Use this calculator to estimate the number of small-scale technology certificates (STCs) your solar battery installation may be eligible for based on the current STC factor and the future adjustments.
Disclaimer
The calculator:
- determines STCs based on proposed changes from 1 May that are still subject to Regulations (use the REC Registry - Small generation unit STC calculator for existing STC factors)
- is a guide only and does not consider all the variables which may affect the calculation of STCs
- is based on data that may be updated, so results can vary over time.
