What Sunnova offers and how it differs from buying solar panels outright

Sunnova is a solar energy company that installs and owns rooftop solar systems on residential properties. Instead of buying panels yourself, you lease the system from Sunnova or enter a power purchase agreement (PPA) where you pay for the electricity the panels produce. Sunnova handles installation, maintenance, repairs, and equipment replacement for the life of the contract — typically 20 to 25 years.

The core difference from buying: you own nothing. Sunnova retains ownership of the panels, inverter, and all hardware. You pay a monthly lease payment or a per-kilowatt-hour rate for power generated. This structure means no upfront capital cost, no responsibility for repairs, and no need to replace equipment if something fails. It also means you do not claim the federal Investment Tax Credit (ITC) or state tax incentives — Sunnova does, and passes some benefit to you through lower rates.

Sunnova operates in roughly 20 states, though service areas change. You can check their website to see if your address is serviceable. The company also acquires existing solar installations from other providers, so you may receive a notice that your current lease or PPA is being transferred to Sunnova.

Key Takeaways

  • Sunnova owns and maintains the solar system; you pay a fixed monthly lease or a variable rate per kilowatt-hour of electricity produced.
  • No upfront installation cost, no equipment replacement responsibility, and no tax credit claims — Sunnova claims those instead.
  • Contracts run 20 to 25 years and typically include a rate escalation clause that raises your payment 2 to 3 percent annually.
  • You remain responsible for roof repairs; if the roof needs work, Sunnova may require you to pay for panel removal and reinstallation.
  • Sunnova's service area covers roughly 20 states; availability depends on your zip code and local utility regulations.

Lease versus power purchase agreement: payment structure and what you owe

Sunnova offers two main contract types, and the payment model is the primary difference.

A solar lease charges a fixed monthly payment, usually between $100 and $300 depending on system size, location, and local electricity rates. This payment remains the same each month, but most leases include an annual escalation clause — typically 2 to 3 percent per year — so your payment grows over time. After 20 or 25 years, the contract ends and Sunnova removes the system at no cost to you, or you may have an option to renew.

A power purchase agreement (PPA) charges you per kilowatt-hour of electricity your system generates, not per month. The rate is fixed at signing but also escalates annually by a set percentage. Your monthly bill varies based on how much sun your panels receive and how much electricity you use. In a sunny month, your bill is higher; in a cloudy month, it is lower. PPAs appeal to homeowners who want predictability in the rate per unit but accept monthly variation in total cost.

Both structures include maintenance, repairs, monitoring, and equipment replacement. If an inverter fails or a panel degrades, Sunnova replaces it at no cost. You pay only the lease or PPA rate.

What happens to your electricity bill and how much you might save

The savings depend on three factors: your current electricity rate, how much sun your roof receives, and the lease or PPA rate Sunnova quotes you. Sunnova's rate is typically lower than your utility's current rate, which is why the system generates savings. However, utility rates rise over time, and Sunnova's rate also escalates annually, so the gap between what you would pay the utility and what you pay Sunnova narrows as years pass.

Example: if your utility charges $0.14 per kilowatt-hour and Sunnova quotes $0.12 per kilowatt-hour on a PPA, you save $0.02 per unit. But if your utility rate rises to $0.16 and Sunnova's rate rises to $0.13, your savings shrink to $0.03 per unit. Over 20 years, the total savings can range from thousands of dollars to little or nothing, depending on how utility rates move relative to Sunnova's escalation rate.

Sunnova typically provides a savings estimate before you sign. This estimate assumes a specific utility rate trajectory and solar production based on your location and roof characteristics. The estimate is not a may provide — actual results depend on weather, your electricity consumption, and utility rate changes outside Sunnova's control.

Roof responsibility, system removal, and what happens if you sell your home

You remain responsible for the roof itself. If your roof needs repair or replacement, you must pay for it. Sunnova will remove the panels before work begins and reinstall them afterward — you typically pay for this removal and reinstallation, which can cost $1,000 to $3,000 depending on system size and complexity.

If you sell your home, the solar contract transfers to the new owner. Sunnova handles the paperwork, but the new owner assumes all payment obligations for the remaining contract term. Some buyers welcome this; others view it as a liability. If a buyer refuses to assume the contract, you may be required to pay off the remaining balance or have Sunnova remove the system. The payoff amount is typically the net present value of future payments, which can be substantial if many years remain.

At the end of the contract term (20 or 25 years), Sunnova removes the system at no cost. You own the roof and can install a new system, leave it as is, or do nothing. Some contracts include a renewal option at a renegotiated rate; others do not.

How Sunnova's acquisition of existing solar contracts works

Sunnova regularly purchases solar contracts from other companies. If you have an existing lease or PPA with another provider, you may receive notice that Sunnova is acquiring your contract. This means Sunnova becomes your new counterparty — you now pay Sunnova instead of the previous company, and Sunnova assumes responsibility for maintenance and repairs.

The terms of your contract typically remain the same: your payment amount, escalation rate, and contract end date do not change. However, you should review the acquisition notice carefully. Some acquisitions include changes to billing, customer service contact information, or payment methods. If you have questions about the transfer, contact Sunnova's customer service before the acquisition closes.

Acquisitions are common in the solar industry because larger companies consolidate smaller portfolios. From a homeowner's perspective, the main risk is service quality — whether Sunnova's maintenance and billing processes meet your expectations. You can research Sunnova's customer reviews and complaint history before the transfer closes.

Comparing Sunnova to buying panels outright or using other solar companies

If you buy solar panels with cash or a loan, you own the system and claim the federal ITC (currently 30 percent of installation cost) plus any state or local incentives. Over 20 years, ownership typically costs less than leasing if you stay in the home and the system performs as expected. However, you pay for all repairs, replacements, and monitoring out of pocket.

Other solar companies offer similar lease and PPA structures to Sunnova — Sunrun and Vivint Solar are the largest competitors. Rates, contract terms, and service areas vary by company. Getting quotes from multiple providers is the only way to compare actual costs for your address and roof.

Sunnova's main advantage is simplicity: no upfront cost, no maintenance responsibility, and a fixed or predictable payment. The main disadvantage is that you do not build equity in the system and you cannot claim tax credits. If you plan to stay in your home for the full contract term and your utility rates are expected to rise faster than Sunnova's escalation rate, leasing may save money. If you expect to move within 10 years or want to maximize long-term savings, buying may be better.

Service areas, contract terms, and how to get a quote

Sunnova serves approximately 20 states, with the largest presence in California, Texas, Florida, and the Northeast. Service availability depends on state solar regulations, utility interconnection policies, and Sunnova's business decisions. You can enter your zip code on Sunnova's website to check if your address is serviceable.

Standard contract terms are 20 or 25 years. Most contracts include an annual rate escalation of 2 to 3 percent, though this varies. Some contracts allow early termination with a payoff fee; others do not. Read the contract terms carefully before signing — escalation rates and termination clauses differ significantly between quotes.

To receive a quote, visit Sunnova's website or call their sales line. You will need your address, a recent electricity bill (to show current usage and rates), and access to your roof for a site assessment. Sunnova's sales team will estimate system size, annual production, and your projected monthly payment or PPA rate. The quote is typically valid for 30 to 60 days. If you decide to proceed, Sunnova schedules an installation, which usually takes one to three days.

Frequently Asked Questions

What if I want to remove Sunnova's system before the contract ends?

Early termination typically requires paying off the remaining contract balance. This amount is calculated as the net present value of future payments and can be substantial. Some contracts allow guilt-free removal if you sell the home and the buyer assumes the contract; others do not. Review your contract's termination clause before signing.

Does Sunnova's system work during a power outage?

No. Most grid-tied solar systems, including Sunnova's, shut down during outages for safety reasons. If you want power during an outage, you need a battery backup system, which Sunnova may offer as an add-on at additional cost.

Who handles maintenance and repairs?

Sunnova handles all maintenance, repairs, and monitoring. If a panel fails or the inverter malfunctions, contact Sunnova's customer service and they will schedule a repair at no cost. You are responsible only for keeping the roof clear of debris and ensuring the system is not physically damaged.

Can I add more panels to a Sunnova system later?

Typically no. Your contract covers a specific system size. Adding panels would require a separate agreement or contract modification, which Sunnova may or may not allow depending on your roof space and electrical capacity. Ask Sunnova about expansion options before signing the initial contract.

What happens if my roof needs replacement during the contract?

You pay for the roof replacement. Sunnova will remove the panels before work begins and reinstall them after. You typically pay for removal and reinstallation separately, which can add $1,000 to $3,000 to your roof project cost. Budget for this possibility if your roof is aging.
