25-Year Industry-Leading Warranty

The SunPower® Complete Confidence Warranty is the only home solar warranty to cover your whole system (not just the panels), so you never have to wonder which company you can depend on.


A better warranty starts with a better product

Every part of your SunPower Equinox™ system is meticulously designed and built by SunPower to work perfectly together, and rigorously tested for long-term reliability.


Pitfalls of conventional solar warranties

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

  • Pay to package and ship defective panels
  • Present original physical proof of purchase
  • Pay to replace panels damaged from rust

  • 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
