Sunnova Energy Corp., among the largest U.S. residential solar third-party ownership providers, is planning an initial public offering that could value the Houston-based company at more than $1 billion including debt, according to a Tuesday report from Reuters citing anonymous sources.
Sunnova declined to comment on Reuters’ report that it has filed confidential documents to hold an IPO later this year. The company, founded in 2012, has seen more than $2.5 billion in investment from backers including Energy Capital Partners, Triangle Peak Partners, and Quantum Strategic Partners.
Sunnova has built up a significant market share in the residential solar financing market, providing leases and loans for systems installed via a nationwide network of contractors. At the end of 2018, Sunnova was the fourth largest residential solar third-party ownership (TPO) provider in the United States, behind Sunrun, Vivint Solar, and SunPower, according to Wood Mackenzie Power & Renewables’s U.S. Residential Solar Finance Update.
What differentiates Sunnova from these competitors, however, is that Sunnova also provides residential solar loans, allowing the company to take advantage of that growing market as well, Alison Mond, WoodMac solar analyst, noted Tuesday.
At the end of 2018, Sunnova was the seventh largest residential solar financier overall, including both TPO players and loan providers, behind Sunrun, Mosaic, Loanpal, Sunlight Financial, Vivint Solar, and Dividend Finance.
Sunnova has raised more financing than some of its biggest competitors that have also taken the IPO route. For example, Sunrun had raised $681 million in venture financing when it went public in 2015, raising another $251 million to achieve an initial market capitalization of $1.36 billion. SolarCity (now Tesla) raised roughly $90 million in its 2012 IPO to achieve an initial market capitalization of about $600 million.
But then, of course, the U.S. residential solar market is much larger, and the products being sold and financed much cheaper, than they were even a few years ago. Sunnova’s most recent raise of $775 million in April 2017 included the company’s first asset-backed securitization, and one of the largest in the industry’s history.
Sunnova’s reported IPO may give the market a measure of investors’ appetite for a residential solar provider that relies solely on its network of regional dealers and contracts to install the solar and storage systems it sells, WoodMac solar analyst Austin Perea noted.
By contrast, Sunrun, Tesla/SolarCity, Vivint, and SunPower all do a combination of direct and channel partner installations. “The question to ask here would be whether Sunnova’s IPO says anything about the long-term viability of the national installer model,” Perea said.
Sunnova has also followed its competitors into the business of providing behind-the-meter batteries alongside solar systems, launching its SunSafe product in March 2018 and now selling in California, Arizona, Hawaii, Puerto Rico and Texas. That’s compared to market leader SunRun, which sells its BrightBox package to Hawaii, Arizona, Nevada, New York and Massachusetts.
