    3. Share the quote with CommBank and we’ll let you know when your new CommBank Green Loan is approved. You can then instruct your retailer and/or installer to proceed.
    4. Once installation is complete, sign the final invoice and send it to CommBank.

  • What is an Approved Solar Retailer and how can I find them?     

    Approved Solar Retailers have been approved by the Clean Energy Council as demonstrating their commitment to responsible sales and marketing activities and solar industry best practice.

    Find an Approved Solar Retailer near you.

  • What should I do if my Approved Retailer/Installer requires an upfront deposit? 

    If a deposit is required up front, you’ll need to pay this from your own savings.

    We’ll reimburse (pay) the deposit amount into your nominated Direct Debit account for your CommBank Green Loan once we receive the final signed invoice.

  • What should I communicate with my Approved Solar Retailer or Installer regarding payment terms? 

    We’re committed to paying the total outstanding amount directly to your Approved Solar Retailer within 14 days of receiving a verified invoice from you (the customer).

  • Will I need to pay my Approved Solar Installer upon completion of works in order to claim the small-scale technology certificate (STC) rebate? 

    No. The STC rebate can be claimed within 12 months of installation. For any questions regarding customer requirements and STC rebates, please visit the Clean Energy Regulator website.

  • Do I need to verify the brand of solar panel being installed by my Approved Solar Retailer or Installer? 

    As a Clean Energy Council Approved Solar Retailer or Installer, they have committed to conduct their business activities in a responsible manner and in accordance with solar industry best practice. This includes the use of approved solar modules and participating brands.

    For any concerns or complaints regarding your Approved Solar Retailer or Installer, please visit the CEC website. If you have any concerns regarding your consumer rights, please visit the ACCC website for more information or to lodge a complaint.

  • Am I eligible for a CommBank Green Loan if the quote from my installer is less than $5,000?       

    No, the minimum loan amount is $5,000. Get in touch with your Home Lending Specialist to discuss your options.

  • Can I borrow more than $30,000 to install eligible small-scale renewables to my property with a CommBank Green Loan?   

    No, $30,000 is the maximum loan amount. If the cost of the eligible clean energy products installed is more than $30,000, you must pay the difference from your own savings before we can make a payment to the installer.

    So if, for example, the total cost for your project is $35,000 and you’ve been approved for the maximum loan amount of $30,000, you’ll need to pay the difference of $5,000 from your own savings.

  • Can I apply for a CommBank Green Loan if I already have an existing eligible small-scale renewable(s) installed? 

    If you wish to upgrade your existing small-scale renewables (by adding a battery pack or more solar panels, for example), you may be eligible for a CommBank Green Loan.

  • Does the minimum outstanding balance of $150,000 (on my CommBank home loan) include redraw?

    No. The loan balance that we use for eligibility is the outstanding balance you see in NetBank or the CommBank app. The calculation of minimum $150,000 also excludes, loans for bridging purposes, Viridian Line of Credit limits, Equity Unlock for Seniors loan and the new CommBank Green Loan.
