Going commercial solar shouldn't be this complicated.
Every business owner knows solar can save money. The hard part is knowing which system size actually pays back, what incentives apply, and which installer to trust with a six-figure asset.
Quotes you can't compare
Every installer quotes different kW sizes, panels and payback figures. We line them up side-by-side against your actual interval data.
Incentives nobody explains
STCs, LGCs, battery support, depreciation — we show which ones your business qualifies for and what they're worth in dollars.
Capital tied up elsewhere
You don't need to spend cash. $0-upfront finance and PPA structures let the savings pay for the system.
Cut Your Business Energy Costs With Commercial Solar
Businesses are the best fit for solar: you use power when the sun shines, so almost every kWh your roof produces replaces expensive grid power.
- Lower operating costs — lock in cheaper daytime energy for 25+ years
- Reduce peak demand charges — pair solar with a battery to shave peaks
- Tax & incentive benefits — upfront STC/LGC incentives plus depreciation*
- Meet ESG & tender requirements — measurable emissions cuts
*Estimates for businesses with strong daytime usage. Results vary by site.
How Much Could Commercial Solar Save Your Business?
Move the slider to your average monthly power bill. We’ll estimate the right system size, yearly savings and payback period.
Indicative estimate only, based on typical commercial energy rates (~28c/kWh, excluding fixed & demand charges), average state solar yields and installed pricing after STC incentives. Your real result depends on tariff, roof, usage profile and final system design.

Commercial solar questions, answered
Can’t see your question? Call our team on 0485 854 270.
How much does commercial solar cost?
Pricing depends on system size, roof type, switchboard upgrades and location. As a guide, commercial systems are typically priced at around $900–$1,300 per kW installed after STC incentives. Your free assessment gives you an exact figure.
What incentives are available for businesses?
Systems up to 100 kW can claim upfront Small-scale Technology Certificates (STCs). Larger systems can generate Large-scale Generation Certificates (LGCs) over time. Eligible batteries may also attract support. Businesses may be able to depreciate the system — we outline what applies to you and your accountant can confirm the tax treatment.
We lease our building — can we still get solar?
Often, yes. Many landlords approve solar because it adds value to the property, and PPA or finance structures can be set up to suit your lease term. We can help prepare the proposal for your landlord.
How long does installation take? Will it disrupt operations?
Most small-to-medium commercial systems are installed in a few days, with a short planned shutdown for connection. Systems over 30 kW need network approval, which adds a few weeks beforehand. Installers work around your trading hours.
Should we add a battery?
If you pay high demand charges, operate in the evening, or export lots of solar, a battery can improve returns. Your assessment models solar-only and solar + battery so you can compare.
