SunPower

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.

SunPower publishes 3 APIs on the APIs.io network. Tagged areas include Solar Energy, Renewable Energy, Photovoltaics, Open Source, and Python.

SunPower’s developer surface includes engineering blog and 4 more developer resources.

  name: pvfactors
  description: pvfactors is an open-source Python library for modeling diffuse shading and bifacial photovoltaic (PV) irradiance.
    It implements 2D geometry and view-factor mathematics to account for reflections between array surfaces including front
    and back sides of bifacial modules, ground, and sky. Used by PV professionals for simulation of complex shading scenarios,
    time-series irradiance calculations, and energy yield assessment. Maintained under the SunPower GitHub organization.
