How to cancel your sunnova solar contract and reclaim your rights

Why you might want to cancel your sunnova agreement

Sunnova operates as an energy-as-a-service provider, meaning you're not buying a solar system outright-you're locked into a long-term contract, often spanning 20 to 25 years. If your circumstances have changed, you've moved house, found a better energy deal, or you're frustrated with performance or customer service, cancellation becomes necessary.

The challenge is that Sunnova contracts are complex, often bundling financing, power purchase agreements, warranties and maintenance into one multi-year commitment. At Stopee, we've helped thousands of Australian homeowners navigate the cancellation process for solar contracts, and we know that early exit comes with real obstacles-financial penalties, unclear terms and slow response times.

Understanding your options now puts you in control.

Common reasons australian homeowners cancel

You might cancel because you're relocating interstate or overseas, selling your home, switching to another provider, disputing production guarantees, or simply wanting to exit an unfavourable long-term agreement. Some customers discover their system underperforms or face unexpected repair costs outside warranty. Others refinance or restructure their finances and need to free up monthly obligations.

What you'll face during the cancellation process

Sunnova contracts rarely offer simple exit clauses. You'll typically encounter notice periods, early termination fees, settlement calculations, and administrative delays. Response times can stretch beyond 30 days, and you may need to escalate disputes through multiple channels before reaching a resolution.

Your consumer rights under australian consumer law

Australian Consumer Law protects you even when you've signed a long-term solar contract.

The Australian Consumer Law Act 2010 (ACL) grants you statutory rights regardless of contract length. You have the right to services rendered with due care and skill, goods fit for purpose, and transparent pricing. If Sunnova's system fails to deliver the performance or output promised in marketing materials or the contract, you may have grounds for a claim or cancellation on consumer protection grounds.

Cooling-off rights and when they apply

For most consumer contracts, you have a 14-calendar-day cooling-off period from the date of signing. However, if your Sunnova agreement qualifies as consumer credit or a finance contract, the cooling-off window may be different or absent entirely. Check your original contract to confirm whether a cooling-off clause exists and whether you fall within the timeframe.

Pro tip: If you signed within the last 14 days and no cooling-off clause was provided in writing, contact Sunnova immediately in writing to invoke your statutory right to cancel.

Your rights to dispute poor performance or misleading claims

If Sunnova promised a specific energy output and the system consistently underperforms, you may have a claim under the ACL for misleading or deceptive conduct. Collect 12 months of production data, compare it to the contract guarantees, and document the shortfall. This becomes your evidence if you escalate to the Australian Securities and Investments Authority (ASIC) or your state-based consumer regulator.

Cancellation methods and which one is right for you

Sunnova doesn't offer a simple online cancellation portal or customer service phone line for exit requests.

Your primary cancellation route is postal communication to Sunnova's registered office. This creates a paper trail and ensures your request is formally documented. You may also attempt phone contact first to understand your financial settlement, but follow up all conversations with written confirmation.

Written postal cancellation

Sending a formal cancellation letter by tracked post is the most reliable method. This approach creates legal documentation, proves date of receipt, and establishes a clear audit trail if disputes arise.

Phone contact as a first step

Before posting your cancellation letter, call Sunnova to ask for clarification on early termination fees, settlement calculations, and the formal cancellation process. Ask for the name of the person you speak with, the date and time of the call, and request they email you a summary. This prepares you for written follow-up.

Email follow-up and escalation

If Sunnova has a customer service email address, send your cancellation request electronically as well. Include a subject line: "Formal Cancellation Request - Account [Your ID]". Email creates a secondary evidence trail and sometimes triggers faster internal responses than post alone.

Step-by-step cancellation process

Follow these steps to cancel your Sunnova contract and protect your interests.

1. Gather your contract documents and account information
   • Locate your original Sunnova agreement and any amendments
   • Find your system ID, account number and customer reference number
   • Collect 12 months of production data from your monitoring portal
   • Screenshot any performance discrepancies or service issues
2. Calculate your financial position
   • Review the contract for early termination fees or exit clauses
   • Check for any outstanding finance balance or PPA settlement amount
   • Note the contract start date and remaining term
   • Request a settlement quote from Sunnova before sending your cancellation letter
3. Draft your formal cancellation letter
   • Address it to the Sunnova office listed in your contract or on their website
   • State your full name, address and system ID clearly at the top
   • Include the date you want the cancellation effective (typically 30 days from posting)
   • Reference the contract date and your account number
   • Keep the tone professional and factual-avoid emotional language
   • Request written confirmation of cancellation within 14 business days
4. Send your letter via tracked postal service
   • Use Australia Post Registered Mail or a courier service with tracking (Australia Post Parcel Delivery or StarTrack)
   • Send to the address provided in your contract or confirmed by phone
   • Pay for a signature-on-delivery option to prove receipt
   • Keep your receipt and tracking number permanently
5. Follow up in writing within 10 days
   • Email your cancellation request to customer service with the same details
   • Include your tracking number and the date you posted the letter
   • Request an email confirmation of receipt
6. Monitor your account and follow up after 14 business days
   • Check your email and post for Sunnova's written response
   • If no response arrives, send a follow-up letter marked "Second Notice"
   • If still no response, contact the Office of the Ombudsman or your state-based consumer regulator

Warning: Do not simply stop paying invoices or assume cancellation has occurred by silence. Sunnova may report non-payment to credit agencies or pursue debt recovery. You must receive written confirmation before ceasing payment.

Understanding your financial settlement

Cancelling a Sunnova contract early typically triggers financial obligations that you need to calculate before requesting exit.

Early termination fees and exit costs

Most Sunnova agreements include early termination fees if you cancel before the end of the initial contract term. These fees vary by contract type-a 20-year power purchase agreement will charge differently than a financed ownership plan. Your contract schedules should specify the formula: common structures include a flat fee, a percentage of remaining payments, or a stepped reduction based on years remaining.

Pro tip: Request Sunnova provide a formal settlement statement in writing before you send your cancellation letter. This gives you certainty and prevents disputes later.

Outstanding financing or PPA balance

If you financed your system through Sunnova or are on a power purchase agreement, you owe the outstanding balance. Sunnova will calculate this as the net present value of remaining payments. You must settle this amount in full to fully cancel and release your system from their lien.

Proration and final billing

Your final invoice will be prorated to the effective cancellation date. If you paid in advance or if Sunnova charges monthly in arrears, your final bill may include credits or additional charges depending on the exact exit date you choose. Request itemised billing to verify every line.

Warranty and system ownership after cancellation

Once you cancel, confirm what happens to the system warranty, monitoring access, and maintenance obligations. Some contracts transfer full ownership to you upon settlement, while others require Sunnova to remove the system or retain a lien until final payment clears. Get this in writing before the cancellation is final.

What happens after your cancellation is processed

Cancellation is a milestone, not an ending-you have important steps to complete afterwards.

Confirming cancellation and updating utilities

Once Sunnova confirms your cancellation in writing, check that your electricity account reflects the change. If you were on a Sunnova power plan, contact your network provider to update your meter status. Request confirmation that the system is no longer linked to your account and that future bills do not reference Sunnova billing or a PPA.

Removing system monitoring and access

Ask Sunnova for confirmation that your system monitoring portal access has been deactivated. Obtain final production and performance reports for your records. If you want ongoing monitoring, transition to a third-party monitoring platform or contact the system manufacturer directly.

Managing ongoing electricity costs

After cancellation, you're responsible for your full electricity consumption. Review your usage history and contact your energy retailer to explore whether standard solar customer rates or time-of-use tariffs suit your new circumstances. You may also consider a second solar installation or battery system from another provider if you wish.

Common mistakes that delay or derail cancellation

Cancellations often stall because customers make preventable errors early in the process. Learning what not to do saves you weeks of frustration.

Not documenting everything in writing

Phone calls with Sunnova customer service create no binding record. If a representative promises something-a fee waiver, a faster exit date, or a settlement adjustment-follow up with an email repeating what was agreed. Without written proof, you have no recourse if Sunnova changes its position later.

Missing the tracking proof of your postal letter

Sending your cancellation letter via ordinary mail is risky because Sunnova can claim non-receipt. Always use tracked post with signature confirmation. Store your receipt number permanently and reference it in all follow-up communications.

Agreeing to payment plans you can't afford

If Sunnova's settlement amount is high, don't rush into a multi-month payment plan. Negotiate the best lump-sum settlement first. If you genuinely need a payment plan, ensure it's in writing with a fixed end date and no interest charges.

Assuming silence means approval

Sunnova's lack of response does not cancel your contract. You must receive explicit written confirmation of cancellation and the effective date. Silence gives them time to delay while your obligations continue.

Stopping payments before final settlement is confirmed

Never cease payments until Sunnova sends written confirmation that your contract is cancelled and all balances are settled. Early payment stoppage can damage your credit rating and trigger debt recovery action.

Pricing, fees and what cancellation will cost you

Sunnova cancellation costs vary dramatically depending on your contract type, age and remaining term.

Pro tip: If you're still within the cooling-off period, cancellation is free. Check your contract signing date immediately-if you're within 14 calendar days, invoke your right to cancel at no cost.

Escalation: what to do if sunnova refuses to respond

If Sunnova ignores your cancellation request or refuses a reasonable exit, you have consumer escalation channels in Australia.

Contacting the office of the ombudsman

The Energy and Water Ombudsman (EWO) in your state handles disputes with energy retailers and solar service providers. You can lodge a complaint at no cost if Sunnova fails to respond within 21 calendar days or if you dispute their settlement calculation. The Ombudsman can force Sunnova to review their position and mediate a resolution.

Reporting to ASIC or the ACCC

If Sunnova engaged in misleading conduct (such as overstating system output or hiding early termination fees), report them to the Australian Securities and Investments Authority (ASIC) or the Australian Competition and Consumer Commission (ACCC). These agencies investigate systemic complaints and can take enforcement action.

Engaging a specialist lawyer

If the settlement amount is contested or the contract is genuinely unfair, consider seeking advice from a consumer law specialist or solar contract lawyer. Many offer free initial consultations and work on a no-win-no-fee basis for disputes involving misleading solar claims.

Warning: Do not engage in legal action until you've exhausted Ombudsman and regulatory complaint channels-those routes are faster and cheaper.
