> Commercial solar and battery quoting software for Australian solar professionals and energy consultants, plus free solar calculators for businesses.

Amperage is quoting software for Australian solar professionals and energy consultants who quote commercial solar and batteries. It takes a customer's electricity bill and consumption data, models solar production from local weather data and battery dispatch hour by hour, applies Australian incentives (STCs, battery STCs, LGCs, VEECs, PDRS), and produces sizing decks and branded proposals in about 10 minutes per bill. Businesses can use the free calculators and Solar Insight estimate without signing up.

## 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)
- STCs cover up to 1 MW of site capacity for solar installed from 1 October 2026, at a fixed 5-year deeming period for any install year through 2030 (Renewable Energy (Electricity) Amendment (Mid-scale Solar) Regulations 2026, registered 17 September 2026 and in force). Installs before 1 October 2026 earn STCs on the first 100 kW and LGCs on the balance. Eligibility tests the site's TOTAL capacity including related systems and accredited power stations; above 1 MW, the first 1 MW earns STCs and the balance earns LGCs. Amperage prices this band on its public calculators and by default in the workspace, switchable per project. Details: https://amperage.app/blog/stc-expansion-1mw-commercial-solar
- Free calculators and the Solar Insight quick estimate for businesses: no signup, a first result in about 30 seconds
- Solar professionals get a free Pro trial at signup; quoting from a bill to a credible estimate takes about 10 minutes
