We analyzed BBB complaints, CFPB filings, and state AG actions to rank the solar companies generating the most consumer complaints in 2026.
## Which Solar Companies Have the Most Complaints?
If you're researching a solar company — or already dealing with one that isn't living up to its promises — you're not alone. Thousands of American homeowners file complaints against solar companies every year through the Better Business Bureau, the Consumer Financial Protection Bureau, and state attorneys general offices.
We compiled complaint data from public sources to identify the solar companies generating the most consumer frustration in 2026. This isn't about which company is "worst" in some abstract sense — it's about giving you the data so you can make informed decisions.
## The Top 10 Most Complained-About Solar Companies
### 1. Sunrun — ~2,800 BBB Complaints
Sunrun is the largest residential solar company in America, so some volume of complaints is expected. However, the patterns are concerning: customers consistently report that their systems produce less energy than sales representatives promised, that lease escalator clauses were not clearly explained, and that reaching customer service for warranty claims requires extraordinary patience.
### 2. Pink Energy (Formerly Power Home Solar) — ~2,100 BBB Complaints
Pink Energy collapsed in late 2022, leaving thousands of customers with non-functional systems, voided warranties, and ongoing loan payments. This is the cautionary tale of the solar industry. If you have a Pink Energy system, your options are limited but not zero.
### 3. Vivint Solar / NRG Energy — ~1,900 BBB Complaints
Acquired by Sunrun in 2020, former Vivint Solar customers have experienced significant service disruptions. Warranty claims that predated the acquisition remain unresolved in many cases, with customers caught between two corporate entities.
### 4. SunPower — ~1,875 BBB Complaints
Once the premium brand in residential solar, SunPower filed for Chapter 11 bankruptcy in 2024. Thousands of customers are now uncertain about warranty coverage and ongoing service commitments. The bankruptcy has left a trail of unanswered service requests.
### 5. Momentum Solar — ~1,675 BBB Complaints
Operating primarily in the Northeast, Momentum Solar has been the subject of a New Jersey AG lawsuit for deceptive sales practices. Complaints center on high-pressure door-to-door sales tactics and significant gaps between promised and actual energy savings.
### 6. Tesla Solar — ~1,567 BBB Complaints
The Tesla brand carries enormous consumer trust, but the solar division has struggled with operational execution. Installation timelines of 6-12 months, unilateral price changes after contract signing, and a customer service model limited to app-based communication are recurring themes.
### 7. GoodLeap (Solar Financing) — ~1,456 BBB Complaints, ~892 CFPB Complaints
As the largest solar loan provider, GoodLeap deserves special attention. The CFPB has received hundreds of complaints about hidden dealer fees that inflate loan balances 25-40% above actual system costs. Many borrowers report not understanding they signed a loan versus a lease.
### 8. Freedom Forever — ~1,534 BBB Complaints
Freedom Forever's 25-year production guarantee sounds compelling, but consumers report disputes over how production shortfalls are measured and compensated. The company's heavy reliance on subcontractors creates inconsistent installation quality.
### 9. Sunnova Energy — ~1,345 BBB Complaints
Sunnova's dealer model means your installer and your financing company are separate entities. When something goes wrong, customers often find themselves caught in a blame game between the two, with neither accepting responsibility.
### 10. ADT Solar — ~1,245 BBB Complaints
Formerly Sunpro Solar, ADT Solar leverages the trusted ADT brand name in door-to-door sales. Consumer advocates have criticized this as misleading, since the solar division operates largely independently from ADT's security business.
## What These Numbers Mean for You
High complaint counts don't automatically mean a company is terrible — larger companies naturally generate more complaints. But the patterns matter. When thousands of customers report the same issues — misleading sales promises, installation delays, unresponsive service — that's a systemic problem, not isolated incidents.
## What to Do Before Signing a Solar Contract
1. **Search the BBB** for your specific company and read recent complaints
2. **Check the CFPB database** if you're financing through a solar loan
3. **Search your state attorney general's website** for any enforcement actions
4. **Get multiple quotes** from at least three different installers
5. **Read every word** of your contract before signing — especially the escalator clause
