Commercial electricity costs are a major overhead for Queensland businesses. A well-designed commercial solar system can eliminate 50–80% of your business's electricity bill — and with accelerated depreciation options available, the after-tax payback period can be under 3 years.
Why Commercial Solar Makes Business Sense
Immediate Bill Reduction
Solar generation during business hours directly offsets your highest-cost tariff consumption — peak daytime demand charges included.
Tax & Depreciation Benefits
Commercial solar qualifies for instant asset write-off and accelerated depreciation under the ATO's energy efficiency provisions. Consult your accountant for details.
LGC Income
Systems above 100kW generate Large-scale Generation Certificates (LGCs) that can be sold for additional income — on top of energy bill savings.
ESG & Brand Value
Customers and partners increasingly prefer businesses with credible sustainability credentials. Rooftop solar is the most visible sustainability commitment a business can make.
Commercial System Sizes We Install
We handle commercial installations from small-business scale through to large industrial arrays:
| Scale | System Size | Typical Application |
|---|---|---|
| Small Business | 10–30kW | Retail, office, small warehouse |
| Medium Commercial | 30–100kW | Medium warehouse, shopping centre tenant |
| Industrial / Large | 100kW+ | Industrial, large commercial, agribusiness |
Our Commercial Installation Approach
- Energy audit and load analysis: We review your electricity bills, tariff structure, and operational load profile to design a system that maximises ROI.
- Roof and structural assessment: Commercial roofs vary widely. We assess load-bearing capacity, membrane type, and access requirements before designing the mounting system.
- System design and ROI modelling: You receive a detailed ROI model including payback period, 10-year and 25-year cash flow projections, and sensitivity analysis.
- Approvals and grid connection: We manage all Energex applications, DNSP approvals, and retailer notifications.
- Staged installation (if required): Large commercial installations are often staged to minimise business disruption. We plan around your operating hours.
- Monitoring and reporting: Commercial systems include professional energy monitoring with monthly performance reports.
STCs vs LGCs for Commercial Systems
- Systems under 100kW are eligible for the Small-scale Renewable Energy Scheme (STCs) — the discount is applied at point of sale, just like residential solar.
- Systems 100kW and above create Large-scale Generation Certificates (LGCs) instead. LGCs are created based on actual generation and sold in the renewable energy certificate market for ongoing income.
