Sunrun reviews are split: the company is the largest U.S. residential solar provider and many owners like their systems, but a large share of reported complaints involve billing, slow service and sales promises. On SolarReviews the average is 2.88 stars across 3,660 reviews, while the Better Business Bureau shows an A+ rating alongside thousands of filed complaints. This guide separates what owners praise from what they report, so you can judge a Sunrun proposal on its terms.

What Sunrun sells and how it works
Sunrun mostly does not sell you panels outright. Its annual report describes its core offerings as leases and power purchase agreements, with customer agreements that "typically have an initial term of 20 or 25 years." Rates can be fixed or can rise by a set percentage each year. At the end of the term you can renew (typically at a 10% discount to then-prevailing power prices, per the filing), buy the system at fair market value, or have it removed. The company says it has more than one million customers.
That structure matters when you read reviews. A lease or PPA is a 20-to-25-year relationship with one company, so service quality, billing accuracy and contract terms count for more than they do with a one-time purchase.
What owners praise
- Little or no upfront cost. Lease and PPA customers avoid a large cash outlay or loan.
- Install crews. Reviewers on SolarReviews often describe crews as friendly, professional and tidy.
- Maintenance is Sunrun's problem. Under a lease or PPA the company owns the equipment and is responsible for repairs.
- Battery installs. Some reviewers report good experiences with Powerwall 3 additions.
What owners report as problems
Complaints on SolarReviews cluster in a few areas. These are reviewer-reported experiences, not findings of fact, and Sunrun responds to many of them publicly.
- Slow repairs. Reviewers cite parts delays and canceled appointments for inverter and battery replacements.
- Hard-to-reach support. Some say cases are escalated repeatedly without resolution.
- Billing errors. Duplicate charges and auto-draft disputes come up.
- Roof work. Panel removal and reinstallation after a roof replacement, and who pays for it, is a recurring sore spot.
- Underperformance and sales claims. Some owners say savings or system sizing were described more favorably than what they got.
Reviewers also mention fees and escalators, such as a 3% annual increase on one 25-year lease. Treat individual reviews as prompts for questions to ask, not as a pricing guide.
Sunrun reviews by the numbers
| Source | What it shows | How to read it |

| SolarReviews | 2.88 average from 3,660 reviews; about 54% one-star, about 38% five-star | Polarized. Unhappy customers are more likely to post. |
| Better Business Bureau | A+ rating, accredited since 2009; 4,059 complaints filed in 3 years, 1,279 in the last 12 months | The letter grade reflects how the company responds, not how many complaints arrive. Scale matters for a company with a million customers. |
| Company filing (FY2025 10-K) | 8,404 MW networked capacity; California is over 45% of its customer base | Size gives staying power, but local service varies by region. |

The Connecticut settlement
In October 2026 the Connecticut Attorney General announced settlements resolving a 2024 lawsuit against Sunrun, a sales contractor called Elevate and two salespeople. The state had alleged deceptive and unlawful solar sales, including locking consumers into long-term contracts without consent. Sunrun agreed to pay $300,000 to the state, notify affected customers, investigate fraud claims and offer relief such as credits, cancellation or system removal where fraud is substantiated. The defendants did not admit liability. The case is a useful reminder that who is standing in your living room matters: many large providers use third-party sales contractors.
Is Sunrun a good solar company?
It depends on the contract in front of you. Sunrun has scale, a long operating history and a formal escalation channel. It also carries a high volume of complaints, and lease and PPA terms can be hard to compare with a purchase. After 2025, the federal 25D credit for homeowner-owned systems is gone, so third-party ownership is a larger share of the market. Providers that own the system may still claim a federal business credit and can pass some value through lower rates, but you should confirm that in writing.
Questions to ask before signing a Sunrun proposal
- What is the year-one rate or payment, the annual escalator, and the year-25 payment? Ask for a year-by-year table.
- What production is guaranteed, and how is a shortfall paid?
- Who pays to detach and reinstall panels if the roof needs work?
- What are the transfer and buyout terms if you sell? See our guide to solar loan vs lease vs PPA.
- Is the salesperson a Sunrun employee or a contractor, and is every promise in the signed contract?

Frequently asked questions
Is Sunrun a good solar company?
Sunrun is the largest U.S. residential provider and many owners are satisfied, but its reviews are mixed. SolarReviews averages 2.88 stars while BBB shows an A+ with thousands of filed complaints. Judge the specific contract: escalator, production guarantee, buyout terms and who handles service in your area.
Does Sunrun sell panels or only leases?
Sunrun's annual report names leases and power purchase agreements as its core offerings, with initial terms typically 20 or 25 years. Ask your salesperson which options are available in your state and compare any purchase option to local installer quotes.
What are the most common Sunrun complaints?
Reviewers report slow repairs, hard-to-reach support, billing errors, disputes over roof work and savings that fell short of what was described. These are customer-reported experiences, not findings of fact, and Sunrun replies to many reviews. Read your contract's service and guarantee language closely.
Did Sunrun settle with a state attorney general?
Yes. In October 2026 Connecticut's Attorney General announced a settlement of a 2024 suit over sales practices. Sunrun agreed to pay $300,000 and offer remedies to affected customers. The defendants did not admit liability, and the settlement addressed conduct tied to a sales contractor.
Can I cancel a Sunrun contract?
Door-to-door sales usually carry a federal three-business-day right to cancel, and some states give more time. After that, cancellation depends on your contract and project stage. Put any cancellation in writing and keep proof of delivery.
