The terms behind your solar agreement.

These are the Terms and Conditions of Sunnn Pty Ltd (ABN 94 690 774 317) referred to in your solar proposal and agreement. They apply to the supply and installation of a solar PV and/or battery system (the System) at your premises.

These are not new terms. The payment, price, STC and handover terms below are the arrangements that have applied to our agreements all along, set out here in full so they are clear and in one place. This page was published on 11 August 2026. Where we change the wording, the version current when you signed is the version that applies to your agreement.

If anything here is inconsistent with the agreement you signed, your signed agreement prevails. Nothing in these terms limits your rights under the Australian Consumer Law, and we are bound by the New Energy Tech Consumer Code (NETCC).

1. Payment terms and when the balance falls due

A payment equal to fifty per cent (50%) of the total System price is payable before installation begins, and is applied toward the total agreed amount. We will issue a receipt for every payment you make.

The remaining balance falls due on completion of installation and commissioning of the System. We will issue an invoice for the balance once the System is installed and operational, and that invoice is payable within seven (7) days of issue unless we have agreed different terms with you in writing. We will not require final payment before your System is installed and operational.

Where you have arranged finance or a deferred payment arrangement through a third-party credit provider, payment is governed by your agreement with that provider, and the balance falls due in accordance with it.

If an amount remains unpaid after its due date, we may charge interest on the overdue amount at the rate fixed from time to time under the Penalty Interest Rates Act 1983 (Vic), calculated daily from the due date until the amount is paid. We will always contact you before charging interest, and if you are having trouble paying, tell us: we will work with you on a payment arrangement.

2. Payment security and retention of title

Ownership of the System does not pass to you until we have received payment in full of all amounts owing under your agreement. Until then the System remains our property, even once it has been installed at your premises, and you agree that it does not become a fixture or part of your land while we still own it.

Risk in the System passes to you on completion of installation and commissioning. Until we have been paid in full, you agree not to sell, transfer, remove, encumber or grant any security interest over the System, and to tell us promptly if anyone else claims an interest in it. If the System is installed at premises you do not own, you confirm you have the owner’s consent to the installation.

These terms create a security interest in the System in our favour under the Personal Property Securities Act 2009 (Cth) to secure payment of the amounts you owe us. You consent to us registering that security interest on the Personal Property Securities Register and agree to provide any information we reasonably need to do so.

The security is over the System only. We do not take, and will not register, any security interest, mortgage or charge over your home or your land.

If an amount remains unpaid after its due date and is not paid within 14 days of us giving you written notice, we may recover the amount as a debt due to us, together with our reasonable costs of recovery. We may also recover the System where the law entitles us to do so. Any entry to your premises for that purpose will be at a reasonable time, on reasonable prior written notice, and only with your consent or under a court order. Nothing in this section limits your rights under the Australian Consumer Law, and we will comply with the notice, hardship and dispute obligations that apply to us, including under the New Energy Tech Consumer Code.

3. When the price may change

The price in your agreement is the price you pay. It may only change in the following circumstances, and in each case only where we have quoted the change and you have agreed to it in writing before the work proceeds:

• Additional works identified at your site, for example a switchboard or meter upgrade, non-standard mounting, asbestos, or other pre-existing or unforeseen site conditions identified by the installer.
• Changes to the System or scope that you ask us to make.
• Works required by your electricity distributor or an electrical authority that are outside the scope of your agreement.

If you do not accept a proposed change, you may terminate the agreement and receive a full refund of amounts paid, in accordance with your cancellation rights below.

4. STCs and assignment

The price in your agreement is shown net of the Small-scale Technology Certificate (STC) discount. Under your agreement you assign to us the right to create and claim all STCs associated with the System and its installation, and you agree to sign the assignment paperwork required by the Clean Energy Regulator. The STC discount is our consideration for that assignment.

STCs are administered by the Clean Energy Regulator and eligibility is set by that scheme, not by us. If the assignment cannot be completed because your premises or installation is not eligible under the scheme, we will tell you before installation proceeds and you may either accept a revised price that removes the STC discount or terminate the agreement and receive a full refund of amounts paid.

5. Maintenance Documents

Once the System is installed and commissioned we will provide you with:

• operating instructions and the user manual for your System;
• the manufacturer warranty documents for your panels, inverter and (where installed) battery;
• a recommended maintenance schedule, including servicing intervals and what each service covers;
• system shutdown and isolation procedures, and what to do in an emergency;
• your Certificate of Electrical Safety or equivalent compliance certificate for the installation;
• details for accessing your system monitoring; and
• end-of-life disposal guidance, including that batteries must not be placed in household waste and should be collected by a licensed battery recycler or returned via the manufacturer.

6. Cancellation, cooling-off and refunds

If your agreement resulted from unsolicited contact by us, you have a 10-business-day cooling-off period from the day after you sign, during which you may cancel without penalty and receive a full refund of any deposit paid. You may also cancel at any time before installation commences; if you cancel outside any applicable cooling-off period we may retain only our reasonable costs actually incurred and will refund the balance of any amounts paid.

Your agreement also sets out circumstances in which you may terminate and receive a full refund, including a significant change to the installation design, unforeseen site conditions producing additional chargeable work we are unwilling to absorb, and our failure to meet a delivery and installation timeframe specified in the contract for reasons within our control.

7. Grid connection and metering

Although we may assist in arranging connection of the System to the grid and installation of your meter, that connection and installation is an agreement between you and your electricity retailer and/or distributor. Its costs and risks are not included in your agreement with us, and your retailer may change your electricity contract or tariff as a result of the installation.
