Cancellation Sunnova: Step-by-Step Guide

What is Sunnova

Overview

Sunnova is a U.S.-based residential solar company that offers installation, monitoring, maintenance and financing options for rooftop solar systems. Their business model commonly includes long-term contracts such as leases, power purchase agreements (PPAs) and loans.

Business model and contracts

Many Sunnova agreements are long-term (commonly 20 - 25 years) and tie solar equipment and service obligations to the property or the named customer. Contracts commonly include operational guarantees, payment schedules and transfer or buyout provisions.

How to cancel Sunnova

Immediate steps

• Check your contract for any rescission/cancellation clause and the signing date.
• Determine if you are still inside a short “rescission” or cooling-off window (if applicable).
• Contact Sunnova customer service and request written confirmation of cancellation terms and buyout figures.

Formal cancellation actions

• Send written notice of cancellation by certified mail to Sunnova’s legal address (keep copies and proof of delivery).
• Request a formal buyout quote (present value of remaining payments) if you plan to exit early.
• If selling your home, discuss contract transfer options with Sunnova and any buyer requirements.
• If you believe you were misled or the company failed to perform, consider filing a regulator complaint and seeking legal advice.
• For a practical how-to, see a consumer guide: Cancel Sunnova - guide.

What happens when you cancel

Service and access

After cancellation or termination, access to Sunnova’s monitoring and maintenance may end unless the agreement is transferred or a buyout is completed. Service continuity depends on contract terms and whether equipment remains on-site.

Financial and contractual consequences

Early termination commonly triggers a buyout equal to the present value of remaining payments and may include additional administrative, design or permitting fees.

Failure to follow contract procedures can result in default notices or collection actions; get written figures before stopping payments.

Will I get a refund?

General refund policy

Sunnova’s financing, lease and PPA agreements do not operate like retail refunds. After any short rescission period, there is typically no refund; instead, termination involves buyout or termination costs.

Possible exceptions

• If you cancel within a valid rescission/cooling-off window, you may be able to void the contract without buyout fees (contract- and jurisdiction-dependent).
• If Sunnova materially breaches performance obligations, remedies can include dispute resolution, complaints to regulators, or legal action rather than a simple refund.
• For details on cancellation scenarios, see: consumer cancellation guide.

Sunnova plans and pricing

Where to check official pricing

Do not rely on third-party estimates for Sunnova pricing. Check Sunnova’s official materials and contract documents for exact terms and pricing.

Singapore availability

There is no evidence that Sunnova offers standard pricing or operates in Singapore as of the available sources. Local solar pricing in Singapore is provided by local vendors instead.

Your consumer rights in Singapore

Local consumer law

Singapore consumer protections include the Consumer Protection (Fair Trading) Act and the Lemon Law for certain products and services. Whether these apply to a foreign company depends on how and where services are offered.

Remedies and complaints

If Sunnova does not offer services in Singapore, local consumer law may not apply. If you believe you were misled by a provider operating in Singapore, consider contacting local consumer authorities or legal counsel for jurisdictional advice.

Customer experiences

Positive reports

Some customers have reported smooth installations, helpful staff and functioning maintenance plans in reviews.

Positive feedback is reflected in a subset of online reviews and service experiences.

Negative reports

Frequent negative themes include unresponsive customer service, delays or failures to repair/activate systems, billing for non-producing systems, and disagreements over promised energy production.

Concerns about review authenticity and complaints records have also been raised; see sample reports and reviews for context: Trustpilot reviews and documented complaints.

Documentation checklist

Contract and signing documents

• Full signed contract and any addenda or amendments.
• All signature pages with dates and witness information.
• Any rescission or cooling-off disclosures in writing.

Technical, financial and communication records

• Invoices, payment records and bank statements.
• Production guarantees, monitoring screenshots and system performance logs.
• Photos of the installation, damage evidence, permits and inspection reports.
• All written communications (emails, letters, chat transcripts) with Sunnova and installers.

Common mistakes

Underestimating contract length and obligations

Many customers underestimate how long solar leases or PPAs last and the cost to exit early. Contracts are often 20 - 25 years and require buyouts or transfers to leave early.

Failing to document performance and communications

Not keeping records of outages, production shortfalls, or repair requests weakens disputes. Always document issues with dates, photos and written follow-ups.

Next practical steps

Confirm in writing that services have ended, obtain final account statements, and secure records showing the cancellation or settlement of obligations.

If equipment remains, decide who is responsible for maintenance, insurance and removal under your contract terms.
