Solar power system warranty period

Solar power system warranty periods are often divided into two main types:

  • Standard warranty period
  • Extended warranty period

Let’s start with a detailed analysis of each warranty period.

Standard warranty period

The standard warranty period for solar power systems is usually specified as follows:

  • Product warranty: Typically, solar panels have a 25-year performance warranty, ensuring the panels maintain a minimum of 80% output compared to their original design capacity after 25 years. Solar grid-connected inverters are usually warranted for 5 years.
  • Installation warranty: Normally, the solar power system installation warranty is 1 year.

Extended warranty period

In addition to the standard warranty period, some solar power system suppliers and installers also offer extended warranty periods. Extended warranties may apply to both the product and installation.

Extended warranty periods are often added to the standard warranty period. For example, a solar power system has a standard product warranty of 25 years. If the customer purchases an extended warranty period of 10 years, the product warranty period will be 35 years.
