Green Deal New Calculator User Manual
We are excited to announce that Green Deal has launched its new consolidated calculator. This tool combines the calculation formulas for STC, BESS2, and BESS3/4/5 all in one place.
Follow the steps below to experience this new calculator.
Select the battery you are installing by using the drop-down lists to choose the battery's Brand and Model.
You can type in keywords and find the brand and model you need.
You can also set the battery quantity and add batteries of different models to customise your design.



Input site postcode and proposed installation date.

Select property type. This decides which state incentive will stack with STC.

If your battery is to be installed within 90 days of new panels being installed, select "Yes". You will have a new panels bonus when calculating the combined incentive amount.

Set unit prices for STC and PRC. You may check the dashboard of your retailer portal and find today's price.

Note: This calculator is for estimation only. If you need a specific quotation, please contact your account manager.
Note: Certificate unit prices are variable based on market supply and demand. You can find today's price on your retailer portal.
Note: The incentive amount shown in the calculator is not guaranteed. Every incentive has its own eligibility requirements and factors impacting the final calculation result. The calculator should not replace your assessment on individual jobs.
