HOUSTON–(BUSINESS WIRE)–Sunnova Energy International Inc. (NYSE: NOVA) announced today the launch of the industry’s first 0% APR financing¹ for home solar and battery storage service with 25-year system protection. New Sunnova customers may now be eligible to go solar for as low as 0% APR and $0 down with the purchase of a new Sunnova SunSafe® solar + battery storage system, or .99% APR and $0 down for the purchase of solar-only service. Sunnova provides its exclusive 25-year Sunnova Protect™ limited warranty service coverage for each solar + storage customer, offering worry-free maintenance, monitoring, repairs, and replacements to help ensure each home solar investment perform to its maximum potential.²

“We are thrilled to be able to offer such competitive financing in the solar service industry,” said Michael Grasso, Chief Marketing Officer of Sunnova. “In addition to these historically low APRs³, this financing solution will allow new customers to take advantage of the 26% federal tax credit⁴ and state incentives while uniquely enjoying 25 years of Sunnova Protect™ coverage on their solar or solar + battery systems, and greater control over their energy costs.”

“We are focused on knocking down barriers that prevent homeowners from purchasing a clean and affordable energy system from a trusted service provider, like Sunnova,” said William J. (John) Berger, Chief Executive Officer of Sunnova Energy International. “Alongside our Lease and PPA (power purchase agreement) service offerings, this new APR offering will help address a real need in the marketplace and will further increase our industry-leading growth rate.”

During a power outage, Sunnova SunSafe® provides resilient backup power so homeowners can run their essential appliances. Unlike a solar-only system, Sunnova SunSafe® produces solar energy during the day and sends excess energy to the rechargeable battery for use at night, or anytime it’s needed.⁵ During the installation process, solar dealers will conduct an extensive review of the home and build an efficient home solar system – with battery – tailored to each consumer’s energy needs and budget. Sunnova only uses industry-leading, vetted battery technology like the Generac PWRcell™, Tesla Powerwall, and the recently announced Enphase Encharge™ storage system. All home solar and battery systems are covered by Sunnova Protect™⁶ featuring worry and hassle-free maintenance, monitoring, repairs, and replacements.

⁴ Customers may be eligible for a federal tax credit with the purchase of a solar system. To qualify for the tax credit, you must have federal income tax liability at least equal to the value of the tax credit. Additional tax credits may also be available for homeowners in certain states. Tax incentives are subject to change or termination by executive, legislative or regulatory action. Sunnova makes no guarantees regarding eligibility of any of the system’s costs for tax benefits. Sunnova does not provide tax advice. Contact your personal tax advisor for eligibility requirements.

⁵The amount of power available from the battery during a power outage is limited, depending on the loads connected, customer usage and battery configuration (i.e. batteries in certain areas may be set up to provide you with the best economic benefit, which may affect the amount of back-up power available). Solar systems and/or batteries may require repairs after weather events and such repairs may be delayed due to forces outside of our control. No assurances can be given that the solar system or the battery will always work. You should never rely upon either of these to power life support or other medical devices.
