MasterResource has chronicled the rise and fall of Enron-ex John Berger’s rooftop solar company, Sunnova Energy International Inc.[1] [some emphasis, links added]
The whole rooftop solar proposition was dicey, even with taxpayer and ratepayer subsidies.
“Subsidies like the DOE’s guarantees can incentivize firms to prioritize short-term gains over long-term compliance,” observed Issac Lane.
“Sunnova’s aggressive sales tactics, which targeted vulnerable consumers, were enabled by its belief that federal backing insulated it from accountability.”
What is the latest, where Berger exited with millions of dollars and almost everyone else footed his bill (including taxpayers)? An AI search for “Criticism of Sunnova Energy” revealed:
Sunnova Energy, once one of the largest U.S. residential solar providers, has faced widespread criticism from customers, watchdogs, and industry observers following its 2025 bankruptcy filing.
Customer complaints and service issues
Homeowners have reported problems such as unfinished or delayed installations, canceled service and maintenance agreements, and ongoing loan obligations for systems that never worked. (orphananniesolar.com). Some customers say they were left paying for solar systems that were never completed, while others faced long delays in repairs or replacements. A Reddit homeowner even warned others to “stay away” after being left with a defunct system for months. (The Cool Down).
Reputation damage from sales practices
Critics have pointed to allegations of misleading sales tactics and poor-quality installations by Sunnova’s third-party dealer network. (blog.prevostlawfirm.com). The company’s reliance on external sales teams, while helping it scale quickly, also made it vulnerable to unethical practices and inconsistent service quality. These issues have eroded consumer trust and contributed to reputational harm.
Financial and operational failures
Sunnova’s collapse was driven by massive debt (around $8.9–10.67 billion), high interest rates, regulatory uncertainty, and declining residential solar demand. (EnergySage+1).
The bankruptcy came after a $3 billion Department of Energy loan guarantee was terminated, and the company had already laid off over half its workforce. (EnergySage). Critics argue that aggressive growth and heavy debt loads without sufficient safeguards left the company exposed to market shocks.
Industry and legal scrutiny
Legal experts and consumer protection advocates have highlighted that Sunnova’s bankruptcy raises questions about contract enforcement, warranty rights, and consumer protection in the solar sector (orphananniesolar.com+1).
Some warn that customers may face long delays in resolving disputes or receiving service, and that future claims could be complicated by the bankruptcy process.
Key takeaways for consumers
The Sunnova case has become a cautionary tale in the solar industry, underscoring the importance of:
- Researching a company’s financial health before signing contracts.
- Understanding all terms, especially service and maintenance obligations.
- Avoiding tying financing solely to the installer.
- Keeping all documentation in case legal action is needed (orphananniesolar.com).
In short, Sunnova’s criticism centers on poor customer service, questionable sales practices, and financial mismanagement, which together contributed to its downfall and left many homeowners in a difficult position.
It is very peculiar for rooftop solar advocates to raise their heads today. But so-called distributed generation is still in the planners’ plans. Elisa Wood, energy writer and editor, wrote:
“A 75-year-old science group offers a new direction following the Trump administration’s climate rollback. Here’s why the plan features rooftop solar, batteries, microgrids and other forms of distributed energy.”
I challenged her with the Sunnova example, and she responded:
“Logical fallacy here. One company’s bankruptcy doesn’t damn a whole technology.”
And I answered with a long, long list of U.S. solar bankruptcies that exceeded the word limit, so it is in two parts (here and here).
Final Comment
Journalists stuck in the climate alarmist, forced energy transformation mode are in a pickle. One hopes they can find another employment short of changing their views internally, a very difficult process.
But Ms. Wood is at the beginning of her career. Maybe watching this video of Richard Feynman, “The Easiest Person to Fool Is Yourself“, will help the process. And as Milton and Rose Friedman noted (Free to Choose, 1979, p. xii):
“The only person who can truly persuade you is yourself. You must turn the issues over in your mind at leisure, consider the many arguments, let them simmer, and after a long time turn your preferences into convictions.”
