What warranties come with my system?

There are three main warranty categories:

• Product warranties:
  • Cover potential defects with your solar modules and inverter.
  • Offered by the manufacturer, not your installer.
  •  Modules typically carry a 10-year workmanship warranty but can range up to 25+ years.
  • Inverter warranties may range from 10 to 25 years. They can often be extended for an additional fee. Check with your installer on availability and pricing.
• Power production warranties:
  • Guarantee the output of solar modules won’t decrease by more than a certain percentage per year.
  • Guarantee your panels still produce some percentage (usually 80% or more) of their initial rated capacity for a minimum number of years.
  • Offered by the equipment manufacturer (not your installer).
• Labor/installation warranties:
  • Cover the craftsmanship of work done by installer to assemble equipment into a working system on your property.
  • Typically includes warranty on all roof penetration points as well.
  • Installer workmanship warranties cover issues related to their installation work such as wiring and conduit, racking assembly, and roof penetrations. Typical timespan is 3 to 10 years, though some can be as long as 20 years or more.
