SunPower
Mixed (C) — Insolar Honesty Grade
SunPower filed Chapter 11 bankruptcy in August 2024 after decades as a premium solar brand. Customer service and warranty support disrupted; existing customer base has been split across successor entities. New SunPower under Complete Solaria branding is rebuilding service standards. Historical product quality (Maxeon panels) remains industry-leading.
