Commercial Solar Systems
Cut the Cost of Running Your Business.
Commercial solar systems designed for your site, your load and your long-term financials - installed by accredited specialists who understand what's at stake.
Energy Is Your Business's Most Controllable Cost
Commercial energy bills aren't fixed. Every poorly timed peak, every unmanaged demand charge, every kilowatt you buy at retail rates when the sun is free - these are costs you can control.
Off The Grid designs and installs commercial solar systems for Australian businesses that are serious about their energy strategy, not just their next quarterly bill. You get a system built for your site, sized for your loads and supported for the long term.
The Cost of Doing Nothing Just Keeps Rising
Commercial electricity prices in Australia have climbed steadily for over a decade, and the trajectory isn't changing. Businesses that keep absorbing those increases are funding energy retailers - not their own growth.
The real risk isn't just the rising baseline rate; it's demand charges, peak tariff exposure and creeping operational vulnerability.
But when your site generates its own power, your peak exposure shrinks, and your energy costs become something you plan around rather than react to.
Commercial Solar Built Around Your Operation
Here's how we help Australian businesses take control of their energy costs, protect their operations and build resilience into their sites:
Slash Your Electricity Bill on a Large Commercial Roof
If your site has significant roof space, you have the raw material for meaningful, sustained bill reduction - but only if the system is sized correctly for how your business actually uses power:
- Detailed load profiling to match system output to your real consumption patterns, not generic estimates
- High-output panels engineered for Australian commercial conditions - Canadian Solar TOPHiKu6 (up to 670W, 23.3% efficiency, 30-year performance warranty) and JA Solar Deep Blue 4.0 (600W+, 1500V DC compatible) proven in 550kW+ Australian deployments
- Bifacial N-type TOPCon cell technology squeezing maximum generation from every square metre of available roof
- Structural ratings to 5400 Pa accommodating cyclonic conditions and commercial roof types across Australia
- Payback modelling integrated into your proposal so the financial case is clear before you commit
A correctly sized commercial solar array doesn't just offset your bills - it becomes a predictable, long-lived energy asset with a return you can put in a spreadsheet.
Keep Operations Running Through Outages
Grid reliability is deteriorating in parts of Australia, and the financial consequences of unplanned downtime vary from inconvenient to catastrophic depending on your business. The right backup strategy changes your vulnerability profile entirely:
- UPS-class switchover in milliseconds - GoodWe Lynx and AlphaESS Storion both deliver instant backup with no perceptible interruption to critical loads
- Priority load protection ensuring servers, refrigeration, production lines and safety systems stay live while non-critical loads are managed
- SigenStor's 0 ms transfer time and smart load ports allow precise control over which circuits are backed up and in what order
- Backup capacity scalable to meet your specific critical load requirements - not a one-size solution that leaves gaps
- Remote monitoring with instant alerts so your team and ours both know if the system is called upon
Your operations keep running. Your data is protected. Your customers don't notice. The grid becomes a backup, not a single point of failure.
Eliminate Demand Charges and Peak Tariff Exposure
For most commercial energy users, the demand charge line on your bill is the one that hurts most - and solar alone doesn't fix it. Pairing solar with the right battery storage changes that equation entirely:
- AI-driven charge and discharge scheduling timed to your tariff structure, automatically shifting load away from expensive peak periods
- SigenStor commercial configurations (up to 30 kW / 48 kWh per tower, three-phase) with mySigen demand management and EV charging integration
GoodWe Lynx C / BAT-C (19.2-112 kWh range, paired with 15-110 kW ET Plus/Pro inverters) with SEMS cloud monitoring and VPP-ready architecture - AlphaESS Storion series (30-100 kW per system, modular from tens to thousands of kWh) for larger industrial and warehouse loads
- SAJ Electric CHS2 pre-assembled cabinets (51-180+ kWh, 10-50 kW three-phase inverter integration, 95% round-trip efficiency, CEC-approved for rebates)
When the system is working in concert, demand charges shrink, peak tariff exposure drops, and your energy bill starts to reflect a site that's actively managing its own power.
Solar for Multi-Site or Growing Businesses
If you're managing energy costs across more than one location - or planning expansion - the architecture of your system matters as much as the equipment in it. Modular, scalable design is not an upgrade option; it should be built in from day one:
- System design that anticipates growth, with inverter capacity, electrical infrastructure and monitoring platforms that accommodate future expansion without costly retrofits
- Risen Energy RSM144-9 panels (560-585W, N-type TOPCon bifacial, 87.4% output at year 30) delivering bankable long-term performance across every site
- AE Solar ME-120BS (530-600W, German-engineered, IP68, cyclonic-rated frames) providing the build quality and warranty backing required for multi-site rollouts
- Centralised monitoring across all locations so energy managers can track performance, flag underperformers and report on consumption from a single platform
- Staged deployment strategies that let you build out the business case site by site, with each installation informing the next
A multi-site solar rollout done well compounds over time - each site performing, each data point sharpening the next decision, the whole portfolio building toward genuine energy independence.
Only the best brands.
A Commercial Solar Company You Can Count On
We Speak Commercial, Not Just Solar
Most solar installers start with panels and work backwards. We start with your load profile, your tariff structure and your payback requirements. Commercial energy is more complex than residential - demand charges, three-phase loads, compliance requirements and capital justification all change the equation. Our teams understand this from the ground up, which means you get recommendations based on your operation, not a residential playbook applied at scale.
Australian-Owned, Locally Accountable
We're not a franchise or an overseas operation managing Australian projects remotely. Off The Grid is Australian-owned with local teams who understand local conditions, local grid requirements and local compliance standards. When something needs attention, you're speaking directly to the people responsible for your system.
Quality Equipment, Transparent Financial Case
We work with Tier-1 manufacturers whose commercial panels carry 30-year performance warranties and whose products are deployed in megawatt-scale Australian projects. Every proposal includes clear payback modelling so the financial case is documented and defensible - not a sales pitch.
Systems Built for the Long Term
Commercial solar is a 25-30 year asset. We design with that horizon in mind - future battery integration, inverter capacity that accommodates load growth, monitoring infrastructure that keeps delivering value as your operation evolves. The right decisions made at design stage cost nothing extra and save significantly over the life of the system.

Your Questions Answered
How do I know what size system my business actually needs?
System sizing for commercial sites is based on your real load profile - how much power you use, when you use it and what your peak demand looks like. A generic kW figure without that analysis is guesswork. We model your actual consumption against roof capacity and tariff structure before recommending a size, so the system is built to deliver a return, not just to fill a roof.
Does solar work for my type of business?
If your site has daytime electricity consumption and adequate roof space, solar almost certainly makes financial sense. We work across manufacturing, retail, warehousing, hospitality, healthcare and professional services. The specifics vary, but the core calculation - offset expensive daytime grid consumption with on-site generation - applies broadly.
Can battery storage really reduce my demand charges?
Yes - this is one of the strongest financial cases for commercial battery storage in Australia. Demand charges are calculated on your peak consumption in a billing period, often just a 15-30 minute window. A battery configured to limit those peaks can significantly reduce that line item, often delivering payback independently of the solar system's contribution.
What does the installation process involve for a commercial site?
We manage the full process: structural and electrical assessment, design, equipment procurement, installation, compliance certification, grid connection and commissioning. For operating businesses, we plan installation to minimise disruption - typically working in stages and scheduling critical switchover work outside business hours where needed.
