Sunrun in Connecticut: an honest look before you sign

Sunrun is the biggest name in residential solar, and plenty of Connecticut homeowners get a Sunrun pitch. This page isn't a takedown and it isn't a sales sheet. It's the stuff we'd want our own family to understand first: the company's finances, how its lease and PPA really work here, and what to do if things go sideways.

SolarPro Lab is an independent marketplace. We match you with vetted installers and help you compare. We don't install panels, and we're not affiliated with Sunrun.

Most homeowner regret with a big national installer doesn't come from the panels. It comes from the paperwork: a 20-year agreement, an escalator that quietly raises the payment every year, and a buyout clause nobody read closely. So let's start there.

Sunrun's corporate financial health

Sunrun is the largest residential solar and storage company in the United States and trades publicly on Nasdaq under the ticker RUN. It reported more than one million customers as of December 31, 2024.[1] For a homeowner, the upside of working with a company that size is scale: a lot of installs, a financing operation, and a service arm that should still be there years from now.

The honest part is that Sunrun's subscription model is capital-intensive, and the company has posted large accounting losses. In the fourth quarter of 2024 it reported a net loss attributable to common stockholders of about 2.8 billion dollars, driven mostly by a non-cash goodwill write-down of roughly 3.1 billion dollars rather than by day-to-day operations.[1] It ended 2024 with about 947 million dollars in total cash.[1]

More recently the picture steadied. Through the third quarter of 2025 Sunrun reported its sixth straight quarter of positive cash generation, with about 108 million dollars of cash generation in that quarter, and guided to 200 to 500 million dollars of cash generation for full-year 2025.[2] None of this is investment advice. The point for a homeowner is simpler: a public company files real numbers you can check, and a big balance sheet is reassuring but it isn't a substitute for reading your own contract.

What this means for you: Sunrun being large and public is a point in its favor on staying-power. It doesn't change the math on a 20-year lease or PPA. Judge the deal in front of you on its own terms.

Connecticut sued Sunrun in 2024

If you're weighing a Sunrun offer in Connecticut, you should know the state has taken Sunrun to court. On July 19, 2024, Attorney General William Tong sued Sunrun Inc. and Sunrun Installation Services, along with two sales and marketing firms, Bright Planet Solar and Elevate Solar Solutions, and two salespeople, alleging deceptive, unfair, and unlawful sales of solar panel systems.[4]

The allegations are specific. The complaint accuses the defendants of locking consumers into long-term contracts without their consent, impersonating consumers, forging signatures on lease agreements, installing panels without the required permits, failing to disclose material terms such as a 2.9 percent annual payment increase, and in some cases installing systems that were never activated. The state brought the case under the Connecticut Unfair Trade Practices Act and the Home Improvement Act, and is seeking restitution, civil penalties, and an order stopping the conduct.[4]

Two things matter for how you read this. First, these are allegations. As of the state's March 2026 update the Sunrun case was still active and unresolved, not a finding of liability, and a national company can be sued over the conduct of the marketing and sales firms operating under its name.[5] Second, the same update shows Connecticut is policing the whole industry, not just Sunrun: the Attorney General opened a fresh investigation into a solar-contract manager after roughly 65 complaints, and settled a separate matter with another company for 100,000 dollars.[5]

What this means for you: A national brand name is not a substitute for reading the contract and checking who's actually selling to you. Many of the alleged problems trace back to high-pressure third-party sales, the exact model we screen against. Get the agreement in writing, confirm the permits, and put a Sunrun offer next to a vetted local installer before you sign anything.

Lease vs PPA: what they really are in CT

Sunrun's two most common offers are a lease and a power purchase agreement. They sound similar and the sales conversation often blurs them, but they bill you differently.[3]

Lease

You pay a fixed monthly amount to use the system, no matter how much sun you get that month. Predictable bill, but you carry the cost even in a cloudy stretch.

PPA

You pay a set price for each kilowatt-hour the panels actually produce. Your bill tracks production, so a weak solar month costs less and a strong one costs more.

Three things are true of both, and they're the parts homeowners miss:

  • The term is usually 20 years. That's a long relationship with one company.
  • Both can carry an escalator, often around 1.5 to 3 percent a year. At 2.9 percent, the payment is roughly 70 percent higher in year 20 than in year 1.
  • Sunrun owns the panels, not you. The system is the company's asset on your roof, which is what makes the third-party-ownership tax structure work.

In Connecticut there's one more wrinkle. The state retired legacy net metering and replaced it with the Residential Renewable Energy Solutions (RRES) program, which has two tariff options with different economics. On a third-party-owned system, confirm in writing which RRES tariff applies and who keeps the bill credits. We walk through how RRES works in our Connecticut RRES net metering guide.

If you're still weighing financing structures, our lease vs buy in Connecticut breakdown compares a lease and PPA against cash and a loan, including where the 2026 Section 48E prepaid-lease structure fits.

What to ask before you sign

Bring these six questions to any Sunrun conversation. A good rep answers all of them in writing without flinching. If you get pushback, that's information too.

1
Is this a lease, a PPA, a loan, or a cash purchase?
These are four very different deals. A lease and a PPA mean Sunrun owns the panels and you don't get the system as an asset. Know which one you're being offered before anything else.
2
What is the annual escalator, and what does year 20 cost?
A payment that rises 2.9 percent a year is roughly 70 percent higher by year 20. Ask for the full payment schedule in writing, not just the first-year number.
3
What is the production guarantee, and how do I get paid if the system underproduces?
A guarantee is only worth the claim process behind it. Get the kilowatt-hour target and the exact steps to file a shortfall claim.
4
What does an early buyout cost in years one through five?
Buyouts priced at fair market value can be expensive early on. If you might move, this number matters more than the monthly payment.
5
How does net metering work for me under CT's RRES program on a third-party-owned system?
Connecticut replaced legacy net metering with RRES. Confirm in writing which tariff applies and who keeps the bill credits.
6
Who services the system, and what's the response time on a real problem?
On a 20-year agreement, service matters more than the install. Ask who answers the phone in year seven.

What to do if Sunrun stops operating

Sunrun is large and, as of its 2025 filings, generating cash, so this isn't a prediction. But it's a fair question to ask of any company you're signing a 20-year deal with, especially after more than 100 solar companies failed across the industry in 2024.

Here's the reassuring part of a third-party-owned system: your contract and the panels are financial assets. If the company that holds them goes under, those agreements are usually sold or transferred to another operator, so the panels keep running and your payments simply go to whoever now holds the agreement. The thing that tends to suffer is service, longer waits, harder-to-reach support, and slower warranty claims.

Protect yourself the same way regardless of installer: keep your own copies of the signed agreement, the production guarantee, the equipment warranties, and the monitoring login. We lay out the full playbook, including how warranties and service obligations survive a failure, in our guide:

Want to compare Sunrun against local CT installers?

A national quote is a data point, not a decision. The best way to know whether a Sunrun lease or PPA is right for you is to put it next to a couple of vetted Connecticut installers and compare the equipment, the ownership structure, and the 25-year math side by side.

That's what we do. SolarPro Lab matches you with vetted installers from our roster and helps you read the fine print. You pick who you work with. We never sell your information, and the referral fee we earn is flat across every installer, so there's no reason for us to steer you.

Frequently asked questions

Is Sunrun a financial risk for Connecticut homeowners?

Sunrun is the largest residential solar and storage company in the United States and trades publicly on Nasdaq as RUN, with more than one million customers as of the end of 2024. It has reported large GAAP net losses in the past, including roughly a 2.8 billion dollar net loss in the fourth quarter of 2024 that was driven mostly by a non-cash goodwill write-down. In 2025 it reported six straight quarters of positive cash generation. A homeowner's bigger exposure is usually the 20-year contract itself, not next quarter's earnings, so read the agreement first.

Is Sunrun being sued in Connecticut?

Yes. On July 19, 2024, Connecticut Attorney General William Tong sued Sunrun and two affiliated sales and marketing companies, alleging deceptive and unlawful solar sales practices that included forging signatures, locking consumers into contracts without consent, failing to disclose material terms, and installing systems without permits or that were never activated. The case was brought under the Connecticut Unfair Trade Practices Act and the Home Improvement Act, and it was still active and unresolved as of the state's March 2026 update. These are allegations, not a finding of liability. A homeowner's best protection is still to read the contract and verify who is actually selling to them.

What is the difference between a Sunrun lease and a Sunrun PPA?

With a lease you pay a fixed monthly amount to use the system. With a power purchase agreement, or PPA, you pay a set price for each kilowatt-hour the panels produce. Both are typically 20-year agreements, both can include an annual escalator that raises your payment around 1.5 to 3 percent per year, and in both cases Sunrun, not you, owns the panels on your roof.

Do I own the solar panels with a Sunrun lease or PPA?

No. Under a lease or PPA the system is owned by Sunrun or its financing partners. You're paying for the use of the equipment or the power it makes, not buying it. Ownership only comes into play if your contract includes a buyout, and a buyout priced at fair market value can be expensive in the early years.

What happens to my Sunrun agreement if I sell my house in Connecticut?

A leased or PPA system stays with the home, so your buyer generally has to qualify and assume the remaining contract, or you pay it off at closing. Sunrun offers a service-transfer process, but the agreement can still become a negotiating point with buyers who don't want to take on someone else's 20-year solar contract.

What happens if Sunrun stops operating?

With a third-party-owned system your contract and the equipment are assets that would typically be sold or serviced by another company, so the panels usually keep running and your payments continue to whoever holds the agreement. The real risk is slower service and harder-to-reach support. Keep copies of your contract, production guarantee, and warranties, and read our guide on protecting yourself if a solar company goes bankrupt.
