate work?
A Small-scale Technology Certificate (STC) is created for eligible solar installations and can be sold on a certificate market for a dollar rebate, reducing your upfront system cost. The number of certificates a system can claim reduces as the scheme's deeming period steps down each year toward 2030.
Do you assess my roof without a site visit?
In most cases, yes — we use satellite and mapping tools to assess roof space, and this is accurate in the large majority of cases. Where it isn't, we send an agent to inspect on site at no extra charge.
What warranty comes with a commercial solar system?
We only use top-listed panel, inverter and battery brands, most of which carry a 25-year performance warranty. Our installations are also backed by a 10-year workmanship warranty.
Can I monitor my system's performance?
Almost all inverters include an online monitoring system accessible from a smartphone, tablet or PC. We can also add SkyBox Energy Management for more detailed visibility into generation and consumption.
What government schemes might apply to my business?
Depending on your location, this can include STCs, the NSW Home Energy Saver zero-interest loan, the Cheaper Home Batteries Program, the NSW Peak Demand Reduction Scheme, or ACT and Tasmanian Government household and business schemes. See our Government Incentives (STC) page for more detail.
