SunPower is a residential solar energy company (Nasdaq: SPWR) that designs, installs, and finances solar systems and battery storage for homeowners. The original SunPower Corporation filed for Chapter 11 bankruptcy in August 2024; its assets were acquired by Complete Solaria in September 2024, which rebranded as SunPower Inc. in April 2025. SunPower maintains the GitHub org github.com/SunPower, hosting open-source solar modeling tools including pvfactors (view-factor model for bifacial PV modeling), PVMismatch (mismatch loss calculations), and SolarUtils. These Python libraries are used by solar energy professionals and researchers for photovoltaic system modeling and simulation.
