A better warranty starts with a better product

Every part of your SunPower EquinoxTM system is meticulously designed to work perfectly together, and all the components are rigorously tested for long-term reliability. That's why the SunPower® Complete Confidence Warranty is the only solar warranty to cover your whole system (not just the panels).


Pitfalls of typical conventional solar warranties

Each manufacturer’s warranty covers one component of the entire system, leaving you with at least 4 separate warranties (panel, inverter, racking, monitoring). With a conventional solar warranty:

  • You must pay to package and ship defective panels
  • You must present the original physical proof of purchase
  • You must pay to replace panels damaged from rust
  • Hardware functionality is treated as binary (either it's on or off)

Benefits of our Complete Confidence warranty

SunPower is the only company that stands behind your entire system, not just the panels. We also:

  • Provide repair or replacement at no additional cost; includes labor and shipping
  • Don’t require receipts, proof of purchase or written claims
  • Cover rust damage, such as in seaside installations
  • Treat the system as a whole
