Commercial Solar Batteries in Australia: Costs, Benefits, and ROI

Author : Nichols Robbins | Published On : 29 Oct 2026

SAA-accredited installation is required for federally supported small-scale batteries and NSW BESS4 projects. BESS5 sits on a different pathway, with its own licensed-installation, planning, network and fire-safety requirements. Victoria has no dedicated state grant for a typical mid-scale business battery.
Payback varies with tariff structure, demand profile, incentives, and upfront cost. We provide a project model so you can see expected savings and operational value before you proceed. At present, there is no equivalent broad commercial solar incentive across every Australian state and territory. Businesses may have a compelling use case, queensland solar and battery grant but upfront capital remains a barrier. Previously, some businesses had an incentive to design around the 100 kW STC threshold.

Incentives are generally delivered as an upfront discount through an Accredited Certificate Provider. Some incentives are available nationally, while others are only offered in certain states or territories. Indicative federal STC discount for a common 6.6kW system; the exact amount varies by postcode zone and install timing.
We can develop a renewable energy roadmap for your business to help you get there. Tailored EV charging solutions for businesses including fleets, destinations and workplaces. Our in-house installation teams schedule works around your business operations, with staged installations where needed to minimise disruption. Sharp EIT Solutions partnered with The Greater Western Sydney GIANTS to deliver a 139kW commercial rooftop solar system across key areas of the club’s high-performance facility.
BESS4 provides incentives for eligible small to medium commercial battery installations. Without battery storage, excess solar energy is often exported to the grid for a relatively low feed-in tariff. During daylight hours, rooftop solar panels generate electricity for the business. Modern commercial battery systems combine several technologies that work together to safely store, manage, and supply electricity when required. Solar is a 25-year decision, so the panels, inverter and installation quality matter far more than shaving a few hundred dollars off the quote. RS Energy is a family-run solar company and we design every Archerfield system around your roof, your shading and your bills.

Transform underutilized assets like rooftops, surplus ground areas, or parking lots into sources of energy generation. Sunpark Solar enables you to monetize excess renewable energy by participating in grid programs like net metering. Connects homeowners with trusted, vetted solar installers across Australia.
Future-proof your business with tailored solar and battery solutions, Australia-wide. There are many funding options available for businesses looking to reduce their impact. Take a look at our range of financing options, as well as environmental certificates and government funding to help pay for your next renewable energy project. This depends on system size, panel and inverter brand, and installation difficulty. For an in-depth breakdown on the cost of solar panels, read our full guide.
A commercial solar battery is a large-scale energy storage solution that pairs with your solar PV system to store surplus electricity generated during the day. That energy can then be used during peak demand hours, grid outages, or high-tariff periods. Solis Energy is unique amongst renewable energy retailers and installers. We are one of the few companies in Australia selling and installing solar systems, battery storage systems, and EV Chargers. Our combined technical knowledge enables us to offer this unique specialised service.

A solar battery installation in Archerfield enables you to use your stored power at night or during peak demand periods when grid electricity is most expensive. This reduces reliance on the grid, increases energy independence, and ensures a reliable power supply during outages. Most commercial battery systems installed today use lithium iron phosphate (LFP) battery technology because it offers excellent safety, long service life, and high efficiency.
If a site is being upgraded more broadly, it is worth planning the pieces together. A battery may interact with commercial solar, commercial EV charging, commercial LED lighting and commercial heating and cooling. Coordinating electrical capacity, controls and capital works early can avoid redesigning one upgrade around another later. From the outset Australian energy upgrades have been of great assistance even after the installation they were still there. Prices were competitive and Derek helped when little obstacles from the power supply put in a charge I wasn’t expecting. My friend also engaged A E U and was pleased with the entire process and service.
The exact quote can move depending on panel and inverter choice, roof access, switchboard work, monitoring, warranty level, and whether battery readiness is included. Based on 2935 local reviews across installers listed for Archerfield. Sales were very good at explaining and quoting the system, as well as the installation team delivery the fantastic installation."
