There are generally two main types of warranties associated with solar panels:

  • Manufacturer’s Warranty (Materials or Workmanship Warranty)
  • Performance Warranty

1. Manufacturer’s Warranty (Materials or Workmanship Warranty)

This type of warranty covers any defects in the materials or workmanship of the solar panel. If a panel fails due to a manufacturing defect or poor quality of workmanship, the manufacturer is obligated to repair, replace, or refund the faulty panel. Manufacturer’s warranties typically last between 10 to 12 years, although some premium brands offer longer periods.

2. Performance Warranty

Performance warranties guarantee that the solar panels will produce electricity at a certain efficiency level for a specified period, usually 25 years. These warranties assure that the panels will not degrade faster than a certain rate, ensuring that they will still be producing a minimum percentage of their original output by the end of the warranty period. For example, a performance warranty might guarantee that after 25 years, the panels will still produce at least 80% of their initial output.

What is an inverter warranty?

An inverter warranty is a formal assurance provided by the manufacturer that guarantees the quality and performance of the solar inverter for a specified period. Solar inverters are critical components of a solar energy system; they convert the direct current (DC) generated by solar panels into alternating current (AC) that can be used in your home or fed back into the grid.

Types of Inverter Warranties:

  • Standard Manufacturer’s Warranty
  • Extended Warranty

1. Standard Manufacturer’s Warranty

This is the basic warranty that covers defects in materials and workmanship. If the inverter fails due to a manufacturing defect within the warranty period, the manufacturer is obligated to repair or replace the unit. Standard warranties for inverters usually range from 5 to 12 years.

2. Extended Warranty

Some manufacturers offer the option to purchase an extended warranty, which can prolong the standard warranty period. This can be particularly useful for high-quality inverters that are expected to have a long operational life.

  • Material Defects: Any defects in the materials used in the inverter.
  • Workmanship: Any defects arising from the manufacturing process.
