Commercial Solar Rebates Australia: What Business Owners Need to Know
Why Commercial Solar Rebates Matter for Australian Businesses
Australia’s solar rebate framework is among the most robust globally. Businesses across the country are saving thousands each year through government-backed solar incentive programs. Whether you’re in manufacturing, agriculture, education, or retail — installing commercial solar can reduce your reliance on grid energy and shrink your power bill.
Key Solar Incentives Available in Australia for Businesses
✅ STCs: Small-scale Technology Certificates for Businesses
Perfect for systems under 100kW
- Instantly applied as an upfront discount via your installer.
- Based on system size and local solar performance.
- Covers solar panels and battery storage up to 50kWh.
- Typical savings: up to 30% off system cost.
✅ LGCs: Large-scale Generation Certificates Explained
For commercial systems over 100kW
- Rebates earned over time based on metered solar output.
- Must register under the Large-scale Renewable Energy Target (LRET).
- Requires quarterly certificate creation and trading.
- Value decreases annually until 2030.
✅ Battery Rebates for Businesses
- STCs now apply to commercial battery systems up to 50kWh.
- You can install up to 100kWh in one installation but still only claim for the first 50kWh
- You only get one claim – if you upgrade your battery later you cannot claim on the second phase of the install.
