Sunnova Energy International Inc.

Sunnova Energy International Inc., founded in 2012 and headquartered in Houston, Texas, is a leading U.S. provider of residential solar energy and battery storage services. Operating primarily across the United States—including territories such as Puerto Rico—Sunnova partners with local contractors to deliver rooftop solar installations, advanced battery storage solutions, system maintenance, and repair services to homeowners seeking reliable clean energy alternatives. The company offers flexible financing options including $0 down payment plans and backs its systems with a 25-year service commitment.
Notably recognized for innovation within the renewable sector, Sunnova has received industry accolades for expanding access to distributed solar power and pioneering virtual power plant-ready software that empowers customers to monitor usage patterns and reduce carbon emissions. In September 2023, Sunnova secured a $3 billion partial loan guarantee from the U.S. Department of Energy for Project Hestia—a large-scale initiative aimed at deploying distributed rooftop solar plus batteries nationwide while supporting over 3,400 jobs. As of 2023 financials: revenue reached $1.4 billion with approximately 1,200 employees. Despite rapid growth and recognition for climate impact efforts—such as an estimated avoidance of over seven million tonnes of CO₂ emissions through Project Hestia—the company has also faced scrutiny regarding customer service practices but continues to invest in improving support systems.
