## Key Facts

- Based in Sydney, Australia
- Operated by Amperage
- Covers all Australian states and territories (NSW, VIC, QLD, SA, WA, TAS, ACT, NT)
- Uses real TMY weather data for solar production estimates
- Calculates STCs (Small-scale Technology Certificates), LGCs (Large-scale Generation Certificates), and VEECs (Victorian Energy Efficiency Certificates)
- Announced 5 August 2026: STC eligibility is set to expand from 100 kW to 1 MW for solar installed from 1 October 2026, subject to regulations being made. The regulations were not registered at the time of writing, so the 100 kW limit is still the law today; the Amperage public calculators price the announced 100 kW to 1 MW band and flag those figures as pending regulation.
