1. What is the STC Calculation?

The STC (Small-scale Technology Certificate) calculation determines the number of certificates a heat pump installation is eligible for under Australia's Renewable Energy Target. These certificates can be sold to help offset the cost of the system.

2. How Does the Calculator Work?

The calculator uses the STC formula:

Where:

• \( Zone\ Factor \) — Determined by your location (climate zone)
• \( Deeming\ Period \) — Number of years the system is deemed to operate (typically 10 years for heat pumps)

Explanation: The equation accounts for the expected renewable energy production based on location and system lifespan.

3. Importance of STC Calculation

Details: Accurate STC calculation is crucial for determining the financial benefit of installing a heat pump system under Australia's renewable energy scheme.

4. Using the Calculator

Tips: Select your zone factor based on your location and enter the deeming period (typically 10 years for heat pumps). All values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: What are the different zones in Australia?
A: Australia is divided into 4 zones based on climate conditions, with Zone 1 being the most favorable for renewable energy generation.

Q2: What is the typical deeming period for heat pumps?
A: The standard deeming period for heat pumps is 10 years under the Small-scale Renewable Energy Scheme.

Q3: How do I determine my zone factor?
A: Your zone factor is determined by your postcode. Check the Clean Energy Regulator's zone map for exact details.

Q4: Can I claim STCs for an existing system?
A: No, STCs can only be claimed for new eligible systems installed by accredited installers.

Q5: How are STCs valued?
A: STC prices fluctuate based on market demand. The value is typically between $30-$40 per certificate.
