After the job is finished by your installer, it is ready to submit to the STC team via GreenDeal. Once lodged, the STC team will notify you the progress or current status of the particular job.


Our STC team will finish processing your jobs in 18 hrs.


Your credit/cash will be ready after the STC is processed.

STC cash trade

We recognise that there are times when companies simply wish to take the current STC price and convert it to cash (at a discounted rate). With one the most competitive STC prices on the market today we recognise the logic in this option, particularly for those who are primarily focused on generating cash to fund the next job. At the end of the day, logic always prevails.

STC credit trade

This solution was developed to provide customers with the opportunity to trade STC’s for equipment and streamline the whole procurement process. Dealing with one company for all of your solar needs simply makes sense. We are an experienced distributor with a wide range of quality products and packages. You will have the perfect solution to manage your stock needs.

Trading Information

For cash trade, cash will be paid into your account once your STC job got REC Registry's approval.(Normally, 7 days from you received the qualification notice from STC team. Can be up to 4 weeks depends on REC arrangement.) Or in the case of equipment, your account will be credited in 1 - 3 business days.

    How will your equipment STC’s be allocated?
  • STC’s will be allocated first to the oldest outstanding invoice if you are a terms customer.
  • Or to balance of orders where the deposit has been paid.
  • Remaining STC will remain as a credit on the account until it can be allocated to new orders where the deposit has been paid.
