- SunPower Corporation stands as a prominent provider of residential solar and advanced energy solutions across the United States and Canada. The company, which rebranded from Complete Solaria, Inc. in October 2025, centers its operations on delivering comprehensive home energy ecosystems. Its product portfolio encompasses high-efficiency solar panels, integrated battery storage solutions such as the SunVault, and intelligent monitoring software accessible via the mySunPower app. These offerings combine to create a seamless energy system, allowing homeowners to generate, store, and manage their clean energy consumption effectively. While the company no longer manufactures its own panels, it collaborates with leading suppliers and partners for advanced components, like Enphase microinverters for energy storage, maintaining a focus on high-performance technology. SunPower's revenue generation stems from a multifaceted approach, including direct sales, long-term leasing options for residential customers, and sales conducted through an extensive network of third-party dealers. This is complemented by robust installation services, comprehensive system warranties, and ongoing maintenance support. The company's strategic emphasis is squarely on the residential sector, serving individual homeowners and partnering with new home builders to integrate solar technology into new constructions. In a period of significant strategic realignment, SunPower has actively expanded its market presence. Key recent developments include the acquisition of Sunder Energy in September 2025, which substantially widened its state coverage and sales capabilities, and a letter of intent to acquire Ambia Solar in November 2025. These moves underscore the company's commitment to growth and strengthening its position in the residential solar market, supported by strong shareholder backing, including a term loan from Sol Holding, LLC, a joint venture involving TotalEnergies SE. SunPower Corporation, initially founded in 1985, is now headquartered in Fremont, California.
